Animals are our friends． Sometimes they make trouble， but sometimes they can help us．And they hope to live a happy life， too． Here are two real stories from our readers．
The first story is from Ray．"My cat， Tiger， hates it when I use my iPad because it takes my attention away from him． One year， I had a fall at home and was on the floor for 16 hours， During this time， I was unable to move and couldn't get to the phone to call for help． Tiger stayed by my side until he disappeared under my bed． 'What's he up to？' I wondered． To my surprise， he started to push something towards me． It was my iPad，which I didn't realize had fallen off the bed and onto the floor．He probably didn't know what it was， but he knew that it made me happy． Thanks to Tiger， I was able to communicate with my friend， Becky， who then told my doctor．"
The second story is from Colin． "Years ago， my friend Julius saved a bird﹣a wild 'Mom' cockatoo（鹦鹉） from the side of the road and kept it as a pet in a big cage（笼子）．It lost one of her wings， so she was unable to return to the wild． Soon， two wild cockatoos came visiting and one 'Dad' bird wanted to find his way into the cage． The 'Mom' cockatoo in the cage was soon expecting． But as she couldn't fly，'Dad' cockatoo built a home in the tree， keeping off everyone who got close to 'Mom' cockatoo． 'Baby' cockatoo would spend his days flying off with his dad， leaving his mom behind．She would sit and wait until they returned home each afternoon．The family stayed together happily．"
After reading the stories， don't you think we should get along well with animals？ No matter they are our pets or live in the wild， they have their feelings． We should respect every life in the world．

Have you ever paid for educational podcasts （播客） or live videos？ Ask some people and most of them will say yes． "Pay﹣for﹣knowledge" has been more and more fashionable these years． The contents of these "pay﹣for﹣ knowledge" products are from language learning to gardening or baby﹣caring． Everything you think of can be found online at this moment． "Pay﹣for﹣knowledge" is on the rise （兴起）．
Why is "pay﹣for﹣knowledge" industry developing so rapidly？ First， its development is based on the Internet． With a fast network and a smartphone， anyone who has passed the identity （身份）check can be an online teacher， and anyone with an online account can buy "pay﹣for knowledge" products that he or she wants at an affordable price． Second， people are afraid to miss any information． On one hand， people hope for more useful information． On the other hand，such information is usually at the hands of experts （专家） who serve well﹣known companies and universities．Moreover，the need to learn new skills in today's job market also pushes people to learn on such educational podcasts．
The industry of "pay﹣for﹣knowledge" has proved to be lucrative． It promises possibilities of turning information into money． It is good for the development of our country and it can help sellers make lots of money． Besides， buyers can enjoy self﹣growth from it．What's more， this is a reflection （反映） of respect for knowledge and talents．
However，the rapid development of "pay﹣for knowledge" has a few problems．For one thing，the market is full of eye﹣ catching words such as "How to be an Industry's Expert in 5 Hours" and "15 Classes to Be a Master of Appreciating （欣赏） Classical Music"， which sound like if you pay for it， you are sure to succeed． For another， a large number of customers buy them just for showing off． In fact， those who have really had self﹣growth after buying online courses may be the kind of people who need them least． In other words， with or without these courses， they can make it anyway，because they are those who have the ability to learn by themselves．
In general， the best is the one that suits you most．"Pay﹣ for﹣knowledge" may be used as a good start for self﹣ growth． Be careful! Otherwise， your dream of success may not come true．

（2）What can we learn about "pay﹣for﹣knowledge" industry from Paragraph 2？
A． The history of its development．
B． The problems of its products．
C． The advantages of its products．
D． The causes of its rise．
（3）The underlined phrase "be lucrative" in Paragraph 3 means" "．
A． produce lots of money
B． get much information
C． win great respect
D． enjoy self﹣growth
（4）The main purpose of this passage is to ．

Since May 8， Boston Dynamics， doglike robot， Spot， has been in use at BishanAng Mo Kio Park in Singapore to help encourage social distancing during the COVID19 pandemic （新冠肺炎疫情） according to a report in the South China Morning Post．
Singpore’s government is funding the experiment of the robotic dog， which will last for two weeks at the park during offpeak（非高峰的） hours．
"The robot isn’t enforcing （强制 ）． It’s just giving people information and encouraging them， "Boston Dynamics founder Marc Raibert told CNBC． "When Spot is patrolling（巡逻）the area， there’s a parks officer nearby who can do whatever enforcement he decides is suitable． "
Cameras fixed on Spot will scan the surroundings and help officers work out the number of visitors in the park， but they cannot read faces and won’t collect any personal information． It also carries a loudspeaker to broadcast a prerecorded message to remind visitors of the importance of social distancing．
Without enough manpower， Singapore is turning to robotics to reduce the manpower required for park patrols and remind people about the risks they may be putting themselves and others in．
The question， however， is whether their use of Spot will be a good tool or will or only attract more people to it instead．
If the twoweek experiment proves successful， the government will consider using Spot at the park during peak hours． Singapore will also do studies to see if it’s worth using other Spots in other parks． Already， Singapore engineers are trying to improve Spot， making it tell if people are together in a group or strangers passing on the grass．
No one knows if Spot will stay after the pandemic is gone， but one thing is for sure： the robot is the hardest working dog in the world．
（1）Why is Spot used at BishanAng Mo Kio Park？
A． To draw visitors， attention to it．
B． To help encourage social distancing．
C． To read and record visitors， faces．
D． To help collect private information．
（2）The underlined word "they" in Paragraph 4 refers to（指的是） ．
A． visitors
B． strangers
C． cameras
D． officers
（3）What can we learn from the last 3 paragraphs？
A． The experiment is still in progress．
B． The use of Spot proves to be a good tool．
C． Spot will stay after the pandemic is over．
D． Singapore will no longer need other Spot robots．
（4）According to the passage， which of the following is TRUE？
A． Spot scares people into keeping a distance in public．
B． Spot patrols the park for two weeks during peak hours．
C． Spot can tell people together in a group from strangers passing by．
D． The parks officer nearby decides on the enforcement instead of Spot．
At the doctor's office
Wilson is a foreign student in Britain．He is learning English there．He still has some trouble using the language．
Doctor： Good morning． You're a new patient， I think． What's the trouble？
Wilson： Sometimes I feel cold and sometimes hot． I have a headache and a stomachache． Doctor：Yes， you look a bit off﹣colour．
Wilson： What colour， please？
Doctor： Sorry， what I said was "off﹣colour"．We use it to describe how people look or feel when they are unwell． Let me take your temperature． When did this start？
Wilson： I felt very tired last night when I went to bed． Then I felt really bad this morning when I woke up．
Doctor： I see． Now， let's look at your temperature． Ah， just as I thought， a hundred and one．Wilson： Oh， a hundred and one？ So high？
Doctor： Ah， yes， that must sound strange to you． We measure people's temperature on the Fahrenheit scale（华氏）． In centigrade， your temperature is 39℃， which is a bit high， but not exactly boiling point（沸点）．
Wilson： Oh， it isn't very bad， then．
Doctor： No， it isn't serious． You've got a cold． I'll give you some medicine． You'd better stay at home in the warm for a day or two and drink plenty of water．
Wilson： Thank you very much， doctor． I'm feeling better already． It wasn't so difficult telling you about my illness．
Doctor： No， language doesn't matter too much to a doctor． After all， vets manage without language at all．
Wilson： Please， what's a "vets"？
Doctor： Animal doctors． Now I must end this English lesson and see my next patient．
（1）Which word has the same meaning as the underlined word "off﹣colour"？

I think there are several reasons that suggest developing robots is a waste of money．
In San Diego recently ＄ 325，000 was spent on inventing a robotic squirrel to do some scientific experiments． The research proved that squirrels are able to scare away snakes by wagging （摇动） their tails． Do you need a robotic squirrel to work this out？
What about AIBO，a robotic pet，developed in Japan？ In Japanese aibou means "buddy"． These pets have been developed at huge cost mainly to provide entertainment．They've been used in movies and music videos． Universities have used them for educational purposes．However， in 2006 the company stopped producing these robotic pets in order to save money． Was it worth a lot of money？
Then there's NAO， a robot which has been developed by a French company．Its main purpose is to make life easier for humans． It speaks 19 languages and has its own personality．It can tell children a story， help in the classroom or the home， or act as a companion to those people who need someone to be with．A fully developed one costs ﹩16，000． Is that value for money？ Who can afford it anyway？
There may be good reasons why it is worth developing robots， but so far I haven't thought of any．
（1）What does the underlined word "companion" in Paragraph 4 mean in Chinese？
A．公司
B．机构
C．对手
D．伙伴
（2）What is the true fact about the robots mentioned？
A． The robotic squirrel is needed by every scientist to do some research．
B． AIBO wasn't made any more because it only provided entertainment．
C． A fully developed NAO may tell kids stories in different languages．
D． All the three types of robots used to be produced at a very low cost．
（3）What does the writer think of developing robots？
A． It can help bring people a lot of fun．
B． It has advantages in many ways．
C． It may be useful but costs too much．
D．It is worth a great deal of money．
Do you like Physics or Chemistry？ Matter （物质） is always changing， either physically or chemically． If a material goes through a physical change， it is still the same material． During a chemical change， one kind of matter changes into another completely different kind of matter． For example， when we burn wood or cook fish， materials change． People use chemistry every day in the kitchen． The food we eat has many different natural chemicals． Many of the chemicals in food are necessary parts of a healthy diet．
Much of the food we eat has been changed in some way from its original form． The changes that food undergoes may be chemical or physical． If a change does not affect the food's chemical composition， we call it a physical change． For example， melted （溶解的） cheese has gone through a physical change． It gets softer when it is heated but it is still the same type of material． Any change that changes the chemicals in the food is a chemical change． Bread contains carbohydrates， which are chemicals made up of carbon， hydrogen， and oxygen． When bread is baked （烘焙）， the carbohydrates break down into black carbon and water． The carbon gives the bread a dark color and a crunchy texture （质地）． The water goes into the air．
To get a closer look at the chemistry of baking， let's watch how a carrot cake is made． The main steps of baking any cake are mixing the ingredients （材料） and baking them together． In the course of making cakes， the dry ingredients are mixed first． They are flour， sugar， salt， baking soda， baking powder and spices． Flour gives the cake structure． Sugar helps to make it sweet． Salt strengthens the cake batter． Baking powder and baking soda make the cake rise．
Next， the carrots may be added to the cake． These help give the carrot cake its flavor， texture， and color． The other ingredients in the carrot cake are oil and eggs． The oil makes the cake tender and moist． Eggs serve two purposes﹣the whites help the cake to rise， while the yolks （蛋黄） give it a creamy texture． All of these ingredients form a mixture． This mixture can be separated into its different components （成分） although it is very difficult． Once the cake mixture is formed， it's poured into a cake pan and baked in an oven． The heat from the oven has caused chemical changes to take place． The cake is finished and the ingredients cannot be separated．
（1）The material doesn't change when we ．
A． melt ice cream
B． burn paper
C． bake apple pies
D． cook beef
（2）What's the correct order of baking a carrot cake in the passage？
a． Carrots， oil and eggs are added．
b． The dry ingredients are mixed．
c． The mixture is baked in an oven．
d． Baking powder and soda make the cake rise．
e． Preparing some dry ingredients．
f． The heat from the oven causes chemical changes．
g． The ingredients cannot be separated．
h． The mixture is poured into a pan
A． b﹣a﹣h﹣f﹣g
B． b﹣h﹣c﹣d﹣f
C． e﹣d﹣c﹣a﹣g
D． e﹣c﹣a﹣g﹣d
（3）After reading the passage， we know that ．
A． water and carbon can give the cake a dark color and a crunchy texture
B． people can separate the mixture of eggs and oil into different components
C． chemicals in different kinds of food that people eat are bad for their health
D． sugar and salt can't be put into the mixture to make a cake at the same time
（4）The passage mainly helps us to ．
A． look at the steps of baking cakes closely
B． learn how to make carrot cakes at home
C． have a healthy diet with natural chemicals
D． understand physical and chemical changes
Recently children have been told to buy traditional alarm clocks instead of mobile phones to wake them up in the morning． Schools will advise pupils to turn off mobile phones or iPads in the evening to have enough sleep．
Researchers from a charity say that using internet﹣connected devices（装置）in the evening can prevent children getting more rest． Moreover， they suggest that school children should invest in a real alarm clock to make sure that they get a good night's sleep and arrive at school on time．
①_____． The result is that 40% pupils in secondary schools can now hardly get on well without these devices． About two﹣thirds of pupils have a habit of taking mobile phones to bed at night．
②______．The study also shows that girls are more likely to be attracted by mobile phones than boys， and often use the Internet to talk to friends by social networking websites， such as Facebook and Twitter． One girl aged 12 said， "I have been told that I am addicted（上瘾的）to the Internet， and prefer being online to being with other people．"
③_______．A girl of 13 told researchers， "I can't imagine if someone takes my iPad away． I walk around the house with it even though it's not turned on． I just like being with it．" Another girl added， "Sometimes I can't sleep without using the mobile phone at night．"
④______．The charity， which was set up to promote（推动）iPads in the classroom， has now given five suggestions to protect children from being affected by electronic（电子的）devices．

Around the world， people live in homes of many shapes and sizes． In some countryside， people live together with their family in a huge house with gardens or backyards． On the other hand， the buildings in cities are usually very close together．
A home can be any kind of building﹣ large or small． Some people even have homes on boats， in tents or in caravans that can be moved around． Caravans are mobile homes． They are towed（拖，拉） by either a car or a huge truck． Some of them are holiday homes． We can see many families staying together in these caravans．
In the past， rich and important people built strong castles to keep their families safe． The castles（城堡） were built on hill tops with high walls and some even had moats． Moats were deep and wide ditches（壕沟） filled with water． They made it difficult for enemies to attack．
Today， we have different ways of protecting our homes． Some homes are installed（安装） with video cameras and an alarm system． These will help to alert（向……报警） home owners if someone tries to break in．
Homes are important to all the people． Everyone needs a home where they feel sheltered and safe．
（1）How are the buildings in cities？
（2）What is used to tow the caravans？
（3）Who built castles to keep their families safe in the past？
（4）Why were moats built？
（5）What do people use to protect their homes today？
（1）One of my friends sometimes takes aside another friend to talk to her about something she doesn't want me to hear． It makes me feel sad． What should I do？
（2）Some of my friends are in a fight． like them all equally（同样地）， but they say I have to choose sides． Help!
（3）I look up to my sisters． They're both intelligent（聪明的） feel that I'll never be as good as them．
（4）I am the shortest person in my class， and my classmates call me "Tiny Mouse． " How can I make them stop？
（5）I always use the computer and can't stop I feel that I'm not getting any smarter and the computer is warping（扭曲） my brain．
A． It's wonderful that you admire them． but try not to compare yourself to them． Instead of trying to be like them， just try to be the best you possible． You will find that you will be much happier when you try to be true to yourself， rather than when you try to be like someone else．
B． The only way to break a habit is to force yourself to do something different． A world of exciting and interesting activities is just waiting for you． Write a list of things you've always wanted to do， learn， make， or try． When you feel like playing it， do something else．
C． Discuss this with her． Try not to suppose that she talks about you unless you actually hear what she says． But let her know that you are unhappy when she tells secrets around you． If you feel uncomfortable talking to her in person， you could write her a note instead．
D． We often hear from kids who are laughed at about their height． They probably don't mean to hurt your feelings． There are advantages and disadvantages to being any size． You might play along and come up with a funny reply． However， if you feel hurt， try talking to a parent or teacher．
E． Explain to your friends that you like all of them． You can play with each person or group separately． If they don't like this， then you may want to focus on other friendships until these friends work things out． Another idea is to offer to help your friends solve their problems．
Do you often listen to music at loud volumes？ You should know that this habit is bad for your hearing． Over 1 billion young people are at risk of hearing loss（听力丧失）， because of listening to loud noise for long periods of time． Listening to music or watching a TV show at loud volumes can harm your hearing．
The United Nations has standards for safe listening． It is not safe to listen to sounds that are louder than 85 dB （分贝） for eight hours or 100 dB for 15 minutes．The sound of a busy road is about 85 dB and the sound of a rock concert can be about 100 dB．
Loud noise is harmful to the inner ear． Most of us are born with about 16，000 hair cells（听毛细胞） in our inner ears． These cells notice sounds． However， listening to loud noise for a long time can make these cells work too hard and cause some of them to die． This is what causes hearing loss Once this happens， it's hard to get your hearing back．
Some people might think that their music isn't all that loud． But this can depend on where you are． For example， if you are in a noisy place like the subway， you might turn up your music too loud without realizing it． Later， when you listen to it at the same volume in a quiet place， you might feel uncomfortable．
The "safe level" for most sound is below 80 dB for up to 40 hours a week． a level of 80 dB is about equal to（相当于） the noise of a subway．
Here is some advice on safe listening． Over﹣the﹣ ear headphones（头戴式耳机） are better than in﹣ear ones． They do a better job of stopping outside noise， so you can listen at a lower volume．Don't listen to loud music on your headphones for a long time． Follow the 60： 60 rule： listen to music at 60 percent of your headphones' maximum volume for no more than 60 minutes a day．
根据短文内容，判断下列句子正误．正确的用"A表示，不正确的用"B"表示．
（1）It is safe to listen to sounds that are louder than 100 dB for 15 minutes．
（2）Listening to loud noise for a long time can cause some hair cells in the inner ear to die．
（3）From the fourth paragraph， we know people don't always realize how loud their music is．
（4）In﹣ear headphones are better than over﹣the﹣ear ones because they can stop more outside noise．
（5）This article mainly tells us why ears are an important part of our bodies．
Obey the rules of British roads
British roads， some of the safest in the world． A study in 2018 compared more than 30 countries and found that 3.8 people per 100，000 died in traffic accidents in the UK． This number was lower than any other country． So， what did British drivers do to achieve this？ What are they doing differently？ Here are five top tips for drivers who are planning a trip to the UK．
People in Britain drive on the left side of the road． In fact， a long time ago people drove on the left in most countries， but now only a few countries have this． Don't forget that this also means you must drive the other way around roundabouts （ 环岛）．
British people feel that waiting should be fair for everybody． If you are in a queue of traffic，then don't try to push past the cars in front of yours． This is called "jumping the queue"． You must wait for your turn； otherwise people may get angry with you．
You must stop at the traffic lights when they are red． In many countries． it is OK to go past the red lights if you are turning a corner or if there isn't any other traffic around． In the UK you could have a lot of trouble if you do this．
If another driver flashes （闪烁） his cars lights at you， he is probably trying to tell you that he will wait for you to go first． British people don't like to use their car horn （ 喇叭） much and they think people who do so are rude．
If you get in an accident，don't try to pay the police．The police in the UK never take money，and if you try to offer them some， you could end your holiday visiting British prison．
回答下面5个问题，每题答案不超过六个词．
（1）How many tips are mentioned in the passage？
（2）Which side do British people drive on？
（3）If you jump the queue， how will other drivers feel？
（4）What does the driver probably mean if he flashes his car's lights at you？
（5）If you give the police money， what will happen to you？
Athletics vs． Gardening
The students of Southside School were asked to give their opinions about whether the school should run an athletic program or start a vegetable garden．
An athletic program is hatch better than gardening． How are we ever going to win anything at the Inter﹣School Athletics without proper training？ At the moment， we only do athletics for one tam and the teachers train us． We need experts（专家）to teach us things like throwing and high jump． I know lots of kids say they're tot interested in competitions， but that's because they've never won anything． If they got better training and started winning things， they'd soon change their minds． People always say kids don't get enough exercise． Just because you do gardening outdoors doesn't make it exercise， so I don't sec how it matters． Athletics is much better for fitness and lots of kids can have a go at the same tine． I don't think there would be enough jobs for everyone in a garden． In fact， I think a garden is a really bad idea． I don't know why we're even considering it． Liz， Grade 8 |
I think a vegetable garden is a great idea． We already do hours of sport， including athletics． And not everyone likes sport． Gardening is a great way to get exercise without worrying about whether you're any good at it， or whether you're going to win． And you really do gel exercise when you garden． There's digging， weeding and watering Even picking things can be hard work ﹣ pumpkins aren't light you know! There are lots of kids around here who don't have gardens so they can't grow things even they want to． If you really want to do more sport， you can join a club． And think about it： What helps you to be good at sport？ You need to eat lots of fruit and vegetables． If we learn to cook all the things we grow， the garden will keep us all fit and healthy and then we'll be better at sport． Sam， Grade 8 |
（1）Which of these points do Liz and Sam both make？
A． Kids should take exercise．
B． Kids should eat vegetables．
C． Kids should try to win more．
D． Kids should be outside more．
（2）What is one reason Liz gives for saying "a garden is a really bad idea"？
A． Some students don't like getting dirty．
B． Some students don't enjoy being outside．
C． Some students already know how to garden．
D． Some students may have no chance to garden．
（3）Why does Sam say， "And think about it．： what helps you to be good at sport？"
A． To change the subject．
B． To introduce his next reason．
C． To support Liz's idea．
D． To find an answer to the question．
Q： At recess（课间休息）， I don't know what to do because all my friends are playing games I don' like or don't want to play． So I end up standing by myself at recess doing nothing． What should I do？
Alex rider，13， Bloomfield，N．J．
A： In fact， recess was my least favorite part of the school day for Grades 1 to 5． I was never really into playing kickball． So， like you， I spent many days at recess standing alone． Take advantage of the extra time you have．I learned that reading a book is the best way to pass time， especially if it is sunny． Books are good for a lonely recess，because they take you out of your world and into another． If reading isn't your thing， then try making new friends． Some other things I would do at recess were chess and paper cutting． Those might be worth trying． Maybe the teacher who is watching over all the kids needs someone to talk to as well． Whatever you want to do， don't let your time go to waste．Johnny Hayes， 15 |
A： Do you believe in time travel， Alex？Because you just dragged me 40 years into the past． When I was 13， half my friends threw themselves into kickball at recess﹣ which was too vigorous（剧烈的） for me right after lunch． So， like you， I stood around a lot． Then， one day， my teacher， Susie， asked me．"What do you want to do？ I had no answer for her． But suddenly， it came to me： marbles! I asked a few friends， and they were happy to join me． Now， I'm not suggesting you play marbles， only that you consider what you feel like doing and can make you happy． And one last idea： There's no harm in trying games your friends are playing that you think you won't like． You might just surprise yourself． Philip Galanes， adult |

You think it's " cool " to carry your backpacks and head out to school．But if you don' t know exactly how to choose，load，lift and wear them﹣these all﹣important accessories（配件）can be a pain in the back．Not to mention the neck，head and shoulders．
Backpacks can influence your health．Carrying a heavy load improperly can lead to
poor body position；and even hurt the spinal column（脊柱）．This can cause muscle strain，headaches，back，neck and arm pain．
For example，if it is carried on one shoulder，a heavy backpack forces the muscles and spine to balance the unequal weight．This may increase the possible back problems later in life．
More than 50 percent of young people suffer back pain by their teenage years．Research shows that this could be mainly caused by improper use of backpacks．
Here's some advice to help you carry backpacks comfortably and safely．
Choose the right backpack．Forget leather（皮革）!
