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．

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 |

Everyone needs help sometimes． People depend on one another． That's why communities have special people ready to lend a helping hand to anyone who needs it．
For example， what would we do without a community fire station？ If a home catches on fire，as the Jackson place did last week， it might be burned down and people get hurt..or worse． We re so lucky to have firemen to come to save people and put out the fire， safely． If the fire station hadn't come so fast， the Jacksons might have lost everything．
And what about our local police who protect our families， our homes and valuable things？The police have helped so many families this past year，especially saving people and pets and protecting our houses and other things after the heavy rains．
Think about all the other service workers we have in this community． We have people who collect waste and rubbish and keep our community sanitary ．We have road workers who put up and repair traffic signs and fix holes in the streets to protect not just us， but our cars! And where would this community be without the teachers in our school and the doctors， and nurses in our community hospitals？
Think again about what we eat every day； think again about what we wear every day． We cannot produce them， but we use them all the time． We get a lot from all these tireless workers who keep our community running． We need these people in the community． We depend on each other． Let's support each other and help each other． Only in this way can we make our community a better place．

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）! It looks great，but it's far too heavy．Go for canvas（帆布）．Pick a pack that has two wide，adjustable，comfortable shoulder straps（带子），along with a hip or waist strap，and plenty of pockets．Make sure the pack fits properly and its size is suitable for the wearers body．
Packing it properly．Only put in the pack what is needed for that day．It's a good idea to know what each object weighs．The total weight of the filled pack should be no more than 10 to 15 percent of the wearer's own body weight．Pack heaviest objects close to the body，and place little ones outside， away from the back．
Putting the backpack on．Put the pack on a smooth surface，at waist height．Put on the pack，one shoulder at a time，then adjust（调整）the straps to fit comfortably．Remember when lifting a backpack， or anything，to lift using the arms and legs and to bend at the knee．
The right way to wear a backpack，Both shoulder straps should be used，and adjusted so that the pack fits the body，without hanging to one side．Backpacks should never be worn over just one shoulder．You should be able to move your hands between the backpack and your back．The waist strap should also be worn．
Take the above advice，and you may not complain back pain，numbness or weakness in your arms and legs any more．

Drones（无人机）are like planes， but come in many shapes and sizes． They have no pilots and controlled from outside the drones． During these years， they have been used to attack（进攻）enemies or move goods in dangerous areas．
Now small drones are a part of people's lives． For example， people use drones to take photos or make videos． Besides， a drone delivery （投递） service has proved successful．
Online store JD can use drones to deliver small packages（包裹）． It has built several drone stations so that it can load （ 装载） and deliver its packages．
Drones have made our shopping experience different． We can order a new coat in early morning and it will be delivered before we finish breakfast．
Bizzby Sky， a UK company， has created a delivery service for small goods． Open a smartphone app（应用软件） ，enter your address， set a time and pay enough money for the delivery service． Then in minutes， a drone will do tasks for you．
However， any drone company needs government permission （允许） to fly its drones in many countries． We believe we will see more and more drones with goods fly in the sky very soon．

"Volunteering makes you look at the world differently． You see how little things can change a person's life for the better， which makes everyone a better person．" Mason， a volunteer said．
National Volunteer Week started in 1974 and is held every April． It is a time to thank volunteers for their achievements． It is also a perfect opportunity （机会） to encourage others to take their first step toward becoming a volunteer． Making the decision to take the first step can be the biggest problem， because they often wonder if they will be able to meet the organization's expectations （期望）． Some people fear not knowing anyone else in the group． Not having enough time also prevents some from sharing their abilities．

As Internet users become more dependent on the Internet to store information，do people remember less？if you know your computer will store information，why do you store it in your own personal memory，your brain？Experts are wondering if the Internet is changing what we remember and how.
In a recent study，Professor Betsy Sparrow made some experiments（实验）.She and her research team wanted to know how the Internet is changing memory.
In the first experiment，they asked two groups of people to put 40 unimportant facts into a computer.The first group of people understood that the computer would store the information.The second group understood that the computer would not store it.Later，the second group remembered the information better.People in the first group knew they could find the information again，so they did not try to remember it.
In the second experiment，the researchers gave people facts to remember，and told them where to find the information on the Internet.The information was in an exact in an exact computer folder（文件夹）.Surprisingly，people later remember where the folder is better than the facts.When people use the Internet，they do not remember the information.However，they remember how to find it.This is called "transitive memory （交互记忆）".
According to Sparrow，we are not becoming people with poor memories as a result of the Internet.Instead，computer users are developing stronger transitive memories；that is，people are learning how to organize a lot of information so that they are able to get it at a later date.This doesn't mean we are becoming either more or less clever，but there is no doubt that the way we use memory is changing.

（2）What can we learn form the first experiment？
A.Sparrow put the information into the computer.
B.Both groups remember the information well.
C.Group 1 remembered the information faster.
D.Group 2 remembered the information better.
（3）What do we know about transitive memory from the second experiment？
A.People organize the information like a computer.
B.People remember how to find the information.
C.People remember how to make a folder.
D.People keep the information in mind.
（4）What's Professor Betsy Sparrow's conclusion（结论）？
A.People become more and more clever.
B.The way people use memory is changing.
C.The way people make experiments is changing.
D.People's memories become poorer than before.
What would you do if you had trouble seeing clearly？You would probably go to an eye doctor who might give you glasses.For many people around the world，however，such a way isn't that simple.
The World Health Organization reports that glasses can help one billion people in the world.Yet places like Ghana have only one eye doctor every 8 million people. Thismakes glasses almost impossible to get.Joshua Silver，a teacher at Oxford University，however，may have solved the problem.
Mr.Silver has developed liquid（液体）﹣filled glasses that users can adjust（调整） by themselves without seeing a doctor!The lenses（镜片） are filled with oil.Using a dial on the glasses，the user changes the amount of oil.This changes the strength（度数） of the lens.After the user finds the right strength，he then fixes the lens.
Results show that among those who have tried the glasses，around 80% are satisfied.Mr.Silver's goal is for everyone who still needs glasses to have such glasses as soon as possible.With a little more effort，Mr.Silver thinks that his goal might be achieved in the near future.

Have you ever counted the number of digits （数字）in your mobile phone number？ Your number has 11 digits． You may sometimes find it hard to remember your number． That's because China has the longest mobile phone numbers in the world． Why is that？
The 11 digits can be divided into three parts． Each part has a different meaning． The first three numbers tell you which mobile phone service provider（提供者） you are using． For example， 135 is for China Mobile Communications Corporation and 188 is for China Unicom． The fourth to the seventh digits tell you where the number is registered （注册）． And the last four digits are random（随机的）．
The main reason for using 11 digits is that we have the largest population in the world． We once had 10numbers． But as our population grew， there were not enough numbers for us to use． So we began to use 11 digits starting from 1999． Eleven digits can be used to make tens of billions of mobile phone numbers． That's enough for each person to have seven or eight phone numbers to use in China．
And mobile phone numbers can be recycled． Usually， the service provider will reuse a canceled number after three to six months． If you call a number that you haven't contacted （联系）for a long time， you may find that its owner has changed．
Besides China， Britain and Japan also use 11﹣digit mobile phone numbers． But their numbers always start with 0． So they cannot create as many numbers as we can． Countries like the United States， Australia and India use phone numbers with 10digits． Canada's mobile phone numbers are perhaps the shortest in the world： they use seven digits．
