阅读下面短文，根据要求完成下列各题．
This is such a heart﹣warming piece of news in the cold winter． Some days ago， the temperature was only ﹣6℃ in Kaifeng， Henan． Someone ordered 50 cups of warm porridge（粥） through Meituan App and noted " Please give the porridge to those sanitation（环卫） workers who are clearing snow on the road nearby and those delivery（递送） men who are delivering food． "When the porridge shop owner received the order， he was moved by the note and provided 60 cups．
The story didn′t end here． As soon as the food delivery man got the big order，he shared it with his workmates so that they could also get paid． Finally， Meituan returned the money to the porridge buyer， Mr． Zhang and gave him a reward of ¥500． Although he had to raise his newly﹣ born baby and pay for his
house every month， Mr． Zhang said he would surely continue delivering love．
The kind help also encouraged many other citizens in Kaifeng．This summer，volunteers are sending cool drinks everyday．
Similar stories have happened in many other places in China． Outdoor workers in different cities are able to enjoy free and caring help． Lots of "love posts"are providing "coolness"in hot summer and"warmth"in cold winter． Just as a citizen of Kaifeng said，"I feel deeply moved and warm in heart．"
In fact， we get love and give love every day． Love delivery makes our life better and more beautiful．
根据上面短文的内容回答问题（每个小题答案不超过6个单词）
（1）What did Mr． Zhang order through Meituan App？
（2）How many cups of porridge did the shop owner provide？
（3）What did the delivery man do when he got the big order？
（4）Was Mr． Zhang rich？
（5）How do you feel after reading this passage？
Summer is finally here for most of us． Sadly， summer is not so pleasant to people in a bit less lucky places， where air conditioning（空调） is not easy to get for most of them．
But as a saying goes， where there is a will， there is a way， especially for those who like doing it
yourself（DIY）． A young man from Bangladesh（孟加拉国） designed an air conditioning system called the Eco Cooler， one that does not require power， and is made of the world's most common waste﹣plastic bottles．
The Eco Cooler is super simple to build﹣no special engineering skills are required． First， to fix it，
a window should be taken away and replaced（替代） by it． Second， a board should be cut into the size of a window． Some bottle﹣neck sized holes should then be cut onto the board． Then， the funnel﹣shaped（漏斗状） bottlenecks， cut from the plastic bottles， should be put into the holes．The next step is to fix the design onto the window frame（框） with the wider side facing outwards． And this is it．
The Eco Cooler then works by catching the winds and sending them inside the building． It can reduce the temperature of a room by as much as 5°C﹣a big difference when looking at comfortable 25°C compared to uncomfortable 30°C．
The idea of the inventor， Ashis Paul， was to show his great product to as many People as possible． For this purpose， he received help from some groups of volunteers． Together， they offered to help local people build and fix the units，as well as teach them how to make them themselves．
Yes， the Eco Cooler is not a super high﹣tech air conditioning system， but it is one that can make a
big difference．
（1）When building the Eco Cooler， we should pay special attention to ．
A． the shape of the window
B． the direction of bottlenecks
C． the temperature of the outside
D． the weight of the board
（2）What can we learn from the passage？
A． Ashis Paul is a clever inventor and a successful businessman．
B． An Eco Cooler can fix the room temperature to comfortable 25°C．
C． The new invention of Eco Cooler is friendly to the environment．
D． Local people will replace their air conditioner with an Eco Cooler．
（3）What's the best title of this passage？
A． DIY air conditioning made from plastic bottles
B． Eco Cooler﹣﹣a super high﹣tech air conditioner
C． Why do we need an Eco Cooler in summer？
D． A strong﹣willed inventor and his DIY dream
Lots of students know what a marathon （马拉松赛跑） is， but perhaps they don't know what a triathlon is． The triathlon is a sport that has three parts ﹣ swimming， bicycling and running． It is not an easy sport， but a man named Joe Salter is very good at it． A few months ago， he finished a special triathlon ﹣ he juggled （抛起接住） three balls all the time during the triathlon． That is to say， he kept on throwing and catching three balls while he was swimming， riding a bicycle and running．

On May 1，a wildfire started in a forest near the Alberta town of Fort McMurray in Canada．Within two days，the fire grew larger and the people who lived in Fort McMurray had to leave their homes．While there have been very few people injured （伤害））by the large fire itself，it has been harmful to the community．
Canadians in other places have been helping by sending money and donations to the Red Cross．Many people in Alberta have taken in people from Fort McMurray，letting them stay in their homes for free until the fire is put out．Many firefighters are needed to fight the fire and some of them have come from other parts of Canada to help．The brave firefighters were able to save 25，000homes as well as the hospital and all of the town's schools，according to CBC news．
There have been thousands of other acts of kindness towards the people of Fort McMurray．Some musicians，such as Great Big Sea's Alan Doyle，are holding special concerts，with the money going to Fort McMurray people．And companies have been helping，as well．Beer﹣maker Labatt filled thousands of cans with water﹣instead of beer﹣and sent them to the people in Fort McMurray．
The fire is huge，spreading over more than 229，000hectares （公顷），but firefighters say they believe they are starting to get it under control﹣it is becoming smaller instead of spreading．
18．How many people have been injured by the large fire itself？

In the future， people may travel to Mars （火星） by water﹣powered spaceship! Today's spaceships are fine for getting things into space， but they are not so good at travelling long distances． These spaceships burn chemical fuels （燃料）， and they are very expensive． Scientists say that a water﹣powered spaceship could make the trip to Mars much cheaper． The idea is just in the planning stages now， but scientists think such a spaceship could be developed soon．
The key to the water﹣powered spaceship is the engine （发动机）． Regular engines push spaceships by burning fuel． The water engine will use steam， created by solar panels （太阳能板） that heat water to a high temperature． Of course， the spaceship will have to carry a lot of water for the long trip to Mars． Today's spaceships could not carry that much water．But scientists think that a spaceship blown up like a balloon will be able to．
One US company has already developed a spaceship like this． These spaceships are made of a strong material． Two of them have already been sent up into space， using rockets and then later filled with air．"Balloon" spaceships could be very large and carry enough water for a long trip． With the "Balloon" spaceships， enough water could be carried to power the engines and grow food during the trip． And the people on the spaceship might even get to take a hot bath!
Scientists say the biggest advantage of such a spaceship would be cost． The "Balloon" spaceship uses water to push it through space and costs about one thirtieth of a normal spaceship． Such savings naturally encourage continued research into balloon spaceships and w after engines． If these scientists are correct， we may soon be on our way to Mars in a spaceship powered by water．
（1）Which sentence best describes the main idea of the passage above？
A． The key to the water﹣powered spaceship is the engine．
B． In the future， people may travel to Mars by water powered spaceship．
C． One US company has already developed a spaceship like this．

C． Blow up a balloon．
D． Change the surface of Mars．
（4）On which website can we probably read this passage？

Robots Are Now Teaching English!
Get ready． Robots are about to invade our classroom． From Korea to Japan to the United States， schools are putting English﹣speaking robots in front of their students． In Korea， robots are the new teaching assistants in a number of preschools and kindergartens． The young students say that the robots are fun， but are these children really learning anything？
I don't think a computer will ever be able to do what a teacher does． A teacher has to be able to respond to students as individuals （个体）．__▲__and a teacher has to change his or her teaching style to fit the needs of the student． I seriously doubt that a computer will ever be able to do this even though the big data （数据）is widely used in the world．
4 Comments on "Robots Are Now Teaching English!"
Sara says：
In my opinion， schools should spend money training human teachers rather than buying robots． Research shows that children learn more from real speakers than from recorded conversations．
Keiko says：
I don't think you can learn a language without real human interaction．After all， robots cannot think as humans do．
Hassan says：
Robots might be able to help people lean a language， but I don't think they should replace teachers because robots are just machines without human feelings．
Nancy says：
I think robots might be very helpful in the classroom． A child might be less afraid to make a mistake in front of a robot than in front of a real person．

We touch our faces all the time， and it had never seemed to be a big problem ﹣ until COVID 19 arrived．Touching our faces ﹣ the "T﹣zone' 'of our eye， nose and mouth ﹣ can mean giving ourselves this virus．
This is why some organizations have suggested that we should avoid touching our faces．William Sawyer， from Henry the Hand． told The Washington Post， "Just stop this simple behavior，and that would be better than any vaccine （疫苗）lever created，"
However， stopping this "simple" behavior might he harder than you think because we are used to it．
Some face﹣touching is an automatic reaction： like when there is an itch （痒） on your nose，you'll touch it again and again without thinking． A 2014 study found that touching your face also helps you to have less stress．For example． it's possible for you to do it when you feel embarrassed．According to Dacher Kelmer， a psychologist an the University of Califormia Berkeley， Us． this action may also have a social use： When you are taking to someone， for example， touching your face means you want to talk about another thing．
Besides， it's very hard to change this face touching "because you don't even kn6w you're doing it"，said Sawyer．
But you're not alone． In a 2015 study． it was found that a group of medical students touched their faces about 23 times an hour ﹣ with 44 percent of the touches in the T﹣zones" ， That was very surprising because medical students should know better．
Since it's so hard to shake the habit， maybe the easiest way is to wash our hands more often．This way， we can be sure that our hands are safe from COVID﹣19．
（1）The "T﹣zone" is formed from ．
A． Our eyes
B． our nose and mouth
C． our eyes， nose and mouth
（2）In the second paragraph， Sawyer thinks that ．
A． face﹣touching is simple and helpful
B． we should avoid touching our faces
C． face﹣touching may be better than vaccine
（3）Dacher Kelmer believes that ．
A． face touching may increase stress
B． face﹣ touching may have a social use
C． face﹣touching may cause an itch on your face
（4）The last paragraph tells us to ．
A．wash our hands more often
B． stop the habit of touching our faces
C． ask medical students not to touch their faces
（5）What is the main idea of the passage？
A． face﹣touching may give us COVID﹣ 19．
B． Face﹣touching may be very useful for us．
C． Stopping face touching might be harder than we think．

There are plenty of myths（神话） to explain how the world came to have a moon to bring light to the night time． But now there is a plan for a man﹣made moon． It will give us much more light than the natural Moon．
China is preparing to put a man﹣made moon in the sky above Chengdu by the end of 2020．It will reflect sunlight back onto the Earth． If it succeeds， three more such objects will be sent out in 2022，according to Wu Chunfeng， a space scientist． Wu said it would be similar to how we get moonlight， but he predicted（预言） that the man﹣made moon would have eight times the brightness of the real one．
This is because the object will be about 500 kilometers above the Earth． That will make it much closer to us than the moon， which is over 380 ，000 kilometers away，Wu added．
If the plan works， the man﹣made moon will save a lot of power．Scientist predicted that Chengdu could save around 1.2 billion yuan in electricity every year if a new moon lit up 50 square kilometers of the city．And in 2022 ， four man﹣made moons can take turns reflecting sunlight as they will not always be in the best position relative to the Sun． Together， they can give light to an area of up to 6 ，400 square kilometers on the Earth for 24 hours．That means its brightness will be seen in most areas in China，so reducing the need for streetlights．

Texting while driving is against the law in 47 states． But what about texting while walking？ A 2018 study reported that more than 2， 500 people in the US ended up in hospitals resulting from using a mobile device（设备） while walking．
Hawaii passed a law making it illegal（违法的） to text or look down at a mobile device while crossing the street． It is the first state with a law like this． Do people think more places should accept such a law？ The LA Times did a survey． Here are some replies they received．
Rena Jose， 2， New York Which is more important， texting or safety？ If you are looking at your phone while walking， you might not see a car come or traffic lights turn red． It can be very dangerous． For example， in Japan， one person fell into a lake and another got her leg stuck in a hole， because both had their mind on their phone． We should make texting while crossing the street illegal in more cities． |
Andy Selvam， 55， California People do many things that cause injury to themselves but are not illegal， such as climbing mountains， driving cars， swimming and so on． People might get hurt from texting and walking if they're not paying attention． But I still think they should have a choice． |
Bob Madigan， 45， Oregon As humans， we can make our own decisions． I'm not saying it's safe， but we don't need the government to babysit us． If we want to learn to make smart decisions， the government needs to stop telling us what to do． After all， this is a free country． |

"Made in China" is having its moment now﹣and it's a fashionable one．
The story of Chinese fashion began in 2011 when Feiyue and Huili， both Chinese sports shoe brands（品牌）， suddenly got international attention． Their products were seen all over the world． Chinese sportswear brand Li Ning was at the New York Fashion Week in September， 2018． They showed their new designs﹣sweaters and jackets with Chinese characters．
Shaun Rein， managing director of China Market Research Group， said that the latest Chinese brands no longer catch customers' eye by low price． He told CNN， " They are sure that they can go head to head with foreign brands．
