If you want to be a citizen scientist,the National Science Foundation(NSF) has got you covered.NSF supports citizen scientists across all areas of science,whether your passion（热情）is scanning the night sky,exploring your own backyard or playing video games. Join a Flock of Birders eBird is an online platform that allows bird-watchers to record their sightings on a massive online database. With more than 100,000 active users,eBird involves bird population,distribution（分布）and habitat that users can explore in real time.In May 2015,there were 9.5 million records uploaded. Count Every Drop The Community Collaborative Rain and Snow Network is the largest provider of daily rainfall observations in the United States.Volunteers set up rain instruments and record data every time a rain,or snow storm passes.Data is organized and shared on the CoCoRaHS website,and used by the National Weather Service,scientists,farmers and so on. Join the Plankton Party Without plankton（浮游生物）,life in the ocean would not exist.These tiny things form the base of the food chain and play an important role in the global carbon cycle.Plankton Party encourages citizen scientists to identify images snapped（拍照）by the ISIIS,an underwater robot.Classifying the images helps researchers understand plankton diversity,habitat and behavior. 21.What can bird-watchers do with eBird? A.Watch birds through satellites. B.Choose their favorite birds. C.Upload their sightings to a database. D.Observe the night sky 22.Which subject can you learn about if you join Count Every Drop?

Your next car might drive itself.After years of trials on city streets,driverless vehicles are now on the way.Last month,a driverless bus began carrying passengers through Lyon,France.Most in the automobile industry think self-driving vehicles will be on the road by 2020 or earlier. Driverless cars will first be huddled with human-driven cars.But the first places where they will become dominant（统治的）are highly populated urban areas.Many advanced cities are already reducing the role of human-driven cars.Driverless cars will quicken that process and will bring us enormous benefits. Driverless cars will reduce accidents by around 90 percent.That's big—the annual deaths on the world's roads are about 1.2 million a year.Pollution and carbon emissions will drop,because urban driverless cars will be electric. On the other hand,driverless cars will cause problems.Over the next 20 years,the mostly low-skilled men who now drive trucks,taxis and buses will see their jobs reduced.Traditional carmakers are especially scared.The cars of the future might be made by tech companies such as Apple,Baidu and Google.Imagine Germany,where automobile making is the largest industry. Dramatic changes are coming,and driverless cars could arrive by 2020.But governments have barely begun thinking about it.Only 6 percent of the biggest US cities have taken them into their long-term planning.A decade ago anyone hardly saw the Smartphone coming.Now what about the driverless cars? 24.The underlined phrase "be huddled with" in Paragraph 2 is closest in meaning with " ". A.turn up B.make up for C.exist together D.take over 25.Driverless cars can reduce pollution and carbon emissions because . A.they will reduce the number of cars B.they will be powered by electricity C.they will be energy-saving by driving themselves D.they will avoid many accidents from human errors 26.What's the author's attitude toward driverless cars? A.Doubtful. B.Disappointed. C.Negative. D.Objective. 27.What can we conclude from the passage? A.Driverless cars will not hit the road until 2020. B.Old auto industry will benefit from driverless cars. C.Governments are unprepared for the arrival of driverless cars. D.Driverless cars will make road accidents a past thing.

When Bonfield,the chief of the Women's Engineering Society,recently attended a military air show,she was in great shock. There were around 900 girls among the crowd and Ms Bonfield said,"I'm saying to all these girls,'Do you know about engineering?Would you like to be an engineer?Have you thought about engineering?'And in the whole day... probably five or six of them said yes.Every other one said no,just straight out no." What surprised her most wasn't that these girls didn't know what engineering was.It was simply that they had already switched off.They had lost interest in engineering."So how much work does it take to change that?"asked Ms Bonfield,"I mean it's huge." There's no shortage of data to back up her ideas.The latest figures from the Office for National Statistics show that women make up around just 8% of engineers in the UK.And this is at a time when the UK needs to produce thousands more engineers,so much that the inventor,Sir James Dyson,is planning to open his own institute to deal with the skills shortage. One of the reasons why girls don't choose engineering is that there are not enough female role models.The attitude of parents is also an important factor in career choices.For girls,perhaps unsurprisingly,mothers are particularly influential. "My mum was a bit uncertain about it at first,"said middle school student Hannah,"But my dad used to build a lot of stuff and he got me into that.So after my mum saw how me and my dad interacted,she said,'Yeah,go for it' and she's kind of the one who supported me with this." 28.What greatly surprised Bonfield at the military air show? A.So many girls came for the air show. B.Quite a few girls had interest in engineering. C.Girls were not interested in the air show. D.Girls had shut their door to engineering. 29.Sir James Dyson hopes to set up his own institute to . A.invent more new things B.handle the shortage of engineers C.allow more girls to receive higher education D.create more jobs for girls 30.What made Hannh finally choose engineering? A.Her mother's encouragement. B.The demand of society for engineers. C.Her father's positive influence on her. D.Her born interest in engineering. 31.What is the author's purpose of writing the passage? A.To explain what causes the shortage of girl engineers. B.To introduce some famous girl engineers to readers. C.To promote the social status of female engineers. D.To give girls advice on how to choose future careers.

A simple gesture can be formed into a child's memory so quickly that it will cause the child to give a false answer to a question accompanied by that gesture.A new finding suggests that parents,social workers,psychologists and lawyers should be careful with their hands as well as their words. While memories of both adults and children are easy to react to suggestion,those of children are known to be particularly influenced,said a researcher,Sara Broaders of Northwestern University. Previous research,for example,has shown that detailed questions often cause false answers;when asked,say "Did you drink juice at the picnic?",the child is likely to say "yes" even if no juice had been available.It is not that the child is consciously lying,but rather the detail is quickly formed into his or her memory. To avoid this problem,social workers have long been advised to ask children only open-ended questions,such as "What did you have at the picnic?"But an open-ended question paired with a gesture,is treated like a detailed question.That is,children become likely to answer falsely. And 77% of children gave at least one piece of false information when a detail was suggested by an ordinary gesture.Gestures may also become more popular when talking with non-fluent language users,such as little kids. Broaders advises parents and other adults to "try to be aware of your hands when questioning a child about an event. Otherwise,you might be getting answers that don't mean what actually happened." 32.According to the author,gestures . A.have not any function at all B.are rarely used by people C.have a certain effect on children D.are often used by social workers 33.In Sara Broaders' view, kids are easy to be misled by gestures just because . A.these gestures are very attractive B.their memories are affected easily C.children are easy to tell lies D.they like these gestures 34.According to the text,which of the following questions may cause a wrong reply? A.What will you have for lunch? B.Did you cheat in the last English examination? C.Where are you going,Lucy? D.Did you see anything else last night? 35.When talking with little kids,adults are supposed to . A.ask less open-ended questions B.use familiar words and phrases C.ask detailed questions D.use gestures carefully
