British chemist David Evans has become an overnight celebrity on Chinese social media.His chemistry experiments have attracted over 2 million followers in just a few months.Evans is a chemistry professor at the Beijing University of Chemical Technology.The 60－year－old always wears a white lab coat, a pair of safety goggles (护目镜), and smiles often.Some web users say he looks just like the “grandpa of KFC”．
Evans has posted videos of various experiments.His most popular experiments have attracted millions of hits on video－sharing apps.Excited children's cheers and shouts can be heard in his videos.“I hope my experiments can arouse people's interest in science，” he says.
Evans has been interested in China since childhood.In the early 1970s, before the reform and opening－up, he viewed it as a “country full of mysteries”．He first visited China in 1987 to attend a chemistry conference in Nanjing, Jiangsu Province.He quit his job in the United Kingdom and moved to Beijing in 1996.Many of his friends thought he was crazy.But Evans says they just saw China's challenges but not its potential.
Since 2011, Evans has turned to the Internet to popularize science.He learned short－video apps are also popular in small cities and rural areas.And he realized this enables him to reach more students, who lack opportunities to perform fun experiments.But even a one－minute video requires a considerable amount of work.Still, he thinks it's worth it to fulfill his responsibility to popularize science.
His experiments always fill schools' lecture halls with laughter.Some viewers call him “a Harry Potter－like magician”， but he disagrees.“A magician never tells the secrets behind his tricks, but a scientist always gives an explanation.” He sees himself as a teacher.He performs experiments to spread knowledge, inspire thinking, remove misunderstandings and show that science can create changes.Evans says he looks forward to more “chemical reactions” with China.
4．Who is David Evans according to the passage

Andrew Grey doesn't fit most people's idea of an astronomer.He works in a car repair shop, not in a lab or university, yet the Australian repairman discovered a star system hiding in data from NASA's Kepler space telescope.
Mr Grey is one of millions of citizen scientists helping researchers to expand collective understanding.For centuries, only a few ordinary people had been contributing to science, but advances in technology have brought a higher level of democratization (民主化) to science.
“This is a collaborative (合作的) effort that anyone could get involved in，” says Chris Lintott, an Oxford University astrophysicist (天体物理学家) and co－founder of Zooniverse, a platform that hosts dozens of citizen science projects.Citizen scientists can contribute to breakthroughs in almost any field, from ecology to astrophysics.
“As long as pattern recognition is involved, there are no limits to what can become a citizen science project，” Lintott says.“Anyone can identify patterns in images, graphs, or even seemingly boring data after a short tutorial.Machine learning allows computers to do some pattern recognition.But humans, particularly amateur scientists, don't stay focused on what they're supposed to.And that's good, because people who do that notice the unusual things in a data set.”
“And citizen science doesn't have to be directed by a scientist，” says Sheila Jasanoff, director of the Program on Science, Technology and Society at Harvard University.“Citizens producing knowledge in places where official organs have failed them can also be citizen scientists，” she says.That's what happened in Flint, Michigan, when a local mother started drinking water tests that caused a broader investigation of lead levels.
Citizen－powered research is as old as scientific inquiry.For centuries before science became professionalized, regular people looked for patterns in the world around them.Despite a lot of advanced equipment and computer models, scientists still welcome help from everyday people.
As a professional scientist himself, Lintott says, “People think that we're intelligent, but science is easy and we need your help.”
8．What made citizen scientists appear
A．The high level of science projects.
B．The development of technology.
C．The support of the government.
D．The foundation of Zooniverse.
9．What is an advantage of humans in pattern recognition compared with machines
A．Humans can identify patterns more swiftly.
B．Humans focus their attention on data.
C．Humans can observe uncommon things.
D．Humans have stronger emotions.
10．What is Lintott's attitude towards citizen science
A．Favorable.　　　　　　 B．Cautious.
C．Indifferent. D．Doubtful.
11．What would be the best title of the text
A．Citizen scientists can be intelligent
B．Science is important to everyone
C．Anyone can be a scientist
D．Science is everywhere
D
We live in an age when all scientific knowledge — from the safety of vaccines (疫苗) to the reality of climate change — faces organized and often angry opposition.Doubters have declared war on the consensus (共识) of experts.It seems that people have turned argumentative overnight.
In a sense, all this is not surprising.Our lives are affected by science and technology as never before.The world seems full of real and imaginary dangers.Though scientists agree that the Ebola virus is spread only by direct contact with blood or body fluids (液体), if you type “airborne Ebola” into an Internet search engine, you'll find that some people believe that this virus has almost supernatural power.
In this often confusing world, we need to rely on science to decide whether what we choose to believe has a basis in the laws of nature or not.But science doesn't come naturally to most of us.Science has often led us to truths that are really mind－blowing.For example, although the roundness of the Earth has been known for thousands of years, some still feel it hard to accept.
Even when people become scientifically educated, most of them still try to make sense of the world by relying on personal experience, stories or emotions rather than statistics.When they hear a number of cancer cases in a town with a dangerous waste dump (垃圾场), they believe pollution caused the cancers.Yet two things happening together doesn't mean one caused the other.Even when they turn to the Internet, they let in only the information they agree with to strengthen their belief that has already been shaped by their worldview.
How can scientists convince doubters Throwing more facts to people may not be enough.More efforts are supposed to be made.
12．What's the text mainly about
A．How people view the world.
B．What challenges science faces.
C．Whether science is worth respect.
D．Why people show disbelief in science.
13．What does the underlined word “mind－blowing” in paragraph 3 probably mean
A．Unbelievable.　　　　　　　 B．Desirable.
C．Dangerous. D．Obvious.
14．How do “people” in paragraph 4 understand the world
A．They apply logical thinking.
B．They stick to their own belief.
C．They form the views on assumptions.
D．They rely on the information on the Internet.
15．How does the author prove his opinions
A．Through comparison. B．Through quotation.
C．By giving examples. D．By making definitions.

阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。
Around 200 years ago, a well－known English poet called John Keats attacked science.He said that British scientist Isaac Newton had “unweaved (拆解) the rainbow”．Newton explained how light forms a rainbow.For Keats, this explanation meant rainbows could no longer be beautiful.
__16__ We often hear people talk of problems with science, or say that it is boring.Some people, like Keats, also say that science takes away the beauty of the world.But is this fair
First of all, science helps us get things done.__17__ When you are studying science in school, remember that one day you might be using that knowledge to build a bridge, or save a life.Next time you use your phone to send a message, remember that this is possible thanks to science.When Keats criticized Newton, the very paper he wrote on was created through science.Beyond helping society and getting things done, science also makes us think in a certain way.__18__ It teaches us never to trust our assumptions.It teaches us that sometimes, the truth is stranger than fiction.
When you study science, remember what it means.__19__ Humans once looked up at rainbows, and said that they were beautiful.Science explained them, and they were no longer mysterious to us.__20__ Through science, we can find new rainbows: mysteries that lie beyond the stars themselves.
A．But discovery never stops.
B．This is just one example of many.
C．It is a constant search for truth and knowledge.
D．Science is not so closely associated with our lives.
E．It asks us to believe things only through evidence.
F．It helps us understand the world in which we live and how it works.
G．See science as a tool to discover how living things interact and evolve on Earth.

阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
One time，the teachers at a school wanted to teach the students about airplanes.While all airplanes can fly, some are able to fly farther than others.This is because not all airplanes are built the same.For example, a fighter plane looks very different from a plane that people fly in when they want to go on a holiday.The teachers wondered how they could make students understand this.
Then, the science teacher, Mr Moose, decided that the school should have a paper airplane contest.Every student would design a paper airplane.They would stand in a line in the playground behind the school.The students would take turns throwing their airplanes.The student whose airplane went the farthest would win.
When Mr Moose announced the paper airplane contest to the students, they were very excited.A student named Paul, who was on the school sports team, said to everyone else that his airplane would win.“I am the strongest，” Paul said.“So I will be able to throw my airplane the farthest.”
However, while Paul was saying this, another student, Brian, was thinking how he could win.Brian did not play any sports and was not very strong.But he loved airplanes and really wanted to win the contest.
Brian realized what he had to do.He went to the store and bought a big stack (叠) of paper.When he got home, he took the paper into his backyard.He took a piece of paper and folded an airplane.It didn't go very far, so Brian took another piece and folded another airplane and threw it.This airplane went a little farther.Brian kept folding different kinds of airplanes and throwing them.Some went very far and some did not.Finally, when Brian had used all the paper, he walked up to the airplane that had flown the farthest and picked it up.
The next day was the contest.All the students lined up.Everyone took turns.After a while, everyone had thrown except Paul and Brian.Paul went first.With a loud yell, he threw the airplane into the sky.It went farther than every other airplane.Everyone cheered.

参考范文：
Dear Tom，
I am excited to tell you that the first Science and Technology Festival was held in our school last month.It aimed at enriching us students' school life and promoting the students' awareness of innovation.
There were a variety of activities in the festival, which included Makers on Campus, where participants could show their designs and products, and an exhibition of the students' original inventions, designs and literary works. With the enthusiastic participation and support of all the students, the activity turned out a great success. I was astonished at the schoolmates' creativity and teamwork spirits.
I do hope more activities will be held in my school to provide us with chances to practice our critical thinking and problem－solving abilities.
Yours，

第二节
参考范文：
Finally, it was Brian's turn.Brian took the airplane that he had picked up the day before.He walked up to the line and, with all his strength, he threw the plane.It went flying, farther and farther, until finally it landed — 10 feet past Paul's plane! The whole school cheered.Brian won the contest.Mr Moose gave him a prize: a toy airplane.
Brian won because he tried out many solutions to the problem of how to make an airplane fly very far.He did this by testing out many different designs and comparing the results.When he found the design that worked best — the paper airplane that flew the farthest — he used it.Because Brian tried a lot of designs, he was able to make up for his lack of strength and beat Paul.
