Over the years, NASA has successfully sent several rovers (飞行器) to Mars. While the science laboratories continue to provide important information on the Red Planet, they keep the space exploration rovers staying closeto the original landing place.To get a more comprehensive (详尽的) view of Mars, the US Space Agency plans to make a small test helicopter with the Mars 2020 Rover, which will be sent off in July 2020.
The football-sized “marscopter” weighs about four pounds.It can fly at about ten times the speed of helicopters on Earth. The light weight and fast speed are important for the helicopter to be able to fly in the thin Mars atmosphere, which is about just one percent of that of Earth. “To make it fly in that thin Mars atmosphere, we had to make everything ready, and make it as light as possible while being as strong and powerful as it can
possibly be. “Mimi Aung, Mars helicopter project manager, said in a meeting.
Upon landing on the Red Planet, the Mars 2020 Rover will find a proper location to send of the helicopter. The helicopter will start with a short climb, no higher than 10 feet, and hover (盘旋) for just 30 seconds before landing back on the Mars surface. If all goes well, five more flights of longer distances, for 90 seconds each, will be conducted over the next 30 days. The short journeys will be recorded by a small camera and sent back to the scientists on Earth.
If the plan goes on well, the first helicopter to fly in another world, will open up a whole new way to explore Mars. The Mars helicopter's first flight will be a great invention. For those of us whose research is about flight, that would be a wonderful, historic moment.
4. To fly in thin Mars atmosphere，we should make the helicopter_______.
A. strong and heavy
B. heavy and fast
C. light and fast
D. strong and slow
5. How many times will the helicopter fly?

7. What may be the best title for the passage?

B. To send a rover to Mars in 2020
C. To live in the thin Mars atmosphere
D. To send back records to scientists

As an eco-minimalist, Su Yige has maintained an environmentally friendly and sustainable lifestyle for the past three years while studying in Canada. She takes her own bag when she goes grocery shopping and uses second-hand items as often as possible. She avoids almost all paper-related products unless she has to use a public toilet while away from home.
Diligence and thrift are time-honored traditional Chinese virtues. Su's family is a good example of this, according to the native of Weihai, Shandong province. Although they have little formal “green” knowledge, her parents lead a very environmentally friendly life.
For example, the family has used the same hair dryer for more than a decade, and Su remembers many of her mother's clothes from as far back as kindergarten. “As long as something can still be used, my mother will not replace it with a new item,” she said.
“I frequently asked my father to bring the plastic bag back home after dumping our waste in the trash bin. He was unhappy, and argued that instead of making that request, I should go downstairs to dump the waste myself” she said. In another move, her father criticized her for doing too much shopping online. Eventually, they both made steps toward becoming better environmentalists. Her father brings the bag back for reuse and she has only bought two pieces of clothing online in the past six months.
Back in Canada, Su is looking forward to finding a job related to sustainable development in China after she graduates as a computer science major in the summer.
8. Which of the following best describes Su Yige?
A. Conservative.
B. Nostalgic.
C. Economical.
D. Productive.
9. What can be found about Su's mother according to the third paragraph?
A. She has a lot of formal green knowledge.
B. She regards using the same items as a lifestyle.
C. She always wears old clothes due to lack of money.
D. She will not replace the old items until they are out of style.
10. What can be inferred about Su and her father?
A. Both of them like to criticize each other.
B. Su's father is particular about her clothes.
C. The relationship between them is very tense.
D. They urge each other to become more environmentally friendly.
11. What can we learn about the author soon after she graduates in Canada?
A. She will stay there to look for a job.
B. She will put effort into computer science.
C. She will devote herself to her motherland's future.
D. She will come back to China to stay with her parents.
D
Kenyan mother Beth Mwende heard her sleeping child cry out, but did not worry after the three-year-old quickly quietened down. The next morning, however, she found her daughter, Mercy, nearly unconscious with two
bite marks in the neck. “I didn’t know that it was a snake,” Mwende said.
Although snakebites are common in her hometown, antivenom medication is difficult to get. Mwende lives about 160 kilometers east of Nairobi, Kenya’s capital. So she took her daughter to a traditional healer. He placed stones over the bites. Mercy died within hours. She was one of about 700 Kenyans killed by snakebites each year, notes a report in the scientific publicationToxicon.
The Kenya Snakebite Research and Intervention Center (KSRIC) is working to change that. The KSRIC hopes to have East Africa’s first antivenom medication on the market within five years. It estimates the cost will be about 30 percent of an imported product, which often sells for about US $ 30.
More than 70, 000 people are bitten in East Africa each year. Climate change and deforestation are worsening the problem as snakes get pushed out of natural surroundings into populated areas.
Nearly 100 snakes live at the research center in a forest near Nairobi. Researchers take venom from snakes and study it before injecting small amounts into other animals, such as sheep. The animals then create antibodies that can be made into antivenom.
“Up to now, no one has made any kind of antivenom in Kenya,’’ said Geoffrey Maranga Kepha, a senior snake handler.
Two effective antivenoms are available in Kenya, from India and Mexico, the center says.
The center is teaching communities that using antivenom immediately after receiving a snakebite can save lives, said head researcher George Adinoh.
“After seeing how people died in Kenya from snakebites I decided to devote my life to coming up with a rescue measure that will help or prevent people from dying from snakebites,” snake handler Kepha added.
12. How does the author introduce the topic of the text?
A. By telling a story.
B. By listing figures.
C. By referririg to documents.
D. By making a comparison.
13. Why did Mwende take her daughter to a traditional healer?
A. She couldn’t afford any modern treatment.
B. She lived where antivenom medication is not available.
C. The traditional way is very effective to treat snakebites.
D. She believed a traditional healer could cure her daughter.
14. What is causing more snakebites to happen in East Africa?
A. Lack of antivenom medication.
B. Environmental damage and climate change.
C. People’s low awareness of the danger of snakes.
D. People’s pursuit of traditional cures for snakebites.
15. What do we know about antivenom in Kenya from the text?
A. Itis taken from antibodies of sheep.
B. There is only one effective antivenom available.
C. KSRIC is trying to develop a local antivenom now.
D. People refuse to use antivenom after being bitten by snakes.
