2017年中考英語模擬真題及答案(2)
D
S cientists have found that migrating (遷徙) birds fly not just in groups all the time, but in “V” formation and they have also tried to find out what good points birds get from this “V” formation. Now, a research group from the University of London may have found the answer – migrating birds fly in a “V” to save energy, according to a study published in the journal Nature.
When a bird flaps (拍打 ) its wings, it makes the air move in different directions. Scientists found in the study that the air creates an upward-moving wave at the tips of the wings (翼尖), which means that if a bird flies around the wingtips of another bird, it can get some help from the rising air and then they can use less energy to stay in the air.
But there is a small problem – the lead bird gets no lift advantage and can easily get tired. This is why a group of migrating birds change their leaders from time to time, according to The New York Times.
Scientists were also surprised to see that migrating birds timed their wing beats and changed their places in a very simple way to make the most of the lifting effect while avoiding areas where the air moved downward.
“They’re able to sense what’s going on from the bird in front, where this ‘good air’ is coming from and how to help themselves perfectly in it,” lead researcher Steven Portugal told BBC.
In fact, the “V” formation has long been thought to help birds fly more efficiently (有效地) without wasting too much energy. Jet fighters (戰(zhàn)斗機(jī)) were also found to be able to reduce their energy use by up to 18% by staying near the wingtips of other Jet fighters. Both of these findings led scientists to wonder that the “V” formation had an efficiency purpose, but until now they still don’t have enough facts to show what they are thinking about is really true.
“For scientists, the new study provides an insight into an interesting natural thing. But it could mean even more for airplane companies – helping them understand how they can imitate that with their plane formations to save energy,” said Portugal.
55. According to the new study, when birds migrate, ______.
A. they don’t often change their lead birds
B. they fly in “V” formation to make best use of lift
C. they fly in “V” formation to protect the birds behind
D. the air around them makes it hard for the lead bird to fly fast
56. What is the importance of t he new study according to the article?
A. It suggests that the “V” formation can help planes fly faster.
B. It has led scientists to study more about different kinds of birds.
C. It might help airplane companies to think of ways to save energy.
D. It shows that the jet fighters form the best shape of a “V” formation.
57. The underlined word “imitate” in the last paragraph probably means “______”.
A. use B. change C. learn D. copy
58. The writer writes the passage to ______.
A. tell how migrating birds find their ways
B. explain how birds get help from migration
C. introduce some uses of migrating birds’ “V” formation
D. report new findings about migrating birds’ “V” formation

八、閱讀與表達(dá)(共10分，每小題2分)
閱讀短文，根據(jù)其內(nèi)容回答問題。
Hiking (徒步行走) in the countryside is one of life’s simple and cheap pleasures. But is it safe? Sport writer Mark Waters considers the dangers.
Imagine the following…
One day, Tom decided to take up hiking. Before going, he quickly looked at a map and decided that he could easily walk from the bus stop at Pak Tam Chung to the beach at Dai Long Wan.
After walking for hours and hours under the hot sun, Tom started to feel sick. He reached for his water but found that the bottle was empty. Then he smelt smoke and saw a fire. He called 999. However, he could not tell them where he was because he did not have a map.
Think about it …
Put yourself in Tom’s shoes. How could you stay away from the risks? One way is to learn the following common types of danger well.
1. Getting lost
Bad weather is one of the reasons why some walkers get lost. However, the most common one is not having enough knowledge of the hiking route (路線). Always remember to bring a map and don’t be too confident. Always choose a route that is right for you.
2. Heat stroke (中暑)
The summer in Hong Kong is very hot and wet. Many hikers forget this and walk for too long in the midday heat. They become hot and feel weak. Don’t forget it is necessary to drink 100 to 200 ml of water every 15 to 20 minutes.
3. Accident
Some of Hong Kong’s paths are very dangerous and it is not unknown for hikers to fall. Never walk alone and always bring a map and a mobile phone with you.
4. Hill fire
Every year, over 10,000 hill fires take place in Hong Kong, hurting more than 600 people. Never light fires unless you are allowed to and, if you see a hill fire, stay cool, walk away and report it quickly.
64. In Mark’s opinion, is hiking in the countryside safe or dangerous?
65. Why couldn’t Tom tell the police where he was?
66. What is the most common reason for people getting lost?
67. What will you do if you see a hill fire according to the passage?
68. What does the writer mainly talk about in the passage?
