三、阅读理解。(每小题1。5分，共15分)
A
The idea that red means "stop" and green means "go" has influenced our lives in more ways than just traffic signals(信号). We have been taught from a young age that the colour red means danger and green means it's okay to move forward. But why were those colours chosen for traffic lights in the first place? For things we have to look at every day, why couldn't they have been prettier colours?
Well, it's important to know that before traffic lights for cars, there were traffic signals for trains. At first, railway companies used red to mean "stop", white to mean "go", and green to mean warn . As you could imagine, trains ran into a few problems with white meaning "go". For example, one train mistook a bright star for a white light and something unexpected happened. Because of that, railway companies finally moved green meaning "go" and used yellow to mean "warn". And it's been that way ever since.
Red has always been a colour that means danger, long before cars were even around. This most likely started because it's the colour with the longest wavelength(波长) so it can be seen somewhere farther than other eolours.
But, believe it or not, yellow was once used to mean "stop". Back in the 1900s, some "stop" signs were yellow because it was too hard to see a red sign in a poorly lit area. Finally, highly reflective materials(高反射材料) were developed and red "stop" signs were born. Since yellow can be seen well at all times of the day, school zones, some traffic signs, and school buses continue to be painted yellow.
So next time you're impatiently waiting at a traffic light, don't get so mad at them’ they've certainly come a long way.
31. What were traffic signals for before traffic lights for cars?
A. Trains. B. Boats. C. Planes. D. Bicycles.
32. Which of the following colours meant "go" at first?
A, Red. B. Yellow. C. White. D. Green.
33. Why does red mean danger?
A. Because it's the brightest colour.
B. Because it can be seen far away.
C. Because railway companies say so.
D. Because it has the shortest wavelength.
34. Why are school buses painted yellow?
A. Because yellow is a prettier colour.
B. Because yellow once meant danger.
C. Because yellow can be seen well at all times of the day.
D. Because yellow means it's OK to go forward.
35. What does the text mainly tell us?
A. How important traffic lights are.
B. Which colour has the longest wavelength.
C. What red, yellow and green can be used for.
D. Why traffic lights are red, yellow and green.
B
Maybe a lot of thin people will be worried about their health if the inside fat matters.
Some doctors now think that the inside fat around important organs like the heart or liver could be as dangerous as the outside fat which can be noticed more easily.
"Being thin doesn't surely mean you are not fat," said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have tested nearly 800 people with MRI to create "fat maps" showing where people store fat.
According to the result, people who keep their weight through the food they usually eat rather than exercise are likely to have major deposits(堆积物) of inside fat, even if they are thin.
Even people with normal Body Mass Index(体重指数) scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores(20 to 25) actually had too high levels of inside fat. Men were nearly 60 percent.
According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the stomach first, but at some point, the body may start storing it elsewhere.
Doctors are unsure about the exact dangers of inside fat, but some think it has something to do with heart disease and diabetes (糖尿病). They want to prove that inside fat does harm to the body's communicatlon systems.
The good news is that inside fat can be easily burned off through exercise or even by improving your eating habits. "If you want to be healthy, there is no other way. Exercise has to be an important part of your lifestyle," Bell said,
( )36. What is this piece of news mainly about?
A. Thin people may be fat inside.
B. How to deal with inside fat.
C. Inside fat leads to many diseases.
D. Thin people also have troubles.
( )37. What does the underlined word "organs" in the second paragraph mean?
A. 地位 B. 地方 C. 器官 D. 肝脏
( )38. Doctors have found__________.
A. the exact dangers of inside fat
B. being thin doesn't mean you are not fat inside
C. being thin is not dangerous at all
D. inside fat is the cause of heart disease and diabetes

A. Exercise can help to reduce the inside fat.
B. People can reduce inside fat by improving their eating habits.
C. Women have more chances to have too much inside fat.
D. Not all the people who look thin are really thin inside.
( )40. From the last paragraph, we can find that___________.
A. it is true that inside fat can lead to disease
B. exercise plays an important role in people's life for keeping healthy
C. thin people usually have inside fat even if they are thin
D. it is easier to burn off inside fat than outside fat
四、任务型阅读。(每小题2分，共10分)
To make teenagers realize how hard it is to raise a baby, some children are asked to care for a bag of flour(面粉) as if it's a baby. However, raising a baby is a lot more difficult than that. Maybe the latest interactive(互动) robot RealCare Baby 3 can help solve the problem.
RealCare Baby 3 is designed to be used in a training programme for teenagers or other people who need the experience. The robot makes it possible for people to practise looking after a baby 24 hours a day, seven days a week. To do that, they must wear a special bracelet(手镯) which can send out signals(信号) to connect to a receiver in the robot.
The robot is the same weight as a real baby and has got different sensors(传感器) inside. It may start crying at any time of the day or night and its "parent" must come to look after it within two minutes. A data logger(数据记录器) will record any delay(耽搁). Once the parent gets to the baby, he or she must pick it up softly, holding its head at the same time. If the parent doesn't do it in the right way, the baby will cry louder and the logger will keep a record again. Then the parent needs to find out why the baby cries and think of ways to stop it from crying. Besides baby's cries, the parent also needs to remember to chanae its clothes according to different temperatures to prevent it from getting too hot or too cold,

Life on Mars in the future
In the future, people would move to other planets including Mars because the Earth is becoming more and more crowded and polluted. What would life on Mars be like? Let's go and have a look.
The gravity on Mars is only about three-eighths of that on the Earth, so people would have to wear special boots to keep themselves from floating off into space when they go out. People would have more space and they would live in big, comfortable rooms. What's more,people could have more time to relax because robots would do most of the work. The food on Mars would be
in the form of pills. It would not be as tasty as that on the Earth.
There would be no schools on Mars. Every student would have a computer at home connected to an interplanetary network. They would study at online school with e-teachers. The spacecraft would travel very fast, but it is not very comfortable.

Life on Mars in the future
In the future, people would move to other planets including Mars because the Earth is becoming more and more crowded and polluted. What would life on Mars be like? Let's go and have a look.
The gravity on Mars is only about three-eighths of that on the Earth, so people would have to wear special boots to keep themselves from floating off into space when they go out. People would have more space and they would live in big, comfortable rooms. What's more,people could have more time to relax because robots would do most of the work. The food on Mars would be
in the form of pills. It would not be as tasty as that on the Earth.
There would be no schools on Mars. Every student would have a computer at home connected to an interplanetary network. They would study at online school with e-teachers. The spacecraft would travel very fast, but it is not very comfortable.
