二、阅读理解
A
There are many colours in nature. But do you know that a colour has weight I think you’ll say “no”. But I am afraid you are wrong. If you don’t believe, you may do a small experiment (实验).
First, put two objects with the same weight into two boxes. Then cover the boxes. Wrap (包裹) one box with a red piece of paper, the other with a white piece of paper. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier.
Why does it happen A scientist found that different colours have different weight in a man’s mind. So he did many tests and at last he got the result. That is to say, every colour has its own weight in our mind. The heaviest colour is red, then blue, green,. orange, yellow and white. The scientists told us that colours also have smell. Can you smell the colour Of course not Then why did the scientists say so That is because every colour represents a kind of light wave (光波)------ a certain wavelength (波长). It reaches our brain (大脑) through organs (感觉器官)
According to this discovery, scientists say that people accept the colour they like, and refuse the colour they hate. So your body and mind will be healthy by using the colours you like. Or you’ll be nervous or even get ill. If you stay in a room with red windows, wallpapers and furniture (家具) for two hours, you’ll feel you have been there for four hours. But if the room is blue, you’ll feel you have been there for only one hour. Another example, if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change when we see different colors.
1. Which is the lightest color in a man’s mind
A. Red B. Blue C. Green D. White
2. Which of the following is NOT true
A. Different colors have different weights in a man’s mind.
B. The color “blue” is the second heaviest color in a man’s mind.
C. People can’t smell the colors.
D. The color you don’t like will keep you healthy.
3. What will happen when you get into a cool colored room from a warm colored room
A. You will feel excited. B. You will be happy and contented.
C. Your temperature will fall. D. You will be nervous.
4. According to the passage, how long will you feel if you stay in a red room for an hour
A. Two hours. B. Fours hours C. Six hours D. Eight hours.

Let’s try doing the following experiment.
What to do：
Use string to hang a paper clip or other small object at about chest（胸部）level.
Pick up a stick，such as a broom handle. Take three or four steps away from the paper clip.
Now close one eye and walk toward the paper clip. Try to touch it with the tip of the stick. If you miss，try again，still keeping one eye closed. Now try it with both eyes open and see if it’s easier to do.
How it works：
In the experiment，you have to judge how far away the paper clip is. Your brain has several ways of doing this.
One simple way depends on how much your eye has to focus（聚焦）itself. Using only one eye，most people will find it difficult to touch the paper clip on the first try，but the brain still gets some information about distance—though not much.
Your brain can judge distance much better when you look at something with both eyes. In fact，your brain has more than one way to use both eyes in judging distance. For example，to see anything clearly，you have to make both of your eyes point at the object. When you look at a nearby object，your eyes turn inward. You can feel this happening if you look at the tip of your finger and move your finger toward your nose.
Your brain gets information from the eyes about how much they are pointing toward each other. Using that information，the brain can tell how far away any object is，whether it is a basketball or a paper clip.
1.How many materials do we need at least to do the experiment？
A. Two B. Three C. Four D. Five
2.The passage is mainly about that with eyes our brain can judge .
A. how big an object is B. how high an object is
C. how far away an object is D. how much information an object is
3.Which of the following is true according to the passage？
A. Our brain judges distance in one way when we use both eyes.
B. Our brain cannot judge the distance of a small object but a big one.
C. How much our eyes focus helps our brain judge the size of an object.
D. How much our eyes focus helps our brain judge the distance of an object.
4.From the experiment we can infer（推断） .
A. with one eye we can see an object as clearly as we use two eyes
B. our eyes turn towards the inside when we look at an object very near
C. within 3 or 4 steps，the nearer an object is，the more clearly we can see it
D. our brain can hardly get any information about distance when we use one eye

C
For many years scientists have said that the earth is getting warmer. Now they have found something new-hot cities! In the southern US, they have found that cities become very hot in summer. For example, the city of Atlanta in Georgia has roof temperature of up to 50℃ while it is 27℃ in the streets! At night, the outside of buildings stays so hot that the heat of the city causes storms over the city!
China also has the same kind of problems. Every year more farmland is used for factories or offices. More housing is needed, too. As people become richer, they buy more cars. New roads are needed and new car parks are built in the city centers. This all makes cities hotter.
It isn’t easy to change the situation. City planners say that we should plant more trees in the middle of cities. Every new street should have trees on both sides, they say. Trees make the temperature lower, so we should have more trees in our parks and squares. We should also paint our roofs white. If we do this, they do not become so hot. Every roof in a hot and sunny country should have solar roof panels. The electricity from these can be used to run the air conditioners in the buildings.
People continue to cut down forests around the cities. This makes the problem worse. Cities are growing faster and faster. By the year 2025, four fifths of the population will be living in cities. If we go on like this, there will not be enough farmland to feed everyone in the world
1: What is NOT the reason that makes cities hotter
A．There are lots of storms
B．People need more housing
C．More cars are bought
D．City centers have more roads
2: Which is one way to make the city cooler
A．To plant more trees
B．To use air conditioners more
C．To build more parks and squares
D．To paint the walls white
3: What will probably happen in the future according to the fourth paragraph
A．Cities won’t grow very fast
B．We will not have enough food
C．Most people will move to the countryside
D．People will plant more trees outside the cities
4: What is the best title for the passage
A．More Farmland Is Needed
B．Trees Make Cities Cooler
C．Cities Are Getting Hotter
D．Scientists Are Worried About Storms
【答案】1.A 2.A3.B 4.C
三、书面表达
假如你是“保护动物协会”会员，请你根据下面的提示，以“Giant Pandas”为题写一篇短文。
提示：
1、大熊猫是黑白相间的，看上去像熊；
2、生活在中国，以竹笋(bamboo shoot)和竹叶为主食；
3、森林的数量越来越少，没有足够的食物吃，只有大约100只了；
4、应采取的保护措施；
5、假如再不采取措施，不久就可能有大熊猫了。
【答案】
Giant pandas are black and white animals. They look like bears. They live in China. They eat bamboo shoots and leaves. Sadly, giant pandas face serious problems in the wild. The forests are getting smaller and smaller. They don’t have enough food to eat. There are only about a thousand giant pandas in the world now.
We should take the following actions to protect giant pandas: help pandas have more babies, build more panda reserves, make laws to protect pandas. If we do nothing, soon there may be none left in the world.
