If you want to watch and know something about birds, you must find a good place near the bird nest（巢）.

Birds sit on eggs and take care of their babies from April to June. Because the baby birds are too young to leave the nest, parents often go to look for food and come back in several minutes. So it is good to watch birds. When we watch birds, we’d better hide ourselves in a close place to the nest, and it’s better to use binoculars(双筒望远镜).

But how to make a bird nest? A good bird nest must be very fine, strong, thick and comfortable. If you want to make one, please follow these:

a) Each nest must have six boards（木板）. Don’t make the boards too slippery（滑）.

b) Dig a small hole in the front of the nest as a “door”. The “door” is big enough so birds can fly in or out easily.

c) Make sure the rainwater can’t go into the nest.

d) One piece of the board should be easy to open.

e) Don’t forget to colour the nest.

Gasoline (汽油) prices are getting higher and higher. The prices make it hard for drivers to afford the fuel.

??? One group held a special event to display（展示）new kinds of cars .

The new cars are different and they can run on many different kinds of fuels .

Some of these cars are called hybrids(混合动力). They can run on different kinds of fuels . One kind of them runs on a special fuel cell which is filled with a gas called hydrogen(氢气). ___1.___? They are very clean , and don’t give off bad fumes(烟雾) when they run .

The man who makes fuel cell cars is excited about the technology .__ 2.___ Once we use oil up , it will take millions of years for more oil to form. Since gasoline is made from oil , that could be a problem for companies that make traditional cars , and for drives . __3.__

?? Buses that run on hydrogen fuel cell power are being tested on the road . They could become a common form of transportation in the near future

4.What do you think of this kind of new cars ? Why ?

It seems to be strange to you there is a blind spot(点) on the eyes. Here is an interesting experiment that can make something disappear, when one eye is open.

　　Make a card about the size of a postcard and write two English letters L and R on it, L on the left and R on the right. First, hold the card about 80 cm away and you see both the letters. Then close your right eye and look at the letter R only with your left eye. And now, as you move the card slowly towards you, you’ll find the letter L disappearing. But if you move the card nearer to your face, the letter will be seen again. Now do the same experiment with your left eye closed, you’ll find the letter R disappearing.

Why does the letter disappear? It is because there is a blind spot on the eye. When the image of the letter falls on the blind spot, it won’t be seen. That is why either of the letters disappears.

1.The writer of the passage thinks that _____ there is a blind spot on the eye.

A．few people know   B．no one knows      C．most people know   D．all the people know

2.In which order should you do the experiment?

①Hold the card  ②Move the card nearer   ③Close your right eye

④Write two English letters  ⑤Look at the letter R   ⑥Make a card

A．④⑥①②③⑤      B．①③⑥④⑤②      C．⑥①④③②⑤      D．⑥④①③⑤②

3.The passage mainly tells us _______.

A．how to find the blind spot                 B．an interesting experiment

C．where the blind spot is                   D．there is blind spot on the eye

Cars are lots of fun, but they could also be dangerous. We have to be careful when we drive them or ride in them.

It's always a good idea to put on your seat belt when you're in a car. Why? Think about this example: You put an egg on a skateboard and give it a push. If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break.

Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying; it will stay safely on the skateboard.

Volvo, a famous Swedish carmaker, was the first to use seat belts in 1849.

Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most new cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly in less than one second to keep the people inside safe.

4.Air bags are important for cars because _.

C. When a car hits something, its air bags will come out a few minutes later.

People often say that the earth is like our mother. She gives life to all the living things on the earth and provides us with air, food, water and other essential things we need for living.
Once she was beautiful and rich, but now she becomes dirtier and dirtier, poorer and poorer. It is due to what we have done to her. Please have a good look at her: polluted rivers and lakes, growing deserts, the destruction of the forests and wild life, and the depletion (消耗，用尽) of the ozone layer (臭氧层)...
Can she bear to see her children putting the waste here and there? Can she bear to see her children cutting down the trees and destroying the grassland, to see the acid rain destroying everything? Can we bear to see our mother suffering (受苦) so much? Isn’t it time for us to ask ourselves whether this is the way to treat our mother?
Floods, droughts, acid rain..., these are the punishments (惩罚) from nature. Everyone should know that there is only one earth. If we go on treating her like this, it won’t be fit for us to live in any longer. It’s time for us to love her, take good care of her and cure her. We should save the earth so as to save ourselves.
