[1] Look at the center circles of Diagram A and Diagram B. Which of the centre circles looks larger?
[2] Take a first look and you probably think that the centre circle in Diagram A is smaller than that in Diagram B. In fact, they are exactly the same size.
[3]Then look at the picture on the right.What do you see? A vase? Or two faces? Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can see them at the same time.
[4]“What’s happening? Is something wrong with my eyes?” You may wonder at what you see. Don’t worry. Here is how it goes:
[5]When we look at things, our eyes send messages to our brains and then our brains interpret (解释) the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it “Visual illusion(幻觉)”.
[6] Movie makers often make use of illusions. They make the objects around actors much smaller or bigger than usual. This makes us believe that the actors are much larger or smaller than they usually are. The movies Jurassic Park and Honey J shrunk the kids just make use of illusions.

As you may ex
pect, life in space is much different from life on earth. So of course people need some time to get used to it. How do they live, work and play up there?
Space food keeps getting more like the food we eat at home on the earth. In the past, astronauts could eat only freeze-dried food. But now the space station has water, microwave ovens and fridges. So astronauts can eat more usual kinds of food, like fruit, vegetables and ice cream!
All people in the ISS（国际空间站）have their own rooms. There’s no gravity, so they have to attach themselves to their beds, or they’ll float away! That may seem like a hard way to sleep, but astronauts say that sleeping in space is actually not too bad.
This is more important in space than on Earth. There’s not much gravity in space. Astronauts don’t stand up, sit down or walk in space, so their muscles don’t have to work much. They exercise on bikes and other machines for about two hours every day while they’re in space. In this way, they can still keep strong and healthy when they get back home.
Easy things like brushing your teeth can be hard in space with low gravity. Water doesn’t flow out of a tap, it floats in a bubble（水泡）! Astronauts used a special hose（软管）to take showers. And when they’re finished, they use a vacuum（真空的）hose to suck the dirty water off of their bodies. How do y
ou go to the toilet in space? They use a special “air toilet”. It uses air, not water, to take everything away.
What do astronauts do when they aren’t working? They read books, play cards, listen to music or send e-mail to their friends and family. Sometimes they just sit and look out the window. Doesn’t sound like much fun? But what if
you could see planet Earth out of your window, with a sunset or sunrise every 45 minutes?

1970 was “World Conservation Year”. The United Nations wanted everyone to know that the world was in danger. They hoped that the governments would act quickly in order to conserve nature. Here is one example of the problem. At one time there were 1300 different plants, trees and flowers in Holland, but now only 860 remain. The others have been destroyed by modern man and his technology. We are changing the earth, the air and the water, and everything that grows and lives. We can't live without these things. If we continue like this, we shall destroy ourselves.
What will happen in the future? Perhaps it is more important to
ask “What must we do now?” The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation is necessary. Many are hoping to save our world. They plant trees, build bridges across rivers in forests and so on. In a small town in the United States a large group of girls cleaned the banks of eleven kilometres of their river. Young people may hear about conservation through a record called “No, One's Going to Change our World. ” It was made by Scatles, Cliff Richard and other singers. The money from it will help to conserve wild animals.

Paragraph 1
Scientists have learned a lot about the kinds of food people need. They say that there are several kinds of food that people should eat every day.

night. The important thing is what you eat every day.

For years , many people would not believe that smoke could attack so many parts of the body in so many ways . Study shows , however , that tobacco isn’t one single thing . At least 60% of it is gas—20 different kinds of gas . And one of these is the deadly carbon monoxide (CO) （一氧化碳）.
In factories , the amount of this gas in the air is measured , and it must be kept under fixed , safe level . But there is 640 times this safe amount in cigarette smoke .
Oxygen is carried through your body by the red blood cells . But this poison gas , CO, will get to the blood cells before the oxygen can . So , if you smoke your blood carries five to ten times more of this deadly gas than is normal . To make up for this , your body must make more red cells .
The oxygen in your blood passes into your tissues（组织）. But here again C
O makes trouble . It keeps the oxygen from passing into your tissues as fast as it should . Because of this , cigarette country is always about 8000 feet above sea level . Someone who smokes and lives at sea level gets as little oxygen as a nonsmoker at an altitude（高度）of nearly two miles .This happens to everyone who smokes , no matter how old or how young . Anyone who competes in sports can tell you that those who smoke run out of breath more quickly than those who do not .
1．The gas amount in cigarette smoke is______________.
A．640 times higher than the gas safe levels in factories
B．640 times lower than the gas safe levels in factories
C．640 times as much as that in factories
D．as dangerous as that in factories
2．If you smoke , ______________ .
A．your blood carries more oxygen than is normal
B．your blood carries much more CO than is normal
C．you can have five to ten times of blood than usual
D．your blood will be poisonous
3．Those who smoke______________.
A．all live at sea level
B．don’t live at an altitude of two miles
C．breathe as much oxygen as non-smokers
D．only get the same amount of oxygen at the sea level as non-smokers at an altitude of nearly 2 miles

The report came to the British on May 21, 1941. The German battleship Bismarck , the most powerful warship in the world , was moving out into the Atlantic Ocean . Her task : to destroy the ships carrying supplies from the United States to war-torn England .
The British had feared such a task . No warship they had could match the Bismarck in speed or in firepower . The Bismarck had eight 15-inch guns and 81 smaller guns . She could move at 30 nautical miles （海里）an hour . She was believed to be unsinkable .
However , the British had to sink her . They sent out a task force headed by their best battleship Hood to hunt down the Bismarck . On May 24 , the Hood found the Bismarck .
It was a meeting that the German commander Luetjens did not want to see . His orders were to destroy the British ships that were carrying supplies , but to stay away from a fight with British warships .
The battle didn’t last long . The Bismarck’s first torpedo （鱼雷）hit the Hood , which went down taking all but three of her 1419 men with her .
But in the fight , the Bismarck was slightly damaged . Her commander decided to run for repairs to France , which had at that time been taken by the Germans . The British force followed her . However , because of the Bismarck’s speed and the heavy fog , they lost sight of her .
For two days , every British ship in the Atlantic tried to find the Bismarck , but with no success . Finally , she was sighted by a plane from Ireland , Trying to slow the Bismarck down so that their ships could catch up with her , the British fired at her from the air . The Bismarck was hit .
