Astronauts on board the Shenzhou-10 spacecraft have taught a lesson from space to schoolchildren through a live video. The astronauts made some experiments in the lab Tiangong-1. They showed a lot of physical(物理的) phenomenon（现象） in a zero-gravity（失重的） environment.
Greetings from space have opened a new history in China.
Wang Yaping, Shenzhou-10 Astronaut, said, "Hello, everyone. I am Wang Yaping. I will host the lecture today.” It is the country’s very first space lecture. And all eyes were on the female space teacher Wang Yaping and her two other partners.
The first part of the class was all about weight. This floating（漂浮的） pose looked like a pose from a Chinese Kongfu movie. Audiences were amazed by it.
Wang Yaping later did some other experiments to show what happens in zero gravity. She also did an experiment of what water is like on space.
In Beijing, about 330 students attended the class and ask questions of the astronauts from video calls.
Song Xinke said, "It’s very interesting. The experiment that impressed me a lot is the water balloon. The phenomenon is very beautiful. We have not learned enough knowledge to understand it. So I want to learn more after the class."
Liu Yuezhang said, "I feel very excited about this class. I have lots of questions and the astronauts are answering our questions. They teach us a lot of knowledge."
China’s very first lesson from space was a new chapter（篇章） in history. The experiment is sure to be a great encouragement for the young to explore the unknown. And get a greater understanding of the universe.

The world is not hungry , but it is thirsty . It seems strange that nearly 3/4 of the earth is covered with water while we say we are short of water. Why? Because about 97% of water on the earth is sea water which we can't drink or use for watering plants directly. Man can only drink and use the 3% - the water that comes from rivers and lakes. And we can't even use all of that, because some of it has been polluted .
Now more water is needed. The problem is: Can we avoid (避免) a serious water shortage later on? First, we should all learn how to save water. Secondly, we should find out the ways to reuse it . Scientists have always been making studies in the field. Today, in most large cities water is used only once and then runs to the sea or rivers . But it can be used again. Even if every large city reused its water, still there would not be enough. What could people turn to next?
The sea seems to have the best answer. There is a lot of water in the sea. All that needs to be done is to get the salt out of the sea water. This is expensive, but it's already used in many parts of the world. Scientists are trying to find a cheaper way of doing it. So you see, if we can find a way out, we'll be in no danger of drying up.The world is thirsty because ________.
| A．3/4 of the earth is covered with water |
| B．we have enough sea water to use directly |

| B．man can only drink and use about 25% of water on the earth |

| B．Don't pollute water and keep all rivers and lakes clean. |
| C．Make dirty water clean and then reuse it. |

A thousand years ago, Hong Kong was covered by a thick forest. As more and more people came to live in Hong Kong, these trees were cut down and burnt. Now there is no forest left, though there are still some small areas covered with trees. We call these woods.
Elephants, tigers and many other animals were living in the thick forest. When people came to live in Hong Kong, the animals began to die out. Early farmers grew rice and kept pigs and chickens in the valleys. They cut down the trees and burnt them. They needed fire to keep themselves warm in winter, to cook their food and to keep away the dangerous animals. Elephants quickly disappeared because there was not enough food for them. Many other animals soon died in the same way.
You might think that there are no longer any animals in Hong Kong except in 2005. But there are still about 36 different animals living there. One of the most interesting of Hong Kong’s animals is the barking deer. These are beautiful little animals with a rich brown coat and a white patch under the tail. They look like deer but they are much smaller. They are less than two feet high. They make a noise rather like a dog barking. In Hong Kong the barking deer has only a real enemy—— men. People hunt these little animals though it is illegal, There are now not many barking deer left.

It seems to be strange to you there is a blind spot(盲点)on the eyes, Here is an interesting experiment(实验)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, Lon 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' 11 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（影像）of the letter falls on the blind spot, it won't be seen. That is why either of the letters disappears．The writer of the passage thinks that_______ there is a blind spot on the eye.

Mr. Brown was on his way home from the railway station. It was very late, and he was alone on the dark road. Suddenly he heard someone behind him. He began to walk faster. The man behind him walked faster, too. He walked more slowly, and the man moved more slowly, too. He began to run, and the man was following him and he was really scared.
There was a wall on one side of the road, and he quickly climbed up on it and jumped down on the other side. "If he passes and doesn't stop," Mr. Brown thought, "everything will be all right." But the man didn't pass. He climbed up on the wall and jumped down, too. Mr. Brown's only thought was, "I'm in great danger!" He stood up and shouted, "What do you want? Why are you following me?"
The man was so tired that at first it was difficult for him to speak. "I didn't know that you were a very good runner," he said at last, "I have to go to Mr. White's house, but I don't know the way.

You may know the English letters A,B and C. But do you know there are people called ABC? You may like eating bananas. But did you know there is such a thing as a "banana person" "How strange! Are these people from "another earth"? No. They are just Chinese people like you and me.
ABC means American-born Chinese. An ABC is a Chinese, but was born in the United States. Sometimes, people call an ABC a "banana person". A banana is yellow outside and white inside. So, when a person is a banana, he or she is white inside - thinking like a Westerner and yellow outside - looking like a Chinese.
Do you know why? Usually, ABCs know little about China or the Chinese language. Some of them don't speak Chinese. But if ABCs cannot speak Chinese, can we still call them Chinese people? Yes, of course. They are Chinese. They are overseas Chinese. These people may be citizens of another country like the US, Canada or Singapore. But they have Chinese blood, Their parents, grandparents or even great-grandparents were from China They all have black eyes and black hair.
But they are not Chinese citizens. They are not people of the PRC. For example, we all know the famous scientist C. N. Yang (杨振宁). He got the Nobel Prize for Physics in 1957. Chinese people love him. But he is an American citizen."ABC" in this passage means"_______ ".
