Thomas Edison was a famous American scientist. When he was        child, he liked to find out        things worked. In school he asked his teacher a lot of questions which had nothing        (do) with his lessons. So his teacher thought he was not worth        (teach).Soon he got very        (interest) in science.

Once he thought out a good idea to make the room bright        (save) his mother's eyes.        he was 15, he saved a boy and he learned to send messages        railway telegraph from the boy's father. Ever        then, he never        (stop) searching for new and better ways to do things.

    Nowadays, Wechat is becoming more and more1in China. No matter where we are, we can send text or voice messages to our friends. We can also find a stranger to talk to by shaking the 2. Another funny function(作用) is that Wechat can help to search for people 3 live nearby with the app on. Many people like this function, 4 it can help them to find more people who they may know.

    In my opinion, Wechat is really 5 useful chatting tool. It can help people 6 with their friends more easily. 7, it is also bad for people, especially for students. As you see, some people use Wechat 8 too long. It is not healthy. So I have some advice on using it in a correct way. First, we should not use it when we are studying. We can't focus on our study if we use it. Second, we must be careful. We should neither show too much personal information 9 trust(相信)strangers so much

    We should learn how to use it properly(正确地). Remember, Wechat is not everything in your life. 10 depend too much on it.

Dear editor (编辑)

I live in a beautiful city. Many visitors come to my city. There are so many colorful peacocks (孔雀) here. The peacocks mostly live on the grass land of Dong Feng Square.

They are given food freely by visitors. They usually throw food to them, and don't think about at all whether the food is right or not. Some of the peacocks became ill, some even died after eating the bad food given by the visitors. I'm sure most of the visitors who throw food to the peacocks really like the birds, but don't realize that they may be doing them harm.

The visitors should be told that what have done is very harmful to the birds, and this kind of thing must stopped from happening.

Perhaps we can build some small shops beside Dong Feng Square to sell peacock food. For us every person, it's our duty to give more love to these beautiful birds and to look after them carefully.

Yours.

Sun Yan
