DNA is the whole "map" of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.
People have been trying to understand the human body for a long time. In I860, Mr Mendel discovered why we look the same as other people in our family. It is because of small things called "genes"(基因) in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are really messages. They’re written in the DNA with a special language.
In 1961, another two scientists found the first "word" that they could understand in that language. It shows how DNA tells the cell (细胞)to build its parts, the words in the DNA map, but we still do not understand what they all do. By understanding what just one "word" means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do.
Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more "words" and find out more information, we will use it in the wrong way, just to make people more attractive, or stop sick people getting jobs.

The message was short. I read it three times: “Hey, Mom, can I come to see you?” I wrote back: “Yes!” He said he hoped to make it in time for dinner.
I made a quick run to the market, put sheets on the guest bed and set the TV to record the Warriors’ game, so if traffic was awful, he wouldn’t have to miss the first half. Then I began cooking, cleaning, watching the clock and listening for his footsteps coming up the walk.
It’s called waiting. I’m good at it. When he was a newborn, I’d wait for him to go to sleep. Soon then I’d stand by his bed waiting for him to wake up. I waited, as he learned to do things like walking, talking and feeding himself; throwing a ball, riding a bike and reading a book.
I waited for him to start preschool, primary school, middle school and college.
I waited with dread for him to start driving. And I waited up every time he came home late.
I wait for my son to grow up, but that doesn’t mean the waiting game is over. It never really ends.
Mothers wait for all kinds of reasons—good news or bad, happiness or heartache. But the waiting is soon forgotten, usually, the minute a long awaited child walks through the door.
My boy will be here soon. But if he’s late, I can wait. I’m good at it. And he’s worth(值得) it. I will always leave a light on for him.

Some city schools have brought WeChat(微信) into the classroom now. Students and teachers communicate by WeChat. Is WeChat good to use in classroom? Here come some different voices from students.

I don’t think we should use WeChat in class. We need to use mobile phones for Wechat. But it is hard for teachers to manage the class. Some students can’t control themselves if they have mobile phones. They will use them to play games or QQ in class. So I think it is not necessary to use WeChat in class. --Guo Ruiting, 14, Guangdong	I think it’s good for teachers to use Wechat in class. When they raise a question, all students will be glad to answer it on Wechat. They don’t have to raise their hands, but just use the keyboard to note down a few words. And the way helps to relax everyone. It helps us to answer questions as well. --Zhang Yaoyi, 12, from Shanghai
We used Wechat in class once. It was good. Everyone was excited to see their words on the screen. Some students used to be shy in class. They didn’t speak in class. But everyone was surprised to see them talking a lot on WeChat. So I think it is good for us to use things like Wechat in class. --Liu Qing, 15, from Zhejiang	We chat is good for class. However, we must use it carefully. When we use it in class, most students are excited to take part in activities and happy to talk about any questions. Surely, teachers are able to manage the time and control the class, or the class must be a little bit messy. --Sun Jiayang, 13, from JIangsu

Nowadays, computers and Internet are playing an important part in our life. We usually need to set passwords(密码) when we use computers and Internet. In order to keep our accounts (账户)and personal information safe, we must learn how to set safe passwords.
Experts have some useful advice for you. You’d better remember them. First, make your password out of capital(大写的)letters. It only takes a hacker(黑客)10 minutes to work out a 6-letter password made of small letters. But the same password in capital letters takes 10 hours to work out. Second, add numbers or symbols to your password. It may be much safer. Third, never use personal information for passwords and use different passwords for different accounts. At last, a user should change his or her passwords every 90 days. In this way, hackers won’t guess your passwords.
