In order to improve students’ health and reduce (减少) students’ pressure, our country made some rules. Here are some of them.

Firstly, homework for middle school students should take no more than 90 minutes. They can finish most of written homework at school so that after school they only spend a little time finishing the rest. Some students can still go to sleep on time even though they don’t finish their homework until bedtime. Then they will have more time to relax. Secondly, mobile phones mustn’t be brought to class because students are easily absent-minded (心不在焉的) from the lesson. Students must control the time on electronic products to protect their eyesight. They shouldn’t lose themselves in the Internet. Thirdly, students are expected to listen carefully and go over lessons in time so that they can master the right way of learning. Fourthly, parents should often communicate with their children, pay attention to their feelings and help them develop good learning and life habits.

In a word, these rules are helpful to middle school students. If they follow the rules, they can improve their study and health.

A lift is very useful. It looks like a small room. It goes up and down all day. Sometimes a worker stands in the lift. He or she operates（操作） it up and down. In modern lifts there's no worker. People walk in. They know what floor they want to go. They push a button(按钮)and the lift goes to that floor. It's very fast and easy.

Lifts are very important to us. Why? Think about a tall building. Maybe it has twenty floors. Maybe it has fifty or more. Who can walk up all the stairs (楼梯 )?Maybe people can climb them once. Can someone climb thirty floors to an office every day? Can small children walk up to their rooms on the twenty-four floor? Can their mothers or fathers carry food up to all those stairs? Of course not. We can have very high buildings because we have lifts. We could not have all the beautiful tall buildings without lifts. Because it is too tired for people to climb the stairs every day.

With a history of more than 1,800 years, dumplings are a classic Chinese food. They are also a traditional dish on Chinese New Year’s Eve(除夕). They are really popular in China, especially(尤其) in the north of China.

Dumplings usually look like Chinese silver ingots(银元宝). Chinese people like to eat dumplings. There are some interesting ideas about them. For example, the more dumplings you eat during the New Year celebrations, the more money you can make in the new year. Dumplings have different tastes because of their different fillings(馅). There are many different kinds of fillings. Some popular fillings are pork, shrimp(虾), fish, chicken, beef, mutton and vegetables. Different people like to eat dumplings with different fillings. As for me, I like dumplings with mutton best.

Do you know how to make dumplings? Almost all Chinese people can make dumplings. They think it’s very easy to make dumplings. Here is a recipe for making dumplings.

First, mix the dough(面团).

Second, make the dough into round wrappers(面皮) with a rolling pin(擀面杖).

Third, fill the wrappers with fillings.

Fourth, pinch(捏) the wrappers together.

And fifth, cook them in the hot water.
