In China , more and more middle school students are getting shorter sleeping time than before. Most students sleep less than nine hours every night, because they have much homework to do. Some homework is given by their teachers, and some by their parents. Also, some students don't know how to save time. They are not careful enough while they do their homework, so it takes them a lot of time. Some students spend too much time watching TV or playing computer games. They stay up (熬夜) very late. Some students have to get up early every morning on weekdays to get to school n time by bus or by bike. It can be a long way from home to school.

　　Schools and parents should cut down some of the homework so that our children can enjoy more than nine hours of sleep every night for their health. For children, we should make best use of our time. When we have enough time for sleeping, we will find it much better for both our study and health.

“Sorry” is a word that people in Britain often say in their daily life.

One day while I was w　 1　 on the street, a young man ran by hurriedly, brushing（轻擦）against my handbag. He continued his way, but turned b 2　 and said “sorry” to me. Even in a rush, he didn’t f 3　 to say “sorry”. One day, after I bought some bananas, the shopkeeper was passing me the change, but I wasn’t ready for it and a coin dropped onto the ground. “Sorry, Madam,” he said w 4　 bending to pick it up. I was s 5　 why he said “sorry” to me. Another time, I stepped on a man’s f　 6 at the entrance to a cinema. At the same time, we b 7　 said “sorry”.

Slowly, I got to know that when something unpleasant happens in daily life, the British don’t

c　 8　　 much about who is wrong. If someone is in trouble, a “sorry” is always n 9　 .　 Perhaps that is w　 10　 I seldom see people quarrel on the buses or streets in Britain.

In Britain, people have different attitudes(态度)to the police. Most people generally   1  them and the job they do, but some people said that the police shouldn’t    have special   2 .
What does a policeman actually do? It is not a(n)  3  job to describe. After all，a policeman has a number of jobs to do.

A traffic policeman has to help keep the traffic moving，stop speeding cars and help when there is a(n)  6  .
A policeman has to help keep the  7 ，too. If there is a fight, we  8  the police to come immediately. And they often have to deal with situation at great risk of their own  9 .
We want the police to solve crimes，of course，so an ordinary(普通) policeman,    10  he is not a detective，he will often have to help   11  criminals.

So a policeman has to  13  to face any terrible emergency that may happen in the modern world.
The police do a  14  job，they do it so well that I support them. But I do not envy policemen. I do not think that I could   15  do the job of a policeman.
