In most parts of the world, many students help their schools make less pollution(污染). They join “environment(环境) clubs ”. (1)In an environment club, people work together to make our environment clean. Here are some things students often do.

    No garbage(垃圾) lunches. How much do you throw away after lunch? Environment clubs ask students to bring their lunches in bags and the bags can be used again. If the classes make the least garbage, we will report them to the whole school!

No car day. On a no car day, nobody comes to school in a car—not the students and not the teachers! Cars give pollution to our air, so remember: Walk, jump, bike or run. Use your legs! It's lots of fun!

    Turn off the water! Did you know that some toilets(厕所) can waste(浪费) 20 to 40 m³ of water an hour? In a year, that would fill a small river! In environment clubs, students mend(修理) those broken toilets.

    We love our environment. (2)Everyone should take _______ to make our environment ______. Let's work together.

A. A fire engine will arrive quickly. The firemen know what to do. They have long ladders to reach high windows.

B. If you want to be a fireman，you must be strong and healthy. A fireman has to be able to carry heavy things. He has to be able to climb ladders and to work in high places. So he also has to be brave.

C. They try their best to rescue the people who can't get out. If some people are hurt，they are taken to hospital in ambulances（救护车）.

D. When a fire begins，we must tell the fireman. Do you know how to do this？

E. After all the people have been rescued，the firemen put out the fire. Sometimes this is very difficult because some people keep things in passages and on stairs. Then the firemen can't get past to fight the fire.

F. Go to the nearest telephone and dial the number 119. When someone speaks，tell him about the fire. Speak slowly and clearly.

    Every four years, the best players from all over the world get together in one city to ①________ the world sports meeting the Olympic Games. People carry the holy flame from one place to the nest. On August 6th, 2008, they carried the holy flame to Beijing. All the Chinese people were very happy, excited and proud.

    In Beijing, we built a new Olympic Village with restaurants for players and stadiums for matches.

    The motto of the Olympics is "Faster, higher, stronger". The slogan (标语，口号) of the Beijing Olympics is "②________".

    Who's building the new China? It's not the factory owners or the business men and women of China. It's someone else. We see them every day. They work day and night in the terrible working conditions and weather. They build the roads, the theatres, the cinemas and the supermarkets, They even clean up our rubbish. They are China's migrant workers(民工).

    More than 140 million workers have left their homes in the countryside to look for jobs in big cities all over China. They hope to be rich, but they realize they have many difficulties in making enough money. And one of the difficulties that these workers have is the discrimination(歧视)from the people in cities. Migrant workers are living far away from those who they love. Yes, they dress differently, they speak differently, and they have different habits, but they work hard. The people in cities treat them as outsiders, and most governments don't want to give them medical care and public schooling for their children. If China hopes to move into the future, many things need to change. The first is discrimination！We need to stop our discrimination！They may not make as much money as some people do in cities, but they are good honest people just trying to survive this game of life. These workers are very important and necessary to China's economic(经济)development and have become an important force for the change of Chinese society. They are building the new China, so we should help them.

It's early in the morning and the alarm clock has already rung several time. You have to pull yourself out of bed and rush to school because you're afraid of being late for school.

As a school student, this is probably a common experience for you. But thanks to new rules, students in Zhejiang and Heilongjiang provinces can now stay in bed longer than before.

On Feb 23, the Zhejiang Department of Education announced (宣布) a new rule that asks primary schools to start school later. According to the rule, start times could be different among different grades, with students in Grade 1 and 2 starting no earlier than 8:30 am.

A similar guideline (指导方针) was announced by the education department in Heilongjiang Province on Feb 24. Students from all primary and junior high schools in the province have been required (要求) to arrive at school no earlier than 8 am.

According to a 2016 study by the Zhejiang Department of Education, half students in Grade 4 slept nine hours or more a night, while the enough sleep time for primary students in 10 hours.

"I welcome the new rule so much. It is such a wonderful rule that gives my son enough time for breakfast, which is necessary for his health and growth", a mother named Xu Li said. She is from Hangzhou and his son is in Grade 1. These changes have received much praise as they make students get enough sleep and enough time for breakfast.

Pushing back school times isn't unique (唯一的) to China. In the United States, schools in at least 21 states began to start school later in 2017, as studies have shown that later school start times could be good for students' development.
