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.
