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.

数九寒冬，人们就算窝在被子里都能感觉到寒意。然而，湖南岳阳一位生有四子一女的87岁老人，却因为子女之间发生赡养争议，被迫在儿子家的屋檐下露宿了近十天。请你根据材料，结合教材，谈谈我们应怎样孝敬父母？

    白求恩同志毫不利己专门利人的精神，表现在他对工作的极端的负责任，对同志对人民的极端的热chén______。每个共产党员都要学习他。不少的人对工作不负责任，niān______轻怕重，把重担子推给人家，自己挑轻的。一事当前，先替自己打算，然后再替别人打算。出了一点力就觉得了不起，喜欢自吹，生怕人家不知道。对同志对人民不是满腔热chén，而是冷冷清清，___________，_____________。这种人其实不是共产党员，至少不能算一个纯粹的共产党员。从前线回来的人说到白求恩，没有一个不佩服，没有一个不为他的精神所感动。晋察翼边区的军民，凡亲身受过白求恩医生的治疗和亲眼看过白求恩医生的工作的，无不为之感动。每一个共产党员，一定要学习白求恩同志的这种真正共产主义者的精神。
