Dear friends,
As we can see, the environment around us is getting worse other than better. Our life and health have affected greatly. The earth is our home, but we have a duty to take care of it, not only for ourselves but for future generations. Fortunate, more and more people have become aware of this problem. Many effectively measures have been taken by the government to deal with them.
As a student, I think we should do what we can improve the environment. First, go to school on feet or by bike as often as possible. Second, turn on the lights and other electrical appliances before leaving the room. Third, never throw rubbish here and there.
It’s time that we do something to protect our environment.other改为rather
答案：
(答案→)other改为rather
解析：
【小题1】other改为rather固定搭配rather than而不是；环境在变得更糟糕，而不是更好。
【小题2】have后面接been本句是一个被动语态，我们的生活和健康都收到影响。
【小题3】but改为and/so上下文之间存在着并列关系，地球是我们的家园，因此我们有照顾地球的责任。
【小题4】Fortunate改为Fortunately本句中使用副词Fortunately在句中作状语。
【小题5】effectively改为effectively后面有名词measures，故前面使用形容词effective修饰。
【小题6】them改为it这里的it就是指前面的this problem。
【小题7】can后面接to本句中的不定式to improve…做目的状语。
【小题8】feet改为foot固定搭配on foot步行。这里的on foot和by bike是并列关系。
【小题9】on改为off固定搭配turn off关闭，turn off the lights关灯。
【小题10】do改为should do/did本句是一个虚拟语气，it is time后面的宾语从句使用should+动词原形/过去式。
