.they also need to understand what changes could be made to air pollution sources that cause the prolem（这句话不会翻译.）
好像还有that be .额 ,
他们也需要了解对于空气污染有什么样的变化that cause the problem。
全句是
to solve the acid rain problem,people need to understand how acid rain cause damage to the environment .they also need to understand what changes could be made to air pollution sources that cause the problem.
翻译好解决点就先说下翻译了：they also need to understand what changes could be made to air pollution sources that cause the problem.他们同时得知道怎样的改变可能会变成造成这个问题的空气污染源主句是 the...Idon't think that doing exercise is usefu我觉得这句里的that应该只是从句标志，doing exercise是主语 与that没有关系。that matters a lot for me这句跟我问的像。it is a table that made of wood 这个是that done 强调被动I think that doing lots of listening 这个是个that doing吧？I think that doing lots of listening 这不是一个合语法的句子，that 引导的宾语从句中成分不足，即没有最基本的主谓。 I think that doing lots of listening is good 才合理，不过这样的话又跟上面的一样，that 只是个不做成分的关系代词，在这里可以省略。 在这里抱歉！it is a table that made of wood 这个句子是错误的！It is a table that is made of wood 才对。表示被动的Be动词不能省略。 这样的话应该是没有 that done 这个结构的吧。。。。。或者跟后面的东西有关，比如 that ruined house belongs to me 那个毁坏的房子属于我。 这里的done 结构的 ruined 死过去分词做形容词修饰 house的，跟that 无关。。。。天哪。。。。。。。难道，那些年我都是错过来的。我也不知道楼主哪里来的印象这样组合的 = =！；其实除去做关系代词的时候，楼主可以把that 简单地看做一个名词，即指代的那个东西就好了。名词怎么用，that 就怎么用。都是具体情况具体分析的。。。。。。。
