6.Because paper of all kinds is the biggest single component of municipal trash, many municipalities have tried recycling to reduce the cost of trash disposal.
(A) Because paper of all kinds is the biggest single component of municipal trash, many municipalities have tried recycling to reduce the cost of trash disposal.
(B) Because paper of all kinds is the biggest single component in municipal trash, many municipalities tried to recycle so that the cost of trash disposal is reduced.
(C) Because paper of all kinds are the biggest single components in municipal trash, many municipalities have tried to recycle to reduce the cost of trash disposal.
(D) All kinds of paper are the biggest single components of municipal trash, and so many municipalities have tried recycling to reduce the cost of trash disposal.
(E) All kinds of paper is the biggest single component of municipal trash, so many municipalities have tried to recycle so that the cost of trash disposal could be reduced.
the key:A.帮我看看我的想法是否正确：
根据主谓一致的原则排除C和D(all kinds of+n.做主语谓语动词的单复数应该由of后面n.的单复数来决定的，对吧？)。
根据is reduced可以判断B选项中tried的时态错误。
E选项明显不如A简洁。所以选A。对不对？
还有个问题，好像在GMAT语法中不止一次出现and so结构，这里的so是不是应该理解为adv.
根据m-v词典
so adv.THEREFORE, CONSEQUENTLY （the witness is biased and so unreliable）
多谢了！

and so表示并列因果
顺便的说E中的错误不少呢，try doing 和 try to / could be reduced, 我认为都是错误。

solome,你的意思是and so这是个词组，合起来表示并列因果？
could be reduced的时态的确有错误
不过，你说的try doing和try to 也有错误是什么意思哟，细说一下？

嗯，是呢

另外，郎文：

He tried to climb the mountain (= but he couldn’t)
He tried climbing the mountain. (= he climbed it, to see what it was like )]

这个是区别呢

谢谢solome，明白了。不过这个try to 与try doing的区别我还是第一次听说呢，见笑了！我脑袋中从来把它们俩划等号的，赫赫

问题：1，all kinds of paper 与paper of all kinds 的区别，什么地方看到过，忘了，？
     2，新东方光盘上说all kinds of paper 与paper of all kinds 都带单数主语 is对吗？谢谢！

1，重心不同，all kinds of paper 核心词是all kinds，强调多种多样；paper of all kinds 强调  paper 意思也随之有点差异。

   2，paper of all kinds 肯定加is
        all kinds of paper 按照ecsniffer MM 说的原则：all kinds of+n.做主语谓语动词的单复数应该由of后面n.的单复数来决定的，那也应该加is
       呵呵，ecsniffer MM 又教了我一个知识点了~~~谢谢！！

还有个问题请教各位. 在选项B和E中的recycle用作动词,可是后面不接宾语, 总觉得很不舒服. 我查了一下字典, M-W说recycle有不及物动词, 可是没有例子; 金山词霸给的解释只有及物动词. recycle后面不接宾语这样的用法究竟对不对呢?

另外, 从语感上来说try doing to do是肯定对, 翻译成"试图作某件事而达到...目的", 可是C选项中这样用try to recycle to reduce...读起来很别扭, 不知道这样的用法是否正确?

读的是不爽，但是词性上讲似乎没问题

have tried recycling to reduce the cost of trash disposal.
原题想要表达得是  尝试通过做某事来达到某种目的，即尝试通过recyling 去reduce cost.
recycling 是一种途径，to reduce ....是想要达到得目的，从句意理解会好一些。
