求证大全885section 20-6的思路

weiyu

本题关键：


1. try to do sth努力做...    ;     try doing尝试做...


2. all kinds of+n+verb(和n匹配)

jnlvo

好像反了吧：


try to do 试做...例：He tried to climb the tree, but he could not. 他试图爬树，可爬不上去。


try doing     努力做...    如本题：市政一直在努力地这么做(recycling)为了省开销。

以下是新东方语法老师白勇的解释(我们不能appeal to authority)，望讨论


Try用法:try doing尝试做…; try to do努力做…; all kinds of paper are错/is对

觉得其实solome提供的朗文上的解释已经比较清楚了。

以下是引用ecsniffer在2003-12-8 9:47:00的发言：
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！

我记得上新东方时老师说paper是不可数n,所以做主语时谓语动词是单数；但all kinds of paper就成了很多种paper了，所以谓语动词该是复数呀。

paper of all kinds ---中心词是paper, 所以是is

all kinds of paper---中心词是all kinds ,所以是are.

不知道你说的“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”是哪里说到的语法点，我都有点困惑了。但我记得看过很多不可数名词后面谓语动词用单数，而加了kinds of 之后谓语动词就变复数的。

请指正，共同讨论。

我的理解，请指正。

kind of paper: 中心词是paper, 谓语用单数,
kinds of paper: 中心词是kinds, 谓语用复数,
all kinds of paper: 中心词是all, 谓语用单数.

总结一下题点：

1）try to d 努力做…; try doing尝试做…

2）all kinds of+n+verb(和n匹配)

我的问题：

All kinds of paper 和 paper of all kinds存在重心问题嘛？？？？

我怎么觉得是一回事啊

两个的中心词都是paper吧

请讨论

以下是引用dreadpower在2003-12-26 12:49:00的发言：
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！！

"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",有这个说法？  有没有根据啊？
