一周后考试。几个语法点恳请指点！！

liuchang1988

1, a reason why的用法有没有重复？

2,since是不是只能跟现在完成时，不能跟过去完成时（had done)?

3,what在什么情况下能替代that做引导词呢？

4,while的用法能不能详细叙述一下！

5,there be a and b的be是不是根据a的单复来决定？

感谢！

我来回答几个我懂的吧，呵呵。

1、没有重复：The reason why people don’t use their telescopes is they are such a pain to haul out and set up.

2、可以跟过去完成时:

The advance occurred two weeks after a local pro-government leader died of a heart attack. The leader, Mullah Naqibullah, had prevented the Taliban from entering the Arghandab area since 2001 and had survived repeated assassination attempts.

3、不记得what还能代替that的，似乎只能代替all that

4、while能做连词，表示as long as, 还表示whereas

5、对

The advance occurred two weeks after a local pro-government leader died of a heart attack. The leader, Mullah Naqibullah, had prevented the Taliban from entering the Arghandab area since 2001 and had survived repeated assassination attempts.

3、不记得what还能代替that的，似乎只能代替all that

4、while能做连词，表示as long as, 还表示whereas

不对的地方请NN指出！

谢谢。

但PREP笔记第三题的解释里说since不能跟过去完成时。求助NN！！

再补充几个问题。现在分词在句尾，到底是修饰前面句子的主语还是宾语呢？ N1,N2 and N3,which...这个which指N3还是全部的呢？  until recently是不是必须跟完成时而不能跟一般过去时？

有没有具体的例子拿出来看看呀?

since 是没有见到跟过去完成时的,那个题目也可以换个思路

主过完,从过完错误

1， a reason that > a reason why, but both are correct

2,  since 是现在完成时态的标志 不能跟过去完成时

3，区别很大

that 主要是引导修饰句子某一成分的（如定语从句或宾语从句）

what本身就可以是名词性的 用来取代句子中的某一成分（如 主语、宾语）  

我没有见过两者可以替换的

4，While

A  作为转折连词，
            通常是比较非书面的 （GMAT中好像没有作转折连词的正确的例子）

B  While 既可以引导从句, 也可以引导分词的省略形式 例子在这里有

since 有时候可以跟过去完成时的，具体要看题目的意思。我举的这个例子是从New York times上面找来的 . 这个句子的情况比较特殊，因为这个leader已经死了，用现在完成时显然不对。Anyway， since跟现在完成时的还是大多数。

until recently 可以跟一般过去时的，我记得OG有一题的，忘记题号了。楼主如果不确定某些英语的正确用法，建议用google搜索一下。New York Times的英语很标准很地道的，你只要在关键字的地方输入 "AAA" site:www.nytimes.com 就可以google出 AAA的正确用法了。

关于那个which，我记得是就近指代优先，但是也不排除越前指代的可能。反正两种情况我都在GWD里面见过。

liuchang1988

谢谢各位啦！！GWD确实歧义有点多~~不过也有助于分析错误~

补充第三点

What = the thing that = that which
