[求助]紫草姐姐“前三后三”法

转自：http://forum.chasedream.com/dispbbs.asp?boardID=34&ID=129392&page=3

考试时候的方法就是前3词, 尾3词, 再中间. 很多题目都可以靠这6个词解决, 大概只要20秒, 因为分别2/3split以后就只剩下一个了. 下面我举一个比较有代表性的例子:

GWD24-13

Vivien Thomas, who had no formal medical training, in struggling against overwhelming odds, he became a cardiac surgeon and eventually to receive an honorary doctorate from Johns
                Hopkins
                University.

A) who had no formal medical training, in struggling against overwhelming odds, he became

B) having had no formal medical training, in struggling against overwhelming odds to become

C) who, having no formal medical training, he struggled against overwhelming odds in becoming

D) who, having had no formal medical training and struggled against overwhelming odds, became (E)

E) who had no formal medical training, struggled against overwhelming odds to become

这道题上来就可以用having排除BCD, 而A后面又重复主语引起一个新的句子(我把它称之为”主语缀述”). 这道题对我而言, 10秒之内就可以解决. 当然, 如果不放心, 仔细看可以发现A前半句的结构dangling, 但我不会过多纠缠, 一般如果能靠6词确定就move on, 不行再看中间. 我在考场上做的语法题, 特别是前面的, 都很长, 我基本上都在30秒解决 (前10题除外). 其实语法点就那些, again, 把信息简化. 看透出题思路, 靠排除
        对症下药. 当然, 这样的方法总会有例外, 但我觉得花再多的时间也许可以找出为数不多的错误, 但margin不高. 很幸运的是, 我考试的题目没有特别反常规的思路.

good luck!

??? why?

I guess nobody saw my question... it's in the post No. 5.

I'll try to answer my own question.

in the example choice C

who, having no formal medical training, he struggled against overwhelming odds in becoming

having 分词短语位置不好，可能做定语，可能做状语, it can modify the preceeding subject, or it can modify the following phrase. It is ambiguous so it's wrong.

What 紫草姐姐 didn't say is this underlying rule. Next when you see a participle (分词短语) in 主语和谓语之间, you can eliminate it without thinking further.

Correct me if I am wrong.
