Q28:

In an effort to reduce the number of fires started by cigarettes, a major tobacco company is test-marketing a cigarette in which thin layers of extra paper are used to decrease the amount of oxygen entering the cigarette, thereby slowing the rate at which it burns and lowering the heat it generates.

A.      in which thin layers of extra paper are used to decrease the amount of oxygen entering the cigarette, thereby slowing

B.       in which they use thin layers of extra paper in decreasing the amount of oxygen entering the cigarette, which slows

C.       that uses thin layers of extra paper to decrease the amount of oxygen when it enters the cigarette, thereby slowing

D.      for which thin layers of extra paper are used to decrease the amount of oxygen that enters the cigarette, and thereby slowing

E.      using thin layers of extra paper in decreasing the amount of oxygen entering the cigarette, which slows

答案是A，我选的是E

还是搞不大清楚，定语从句和现在分词引导的句子的区别

LZM上好像说是现在分词在表伴随的时候有优势，但是这题上也没有体现太多

这题应该不涉及到现在分词和定语从句的细微差别,关键点是逻辑主语。

看到现在分词,马上要想它的逻辑主语是谁?是否有逻辑主语?如有，这个逻辑主语合适不合适?SC中大多数分词的错误都是无逻辑主语或逻辑主语不合适.

E中using这个动作，显然不是其前面的名词cigarette能发出的,所以排除掉了.

which不能表示一件事；it 可以，但是也不是很好

请问C错在哪里啊？

that=in which吧

snowofjune

偶也选了C，当时排除A认为主动优先于被动。没想到错了

solmyr

同问，我也觉得C没错，没有用被动反而优于A。请NN赐教。。。

blogfish

同问C，难道是when it这个“it”指代不清么？

丸子宝宝

我觉得 C中的 it 应该指代 the cigarette，于是就不对了。。

C 还有一个错误是 uses 的语法主语是 cigarette, 但 uses 的逻辑主语应该是 tobacco company。

A.in which thin layers of extra paper are used to decrease the amount of oxygen entering the cigarette, thereby slowing（which指代a cigarette;be used to do; entering 作后置定语修饰oxygen；thereby slowing和未划线后句的and lowering平行作伴随状语修饰前句，表结果）

B.in which theyuse thin layers of extra paper in decreasing the amount of oxygen entering the cigarette, which slows（they无指代；use sth in doing错；which slows的先行词不明确，可能是cigarette，也可能是前句，易产生歧义）

C.that uses thin layers of extra paper to decrease the amount of oxygen when it enters the cigarette, thereby slowing（when引导时间状从修饰oxygen，但逻辑上意思变成了当氧气进入烟时才减少它的量，错）

D.for which thin layers of extra paper are used to decrease the amount of oxygen that enters the cigarette, and thereby slowing（for介词意思错；and在语法上连接is test-marketing与slowing和后面的lowering，但逻辑上后两者不是烟草公司的行为，而是其结果，所以应用伴随状语）

E.using thin layers of extra paper in decreasing the amount of oxygen entering the cigarette, which slows（use sth in doing错；which slows的先行词不明确，可能是cigarette，也可能是前句，易产生歧义）
