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

这题到底选a还是b啊？答案上选b 但我又搜到这样一段话：答案：A划线部分最后的slow应该是前面整句话发出的，所以应使用slowing，B和E的which无法指代前面整句话。C的it没有指代对象，D的and多余了，这里slowing是现在分词做伴随状语，没有必要使用and。
请高人指点啊！如果答案是B 那A错在哪里呢？！谢谢

GWD-12-Q2:

Scientists are discussing ways to remove excess carbon dioxide from the atmosphere by increasing the amount that is absorbed by plant life.One plan to accomplish this is to establish giant floating seaweed farms in the oceans.When the seaweed plants die, they will be disposed of by being burned for fuel.

Which of the following, if true, would indicate the most serious weakness in the plan above?

A.Some areas of ocean in the Southern Hemisphere do not contain sufficient nutrients to support large seaweed farms.

B.When a seaweed plant is burned, it releases an amount of carbon dioxide comparable to the amount it has absorbed in its lifetime.

C.Even if seaweed farms prove effective, some people will be reluctant to switch to this new fuel.

D.Each year about seven billion tons of carbon dioxide are released into the atmosphere but only about five billion tons are absorbed by plant life.

E.Seaweed farms would make more money by farming seaweed to sell as nutritional supplements than by farming seaweed to sell as fuel.

B错在哪里？答案A只是说某些区域不能搞seaweed farm啊相比之下不是B 更严重一些么？

第一道，应该选A吧。B选项的they, 也没有指代对象啊

第一道应该是A，B的话，which是不能指代整个句子的

uupigyu318 · 发表于 2010-11-9 16:35:05

slowing 和lowing 是平行修饰句子的吧？？

B中最后那个which 错误无法指代前面一句话
如果是指代cigarette 明显不符合逻辑

第二题应该选B，本文的topic是remove excess carbon dioxide，B选项正好说明seaweed is burned释放的carbon dioxide与吸收的量相当，起了消弱作用。
