Q20:

Researchers have announced that the magnetic fields emitted by one manufacturer’s security surveillance system, of which type there are 200,000 worldwide, can interfere with pacemakers and that this interaction can bring on missed or irregular heartbeats, nausea, breathlessness, dizziness, and even fainting.

of which type there are 200,000 worldwide, can interfere with pacemakers and that

of which, worldwide, there are 200,000 of that type, and which can interfere with pacemakers, and

of which type there are 200,000 worldwide, they can interfere with pacemakers and

200,000 of which type exist worldwide, interfering with pacemakers, and

200,000 of that type existing worldwide and can interfere with pacemakers, and

答案选D，为什么呢？此处interfering with pacemakers 做什么成分呢？

奇怪? the magnetic fields emitted by one manufacturer’s security surveillance system, 200,000 of which type exist worldwide, interfering with pacemakers. 谓语呢?

我支持A.

是啊，我选的也是a,想法和你一样，如果选择D，就会没有the magnetic fields的谓语了。是不是还有什么隐晦的地方没有看出来呢？

jandjshi · 发表于 2006-4-19 14:39:00

难道D中the magnetic fields and this interaction作主语? can bring做谓语? 那也太awkward了吧!

如果选D的话，似乎只能这样解释了

只有D最idiomatic,"2000" should be in front of " of which", "interfering" is present participle.

谢谢jandjshi和yhzh，我的一个朋友解释说：

首先排除ABC，因为OF WHICH这样的用法只会导致语义含混，相信你读起来也不太顺口吧，呵呵，D和E就好排除了。主要是个语感的问题。

可是我还是不大明白，此句的谓语是谁呢？

jandjshi · 发表于 2006-4-20 02:16:00

D不对. the magnetic fields emitted by one manufacturer’s security surveillance system, 200,000 of which type exist worldwide, interfering with pacemakers

两个硬伤. 1) 没谓语 2) interfering present participle 在句中修饰surveillance system. 而句子逻辑上看应该是修饰emitted, 动作分出者应是magnetic fields.

A: announced that X can interfere, and that Y can bring on - 句型工整对称. of which type there are 200,000 worldwide可不可以理解为介短提前?
