GWD 补充题 24-23

24-23 Discussion of greenhouse effects has usually focused on whether the Earth would warm and by how much, but climatologists have indicated all along that the most obvious effects, and those that would have the largest impact on people, would be extremes of temperature, precipitation, and storminess.

A) the most obvious effects, and those that would have the largest impact on people, would be extremes of temperature, precipitation, and storminess.

B) the effects that are the most obvious ones, extremes of temperature, precipitation, and storminess, would be those impacting the most on people.

C) those effects to have the largest impact on people, extremes of temperature, precipitation, and storminess, are what are the most obvious effects.

D) extremes of temperature, precipitation, and storminess, the most obvious effects, that they would have the largest impact on people.

E) extremes of temperature, precipitation, and storminess, which are the most obvious effects, are those to impact the most on people.

The key "A" totally doesn't make any sense.

The "and" is within the scope of the subclause, what the hell this "and" is parallel to? If "and" is taken out, it will make much more sense.

---that the most obvious effects, those that would have the largest impact on people, would be extremes of temperature, precipitation, and storminess

If there's no typing problem, i rather choose B.

"those that would have the largest impact on people" doesn't mean to indicate "the most obvious effects",  hence the words below mean two different things, A and B.

"the most obvious effects, and those that would have the largest impact on people"

of course,  maybe there are some overlaps among the two.

For example, a similar sentence is:

In our group , the young and the restless are Michael, Peter, and Cindy.

If it's the case of compound subjects, comma is not justified here. It shoud be:

"the most obvious effects and those that would have the largest impact on people would be extremes of temperature, precipitation, and storminess"

这里是插入语

虽然A最好，但你说的好象也有些道理， 晕！  NNS 显身吧~~

我的异议在于would的使用，would在这里容易引起异议，这里说的是科学家显示，显然是客观存在的东西，而would表明了这种显示是不正确的-是一种猜想也可能是真的

请大家指正

B ）the effects that are the most obvious ones, extremes of temperature, precipitation, and storminess, would be those impacting the most on people.

变成了the most obvious ones, extremes of temperature, precipitation, and storminess并列了，不合句子原来的意思。

A is still your best choice.

the most obvious effects, and those that would have the largest impact on people, would be extremes of temperature, precipitation, and storminess.

and those ... on people 是插入语，and 表示额外的effect; 如果去掉and, those that .... 修饰前面的obvious effects,

成了同位语，改变了句意。

除了E中sth is sth to do的结构以前没注意过,不知道对不对外, E算是很好的答案了(我搜了google, 确实有这样的句子)

其它的都有非常明显的错误.
