GWD24-23

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.

KEY:A

I don't understand the structure of "A"

Hope somebody give me some advice!

Thanks!

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

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

24-23. Discussion of greenhouse effects has usually focused on whether the Earth would warm and by how much, but(前後對比) climatologists have indicated all along that(引導後面子句) the most obvious effects, and those(most obvious effects) that would have the largest impact on people(插入句可忽略), (most obvious effects)would be extremes of temperature, precipitation, and storminess(and 並列三個).

總的來說就是but 前後各是一個主句帶一個從句，前後句意約略相反

thanks!!!!!!

这题中and those...插入语的结构跟OG64完全一样！

40.   In metalwork one advantage of adhesive-bonding over spot-welding is that the contact, and hence the bonding, is effected continuously over a broad surface instead of a series of regularly spaced points with no bonding in between.

(A) instead of
(B) as opposed to
(C) in contrast with
(D) rather than at（D）
(E) as against being at

You are right~

and those恐怕不应该理解为插入吧。上例是and hence,就好比我们写AA,AI是使用的and thus一样，表示递近意思的并列啊！

个人认为这里的and就是and，不是和those一起的，开始我也认为这里的and用的不对，但重新考虑整句的意思，发现的确两个主语并列.两者可能一致,也可能不一致,合并构成从句的主语.[明确的名词,和可能的限定,使两个表述的内容可能不同,因此可以并列,并不重复]
