有以几个题，希望XDJM们能帮忙，多谢大家。
【1】Several years ago the diet industry introduced a variety of appetite suppressants, but some of these drugs caused stomach disorders severe enough to have them banned by the Food and Drug Administration.
(A) stomach disorders severe enough to have them
(B) stomach disorders that were severe enough so they were
(C) stomach disorders of such severity so as to be
(D) such severe stomach disorders that they were
(E) such severe stomach disorders as to be
新东方答案为D，我认为E是正确答案。

【2】Tiny quantities of more than thirty rare gases, most of them industrial by-products, threaten to warm the Earth’s atmosphere even more rapidly than carbon dioxide during the next fifty years.
(A) to warm the Earth’s atmosphere even more rapidly than carbon dioxide during the next fifty years
(B) to warm the Earth’s atmosphere even more rapidly over the next fifty years than carbon dioxide will
(C) during the next fifty years to warm the Earth’s atmosphere even more rapidly than carbon dioxide
(D) a warming of the Earth’s atmosphere during the next fifty years even more rapid than carbon dioxide’s
(E) a warming of the Earth’s atmosphere even more rapid than carbon dioxide’s will be over the next fifty years
Why B not A?对于B，我有两个疑问： 1) “over the next fifty years”的位置有点不对吧？2）按照这个短语的位置应该threaten to warm...用将来时才对呀？

【3】Out of America’s fascination which all things antique has grown a market for bygone styles of furniture and fixtures that is bringing back the chaise lounge, the overstuffed sofa, and the claw-footed bathtub.
完整的正常语序是什么？我怎么就不知道which all things atique后面应该是什么。

【4】OG-89：89. A recent national study of the public schools shows that there are now one microcomputer for every thirty-two pupils, four times as many than there were four years ago.
(A)there are now one microcomputer for every thirty-two pupils, four times as many than there were
(B)there is now one microcomputer for every thirty-two pupils, four times as many than there were
(C)there is now one microcomputer for every thirty-two pupils, four times as many as there were
(D)every thirty-two pupils now have one microcomputer, four times as many than there were
(E)every thirty-two pupils now has one microcomputer, four times as many as
official guide说Choices D and E reorder and garble the "one X ..." construction, making four times as many refer illogically to pupils，DE中的four times…为什么不修饰microcomputer,而修饰pupils?另外一个问题：下面的用法哪些对，every 32 pupils has one microcomputer; every 32 pupils have one microcomputer?

【5】以下的用法，谁对谁错？
the stone is too heavy to move
the stone is too heavy to move it
the stone is too heavy to to be moved

【6】The guiding principles of the tax plan released by the Treasury Department could have even a greater significance for the economy than the particulars of the plan.
(A) even a greater significance for the economy than
(B) a significance that is even greater for the economy than
(C) even greater significance for the economy than have
(D) even greater significance for the economy than do
(E) a significance even greater for the economy than have
新东方答案为D，我有个问题：为什么助动词不用could，而用do？

【7】The proposed urban development zones do not represent a new principle; it was employed in "Operation Bootstrap" in Puerto Rico.
(A) do not represent a new principle; it
(B) represent not a new principle, but one that
(C) are not a new principle; the same one
(D) are not a new principle, but one that
(E) are not new in principle; it
新东方答案B。why B not D?我认为“represent not a ...”的否定好像有些问题吧？

【8】Although fruit can no longer grow once it is picked, it continues for some time to respire, taking in oxygen and giving off carbon dioxide, similar to the way
human beings breathe.
(A) similar to the way human beings breathe.
(C) just like the breathing of human beings
(E) just as human beings do when they breathe[why do?]
新东方答案为E,我觉得AC好像也对，况且E中的助动词使用do，前面部分使用的是现在分词，好像也不太对劲呀？大家看看。

【9】Although it claims to delve into political issues, television can be superficial such as when each of the three major networks broadcast exactly the same statement from a political candidate.
(A) superficial such as when each of the three major networks
(B) superficial, as can sometimes occur if all of the three major networks
(C) superficial if the three major networks all
(D) superficial whenever each of the three major networks
(E) superficial, as when the three major networks each
why E not C? 我觉得E有重复：as and when，一个足以。

我在此先多谢各位XDJM了。

1、so as to前后的主语要一致哎
2、是因为助动词尽量补出原则
3、Out of America’s fascination 是主语，has是谓语，可能当中省略了

猫猫头

5、第一个最好，第二个不对，第三个在GMAT中肯定是不简洁的表达方式

猫猫头

6、could在这里表示的是一种虚拟语气，而后面不需要表达虚拟
7、有这种表达方式的

猫猫头

8、这道题目主要是把它的逻辑关系搞清楚了，你就不会觉得AC对了^_^
9、as表示正如。。。而when表示当。。。

多谢斑竹。第一题本来D答案中的they不就是指主语"some of these drugs"么？

猫猫头

我觉得代词一般优先指代句子的主语比较多，但也不一定的

猫猫：
     关于这题，我有疑问：
【5】以下的用法，谁对谁错？
the stone is too heavy to move
the stone is too heavy to move it
the stone is too heavy to be moved
是否第三个更好呢？
见下题：
这是一个正确选项
(A)infrared radiation, however, is invisible because its wavelength--0.1 millimeters--is too long to be registered by the eye

猫猫头

一肯定是很正确的表达方式，我们从小就这么说的呀
不过三也不错，你的那个题目可能是要强调施加动作的那个eye所以在这里要用被动吧

vin0410

the stone is too heavy to move
可以是for us to move吧, 也许要视句意而定
