SC题目！【XDF书里的题囧】求解答啊！！

小明白的囡囡

各位大神求解答！！

新手实在是。。。

这次问题有点多，虽然还是一样的chun

1. Since the 1930’s aircraft manufacturershave tried to build airplanes with frictionless wings, shaped so smoothlyand perfectly that the air passing over them would not become turbulent.

(A) wings, shaped so smoothly and perfectly

(B) wings, wings so smooth and so perfectlyshaped

(C) wings that are shaped so smooth andperfect

(D) wings, shaped in such a smooth andperfect manner

(E) wings, wings having been shapedsmoothly and perfectly so

选了D ，正解是B。

为什么D不对呢？

如果说是因为smooth和perfectly shaped是并列修饰wings，那么我要是再做一遍这题，估计还是看不出来……

2.When rates were raised in 1985, postalservice officials predicted they would make further rate increasesunnecessary for at least three years.

(A) they would make further rate increasesunnecessary

(B) they would mean that further rateincreases would not be needed

(C) that it would not be necessary forfurther rate increases

(D) that the increase would make furtherrate increases unnecessary（D）

(E) further rate increases will not beneeded

答案是D, 我选了A

因为看到D里面有好多increase就直接放弃了，感觉太过冗余。

知道正解后，依然不能理解，什么叫“在未来至少三年，增长会使更多增长没有必要”……原文的意思不是说“会有更多不必要的增长”么？

还有一点就是，我记得XDF说过，宾语从句要加that, 那么我可以接受CD。是有这样的说法吗？

3.According to his own account,Frederic-Auguste Bartholdi, the sculptor of the Statue of Liberty, modeled theface of the statue like his mother’s and the body like his wife’s.

(A) modeled the face of the statue like hismother’s and the body like his wife’s

(B) modeled the face of the statue afterthat of his mother and the body after that of his wife

(C) modeled the face of the statue like hismother and the body like his wife

(D) made the face of the statue after hismother and the body after his wife

(E) made the face of the statue look likehis mother and the body look like his wife

正解是B，我选了E。

感觉A也是对的，为什么不能用like呢？

4.A huge flying reptile that died out withthe dinosaurs some 65 million years ago, the Quetzalcoatlus had a wingspan of36 feet, believed to be the largest flying creature the world has ever seen.

(A) believed to be

(B) and that is believed to be

(C) and it is believed to have been

(D) which was, it is believed,

(E) which is believed to be

正解C,我选B

why not B??!?!!!

何必要用have been 呢？？

5、The guidingprinciples of the tax plan released by the Treasury Department could have evena greater significance for the economy than the particulars of the plan.

(A) even a greater significance for theeconomy than

(B) a significance that is even greater forthe economy than

(C) even greater significance for theeconomy than have

(D) even greater significance for theeconomy than do

(E) a significance even greater for theeconomy than have

正解D,我选了E

现在知道E，significance 不可数。

疑问在于选项最后，补助动词的时候，主句中是could have …这种情况算是哪一类啊？为什么用do?

下面是网上查到的说法，我表示没有怎么理解。

（“考察比较中的省略结构。

也就是than后面到底是没有助动词，还是加do,或者是have。首先than后面如果有助动词的话，必然是事情和事情的比较，也就是句子间的比较，如果没有助动词就是than前后名词的比较。Do 和have的取舍在于前面的时态，如果前面是一般时态就用do的形式，如果前面是完成时就用have的形式。

这里很显然是事情和事情的比较（principles 和particulars各自have significance的比较）所以需要助动词，因为前面是一般时态，所以用do,选择D

另外，significance是不可数名词。”）

The guidingprinciples of the tax plan released by the Treasury Department could have evena greater significance for the economy than the particulars of the plan.
(A) even a greater significance for theeconomy than
(B) a significance that is even greater forthe economy than
(C) even greater significance for theeconomy than have
(D) even greater significance for theeconomy than do
(E) a significance even greater for theeconomy than have
用do不用have主要是因为重复了have这个词，所以用do,当然用动词原型是因为前面有could所以have就是原型。
具体可以参见国外论坛讨论

4.A huge flying reptile that died out withthe dinosaurs some 65 million years ago, the Quetzalcoatlus had a wingspan of36 feet, believed to be the largest flying creature the world has ever seen.
(A) believed to be
(B) and that is believed to be
(C) and it is believed to have been
(D) which was, it is believed,
(E) which is believed to be
很少用that做代词，所以B不好
C中have been和后面的has ever seen的时态保持一致，意思是，从发现开始到现在都是最大的balabala,没有超过它的新发现

1. 选项 D 导致整个句子无主语。 因为句子是以 since 开头，所以逗号后面必须出现主语

2. A 和 B 选项里面的 they 指代不清， 可以指代 rates, 也可以指代 officials。 C 选项 it 指代不清。我觉得 D 选项之所以是正确答案，可能是因为句子里面主谓宾结构很完整，句子表达明确，没有歧义。

the increase (happened in1985) would make further rate increases (in the future) unnecessary

3. 这道题我觉得是考察 ”like“ 的用法吧。记得有道GMAT语法题解析里面说，”like“ 在GMAT里面出现，只能用作 “喜欢” 的意思。 “像“ 这个意思会用 ”as“。 这道题我也不确定，希望有NN来解释一下~

4、5 题我也看晕了。。

3.According to his own account,Frederic-Auguste Bartholdi, the sculptor of the Statue of Liberty, modeled theface of the statue like his mother’s and the body like his wife’s.

(A) modeled the face of the statue like hismother’s and the body like his wife’s

(B) modeled the face of the statue afterthat of his mother and the body after that of his wife

(C) modeled the face of the statue like hismother and the body like his wife

(D) made the face of the statue after hismother and the body after his wife

(E) made the face of the statue look likehis mother and the body look like his wife

此处考词语搭配 model after是仿照…制作的意思，所以A,C不对，排除。
model after和made比较，model after的语义贴切，D,E排除。
这种直接考察词汇的题目，要是对于词汇的使用不熟悉，还是很容易出错的。

1. Since the 1930’s aircraft manufacturershave tried to build airplanes with frictionless wings, shaped so smoothlyand perfectly that the air passing over them would not become turbulent.

(A) wings, shaped so smoothly and perfectly

(B) wings, wings so smooth and so perfectlyshaped

(C) wings that are shaped so smooth andperfect

(D) wings, shaped in such a smooth andperfect manner

(E) wings, wings having been shapedsmoothly and perfectly so

重点在于修饰对象不清，A和D可以修饰manufacture也可以是with后面的wings，排除。
C 在于smooth和perfect不是副词，排除
E so的位置奇怪，时态也奇怪，排除
所以选择B

2.When rates were raised in 1985, postalservice officials predicted they would make further rate increasesunnecessary for at least three years.

(A) they would make further rate increasesunnecessary

(B) they would mean that further rateincreases would not be needed

(C) that it would not be necessary forfurther rate increases

(D) that the increase would make furtherrate increases unnecessary（D）

(E) further rate increases will not beneededC和D是predict 引导的虚拟语气(当然也是宾语从句)，所以最好有that(但是查了一下国外论坛，在非正式的场合that也不是一定不能省略)
D问题是It's necessary for 需要加 sb.或者和人相关的，rates不符合,排除
C的语义表达更清楚，不容易引起歧义，但是在不知道正确答案的情况下，很难区分到底应该是哪种语义，所以这个方法不太实用。我认为此题重点在于代词指代，A,B中they指代不清，不知是rates还是officials,排除。
E时态不对，predicted 后面不该用will，排除

另外，宾语从句不一定必须+that，另外GMAT这种考试不到万不得已，我不建议你用背规则的方法来做题，因为太灵活了。
