这四道题 连着做 对比一下 就晕了 不知道什么时候 more than 对比的时候 就要 补全句子 主语 什么时候不需要的
一、187.(GWD-1-Q32)
To develop more accurate population forecasts, demographers have to know a great deal more than now about the social and economic determinants of fertility.
A.have to know a great deal more than now about the social and economic
B.have to know a great deal more than they do now about the social and economical
C.would have to know a great deal more than they do now about the social and economical
D.would have to know a great deal more than they do now about the social and economic(D) 如这个题 more than 后面是 补全主谓语的
E.would have to know a great deal more than now about the social and economic
题目释义：To develop…, demographers would have to…more than now they do about…
考点：
比较结构
选项分析:
(A)a great deal与now比较(than后面只有一个成分now，所以a great deal只有与其进行对比)，概念不对等ànow作为状语没有与其平行的副词，所以than后面需要有成分能够与a great deal平行，一个好的解决方法是than后面补出主谓，使than前后形成句子的平行，补出谓语的原因是使比较对象没有歧义。
(B)economic的意思是：relating to trade, industry, and the management of money，而economical为便宜or节省的意思，根据逻辑含义应该用economic。
(C)economical使用错误。
(D)Correct；本句使用would have to还是have to都可以(详见补充说明)。
(E)a great deal与now比较，概念不对等。

大全10.A large rise in the number of housing starts in the coming year should boost new construction dollars by several billion dollars, making the construction industry’s economic health much more robust than five years ago.
(A) making the construction industry’s economic health much more robust than five years ago
(B) and make the construction industry’s economic health much more robust than five years ago
(C) making the construction industry’s economic health much more robust than it was five years ago
(D) to make the construction industry’s economic health much more robust than five years ago
(E) in making the construction industry’s economic health much more robust than it as five years ago
Key: C
类似例句：
The animosity between those who regulate and those who are regulated has never beenmore pronouncedthan in recent debates over environmentalism and pollution control.
这个例句中never与in recent debates相对应。
三、189.(GWD3-Q30) (旧Prep2-131)
Today’s technology allows manufacturers to make small cars more fuel-efficient now than at any time in their production history.
A.small cars more fuel-efficient now than at any time in their
B.small cars that are more fuel-efficient than they were at any time in their
C.small cars that are more fuel-efficient than those at any other time in
D.more fuel-efficient small cars than those at any other time in their(C) 但这个题 就只有those 不用 they were？
E.more fuel-efficient small cars now than at any time in
²more [fuel-efficient small cars]：词组的核心意思是更多的车，而这些车是经济省油的
²[more fuel-efficient] small cars：更经济省油的小车
选项分析:
(A)比较的是时间状语，比较对象变成now和at any time，现代科技能使小车”在现在比在过去”省油，语义存在逻辑错误；today和Now重复；at any time没有将自身排除在外，应为any other time；their指代不明，逻辑上指代cars，可语法上更倾向于指代manufacturers。
(B)that are more fuel-efficient虽然表达比较繁复，但使意思清楚，没有歧义；they指代cars that are more fuel-efficient(包括small cars的修饰词)，表达了前后是同一批cars，既出现在现在，还要出现在任何生产史的阶段，应该用those来指代前面的cars（those为核心词指代）；at any time没有将自身排除在外，应为any other time；their指代不明同A。
(C)Correct；that are more fuel-efficient虽然表达比较繁复，但使意思清楚，没有歧义；those合理的指代了cars，使比较对象对等；at any other time排除了比较的另一段—today，合理；该题目句子合理的意思应该是，现在造出的车，比汽车生产史上其它任何时候造出来的车要更省油；比如说，2005年造出来的车子比2004年造出来的车子省油。而不是某一既定的车子在现在比在过去省油，打个比方说，不应该是某辆车子A在2005年比在它在2004年省油。在构造这个句子时，我们一定要注意这一点，避免形成类似的歧义/逻辑错误。避免这种错误的方法在于，保证句子是名词或代词cars/those之间的比较，而不是表时间的副词或介宾语词组的比较。smallcars that are more fuel-efficient than…这种定语从句结构是没有歧义的。
(D)more fuel-efficient small cars造成adj修饰歧义：more既可修饰fuel-efficient，也可修饰cars；their问题同A。
(E)more fuel-efficient small cars造成adj修饰歧义：more既可修饰fuel-efficient，也可修饰cars；比较对象变成now和at any time；at any time没有将自身排除在外，应为any other time。
四、197.(GWD-1-Q16) Soaring television costs accounted for more than half the spending in the presidential campaign of 1992,a greater proportion than it was in any previous election.
A.a greater proportion than it was
B.a greater proportion than 这个也没有补全 主谓语啊？？
C.a greater proportion than they have been
D.which is greater than was so(B)
E.which is greater than it has been
题目释义：Soaring television costs accounted for … half the spending in the presidential campaign of 1992, a greater proportion than in any previous election.
Soaring television costs主语，accounted for谓语，a greater proportion为同位语，修饰前面整个名词短语。
考点： 指代一致（Agreement）
1.which就近指代名词，不能指代完整的一句话；
2.it在文中，会继承被指代对象的特性，业即本文中，it 如果指代 a great proportion或者 the spending ，都继承了a great proportion或者 the spending 发生在presidential campaign of 1992的特性，造成比较的逻辑关系错误，要引以注意。
(B)Correct；原句补完整：Soaring television costs accounted for more than half the spending in the presidential campaign of 1992, a greater proportion than（the proportion）（television costs had accounted for of the spending）in any previous election；这个句子中只是单个名词(proportion)的比较，所以不需要考虑than后面补出主谓，只补出介词短语就够了，不用担心后面的介词短语in any previou election没有平行对象
(C)现在完成时使用错误，in any previous election说明应用过去完成时；they指代soaring television costs，使逻辑意义错误，比较结构需要比较对象对等，前者为a great proportion 是一个量词不能和具体的费用对比，而且其他的election不一定是soaring的；同时have been与前面的accounted for不平行，只要也要用have done。
(D)Which不能指代前面整个idea；so用于省略重复的动作，使用错误。
(E)Which不能指代前面整个idea；it指代不清，且has been时态与后面的in any previous election不符。
类似例题链接： OG10- 198. Although Napoleon's army entered Russia with far more supplies than they had in their previous campaigns, it had provisions for only twenty-four days.
(A)they had in their previous campaigns
(B)their previous campaigns had had
(C)they had for any previous campaign
(D)in their previous campaigns
(E)for any previous campaign 同样只有 介词的比较 为什么这里就不存在 more than 前后比较 不对称 的关系了呢？ If than is followed by a clause referring to army, the subject of that clause must be singular (it). Furthermore, the verb of that clause will need to be in the past perfect form (had had) because it refers to a time beforethe simple past of entered. Finally, the prepositionforis more precise than in because supplies are gathered for an upcoming campaign. Choices A and C incorrectly use the plural theyand the simple past had. Moreover, A uses the less precise in.Choices D and E wisely dispense with the full clause and use a simple prepositional phrase. D, however, uses the imprecise in and the plural their. Only E, the best choice, avoids all the errors mentioned above.
