og11 Verbal 72 关于than的省略

snowmary

       The gyrfalcon, an Arctic bird of prey, has survived a close brush with extinction; its numbers are now five times greater than when the use of DDT was sharply restricted in the early 1970's. .

(A)  extinction; its numbers are now five times greater than

(B)  extinction; its numbers are now five times more than

(C)  extinction, their numbers now fivefold what they were

(D)  extinction, now with fivefold the numbers
                they had

(E)  extinction, now with numbers five times
                greater than

 

答案是A，但是为什么than后面可以省略its numbers were呢？不是说时态不同的话，than后面的主谓即使

是系表结构也不能省略嘛？例如大全299

299.Florida will gain another quarter-million jobs this year alone, many of them in high-paying fields like electronics and banking, making the state’s economy far more diversified than ten years ago.
(A) high-paying fields like electronics and banking, making the state’s economy far more diversified than
(B) high-paying fields like electronics and banking, and making the state’s economy far more diversified than its economy
(C) high-paying fields such as electronics and banking, to make the state’s economy far more diversified than
(D) such high-paying fields as electronics and banking, making the state’s economy far more diversified than it was（D）
(E) such high-paying fields as electronics and banking, and make the state’s economy far more diversified than it was

难道than后面是XXX years ago的时候就不能省，是一个when从句就可以省了嘛？

 

省略的题目都好头痛啊～

顶一下～NN们帮帮忙啊～

snowmary

没有人回答一下嘛～～

继续问～

The word 'when' is used to modify 'it' just like the other example.

when ... was <=> it was ...

ranning

对，就是这个when的关系，when的出现使得its number were不补出也不会产生歧义

省略的情况补不补出助动词关键还是看会不会有歧义，做到后面你会发现如果主句的谓语有宾语，比较的主语后面就要补出助动词。时态的问题属于可省可不省的状况，但是放心肯定不会给两个一模一样的选项，一个省了，一个没省，这样考你。大部分情况时态不同，助动词是补出了的

下面这道题也是典型的比较中出现从句

Because the Earth's crust is more solid there and thus better able to transmit shock waves, an earthquake of a given magnitude typically devastates an area 100 times greater in the eastern United States than it does in the West.
(A) of a given magnitude typically devastates an area 100 times greater in the eastern United States than it does in the West
(B) of a given magnitude will typically devastate 100 times the area if it occurs in the eastern United States instead of the West
(C) will typically devastate 100 times the area in the eastern United States than one of comparable magnitude occurring in the West
(D) in the eastern United States will typically devastate an area 100 times greater than will a quake of comparable magnitude occurring in the West
(E) that occurs in the eastern United States will typically devastate 100 times more area than if it occurred with comparable magnitude in the West

补充og上两道补出和省略的例子

A study commissioned by the Department of Agriculture showed that if calves exercise and associated with other calves, they will require less medication and gain weight quicker than do those raised in confinement.

A) associated with other calves, they will require less medication and gain weight quicker than do

B) associated with other calves, they require less medication and gain weight quicker than

C) associate with other calves, they required less medication and will gain weight quicker than do

D) associate with other calves, they have required less medication and will gain weight more quickly than do

E) associate with other calves, they require less medication and gain weight more quickly than

这一题og解释说这个比较是两种calves之间的，do扰乱了比较结构，必须去掉，不然是错的。

Inuits of the Bering Sea were in isolation from contact with Europeans longer than Aleuts or Inuits of the North Pacific and northern Alaska

ans: isolated from contact with Europeans longer than were

这里补出were是因为原文有歧义，看不出因纽特人是和谁隔绝了，加上were，逻辑意思清楚

第一道题着重考的是时态。只利用时态就可以解题了

至于do，倒不是说必须去掉，而是这个助动词补错了

lsaurora

第一题用时态解是没有问题，关于do ，og上写的是the verb do ungrammatically interrupts tha comparison and should be eliminated;

这里前面require and gain 两个动词，我感觉补出是会有歧义的。
