这里主要总结一下有have等动词的情况,than后面的代词是否可以省略的规律~其实我也说不出是在比较什么成分,但是就是发现了一个小规律,目前没发现例外~大家做题总结的时候可以参考一下是否真的是这样~
总的来说:1.比较have等动词前面的名词时,后面不能加that;2.比较have等动词后面的名词时,that,those等代词不能省略
上例子:
1. than后面不能用代词的情况:
OG18-775
According to recent studies comparing the nutritional value of meat from wild animals and meat from domesticated animals, wild animals have less total fat than do livestock fed on grain and more of a kind of fat they think is good for cardiac health.
- A wild animals have less total fat than do livestock fed on grain and more of a kind of fat they think is
- B wild animals have less total fat than livestock fed on grain and more of a kind of fat thought to be
- C wild animals have less total fat than that of livestock fed on grain and have more fat of a kind thought to be
- D total fat of wild animals is less than livestock fed on grain and they have more fat of a kind thought to be
- E total fat is less in wild animals than that of livestock fed on grain and more of their fat is of a kind they think is
与此题相似的是:
OG18-784
Most of the country`s biggest daily newspapers had lower circulation in the six months from October 1995 through March 1996 than a similar period a year earlier.
- A a similar period
- B a similar period’s
- C in a similar period
- D that in a similar period
- E that of a similar period
通过这两题发现,比较的对象都是have前面的名词,即wild animals(的脂肪),报纸(的流通量),所以后面不用代词,并且分别省略了than lovestock (do)和than (newspapers had)
2. 再看另一种情况,than后面必须要补出代词的:

Today’s technologyallows manufacturers to make small cars more fuel-efficient now than at anytime 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 intheir C. small cars that are more fuel-efficient than those at any other time in D. more fuel-efficientsmall cars than those at any other time in their
E. more fuel-efficient small cars now than at any time in
这两题比较对象都是动词后面的名词,前者是大米有的蛋白质(的质量),后者是制造商制造的车(的燃耗效率)所以必须要有that/those指代
简单粗暴的判断方法...适合和我一样不太懂各种成分什么状语比较之类的同学~仅供参考~找到反例的话请一定要贴出来!
