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 confinedment.

A. the same

B. ...

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

The best answer is E. I do not understand why not they will require ... and will gain, since it is conditional clause: if ..., they will.  Who will help me out? Thank you.

if calves exercise and associate with other calves, they require less medication and gain weight more quickly than those raised in confinedment

如果表示客观存在的规律，主从句都用一般现在时。

1, 因为选项里没有既满足will require...and will gain..，又满足associate with的选项

2,同意2楼tianwan的意见~~

如果在E中补出do可不可以呢？

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

什么时候可以省助动词，什么时候不可以省呢？我不太清楚，请指点

"do" can be added, but ets may say it's wordy because the "do" doesn't help clarify anything. on the other hand, for the sentence "calves gain more fat than do those raised in confinement," do is a must because, without it, confusion may occur: comparing calves (subject) or fat (object) with calves raised in confinement.

多多讨论...

gg，转一圈回来重新看题，找了LZM的书说，在谓语一致，比较主语时，than后面的助动词要补出。这题里面是主语一致，比较的是谓语动作，所以我想do就不需要的。不知gg觉得如何？

scots

晕。。我的语法好菜。。

我有一个想法，可不可以是因为than前面需要比较的动作有两个，一个是require，另一个是gain，如果加了do，到底do是替代require呢，还是替代gain呢。。这不就导致了指代混乱吗？？？所以不加do了吧？？

babypace and scots MM: the key is to ensure the clarity of comparing targets. personally, i was mis-directed by LZM's book on this issue. his "axioms" only touched the surface. but ETS' fundamental is about clarity without unnecessary verbiage. there are many kinds of comparisons. i tried to make an axiom for each kind of comparisons, but it was too troublesome! JerryGuan gg summarized a bunch of SC's involving comparison. 有时间, 细细体会ETS的原则... http://forum.chasedream.com/dispbbs.asp?boardid=23&id=43981
