一道白勇语法，好象在其他的地方也见过？

21. It is an oversimplified view of cattle raising to say that all one has to do with cattle is leave them alone while they feed themselves, corral them, and to drive them to market when the time is ripe.
(A) all one has to do with cattle is leave them alone while they feed themselves, corral them, and to
(B) all one has to do with cattle is to leave them alone to feed themselves, to corral them, and
(C) all one has to do with cattle is leave them alone while they feed themselves and then corral them and
(D) the only thing that has to be done with cattle is leave them alone while they feed themselves, corral them, and

 

答案是C呢，可是is  和leave 不都是动词吗，可以一起用吗。

还有all one和 the only thing 有什么区别啊？

 呵呵...

the only thing & all one has to do...这两者的区别你再好好考虑下是可以看出的--前者指"只要做的一件事",而后者是说"一个人所有要做的事"...

呵呵,我也有点晕了,就看E吧:

the only thing that has to be done with cattle is leave them alone while they feed themselves, corral them, and

 the only thing和后面的几个动作没矛盾吗?

the only thing明明就是说一件事,但后面又来了好几件事...

哎...死...我不仅英语烂,语文也烂...

真是...算是帮你顶起来吧,等NN给你解释吧~

我想问问是不是有这种结构  all  one  has to do with  sth  is  do 呢？

遥远的绿洲

本题结构是一个很常见的省略结构

...have to do is (to) do...   to经常被省略

记住这个语法点就可以了

根据并列原则和主动优先原则选C

选项E是什么? 我看不到呢

carp

根据要补都补的原则，如果认为 leave ，corral
                , drive 并列的话只有D和E符合。

不过根据内容，corral 和drive是并列关系，而和leave有先后关系，所以选C 

lanyuqi

为什么不用are 而用is 呢。all 做主语不是谓语要用复数吗

all （that) one  has to do with  sth  is (to) do
