提问:

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 (E) the only thing that has to be done with cattle is to leave them alone while they feed themselves, to corral them, and 答案是C,看到原文all one的时候很困惑,不知道指什么,再看到后面的they feed themselves直接就把A排除了,感觉指代有问题,然后竖着扫了一下,发现ACDE都是这种表达,而且B乍一看太平行了,尽管句末少了一个to,当时的想法是 就算有to也不敢选,因为不确定to leave them alone to feed themselves是否改变了句意,所以就不知道该选什么了。麻烦老师讲解。

提问:

7.15/寂静:STUVW, 5个人, V和W中间必须隔一个人,求问共有几种组合? 我的想法是这样的A(3,3)*A(2,2)*C(3,1)=36种;思路如下:先把V+C(3,1)+W看成一个整体;可得:A(2,2)*C(3,1)种排法;然后5个人可分成三类,于是A(3,3)。不知道我的想法对不对,请老师解答。感激不尽!
