提问:

老师您好,我听了您的基础课解释的为什么分子只能有一个C[1,60],但是还是不太理解。在第一个班(e.g. senior)sibling里选一个是C[1,60],另一个班就是C[1,1] 而不是C[1,60]呢? 我不懂的点在于 题目说是两次选取都是random的,也就是在图中大写A里选出姐姐,不代表一定会在小写a 里选中她对应的妹妹呀? 这里我比较糊,能麻烦老师您解释一下吗?谢谢!

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。
