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。

不明白这道题的总体积为什么是(x+2)(y+2)(z+2)而不是(x+1)(y+1)(z+1);厚度不是1吗?谢谢!

提问:

我觉得这题答案应该是A吧?∵105拆分质因数可得105=3*5*7(3个完全不同的质因数)∴x+y+z=15。怎么会是C呢????

提问:

想向May老师提问。这题我知道条件1单独成立,但对条件2没什么思路,只能想到穷举法,当p等于2*5,3*5,3*5,2*3,2*5,3*5时,m等于2*3,2*3,2*5,5,3,2,然后一个个除发现有的余数是1,有的余数大于1,条件2单独不成立。想问老师这个思路对吗?有没有更加简洁的思路?

提问:

第8题的思路是以BC为底,从F向BC做垂线,跟BC交点H,FH为三角形FBC的高。然后三角形BFH跟三角形BDC相似,h:30=BF:BD,但是BF长度未知,望老师解答。
