我遇见的数学机经很少,就5道左右。
语法
有一道gwd原题,我先发点我记得的,晚上再仔细找下,are yielding an account of history that
is as invalid as its details of
is so invalid as its details of
is so invalid as their details of
are as invalid as their detalis of
are.............
顺序不一定对,选第一个
晚上我找下原题
我遇到的第一道语法就是考prohibiting的用法
from是在划线部分后但紧挨着划线部分的,所以大家千万别选选项里带from的
正确选项应该是prohibiting the impotation of Keru
还有道很明显的
like driving for ...,the drive for...
选项里只有一个是
like drive for ...其余都是like driving 活着just as 开头明显不对 |
