1.—Do you think you could work for 24 hours without___a rest.
---I've never tried that___.
A.have;before B.take;ago C.having;ago D.taking;before
2.I didn't know___learn a foreign language well___I was child.
A.how could I;when B.how to;after C.how I could;when D.how to;until
第一题选D
without 后面加doing,take a rest固定搭配,表示休息
before表示"以前",ago的话前面一定要加一个具体的时间,比如2 days ago,它不能单独使用.
第二题选C
第一个空B和C都可以选表示"如何去",但是后面一个空根据意思"在我孩子的时候"只能选C.
d without 后加动名词形式所以have &take错了
I've never tried that before,这里只能用before 译为 我 从来 没有尝试过
D
WITHOUT后加名词，所以CD，完成时用BEFORE
C，间接句，疑问顺用陈述句语序，根据句意是当我是孩子时
