谢谢阿！

Answer 1

为你解答。
He
does
a
lot
of
exercises
every
day.(他每天做大量的练习题。)
He
exercises
a
lot
every
day.(他每天进行大运动量的锻炼。)
解释:第一句的exercises是可数名词复数，意为练习题。
第二句的exercises是动词，而且为三单形式，意为锻炼。

Answer 2

根据题意，A，C排除，因为arrive是短暂性动词，不能用until，所以只能选B

Answer 3

如果选D，意思是：是，他昨晚8点还没回来，句子意思前后矛盾。
又因为A,C都不可能，所以选B

Answer 4

选择B
