这个地方，答案是用现在进行时，怎么理解？

Answer 1

22：A的意思是“直到”，放入原文意思就是：我们不知道交通是拥堵的，直到你告诉了我们。
B的意思是“除非”，这个放入句子中意思就不通顺了。A/B/C/D在语法是没有问题，所以就是词义的辨析。
23：A选项的Since一般用在现在完成时中，原句不是，所以不符合题意。这句话中有个will be，是将来时态的标志，整个句子表示的是一种将来的情况，同样从词义角度考虑，B/D都是不准确的。
32：答案选D
A + be + 倍数 + as + 计量形容词原级 + as + B
A + be + 倍数 + 计量形容词比较级 + than + B
A + be + 倍数 + the + 计量名词 + of + B
The + 计量名词 + of + A + be + 倍数 + that + of + B
33：题意是你总是在看电视。为何不做些活动？之所以用现在进行时，是因为“总是看电视”这一行为对现在造成了影响，并一直在延续。这不正好是现在进行时的定义嘛。
