这几道题我都选错了 不知道是什么原因帮忙解释下吧
上面说的挺对，不过18题的it应是形式宾语
C,it,C,A
not应该放在主句上
It +be +形容词(+ for sb) +to do sth;
一般说来，在It [This] is the first/second time＋that-结构中，that-从句通常用现在完成时;
be 后面加形容词，soon,shortly是副词，而且后面是一个句子，要一个连词
17.C
think否定用法 not应该在主句上.
I didn't think that he might take the exam.这样就对了.
AB里面的it都是指代take the exam这件事.
18.it
it在这里做形式主语,指代master a foreign language这件事
其实填写it is也是对的,但外国人不常这么用.
19.C
固定句式This is+次数+现在完成时
This was...+过去完成时
20.A
不久我们就会再次见面的.
这个句子应该这样看It won't be long / before we meet again.
不要将long before看成一个词组,因为long before是很久以前的意思,看成词组就会做错.
before long后面加的不是从句,所以不选.
还有两个应该不需要解释.
