强调句
1．It is/was +被强调部分+that/who…
对于这个结构，需要注意以下几点：
①强调句型中的系动词除is和was之外，没有其他形式的变化;
②被强调部分如果是人，可以用who, 也可以用that,其他情况用that（常识性知识，一般不能作为考点）。
③在not…until句型里，如果强调由until所引导的时间状语时，not须跟在until之前，即构成It is not until…that结构。
It is because she is too inexperienced that she does not know how to deal with the serious situation.
她不知道如何应对这种严重情况是因为她太缺乏经验了。
It is because the water had risen that they could not cross the river.
正是因为水涨了，他们没有渡过河去。
注：强调的如果是原因状语从句，只能由because引导，不能由since, as或why引导。
