It is ....that ..

1.it is +n/adj+that it一般是做纳漏睁形式主语，that后面的才是真正的主语 eg：it is right that the temple was rescued。拯救这座寺庙是做的对的。 it is no wonder that she is so ill。她病得这么厉害是不足为怪的。 2.it is +过去分词+that 这种用法通常主语不明确。 比较常见的是it is said that 据说，it is seen that人们看到 it is known that总所周知 it is told that 有人曾经说 eg：it is decided that i will meet them at airport。根据决定我去搜孙机场接他们。 3。强调句型。 其实在做题的时候，出现这个结构你首先要判断是不是强调句，如果不是，你再从其他句型分析，这样才洞岁能提高正确率。
