It is .that ..会出现在几种情形里?比如：强调句.或者其他什么从句（选项中常常作为迷惑强调句的）?ps ：强

1.it is +n/adj+that it一般是做形式主语,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,这样才能提高正确率.
