四 重点语法
1. ‘It is + adj+ to do sth’: 该句型中it为形式主语,不定式to do sth为真正主语.如:
It is possible to finish it within an hour.
It is right to help others.
It is wrong to look down on poor children.
2. ‘It is + adj + for sb + to do sth’: ‘for sb’ 是指”对某人来说”,通常有’me, you, him, her, us, them”等.它与’It is + adj + of sb + to do sth’ 的区别是: of sb形容词表示的是人的性格道德品质,而for sb仅表示”对某人来讲”,形容词是用来描述某件事情的.
3. ‘It is + adj + that 句子’: 上面两项的真正主语是动词不定式, 而这儿是一个句子,有主语.如：
It is dangerous that you cross the road now.
It is necessary that you train yourself before the walk.
