各科成绩的提高是同学们提高总体学习成绩的重要途径，大家一定要在平时的练习中不断积累，小编为大家整理了高中英语语法之"IT"句型，希望同学们牢牢掌握，不断取得进步!
1.It's time(for sb.)to do sth./It's time for sth.译为“是(某人)该干……的时间了”、“到……的时候了”。如：
It's time for supper /to have supper.
2.It takes(sb.)some time to do sth.译为“(某人)花……时间做某事”。如：
It took me a week to finish reading the book.
3.It is one's turn to do sth.表示“轮到某人做某事”。如：
It's your turn to be on duty tomorrow.
4.It is /has been +时间段+since +一般过去时。译为“自从……以来已过了……(时间)”。此结构可以与另一种句型进行同义句转换。如：
It has been two weeks since we met last.=Two weeks has passed since we met last.
5.It seems /seemed +that从句。译为“看起来好像……”，此结构可以转换成“seem +不定式”形式。如：
It seems that he is ill.=He seems to be ill.
6.It's+adj.+of/forsb.+不定式。对于这个句型究竟用of还是用for，上面许振铎老师的文章中已有论述。这里再强调一下：如果形容词是描述不定式行为者的性格、品质的，如：kind，good，nice，clever等用of;如果仅仅是描述事物的形容词，如：difficult，easy，hard， important，dangerous等则用for。如：
It was very kind of you to visit me when I was ill.
It's important for him to learn English well.
7.It's+表语 +to do sth.。如：
It's a good idea to go out for a walk.=To go out for a walk is a good idea.
8.It's+adj.+ that从句。如：
It's true that he may fall behind the other students.
