  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.
 
  以上就是为大家整理的高中英语语法大全之"IT"句型,希望同学们阅读后会对自己有所帮助,祝大家阅读愉快。
