1、牢记句型结构it is... that/who
2、比如说强调事物东西就用it is thatIt is the very dress that I will wear next date with my boyfriend.其中 the very dress 就是强调的东西，是这件裙子而不是其他的衣服。
3、句型it is... whoIt is my uncle who drove me to the university.着重说明是我叔叔载我到大学的，不是其他人
4、还有一个就是 it is not until...thatIt is not until 11 o'clock I go to bed.直到11点我才上床睡觉。
