20、st yesterday. 这和我昨天丢的笔一样。（类似的笔） This is the same pen that I lost yesterday. 这支笔就是我昨天丢的那支。（同一支笔）非限定性定语从句用as和which引导的区别意义上：as 含有“这点正如一样”which 没有。 as引导的非限定性定语从句既可以放在主句之前，也可以放在主句之后，但which或who引导的非限定性定语从句不能放在主句之前。如：He didnt pass the exam, as we had expected.There is lots of air in loose snow, which can ke
