[2] 1}只能用that不能用which的情况 1)当先行词既有人又有物时 2)当先行词被序数词或最高级修饰时 3)当先行词被very some any only等词修饰时 4)当先行词本身就是不定代词时『ps。不定代词就是 anything everything all nothing之类的词』 5)定语从句中缺表语时 6)在疑问词who和which后出现的定语从句
[6]as与which 1)引导非限制性定语从句,且放句首时只能用as不用 which『我们很熟悉的As we know ,。。。 As you can ,。。。』 2)前面有the same/such/so时只能用as 『这点非常隐 蔽,题中总是没看到反正我是这样的』 3〕当翻译成 “ 正如???那样”时,只能用as
[1]一般现在时。。。(do,does,is,am, are)→→被动→→do/does/is/am/are+done 用于三种情况 1)表习惯 eg.He is blamed by his mother every day. 2)客观真理 eg.The sun rises in the earth. 3)名言警句 eg.He said failure is the mothe of success.
