These computers are different from ________.
99. These computers are different from ________.
A. that we expected B. what we expected
C. which we have expected D. what we expect
为什么选B,不选C?
These computers are different from ________.
这里有介词from,是介词宾语从句 所以是B
而C 虽然也可以理解成宾语从句,但是,which 不对,时态倒是也可以讲得通
就是what 和which 的区别了
有范围的情况下,用which ,没有范围的情况下,用what
这里是没有范围,没有这几个电脑之类具体的范围,因此用what
