99. These computers are different from ________.
A. that we expected B. what we expected

为什么选B，不选C？
These computers are different from ________.99. These computers are different from ________. A. that we expected B. what we expectedC. which we have expected D. what we expect为什么选B，不选C？
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
我们以前所期待的，而不是现在所期待的，应该根据句意。
which 通常需要指定范围。这个选择题看不出候选范围。
C选项使用了现在完成时，这个应该是想感慨与意料中的不同，应该过去时
