问题描述：
The customers often complained ___they have bought from that shop
that
which
what
where
答
选what.
这里what引导一个宾语从句,代表complain(抱怨)的内容.整句可翻译为:
顾客经常抱怨从那家店买的东西.
答
好像complained后面少了一个about
选what.
they have bought是宾语从句,bought是及物动词,缺少宾语,所以what(连接代词)作宾语.如果用that,则bought后面还需要宾语,另外两个词不合要求.
答
what
答
what = the thing which\that
答
what
先看从句thay have bought from that shop 不是一个完整的句子,所以应该用which,但是complain 少一个介词about(complain about是固定搭配）
所以要选what(what=about which)
