关于定语从句的两道题
The washing machine __last Wednesday works well
A.I bought B.I bought it C.which I buy D.that I bought
我选D的,可是我觉得A也可以哎..请告诉我怎么分析
The doctor __is going to Europe next year.
A.which the manager is talking to
B.who the manager is talking
C.the manager is talking to him
D.the manager is talking to

第一道是答案有问题...AD都是对的...
第二道选D,还原后是the manager is talking to the doctor...doctor在定语从句中充当宾语可省略that、who、whom...
