The only thing ______ I knew is _____ my brother said to me the other day.The only thing ______ I knew is _____ my brother said to me the other day.A.which… what B.that… what C.what… that D.that… which为什么不选C?
答
B
I knew 是定语从句修饰The only thing,当先行词被the only 修饰时注意只能用that,而不能用which 指事物
what 就更不能了,因为what不能引导定语从句,修饰名词,代词
第二空用what 引导表语从句,what 在从句中作said 的宾语,不可以用that 引导,因为that 引导从句时,没意义,不能在从句中作宾语
可见,不能选Cwhat 可以引导名词性从句， 做主语， 宾语， 表语，同位语
