题目

he often thinks of ()he can do more for the four modernizations.这里面为什么能够判断他
少的是状语,而i can't understand ()they insist on going by motorbike中是少了定语呢?单看一个句子,怎么知道先行词有没有被省略了呢?定语从句先行词省略了,却关系代词不知道的情况下,那怎么和状语从句区别开来呢?

答案

he often thinks of 【how】he can do more for the four modernizations
he (主语）often（状语（ thinks of （谓语）【how】he can do more for the four modernizations（宾语从句）
i can't understand【why】they insist on going by motorbike
我不明白他们为什么坚持要骑摩托车去.
they insist on going by motorbike 这是个宾语从句.主谓宾齐备,显然从整个主从复合句来看,是缺一个副词why"为什么”,指“原因”
they （主语）insist on （谓语）going by motorbike （宾语）
------两个句子,我没看到哪个和定语从句有任何关系呀?!
