请问这道选择题考的是什么知识
Heusedto_____histeachingwhenhewasyoung.A.devotetoB.devotingtoC.bedevotedtoD.beingdevo...
He used to _____his teaching when he was young.
A.devote to B.devoting to C.be devoted to D.being devoted to 展开
A.devote to B.devoting to C.be devoted to D.being devoted to 展开
展开全部
两个知识点:
1.used to do表示"过去常常做某事",暗含现在已停止.
2.devote oneself/sth to"热衷于,投身于"to 是介词.devote 为及物动词.此处用了被动语态的形式.
原句应该是这样子的:
He used to devote himself to his teaching when he was young
故选 C
