B
如是A的话,应该是用现在完成时.为什么呀？我觉得两个都可以！能解释清楚些吗？谢谢啦啊Did youknow ( ) ?AIf he bought? a carnerayesterday? BWherehelives?He said heknew(). AWherethe manager lived?BWhere themanager livedin?能帮我再解释一这两道题吗？AWould（Could ) you ...?这句型不是过去时，而是语气更婉转，所以不能用过去完成时。Did you know ( if he bought a camera yesterday )? Did是过去时， 所以宾语从句应该与did一致。He said he knew ( A ).B多了介词in ,因为 where 是副词。
