He wa seen to come upstairs 中的 to come upstairs 为什么不能看成目的状语呢?不是有to吗?这个我不理解 he was seen to come into the room last night 为什么用seen为了做老班布置的题.. He was seen to come in中to come in是什么成分?宾补可不可以跟在表语后面? he was seen--into the room .这个空 因该是 came 还是 come 还是 to come 还是 comes摆脱了、 I was___him last Wednesday but he did't come选项A.about to see B.to see C.about to have seen D.to have seen they were seen to come out of the housewere seen WA TA XI WA TO TE MO U LE XI DE Whether he will come is still u------- to us.Anyway ,we will wait for him.
