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 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、 He was seen to cross the street. he was seen to hang out.为什么要to 关于主语补足语① He was seen to come upstairs.② The professor was seen making an experiment in the chemistry lab.请问一下为什么一个后面有TO一个没有?这有没有涉及什么语法呢? He was seen to have entered the room.啥意识 He was nowhere to be seen.为什么要用不定式 I was __him last Wednesday but he didn't come A.I was __him last Wednesday but he didn't comeA.about to seeB.to seeC.about to have seenD.to have seen为什么 He was seen to go into the room 这里为什么SEEN后加TO (seen)to entered the room ,he was asked to the policeman.为什么不是having been seen? he was seen to drink.这个句子对吗? he was seen drinking.呢?he was seen drinking in / at a restaurant.应该用哪一个冠词呢?谢谢大家 They was seen to come into the room by her还是Thry was seen to come by her into the room对?哪个正确 He was seen ( ) into the room last nightA.to come B come C coming D came D为什么是D啊 不应该用ing或原型吗 为什么用into啊老师说的是A He didn't come to school because he was ill对because he was ill提问 he ____ by his sister at that moment.A.happened to see B.was happened to see C.was happened to be seen D.happened to be seen He — by his sister at that moment.A. happened to see B. was happeded to see C. was happened to be seen D. happened to be seen Peter___(come)to school when he was seven
