i saw him taking out a paper请问,TAKING 这里是动名词还是现在分词为什么 I saw him go out just now. I saw him go out.为什么不能写I saw him went out I saw him to go out to play改错 I saw him----off his clothes and ----into the river to save the boya take,jump b taking jumping c taking jump d take jumping I saw him _______(put) on his coat and ______(go) out just now i saw him (go) out of the room.三单后不是跟goes吗? I saw him go out of the room.(第二个动词go为什么不用过去式..谢) I saw him come out of the cinema.come 为什么是原型? I saw him _____(进入)the Building A yesterday afternoon but he didn’t come out. i saw him get out of room just now 请问为什么get不是wet或getting? I saw him ( )out of dolls.A go B had go C hsa go D goes we saw him out.是做宾补吗?为什么? I saw him go out just now.同义句转换He ____ ______ _____go out just now. He can't be home now, for I saw him() in the gym just now.giving out/working out为什么不是giving out this is the man_____last nightAwhom I saw him Bwho I saw Cwhich I saw Dwho I saw him -IS jack in the library?-Mabaybe.I saw him _____ out with same book just now.A:gongB:go -Is Jack in the library -Maybe.I saw him( )out with some books just now.为什么不是“went而是go
