一道选择题
Look,they seemed ___. A.to play with computers B.to play computers C.to be playing with computers D.to be playing computers
sem to be doing sth 先D
黑羽信 ：play with 有玩弄的意思，play 就不是这个意思。
我怎么觉得选C 呢 首先 seem的三个结构： seem to do seem to have done seem to be doing 因为是在进行的 所以用进行时 然后 play做不及物动词（与with连用）解释＂玩＂ play做及物动词解释＂打（牌、球）＂ 于是我一直在想是play computers 还是playing with computers 去查过： play with有两种讲法 play with the computers和play the computer games是玩电脑 how to play the computer 是怎么操作电脑 所以我觉得选C.... 唉．．．
选D
选d
选C D多了个WITH
