That fellow wants ___ on the watch carefully .Don’t let him

That fellow wants ___ on the watch carefully .Don't let him escape.
A.to keep B.to be keeping C.keeping D.being kept
选BCD答案的人都有,但还是拿不准是哪个正确?

C.楼上几位的回答都是答非所问,不知所以.这是个被动句,意思是仔细盯紧点那家伙,别让他逃脱了.keep sb on the watch意思是监视某人,放在主动句中正确语序是Somebody keep that fellow on the watch ,而这里是that fellow作主语,明显是被动句.在被动句中有些单词能后跟主动形式(ing)表示被动,常用的是need,want,merit,deserve.这里就是用want的ing形式表示被动, sb(sth) want doing意思是某人(物)需要被怎么样.比如说我的表需要被修理,就可以说My watch needs/wants/deserves/merits repairing.另外,need,want,merit,deserve后面也可以直接跟to be done表示被动,比如说我的表需要被修理,也可以说
My watch needs/wants/deserves/merits to be repaired.
楼主问的这道题如果是填空题的话,两个答案,一个是keeping,另外一个是to be kept.根据所提供的选项,选择c

这个问题我还想问问老师呢
