As they were walking around, they noticed a man _______ against a tree.
A.sitB.to sitC.sittingD.sat
题型:单选题难度:中档来源:不详

答案

C

试题分析:句意:当四下走动的时候,他们注意到一个人在倚着树坐着。此处是非谓语短语做补语,感官动词后不能跟to do做补语,故排除BD选项; Notice sb do sth意思是“看到某人做某事了”表示看到动作的整个过程,而notice sb doing sth 意思是“看到某人在做某事”,表示正在进行的动作,根据句意可知选C。类似动词还有see 、hear、observe等。
