"That day I saw some parents ________ at the back of classroom, ________ to the teacher.
A. sitting; listened
B. sat; listened
C. sltting; listening
D. sat; listening"

Answer 1

答案C
此题题眼为saw some parents，see为感官动词，感官动词后跟动词有两种形式，即see sb. do sth.（看见全过程）和see sb. doing sth.（看见某人正在干某事），所以答案应在A和C中选。sitting表示正在进行，是现在分词，后面是看见一些家长正坐在教室后面听老师讲，表示伴随的动作，也应用现在分词形式。
