Question

Mary often helped her mother ________ out the trash last year.

A．takes

B．took

C．taking

D．take

Answer 1

D

试题分析：句意：去年玛丽经常帮助她的妈妈扔垃圾。help sb to do sth 帮助某人做某事，to 可以省略,同时help还有一个短语是help sb with sth帮助某人某事，故选D
点评：英语中有很多固定的用法，诸如finish,enjoy,mind,practice等词后接动名词的形式，而would you like，ask,tell等词后都接动词不定式的形式，此类固定用法要求学生进行牢记。
