【题目】In any unsafe situation, simply _________ the button and a highly-trained agent will get you the help you need.

A. press B. to press C. pressing D. pressed

【答案】A

【解析】考查祈使句。句意:在任何不安全的情况下,仅仅摁一下这个按钮,一个训练有素的特工就会使你得到你需要的帮助。and是连词,连接并列结构,and后面是一个句子,那么,前面也应是句子选项中只有动词原形可以构成祈使句,其余的都是非谓语动词,无法构成句子。故A选项正确。
