【題目】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：在任何不安全的情況下，僅僅摁一下這個(gè)按鈕，一個(gè)訓(xùn)練有素的特工就會(huì)使你得到你需要的幫助。and是連詞，連接并列結(jié)構(gòu)，and后面是一個(gè)句子，那么，前面也應(yīng)是句子，選項(xiàng)中只有動(dòng)詞原形可以構(gòu)成祈使句，其余的都是非謂語(yǔ)動(dòng)詞，無(wú)法構(gòu)成句子。故A選項(xiàng)正確。
