【題目】Emergency line operators must always ________ calm and make sure that they get all the information they need to send help.

A. grow B. appear

C. become D. stay

【答案】D

【解析】句意：急診熱線的接線員們必須一直保持冷靜，并確保得到他們所需的所有信息以便派出救助。A項(xiàng)grow和C項(xiàng)become都表示“變化”，與always意義不符合；appear作系動詞，表示“好像，似乎”之意，不符合題意。系動詞stay意為“保持”，符合題意。
