B. to talk, quietly
C. to talk, quiet
D. talking, quiet
答案:
A. talking, quietly
B. to talk, quietly
C. to talk, quiet
(答案→)D. talking, quiet
解析:stop doing sth.是停止做某事,指停止做原来的事。如: Hearing the doorbell,she stopped washing the dishes. 听见门铃声,她停止洗碗了。 stop to do是停下(手头的事情)去做另外一件事。如:Hearing the dollbell, she stopped to open the door. 听见门铃声,她停下手中的活去开门。本题是说老师来了,当然是指应停止交谈,用stop doing;keep后应接形容词作表语,keep quiet“保持肃静”。故选D。
