It is no use him to give up smoking He won’t listen!A. to persuadeB. trying to persuade

问题补充：

It is no use him to give up smoking． He won’t listen!

A. to persuade

B. trying to persuade

C. persuading

D. try to persuade

答案：

A. to persuade

(答案→)B. trying to persuade

C. persuading

D. try to persuade

解析：本题考查非谓语动词。It’s no use doing sth.为固定用法，表示“做某事没用/只是白费力气”，由此可以排除A和D；persuade sb. to do sth.意为“说服某人做某事”，强调劝说成功。如果劝说不一定成功，可用词组try to persuade sb. to do sth. 根据句意“劝说他戒烟是没用的”可知不一定成功，故答案为B项。
