Unit 3 A healthy life Ⅰ.单项填空 1．It is better to ask someone for advice rather than______something. A．risk doingB．to risk doing C．risk to do D．to risk to do 解析 rather than连接前后两个不定式；risk doing“冒险做某事”。句意：最好向别人征求建议而不要冒险做某事。 答案 B 2．—______Larry is in such a hurry? —I don’t know.He might have been running to catch the bus. A．Why do you think B．Do you think why C．Why you think D．Why not think 解析 do you think是插入语，特殊疑问句中含有do you think时，后面部分用陈述语序。 答案 A 3．______ be sent to help her out? A．Who do you suggest B．Who do you suggest that should C．Do you suggest who should D．Do you suggest whom should 解析 考查双重疑问句。do you suggest与特殊疑问词连用时，应放在特殊疑问词之后，又因为suggest后应用(should)＋动词原形，should可以省略，因此A项正确。 答案 A 4．Accustomed to ______ the steep mountain，he had no difficulty reaching the top. |
