— Things in your room are all over the floor. Be sure to__________before the guests__________.
— No problem.

A．tidy it up; arrive

B．tidy it up; reach

C．tidy up it; arrive

D．tidy up it; reach

答案

A

解析

试题分析：句意：—你房间的东西都散落在地板上。在客人来到之前，应确保收拾整齐。— 没问题。tidy up整理，后面跟名词时，在up之前，之后均可，跟代词作宾语时，只能放在up之前，再有，arrive是不及物动词而reach是及物动词，故选A。
考点: 考查动词短语和动词词义辨析的用法。
