【题目】_________ , please start the work tomorrow.
A. If you are convenient
B. If it is convenient for you
C. If it is convenient of you
D. If you have convenience
在线课程【答案】B
【解析】句意：你如果方便的话，就请明天开始工作把。此题考查convenient的用法，表达“如果你方便”时，句子主语不能够说成if you are convenient…，而应该用it做形式主语，即：if it is convenient for you to …。故选B。
