32.Once ______,the clock will last a month and keep good time.
A.start B.started C.to start D.starting

答案：B
此题牵涉到高中英语一个比较重要的语法：状语从句的省略.
1.该语法规定：如果状语从句的主语是it,或和主句主语一样,且从句的谓语动词含有be动词的话,则可以同时把从句的主语和be动词去掉.
这个语法一般运用于时间、条件和让步状语从句.
2.此题即：Once started = Once (the clock is) started 这钟表一旦被启动的话,.
再如：If (I am) invited,I'll go to the party.
