问题 Professor Jones will come to give a lecture on Canadian history______ next month.

选项 A、some times
B、sometimes
C、some time
D、sometime

答案D

解析 这四个选项在形式上非常相似,但意义大不相同。some times“一些次”,类似用法:nine times out of ten“十有八九”;sometimes(副词)=now and then“有时”,如:I sometimes have letters from him.“我有时会接到他的信。”some time中的some是形容词,修饰time,要分开写,意为a period of time“一段时间(或一个时期)”,如:I haven’t been there for some time. “我有一阵子不去那儿了。”sometime=atsome time“于某时,在某一时刻”(副词),如:I saw him sometime in June.“我在六月里见过他。”根据题意应选sometime,即“约翰逊教授将在下个月的某一时候来开一个讲座”。
