单选题 Professor Johnson will come to give a lecture ______ next month.
【正确答案】 D
【答案解析】[考点] 形近词辨析
[解析] 这四个选项在形式上非常相似,但意义大不相同。some times“数次”,类似用法如:nine times out of ten“十有八九”。sometimes(副词),意为now and then(有时),如:I sometimes have letters from him.(我有时会接到他的信。)some time:some是形容词,修饰time,要分开写,意为a period of time“一些时候”,如:I have"t been there for some time.(我有一阵子不去那儿了。)sometime:与at some time“于某时,在某一时候”(副词)同,如:I saw him sometime in June.(我在6月份见过他。)根据题意应选sometime,即“Johnson教授将在下个月的某一时候来做一个讲座。”
