题目内容

The students_____ until the heavy rain stopped.

A.didn’t go         B.went             C.are going          D.can’t go

 

【答案】

A

【解析】

试题分析:此题考查固定短语not…until表示直到…才,根据语境可知此句的含义是直到大雨停了学生们才走,因the heavy rain stopped用的是过去时,故主句也要用过去时,故选A。

考点:not…until

点评:until可用作介词或连词,意为“到……时候为止”、“到……时候才”或“在……时候以前不”。什么情况下表达什么意思,关键要看(主)句中的谓语动词是终止性动词还是延续性动词。

1. 如果(主)句中的谓语动词是终止性动词,应采用“... not ... until ...”结构,意为“……到……时候才……”。

2. 如果(主)句中的谓语动词是延续性动词,那么谓语动词用肯定式或否定式,它们所表达的意思有所不同。

1) 如果谓语动词为肯定式,则until译为“到……时候为止”。

2) 如果谓语动词为否定式,则until应译为“到……时候才”,即“在……以前不”。

3. 用终止性动词作谓语时, until既可以和not连用,又可以和never, nobody, nothing, few, little, seldom, hardly等含否定意义的词连用。

4. 连词until引导的从句中谓语动词的时态。

1) 主句的谓语动词为一般现在时或一般将来时时, until从句中的谓语动词为现在完成时,用来强调从句谓语动词表示的动作发生在主句谓语动词表示的动作之前。

2) 主句中的谓语动词为一般过去时时,从句中的谓语动词为过去完成时,用来强调从句谓语动词的动作发生在主句谓语动词表示的动作之前。
