反意疑问句You must have worked there a year ago, didn’t you? 对吗???

如题所述

你好,同学

这句话是对的,即

You must have worked there a year ago, didn’t you?

翻译:一年前你一定在那儿工作,不是吗?

解析:反意疑问句中含有Must的情况主要有以下几种:

1)作为情态动词表“必须”,这时反意疑问句直接用mustn'/needn't

2)当must表示推测时又分以下几种情况:

a:对现在事实的推测,反意疑问句与must后面的动词呼应,如:

You must be joking,aren't you ?

b:对过去事实的推测,表示动作的时候用did 当助动词,表示状态时用was,如:

Mr Green must have been punished for his being rude at the meeting,didn‘t he ?

(格林先生一定因为昨天在会上鲁莽的行为被处罚了,是吗?) 被处罚表示一个动作

She must have been a policeman ,wasn't she ?

(她过去一定是个警察,是吗?) 是警察表示一种状态

对现在情况的推测,问句部分用主动词(do,be)一般现在时的适当形式。若是现在进行时,问句部分用现在进行时的适当形式表示。若是there be结构,问句用isn't/aren't there。如:

1)He must be there,isn't he?

2)He must have a big family,doesn't he?

3)He must be waiting outside,isn't he?

4)There must be some students in the room,aren't there?

对已发生的过去情况的推测,若陈述句谓语部分有“must have done”,而且有表示过去的时间状语,问句部分用didn't;若没有表示过去的时间状语,问句部分用haven't或hasn't。如:

1)They must have gone there last night,didn't they?

2)They must have arrived by now,haven't they?(根据by now来判断)

3)They must have been to the Great Wall,haven't they?

本题正符合:对已发生的过去情况的推测,若陈述句谓语部分有“must have done”,而且有表示过去的时间状语,问句部分用didn't,因为句中有表示过去的时间状语a year ago。

希望能帮到你,祝更上一层楼O(∩_∩)O

你好。很高兴为你解答。这是对的,must have worked 表推测而完成时,而a year ago表示一般过去时,所以用didn't you是正确的。欢迎追问,祝你学习进步,天天向上。

不对哦,ago 一般不与完成时连用,一般于一般过去时连用,改为you worked there a year ago,didn't you?
