那么,最后一次你把它(书包)放在哪里了呢?
本句中last为副词,意思是“上次;最近的一次;最后一次”。
last除用于句末外,还常置于句子中间。例如:
When I last saw her, she was working in Shanghai.我上次见她时,她在上海工作。
When did you see him last?你最近见到他是什么时候?
"Last" 是一个多义词,可以用作副词、形容词、动词等,在不同的上下文中可以表示不同的含义:
· 表示时间上的最后一次或最后一段时间:
- We saw each other last week.(我们上周见过面。)
- I hope this is the last time we have to deal with this problem.(希望这是我们最后一次处理这个问题。)
· 表示空间上的最后一个或最后一段:
- My house is the last one on the street.(我的房子是街上最后一个。)
- The last page of the book is missing.(这本书的最后一页不见了。)
· 表示最近的、前一个的或刚过去的:
- I saw him last night at the party.(昨晚在派对上我见过他。)
- During the last few months, I've been studying for my exams.(在过去的几个月里,我一直在为考试而学习。)
· 表示最终的或最后的:
- This is your last chance to change your mind.(这是你最后一次改变主意的机会。)
- The last step in the process is to submit the form.(在这个过程中的最后一步是提交表格。)
· 作动词,表示“持续(多长时间)”:
- The movie starts at 7:30, and it lasts for two hours.(电影从7:30开始,持续两个小时。)
【写作用语】
· "Last but not least" 意为“最后但同样重要”
例如:
I want to thank all of our sponsors, and last but not least, our dedicated volunteers.(我要感谢所有的赞助商,最后但同样重要的是,我们敬业的志愿者。)
· "The last straw" 意为“压垮骆驼的最后一根稻草”
例如:
His constant complaints were the last straw for me, and I decided to end the relationship.(他不断的抱怨对我来说是压垮骆驼的最后一根稻草,我决定结束这段关系。)
· I think somebody must have picked it up.
我想一定有人捡到它了。
此句情态动词must表示推测,意为“一定”。
英语中当情态动词后接have done时,表达对过去的事情进行推测,故must have done something表示“过去一定做过了”这样的意思。例如:
He's playing outside. He must have finished his homework,他在外边玩,一定已经把作业做完了。
"Must have done" 通常用来表达对某个过去事件的推断或肯定。
· 表示对过去事件的肯定推测:
- She must have arrived home by now.(她现在肯定已经到家了。)
- They must have finished their project because they're celebrating.(他们肯定完成了他们的项目,因为他们正在庆祝。)
· 表示对过去事件的强烈推断或确信:
- He's been studying all night. He must have exhausted himself.(他整晚都在学习。他
