一:been是什么意思?
been是be动词的过去分词形式,表示“已经”,“曾经”等含义。它可以用来表示某件事情发生过,也可以用来强调某人或物的状态或属性。
been的音标为/biːn/。
1. 表示过去发生过的事情:
I have been to Paris twice. (我曾经两次去过巴黎。)
He has been to Japan before. (他以前去过日本。)
2. 表示某人或物的状态或属性:
She has been sick for a week. (她已经生病一周了。)
The book has been translated into many languages. (这本书已被翻译成多种语言。)
3. 与完成时态连用,表示动作持续到目前:
I have been studying English for 5 years. (我已经学习英语5年了。)
They have been living in New York since 2010. (他们自2010年以来一直住在纽约。)
4. 与情态动词连用,表示推测:
He must have been tired after the long trip. (长途旅行后他一定很累了。)
She might have been busy with work last night. (昨晚她可能忙于工作。)
5. 在被动语态中,表示被动的状态或行为:

5. They must have been very happy when they heard the news. (当他们听到这个消息时一定很开心。)
1. gone:也是be动词的过去分词形式,表示“离开”或“消失”。与been不同的是,gone更多地强调动作或状态的变化。
例句:She has gone to London for a business trip.
2. existed:表示存在或生存,与been相似,但更加正式。
例句:Dinosaurs existed millions of years ago.
3. lived:表示居住或生活在某地,与been的用法类似。
例句:They have lived in this town all their lives.
been作为be动词的过去分词形式,在英语中使用频率较高,可以表示过去发生过的事情,强调某人或物的状态或属性,也可以与完成时态连用表示动作持续到目前。同时,它也可以与情态动词连用表示推测,在被动语态中表示被动的状态或行为。除了been之外,还有一些同义词可以替换使用,gone、existed和lived等。在使用时需要根据具体语境来选择合适的词汇。
