Been是英语中过去分词的形式,通常与助动词have或has一起使用,构成现在完成时态。它表示动作发生在过去,但对现在有影响或结果。例如:I have been to Paris.(我去过巴黎。)
现在完成时态由助动词have/has和过去分词构成。其中,have/has用于第一人称单数和复数,has用于第二、三人称单数和复数。例如:
1. I have been to the library.
2. You have been to the library.
3. He/She/It has been to the library.
4. We have been to the library.
5. They have been to the library.
1. 表示动作发生在过去,对现在有影响或结果。例如:I have been to the doctor.(我去看过医生。)
2. 表示动作从过去开始,一直持续到现在,可能还会继续下去。例如:I have been studying English for five years.(我学英语已经五年了。)
3. 表示过去发生的动作对现在有影响。例如:I have been waiting for you for a long time.(我等你等了好久。)
1. Been表示已经完成的动作,而go表示动作正在进行或即将发生。
2. Been用于现在完成时态,而go用于一般现在时态或现在进行时态。
3. Been与助动词have/has一起使用,而go单独使用。
现在完成时的否定形式是在助动词have/has后加上not,然后跟上主语和过去分词。例如:
1. I have not been to the library.
2. You have not been to the library.
3. He/She/It has not been to the library.
4. We have not been to the library.
5. They have not been to the library.
现在完成时的疑问形式是将助动词have/has放在主语之前,然后跟上主语和过去分词。例如:
1. Have you been to the library?
2. Have you been to the doctor?
3. Has he/She/It been to the library?
4. Have we been to the library?
5. Have they been to the library?
1. Been不能单独使用,必须与助动词have/has一起构成现在完成时态。
2. Been不能与一般过去时态混淆,一般过去时态的构成是主语+动词过去式。
3. 在口语中,有时会将have been简化为have,但书面语中应使用完整的结构。
通过以上七个的介绍,相信大家对been这个词及其用法有了更深入的了解。在日常生活中,正确运用been可以使我们的英语表达更加准确、地道。
