have been只表被动吗

Question

如题所述

Answer 1

have been不仅仅只表被动。

have been共有三种用法。
1.现在完成时
I've been a teacher before . 以前我曾经是一位老师。

How long have you been a dirver ? 你当司机有多久了？

It has been cold since last yesterday. 自从昨天以来，天气一直很冷。

The train has been gone (for half an hour). 火车开走了（半小时了）

2. have been后接动词的现在分词，为现在完成进行时

例如： He has been working in that school for five years. 他在这学校工作五年了。

（现在是否仍在该学校工作，视上下文而定。 ）

3. have been +及物动词的过去分词。表被动语态。

例如：The flowers have been watered by me since 2 hours ago.
两小时前，我已经给花浇过水了。

Answer 2

been 是 be 的过去分词，既是系动词又是助动词，have been 则是 be 的现在完成时，可以构成系表结构的完成时、现在完成进行时或被动语态的完成时。例如：
〔系表结构〕 We have been married for 14 years  我们已经结婚14年了。
〔现在完成进行时〕I have been working in the factory since then. 从那时起，我一直都在这个构成工作来着。
〔被动语态〕All the problems have been solved. 所有的问题都解决了。

Answer 3

说法不正确。have been后面跟不同的词类，语法功能各不相同。
1. 接过去分词。表示现在完成时被动语态。
2. 加名词或者形容词。表示现在完成时的系表结构。
3.

Answer 4

have been 不光表达被动，还表达现在完成进行时, 比如：

表达被动： The profiles have been widely used as a reference for decision-making.

表达现在完成进行时： They have been profiling applicants since Monday for purposes of finding the right individuals for the position.

Answer 5

只有在been的后面再加及物动词的过去分词时才表示被动。如: They have been seen to enter the library without permission.他们被看见未经允许进入图书馆。
