be (are is am )动词的意思有;是。 存在 , 发生 逗留等意思 举个例子;l am in the classroom.可不可以改成; l am classroom.我在教室 可不可以这样改
再举多一些例子,谢了
追答be 作为系动词,后跟表语。表语可由很多不同的词类和短语甚至句子来担任:
1. He is a student.
2. He is tall.
3. He is at home.
4. School is over.
5. My job is teaching Englsh. (动名词作表语)
6. The film is moving. (现在分词作表语)
7. We were moved. (过去分词作表语)
8. You work today is to clean the blackboard. (不定式作表语)
9. What I want to say is that the verb BE is very useful.
10 I am telling you the usage of BE. am是助动词,与telling一起构成谓语动词的现在进行时态,
11. I was told that you came from Beijing. 被动语态。
