参考答案：be 为连系动词、系动词 ，表示状态，不能跟动词原形，一般式为am/is/are ,过去式为was/were ，一般将来时am/is/are+going to +动词原形 。例如：I am a bus driver . I was ten years old last year. He is a worker .She was ill last week . We are students. They were at home llast night . I am going to go home tomorrow . Alice is going to play football next sunday morning . They are going to do some shopping soon .
