Be动词包括： is, am, are, was, were2. 实义动词：某个实际做出来的动作词语，如： swim, wash, do, go, buy, fly, sleep等等。3. 要注意的是：小学阶段，当一个句子出现了be动词，那就没有实义动词，两者是“水火不容”的，只能二选一。1) Be动词后面可以加名词:I am a student. My father is an engineer.2） Be动词后面加形容词

5、： I am tired. You are very happy. They were very excited. He is tall/short/strong/thin.3） 实义动词后面不加形容词，加名词或动名词。正确： I went to the park last Sunday. 错误： I was went to the park last Sunday. （×） 正确：They ate good food at the restuant last night. 错误： They were ate good food at the restuant last night.
