Be动词包括：is,am,are,was,were
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。
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。
Be动词后面可以加名词:
Iamastudent.
Myfatherisanengineer.
Be动词后面加形容词：
Iamtired.
Youareveryhappy.
Theywereveryexcited.
Heistall/short/strong/thin.

实义动词后面不加形容词，加名词或动名词。

正确：IwenttotheparklastSunday.
错误：IwaswenttotheparklastSunday.（×）

正确：Theyategoodfoodattherestuantlastnight.
错误：Theywereategoodfoodattherestuantlastnight.（×）

只有一种情况两者必须同时存在：那就是现在进行时:
如：IamwatchingTVnow.
Look,Maryissweepingthefloor.
Listen!Thegirlsaresingingintheclassroom.
