最近be动词和实义动词老混淆，有什么方法可以区分吗，今年六年级，下个星期日就考试了，我英语差啊！怕怕
详细一点
1. be动词属于系动词, 在句子中主要表现为三种形式：am is、are。后面往往接形容词或名词做表
语。如：
(1)I’m young. (young形容词做表语)
(2)He is a boy.( a boy名词做表语)
含有be动词的句子在进行否定、疑问句变化时，都要在be动词上变化。
(1)变为否定句：主语+be+ not+其他。即，直接在be后not.
①I’m a Chinese boy.(变为否定句)
②You are good. (变为否定句)
③He is strict with us. (变为否定句)
④She is from America. (变为否定句)
以上四个句子中都含有am、 is或are，变否定句时，直接在am 、is、are后面加上not.即：
①I’m not a Chinese boy.
②You are not good.
③He is not strict with us.
④She is not from America.
(2)变为一般疑问句：Be+主语+其他？即把be动词提到主语的前面。注意：当肯定句主语为第一人称I和We时，变一般疑问句要变为第二人称，be动词也要相应的变为are.同样肯定句中的my和our 也要变为your.
① I am a boy. (变为一般疑问句)→Are you a student?
② We are good friends. (变为一般疑问句)→Are you good friends?
③ She is from America. (变为一般疑问句)→Is she from America?
④ He is strict with us. (变为一般疑问句)→Is he strict with us?
(3)变特殊疑问句：一般的要求为“对划线部分提问”，即用特殊疑问词代替划线的部分，后接省略划线部分的一般疑问句（一般不再出现划线部分）。如：
① I’m well.（对划线部分提问）→How are you?
②She is from America. （对划线部分提问）→Where is she from?
3、实义动词，也叫行为动词。就我们现在所学的内容来讲，实义动词所在的句子中一般不存在be动词。也就是在含有实义动词的句子变否定句或疑问句时，一定不能用be动词。那么，实义动词究竟怎样用呢？正如be动词随着主语的变化可变为am、is、are一样，在一般现在时态的句子中，实义动词在肯定句中，也要随着主语的变化而变化。当主语为第三人称单数he,she, it时，实义动词要变为相应的第三称单数；当主语为非第三人称单数I, you(你), we,you(你们) they时，实义动词要用动词的原形。而在变否定句和疑问句时，不能直接在动词上变，而是要借助另一类动词：助动词do、does。
（1）肯定句：
①I have a blue pen.
②He has a brother.
③ She wants to be an actor.
④ They like to play football.
(2)否定句：主语+don’t/doesn’t+动词原形。其中do/does为助动词，是来帮助实义动词构成否定或疑问句的，但加了
do/does后，其后面的动词必须用动词原形。
①I have a blue book.（变为否定句）
→I don’t have a blue book.
②He has a brother. （变为否定句）
→He doesn’t have
③She wants to be a teacher.（变为否定句）
→She doesn’t want to be a teacher.
④They like to play basketball.（变为否定句）
→They don’t like to play basketball.
(3)一般疑问句：Do/Does +主语+动词原形+其他？句中加了do/does后，其后面的动词还是必须用动词原形。
①I have a blue backpack.(变为一般疑问句)
→Do you have a blue backpack?
②He has a sister. (变为一般疑问句)
→Does he have a sister?
③My brother does his homework before supper. (变为一般疑问句)
→Does your brother do his homework before supper?
④She wants to be a teacher. (变为一般疑问句)
→Does she want to be a teacher?
⑤They like to play basketball. (变为一般疑问句)
→Do they like to play basketball?
(4)特殊疑问句：特殊疑问词+一般疑问句？
① Your sister likes English best because it’s interesting. (对划线部分提问)
→Whydoes your sister like English best?
② He does his homework before supper. (对划线部分提问)
→Whendoes he do his homework?
注意：当含有and引导的短语在句中做谓语或宾语，我们把这类句子变否定句时，必须把and变为or.如：
(1)He can swim and dance. （变为否定句）
→He can’t swim or dance.
(2)My father likes English and math. （变为否定句）
→My father doesn’t like English or math.
语。如：
(1)I’m young. (young形容词做表语)
(2)He is a boy.( a boy名词做表语)
含有be动词的句子在进行否定、疑问句变化时，都要在be动词上变化。
