大家好，我是小跳，我来为大家解答以上问题。实义动词是什么意思英语，实义动词是什么很多人还不知道，现在让我们一起来看看吧！
1、实义动词，也叫行为动词。
2、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。
3、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。
4、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，实义动词在肯定句中，也要随着主语的变化而变化。
5、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。
6、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。
7、 （1）肯定句： ① I have a blue book. ② He has a brother. ③ She wants to be a teacher. ④ They like to play basketball. (2)否定句：主语+don’t/doesn’t+动词原形。
8、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。
9、 ① I have a blue book.（变为否定句）→I don’t have a blue book. ② He has a brother. （变为否定句）→He doesn’t have ③ She wants to be a teacher. （变为否定句）→She doesn’t want to be a teacher. ④ They 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。
10、 ① I have a blue book.(变为一般疑问句)→Do you have a blue book? ② He has a brother. (变为一般疑问句)→Does he have a brother? ③ My brother does his homework before supper. (变为一般疑问句) →Does your brother do his homework before supper? ④ She wants to be a teacher. (变为一般疑问句)→Does she want to be a teacher? ⑤ They 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) →Why does your sister like English best? ② He does his homework before supper. (对划线部分提问) →When does 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.。
