实义动词的介绍：

实义动词（实意动词）与系动词是相对的，系动词亦称连系动词（Linking Verb），作为系动词，它本身有词义，但不能单独用作谓语，后边必须跟表语（亦称补语），构成系表结构说明主语的状况、性质、特征等情况。

实义动词意思完全相反，能独立用作谓语。实义动词有及物动词和不及物动词（及物动词是指后面要求有直接宾语的动词；不及物动词指后面不需要跟宾语的动词，如果跟宾语要加介词。） 即行为动词,表示动作的动词。

Answer 2

实意动词的疑问和否定句就是用助动词do(does,did) ; have（有）的疑问和否定句可以用助动词do ,does,did，也可以用have, has,had。否定句结构是：主语+ do not / don't (doesn't / does not , did not / didn't)+ 动词原形+其他 ; 疑问句结构是： Do/Does/Did +主语+ 动词原形+其他。例如;
He works hard. Does he work hard? He does not (doesn't) work hard.
They study well. Do they study well? They don't / do not study well.
He came late. Did he come late? He didn't / did not come late.
但have（有）的疑问和否定句可以用助动词do ,does,did，也可以用have, has,had。例如：
He has a book. Does he have a book / Has he a book? He does not / doesn't have a book / He has not / hasn't a book.
They had time then. Did they have time then/ Had they time then? They didn't/did not have time then / They had not / hadn't time then.
