1.含有be动词am/is/are的句子,变否定时,直接在be动词后加not；变一般疑问句把be动词提前.举三个例子：
She is making a toy.She is not making a toy.
Is she making a toy?Yes,she is.No,she isn't.
I am laughing.I am not laughing.Am I laughting?Yes,I am.No,I'm not.
You are walking fast.You are not walking fast.
Are you walking fast?Yes,you are.No,you aren't.
那么在你所写的句子中：He is crying.They are jumping now.The teachers are speaking.Tom is playing a game.His mother is cooking.We are singing here.The students are sleeping.都可以按上面来变化.
2.在没有be动词的句子中:变否定时,要借助do或does,当主语为it,he she等单数第三人称时,用does,其他用do；变一般疑问句,把do或does提前.举几个例子：
I make my bed.I do not make my bed.
Do I make my bed?Yes,I do.No,I don't.
They watch TV.They do not watch TV.
Do they watch TV?Yes,they do.No,they don't.
She loves Mary.She does not love Mary.注意：用了does,love的后面就没有s了.
Does she love Mary?Yes,she does.No,she doesn't.
He studies English well.He does not study English well.
Does he study English well?Yes,he does.No,he doesn't.
Jack runs slowly.Jack does not run slowly.
Does Jack run slowly?Yes,he does.No,he doesn't.
那么在你所写的句子中：They listen to me.The girls like singing.We often dance here.The boys clean the room.I like maths.We play basketball.They write to her.The boys feel happy.------这些句子要用助动词do来构成否定和疑问句.
Tom speaks English.She sees me every day.His father works hard.My mother goes home late.She sleeps well.The boy carries a book.Lucy gets off the bus here.---------这些句子要用does来构成否定和疑问句.注意：用了does后,句中动词的“单三形式”要改为原形,也就是把后面的s或es去掉.
