主语为三单的句子：1.My sister likes milk.一般疑问：Does your sister like milk？反意疑问句：My sister likes milk,doesn't she？特殊疑问句：What does your sister like？否定句：My sister doesn't like milk.2.Tom does his homework every day.一般疑问：Does Tom do his homework every day？反意疑问句：Tom does his homework every day,doesn't he？特殊疑问句：When does Tom do his homework？否定句：Tom doesn't do his homework every day.主语为非三单的句子：3.We have a meeting on Tuesdays.一般疑问：Do you have a meeting on Tuesdays？反意疑问句：We have a meeting on Tuesdays,don't we？特殊疑问句：When do you have a meeting？否定句：We don't have a meeting on Tuesday.现在进行时的句子：The boy is flying a kite.（三单）Jane is dancing under a big tree.（三单）I am reading an English book.（非三单）His parents are doing housework.（非三单）我觉得没必要将主语是三单和非三单各造三个句子，因为相信你通过这几个句子就能明白怎样造了.。
1.Tony likes jenny.
2.Tonly has not to attend the meeting.
3.He arrives here at 8AM.

5.He does not have a laptop.
6.He works hard.
7.He enjoys the party.
