have的三单新式
动词have作为"有"使用时,表示"某人(物)有……"用于第一、二人称单数I、you和复数主语,其单数第三人称形式为has,用于第三人称单数he、she、it和单数主语.
肯定句：主语＋have / has＋宾语.例如：
1.I have an English book.
2.Lily has a dog.
3.They have many friends.
另外,have、has作为"有"使用时,在英国英语和美国英语中稍有差异.
在英国英语中,have=have got,has=has got,在实际应用时,got常省略.
否定句:在have、has后直接加not.主语＋have not / has not+宾语.例如：
1.You have not a red car.
2.She has not a new bike.
3.Lily and lucy have not a big family.
一般疑问句:把have、has移到句首,在回答时仍用have / has.Have / Has+主语＋宾语?例如：
1.Has she a new bike?
Yes,she has.(No,She hasn't.)
2.Have they many friends?
Yes,they have.(No,they haven't.)
3.Have Lily and lucy a big family?
Yes,they have.(No,they haven't.)
特殊疑问句：用"特殊疑问词＋have / has+其它".例如：
Who has an English book?
What have Lily and Lucy got?
在美语中,含有have / has的句子要借助于助动词变为问句和否定句,但has要变为have.在作回答时也要用do或does的形式.
否定句中,用"主语＋don't / doesn't+have+宾语".例如：
1.I don't have an English book.
2.She doesn't have a new bike.
一般疑问句中,用"Do / Does+主语＋have+宾语".例如：
1.Do you have an English book?
Yes,I do.(No,I don't.)
2.Does she have any friends?
Yes,she does.(No,they doesn't.)
特殊疑问句中,用"特殊疑问词＋do/ does+主语+have+其它".例如：
1.What do they have?
2.How many friends does Lucy have?
当特殊疑问词作主语时,直接用"特殊疑问词＋have / has+其它".例如：
Who has an English book?
