1.在肯定句中,当主语为第三人称单数,或单数可数名词时,have要变成相应的单数形式has.主语为其他人称和数时,则用have.
①Ihaveacat.(我有一只猫。)
②Youhaveafarm.(你有一个农场。)
③Theyhavepears.(他们都有梨子。)
④Ithasalongtail.(它有一根长尾巴。)
⑤Shehastwobigeyes.(她有一双大眼睛。)
⑥Hehasacat.(他有一只猫。)
⑦Tomhasasister.(汤姆有一个姐姐。)
2.实义动词have(有)的一般现在时的肯定句在变为否定句时,要借助助动词do和does,且have要用原形。如果主语是第三人称单数,助动词要用does,当主语是其他人称时助动词用do.
①Ihaveacat./Idon'thaveacat.
②Youhaveafarm./Youdon'thaveafarm.
③Theyhavepears./Theydon'thavepears.
④Ithasalongtail./Itdoesn'thavealongtail.
⑤Shehastwobigeyes./Shedoesn'thavetwobigeyes.
⑥Hehasacat./Hedoesn'thaveacat.
⑦Tomhasasister./Tomdoesn'thaveasister.
3.在进行疑问句转换时,要借助助动词do/does.在句首用do/does,同时将has还原成have.
肯定句用“Yes,主语+do/does.”回答。
否定句用“No,主语+don't/doesn't.”回答。
