there be句型的用法
定义:there be句型表示某处有某人或某物。
知识结构 用法剖析 例句
there be句型中be的判定 根据be后的第一个名词确定用is或are。若be后的第一个名词是单数可数名词或不可数名词,用is;若be后的第一个名词是复数可数名词,则用are。there is可以缩写为there’s; there are可以缩写为there’re。 There is a pen and some books on the desk. 课桌上有一支钢笔和一些书。 There are some books and a pen on the desk. 课桌上有一些书和一支钢笔。
there be 句型的否定句 直接在be后加not。其中there is not可缩写为there isn’t; there are not可缩写为there aren’t。 There aren’t students in the classroom now. 现在教室里没有学生。
there be句型的一般疑问句及其答语 Is there… 肯定回答:Yes, there is. 否定回答:No, there isn’t. —Is there a book on the desk 课桌上有一本书吗 —Yes, there is./No, there isn’t. 是的, 有。/不, 没有。
Are there… 肯定回答:Yes, there are. 否定回答:No, there aren’t. —Are there any boys in your group 你们小组有男生吗 —Yes, there are./No, there aren’t. 是的, 有。/不, 没有。
巧学妙记
there be, 有特点, 主语放在be后面。多个主语并列时, be随最近的主语变。
变疑问, 很简单, 将be提到there前; 变否定, 也不难, be的后面not添。
肯定句中用some, 疑问否定any换。介词短语表地点, “有”表存在记心间。
