大家好,今天小编关注到一个比较有意思的话题,就是关于thereis的问题,于是小编就整理了2个相关介绍thereis的解答,让我们一起看看吧。
一、There is/are 是there be 句型,be动词的选择要与后面的主语保持一致,如果是多个主语时,谓语动词要遵循“就近原则”。
二、There be句型的基本用法是表示“某地(或某时)存在有某人(或某物),而并非某地(某人、某物或某时)拥有什么东西”,其形式为“There be+代词或名词(短语)+地点/时间状语”。(其实质句式为倒装句)这里there是引导词,没有词义,be是谓语动词,代词或名词(短语)是主语。be要与主语保持人称和数的一致。否定句是在be后加not;一般疑问句是将be放在句首;反意疑问句中的简短问句是由“be(或其否定式)+there”构成。例如:
1.There is a desk and two chairs in the room.
(紧挨着be动词的主语是a desk,是单数,故be的形式要用is)
2.There aren't two chairs and a desk in the room.(否定句)
3.Is there anything wrong with your ears?(Yes,there is/No,there isn't.)
4.There wasn't a meeting yesterday,was there?(反意疑问句)
除此之外,还有一个重要句式“有某人在做某事”,要用“There be+sb.+doing sth.+地点/时间状语”。例如:
There are several children swimming in the river.河里有几个孩子在游泳。
there is 与there are 均表示引导“有…”的句型。前者there is后只可跟表示单数的词,而后者there are 后只可跟表示复数的词。例子:there is one student in the class room now.现在教室里面只有一名学生。
there are three students in the class room now.这会教室里面有3个同学
there is, there are都是there be句型,均表示“有”。区别在于其后接的名词为单数还是复数。若为单数,则使用there is,比如树上有一颗苹果: There is an apple in the tree. 若为复数,则使用there are, 例如书上有好多苹果: There are so many apples in the tree.
A. There与be中间可插入一些表推测的情态动词、表时态的短语(如和将来时be going to will、现在完成时 havehas + pp. ) 例如:
1) There must be a pen in the box.
2) Is there going to be a dancing party tonight?
3) There is not going to be a meeting tonight.
4) There has been a big tree on the top of the hill.
到此,以上就是小编对于thereis的问题就介绍到这了,希望介绍关于thereis的2点解答对大家有用。
