There be句型的基本用法是表示“某地(或某时)有某人(或某物)”,其形式为“Therebe+代词或名词(短语)+地点/时间状语”。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)当be动词后接两个以上主语时,be动词与最临近主语保持数上的一致。意思为"某地有某人或某物"。 There is an eraser and two pens on the desk. 桌子上有一块橡皮和两支钢笔。 (4)如果名词是不可数名词,用:How much + 不可数名词 + is there + 地点状语? How much water is there in the cup? 杯中有多少水? 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。 |
