1、Unit8Isthereapostofficenearhere?东林乡中学郑树禹Let'swatchandlearn!therebe句型定义therebe构成的句子称为“存在句”。此句型构成形式一般为“therebe+某人/物+地点/时间”，意为：在某地有某物（或某人）。therebe句型结构“What’s+表示地点的介词短语”用therebe句型来回答。—What’sonthedesk?—Thereare5eggsonthedesk.注意：询问的时候，be动词只能用单数is，而回答时需视情况而选用单复数。易错点1a.Thereis+

2、单数可数名词不可数名词Thereisabookonthedesk.桌子上有一本书。Thereissomewaterinthebottle.瓶子里有些水。用法Therebe就近原则：若句子中有几个并列主语时，be动词的形式要与离其最近的一个主语在人称和数上保持一致。1.Thereisagirlandtwoboysunderthetree.易错点3have/has与主语是“所属关系”，强调的是“拥有，占有”。therebe表示“存在关系”，强调某地“有”某物，（某地存在）Therebe与have的区别【典例1】—What______on
