There

+某物/某人+某地表示：某地有某物或某人Thereisa/an＋单数可数名词＋地点不可数名词＋地点一、therebe句型结构Thereare＋名词复数＋地点1:There

二、就近原则there是个近视眼；近水楼台先得月。就近原则：be动词离着哪个名词近，就根据哪个名词的数量来变化（单数is复数are，不可数名词用is）be动词单复数形式要跟therebe之后的第一个保持一致。1.There______abookandsomepensinthebag．A.beB.areC.isD.have2.There______twosofasandatableinherroom．A.haveB.isC.areD.was3.There______somebeefandapplesonthetable.A.beB.areC.isD.have不可数名词Therebe句型两种“变身”变否定句变一般疑问句三、结构转换Therebe句型的否定形式1.Thereisaknifeinthekitchen.否定:Thereis
