There_____somebananasandanorangeinthebasket.3.Therebe句型表达“_______”,have\has表达“_____”“______”,两者不能同时使用.ThereisgoingtohaveaclassmeetingnextWednesday.()ThereisgoingtobeaclassmeetingnextWednesday.()辨析：therebe和have（1）therebe表达“某地有某物”,强调存在关系,不强调物的归属。Thereisabookonthedesk.（2）表达“某人拥有某物”,强调全部关系,主语多是人。Ihaveabook.【典型例题】一.根据所给汉语完毕句子。1.桌子上有一本书和两支钢笔。There_____abookandtwopensonthedesk.2.钱包里有些钱。There____somemoneyinthepicture.3.在吉姆的书包里有某些卡片。_________somecardsinJim’sbag.4.里面尚有其它的东西吗？__________anythingelseinit?5.我们学校有许多班。There_____many_____inourschool.6.树上没有鸟。There___________birdsinthetree.二、单选()1.There___anyriceinthebowl.
