“Lookat+某物.”，这是提议看一看某物的句型。Lookat是“看一看”的意思。例句：看一看黑板。Lookattheblackboard.拓展：lookupat往上看lookblackat怒视；愤怒地看注意：look单独使用时，强调的是看的动作，提

醒别人注意。而lookat后接宾语，是看某

个东西的意思。例句：看！那儿有一只大狗。Look!Thereisabigdog.他们在看黑板。Theylookattheblackboard.3.Thereisanewbed.这儿有一张新床。这是一个therebe句型，“Thereisa/an+某人/某物(单数)+(地点)”，表示的意思是“某处有某人或某物”。如果be动词后面的主语是复数形式的话，那么be动词要用are。

“There+be动词+某物/某人+(地点).”

这是therebe句型，表示(某处)有某物或某人。

当be动词后面所接的是可数名词单数或不可数名词时，则be动词用is；当be动词后面所接的是可数名词复数时，则be动词用are。例句：我的包里有四支笔和两本书。Therearefourpensandtwobooksinmybag.JustreadandwriteLookatthelivingroom.ThereisaTV.Therearetwosofas.livingroomTV客厅电视armchairsofa沙发单人沙发Canyouwritethem?Let’schant谢谢大家ThankyouforlisteningUnit1Welcometomynewhome!Lesson3精通·四年级下册Lookatthekitchen.Lead-inThereisanewtable.Thereisanewfridge.桌子Newwords厨房冰箱NewwordsJusttalkLookatthekitchen,Kate.Wow!Thereisanewfridge.Look!Here’sanewtable.Andtherearefournewchairs.1.Here’sanewtable.这儿有一张新桌子。
