大象是现存世界最大的

陆栖动物，主要外部特征为柔韧而肌肉发达的长鼻和扇大的耳朵，具缠卷的功能，是象自卫和取食的有力工具。象肩高约2米，体重3～7吨。非洲象耳大，体型较大，体重较重。亚洲象耳小，身体较小，体重较轻。

大熊猫最奇特的一点是新生儿在出生时相当的不成熟，体重仅是它母亲体重的0.1%，平均为145克左右，约为成年的千分之一。照顾孩子是一项非常艰巨的任务，通常历时18个月，有时长达两年，直到她的下一个孩子出生。1aComparefactsaboutthesetwoanimals.Usethelanguageintheboxtohelpyoumakesentences.Elephant—is350cmtall—weighs5,000kilos—eats150kilosoffoodadayPanda—is150cmtall(standingontwolegs)—weighs100kilos—eats10kilosoffoodadayExamplesentence:Thiselephantweighsmanytimesmorethanthispanda.(200cmtaller/shorter,weighmuchmore/less,eatmuchmore/less,eatmanytimesmore)Elephantis350cmtallweighs5,000kiloseats150kilosoffoodadayTrytodescribetheelephantusingtheinformationabove.Forexample:1.Thiselephantis350cmtall.2.Itweighs5,000kilos.3.Iteats150kilosoffoodaday.Pandais150cmtall(standingontwolegs)weighs100kiloseats10kilosoffoodadayTrytodescribethepandausingtheinformationabove.Forexample:1.Thepandais150cmtallwhenitisstandingontwolegs.2.Itweighs100kilos.3.Iteats10kilosoffoodaday.Thiselephantis200cmtallerthanthispanda.Thiselephantweighsmuchmorethanthispanda.Thiselephanteatsmuchmorethanthispanda.Thiselephanteatsmanytimesthanthispandaaday.1bListenandcheck(√)thenumbersyouhear.____100____16____20____50
