鲸的体型是世界上存在的动物中最大的，鲸是终生生活在水中的哺乳动物，对水的依赖程度很大，以致它们一旦离开了水便无法生活，鲸形状像鱼，鼻孔在头的上部，用肺呼吸。体长可达三十米，是现在世界上最大的动物。对于鲸鱼你知道多少？

鲸为适应水中生活，减少阻力，它们的后肢消失，前肢变成划水的浆板。身体成为流线型，酷似鱼。因而它们的潜水能力很强，小型齿鲸可潜至100-300米的水深处，停留4-5分钟，长须鲸可在水下300-500米处待上1小时，最大的齿鲸--抹香鲸能潜至千米以下，并在水中持续2小时之久。Readthefollowingwordsandphrasesaboutwhales.Puttheminthecorrectplaceinthechart.1.Humanscatchwhalesformeat,fatandoil2.Eatsmallfishandothersealife3.Jumphighoutofthewater4.Rulesonwhaleprotection5.Huge6.Waterpollution3a7.Liveinthesea8.Somekindshaveteeth9.Learnmoreaboutwhales10.Stopputtingrubbishintothesea11.Singsongs12.WhalepartssoldtomakethingslikescandlesandsoapWhatdotheylooklike？Wheredotheylive?Whatdotheyeat?Whatcantheydo?Whydosomeofthemhavetobeprotected?Zx，xkHowcanweprotectedthem?587231116124910Writeaparagraphaboutwhalesandwhytheyneedtobeprotected.Usetheinformationin3a.Thenmakeaposter.3bWhalesare…Theylivein…Theyeat…Theycan…Oneinterestingfactis…Anotherinterestingfactis…Somekindsofwhalesareindangerbecause…Weshouldprotectwhalesfrom…Ithinkpeopleshould/shouldn’t…Anserswillvary.Samplewriting:Walesarehuge.Theyliveinthesea.Theyeatsmallfishandothersealife.Theycansingsongs.Oneinterestingfactiswhalescanjumphighoutofthewater.Somekindsofwhalesareindangerbeacausehumanscatchthemformeat,fatandoil.Weshouldprotectwhalesbymakingrulesonwhaleprotection.IthikpeopleshouldlearnMoreaboutmorewhales.clever--cleverer--cleverest
