鯨的體型是世界上存在的動物中最大的，鯨是終生生活在水中的哺乳動物，對水的依賴程度很大，以致它們一旦離開了水便無法生活，鯨形狀像魚，鼻孔在頭的上部，用肺呼吸。體長可達(dá)三十米，是現(xiàn)在世界上最大的動物。對于鯨魚你知道多少？

鯨為適應(yīng)水中生活，減少阻力，它們的后肢消失，前肢變成劃水的漿板。身體成為流線型，酷似魚。因而它們的潛水能力很強(qiáng)，小型齒鯨可潛至100-300米的水深處，停留4-5分鐘，長須鯨可在水下300-500米處待上1小時，最大的齒鯨--抹香鯨能潛至千米以下，并在水中持續(xù)2小時之久。Togivestudentspracticeinusingthetargetlanguageinwriting.Toreviewthekeyvocabularyandfunctionspresentedinthisunit.ObjectivesSelf-learning1.Readthesentencesin3aonPage55andfinshtheexercise.2.Haveacheck.Readthefollowingwordsandphrasesaboutwhales.Puttheminthecorrectplaceinthechart.1.Humanscatchwhalesformeat,fatandoil2.Eatsmallfishandothersealife3.Jumphighoutofthewater4.Rulesonwhaleprotection5.Huge6.Waterpollution3a7.Liveinthesea8.Somekindshaveteeth9.Learnmoreaboutwhales10.Stopputtingrubbishintothesea11.Singsongs12.WhalepartssoldtomakethingslikescandlesandsoapWhatdotheylooklike？Wheredotheylive?Whatdotheyeat?Whatcantheydo?Whydosomeofthemhavetobeprotected?Howcanweprotectedthem?587231116124910
