Pre-reading (1) 课件展示两只鱼，一条鲸鱼和一条金鱼 teachet says: “Look, there are two fish,Which fish is bigger,the black one or the red one?” The students answer it together . Then teacher says: “Yes,the black one is bigger,and we call the black fish whale.”板书“whale”,并教读。
出示抹香鲸和虎鲸的图片,teacher says: “This is a killer whale. This is a sperm whale.” 板书并教读单词“sperm whale”和“killer whale”.学生跟读并齐读数遍。
(2) 课件呈现两种鲸鱼的长度，教师说：“The sperm whale is 15 meters.The killer whale is 8 meters. 板书并领读 meter, teach:1meter=100cm, let the students guess the meaning of “meter” Teacher sa ys 1 meter=100cm, 15meters=1500cm, 8 meters=800cm. (3) 课件呈现两种鲸鱼的重量，Teacher says: “The sperm whale is 35 tons. The killer whale is 3600kg.”板书并领读3600kg. Teachet says: “1000kg=1ton.”板书并教读“ton” Let the students guess the meaning of “ton”.Teachet says: “1000kg=1ton,3600kg=3.6tons “ (4) 出示课件Teachet says: “Look,they are sperm whale’s food. This is a squid, a lobster,a shark.” 板书并利用音节教读这几个单词。
课件呈现鱼、鸟、海豹和鲸鱼的图片. Teacher says: “They are killer whale’s food. This is a seal.”板书并教读单词seal. Teacher says : “The killer wh ale eats fish,birds,seals and even whales.”板书并领读单词even,让学生猜测even的汉语意思意思。
（设计意图：本课的生词量特别大，为了解决这一问题，先是通过对两条鱼的比较，自然的引出新单词sperm whale 和killer whale ,通过联系旧知识，让学生自己猜测本课的新单词meter和ton, 然后通过图片的展示，教读本课的新单词squid, lobster, shark, seal, 最后帮助学生通过上下文来猜测单词even的意思，帮助学生扫除下一步阅读的障碍。
