This potato is big.T shows the word card “big” and let Ss read it.设计意图：小学四年级的学生注意力不可能集中四十分钟，所以只能用不同的游戏或教学方法去吸引他们，达到教学效果。教学A.Lets learn（1)教师播放第一遍录音，让学生边听录音边指向相应的图.（2)教师播放第二遍录音，让学生边听录音边跟读。（3)学生两人一组，进行对话。Step 3.

Tomatoes l will try. Green beans I will try.I love to eat carrots.I love to eat tomatoes.I love to eat green beans.要求学生用喜欢的表情模仿着说。2-1-c-n-j-y(3)教师拿着onions，揉揉眼睛说：But onions make me cry.让学生观察歌谣中like后的蔬菜单词和Lets learn中的单词有什么不同。启发学生说出like后的名词是以复数形式出现的。教师适当强调tomato和potato的复数形式拼写的变化，carrot的复数形式读音的变化。Step 4. Summing up总结本节课学习的单词和句子 tomato, green bean, potato, carrot及其复数形式。2.句子Look at the green beans. Theyre so long!
