【教学过程】：
Step1. Warming up.
1.Free talk
T: This morning, I had some noodles and some milk. They are delicious. Do you like nice food?
What do you like eating?
What do you like drinking?
S: I like…
（设计意图：以食物导入，师生之间谈论喜欢的食物和饮料，这样可以拉近距离，活跃气氛，并为新课的教学做好铺垫。）
2.Look at the learning aims.
（上课伊始，让学生了解本课的教学目标，让学生们带着明确的目标学习。）
Step 2. Revision
1. Let’s judge about Mike’s diet.
T: Please listen and judge the sentences according to Story time. If the sentence is true/false, please do it like this.(Act)
(以“Listen and do” 的游戏形式，先听，然后判断Mike的饮食。)

(1) Let’s learn
T: Now look at the sentences. What can you find?
S: A lot of rice, a lot of noodles, some fish and some vegetables.
T: Can you find the rules?
(通过对Mike和杨玲饮食的chant，让学生自己发现语言现象：a lot of、some既可以修饰可数名词，又可以修饰不可数名词)
(2) Let’s compare
T: How about “a few” and “a little”? Pay attention to the words after “a few” and “a little”. Are they countable or uncountable? Let’s compare. Can you find some rules about “a few” and “a little”.

（设计意图: 运用游戏和首字母填空两种形式复习Story time，激发学生的积极性，并适时提高要求，让学生来提出合理的建议，使学习的内容基于文本，又高于文本。以chant的形式，感知理解语法。用游戏的形式巩固语法。）
