：Two.
T：What’s this (Show another picture. )
：It’s rice.
T：Can we count it Can we say a rice
：Sorry，I don’t know.
T：We can’t say a rice because it is an uncountable noun. Nouns include the countable nouns and the uncountable nouns. Countable nouns can be counted with number，and we usually add -s or -es to make the plural. For example，we can say an apple，two apples，three apples. Uncountable nouns can’t be counted with number，and they don’t have plurals. For example，we can say milk，rice，but we can’t say milks，rices.
T：Look at the pictures. Fill in the chart. (Show some pictures of fruits and vegetables. )
Countable nouns Uncountable nouns

1. 询问某人的喜好通常用一般疑问句：Do/Does+主语+like... 肯定答语为：Yes，主语+do/does. 否定答语为：No，主语+don’t/doesn’t. 其中do/does为助动词。
Do you like hamburgers 你喜欢汉堡包吗？
肯定答语：Yes，I do. 是的，我喜欢。
Does he like the pen 他喜欢这支钢笔吗？
否定答语：No，he doesn’t. 不，他不喜欢。
2. 名词分为可数名词和不可数名词。可数名词可以计数，分为单数和复数两种形式，指单个人或物时用单数形式，其前可用冠词a/an，基数词one等修饰；指两个或两个以上的人或物时用复数形式。不可数名词没有复数形式，其前不能用a/an，基数词或many等修饰，但可以用some，much等修饰。
3. 可数名词复数形式的变化规则：
(1)一般在词尾加-s。
book—books　　　　　　　 bag—bags
(2)以s，x，ch，sh结尾的词，一般在词尾加-es。
class—classes watch—watches
