可数名词与不可数名词：
可数名词：是指可以计数的名词，有单复数之分。
表示单个概念时用单数形式，单数可数名词不能单独使用，它必须与冠词、代词等修饰词连用；表示两个或两个以上概念时用复数形式。在前面我们已经讲到过可数名词变复数的变化规则，在这里就不重复了。
如：an apple 一个苹果；three girls 三个女孩
【注意】名词中有一类名词是集体名词，表示一个群体的人或物，这类名词本身就表示复数概念。
如：family 家人；class 班级；people 人
不可数名词：是指不能计数的名词，它没有复数形式，不能与不定冠词连用，但可以与定冠词the连用。
如：milk 牛奶；bread 面包；rice 米饭
【拓展】还有一类名词，既可以作可数名词，也可以用作不可数名词，但所表达的意义不同。
如：fruit 水果→fruits 各种水果
chicken 鸡肉→chickens 小鸡

一、动词like在一般现在时中的用法
like意为“喜欢”，用于一般现在时中有两种形式：like和likes。当主语为第三人称单数时用likes，其他人称则用like。如：
I like ice -cream. 我喜欢冰淇淋。
She likes English. 她喜欢英语。
变成否定句或一般疑问句时，要借助于助动词do/does，但likes必须恢复成原形。如：
She doesn’t like English. 她不喜欢英语。
—Does she like English 她喜欢英语吗？
—Yes, she does./ No, she doesn’t. 是的，她喜欢。/
不，她不喜欢。
【拓展】特殊疑问句
What does she like？
她喜欢什么？
Language Points
Great works are performed not by strength but by perseverance
二、名词的数
1. 可数名词
可以计数的名词叫可数名词。可数名词一般有单数和复数两种形式。
可数名词复数形式的规则变化：
类别 构成方法 示例
一般情况 加-s bed—beds
以s, x, ch, sh等结尾的词 加-es box—boxes watch—watches
以辅音字母加y结尾的词 变y为i再加-es strawberry—strawberries
以f, fe结尾的词 变f, fe为v再加-es leaf—leaves
直接加-s roof—roofs
以o结尾的词 加-es tomato—tomatoes
加-s photo—photos
以 o结尾的名词变复数加 -es的有：英雄(hero)爱吃西红柿(tomato)和土豆(potato)
Language Points
Great works are performed not by strength but by perseverance
2. 不可数名词
在英语中，有些名词不能用具体的数目计算，我们称其为不可数名词，如：rice，milk，meat，bread等。不能在前面直接加数词或a/an，也不能在词尾加- s或- es，但some和any可直接放在其前面。如：
some bread 一些面包
some rice 一些米饭
chicken n. 鸡肉 (不可数)
鸡 (可数)
3. 某些名词既是可数名词，又是不可数名词，但有时意义不同。如：
