一、词语 1、名词
这里强调两点：不可数名词都默认为单数，所以总是用is 名词复数如何加后缀： 各种不同情况 变化方法 例词 一般情况: 1)直接加-s
book-books bag-bags cat-cats bed-beds 以s. x. sh. ch 2)结尾 加-es
bus-buses box-boxes brush-brushes watch-watches peach—peaches glass--glasses 3)以“辅音字母+y”结尾 变y为i, 再加-es family-families study--studies
4)以“f或fe”结尾 ,变f或fe为v，再加-es knife-knives 不规则名词复数
man-men woman-women policeman-policemen policewoman-policewomen mouse-mice foot-feet child-children fish-fish Chinese-Chinese

3. how often 多久一次 ,how often 是一个特殊疑问词，就频率提问。英语表示频率的词：一次：once 两次：twice 特殊 其他次数： 基数词+times 构成 例如：8次 eight times e.g. --How often do you go to the library?

4.how many 多少,how many/much 就数量提问.how many+可数名词；how much +不可数名词

易错点：Where are you come from? (错误) Where do you come from? (正确)

headache
have +病名 have measles (麻疹) have mumps (腮腺炎) 19. have to不得不

1) like sth. I like English very much
2) like to do sth.I like reading very much, but I don’t like to read now.
3) like doing sth. 动词原形
3. let’s +动词原形 Let’s (=let us) make animals. let sb. do sth. 让某人做某事 4. want想，想要
1) want sth. I want a piece of paper. 2) want to do sth. I want to watch TV. 5. 情态动词
情态动词很简单，没有人称数之变，动词原形后边站。 can 表能力；may许可； should 应该； would 愿；must必须 ，否定needn’t 换have to不得不表客观 三、 重点语法
A) 一般现在时
1. 概念：一般现在时表示经常性、习惯性的动作或存在的状态。 2. 构成：有两种构成形式
（1） be 型 句子的谓语动词只有be(am,is,are)
a 肯定句中，只出现be :I am a student．我是一名学生。 b.否定句中，要在be 后面加not，如： She isn't teacher．她不是教师。
c．一般疑问句中，要将be 放在句子开头（注意句首字母大写）， 句尾用问号，答语用Yes，主语+be．或No，主语+be +not 如：Are you ready？—你准备好了吗？ —Yes，I am．—是的，我准备好了。No, I’m not. 我没准备好。）
（2）实义动词型：句中的谓语动词为实义动词（也叫行为动词）： a．肯定句中，只出现实义动词，如：I get up in the morning．我早晨起床。
b．否定句中，要在实义动词前面加do（does）＋not，do（does）
