2、别的人、事物、地点等专有的名称，如： jim, china 专有名词的第一个字母要大写，如：beijing, new york 名词按其所表示的事物的性质分为可数名词和不可数名词。 可数名词：可以用数目计算，有单数和复数两种形式，如：an apple, two apples, a car, some cars 不可数名词：一般无法用数目计算，没有复数形式，且不用不定冠词a/an修饰，如：water, milk, meat, tea, bread, rice 单数名词变复数名词的规则如下表： 注：少数名词的复数是不规则的，如： manmen womanwomen childchildren 表示

3、民族的名词，有的在词尾加 s ，如： an americanthree americans 有的单、复数形式相同，如： a chinesefour chinese a sheepthree sheep a deerfive deer 2. 冠词 冠词是一种虚词，不能单独使用，只能和一个名词一起使用，并帮助说明此名词。冠词有两类，即定冠词the 和不定冠词a/an。 不定冠词 常表示“一”的概念，有两种形式：a和an。a用在辅音音素开头的单数可数名词前，如：a book, a pen；an用在元音音素开头的名词前，如：an apple,an orange,an egg。 定冠词the 常表示“这

4、个”“那个”“这些”“那些”的概念，the在元音音素前读，在辅音音素前读 ，如：the moon, the evening。 eg. do you have an english book? yes, but the english book is broken. there is a chicken in the picture. we cant see the sun at night. the browns are going to the park this sunday. shanghai is in the east of china. 3. 形容词 用来修饰名词，表示人或事物的特

5、征，在句中可以作定语、表语、宾语补足语。 如： its a sunny day today. lets go to the park. this book is good. its very nice of you to help us. 常见形容词的同义词与近义词： largebig 大的 gladhappy/pleased 高兴的 cleverbright 聪明的 illsick 病的 finewell 好的 常见形容词的反义词和对应词： bad（坏的）good（好的） big（大的）small（小的） busy（忙的） free（空闲的） dry（干的）wet（湿的） same（相同的）

6、different（不同的） empty（空的）full（满的） cold（寒冷的）hot（热的） open（开着的）closed（关闭的） poor（穷的）rich（富的） 4. 副词 用来修饰动词、形容词、其他副词或全句，在句中作状语或表语。 eg. now he is back in new york again. 现在他又回到了纽约。 mike is a good student. he often does his homework carefully. 副词一般分为七大类： 时间副词： now, often, then, early, ago, before 地点副词： here,

7、 there, out, above, up, down 方式副词： hard, well, badly, fast, slowly 程度副词： very, much, still, almost, too, so 疑问副词： how, when, why, where 关系副词： when, where, why 连接副词： now, where, why often 等表示“频率”的时间副词，总被放在句子中间，又称“中置副词”。这类副词有 always（总是）、 usually（通常）、sometimes（有时）、ever（曾经）、never（从不）等。 “中置”规律： 放在单个的 be

8、动词之后； 放在单个实义动词之前； 谓语动词为多个词时，放在第一个助动词或情态动词之后。 如： you are always late for school. 你总是上学迟到。 i usually go to school by bike. i never see that book. he often helps other students. he goes to work on foot sometimes. 5. 比较等级 在进行比较的时候，形容词和副词有原级、比较级和级三种形式。 规则形容词和副词的比较级和级加 -er或-est。 （1）不规则变化的形容词和副词如下： betterb

9、est wors worst （许多）many/muchmoremost （几乎没有）littlelessleast （远的）farfartherfarthest （老的，旧的）old （2）三种句型 原级句型： as形容词/副词as，表示“和一样”；否定句式：not as/so 形容词/副词as，表示“和不一样”。 eg. i think kate does just as well as ann. if you like the chicken, you may have as much as you can. i dont like the film. its not so intere

11、l 越来越漂亮 c. the比较级, the比较级，表示“越就越”，说明随着前边条件的变化，后边的结果也发生变化。 eg. the more she eats, the fatter shell be. 她吃得越多就会越胖。 the more, the better. 越多越好。 级句型： 主语谓语（the）形容词或副词的级in/of 注：级前一般要用the，如： he is the most careful student. 但在副词级前the可以省去，如：he writes（the）most carefully in his class. this kind of cake is the

14、, are you?/who are you? (7)在回答this或that作主语的疑问句时, 要用it代替this或that。 如： is this a notebook? 这是笔记本吗?yes, it is. 是的，它是。 whats that? 那是什么?its a kite. 是只风筝。 【篇三】 unit5. do you have a soccer ball? 句型: do you have a tv? yes, i do/no, i dont. do they have a computer? yes, they do./no, they dont. does he have

17、s, go-goes, 以辅音字母加y结尾，把y改为i, 再加es study-studies 3, do/does 叫做助动词(语法需要加上去翻译部出来的动词)时，后面接动词原形， does he like reading? she doesnt like reading. she doesnt do her homework. 但是如果做实义动词(能翻译出来意思的动词)呢，遇到主语第三人称单数就要起变化。 she does her homework. 4，have的第三人称单数为 has. 5, let sb do sth 让某人做某事 (sb代表人，如果是代词用宾格，do代表动词原形)
