可数名词 不可数名词
定 义 可以用来计数的名词。 不可以直接用来计数的名词。
修 饰 词 前面可以用不定冠词a / an，数词或 some, many 等词修饰。 前面不能加不定冠词、数词或many 等，但可以用some, a little, much 等词来修饰。若要表示数量的多少时，须与表示量的名词 连用。例如：a bowl of rice, three pieces of bread。
作主 语 可数名词作主语时，谓语动词的单、复数与主语 的单、复数须保持一致。 不可数名词作主语时，谓语动词用单数形式。但如果不可数名词前有复数名词短语修饰时，谓语动词须用复数形式。例如：Two cups of tea are on the table.
提 问 对可数名词的数量提问用how many。 对不可数名词的数量提问要用 how much,但对不可数名词前表示数量的名词提问时要用 how many。例如：I bought four bottles of milk.对 bottle的数量提问就要用 how many。
可数名词 不可数名词
1.只能修饰可数名词的词语有:
many, many a(n), a good/great many, a (great/large) number of, scores of, dozens of等。
2.只能修饰不可数名词的词语有:
much, a great deal of, a great/large amount of等。
3.既能修饰可数名词又能修饰不可数名词的词语有:
a lot of, lots of, plenty of (以上三个词语后谓语动词的数以of 后的名词的单复数而定), lots of, a lot of 或plenty of; 正式文体中常用 a great many, a (large) number of, a great deal of, scores of 或 dozens of 等。
但若肯定句中有too, so, as, very或how 等词修饰时,则必须使用 many, much。
二、易错点：
How many与how much
how many和how much都用来对“数量”进行提问，意为“多少”，前者主要用来对可数名词的数量进行提问，后接可数名词复数；后者主要用来对可数名词的量进行提问，后接不可数名词。另外，how much还可以直接用于询问价格。如：
---How many weeks are there is a year 一年有多少个星期？
---There are fifty-two.有五十二个。
---How much is your backpack 你的背包多少钱？
---It’s thirty yuan. 三十元。
---How much milk is there in the glass 杯子里有多少牛奶？
---There is only a little. 只有一点。
Grammar
(一)祈使句
1、意义：祈使句表示请求、命令、警告、劝告、禁止等；肯定祈使句常以动词原形开头;否定祈使句常以Don′t、Never 等表示否定的词开头。祈使句常省略主语you.
2、类型
1）Do 型祈使句
肯定结构：实意动词原形+其他
否定结构：Don′t +实意动词原形+其他
eg:给我一本书。 进来。 别放弃。
2)Be型祈使句
肯定结构：Be+形容词
否定结构：Don′t + be +形容词
eg:安静点。 快一点。 别害羞。
3）Let型祈使句
肯定结构：Let sb. do sth 让某人做某事
否定结构：
① Don′t let sb. do sth 不要让某人做某事
② Let sb. not do sth 让某人不要做某事
4）No 型祈使句（表示否定含义）同义句
结构：No + n/v-ing. 禁止...
eg:禁止吸烟 禁止拍照 禁止大声喧哗
5)其他结构：
① 直接用名词、副词、动词
eg:救命！ 快点儿！
② 名词+副词
eg:请举手！
3、注意：
1）为了使祈使句的语气更加委婉客气，可在句首或句末加上please；当please放在句末时，要跟前面的句子用逗号隔开。
eg:请进！ 请照看好你的狗！
2）有时为了强调，可在动词前加do或将祈使句的主语you写出来。
eg:You shut up ! 你闭嘴！
Do let me go.请务必让我去。
4.祈使句的答语
祈使句的答语常表示将要发生的动作，所以答语为：Yes, I will. / No, I won't.
eg: ①--Please remember to finish your homework.
-- Yes,I will .
②--Don′t be late fot school again.
--Soory, I won′t.
5.祈使句的反义疑问句
1） will you “可以吗”
eg: Please be quiet , will you
eg: Don't talk in class , will you
2）以let′s 开头的祈使句，用 shall we 提问；
以 let us 开头的祈使句，用will you 提问。
为帮助大家理解并掌握祈使句的“四兄弟”，请记住下面的“秘笈”：祈使句，四兄弟，V，B，L还有D。共同特点无主语，只用动词就可以。表示请求或命令，加上please更客气。Don’t开头否定句，它表禁止没问题。怎么样？现在大家该对我们祈使句家族了解了吧！
