（2）13～19的基数词都以—teen结尾。记住三个特殊写法的。
thirteen fourteen fifteen sixteen seventeen eighteen nineteen
（3）20～90中整几十的基数词都以-ty结尾。
twenty thirty forty fifty sixty seventy eighty ninety
（4）“几十几”的表达式：整几十+连字符-+个位数
forty-one 41 fifty-two 52 sixty-three 63 基数词数词分为 ，表示数量多少的数词叫做基数词，
如one, two, three等。基数词序数词英语基数词顺口溜英语数词不难记，找出规则就容易。
零至十二形各异，一个一个单独记。
后面加teen变十几，thirteen, fifteen看仔细。
eighteen只有一个t，两个音节念清晰。
表示“几十”要加-ty, twenty, thirty 是特例。
表示数字“几十几”，连字符号别忘记。(5)一百的表示方法为one hundred或a hundred。 要表示“几百”，用具体数字加上hundred, 如five hundred(500)，注意此时的hundred是单数形式。
表示“几百几”时，要在百位数和十位数(或个位数)之间加and。如：one hundred and two(102)。 hundred, thousand(千)等的复数形式可表示不确定的数目。在这种情况下它们须用复数形式，且后面要加of。
eg：hundreds of teachers 数百位老师
thousands of students数千位学生【难点】We plant ________trees every year.(四川雅安)
A．hundreds of B．hundred of C．five hundreds D．five hundred of基数词只能修饰可数名词，要注意数词和名词在数上要保持一致。
eg：one banana 一根香蕉
five boys 五个男孩Pair work:Look at the pictures to ask and answer in pairs:A: How many …do you need?
B: I need …
A: How much… do you need?
B: …可数名词是指能以数目来计算，可以分成个体的人或东西；
不可数名词是指不能以数目来计算，不可以分成个体的概念。名词(Noun)可数名词(Countable Nouns)不可数名词(Uncountable Nouns)I would like an egg and some fish.
Would you like some eggs, Maria?
I 'd like some chicken.Grammar:可数名词和不可数名词：Grammar:可数名词有复数形式，当它的复数形式在句子中作主语时，句子的谓语也应用复数形式。可数名词前可用具体的数词来表示具体的数量。
e.g. one egg a pen
two eggs two pens
不可数名词一般没有复数形式，只有单数形式，它的前面不能用不定冠词a / an ，若要表示它的个体意义时，一般要与一个名词短语连用，相当于中文里的【数词+（ 量词）+ 名词】，其中的量词意义依与具体的名词搭配而定。
e.g. a pair of shoes a cup of coffee a bottle of water可数名词和不可数名词：Grammar:询问可数名词数量时，用How many + 可数名词复数形式。
如：How many apples do you have? 你有多少个苹果？
How many hamburgers do you want? 你想要多少个汉堡？
可数名词确定数量的表达：
1. 数目+可数名词 如： an/ one apple two apples
2. 数词+表示量的名词+of
如： a box of apples two boxes of apples.
a kilo of apples 3 kilos of apples 用第2种 +of结构表示时：可数名词始终用复数形式，数词是单数时，
表示量的名词用单数。数词是复数时，表示量的名词用复数。Grammar:How much 除了询问物品价格之外，还可以询问不可数名词数量，用How much + 不可数名词
如：How much water would like? 你要多少水？
How much rice do you have for dinner? 你晚餐吃了多少米饭？
不可数名词确定数量的表达：
数词+表示量的名词+of
如： a glass of milk two glasses of milk.
a kilo of milk 3 kilos of milk 不可数名词不能直接用数词来表示具体数量，只能用+of结构：数词是单数时，
表示量的名词用单数。数词是复数时，表示量的名词用复数。不可数名词没有复数形式。Grammar:可数名词不确定数量表达法：
用some/any/many/a lot of / lots of/ hundreds of / few/ a few等放在可数名词 如： some apples, many pictures, hundreds of teachers
不可数名词不确定数量表达法：
用some/any/much/a lot of / lots of/ little/ a little 等放在不可数名词
如：some water， much milk， lots of rice名词不确定数量的表达法：既可修饰可数名词也可修饰不可数名词的词有：
some/ any (一些)， a lot of/ lots of (许多)1.都可以加可数名词复数或不可数名词。
eg. some hamburgers some milk
2.some多用于肯定句或希望得到对方肯定回答的一般疑问句中。
eg. I need some apples.
