Step 3 教师引导、学生自我小结：

1. several 形容词“几个的、数个的”“a few/some”修饰或代替可数名词复数。

e.g. There were several hundred people there. 那有好几百人。

我们中的几个人溜冰一整个上午。

________ of us _______ _______ _______ for the wh ole morning.

2.如何使用whole与all

Whole是形容词，意味“全部的”，修饰名词时，前一般有数量词或定冠词；既有定冠词又有数量词时，whole常位于定冠词后数量词前。

E.g. 三整天 three _______ days = the _______ three days

*whole与一般形容词一样，将冠词、物主代词放在其前面，而all须把限定词放在其后。

________ my life = my _______ life The _______ school = _______ the school 所有的钱 all the money，不能说the whole money.

*whole一般不能修饰不可数名词或物质名词，而all也可以。

其结构为： all the/one’s + 不可数名词

数词 + whole + 可数名词复数

翻译下列短语：

1. 所有他的光碟 _______ _______ _______

2. 整个下午 _______ _______ __________

3. 所有的钱 _______ _______ __________

4. 整个家庭 _______ _______ __________

5. 整整五个小时 _______ _______ _______

_______ _______ _______ _______

3. every 和 each的用法

e.g. For every hour they skate, each st udent raises ten yuan for charity.

他们每滑一个小时，每个学生可为慈善机构募捐十元钱。

句中every和each都有“每一个”之意，但every指三者或三者以上的每一个，着重于整体，含有包括全体的意思。every只用作形容词，作定语修饰名词，不能用作代词，没有every of…这种形式；each指两个或两个以上中的每一个，着重于个体，既可作形容词，也可作代词。every和each在句中作主语时，谓语动词用单数形式。
