Unit 3

语法点 1 :频率副词

频率副词用来表示动作频率的,一般说来可按频率大小排列:

always (一直)> usually (通常)> often (经常)> sometimes (有时)> hardly ever (很少)> never (决

不)

一、频率副词的位置

频度副词通常 放在动词前面 ,若句子里有情态动词、助动词或系动词

be

,则放在这类动词(第一个)的后面

例如:

It ’s always interesting to watch other people show their talents.

Why do people usually make resolutions?

When we watch movies about the future, we sometimes see robots.

They hardly ever watch TV.

Fewer people will do such jobs in the future because they are boring, but robots will never get bored.

二、用法

1 often, always, usually 等通常和一般现在时连用,表示现在经常或反复发生的动作。

如: It often rains here in April. 这儿四月份常下雨。

2 、对这些频度副词提问时,用 how often

如: ---How often do you write to your brother? --- Three times a month .

--- 你多久给你哥哥写信一次? --- 每月三次。

【注意】

次数”的表达方法:

1 、一次 once ,两次 twice ,三次或三次以上用基数词加上 times three times (三次), five times (五次),

one hundred times (一百次)

2 、表示 “……几次” 的表达方法是:

once a day/a week/a month/ a year (一天 / 一周 / 一年一次)

twice a day/a week/a month/a year (一天 / 一周 / 一月两次)

time 表示不可数名词,意为 “时间”;表示可数名词,意为“次数,倍数”

语法点 2 :物主代词

物主代词是表示所有关系的代词,分为形容词性物主代词和名词性物主代词两种。

形容词性物主代词相当于形容词,置于名词之前作定语。如 my name, your birthday, their parents.

名词性物主代词相当于名词,不能用于名词前。例如: The blue pen is mine.

名词性物主代词 = 形容词性物主代词 + n.
