I.名词性物主代词
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。
七年级上册已介绍了形容词性物主代词，本单元介绍名词性物主代词。
一、物主代词的分类：
用法
名词性物主代词相当于名词=形容词性物主代词+名词，不能用于名词前，说话时要加重语气。
Eg: A: Is this your pen
B: No, it isn't. The blue pen is mine.
A: There is a ping-pong bat here. Is it yours
B: No, it isn't mine. Is it Ella's
C: No, hers is at home.
在句中可作主语、宾语、表语等。作主语时，谓语动词的单复数形式由名词性物主代词所指代的名词的数来决定。
Your English books are here. His are over there.
My pen is blue, yours is red.
II频度副词
频度副词是副词的一种，表示事情发生的频率，常用来回答how often 引导的特殊疑问句。
常用的不表示具体次数的频度副词按频率从高到低排列:
always>usually >often>sometimes>seldom (hardly ever)>never
频度副词通常放在实义动词前面。如果句子里有情态动词、助动词或系动词be，频度副词通常放在这类动词之后。可记为 be情助后实义前。
例如:
I always play tennis near my house.
We usually practise three times a week after school.
I often go swimming because it keeps me healthy.
Sometimes I have eggs and beans. I seldom/hardly ever see my friend Lucy now. A kind word is never lost.
表示具体的频率时，通常用once a week(一周一次)、twice a month (-个月两次)、three times a year(--年三次)等。
I play basketball twice a week. My family travel three times a year.
对频度副词进行提问常用how often,表示多久一次。
A:How often does he play basketball B:Once a week.
对次数进行提问常"用how many times,表示多少次，答语常为"Once./ Twice./基数词(大于2)+times.
A:How many times do you exercise every month B:Three times.
