I.名詞性物主代詞
物主代詞是表示所有關系的代詞，分為形容詞性物主代詞和名詞性物主代詞兩種。
七年級上冊已介紹了形容詞性物主代詞，本單元介紹名詞性物主代詞。
一、物主代詞的分類：
用法
名詞性物主代詞相當于名詞=形容詞性物主代詞+名詞，不能用于名詞前，說話時要加重語氣。
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.
在句中可作主語、賓語、表語等。作主語時，謂語動詞的單復數形式由名詞性物主代詞所指代的名詞的數來決定。
Your English books are here. His are over there.
My pen is blue, yours is red.
II頻度副詞
頻度副詞是副詞的一種，表示事情發生的頻率，常用來回答how often 引導的特殊疑問句。
常用的不表示具體次數的頻度副詞按頻率從高到低排列:
always>usually >often>sometimes>seldom (hardly ever)>never
頻度副詞通常放在實義動詞前面。如果句子里有情態動詞、助動詞或系動詞be，頻度副詞通常放在這類動詞之后。可記為 be情助后實義前。
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.
表示具體的頻率時，通常用once a week(一周一次)、twice a month (-個月兩次)、three times a year(--年三次)等。
I play basketball twice a week. My family travel three times a year.
對頻度副詞進行提問常用how often,表示多久一次。
A:How often does he play basketball B:Once a week.
對次數進行提問常"用how many times,表示多少次，答語常為"Once./ Twice./基數詞(大于2)+times.
A:How many times do you exercise every month B:Three times.
