一、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。名词性物主代词的形式如下：
单数 复数
第一 人称 第二 人称 第三人称 第一 人称 第二 人称 第三
人称
mine 我的 yours 你的 his 他的 hers 她的 its 它的 ours 我们的 yours 你们的 theirs
他/她/ 它们的
1.名词性物主代词在句子中独立使用，相当于“形容词性物主代词＋名词”，其后不能接名词。
There is something wrong with my computer. Could I use yours
我的电脑出问题了。我可以用你的吗？
2.名词性物主代词在句中可作主语、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。
My tennis shoes are right here. His are over there.
我的网球鞋就在这里，他的在那边。
Circle the adverbs of frequency and put them in order from the least to the most often.
Do you often play ping-pong Yes，I play once /twice /three times a week.
How often do you play football I play it twice a week，usually at weekends.
I seldom/hardly ever play it.

二、频度副词
1. 语法概述
频度副词表示某一动作或状态出现的频率，即在一定时间内某一动作或状态重复出现的次数，常用来回答 how often 引导的特殊疑问句。
2. 频度副词的种类
①不表示具体次数的频度副词 (按频率从高到低排列)
always
almost always
usually
often
sometimes
hardly ever (seldom)
never
②表示具体的频率时，通常用once a week (一周一次)、twice a month (一个月两次)、 three times a year (一年三次)等。

Li Ming and his parents go to the park three or four times a month.
李明和他的父母一个月去公园三四次。
3. 频度副词的位置
频度副词一般放在实义动词之前，系动词 be、助动词、情态动词之后。有时为了表示强调，频度副词也可位于句首。
She doesn′t always go to school by bus.
她并不总是乘公共汽车去上学。
I′m always happy to see her. 我见到她总是很开心。
I can never forget it. 我永远不会忘记这件事。

Seldom does he go out for dinner. 他很少出去吃晚饭。
4. 对频度副词的提问
对频度副词进行提问常用 how often，表示“多久一次”。
—How often does he come here？他多久来一次这里？
—Once a week.一周一次。
【特别提醒】how many times 意为“多少次”，对次数进行提问。答语常为“Once./ Twice./基数词 (大于2) ＋times.”
