I think it’s Han Lin’s. His has “HL” on it. 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. I never do. 思考： 形容词性物主代词和名词性物主代词的用法是什么？ Is this baseball glove yours? Yes, that’s mine. Thank your. Whose badminton racket is this? I think it’s Han Lin’s. His has “HL” on it. 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. I never do. never< seldom (hardly ever ) < once / twice / three times a week< often <usually   单数 复数 形容词性物主代词 my (我的) our (我们的) your (你的) your (你们的) his / her / its (他 / 她 / 它的) their (他们 / 她们 / 它们的) 名词性物主代词 mine (我的) ours (我们的) yours (你的) yours (你们的) his / hers / its (他 / 她 / 它的) theirs (他们 / 她们 / 它们的) 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。具体见下表： 物主代词 注意： 多数名词性物主代词是在形容词性物主代词后面加-s构成；两组形容词性物主代词和名词性物主代词的形式相同：his 和 its；一组形式完全不同，形容词性物主代词形式为 my，名词性物主代词形式为mine。 形容词性物主代词具有形容词的特性，后面要跟名词；名词性物主代词起名词的作用，相当于“形容词性物主代词+名词”。如： That is my new book. That new book is mine. This isn’t your pen. Yours is yellow. 频度副词 表示动作频繁程度的副词叫做频度副词。常见的频度副词有always, sometimes, seldom (hardly ever), usually, often, never等。 ★常见的频度副词按频率大小排列如下：always (总是) > usually (通常) > often (经常) > sometimes (有时) > seldom (hardly ever)(很少) > never (从不)。 ★频度副词的位置：频度副词通常放在实义动词之前，be动词、助动词或情态动词之后，但有些频度副词如often，sometimes等位置比较灵活，还可以放在句首或句尾。如： My brother usually has an egg for breakfast. Sam is always happy. Mrs. Lee can seldom watch a movie on weekdays. Her dad sometimes goes to work on foot. / Sometimes her dad goes to work on foot. / Her dad goes to work on foot sometimes. ★当对频度副词及表示事件发生频率的短语提问时，常用how often。how often意为“多久一次”。如： I sometimes listen to music in the evening.
