中小学教育资源及组卷应用平台 2024-2025学年七年级英语下册单元速记巧练(人教版2024) Unit3Keep Fit 速记巧练语法 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” 物主代词 物主代词表示所有关系的代词,是人称代词的属格形式。 (1)分类 分为形容词性物主代词和名词性物主代词。 形容词性物主代词: my我的;your你的;his他的; her她的; its它的; our我们的; your你们的; their他们的 名词性物主代词: mine我的; yours你的; his 他的; hers 她的; its它的; ours 我们的; yours 你们的; theirs 他们的 (2)用法:形容词性物主代词具有形容词的特性,在句中作定语,后面接名词。 名词性物主代词具有名词的特性,后面不可再接名词,在句中作主语、表语或宾语。 Eg: (1) This is my book. = This book is mine. 这是我的书。 --Is this pencil yours or hers -- It’s mine. Hers (= her pencil) is in her bag. -- 这支铅笔是你的还是她的? -- 是我的。她的在她的包里。 名词性物主代词主语时,谓语动词的数随所指代的人或物的数而定。 Eg: -- Whose books are these -- They are his.
