1、课前热身一、概念频率副词是表示动作发生的频率,多与一般现在时连用。频率副词是一般现在时的“标志词”,它们是表示频率的副词。这些词表示经常性动作或情况,不是某一具体动作,常用于一般现在时。这些频率副词在句子中的位置比较灵活,可以用于句首、句中和句末。在表示动作发生的频率程度上可这样表示:alwaysusuallyoftensometimes never。二 、 频 率 副 词 的 位 置1. 在 be 动 词 之 后 。 如 : She is sometimes very busy. 她 有 时 很 忙 。 2. 在 第 一 个 助 动 词 或 情 态 动 词 之 后 。 如 : I will
2、never forget the first time I met you. 我 将 永 远 忘 不 了 和 你 的第 一 次 见 面 。 3. 在 实 义 动 词 之 前 。 如 : We often go there. 我 们 常 去 那 儿 。 4. sometimes 也 可 放 在 句 首 、 句 中 或 句 末 , often 也 可 放 在 句 末 。 如 : Sometimes she writes to me. 她 有 时 候 给 我 写 信 。 She writes to me often. 她 经 常 给 我 写 信 。 注 : 如 果 有 两 个 助 动 词 , 频 度
3、 副 词 通 常 放 在 第 一 个 助 动 词 后 面 。 We have never been invited to one of their parties. 他 们 聚 会 ,一 次 也没 邀 请 过 我 们 。 She must sometimes have wanted to run away. 她 有 时 候 一 定 想 到 过 要 逃走 。 三、频率副词的用法alwaysalways 意为“总是”,与进行时态连用时,可以表示赞扬,也可以表示讨厌等感情色彩。e.g.(1)I shall always remember my first day at school. 我将永远记住我
4、上学的第一天。(2)He is always smoking. 他总是抽烟。usuallyusually 可以指通常的动作,但是侧重已经形成的习惯,它是从已经形成的角度来说明动作。e.g.(1)I usually do some shopping with my parents on Sundays. 我经常在星期天和我的父母一起去买东西。(2)He usually goes to school by bike. 他通常骑自行车上学。oftenoften 是指经常性的动作,意思为“常常, 经常”。e.g.(1)Children dont often do homework. 孩子们经常不写作业
5、。(2)He is often late for school. 他经常上学迟到。sometimessometimes 意思为“有时,不时”,表示次数较少(低于 often 所表达的次数),常常与一般现在时或一般过去时连用。e.g.(1)Sometimes he goes to work by bike, and sometimes he goes by bus.有时候他骑自行车上班,有时候他乘公共汽车上班。(2)Sometimes I helped my parents in the house. 有时候我帮助父母做家务。hardly hardly 意思为“难得, 几乎从来不”,它所表示的次
6、数非常少。e.g.(1)He hardly drinks. 他几乎不喝酒。(2)She hardly plays cards. 她几乎不打牌。nevernever 意思为“决不, 从未”,表示一次也没有。e.g.(1)He never lives there. 他从来都没有在那儿住过。(2)She never has anything to do. 她一向无所事事。模糊频率副词以下些词都是表示事情发生频率的副词,也是不准确地说某事在一段间内发生的次数。always 总是 usually 通常 often 经常sometimes 有时 hardly ever 几乎 never 从来不例如:On
7、weekends I always surf the Internet.I usually watch TV.I often sleep late.I sometimes listen to music. I hardly ever play computer games. I never play soccer.我们按照频率发生的高低,可以将这几个词排列为always usually often sometimes hardly ever never。请看下面的图解:always usually often sometimes never100% 7080% 60-70% 30-40% 0精
8、确的频率副词以下这些频率副词可以准确地表达事情发生的频率。一次 once 两次 twice 三次 three times四次 four times 五次 five times 六次 six times注意:在记忆时,我们只要记住 once(一次)和 twice(二次)就可以了。其他发生次数只要用“数字times”来表达就可以了。例如:I drink milk and eat vegetables every day.我每天喝牛奶,吃疏菜。I exercise once a week.我每周锻炼一次。I eat McDonalds twice a month.我一个月吃两次麦当劳。I visit
9、 my grandmother four times a year.我一年去看奶奶四次。其他的表达法:every day 每天 once a week 一周一次 twice a month 一 个月两次four times a year 一年四次once two weeks 两周一次twice three months 三个月两次巩固知识频率副词表示与次数,频率有关的副词。我们所学习的频率副词有:( )_、 ( )_ _、 ( )_ _、 ( )_、 ( )_。另外表示次数的有( )_、 ( )_。频率副词的使用: It is usually hot in summer. 夏天通常很热。 总结
10、:频率副词放在_的后面。 My father usually goes to work by bus. 我爸爸总是坐公共汽车去上班。总结:频率副词放在_的前面。Tony doesnt often eat vegetable.他不经常吃青菜。总结:频率副词放在_和_之间。频率副词位置记忆口诀:be 后,动前,助动间 。趁热打铁练一练:一、请把括号中的频率副词放到句中适当的位置。1. She is a good student.(always)_2. My mother is late for school.(never)_3. We play in the playgound.(often)_
11、4. Mike goes to the park.(sometimes)_5.
