Unit 2 语法篇_学生通过本讲学习，能够掌握本单元的重点语法，并在综合能力上有一定的拓展。频率副词的使用用法 几个频率副词的用法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。（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时间内发生的次数。always 总是usually 通常often 经常sometimes 有时hardly ever 几乎never 从来不例如：On 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： alwaysusuallyoftensometimesnever 100% 7080% 60-70% 30-40% 0精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 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 1.
