1、频度副词always, usually, often, sometimes, seldom,hardly 和 never 是英语中最常见的频度副词,它们在句中的位置大致相同:通常放在行为动词之前,连系动词 be、助动词和情态动词之后。但它们所表示的含义及频度是各不相同的。【知识梳理】always 的频度为 100%,表示动作重复、状态继续,中间没有间断,意思是“总是、永远地、一直” 。例如:Customers are always right. 顾客永远是对的。【友情提醒】1、always 与进行时态连用,并不强调动作正在进行,而是表示说话人的“赞扬、不满、厌烦”等情绪,有强烈的感情色彩。例如
2、:She is always thinking of how she can do more for people. 她总是在考虑怎样为人们多做些事。 (表示赞扬)He was always asking for money. 他总是要钱。 (表示厌烦)She is always asking for leave. 她总是请假。 (表示不满)2、always 与 not 连用,表示部分否定,意思是“不总是” 。例如:The rich are not always happy. 有钱人未必总是幸福的。usually 的频度为 80%左右,意为“通常、平常” ,即很少有例外。例如:He usual
3、ly walks to school if it doesnt rain. 假如不下雨,他通常步行去学校。often 的频度为 60%左右,意为“常常、经常” ,但不如 usually 那么频繁表示动作的重复,中间有间断。例如:He often goes to school without having breakfast. 他经常不吃早饭去上学。sometimes 的频度为 40%左右,意为“有时” ,表示动作偶尔发生,相当于 at times 或from time to time。可以位于句首,表示强调。例如:Sometimes he does it this way and someti
4、mes he does it that way. 他有时这样做,有时那样做。seldom 的 频 度 为 20 %左 右 , 意 为 “很 少 、 不 常 ”, 相 当 于 not often。 如 :The old woman seldom leaves her house because she cant walk far.那 老 太 太 很 少 出 门 , 因 为 他 走 不 远 。hardly 的 频 度 为 10%左 右 , 意 为 “几 乎 不 、 简 直 不 ”, 常 和 ever 连 用 表 示 强 调 。 例 如 :I hardly ever meet my English
5、teacher these days. 这些天我几乎没遇到我的英语老师。never 的频度为 0%,意为“从来不、永不” 。例如:I will never forget your help. 我永远不会忘记你的帮助。【拓展延伸】1、频率副词可放在句首或句末来加强语气,放在句末时,常用 very 或 quite 来修饰。例如:I dont go to the cinema very often. 我不常去看电影。对频率副词的提问常用 how often。如:How often do you go to the supermarket? 你多长时间去一次超市?Every Sunday. 每周日。2
6、、有时为了强调,never 和 seldom 可以放在句首,但这时句子的主语和谓语要互换位置,采用到装语序。如:He seldom does after-school activities after school.Seldom does he do after-school activities after school.放学后他很少做课外活动。Well never have junk food.Never will we have junk food.我们永远不吃垃圾食品。【巧学妙记】频率副词的用法口诀频率副词有七个,句中位置不可轻。若和行为动词遇,置于之前要小心。系动助动和情动,频副置后
