一、词义辨析不一样1、often英 [??fn] 美 [??:fn]adv.经常；常常；时常；再三2、usually英 [?ju:?u?li] 美 [?ju??u?li]adv.通常，经常，平常，惯常地;一直，向来；动不动
二、词语用法不一样1、often的基本意思是“常常，经常”，主要修饰动词，也可修饰其他副词或形容词，指某件事情在不同场合下屡次发生，具体的时间意味不强。有时often还表示“在许多场合下”。可用于一般时态，也可用于完成体。2、usually是频度副词，意思是“常常”“习惯于”，有遵循常规的意思，其经常性约为90％。usually只能用作状语，位于实义动词之前，系动词、助动词或情态动词之后，也可放在句首或句末表示强调。三、同义词辨析不一样often、usually意思相近，表示的频率不同。如：1、often经常，语气弱于usually，侧重动作发生的次数具有经常性，具体时间意味不强。He often goes to school. often表示的频率是60%。2、usually通常，通例地，指习惯性动作，较often大，偶尔有间隔。He usually goes to school. usually表示的频率是90%。
often与usually的区别：表示的时间程度不同。体现在：1) usually(75%)意为“通常”，着重表示已形成习惯的动作，反义词为unusually.2)often(50%)相当于at times, 意为“时常，经常”。表示常常这样，但不总是这样，反义词为seldom.拓展资料often1、时常；常常many times同义词：frequentlyWe often go there.我们常去那里。I've often wondered what happened to him.我时常纳闷他出了什么事。How often do you go to the theatre?你多长时间看一次戏？I see her quite often.我常常见到她。Try to exercise as often as possible.尽可能经常锻炼。We should meet for lunch more often.我们应该更常一点相聚在一起吃午饭。It is not often that you get such an opportunity.你得到这样的机会，可不是常有的事。2、往往；大多in many cases同义词：commonlyOld houses are often damp.老房子大多都潮湿。People are often afraid of things they don't understand.人往往对自己不懂的东西感到恐惧。All too often the animals die through neglect.动物因缺乏照料而死亡的事司空见惯。usually1、adv通常;惯常If somethingusuallyhappens, it is the thing that most often happens in a particular situation.The best information about hotels usually comes from friends and acquaintances who have been there...关于酒店的最可靠信息通常来自曾经去过那里的朋友和熟人。2、PHRASE比平时更…You usemore than usuallyto show that something shows even more of a particular quality than it normally does.She felt more than usually hungry after her excursion...远足后，她比平时感觉更饿。
usually的频度为70%左右，译为“通常”、“平常”，即很少例外。例如： Where do you usually spend the summer holiday? 你通常在什么地方过暑假？ He usually goes to bed at ten o”clock. 他平常10点钟睡觉。 It”s more than usually crowded today. 今天比平时拥挤。 三. often的频度为50%左右，意为“常常”，不如usually那么频繁，表示动作重复，中间有间断。例如： Mary often weeps when she is alone. 玛丽一个人经常哭泣。 He is often late for school. 他上学经常迟到。 ▲Very often语气比often重，常位于句首或句末。例如： Very often you cannot know one without knowing the other. 如果不知其一，往往不知其二。 He doesn”t go to london very often. 他不常去伦敦。
