另外,once a year (每年一次), twice a week (每周两次), three times a day (一天三次), every Saturday afternoon(每星期六下午)等,
这些时间状语也表示频率,它们可以和频度副词用在同一个句子中,表达上没有重复。如:
We usually go to the cinema four times a month. 我们通常一个月看四次电影。

  • 频度副词的用法:
     频度副词是副词的一种,在初中阶段常用的有四个,即always, usually,often,sometimes。它们的用法如下:
    一、频度副词在句中的位置。
    1.频度副词在句中习惯上位于be动词、助动词之后,行为动词之前。如: 
    She is often late for school.她上学经常迟到。
    He usually goes to bed at about 12.他通常(午夜)十二点钟睡觉。
    When do you usually get up in the morning?早上你通常什么时候起床?
    2.sometimes是个特殊的频度副词,既可以放在be动词、助动词之后,行为动词之前,也可以放在句首,还可以放在句尾。如:
    I sometimes think that it is a great mistake.我有时想这是一个大错。
    Sometimes I help my mother in the house.有时候我帮助妈妈做家务。
    3.often可以放在句中,也可放在句尾,习惯上不放在句首。如: 
    We have been there quite often.我们经常到那儿去。
    She writes to me often. 她经常给我写信。
    4.如果有两个助动词,频度副词通常放在第一个助动词后面。如:

    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。
    5.这些频度副词的位置与句中谓语动词有无助动词有关。句中没有助动词时,副词置于动词be之后,其它动词之前。
    频度副词位于助动词之前两种情况:
    ①为了表示强调,频度副词有时也可位于动词be、助动词、情态动词之前,此时助动词等应重读。如:
    She always was late. 她老是迟到。
    I never can remember. 我永远也记不住。
    ②在简略答语中,当频度副词与动词be、助动词或情态动词位于句末时,频度副词必须前置。
    —“Philip is late again.”
    —“Yes, he always is.”
    —“菲利普又迟到了。”
    —“是的,他总是迟到。”
    — “Can you park your car near the shops?”
    —“Yes. I usually can.”
    — “你可以在商店附近停车吗?”
    —“是的,通常可以。”
    6.频度副词后的动词可以是动词的任何形式,具体什么形式和频度副词本身没有关系。
    如:
    I have never been to the moon.
     He sometimes goes to school by bike.
       
    二、表示频度方面的区别:
    1.always是频度最大的词,意为"总是;永远"。如:
      I shall always remember my first day at school.我将永远记住我上学的第一天。
    2.usually意为"通常",即很少例外,频度仅次于always。如:
      What do you usually have for breakfast?你通常早餐吃什么?
    3.often意为"经常",在频度上不如usually那么频繁。如:
      Li Ping often does his homework in the afternoon.李平经常在下午做作业。
    4.sometimes意为"有时候",频度比often小,表示动作偶尔发生,间断较大。如:
      1.I sometimes go to the library.我有时去图书馆。
      2.Sometimes I read a book in the evening.我有时在晚上看书。

    三、频度副词与not连用时,表示部分否定;对频度副词进行提问时,要用how often。如:
    1.A great scholar is not always a very wise man.大学者未必一定是极聪明的人。
    2.We go to the cinema sometimes.(对划线部分提问)
        How often do you go to the cinema?

    • 一般将来时的构成:
      1. 用will或shall表示   
      “助动词will或shall+动词原形”这一形式,表示将来发生的事情,用于征求对方的意见或表示客气的邀请。在口语中will用于所有人称,书面语中第一人称常用shall,如:   
      ①Tomorrow will be Sunday. 明天就是星期天。    
      ②The rain will stop soon. 雨很快就要停了。    
      ③Shall we go there at five? 我们五点钟去那儿,好吗?   
      ④Will you please open the door? 请你把门打开,好吗?   
      2. 用be going to结构表示    
      “be going to+动词原形”用来表示近期或事先考虑过的将要发生的动作以及已有迹象 表明必将发生某事,意为“打算;就要”。如:    
      ①We’re going to meet outside the school gate. 我们打算在校门口见面。    
      ②Look! It's going to rain. 瞧!快下雨了。   
      3. 用现在进行时表示   
      表示位置转移的动词(如:go, come, leave, start, arrive等),可用现在进行时表示将来时。如:   
      ①Uncle Wang is coming. 王叔叔就要来了。   
      ②They’re leaving for Beijing. 他们即将前往北京。   
      4. 用一般现在时表示   
      根据规定或时间表预计要发生的动作,在时间和条件状语从句中,都可用一般现在时表示将来时。如:   
      ①The new term starts (begins) on August 29th. 新学期八月二十九日开学。    
      ②If it doesn’t rain tomorrow, we will go out for a picnic.
      如果明天不下雨,我们将出去野餐。   
      5. 用“be+动词不定式”或用“be about to +动词原形”的结构表示,如:   
      ①He is to visit Japan next year. 明年他将访问日本。    
      ②They’re about to leave. (=They’re leaving.) 他们就要走了。

    • be going to与will的区别:
      be going to与will两者都可表示将要发生的事、将要去做某事,但它们有如下几点区别:
      1. be going to 表示近期、将要发生的事情,will 表示的将来的时间则较远一些,如:
      He is going to write a letter tonight.
      He will write a book one day.
      2. be going to 表示根据主观判断将来肯定发生的事情,will表示客观上将来势必发生的事情。
      He is seriously ill. He is going to die.
      He will be twenty years old.
      3. be going to 含有“计划,准备”的意思,而 will 则没有这个意思,如:
      She is going to lend us her book.
      He will be here in half an hour.
      4.在有条件从句的主句中,一般不用 be going to, 而多用will, 如:
      If any beasts comes at you, I'll stay with you and help you
