5、 , etc.) , sometimes , seldom , usually等等，以表示句中的动作或状态是习惯性的、经常性的。例如：They raise ducks as a sideline .他们以养鸭为副业。She doesnt often write to her family, only once a month. 她不常给家里写信，仅一月一封而已。I cycle to work every day .我每天骑自行车上班。It seldom rains here .这儿很少下雨。 2）仅为了描述状态、性质、特征、能力等等。这里的目的是为了描述现阶段的动作或状态，其重点不是强调动作发

9、一直没有时间去打。”球打得好是现在已有的技能，故用一般现在时。2. Youre drinking too much.Only at home. No one _ me but you. A.is seeing B. had seen C. sees D. saw 【分析】C。由 only at home 可知“我”只在家里喝得多，除你之外，没有人看见。谈的是现在一般性情况，故用一般现在时。（二）一般过去时1、定义：过去某个时间里发生的动作或状态，常和表示过去的时间状语连用，如yesterday，yesterday morning，yesterday afternoon，last night，i

10、n 1990 ，two days ago等。一般过去时也表示过去经常或反复发生的动作（过去习惯性、经常性的动作、行为），常如often，always等表示频率的时间状语连用；过去主语所具备的能力和性格。2、构成：（基本结构: 主语+动词过去式+其他）1）一般过去时由动词的过去式表示，其规则动词变化方法如下：情况规则例词一般情况加-edPack-packed以辅音字母加y结尾的动词变y为-iedcarry-carried以元音字母加y结尾的动词加-edplay-played以一个辅音字母结尾的重读闭音节动词双写辅音字母加-edplan-planned refer-referred以不发音的e结尾

11、的动词直接加-dlike-liked provide-provided注：首先闭音节指单元音字母后都是辅单字母的音节。重读闭音节就是在单词中这个闭音节需要重读。英语单词的单节是按单词中元音数量和自成音节来计算的。如beautiful-beau-ti-ful是三个音节interesting-in-teres-ting也是三个音节。 只用一个音节的闭音节单词，都需要重读 如fat cat bag等 有两个音节的结尾音节为闭音节的，有可能重读，如begin-AB 也有可能不重读，如open-AB 有三个音节的结尾为闭音节的单词，读成ABC, ABC时，都不是重读闭音节，只有读成ABC时才是重读闭音节

12、。2）常用不规则变化：常用的不规则动词的过去式：do-did read-read write-wrote win-won be-was/were make-madedrink-drank bring-brought go- went buy-bought throw-threw come-came eat-ate have-had get-gotmeet-met put-put注：was用于第一、三人称单数，were用于其他人称。3) 否定和疑问a否定形式was/were+not；在行为动词前加didnt，同时还原行为动词 Were you students? Yes, we were. /

13、No, we werent. Did the house have two rooms? Yes, it did / No, it didnt.b一般疑问句Did+主语+do+其他？Was/Were+sb.+dosth.？ Jane wasnt in this classroom. The house didnt have two rooms.c特殊疑问句：特殊疑问词+was(were)/did+v+主语+表语/宾语? How many rooms did the house have? Which class was Jane in?3、用法1)一般过去时表示在过去某个特定时间发生，也可以表

14、示过去习惯性、经常性的动作。一般过去时不强调动作对现在的影响，只说明过去的事情。例如： I had a word with Julia this morning. 今天早晨，我跟朱丽亚说了几句话。 He smoked many cigarettes a day until he gave up. 他没有戒烟的那阵子，抽烟抽得可凶了。2）带有确定的过去时间状语时，要用过去时。如：yesterday（昨天）、twodaysago（两天前）、lastyear（去年）theotherday（前几天）、onceuponatime（很久以前）、justnow（刚才）、intheolddays（过去的日子里

15、）、beforeliberation（解放前）、WhenIwas8yearsold（当我八岁时）、at+一个时间点例句：Didyouhaveapartytheotherday? 前几天，你们开了晚会了吗？ LeiFengasagoodsoldier.雷锋是个好战士。注意：在谈到已死去的人的情况时，多用过去时。3）表示过去连续发生的动作时，要用过去时。这种情况下，往往没有表示过去的时间状语，而通过上下文来表示。Theboyopenedhiseyesforamoment，lookedatthecaptain，andthendied. 那男孩把眼睛张开了一会儿，看看船长，然后就去世了。4）表示过去一

16、段时间内经常或反复的动作。常与always，never等连用。 Mrs.Peteralwayscarriedanumbrella.彼得太太过去老是带着一把伞。（只是说明她过去的动作，不表明她现在是否常带着伞。）5）如果强调已经终止的习惯时要用usedtodo（过去常常做，而现在不那样做了）He used to drink alcohol.他过去喝酒。（意味着他现在不喝酒了。喝酒这个动作终止了）I used to take a walk in the morning.我过去是在早晨散步。（意味着现在不在早晨散步了）【习题】1.

20、个月将下很多雨。I think she will pass the exam. 我想他考试会及格的。3、表示将来时间的几种常见方法英语中除了“will /shall+动词原形”表示半来时态外，还可以有以下多种方法：1) 用“be going to+动词原形”表示。主要表示打算和预测：We are not going to stay there long. 我们不准备在那里多待。(表打算)Im afraid theyre going to lose the game. 恐怕他们会赛输。(表预测)Look, its going to rain. 瞧，要下雨了。(表预见) 注：be going to

He was hoping to go abroad but his parents _ that they wont support him unless he can borrow money from the bank. A. were decidingB. have decidedC. decidedD. will decide分析：B。因宾语从句中的时态是一般将来时，主句中的谓

25、语动词不可能是过去时态，排除选项A和D; 由语境判断，不是“将要决定”，而是“现在已经决定”，所以排除D，而选B。2.How can I apply for an online course?Just fill out this form and we _ what we can do four you. A. seeB. are seeingC. have seenD. will see分析：D。表示将要发生的情况，自然是用一般将来时。3. If their marketing plans succeed, they _ their sales by 20 percent. A. will

26、increaseB. have been increasingC. have increasedD. would be increasing分析：A。由于if条件从句用的是一般现在时，所以其相应的主句宜用一般将来时。（四）现在进行时1、定义现在进行时主要用于表示目前正在进行的动作，有时也可表示现阶段在进行的动作。如：The teacher is giving us an English lesson. 老师正在给我们上英语课。The farmers are getting in their crops. 农民们正在收割庄稼。We are making preparations for the
