Language practice
Grup wrk: read the sentences and summarize the use f the present perfect tense ,the present simple and past simple.
到目前为止，我们己经学过用多种时态来表达行为或状态。本模块重点复习一般现在时、一般过去时和现在完成时。那么，如何区分这三种时态呢？下面我们以一种行为或状 态为例，来看一下它们有什么不同。请看下面的句子：I ften watch cartn films.我经常看卡通片。I watched Spiderman last week.我上周看了《蜘蛛侠》。I have already watched Spiderman. I d nt want t watch it again.我已经看过《蜘蛛侠》了，不想再看了。
可以看出，(1)表示经常性、习惯性的动作，所以用一般现在时；(2)表示在过去某个时间发生的行为，用一般过去时；(3)中发生的动作也是在过去，但是没有明确的表 示过去的时间，并且本句强调的是结果，即“现在不想再看了”，所以用的是现在完成时。
1.表示经常或反复发生的动作，常与 always, ften, usually, smetimes，nce a day, every day等频度时间状语连用。如：He ften ges t schl by bus. 他经常坐公交车上学。
2. 表示现在的状态、特征、能力和感觉。这类动词有be, lve，like，hate, want, hpe, need, prefer, wish, knw, lk, sund, taste, have 等。如：He is very happy.他很幸福。（表示状态）She lks like her father. 她看上去像她爸爸。（表示特征）
3. 表示客观真理、科学事实和客观存在。如：The sun rises in the east.太阳从东方升起。
4.表示天气、时间、旅程、籍贯等情况。如：—What's the weather like tday?今天天气如何？— It's windy.今天有风。
1. 表示过去某一时间发生的动作或存在的状态，常与表示过去的时间状语连用，如 yesterday, last year/mnth/week, in 2004, three hurs ag, tw years ag 等。如：The children enjyed themselves yesterday.孩子们咋天玩得很高兴。
2. 表示过去经常或反复发生的动作，也可以用used t d表示，常和ften, always等 表示频度的时间状语连用。如：Tm ften went t wrk by bus last year.去年汤姆常常坐公交车去上班。My father used t smke.我父亲过去常常抽烟。
3. 有时动作发生的时间不是很清楚，但确实是过去发生的，应当用一般过去时。如：Wh brke the teapt?谁打碎了茶壶？
1.强调过去的动作对现在的影响，往往具有因果关系，到现在为止已经完成了，常already, yet, just,等副词 连用。如：She has already bught a cmputer.她已经买了 电脑。He has nt fund a jb yet.他还没有找到工作。
2.表示过去某一动作一直持续至今，常与fr, since等引导的时间状语连用。如：I have been in Beijing fr five years.我已经在北待了 5 年了。He has lived here since he mved here.从他搬到这儿以来就一直住在这里。
3.表示经历或经验，常与ever, never, nce，twice, befre等副词连用。如：—Have yu ever been t Shanghai? 你去过上海吗？—I have been there twice.我去过那里两次了。
1. have (has) been t 与 have (has) gne t 的区别have (has) been t表示“去过，到过”某个地方，但现在人已不在那里，常与ever, never, ften, nce, twice 等连用：have (has) gne t 意思是“去了”，人可能在途中或已经在那里。如：Have yu ever been t Shanghai?你去过上海吗？（人不在上海）He has gne t Shanghai.他已经去上海了。（人在上海或在去上海的途中）
（1）现在完成时可以表示某一行为或某一状态从过去某一时间一直持续到现在。这类句子通常包含由fr或since引导的时间状语，fr后接段时间，since后接时间点。如：I have lived in Beijing fr 10 years. 我在北京住了10年了。I have been in this schl since 2000. 从2000年起我就一直在这所学校。
（2）用hw lng对现在完成时的时间状语提问。Hw lng have yu played ftball?Hw lng have yu been like this?
表示某一行为或状态持续多长时间时，根据时间的不同，可以使用不同的时态。I stayed in the htel fr a week last summer.I have stayed in the htel fr a week nw.I will stay in the htel fr a week next mnth.
（3）二者可以转换 fr + 一段时间 = since + 一段时间 + ag He has been here fr five weeks.= He has been here since five weeks ag. 他到这儿已经有五个星期了。
since能引导时间状语从句(主句用现在完成时，从句用一般过去时)，而fr则不能。He has taught here since he came t China. 自从他来到中国就在这儿教书。
（5）现在完成时常用句型：①It is (has been) +时间段+ since +时间状语或从句It is fur days since last Friday. 从上周五到现在已经四天了。It has been tw years since Jim came t Beijing.吉姆来北京已经两年了。
②This is the first (secnd…) time that + 从句，句型中的that从句通常使用现在完成时。This is the first time that Jenny and Danny have been t China.这是珍妮和丹妮第一次来屮国。
当句子的时间状语是“fr + 一段时间”或使用hw lng对肯定句提问时，不能使用短暂性动词，因为短暂性动词不能持续，也就不能和表示一段时间的状语连用。遇到短暂性动词要把它变成相应的延续性动词。如： Tm brrwed the bk a week ag. — Tm has kept the bk fr a week.
注意，在现在完成时的句子中，点动词（终止性动词）一般不能与表示延续的时间状语连用。试比较：汤姆已经来了两小时了。(×)Tm has cme fr tw hurs. (√)Tm has been here fr tw hurs.
终止性动词可以和延续性动词进行转换。(1) 转化为“be+形容词/副词等”。 die → be dead leave → be away (frm) pen/clse → be pen/clsed stp → be ver arrive in (at)/reach/get t → be in/at jin → be a member f/ be in start/begin → be n(2) 转化为意思相同的延续性动词。 brrw → keep buy → have becme/cme→be get t knw→knw
常见非延续性动词和延续性动词的转换
leave — be away brrw — keepbuy — have begin/start — be ndie — be dead finish --- be verpen sth — keep sth pen fall ill — be ill
get up—be up, cme here — be here,jin — be n +组织机构 /be a member f + 组织机构,g there — be there, becme — be, cme back—be back, fall asleep — be asleep,
get t/ arrive/reach — be (in), leave — be away frm, get t knw — knw, g (get) ut —tie ut， put n—wear, catch a cld —have a cld, get married—be married 等。
1. 现在完成时和一般过去时都表示在过去完成的动作。但现在完成时强调的这 一动作与现在的关系。如对现在产生的结果或影响等，而一般过去时只表示动作在过去某一时刻发生，不表示和现在的关系。试比较： a. I have lst my new bk.   我把新书丢了。（现在还未找到）  b. I lst my new bk yesterday.  我昨天把新书丢了。（昨天丢的，现在找到与否没说明。）
现在完成时与一般过去时的区别
2.两种时态的区分  (1)一般过去时的谓语动词用过去式，而现在完成时的谓语基本构成是“助动词 have /has +过去分词”。 (2) 时间状语不同。一般过去时则常与yesterday, just nw, in 2002,“段时间+ag”, “last+段时间”等表示过去时间的状语连用；而现在完成时则常与just, already, yet,  ever, never, befre等副词以及和these days, this week, “fr+段时间”,“since+过去时间/从句”或“since+过去时间+ag”等时间状语连用。
