home,?,I,often,watch,TV.,同学们，现在我们利用动画情景来理解一般现在时和一般过去时，请看对话。,下面我们一一分解各种时态,What,do,you,often do,at home,?,I,often,watch,TV.,1.,现在请同学们找出每个句子的时态的标志，它是什么？,What,do,you,often do,at home,?,I,often,watch,TV.,2.,现在我们在这两个句子里找到一般现在时的构成。,请看下面两幅图,小明问他的好友,Tom,昨天做了啥,你们知道他做什么了吗？,What,did,you,do,yesterday?,I,played,with my brother,then I,cleaned,my room.,She,visited,the,USA,.,She,went,to,New,York,City.,Where,did,she,go,on vacation?,often,sometimes,every day/month/Monday/,.,in the evening,on Sunday.,动词原形,/,第三人称单数,yesterday,yesterday,morning/afternoon.,Last week/.,in 2011.,动词的过去式,(-ed),刚才我们的动画呈现了两种时态，请看看它们的标志和构成：,真题演练,-,一般现在时与一般过去时的对比,1.Lucy usually_ to school.,(1,2,2,6,),A,walks,B,is walk,C,is walking,D,has walked,2.-Wheres your father?,-Im not sure.He _ to Xian yesterday.(11,33),A.goes B.went C.was go D.has gone,A,剖析：这是陕西省中考题，我们一看题干中有“,yesterday”,，就知道是一般过去时的标志，再分析这个对话的场景，的确是用一般过去时！根据一般过去时的构成，故选,B,。,B,剖析：这是201,2,年安徽省中考题，看四个选项，就知道考查时态，根据句子里的标志,usually,我们就确定选一般现在时：用动词第三人称单数，所以答案是,A,。,What are you doing now?,Im watching TV.,现在我们利用情景来理解,现在进行时,：,What are you doing now?,Im watching TV.,现在我们找出每个句子的标志，谁能找出来吗？,What are you doing now?,Im watching TV.,现在我们在句子里找出现在进行时！,现在我们正在上课，而昨天的这个时候,Jerry,在做什么？,Look at a picture.,Jerry,was swimming,this time yesterday,.,过去进行时,昨天这个时候，也就是下午2:,30,那些人在滇池里做什么？,The people,were cleaning,Dianchi Lake at,2:,30,yesterday afternoon,.,再看下图,昨天这个时候，也就是下午2:,30,那些大妈在广场做什么？,The,old women,were dancing,on the square,at,2:30,yesterday afternoon,.,通过刚才的图片和场景，同学们应该清楚了“现在进行时”和“过去进行时”，请看这两种时态的标志和构成。,时态,标志,构成,现在,进行时,过去进行时,at this time yesterday,at that time,at ten oclock last Sunday.或when引导的从句(when I came in.),was,+-ing,were,Look!Listen!Be quiet!,Its+,时刻,.now,上下文,.,am,is +-ing,are,真题演练,-,现在进行时与过去进行时的对比,3.Be quiet!We _ a soccer game on TV.(11,29),A.watch B.watched C.are watching D.were watching,4.Lucy _ when I came in.,(10,28),A sleeps B was sleep,C was sleeping D is sleeping,c,剖析：,这是,2011,年河北省中考题，从四个选项就能看出是考查时态的，根据句子里的标志,Be quiet!,（此时此刻我们正在看电视上的足球比赛。）就能确定用现在进行时，而根据现在进行时的构成，答案选,C,。,剖析：这是2010年云南省中考题，看四个选项，就知道考查时态的，根据句子里的标志when I came in,(当我进来的那个瞬间），Lucy 在睡觉。我们就应该选过去进行时，而根据过去进行时的构成，所以答案是C。,c,Lets look at a picture!,乌龟说什么？,一般将来时,Lets look at another picture!,蜗牛要为乌龟买什么？,以上两图在它们所说的句子里都用了一个共同的时态，是什么？,是一般将来时，请说出它的标志和构成,:,时态,标志,构成,一般,将来时,tomorrow,tomorrow,afternoon/evening.,next,week/month,in,+,一段时间,will+,动词原,wi,形,be going to+,动词原形,真题演练,-,will,与,be going to,对比,5.People_ robots in 100 years.,(1,3,2,8,),A,will have,B,have,C,are having,D,have had,剖析：这是201,3,年湖北省中考题，看四个选项，就知道考查时态，根据句子里的标志,in 100 years,就选一般将来时，而根据它的构成：,will+,动词原形，所以答案是,A,。,6.-What do you want to do tomorrow,？,-I_ time with my grandma.(11,32),A.spend B.am going to spend,C.spent D.spent,A,剖析：这是山东省中考题，我们根据题干中有,“tomorrow”,，就知道是一般将来时的标志，再看看上下文，的确是要用一般将来时，根据构成，故选,B,。,B,你已经收拾了自己的房间吗？,Yes,I have,already,cleaned,it.,Have,you,cleaned,your bedroom,yet,?,是啊，我已经打扫干净了。,请看下图它是什么样的时态：,林书豪已经在美国生活了多长时间了？,how long has Jemery Lin lived in America,？,He has lived in America,since,he was born.,He has lived in America,for,27,years old.,他从出生就在美国住。,他在美国住了27年了。,如何判断现在完成时,1.,找标志词,2.,联系上下文语境，看过去发生的事情是否对现在,造成影响,already,yet,just,before,so far,since+,时间点,for+,时间段,知道了要用现在完成时，那现在完成时该怎么写，那就要知道它的构成。请记住它的构成：,have/has+过去分词（-ed）,7.,How clean the bedroom is！(09,28),Yes,I am sure that someone _ it.,A cleans B cleaned,C has cleaned D had cleaned,让我们看一道江苏省09年的中考题,C,剖析：,首先看四个选项，都是动词clean的四个时态，由第一句我们得知这个卧室很干净，而第二句猜测是有人打扫了。根据上下文语境，说明“过去打扫的动作”对现在产生了影响“卧室干净”。所以用现在完成时，根据现在完成时的构成，故答案是C,真题演练,8.-,Hasnt Betty come yet?(08,28),-,No,and I_ for her for,more than,2 hours.,A wait B waited,C have waited,D had waited,c,剖析：这是08年云南省中考题，看四个选项，就知道考查时态的，根据上下文语境、特别是答句里的标志for nearly 2 hours,我们就应该选现在完成时，根据现在完成时的构成，所以答案是C。,同学们，今天我们复习了六种时态，“如何利用三部曲将时态进行到底!”是我们这节课的主旨。让我们最后用半分钟扫描一下这些时态的标志和构成吧！,时态,标志,构成,一般现在时,usually,often,sometimes,every day,every year,in the morning,on
