现在完成时态可用于表达刚刚做完某事或已经做完某事,常见的标志词有already,yet等。下面我们一起看看这几个词的用法:(1)already意为"已经",常放在have/has和动词之间,通常用于肯定句中。如:Theyhavealreadyarrivedatthehospital.

他们已经到达医院了。already也可用于疑问句，表示期望得到肯定的回答或表示惊异，此时常放在句末。(2)yet多用于否定句中,意为"还(没)"；也常用于疑问句中,意为"现在,已经"。如:Thesunhasnotrisenyet.

太阳还没有升起。

B.yet,yet

C.already,yet

D.already,already分析：此题应该选用B项。前面为疑问句，后面是否定回答，故两处空格均应该用yet。B()---HasJim____cleanedhisbedroom?---Yes,hehascleanedit________.A.just,yet

B.already,just

C.just,already

D./,already分析：此题应该选用D项。前面为疑问句，一般不用just/already提问，故A、B、C项都是错误的，后面是肯定结构，故应该用already。D()Jim,haveyouhadyourlunch______?It’sonly10:30inthemorning.A.yet

B.justnow

C.just

D.already分析：此题应该选用D项。前面为疑问句，但是从“It’sonly10:30inthemorning.”中可以看出问话人非常惊讶，故应该用already连接。D动词的过去式的变化和过去分词的变化并不完全相同。我们对它们作了一个大致的分类。(注：例子中单词的变化顺序为：动词原形→动词的过去式

→动词的过去分词)一、过去式和过去分词的变化相同规则变化：一般在动词词尾直接加ed。如：pick→picked→picked;wish→wished→wished;stay→stayed→stayed2.以不发音的e结尾的动词后面加d。如：like→liked→liked;hope→hoped→hoped;phone→phoned→phoned3.以“辅音字母+y”结尾的动词，变y为i，再加-ed。如：study→studied→studied;hurry→hurried→hurried;reply→replied→replied4.词尾只有一个辅音字母的重读闭音节动词，要双写辅音字母，再加-ed。如：stop→stopped→stopped;clap→clapped→clapped不规则变化：5.以不变应万变。如：let→let→let;put→put→put;read→read→read6.若中间有双写e，则去掉一个e，单词末尾再加t。如：feel→felt→felt;keep→kept→kept;sleep→slept→slept7.结尾的字母d变t。如：lend→lent→lent;build→built→built;send→sent→sent8.变为以-ought或-aught结尾。如：buy→bought→bought;bring→brought→brought;catch→caught→caught;teach→taught→taught活学活用1.Writetheformsofthepasttenseandpastparticiple:drink____________see____________find____________leave____________tell____________drankdrunksawseenfoundfoundleftlefttoldtold—WhyisMr.Yangstillintheteachers’office?—Maybehe________hisworkyet.A.doesn’tfinishB.hasn’tfinishedC.haven’tfinishedB

现在完成时：表示过去发生或已经完成的某一动作对现在造成的影响或结果，或从过去开始一直延续到现在的动作或保存的状态，强调的是现在的情况，不能和表示过去的时间状语连用（如：in1990，lastSunday等）。

一般过去时：一般过去时只表示过去的动作或状态，和现在不发生关系（即动作或状态在现在已经结束），它可以和表示过去的时间状语连用。现在完成时与一般过去时的区别：Isawthisfilmyesterday.

（强调看的动作发生过了）

Ihaveseenthisfilm.（强调对现在的影响，电影的内容已经知道了）

Whydidyougetupsoearly?（强调起床的动作已发生过了）
