过去式举个例子。he went to Japan yesterday.他昨天去了日本。这表示的是昨天发生的事情,所以用go的过去是went.过去分词是被动句里使用的。一般构成是was/were+动词的过去分词。它也是表示过去的事情,只不过是被动的意思。

英语中有许多此表示“可能”,但归纳起来,无非就三类:1.情态动词may和can.2.形容词likely,possible,probable.3.副词 maybe,perhaps,possibly,probably. 一.情态动词may (might)和can (could)1. can在肯定句中,表示客观的(理论的)可能性,并不涉及具体某事是否会发生,常可以说明人或事物的特征。要表达具体某事实际,发生的可能性时,不可用can,须用could,may,might 。如:(1)A left-luggage office is a place where bags can be left for a short time ,especially at a railway station.[2003全国,28]行李寄存处,尤其是在火车站,使人们可以短期存放行李的地方。(客观可能性)(2)Accidents can happen on such rainy days.这种下雨的天气可能会发生事故.(客观可能性)(3)Peter may come with us tonight ,but he isn’t sure yet.[1993全国,27]彼得今晚可能来我们这儿,但还没确定.(实际可能性)(4)We may go camping next Sunday.下星期我们可能去野营.(实际可能性)2. may not 表示“可能不”,can not/can’t表示“不可能”,can(could)可用于疑问意义。如:(1)---- Is John coming by train ?---- He should ,but he may not .He likes driving his car.[2002全国,25](表示“可能不”)(2)A computer can’t think for itself ;it must be told what to do .[1991全国,15](表示“不可能”)(3)Mr Bush is on time for everything .How can it be that he was late for the opening ceremony ?[2001上海,27]试比较:This can’t be done by him .这不可能是他干的。This may not be done by him .这可能不是他干的。Can this be done by him ?这可能是他干的吗?(此处不可用may,may用于疑问句表示“可以”。但此句可以说:Is this likely to be done by him ?)另外,could ,might并不一定与过去的时间有关,而表示可能性弱于它们相应的现在时形式。如:This could/may/might be done by him .这件事有可能是他干的。(语气依次递减) 二、形容词:likely , possible , probable1.likely是常用词,只“从表面及想来看很有可能”,常用句型: sb./sth be likely to do It is likely that...如:They are likely to become angry with him .他们可能会对他发怒。It is likely that he will come.注意:(1)、 likely表示“有可能成功的”、“有希望的”意思时,不能用另外两词。e.g What is the likeliest time to find him at home?什么时候最可能在家里找到他?(2)、likely在作副词时,前面一定要加very或most.e.g They’ll very likely ask for an increase in the budget.他们很可能要求增加预算。 2.possible指“由于有适当的条件和方法,某事可能发生或做到”,强调“客观上有可能”,但常含有“实际希望很小”的意思。如:I will do everything possible to help you . 我将尽一切可能帮助你.常用句型: It is possible for sb. to do something It is possible that…e.g It is possible for one man to finish this. It’s possible that he will accept the terms.注意:possible不能以人作主语,也不能说make sb. possible,应说make it possible for sb. to do sth.e.g This made it possible for him to go abroad for further studies.3 . probable 语气比possible强,指有根据、合情理、值得相信的事物,带有大概、很可能 的意思。如:The home team , far ahead , is the probeble winner.主队份遥遥领先,很可能成为胜利者。注意: probable也不能以人作主语,也不能用于It is probable for sb. to do sth.句型, 但可用于句型:It is probable that… e.g It is probable that the winner will get a prize.另外,这三个形容词likely , possible , probable 都可用于句型:It is +adj.+to do sth./that-clause. It作形式主语。但只有likely可以用于句型:sb./sth be likely to do sth .如:(1) It is probable that it will rain today.今天很可能会下雨。(第一个it是形式主语,第二个是天气。)(2) She is the mostgirl to win the prize.A.possible B.probable C.likely D.perhaps因为主语是人,所以答案应是C.表示“有希望的”。试比较: ( ╳) It is probable to rain today.(It指天气)( √ ) It is likely to rain today.(It指天气)但可以说:He is impossble to teach. (=It is impossible to teach him.)注意:不定式动词与主语存在着逻辑上的动宾关系时,句子才正确。三、副词:maybe , perhaps , possibly , probably这四个词都有“可能、或许”的意思,但用法略有不同:maybe和perhaps基本相同,常用于句手,maybe多用于口语。如:Maybe/Perhaps the weather will get better.天气可能会变得好一些。probable是“很可能”的意思,可能性比其它三个大。probably常与will连用,而possibly常与can,could或may连用,may与possibly连用表示的可能性更小,can/could与possibly连用以加强语气。另外,quite possibly表示“很有可能”,very/most probably意为“极有可能”。如:(1) She most/very probably thinks she is right when she says things like that.(极有可能)(2) Eric’s father is a skilled worker and has repaired a lot of this kind ,so he will succeed in repairing this bike.A.probably B.maybe C.may be D.perhaps (A可以和will连用,因此用probably.)(3)No sooner had she seen the frightening snake than the little girl started to run as fast as shecould .A. perhaps B.maybe C.possibly D.probably(和could连用 ,因此用possibly 选择 C )

Reading vocabulary[edit] 阅读词汇A literate person's vocabulary is all the words he or she can recognize when reading. This is generally the largest type of vocabulary simply because a reader tends to be exposed to more words by reading than by listening.Listening vocabulary[edit]听力词汇A person's listening vocabulary is all the words he or she can recognize when listening to speech. People may still understand words they were not exposed to before using cues such as tone, gestures, the topic of discussion and the social context of the conversation.Speaking vocabulary[edit] 表达词汇A person's speaking vocabulary is all the words he or she uses in speech. It is likely to be a subset of the listening vocabulary. Due to the spontaneous nature of speech, words are often misused. This misuse – though slight and unintentional – may be compensated by facial expressions, tone of voice.Writing vocabulary[edit] 写作词汇Words are used in various forms of writing from formal essays to Twitter feeds. Many written words do not commonly appear in speech. Writers generally use a limited set of words when communicating: for example

2、用法不同。
possible和probable可用物或it做主语,一般不用人来做主语,而likely可以用人或物或it来做主语。
3、词性不同
likely既是形容词又是副词,而possible和probable只能是形容词,副词分别为,possibly和probably。

likely强调表面上看来有可能,与probable意思接近,有时可以互换,但likely常暗示从表面迹象来判断;probable则经过权衡正反两方面的理由后而相信某事是真实的或大概会发生。
possible表示客观上潜在的可能性,也许实际发生的可能性并不大。possible一般不用表示人的词作主语,但若真的要用表示人的词作主语,possible后接不定式,这个不定式动作的逻辑宾语应是句子的主语,但此时的possible已经转意为“容易的”。
常指有较大的可能性,表示客观上潜在的可能性,较有根据和充分理由而值得相信的事,意味着经过权衡正反两方面的理由后而相信的事大概会发生的,常译作“很可能”。

客观上可能性大小的比较:依次为probable, likely,possible;may 带有某人主观可能意愿的色彩。possible表示客观上潜在的可能性,也许实际发生的可能性并不大。probable表示有几分根据的推测,比possible表示的可能性大。换句话说,probable的“有可能”,是指有实际的依据或逻辑上合乎情理。likely强调表面上看来有可能,与probable意思接近,有时可以互换,但likely常暗示从表面迹象来判断;probable则经过权衡正反两方面的理由后而相信某事是真实的或大概会发生①It is possible that it will rain, but with such a blue sky it doesn’t seem probable.下雨的可能是有的,但天空一片蔚蓝,可能性似乎不大。②His success is not impossible but hardly probable.他的成功并非是不可能的,但是希望极小。③It is possible but not probable that it will rain.句中possible和probable的位置能否调换,为什么?如果调换意思会发生什么变化?[解答]:possible表示客观上潜在的可能性,但常带有可能性很小的暗示;probable是有几分根据的推测,语气比possible强;句意为可能下雨,但不见得会下。如果二者互换,不合逻辑。④It’s possible but not likely/probable that he’ll come here next month.他下月有可能来这里,但是不是很肯定。⑤It’s probable, not only possible.这事多半如此,不只是可能。⑥Such accidents are not only possible but also probable.这类意外不但可能,而目还会发生。从此句可看出,possible的词义比probable弱。只表示有此可能,而probable则表示可能性很大或很可能会发生。
