据专家权威分析,试题“用所给单词的适当形式填空。1. Has she ever s________ (see) s..”主要考查你对 现在完成时,名词,副词,实义动词 等考点的理解。关于这些考点的“档案”如下:
现在完成时名词副词实义动词
考点名称:现在完成时
现在完成时: 过去发生并且已经完成的动作对现在造成影响或后果,过去某一时间开始并一直持续到现在的动作或状态。 基本结构:主语+have/has+动词的过去分词 句式: 1. 否定句式:现在完成时的否定句式是“haven't (hasn't)+过去分词...”。 如:I have not seen the movie yet. 我还没看这部电影。 2. 一般疑问句:Have(Has)+主语+过去分词...? 如: —Have you finished the work?你已经做完这项工作了吗? —Yes, I have. 是的,我已经做完了。(No, I haven't. 不,我还没有做完。) 3. 特殊疑问句:特殊疑问词+have(has)+主语+过去分词...?如: How many times have you been to the Great Wall?你去过长城几次? 提示:肯定句中有some, already时,改为否定句或疑问句时通常要分别改为any, yet。如: I have already finished my homework. 我已经完成了我的作业。 → I haven't finished my homework yet. (否定句) → Have you finished your homework yet? (一般疑问句) 现在完成时常见两种句型: ①for短语 ②It is+一段时间+ since从句
现在完成时特点: 1. 非持续性动词的完成时的肯定式不能与时间段连用,若要用时间段状语,则应换成相应的持续性动词或状态动词。 例如: He has left. He has been away for an hour. 2. have/has been to 表示曾经去过某地,但现在不在那;have/has gone to表示现在已去某地,现在不在这。 例如: He has been to Canada, but now he is working in our company. Mr. Li in not at home. He has gone to Shanghai. 3. 完成时的肯定式常用already,而否定式和疑问式常用yet,但若already用于疑问句时,表示一种出乎意外的惊讶。 例如:Have you read it already?
现在完成时和一般过去时区别: 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是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。 比较: I have lost my new book. 我把新书丢了。(现在还未找到) I lost my new book yesterday. 我昨天把新书丢了。(昨天丢的,现在找到与否没说明)
have been(to)与have gone( to)的区别: have been(to)表示“去过某地(现在已经回来了)”,可用于各人称; have gone(to)表示“去某地了(说话时某人不在当地)”,常用于第三人称, 前者可与once ,never,several times等连用,后者则不能。 如: They have been to Beijing twice.他们去过北京两次。 He has gone to Beijing . 他去北京了。 现在完成时注意事项: 1.如单纯表示一段时间,或强调一段时间,虽有since一词,也不必用完成时。如: It is two years since his father died. =His father has been dead for two years.他父亲去世已有三年了。
2.终止性动词现在完成时的否定式,已变成一种可以延续的状态,因此可以和表示一段时间的状语连用。如: I haven't left here since 1997.自从1997年以来,我一直没有离开过这儿。
现在完成时的用法: 1.表示动作发生在过去某个不确定的时间,但对现在留下了某种影响和结果。常被just、already、yet 等副词修饰。如: -Have you had lunch yet? -Yes,I have. I've just had it. 2.表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止,可能仍然在进行。 常带有for和since等表示一段时间的状语。如: He has taught here since 1981 他自1981年就在这儿教书。(可能还要继续教) I have't seen her for four years. 我有四年没见到她了。 3.表示说话前发生过一次或多次的动作,现在成为一种经验,一般译为汉语“过”。 常与twice,ever,never,three times等时间状语。 如: I have been to Beijing twice.我去过北京
4. 现在完成时还往往可以同包括现在时间在内的时间状语连用,如: now,up to these few days/weeks/months/years,this morning/week/month/year,just,today,up to present,so far等: Peter has written six papers so far. Man has now learned to release energy from the nucleus of the atom. There has been too much rain in San Francisco this year. The friendly relations and cooperation between our two countries have been enhanced in the past few years. Up to the present everything has been successful.
5.现在完成时往往同表示不确定的过去时间状语连用,如: already(肯定),yet(否定,疑问),just,before,recently,still,lately,never等: He has already obtained a scholarship. I haven't seen much of him recently (lately). We have seen that film before. Have they found the missing child yet?
6.现在完成时的"完成用法" 现在完成时的"完成用法"指的是动作发生在过去某一时刻并已结束,但该动作对现在产生了影响,与现在情况具有因果关系。 例如: He has turned off the light.他已把灯关了。(动作结束于过去,但说明的是现在的情况--灯现在不亮了。) 现在完成时"完成用法"的特点是动作不延续,因此: 该时态只能与表示不定的过去时间状语(如:already,yet,before,recently等)、频度时间状语(如:never,ever,once等)、包括现在时刻在内的时间状语(如:this morning / month /year...,today等)连用。 例如:Have you found your pen yet?你已找到你的钢笔了吗? 7.现在完成时的"未完成用法" 现在完成时的"未完成用法"指的是动作开始于过去某一时刻,一直延续到现在,或可能还要继续下去。 例如: He has lived here since 1978.自从1978年以来,他一直住在这儿。 (动作起始于1978年,一直住到现在,可能还要继续住下去。) I have been in the army for more than 5 years.我在部队已经呆了五年多了。 (动作开始于5年前,一直延续至今,有可能还要继续下去。) 此种用法的句中常需一个表示一段时间的状语(由since或for引导),或表示与现在时刻相连的时间状语(如:up to now,so far)等。 例如: I have heard nothing from him up to now.到目前为止我没有他的任何消息。 注意:现在完成时的未完成用法只适用于延续性动词,不可用于终止性动词,即瞬间完成或延续时间很短的动词。 如:come,go,arrive,leave,join,become,die等。 8.一段时间+has passed+since从句 主语+have / has been+since短语 例如:He has been in the League for three years. 或It is three years since he joined the League. 他入团已三年了 9. 现在完成时常和短语 "up to now /till now","so far" (意思是从过去某一确定的时间一直延续到现在)连用。 Up to/till now he's read many story books. 至今他已读过好多故事书。 I've been to New York three times so far. 至今我已到纽约去过三次。 has gone (to),has been (to),has been (in) 的区别 has gone to:去了没回 has been to :去过 has been in:呆了很久
二.容易混淆的名词 1.work/job ① work是不可数名词,有体力或脑力劳动的意思,又有作为职业概念的“工作”的意思。 ② job作为“工作”解,其实有两层含义:一个是“干活”的“活”或“零工”;一个作为职业的“事”,是可数名词。 job意思是a piece of work,指已做或要做、应做的具体的某种工作,实际含义是“职业”, 而work通常指抽象意义上的工作,是不可数名词,也可指“工作场所”。如: I’m busy today, for I have a lot of work to do.
2. wish / hope ① wish之后可以跟含有动词不定式的复合宾语(wish sb. to do sth.),而hope不可以这样用。例如: I wish you to be happy.我希望你快乐。 ② hope和wish都可以跟从句。hope之后的从句的谓语动词用一般将来时或一般现在时,所表达的愿望可以实现; wish之后的从句的谓语动词用虚拟语气(以后学),表达的愿望无法实现。例如: I hope you like the flowers.我希望你喜欢这些花。 I wish I were a bird.我希望我是一只小鸟。(虚拟语气) ③hope和wish都可以跟动词不定式(hope/wish to do sth.)。wish比较正式,口气比较强烈; 而用hope所表达的愿望容易实现。例如: I hope (wish) to go to college.我希望上大学。 ④wish可接双宾语表示“祝愿、祝福”等,但hope却没有这种用法。例如: I wish you success.我祝愿你成功。
3.silly/stupid/foolish 三个词都含有“蠢”的意思,但略有不同。 stupid所表达的程度最强,指智力、理解力和学习能力差; silly指头脑简单、傻头傻脑,使人觉得可笑,带有一定的感情色彩; foolish是普通用语,尤其是在口语中广泛使用。如: He is stupid in learning math. 他学数学很笨。 Stop asking such silly questions. 别再问这样傻的问题了。 You are foolish to throw away such a good chance. 你真蠢,丢掉这么好的一个机会。<?xml:namespace prefix = "o" ns = "urn:schemas-microsoft-com:office:office" />
4.instead/instead of
instead/instead of
instead是副词,一般放在句首或句末。 而instead of 是介词短语,表示“代替”时, 含有“对比”的意思,其后常跟名词、代词或v-ing形式。如:
Jack didn’t study law. Instead, he decided to become an actor.
杰克没有学法律,而是决定作一名演员。
If you can’t go to the meeting, I can go instead.
如果你不去开会, 我可以(代替你)去。
Could I have tuna instead of ham?
我能否要金枪鱼而不是火腿?
Miss Wang is ill. I’ll teach you instead of her.
王老师病了,我代替她给你们上课。
We walked down the stairs instead of taking the elevator.
我们走着下楼梯而没有乘电梯。
5.frightened/afraid/terrible
frightened/afraid/terrible
① frightened是由过去分词转化的形容词,常指突如其来的震惊,可用very修饰,在句中作定语、表语、宾语补足语。
The old man smiled before he replied to my question.
老人在回答我的问题前笑了笑。
I cannot answer you now. 我现在不能回答你。
How shall I answer? 我该怎样回答?
值得注意的是,answer可引申为“应答”之类的意义,这时不能用reply来代替。如:
answer the door (门铃响了)去开门
answer the telephone 接电话

2.man总称“人”、“人类”,用单数 people泛指“人们”,表示复数概念:People often work in the day. 指“人”的个体,但只表示复数概念:There are five people in my family. 前面加定冠词指“人民”,表示复数概念:Let’s work for the people. 指“民族”时,有单、复数之分:The Chinese people is a hardworking people. person强调“人”的个体,有单、复数之分:There are five persons in my family.

兼作及物动词和不及物动词 英语里有不少实义动词可以兼作及物动词和不及物动词。这样的动词又有两种不同的情况 a)兼作及物动词和不及物动词时,意义不变。试比较: Shall I begin at once?我可以立刻开始吗?(begin作不及物动词) She began working as a librarian after she left school.她毕业后当图书馆管理员。(began作及物动词) When did they leave Chicago?他们是什么时候离开芝加哥的?(leave 作及物动词) They left last week. 他们是上周离开的。(left 作不及物动词) b)兼作及物动词和不及物动词时,有时意义不尽相同。如: Wash your hands before meals.饭前要洗手。 Does this cloth wash well? 这布经得起洗吗?
英汉实意动词用法比较: 与汉语的比较,有时英语动词的及物和不及物的用法,与汉语的用法不一样,请注意下列两种情况: a)有的动词在英语里只能用作不及物动词,而汉语则可用作及物动词,如arrive到达,agree同意,listen听。英语里这些动词后面常接介词。如: We arrived at the railway station at noon. 我们于中午到达火车站。(at不能省去) (比较:We reached the railway station at noon.) Everybody listened to the lecture with great interest. 每个人都很有兴趣地听讲课。(to不可省去) (比较:We all heard the lecture.) Do they agree to the plan?他们同意这个计划吗?(to不可省去)
b)有的动词在英语里能用作及物动词,而在汉语里则不能用作及物动词,如serve为…服务。 Our children are taught to serve the people wholeheartedly. 我们的儿童被教以全心全意为人民服务 用于be动词之后,实义动词之前。
