1.beat (n)敲击,跳动 (vt)打,输
beaten track 常规;惯例;被踩出来的路
辨析:beat和win的用法:① beat表示“在战斗中战胜对手,宾语是人,不是物”。
beat后接运动员、球队或对手等。例如:I can beat you at chess .
② beat意为“胜于,击败”。例:He is going to beat the world record .
③ win战胜,因赢,它的宾语是物,如比赛,战争。win后接“a game, a war, a watch, a prize”等。例:The boy won the first prize in contest . I can always beat him at chess.
Which team win the football match? We beat them by score 2 to 1.
辨析: beat; hit; strike的用法:这三个词都有”打;击;敲”的意思,但仔细分辩,还是有其各自的用法。① beat 表示”连续不断地打击”;尤其指心脏的跳动。
● beat sb in the chest ● beat…to death ● to beat a drum敲鼓
② hit表示”撞击”(尤指一次性的)或命中(目标)。而strike除了与hit同义外,还可以理解为划(火柴);给人深刻印象等。 如:The man looked dead but his heart was still beating.这个人看上去已经死了,可心脏还在跳动。
He hit the ball so hard that it went over the wall.他使劲地击球,结果球越过了墙。

※比较:be famous as ; be famous for ;be famous to和 be famous at 的用法:

比较:maybe, probably和 perhaps几个表示“可能”,“也许”,“大概”副词用法的区别:

Maybe he will come, and maybe he won’t. 他也许来,也许不来。
① probably 可放在句首和行为动词之前和助动词、情态动词或系动词be 之后。不可紧接于not等否定词之后;可与maybe替换。强调可能性很大。相当于:most like. e.g:
Probably he might be cured.(治愈) I probably didn’t try hard enough.
It’ll probably rain. Probably he won’t come.
“Can you come here on time?” “Probably”.
He won’t come probably. 不说:He won’t probably come.
③ perhaps 在句中位置的不同,意思也不同。相对probably来说,可能性稍小。反义词 surely .相当于maybe. e.g: Perhaps he will leave for home.(也许)
He will perhaps leave for home.(恐怕) Perhaps it will rain this afternoon.今天下午也许会下雨。(也许不下)
② possibly (形容词 possible )用于肯定句中。常与can , may , must 等情态动词连用,比probably语气弱。用于否定句、疑问句中,意思为“无论如何,不管怎样”。e.g:
I’ll do all I possible can. It may be possible so. He can’t possibly forget it.
Can it possibly rain tonight?
⑤likely 其主语可以是人、物或it ,句型结构:主语+ be likely + 动词不定式”: It is likely that 从句;但不说:It is likely for sb to do sth ; 通常与 most, very 连用(用于口语中)。e.g: The weather is likely to be fine. = It is likely that the weather will be fine.
Most likely she is over thirty. 她也许已经过30 了。
备注:may be 是由“情态动词may + be(动词原形)”结构作谓语。表示“或许”,具有可能性;对现在事情的推测。其后可用形容词、名词、代词及介词短语等作表语。e .g: It may be true.
15. about
比较: 表示“关于”的about 、on 和 of 介词的区别:
⑴ about 表示“关于,有关”。指内容较为普通,不正式,含有随便谈论的意思。涉及的内容广泛。
在搭配上,只有about才适合与dream, talk, speak, know, think, write, quarrel, agree, teach, learn, tell, read, hear, find out 等动词及story. ideas, oppinions等名词连用,这些情况不能用on 搭配。注意:about
(=around)作副词,表示“周围”“附近”。 Is there anybody about?
⑵ on表示“关于”指内容较为严肃或学术性的。可供专门研究问题的人阅读或参考。
⑶ of说及,提及。只表示事情的存在或发生,并不涉及详情。常与动词:dream, talk, speak, know, think, write, quarrel, agree, teach, learn, tell, read, hear, e.g:
I know nothing about the matter. I have never hear of such things.
我对这事一无所知。
He has written a lot of books on the history of Japan. I know of her. Please hear me out.
他写了许多关于日本历史的书。
Have you heard from Mrs Scobie? You’ll hear from you father when he gets home.
I heard of(about) it long ago. How did you hear about(of) our product?
4.辨析:情态动词 must , can和may 表示“推测”的用法:
(情态动词后面直接加动词原形,无人称和数的变化。)
⑴ must 表示“推测”,只能用于肯定句中,意为“很可能”。语气比may 肯定。
常用:“must have + 动词过去分词”,表示“一定已经”。
⑵ can 表示“推测”,可用来代替“must” 推测,意为“可能会”;帮助构成否定。
如:can’t + 动词原形(推断现在);can’t have + 过去分词(推断过去)。意为“不可能”。构成“反意疑问句”中的附加成分需根据must 后的动词选用相应的形式。
⑶ may 表示可能性;意为“可能,也许”。对现在事情的推测用“may + 动词原形”;对已经发生的事情的推测用“may + have +过去分词”。e.g:
That must be Tom. 那一定是汤姆。
They must be wrong, aren’t they? 他们一定错了,是不是?
⑷.小结“情态动词+have +done ”的用法:
① must have done 对过去发生的事情的肯定推测,“一定……” They must have got lost .
② can’t / couldn’t have done对过去发生的事情的否定推测,“一定没有” they can’t have got lost .
③ needn’t have done 过去没有必要做却做了,“本来不必做… He need not have come last night .
④ should/ ought to have done 表示“应该做某事却没有做,本来应该做……”
但 should be doing 表示“应该正在做……”
You shouldn’t have told him about this .
You should have come here five minutes ago .
⑤ shouldn’t / oughtn’t have done 本来不该做却做了。 They shouldn’t have come .
⑥ might / may have done 过去可能做了某事(可能性小)“可能已经…… ”
She isn’t by now ,she may have missed her train .
⑦ could have done 过去本来可能做却未做,“本来可以做 ……”。
My English-Chinese dictionary has disappeared , who could have taken it ?
⑧ would have done 愿意做某事却不能做,“本来想要做…… ”
If I had had a chance , I would have tried .
6. 辨析a few; few 和 a little; little ; a good few ; quite a few 的用法:
⑴ a few; few 修饰或替代可数名词复数形式。既作名词又作形容词,意为“少数”, “几个”。表示虽
少但还有一些,常作定语,后面接可数名词复数形式。a few 表示肯定;few 表示否定。但也可作主语。I have a few English books besides this one.
They will be here in a few days.
A few of the survivors (幸存者)are still living.
He made few friends except Jane.

⑵ a little; little 修饰或替代不可数名词。既作名词又作形容词和副词。意为“一些”, “一点儿”。表示几乎没有,常作定语,后面接不可数名词。a little 表示肯定 ;但not a little 不少许(含双层否定,等于肯定); little 表示否定。但也可作主语、宾语。He was not a little afraid. There is a little milk left in the cup.
I am a little tired. There is little water in the lake.
Little remains to be done about it.
⑶ few; little 含有否定意义。
⑷ a few ; a little 含有肯定意义。
①——Good morning, Mr Brown. Would you please tell me the result of the exam?
—–OK, you did quite well. You’ve made mistakes.
A. few B. a few C. little D. a little
② There issalt on it. A. few B. a few C. little D. a little
⑸ a good few (意思相当于)too many 表示“相当多;很多”。与可数名词复数连用。
e.g: A good few cars parked there.
⑹ quite a few (意思相当于)a good many 表示“相当多;很多”。与可数名词复数连用.
There are quite a few picture-books in our library.
I have been teaching at university a good many years.
⑺ a bit “一点儿”,“一些”;常作状语,修饰动词、形容词。a bit 后可接名词,of用连接。not a bit 表示“不多”(含否定)。注意:a bit 在for之后表示“一会儿;一些时间”。例a bit of water 一点水; know a bit of English 懂点英语; a bit of good advice一点宝贵意见
He was not a bit afraid. The weather is a bit warmer.
He didn’t care a bit. I feel a little bit cold.
7. 辨析:用代替词 So 表达“也是如此”、“确实如此”的句式:
⑴ So + be(助动词、情态动词)+主语。表示“……也是如此”。(肯定句式)表示前面所说的情况也适
合于另一个人或物,此时主语与前句中的主语不一致。主、谓语要用倒装语序,前、后两句中的时态
要一致。如果表示“某人也不”。可用“Neither + 助动词 + 主语”的句型。(表示否定式)
—- I have a younger sister. —– So do I.
—- I am not happy. —— Neither is he.
⑵ So+主语+be(助动词、情态动词)。表示“……的确如此”。表示确认,重复并强调前句所说的
内容。其主语与前句中的主语指同一个人或物。主、谓语序不倒装。
①—-Jim enjoys listening to pop music. —-.
A. So does Helen B. Also is Helen C. Helen likes also D. So Helen does
②—-You’ve left the light on. —- . I’ll go and turn it off.
A. So I have B. So do I C. Nor have I D. Neither I do
③—-It may be in the bag. —-Ah,.
A. So is it B. So it is C. Nor has it D. Neither it is
④—-They eat a lot of potatoes. —-.
A. So we do B. Also do we C. So do we D. We like also
⑶ 用替代词so 还是 not ① 替代词so可以跟在动词:think,hope,believe,tell,do,speak,say,expect,imagine, suppose 等之后。表示“这样,如此”。替代肯定结构的that从句,为了避免重复,变为否定式有两种:第一种可用动词的否定结构,或用not 代替so .第二种替代词not 只能代替否定结构的that 从句。e.g: ① It was his duty to do so. ② Don’t you think so.
③ Do you think it’s going to snow today? —— I believe not.
④ I think not.= I don’t think so.
⑤ I hope so.只能说:I hope not. 而不说:I don’t hope so.
8. 辨析:be good for;be good to; be good at 的用法:
⑴ be good for……接指物的名词。表示“对……有好处”
⑵ be good to ……接指人的名词或代词。表示“对……有好处”
⑶ be good at ……接名词、代词(宾格)或v-ing 形式。意为“擅长”
① Chocolate is good D your health.
A. at B. to C. with D. for
② —- I think drinking milk is good A our health.
—- Yes, I agreeyou.
A. for ; with B. to ; to C. with; to D. at; with
9.辨析:either…or ;neither…nor ;both…and ;not only … but also…的用法:
⑴ either…or… 作并列连词,通常连接并列主语、谓语、宾语、状语或表语。当连接并列主语时,谓语动词必须与or.后面的主语在人称和数上保持一致。意为“不是…就是…;要么…要么…;或者…或者…。”
⑵ neither…nor… (否定式)并列连词,所连接的成分一定要对称或平衡。当连接并列主语时,其谓语动词的形式应与动词邻近的单词的数一致。意为“既不……也不…既非……又非…”
⑶ both…and…关联连词,通常连接两个名词(词组)或与之相当的代词。在其句中充当主语、宾语或表语;连接两个形容词可充当表语,连接两个动词(短语),可充当谓语;其连接的两个词语最好是同性的。意为“不但……而且……;既……又……”。
⑷ not only…but also… ▲连接主语时,谓语动词须和邻近的主语保持一致。▲连接谓语时,not 前
不可有助动词。▲连接其它部分,位于句首时not only 后的主谓需要倒装;but also 后的主谓不能倒
装。意为“不但……而且……” 。▲ also 有时可用too 替换;当连接的是两从句,而且每个从句都
有自己的主语时,also 常可省略。▲但 not …but …(否定前部分,肯定后部分)“不是 …… 而是”。
① Either my father or my mother B dinner on weekdays.
A. cook B. cooks C. is cooking D. cooking
② Either Jane or Steven B watching TV now.
A. were B. is C. are D. was
③ —- Can I come this evening or tomorrow morning?

⑤ —- That place is not interestingat all.(一点也不)
—– A of us wants to go there.
A. Neither B. Both C. All D. Some
⑥ His hobby is D taking photos D collecting stamps. It is growing flowers.
A. either … or B. both … and … C. not only … but also … D. neither … nor ….
⑦ —— Have you sent your parents an-e-mail telling them you arrived safe?
—- No.__C__ of them can use a computer.
A. none B. both C. neither D. All
15.no matter what …+ be like 表示“不管……如何或是怎样的情况”含有让步状语的主从复合句
中,若主句是一般将来时,则从句要用一般现在时来表示将来。但 no matter how (不与like)连用。
16.现在完成时态:“由 have/has + 动词的过去分词” 构成:【注意要点】
⑴ 现在完成时态表示过去发生的动作对现在造成的影响或结果,可用非延续性动词。如果表示过去发生的动作或状态一直延续到现在必须用延续性动词。
⑵ 在完成时态中,必须用延续性谓语动词表示动作的延续。(work是延续性动词);
⑶ 在完成时态中,终止性动词由于表示的动作及其短暂,不能持续,因此不能和表示一段时间的状语连用。但可用: It is +一段时间+since +一般过去时间的句式。表示“自从…以来有…的时间… ”。It’s…since…
结构中的动词时态搭配较为固定,多数情况下主句用一般现在时或现在完成时,从句用一般过去时。
⑷ 现在完成时态可用于包括现在时间在内的时间状语,表示到目前为止,today, this month /year 等。
already 作副词,(常放在行为动词前或系动词后),表示“已经”,常用于完成时态的肯定句中。
但all ready意义为“都准备好了”。
⑸ yet 作副词,(常放在句末),表示“已经”,常用于疑问句和否定句中。
still 作副词,表示“仍然”,用于疑问句和肯定句中。其反义句为“not yet”
ever 作副词,表示“曾经”,指从过去到目前为止的任何时候,相当于at any time;用于一般现在时表示频率。可用于完成时态的肯定,疑问和否定句中。其反义词“never从未”。
⑹ how long (副词)表示某个动作或某种状态持续多久(持续过程没有中断)。提问时
间或距离的长短(时间长至几年,短至几秒),用于现在完成时态中,表示过去发生的动
作或状态持续到现在甚至将来;必须和延续动词连用。答语可用:for/about /since /until/
from…to…表示一段时间的词组连用。如:for /about two weeks. 而since /ever since + 时
间点或一般过去时的句子,表示一段时间。如:Since 2004. 还有during+时间段,是现
在完成时的时间志,表示“在一段时间内”,但during更强调过程。但:“in + 一段过去
时间”只能用于一般过去时。⑦ by then 表示“到那时”; so far “迄今为止”“`到目前
为止”。不表示距离,而表示时间。相当于(till now); 用于现在完成时态。但how many hours
of 表示以小时计数某事物的总量反复出现,不一定是持续发生的。How long were you in
Shanghai last year ? —— Two weeks. How many hours of reading do you do every day?
(二)【现在完成时五大考点】
【1】时间状语:just, never , ever, already, before, yet , ever since, lately 和表示过去至现在做过某事几次的词语so far , recently , in the past / last + 一段时间 ;over the last …year ,for +一段时间 ;since +时间点(含从句),since after …. 但just now (= a moment ago ) ①表示“刚才”用于一般过去时。②表示“现在”相当于now,用于一般现在时。③表示“过一会儿”用于一般将来时。
【2】 基本概念:现在完成时态主要强调过去发生的动作对现在的影响,以及过去发生的动作还未结束,一直持续到现在或将来,重点在于对现在的影响。(无时间状语、需要从上下文认真去分析才行)。
【3】与一般过去时态的区别:①现在完成时强调现在的情况,不能和表示过去的时间状语(yesterday , last night , three weeks ago , in 1990等连用。② 一般过去时态:强调过去的动作或状态和现在不发生关系。它只与表示过去时间状语(yesterday; last night; three weeks ago; in 1990 )等连用。
【4】①have been in +地点:表示“在某地(多长时间 )”常与表示一段时间的状语连用②have been to +
地点:表示“曾经去过某地”但现在已不在那个地方了(多指在说话现场)③have gone
to +地点:表示“去了某地”指主语已不在说话的现场可能到了去的 地方,也可能在路
程中。
【5】非延续性动词的用法:它在现在完成时态中不能与for 和since 引导的表示一段时间的状语连用。如:come, go, arrive, leave, begin / start ,open, buy, die, borrow, sell,lend , close , get to. join 等。
【6】解决的办法有三种:一是用过去时态来翻译句子。二是该动词的 相应的 延续动词来代替。(延续性动词:live / stay ;know ; study ; work ; keep ; sleep ; be 等。)三是用It is +一段时间+ since从句来翻译。
说明:现将非延续性动词及替换形式归纳如下:⑴ 用状态动词替代非延续性动词。注意:在否定句中,非延续性动词已成为一种能够延续的状语,因此可和表示一般时间的状语连用。
① come —— be here ⑨ come to —– be in / at
② leave —–be away from ⑩ go out —– be out
③ begin/start —– be on ⑾ put on—— wear
④ borrow —– keep (12) get to know——- know
⑤ die —— be dead (13) catch a cold —— have a cold
⑥ join —— be in/a(an) (14) fall asleep / go to sleep——- be asleep / sleep
⑦ become—— be (15) arrive in / at —— be in at
⑧ marry —– be married to sb (16) buy —— have
⑵ 用系表结构替代句中谓语和其它成分。
⑶ 一般过去时替代现在完成时。同时将for 短语改为ago短语
【7】例外:① 时间段+later 表示“经过一段时间以后”。如: in ten minutes later 十分钟之后
② after + 时间段:只用于一般过去时态中。如:after a short time 一段时间之后;但“in + 一段
时间”用于将来时。③ so far有时也可以与现在时强调现在的情况和过去时(强调过去的动作或情况)
连用。 So far you are right.
【三】 how often 提问频率是多久?答语:Once/Twice./Very often./Sometimes./Never…
how much 提问价格是多少?
how many 提问……多少?
how long 提问具体事物的长度和时间长度?
how soon 提问“需要多长时间”;其谓语动词用终止性动词,时态用一般将来
时。其答语:In a week/month…
how far away …? 提问距离有多远?相当于:How many kilometers is it from …to…?
例如:(1)how far away…… (2) how many kilometers
①—– How far away are man-made satellites from the earth?
—– They’re 8,000 kilometers away from the earth .
②—–How far away is Britain from France ? —-It’s only 30 kilometres away from France .
③—–How many kilometers is it by train from Kunming to Guangzhou ? —–2,216
④—–How many kilometres by train is it from Nanjing to Wuhan ? —-1,229.
17. 反意疑问句:对陈述句所说的情况提出相反疑问的句子。它由两部分组成,前一部分
是陈述句,后一部分是省略的问句。如前一部分用肯定,后一部分用否定,如前一部分
用否定,后一部分用肯定。注意:反意疑问部分的动词时态、人称、含义都要与陈述部
分动词保持一致。当陈述句中含有表否定意义的词few; little; never; hardly;scarcely;
seldom;no;not等构成反意疑句时,附加疑问句应用肯定式。例句:You can speak
Greek, can’t you? —– She is a League member, isn’t she? —– Yes, she is.
① a great many 语气比强;表示“很多,非常多”跟可数名词复数。
I have a great many books to read.
18. ② a great deal of 大量多;非常多跟可数名词复数
She spent a great deal of time studying English.
③ plenty of 足够多;许多;大量。跟可数名词或不可数名词。
There are plenty of trees on the campus.
There is plenty of time.
21.比较代词 anyone & anybody & none & no one的用法:
⑴ anyone/anybody一般作单数处理。当指普遍现象而非个别特殊情况;表示“全部,毫无例外”。也作复数处理。作主语部分时,后面不宜用否定式的谓语动词,应将该词改为none/no one /nobody+谓语动词肯定形式。Hardly anyone/ anybody/ anything …..表示“简直没有什么人(事物)”。
⑵ no one 表示“没有人或物,”当他作主语时,谓语动词用单数形式,其后不能接of,注意两个单词不能写成一个。相当于nobody,常用于回答who引导的问句。
⑶ none (作代词)表示:“没有人或物”,指三个或三个以上的人或物。当它作主语时,谓语动词可用单复数形式,其后可接of,表示全部否定,但not all表示部分否定;意义为“未必全部都常”。回答How many / much 提问的句子。 None has left there. None of them have left there. Who came to see me just now? —– No,one. —– How many people came just now? —– None.
⑷ neither of + 名词复数作主语时,谓语动词用单数。
22.在英语句子中,为了避免重复,通常用it , one , that , those 和 so 来替代上文提到的
人或事物:(1)It 代替“the+名词”,指前面提过的同一事物。(2)表示人时一般用he,
表示物时一般用it,但在下列情况下,常用it来表示人:指心目中的人;或指说话者对
谈及的人不清楚或只闻其声,不见其人。比如敲门,打电话等,或弄不清性别,尤其指
婴儿。等等。(3)one替代“a/an+单数可数名词”,指前面提到的同类事物中的一个。one
之前可用描绘性形容词,以及the , this , that , which , either等词修饰.one 的复数形式是
ones,它一般不能直接放在名词所有格、物主代词、数词以及some ,several ,these ,those ,
dozen , own , a 等词之后。除非前面有描绘性形容词。如:a new one / your red ones. one 前
用了the ,可替代带有前置或后置定语的可数名词,指特定的人或事物。(4)that 带后
置定语时,可替代句中某一个不可数名词。that可用来指代前句全部。(5)so 代替前句
中提到的事物. so用在动词think / expect / hope / believe / guess / suppose 后,替代一个起
从句作用的短语。
23. happenings发生的事情; doings所做的事; greetings问候; surroundings环境
