高考英语易错题解题方法大全(1):单项选择(上)

【示例1】_____ Jinan you see today is quite _____ different city from what it used to be.

A. The, 不填

B. 不填, a

C. The, a

D. A. a

【错解分析】典型错误B.错因分析:以为专有名称前不用冠词而误选B。

【解题指导】第一个空后有定语从句修饰特指今天的上海市,用the ; 是一座不同于过去的城市,所以第二个空应该用不定冠词。

【答案】本题的正确选项为C.

【练习1】—Has the little girl passed ______ P.E. test?

—She has tried twice, and the teacher will allow her to have _____ third try.

A. the; 不填

B. a; the

C. the; a

D. the; the 【错解分析】由于没有掌握序数词前用不定冠词表示“又一次,在一次”的意思而误选D。

【解题指导】本题考查序数词前用不定冠词的用法.第一空特指体育测试,用定冠词;她尽管两次都未通过,但教师允许她再考一次.a+序数词表示“又.再”,故选C.

【答案】C

【示例2】 His speech was hard to understand because he kept jumping from one topic to _____.

A. other

B. the other

C. the others

D. another 【错解分析】典型错误B.错因分析:选择依据可能是one … the other …这一常用结构

【解题指导】使用one … the other … 时,我们通常是针对两者而言的,即指“两者中的一个……,另一个……”;如果所谈论的情况不是针对两者而言的,而是针对多者而言的,那么我们就不宜在 one 后使用 the other,而考虑用 another。

【答案】本题的正确选项为D.

【练习2】It’s sometimes difficult to tell one twin from _____.

A. another

B. some other

C. other

D. the other 【错解分析】误选 A 原因是以为另一个应该用another。

【解题指导】twin 意为“孪生子之一”、“双胞胎之一”,即指两者之一,故用one … the other … 这一结构

【答案】D

【示例3】10. “He is said to be a wise leader.” “Oh, no, he is _____ but a wise leader.”

A. anything

B. anyone

C. anybody

D. anywhere

【错解分析】典型错误B、C 错因分析:因为句子主语指人,似乎只有B、C才与之一致

【解题指导】其实,正确答案应选A。因为 anything but 是习语,意为“根本不是”或“一点也不”,不仅可用于事物,也可用于人

【答案】本题的正确选项为A.

【练习3】 She rose from being a _______ to become a superstar.

A. somebody

B. nobody

C. something

D. nothing 【错解分析】本题误选D nothing是指无关紧要的东西,不指人

【解题指导】nobody指无足轻重的人,小人物,题干意思是“她从一个无名小辈成长为一个超级巨星。”

【答案】B

【示例4】 I agree with most of what you said, but I don't agree with _____.

A. everything

B. anything

C. something

D. nothing

【错解分析】典型错误:B 错因分析:由于没有读懂句意而以为本句是否定句anything用于否定句或疑问句,因而误选B。

【解题指导】前文的I agree with most of what you said(我同意你说的大部分

内容),but表示转折,其后的not与everything构成部分否定, 意为"不是所有的都同意"故选A。

【答案】本题的正确选项为A.

【练习4】______ likes money, but money is not ______.

A. Everyone, everything

B. Everyone, anything

C. Someone, nothing

D. Nobody, everything

【错解分析】学生可能会误以为否定句中用anything,而误选B

【解题指导】句意为“大家都喜欢钱,但钱不是万能的”因此应选A。

【答案】A

【示例5】There’s no from my bedroom window except for some factory chimneys.

A. view

B. scene

C. sight

D. look

【错解分析】典型错误B或C.错因分析:没有区分开具体的词义。

【解题指导】view: what can be seen from a particular place ,esp. fine natural scenery 自然美景,风景; scene: view as seen by spectator 景色; sight :thing (to be) seen , or worth seeing , esp. sth remarkable 奇观,壮观; look: act of looking 看.瞧.望.本句句意为:除了一些工厂的烟囱外,从我卧室看不到任何风景了.

【答案】本题的正确选项为A.

【练习5】Mr. Li doesn’t think that all bad language should be allowed. In his opinion, there are ______ that should be kept up.

A. degrees

B. levels

C. limits

D. standards 【错解分析】学生容易由于没有读懂句意而误选其他选项。

【解题指导】Mr. Li认为并非所有不标准的语言都可以使用.哪些可用,哪些不可用,应有一定的标准. 应用standards。

【答案】D

【示例6】Every boy and every girl here . Let’s have the meeting.

A. is

B. are

C. was

D. were

【错解分析】典型错误 A.错因分析:由于没有熟记主谓一致的规则而误以为Every boy and every girl后谓语动词用复数。

【解题指导】此题考主谓一致。Every(Each) boy and every(each) girl 是强调每一个人,因此应该看作单数形式。

【答案】本题的正确选项为A .

【练习6】 ---How did your students express their thanks to you on Teachers’ Day?

---A gift together with many flowers _______ sent to me .

A. is

B. are

C. was

D. were

【错解分析】由于没有掌握主谓一致的具体规则而误选D.

【解题指导】当主语后接with, together with, as well as, rather than, but, like等短语作定语时谓语形式不受定语的影响。因此,应用was。

【答案】C

【示例7】 If you _____ stop smoking, you can only expect to have a bad cough.

A. won’t

B. would not

C. do not

D. can not

【错解分析】典型错误 C.错因分析:误以为这是考查时态,根据“主将从现”规则而误选C。

【解题指导】其实,will 除了用作表示将来时的助动词外,还可用来强调愿意或不愿意。又如:

If you will wait a moment, I will fetch the money.

(如果你肯稍等片刻,我就把钱取来。) 但是在表示不肯或不愿意时,则只能使用won’t,不能使用 would not。

【答案】本题的正确选项为A.

【练习7】——Ms Lin looks rather a kind lady.

——But in fact she is cold and hard on us. You ____ believe it!

A. shouldn’t

B. wouldn’t

C. mustn’t

D. needn’t

【错解分析】学生如果不清楚would可以表示推测,而不是表示过去,就容易错选。

【解题指导】本题主要考查情态动词的意义和用法。选项A表示建议;选项B表示

推测;选项C表示禁止;选项D表示需求。根据句子的意思,本题正确答案为B。

【答案】B

【示例8】Our house is on the top of the hill , and in winter the winds be pretty cold .

A. must

B. ought to

C. can

D. need

【错解分析】典型错误A.错因分析:根据汉语思维,在山上冬天准是很冷而误选A。

【解题指导】此题考查情态动词。Can表示一种逻辑上的可能。理论上来说,冬天

山顶上的风会非常冷的。Must表示主观上把握性最大的猜测,意为“一定是”;

ought to表示推测性的结论,意为“应当是”;need意为“需要”。

【答案】本题的正确选项为C.

【练习8】Has it been warned that all the children in this area stay

at their homes until the Flu has been controlled ?

A. can

B. will

C. may

D. shall

【错解分析】由于没有掌握一些情态动词的特殊用法而误选。

【解题指导】此题考查情态动词一些特殊用法。第二第三人称在表达许诺、警告、

命令、意图、决心等时,需用情态动词shall,其含义为“必须”、“应该”。本

句意为“在流感得到控制以前,告诫这个地区所有的孩子必须待在家里吗?”。

【答案】D

【示例9】The life here is really very difficult , to tell you the truth ,

I haven’t completely __to it yet.

A. agreed

B. fitted

C. adjusted

D. adopted

【错解分析】典型错误D.错因分析:学生容易误以为adopted是“适应”的意思而

误选D。

【解题指导】实际上,adopt 是“收养,采纳”的意思,adapt才是“适应”的意

思,adjust to 也可以表示“适应”。在平时备考中应注意对这些形近词进行归纳比较。

【答案】本题的正确选项为C.

【练习9】If you don’t try your best to learn all subjects, you will ___ behind.

A. stay

B. leave

C. fall

D. remain

【错解分析】以为“落在后面”是 leave behind,而误选B。

【解题指导】其实,leave sb behind是“把某人落在后面”,在句中应用被动结构才行。而fall behind 也可以表示“落后”,没有被动。

【答案】C

【示例10】Single-parent usually____ some of the functions that absent adult in the house would have served under the financial crisis.

A. takes over

B. takes after

C. takes out

D. takes in

【错解分析】典型错误A.错因分析:学生对于take的相关搭配区分不够仔细所致。【解题指导】考查动词短语的词义辨析。句意:通常,单亲家庭中的孩子承担着所缺家长应完成的任务。take over接管;take after模仿;take out拿出,取出;take in分担(家人的工作)符合句意。

【答案】本题的正确选项为D.

【练习10】Modern forms of transportation and communication have done much to ______ the isolation(隔离)of life in Alaska.

A. break down

B. break out

C. break into

D. break through

【错解分析】由于没有区分break所组成的短语而误选。

【解题指导】考查动词短语的词义辨析。break down 出故障; break out 爆发;break into 强行闯入; break through冲破,克服,由句意可以得知,选break through最好。

【答案】D

P【示例11】rofessor White has written some short stories, but he is _________ known for his plays.

A. the best

B. more

C. better

D. the most 【错解分析】典型错误B或D.错因分析:误以为known的比较级为more known 【解题指导】well known的比较级和最高级通常是 better known和best known,有时也可以是 more well known 和 most well known,但通常不能是 more known 和most known。句中涉及的只有 stories 和 plays 两个对象,故应选比较级。

【答案】本题的正确选项为C.

【练习11】---“What do you think of the service here?”

---“Oh, _________ . We couldn’t have found a better place.”A. too bad B. sorry C. wonderful D. impossible

【错解分析】由于没有正确理解We couldn’t have found a better place的汉语意思而误选A。

【解题指导】We couldn’t have found a better place 可视为We couldn’t have found a better place than this place,其意为“我们不可能找到一个比这个地方更好的地方”,即“”这是我们所能找到的最好的地方”

【答案】C

【示例12】I forget where I read the article, or I _________ it to you now.

A. will show

B. would show

C. am going to show

D. am showing 【错解分析】典型错误A 错因分析:以为主句用的是一般时态,根据语感会选A. 【解题指导】根据上文的语境可知句中的 or 隐含有一个虚拟的条件,即 or=if I didn’t forget where I read the article(要是我没忘记我在哪儿读过这篇文章的话——但事实上忘了)

【答案】本题的正确选项为 B.

【练习12】_________ smoking, he would not have got cancer in the lung.

A. Was he given up

B. Had he given up

C. Did he give

D. If he gave up

【错解分析】由于审题不清会误选D。

【解题指导】由于主句谓语是would not have got,这表明是对过去事实作出的假

设,所以从句谓语应该是 had given up。当虚拟条件句中有 had, should, were 等

词时,通常可以省略 if,并将 had, should, were 提前置于句首

【答案】B

【示例13】Our house is on the top of the hill , and in winter the winds be pretty cold .

A. must

B. ought to

C. can

D. need

【错解分析】典型错误A.错因分析:根据汉语思维,在山上冬天准是很冷而误选A。

【解题指导】此题考查情态动词。Can表示一种逻辑上的可能。理论上来说,冬天

山顶上的风会非常冷的。Must表示主观上把握性最大的猜测,意为“一定是”;

ought to表示推测性的结论,意为“应当是”;need意为“需要”。

【答案】本题的正确选项为C.

【练习13】Has it been warned that all the children in this area stay

at their homes until the Flu has been controlled ?

A. can

B. will

C. may

D. shall

【错解分析】由于没有掌握一些情态动词的特殊用法而误选。

【解题指导】此题考查情态动词一些特殊用法。第二第三人称在表达许诺、警告、

命令、意图、决心等时,需用情态动词shall,其含义为“必须”、“应该”。本

句意为“在流感得到控制以前,告诫这个地区所有的孩子必须待在家里吗?”。

【答案】D

【示例14】The professor has written another book,________ of great importance to computer science.

A. which I think it is

B. and I think is

C. which I think is

D. when I think is

【错解分析】典型错误A.错因分析:误以为I think 后跟的是宾语从句。

【解题指导】其实,I think是插入语,去掉之后再分析可知答案A项中的it是多余的。

【答案】本题的正确选项为C.

【练习14】We should do more such exercises in the future, I think, _____ those we did yesterday.

A. as

B. like

C. about

D. than

【错解分析】有的学生会以为such as 是固定搭配而选择A。

【解题指导】本题中I think是插入语。exercises被more修饰,故应选than,构成比较结构more…than…。不能受such的影响而选A项。

【答案】D

【示例15】When cooking supper, ______.

A. there was a knock on the door

B. someone was knocking at the door

C. we heard a knock on the door

D. we heard someone is knocking at the door

【错解分析】典型错误B或D 错因分析:由于忽视了从句省略成分应和主句

主语一致,而选B;选D是因为没注意时态一致。

【解题指导】 when引起的从句省略的成分与主句主语一致,很显然从句主语是人,而D项时态不一致,所以选C。

【答案】本题的正确选项为C .

【练习15】To get a better view of the stage, ____________________.

A.our seats had to be changed.

B.our seats were changed

C.our seats are changed

D.we had to change our seats.

【错解分析】忽视了目的状语的逻辑主语应该是人而误选ABC。

【解题指导】To get a better view of the stage的逻辑主语应该是人,而不是物,故选D。

【答案】D

单项选择题的十种快速解法

单项选择题的十种快速解法 选择题是一类客观性试题,由题干和供选答案两部分组成,能设置较广泛的情境,包括生物学基本概念、基本原理、基本规律、基本实验、基本计算及有关知识的应用等多个目标,因此,在高考生物试卷中占有很大的比例。然而有些学生在考试中或因选择题得分过低,或因选择题耗时过多,影响了其他题的解答,导致考分不理想。究其原因,主要是学生没有掌握选择题的特点。解答这类题的方法不当,思维方式欠妥等。笔者为此对快速解答单项选择题(通常为四选一)的一些经验作一浅谈,供参考。 一、直选法 这是解答选择题最基本的方法,其程序是依据题目衔给条件,借助已学的知识进行分析和判断,直接得出结论。 倒l:为研究果实贮藏效率与氧气浓度的关系,将质量相同的苹果果肉放在氧气浓度不同的密闭容器中,一小时后测定氧气的吸收量和二氧化碳释放量。结果如下表: 氧气相对值0 1% 2% 3% 5% 7% 10% 15% 20% 25% O2吸收量(mol) 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 1.0 CO2释放量(mol) 1.0 0.8 0.6 0.5 0.4 0.5 0.6 0.7 0.8 1.0 根据以上结果不能得出的结论是( )。 A.氧浓度为3%时,每小时葡萄糖有氧分解量为0.05mol B.氧浓度为5%时,每小时葡萄糖无氧分解量为0mol C.仓库中贮藏苹果时氧气相对浓度为5%时最好 D.贮藏苹果时还可以采取低温、干燥等措施 解折:本题因为D选项与题干由所说内容无关,可直接连出D项。A、B选项需根据有氧呼吸、无氧呼吸两个反应式进行定量计算可算出。 答案:D

二、找题眼法 找题眼法就是从多个已知条件中找出某一作为解题切入点的条件,从而得出答案的方法。其中最先使用的条件就是题眼。 例2:水溶性染色剂(PI),能与核酸结合而使细胞核着色,可将其应用于细胞死活的鉴别。细胞浸泡于一定浓度的PI中,仅有死亡细胞的核会被染色,活细胞则不着色,但将PI注射到细胞中,则细胞核会着色。利用PI鉴别细胞的基本原理是( ) A.死细胞与活细胞的核酸结构不同 B.死细胞与活细胞的核酸含量不同 C.细胞能分解染色剂 D.活细胞的细胞膜阻止PI的进入 解析:本题的切入点是活细胞的细胞膜是一层选择透过性腊会阻止染色剂的进入而不着色;如果细胞死亡,则细胞膜失去选择透过性,染色剂可以进入而使细胞核着色。所以本题的题眼是细胞膜的选择透过性,答案很快就出来了。 答案:D 三、信息转化法 对某些选择题,由于情境比较陌生,或内容比较繁琐,可通过思维转换,将题示信息转化为比较熟悉的,便于理解的形式,从而化陌生为熟悉,化难为易,迅速求解。 例3:以虫治虫是生态农业的重要内容,下图表示某一生态系统中四种生物所含有机物的总量,假设这四种生物只构成一条食物链。请问在一段时间内,如果甲的种群数量增加,其可能引起的后果是( )。 A.乙和丁的种群数量都增加 B.乙和丁的种群教量都减少 C.乙和丙的种群数量都减少

So he is(√) [析] “so+be动词/助动词+主语”的倒装结构表示前面所述情况也适用于后者,意为“……也是这样”;“so+主语+be动词/助动词”的陈述结构表示对前述情况的肯定,意为“……确实如此”。 19. 例--- He didn’t go to school yesterday, did he?-- _______, though he didn’t feel very well.

高考英语易错题大全附答案解析

高考英语易错题汇编(思维定势) 1. They ______ on the program for almost one week before I joined them, and now we _____on it as no good results have come out so far. A. had been working; are still working B. had worked; were still working C. have been working; have worked D. have worked; are still working 此题的时间参照点是before I joined them,,所以第一个空应该用过去完成进行时,第二个空根据时间now用现在进行时。 2. It would be a good idea to use a plastic bottle, ___cut off, as a container to grow young plants in. A. of which the top B. the top is C. the top of which D. with its top 此题是独立主格结构,如果题干改为 ____is cut off,答案则为A或C 3. ______ is it _____ has made Peter _____ he is today? A. What; that; that B. That; that; what C. What; what; that D. What; that; what 用还原法则为 It is what that has made Peter what he is today k可知是强调句式。 4. Before he went abroad,he spent as much time as he _____ English. A. could learning B. learned C. to learn D. could learn spend time (in) doing sth 如果改为he did what he ______, 则答案为could to learn. 5. The person we talked about ____ our school last week. A.visiting B.will visit C.visited D.has visited 此题中包含一个定语从句,the person既作先行词,又作句子的主语,要填入的应该是句子的谓语,根据后面的时间状语为last week,应选过去时。句中包含的定语从句we talked about中about虽为介词,但不影响主句的谓语,故应选C。 观察下面三个句子: □The pers on we spoke to ____ no answer at first. A.making B.makes C.make D.made 此题中也包含一个定语从句we spoke to,the person既作先行词,又作句子的主语,要填入的应该是句子的谓语,根据句子的需要,应选过去时。本题中的to为陷阱,实际上它属于定语从句中,而不影响主句的谓语动词。故D正确。 □The person we referred to(提及)____ us a report tomorrow. A.giving B.will give C.gave D.give 同上题一样,句中包含定语从句we referred to,所缺成份为句子的谓语,又根据句中的tomorrow,故用将来时。选B。 □The days we have been looking forward to ____ soon. A.coming B.will come C.came D.have come 同理,此句中的定语从句包含短语look forward to,虽然to 为介词,但并不影响主句的谓语动词,只是一个陷阱而矣。又根据句中的soon,应用将来时,故选B。 6. Not far from the club there was a garden, ____ owner seated in it playing bridge with his children every afternoon. A. whose B. its C. which D. that 答案为B。此题关键是理解seated这个单词,它是过去分词,而不是作谓语的过去式。它不能在句中谓语。所以后面句子不是一个非限制性定语从句,而是一个独立主格结构,故选代词its。 7. You should treat him (in) the way ____ suits him most. A. that B. in which C. / D. why 此题中先行词the way 后面的定语从句中充当主语。故只能选A。如果先行词the way有从句中充当
