Passage 1 CBBCC

If you have a chance to go to Finland, you will probably be surprised to find how “foolish” the Finnish people are.

Take the taxi drivers for example. Taxis in Finland are mostly high-class Benz with a fare of two US dollars a kilometer. You can go anywhere in one, tell the driver to drop you at any place, say that you have some business to attend to, and then walk off without paying your fare. The driver would not show the least sign of anxiety.

The dining rooms in all big hotels not only serve their guests, but also serve outside diners. Hotel guests have their meals free, so they naturally go to the free dining rooms to have their meals. The most they would do to show their good faith is to wave their registration card to the waiter. With such a loose check, you can easily use any old registration card to take a couple of friends to dine free of charge.

The Finnish workers are paid by the hour. They are very much on their own as soon as they have agreed with the boss on the rate. From then on they just say how many hours they have worked and they will be paid accordingly.

With so many loopholes(漏洞) in everyday life, surely Finland must be a heaven to those who love to take “petty advantages”. But the strange thing is, all the taxi passengers would always come back to pay their fare after they have attended to their business; not a single outsider has ever been found in the free hotel dining rooms. And workers always give an honest account of the exact hours they put in. As the Finns always act on good faith in everything they do, living in such a society has turned everyone into a real “gentleman”.

In a society of such high moral practice, what need is there for people to be on guard against others?

1. While taking a taxi in Finland, _____

A. a passenger can go anywhere without having to pay the driver

Passage 2 CBABD

There are many factors which may have an influence on adults and children being able to lead a healthy life.

Nowadays, people are very busy. Often, both parents work outside the home. Children are expected to take on more responsibility at home to help their parents. They also have sporting and leisure activities as well as school expectations.

The busyness also adds another factor: the need to use cars to get from one place to another quickly.

Today, society places a lot of emphasis on technology. Computers, DVDs. CDs, television, PlayStations and Xboxes have become major leisure activities, rather than traditional more active pursuits. This has led to a more sedentary lifestyle.

It is much more convenient at times to buy a quick takeaway rather than prepare a meal. The media constantly bombard(轰炸) their audience with …perfect? body images, the need to buy the most fashionable clothes, the most up-to-date computer games, the best places to visit and the best things to do.

Environments vary. We may be exposed to pollution , such as cigarette smoke. This can be harmful to people who suffer from breathing difficulties. Environments where passive smoking is unavoidable make it difficult to lead a healthy life.

Passage 5

This is a new type of advertisement becoming increasingly common in newspaper classified columns. It is sometimes placed among “situations vacant”, although it doesn?t offer anyone job, and sometimes it appears “situations wanted”, although it is not placed by someone looking for a job either. What it does is offer help in applying for a job.

“Contact us before writing your application”, or “Make use of our long experience in preparing your curriculum vitae (job history) or job history”, is how it is usually expressed. The growth and apparent success of such a specialized service is, of course, a reflection on the current high levels of unemployment. It is also an indication of the growing importance of the curriculum vitae, with the suggestion that it may now qualify as an art form in its own right.

There was a time when job seeker simply wrote letters of application. “Just put down your name, address, age and whether you have passed any exams”, was about the average level of advice offered to young people applying for their first jobs when I left school. The letter was really just for openers, it was explained, and everything else could and should be saved for the interview. And in those days of full employment the technique worked. The letter proved that you could write and were available for work. Your eager face and intelligent replies did the rest.

Later, as you moved up the ladder, something slightly more sophisticated was called for. The advice then was to put something in the letter which would distinguish you from the rest. It might be the aggressive approach. “Your search is over. I am the person you are looking for,”was a widely used trick that occasionally succeeded. Or it might be some feature specially designed for the job in view.

There is no doubt, however, that it is the increasing number of applicants with university education at all points in the process of engaging staff that has led to the greater importance of the curriculum vitae.

Passage 6 CDACD

A credit card can be useful. You could take it into a store and buy a television set or new furniture or clothing or anything you wanted. All you would have to do is to sign your name and take what you wanted out of the store without paying cash.

But there is a problem with the cards---they can be financial poison. These cards are just like the poisons we use on insects. If we use them carefully, they can be helpful; but if we use them too much, they can kill us. These cards can kill us financially just as real poison can kill our body.

For any money that the user does not pay each month, the credit card company changes a percentage of that amount in interest. The insect is added every month, so a bill that is not paid gets bigger and bigger.

Over 10 percent of the families in the United States are “overextended”. That is, they have more debt on their credit cards than they can pay.

Credit cards can be used for almost anything that money can buy. And they can even be used to pay for funerals. For some credit card users, a funeral may be the only solution to the debt problems they have caused for themselves by using credit cards.

Passage 8 DDBCC

Scientists in the United States have developed a computer program that say could provide an early warming of major earthquakes. The new system is designed to give a warming seconds before an earthquake strikes.

That may not sound like very long. However, it could give people time to get under a table. The flow of electric power or gas could be cut, air traffic controllers could warn away pilots. Even so-ca lled “smart buildings” could be designed to get ready.

Richard Allen of the University of Wisconsin and Hiroo Kananmori of the California Institute of Technology developed the program. They call it the Earthquake Alarm System. A report published in Science magazine describes it.

The system uses a mathematical program to measure information collected by instruments placed across the Los Angeles area. Southern California already has more than 150 stations that measure movements within the ground. The information they collect is sent to a high-speed computer.

The new system is designed to estimate the strength of the earthquake once the shaking starts. Areas directly above the center of the earthquake would have the least warning. Distant places might have as long as forty seconds.

Professor Allen notes that an early warning system for earthquakes would require a major campaign of public education. Then, another problem is the possibility of false alarms.

1. When an earthquake strikes, the new alarm system would give people enough time to______.

A) find shelter in “smart buildings”

B) tell pilots to land the airplanes

C) know the strength of the earthquake

D) turn off gas and electricity

2.The “earthquake Alarm System” described in the passage h as been developed by _______.

A) Richard Allen and his teacher Hiroo Kananmori

B) Hiroo Kananmori and his assistant Richard Allen

C) two scientists from the United States and Japan

D) two scientists from two universities in the US

3. The new alarming program_________.

A) is widely used in Winsconsin and California

B) is still in process of development

C) is especially useful for areas directly above center of the earthquake

D) gives warming at least forty seconds before the earthquake starts.

4. The new alarm system may be described as _________.

A) a program that analyzes data across the United States

B) a network of instruments placed across the United States

C) a program to collect information from 150 different stations

D) a very powerful computer that can do mathematical problems.

5. The writer of this passage has most probably used information from_________.

A) a meeting held at the California Institute of Technology

B) an interview with Professor Richard Allen

C) a report published in the Science magazine

D) an announcement made by a group of scientists.

Passage 9 CCBDD

Sign has become a scientific hot button. Only in the past 20 years have specialists in language study realized that signed languages are unique—a speech of the hand. They offer a new way to probe how the brain generates and understands language, and throw new light on an old scientific controversy whether language, complete with grammar, is something that we are born with, or whether it is a learned behavior. The current interest in sign language has roots in the pioneering work of one rebel teacher at Gallaudet University in Washington, D.C., the world?s only liberal arts university for deaf people.

When Bill Stokoe went to Gallaudet to teach English, the school enrolled him in a course in signing. But Stokoe noticed something odd among themselves, students signed differently from his classroom teacher.

Stokoe had been taught a sort of gestural code, each movement of the hands representing a word in English. At the time, American Sign Language (ASL) was thought to be no more than a form of pidgin English (混杂英语). But Stokoe believed the hand talk his students used looked richer. He wondered might deaf people actually have a genuine language and could that language be unlike any other on Earth It was 1955, when even deaf people dismissed their signing as substandard. Stokoe’s idea was academic heresy (异端邪说).

It is 37 years later. Stokoe—now devoting his time to writing and editing books and journals and to producing video materials on ASL and the deaf culture—is having lunch at a café near the Gallaudet campus and explaining how he started a revolution. For decades educators fought his idea that signed languages are natural languages like English, French and Japanese. They assumed language must be based on speech, the modulation (调节) of sound. But sign language is based on the movement of hands, the modulation of space. What I said, Stokoe explains, is that language is not mouth stuff—it?s brain stuff.

1. The study of sign language is thought to be ________.

A) a new way to look at the learning of language

B) a challenge to traditional views on the nature of language

C) an approach to simplifying the grammatical structure of a language

D) an attempt to clarify misunderstanding about the origin of language

2. The present growing interest in sign language was stimulated by _______.

A) a famous scholar in the study of the human brain

B) a leading specialist in the study of liberal arts

C) an English teacher in a university for the deaf

D) some senior experts in American Sign Language

3. According to Stokoe, sign language is ________.

A) a substandard language

B) a genuine language

C) an artificial language

D) an international language

4. Most educators objected to Stokoe?s idea because they thought _______.

A) sign language was not extensively used even by deaf people

B) sign language was too artificial to be widely accepted

C) a language should be easy to use and understand

D) a language could only exist in the form of speech sounds

5. Stokoe?s argument is based on his belief that _________.

A) sign language is as efficient as any other language

B) sign language is derived from natural language

C) language is a system of meaningful codes

D) language is a product of the brain

Passage 10 CAABC

“Congratulations, Mr. Jones, it?s a girl.”

Fatherhood is going to have a different meaning and bring forth a different response from every man who hears these words. Some feel pride when they receive the news, while others worry, wondering whether they will be good father. Although there are some men who like children and may have had considerable experience with them, others do not particularly care for children and spend little time with them. Many fathers and mothers have been planning and looking forward to children for some time. For other couples,pregnancy (怀孕) was an accident that both husband and wife have accepted willingly or unwillingly.

Whatever the reaction to the birth of a child, it is obvious that the shift from the role of husband to that of father is a difficult task. Yet, unfortunately, few attempts have been made to educate fathers in this resocialization process. Although numerous books have been written about American mothers, only recently has literature focused on the role of a father.

It is argued by some writers that the transition to the father?s role, although difficult, is not nearly as great as the transition the wife must make to the mother?s role. The mother?s role seems to require a complete transformation in daily routine (生活规律) and highly innovative (创新的) adaptation, on the other hand, the father?s role is less demanding and immediate. However, even though we mentioned the fact that growing numbers of women are working outside the home, the father is still thought by many as the breadwinner in the household.

1. According to the author, being a father ________.

A) brings a feeling of excitement to some men

B) has a different meaning for those who have daughters

C) makes some men feel proud and others uneasy

D) means nothing but more responsibilities

2. It is stated in the passage that ________.

A) some parents are not prepared to have a child

B) young couples do not like children at all

C) working couples do not have much time to take care of their children

D) many parents look forward to having a boy as their first child

3. In the second paragraph, the author ________.

A) criticizes fathers for not taking enough responsibilities in bringing up their

children

B) excuses the American writers for ignoring the difficulties of being a father

C) supports the idea that the chief role of a father is to earn money for the family

D) complains about the lack of social programs to help husbands adjust

themselves to being a father

4. The transition to the mother?s role requires that the wife ________.

A) change her life style in a highly innovative way

B) make a complete change in her everyday life to deal with the new situation

C) stay at home to take care of the baby

D) help her husband in his resocialization process

5. Some writers argue that with respect to the change of roles, fathers, compared

with mothers, ________.

A) have to shoulder more burdens

B) have to make more difficult adaptations

C) have an easier job to do

D) can usually do a better job

初三中考初中语文阅读理解专题训练含答案 一、现代文阅读 1.现代文阅读阅读下面文章,完成后面小题 向大海也能要“药” 刘诗瑶 ①前不久,由中国海洋大学、中国科学院上海药物研究所和上海绿谷制药联合研发的治疗阿尔茨海默症新药“甘露寡糖二酸”(GV—971)顺利完成临床Ⅲ期试验,在新药研制上迈过了最关键的一步。该药物是从海藻中提取的海洋寡糖类分子,其新颖的作用模式与独特的多靶作用特征,为阿尔茨海默症药物研发开辟了新路径。 ②海洋约占地球表面积的71%,是巨大的生物资源库。以海洋生物和海洋矿物中的有效成分为基础开发的药物就是海洋药物。据中国海洋大学、青岛海洋科学与技术试点国家实验室学委会主任管华诗院士介绍,目前认识和开发的海洋药物主要来自海洋生物资源。 ③人类主要生活在陆地上,所研发的药物主要来源于陆地,但使用多了,就有可能产生耐药性。于是,人们将目光转向了浩瀚深邃的海洋。 ④除了够新,海洋药物还够“奇”。据管华诗介绍,为了适应在深海环境中的生存、繁衍、防御等活动,深海生物进化出了独特的基因,耐寒耐热耐高压等,能够产生结构奇特、活性多样显著的海洋天然产物,它们为现代创新药物研发提供了重要结构信息,是肿瘤、心脑血管疾病、免疫性疾病、神经系统疾病等人类重大疾病药物先导化合物发现的重要源泉。 ⑤半个多世纪以来,全球共有13个海洋创新药物被批准上市,其中管华诗院士1985年开发上市的我国首个海洋新药藻酸双酯钠(PSS)就是其中之一。进入21世纪后,海洋药物的开发和上市速度明显加快,十几年间,先后有8个海洋药物被美国FDA(食品药品监督管理局)或欧盟EMEA(欧洲药品评估局)批准上市。到2016年,海洋药物的全球市场达到86亿美元,已成为蓝色经济发展中的重要一极。 ⑥据了解,世界各国尤其是美国、日本及欧盟等国家纷纷制订相应计划,斥巨资开发海洋生物资源,海洋药物已经成为国际医药领域竞争的热点。 ⑦但向大海要“药”,并不容易。 ⑧首先是采样难。要“药”的第一步是到海里获取海洋天然产物,海洋生物活性物质结构特异而复杂,且含量极微。这需要深海设备的支撑,这对于任何国家来说都是一笔不小的投入。其次是培养难,从海洋采集完生物资源,仅仅是完成了最前端步骤,还需在陆地上充分模拟海洋环境,对生物进行培养,延续研究。 ⑨“再次是研发难,从化合物到活性化合物、先导化合物、候选药物,最终通过Ⅰ、Ⅱ、Ⅲ期临床试验形成市场上的药物,链条上任何一个环节出问题,都会让新药‘夭折’。”自然资源部第三海洋研究所杨献文研究员表示,若无企业参与,单纯依靠高校和科研院所很难进行新药研发。 ⑩尽管困难重重,我国科研人员和制药公司依然坚持不懈地进行海洋药物开发,并取得了一定成果。自然资源部第三海洋研究所、中科院海洋所、中国海洋大学、中山大学等科研院所及高校都是海洋药物开发的重要力量。

高考英语专题题库∶阅读理解的综合题及答案

一、高中英语阅读理解 1.阅读理解 Most adults find it hard to recall events from their first few years of life and now scientists have found exactly when these childhood memories fade(消失). A new study has found that most three-year-olds can recall a lot of what happened to them over a year earlier, and these memories persist while they are five and six, but by the time they are over seven, these memories decline(衰退) rapidly. Most children by the age of eight or nine can only recall 35% of their experiences from under the age of three, according to the new findings. The scientists behind the research say this is because at around this age the way we form memories begins to change. They say that before the age of seven children do not have a sense of time and place in their memories. In older children, however, the early events they can recall tend to be more adult-like in the way they are formed. Children also have a far faster rate of forgetting than adults. The findings also help to explain why children can often have clear memories of events but then forget them just a couple of years later. The youngsters first visited the laboratory at the age of three and discussed six unique events from their past, such as family outings, trips to the zoo, and the first day of school. The children then returned for a second session between the ages of five and nine to discuss the same events. The researchers found that between the ages of five and seven, the amount of memories the children could recall remained between 63 -72 percent. However, the amount of information eight-to nine-year-old children could recall dropped to 35 and 36 percent. (1)What does the new study tell us? A.Childhood memories decline with years. B.Three-year-old kids are the cleverest. C.Childhood memories can fade easily. D.Some adults cannot recall past events. (2)What does the underlined word "persist" in Paragraph 2 mean? A.Change. B.Remain. C.Appear. D.Return. (3)What can we learn from Paragraph 4? A.Adults cannot have clear memories of past events. B.Children can think like adults when they get older. C.Children under 7 years old have different ways of forming memories. D.Children often forget things because they have no idea of time or place. (4)In the second session, nine-year-old children _________. A.refused to discuss the same events B.remembered all their family outings C.could recall 72 percent of their past events

秋天的香山公园 秋天的香山公园,以它独特的美迎接着众多的游人。 走进公园大门,放眼望去,峰峦重叠,挺拔壮观。山上长满了各种树木,枝叶浓密,人走进去,便淹没在其中了。 最引人注目的是那漫山遍野的红叶。近看红叶的形状不一,有长圆扁圆、扇形,还有三角形的。远看,山坡上树树交错,叶叶相连,层层叠叠相互辉映,映红了半边天空。在大片大片的鲜红中央杂着深黄色、褐色……就像千万只彩蝶上下飞舞,真是姿态万千,绚丽多彩。一阵爽人的秋风吹过,传来柔和的“沙沙”声,枝摇叶摆,像是在向游人频频招手。 人们不由赞叹:“多美呀!香山的红叶。” 香山公园里潺潺的流水也很动人。小路旁,石缝里,溪水愉快地流淌着。阳光洒在水面上,闪着耀眼的光芒。有时,溪水聚在几块碎石中间,静静地躺着,小鱼儿在你追我赶地嬉戏。 再看,路旁的花坛里,花儿展开笑脸,争芳斗艳。一串连成片,鸡冠顶起了花冠。那品种繁多的菊花,伸开了卷曲的花瓣;没有开放的花瓣紧缩着,像一个个彩球。不管是什么花,都散发出淡淡的清香。 美丽的香山公园,使游人流连忘返。 1.查字典。 “爽”用音序查字法应查音序,再查;用部首查字法应查部首,再查画。字典中的解释有:(1)明朗,清亮;(2)率直,痛快;(3)舒服;(4)违背。“爽人的秋风”中“爽”应取第种解释。

2.用“——”分别画出概括第3、4、5自然段意思的中心句。 3.读第3自然段,作者是从、、三方面描写红叶的。 4.第5自然段,写了、、三种花,是从、、三方面介绍的。 5这篇短文中,作者主要写了哪几种景物:,表现了作 者。 6、用“﹏﹏”划出首尾照应的句子。 公园一角 最引人注目的是公园的一角。这里有一个圆形的喷水池,池中有一座别致的假山。池里的水清润(rùn)得宛如一块天然的翡(fěi)翠,平滑无暇,清澈见底。当微风拂过水面时,水面上就泛起层层鱼鳞般的波纹。池中的假山是由好几块奇石巧妙地堆成,很精巧。假山顶端喷出一股又细又高的水柱。那水柱喷出后,又斜落下来,成了一串银白的水珠,晶莹耀眼。微风吹过,犹如点点白梅撒在水面上,荡漾起一圈圈小小的涟漪(yī),飘散在空中,仿佛给假山披上一层轻纱,格外美丽。 池中有许多色彩斑(bān)斓(lán)的金鱼,它们互相嬉(xī)戏,好不自在。瞧,一条花尾金鱼刚浮到水面上,嗖的一下,转头又钻入水底下去了。看,又来一条,眼睛大大的,鼓鼓的,穿着黑色的晚礼服,好像是要去参加隆重的盛会。它昂着头,不停地摆动着尾巴,像是在炫耀自己:“瞧,我多漂亮!”

大学英语一阅读理解 一、阅读理解(共505题,共101分) 1. Few laws are so effective that you can see results just days after they take effect. But in the nine days since the federal cigarette tax more than doubled—to $1. 01 per pack—smokers have jammed telephone “quit lines” acro ss the country seeking to kick the habit. This is not a surprise to public health advocates. They’ve studied the effect of state tax increases for years, finding that smokers, especially teens, are price sensitive. Nor is it a shock to the industry, which fiercely fights every tax increase. The only wonder is that so many states insist on closing their ears to the message. Tobacco taxes improve public health, health, they raise money and most particularly, they deter people from taking up the habit as teens, which is when nearly all smokers are addicted. Yet the rate of taxation varies widely. In Manhattan, for instance, which has the highest tax in the nation, a pack of Marlboro Light Kings cost $10.06 at one drugstore Wednesday. Charleston, S, C., where the 7-cent-a-pack tax is the lowest in the nation. The price was $4. 78. The influence is obvious. In New York, high school smoking hit a new low in the latest surveys—13.8%, far below the national average. By comparison, 26% of high school students smoke in Kentucky, Other low-tax states have similarly depressing teen-smoking records. Hal Rogers, Representative from Kentucky, like those who are against high tobacco taxes, argues that the burden of the tax falls on low-income Americans “who choose to smoke.” That’s true, But there is more reason in keeping future generations of low-income workers from getting hooked in the first place, As for today’s adults, if the new tax drives them to quit, they will have more to spend on their families, cut their risk of cancer and heart disease and feel better.
