One hundred and thirteen million Americans have at least one bank-issued credit card. They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and they make many banking services available as well. More and more of these credit cards can be read automatically, making it possible to withdraw or deposit money in scattered locations, whether or not the local branch bank is open. For many of us the “cashless society” is not on the horizon---it’s already here.

While computer offer these conveniences to consumers, they have many advantages for sellers too. Electronic cash registers can do much more than simply ring up sales. They can keep a wide range of records, including who sold what, when and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how far they are moving. Decisions to reorder or return goods to suppliers can then be made. At the same time these computers record which hours are busiest and which employees are the most efficient, allowing personnel and staffing assignments to be made accordingly. And they also identify preferred customer for promotional campaigns. Computers are relied on by manufacturers for similar reasons. Computer analyzed marketing reports can help to decide which products to emphasize now, which to develop for the future and which to drop. Computers keep track of goods in stock, of raw materials on hand, and even of the production process itself.

Numerous other commercial enterprises, from theaters to magazine publishers, from gas and electric utilities to milk processors, bring better and more efficient services to consumers through the use of computers.

1. From the last sentence of the first paragraph we learn that ___________.

A. in the future all the Americans will use credit cads

B. credit cards are mainly used in the United States today

C. nowadays many Americans do not pay in cash

D. it is now more convenient to use credit cards than before

2. If computers record which hours are busiest and which employees are the most efficient, what will businessmen do?

A. They will fire some employees and raise the work efficiency.

B. They will arrange for different employees to do different jobs according to their abilities and performance.

C. They will assign more work for the employees to do.

D. They will allow the personnel to do whatever work they want to do.

3. What does the underlined phrase “ring up sales” in paragraph two mean?

A. make an order of goods.

B. record sales on a cash register.

C. call the sales manager.

D. keep track of the goods in stock.

4. What does the passage mainly discuss?

Steve and Yaser first met in their chemistry class at an American university. Yaser was an international student from Jordan. He wanted to learn more about American culture and hoped that he and Steve would become good friends. At first, Steve seemed very friendly. He always greeted Yaser warmly before class. Sometimes he offered to study with Yaser. He even invited Yaser to have lunch with him. But after the term was over, Steve seemed distant. The two former classmates didn’t see each other very often at school. One day Yaser decided to call Steve. Steve didn’t seem very interested in talking to him. Yaser was hurt by Steve’s change of attitude. “Steve said we were friends,” Yaser complained, “and I thought friends were friends forever.” Yaser was a little confused.

As a foreigner, he doesn’t understand the way Americans view friendship. Americans use the word “friend” in a very general way. They may call both casual acquaintances(相識的人；熟人) and close companions(伙伴) “friends”. These friendships are based on common interests. When the shared activity ends, the friendship may fade(逐漸消失). Now as Steve and Yaser are no longer classmates, their “friendship” has changed. In some cultures friendship means a strong lifelong bond between two people. In these cultures friendships develop slowly, since they are built to last. American society is one of rapid change. Studies show that one out five American families moves every year. American friendships develop quickly, and they may change just quickly as well. People from the United States may at first seem friendly. Americans often chat easily with strangers. But American friendliness is not always an offer of true friendship. After an experience like Yaser’s , people who’ve been in this country for only a few months may consider Americans to be fickle(易變的). Learning how Americans view friendship can help non-Americans avoid misunderstandings. It can also help them make friends in the American way.

1.According to the passage, ________made Yaser a little confused.

A. Steve’s inviting him to dinner

B. Steve’s cold attitude

C. Steve’s studying with him

D. Steve’s misunderstanding him

2.We can learn from the passage that_____.

A. Americans use the word “friend” in a very special way and like to develop a close friendship

B. American friendliness is always an offer of true friendship and is of great value

C. Americans think the friendship will last for ever, even though the shared activity ends

D. Americans always base their friendships with others on common interests

3.In Paragraph 2, the underlined word “they” refers to “_______”.

A. American friendships

B. American families

C. People from the United States

D. misunderstandings

4.This passage mainly tells us_____.

A. that people should not make friends with Americans.

B. that everyone needs friends.

C. the importance of keeping friendships

D. how Americans view friendship

Over the holidays, I took my three young children into a fancy chocolate shop to buy gifts. Halfway home, I noticed my 7-year-old son playing with a plastic noisemaker. Long story short: He had stolen the toy. I kept my cool -- even when he said, "but it was only $1.50, Mom!" --and explained why it was unacceptable to take things we didn't buy.

A few hours later, I marched my son back to the store with two dollars from his piggy bank. He walked embarrassedly to the counter and told the clerk that he had taken something without paying for it, that he was sorry to break it and that he would pay for it now.

I know exactly how terrible he was feeling. Returning to the scene of the crime is the same shame-causing punishment I received when I was five and stole something from a store. 1 remember my dad sending me back to return the item. It remains one of my clearest child－ hood memories. After that day, I never stole again. My dad taught me such an important lesson 30 years ago and I saw an opportunity to do the same for my son. But now I wonder if it was the fight thing to do.

"Returning to the store is absolutely the right thing to do," Laura Markham, Ph.D., a child psychologist and author of Peaceful Parent, Happy Kids, says. "Many children steal -- they' re not born knowing the rules so it' s our job to teach them."

And stay calm when you set them. "If you overreact or yell, you might create a fascination with the behavior and a willful child will be more likely to fight against you," she says. Having a child physically return the stolen item helps him or her grasp the situation -- and the consequence.

But don't talk about it for too long. "lf you continuously bring up the incident, the child will believe they' re a thief and that they' re bad," she says.

Only time will tell if this experience will have the same powerful effect on my son as it had on me, but at the same time I can rest if I haven' t dealt with the situation badly.

1.When the author' s son was caught playing with a stolen toy, he________.

A. responded calmly

B. felt very ashamed

C. didn't think it was a big deal

D. didn't admit stealing the toy

2.The author punished her son like that because __________.

A. her father asked her to do so

B. it had been popular for 30 years

C. she knew it was the right thing to do

D. the same punishment had worked on her

3.According to Laura Markham, if parents shout at their kids' stealing behavior, the kids may _______.

A. feel frightened

B. steal again

C. think they are bad

D. remember what happened clearly

4.What does the author think of Laura Markham' s words?

A. They are doubtful.

B. They are unacceptable.

C. They help her to stop feeling worried.

D. They have taught her a good lesson.

科目：高中英語 來源：2016屆遼寧大連第八中學(xué)高三上學(xué)期期中英語試卷（解析版） 題型：閱讀理解

The sound of a mosquito can mean trouble in many parts of the world. The bite of the mosquito can be deadly. The insects carry serious diseases like malaria (瘧疾). It is estimated that almost 630,000 people died from malaria and malaria­related causes in 2012, and most of these cases were in African countries.

In the United States, a group of California scientists are working to develop a more effective and less costly substance (物質(zhì)) to protect people from mosquitoes. The researchers are investigating the sense of smell in mosquitoes. They found the insects use the same receptor for identifying carbon dioxide in human breath as they do for the smell of our skin. Anandasankar Ray, who is leading the investigation, says scientists tested more than a million chemical compounds (化合物) until they found a substance called Ethyl Pyruvate. He says Ethyl Pyruvate makes the mosquitoes' receptors inactive. “When we apply Ethyl Pyruvate to a human arm and offer it to hungry mosquitoes in a cage, very few of the mosquitoes are attracted to the human arm because only a few of them are able to smell it out,” said Ray.

Genevieve Tauxe, a member of the research team, says it was not easy to find the neurons (神經(jīng)元) of noble cells that recognize both the smell of human breath and skin. “With the device used to examine the mosquito, we are able to insert a very small electrode (電極) into the part of the mosquito's nose, where its smelling neurons are and where the smell is happening,” said Tauxe.

Anandasankar Ray says a product based on Ethyl Pyruvate may cost less to produce than DEFT, the most effective chemical treatment now in use. He says DEFT is too costly for most people who live in areas affected by malaria.

“Perhaps by finding smells that can attack other target receptors, we will be able to improve upon DEFT and finally have the next generation of insect behaviour control products,” said Ray.

1.The underlined word in the second paragraph probably means ________.

A. a substance that protects people from mosquitoes

B. a piece of equipment that sends signals

C. a device that reacts to light

D. a sense organ that reacts to changes

2.According to the passage, Ethyl Pyruvate can ________.

A. kill the mosquitoes' smelling neurons

B. cause the mosquitoes to lose their senses of smell

C. result in the inactiveness of the mosquitoes' receptors

D. make the mosquitoes uninterested in human breath and skin smell

3.Which of the following would be the best title for the passage?

A. Ethyl Pyruvate—an Insect Behaviour Control Product

B. Malaria—a Serious Disease Causing 630,000 Deaths

C. Scientists Find a New Substance to Fight Mosquitoes

D. A New Generation of DEET Has Been Developed to Kill Mosquitoes

4.This passage most probably appears in ________.

A. a textbook of medical schools

B. a collection of doctors' essays

C. the column of newspaper ads

D. the health column of a magazine

Japanese students work very hard but many are unhappy. They feel heavy pressures from their parents to do well in school. Most students are always being told by their parents to study harder so that they can have a wonderful life. Though this may be good ideas for those very bright students, it can have very bad results for many students who are not quick enough at learning.

Unfortunately, a number of students killed themselves. Others are after comfort in using drugs. Some do bad things with trouble-makers and turn to crime. Many of them have tried very hard at school but have failed in the exams and have disappointed their parents. Such students feel that they are less important and leave school before they have finished their study.

It is surprising that though most Japanese parents are worried about their children, they do not help them in any way. Many parents feel that they are not able to help their children and that it is the teachers’ work to help their children. To make matters worse, a lot of parents send their children to special schools called juku-cram schools. These schools are open during the evening and on weekends, and their only purpose is to prepare students to pass exams. They do not try to educate students in any real sense of the real world. It thus comes as a shock to realize that almost three quarters of the junior or high school population attend these cram schools.

Ordinary Japanese schools usually have rules about everything from the students’ hair to their clothes and things in their school bag. Child psychologists now think that such strict rules often lead to a feeling of being unsafe and being unable to fit into society. They regard the rules as being harmful to the development of each student. They believe that no sense of moral values is developed and that students are given neither guidance nor training in becoming good citizens.

1.A lot of Japanese students are unhappy at school because_______.

A. they work very hard

B. they find they can't do well at school

C. they feel unimportant

D. they are under too much pressure

2.Because of their failure at school, some students take drugs to .

A. kill themselves B. seek comfort

C. disappoint their parents D. make trouble

3.In juku-cram schools students_________.

A. are taken good care of by the teachers

B. feel no pressure

C. are trained to pass exams

D. can learn a lot of useful things

4.In ordinary Japanese schools,______________ .

A. there are strict rules

B. students feel safe

C. students can do anything

D. learning is not important

In a movie, a woman reads a storybook to her friend’s daughter. As they approach the last page, she reads, “… and Cinderella and the prince lived happily ever after.” She closes the book and looks at the young girl, adding, “ You know, things don’t always happen like this in real life, I just think you should know that now.”

We were all raised on fairy tales with glass slippers, brave princes and magic! It didn’t take too long to realize that stories like that aren’t necessarily true. In real life, you learn that glass slippers are really uncomfortable, no prince is perfect and magic doesn’t always work.

So what do you do when the way you planned things is not the way they turned out?

Know that parts of your fairy tale have already been written, and sadly, there’s not much you can do about those first few chapters. You didn’t get the best start. Your trust was unexpectedly betrayed (背叛). You didn’t get the job. Whatever falls and failures happened in your past, there’s still more to the story.

Your life has a lot of contributors (投稿者), and you are the editor-in-chief. You take what’s there and create the masterpiece (杰作). All the good pages and the bad can come together to make a beautiful adventure.

When you find yourself wishing your life was more like the fairy tales, remember that in some ways it already is. There will be dragons, bad witches, great romances, winding roads and friends to help you along the way. Live your life carefully and positively as if you are writing a long story. Whether it’s a comedy, tragedy or a little of both, the pen is in your hand. How it ends is all up to you.

1.According to the first paragraph, we know the woman is __________.

A. wise B. cruel C. brave D. patient

2.Why does the author raise the question in Paragraph 3?

A. To compare different ideas

B. To express the doubts of life.

C. To introduce points for discussion.

D. To describe the conditions in real life

3.Which of the following may NOT often appear in fairy tales?

A. Glass slippers B. Winding roads

C. Sad endings D. Bad witches.

4.What is the message expressed in the passage?

A. Be positive about life

B. Write your own stories.

C. Parents should tell fairy tales to their kids

D. There are many problems in school education
