第三部分:閱讀理解(共20小題;每小題3分,共60分)
閱讀下列短文,從每題所給的A、B、C、D四個選項中,選出最佳選項。
A
Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Vi­olence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive(重溫) these experiences in nightmares.                       
Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce, or possibly erase the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body re­leasing chemicals that fix memories in the brain. So far the research had suggested that only the emo­tional effects of memories may be reduced, not that the memories are erased.
The research has caused a great deal of argument. Some think it is a bad idea, while others support it. Supporters say it could lead to pills that prevent or treat soldiers’ troubling memories after war.
They say that there are many people who suffer from terrible memories. “Some memories can ruin people’s lives. They come back to you when you don’t want to have them in a daydream or nightmare. They usually come with very painful emotions.” said Roger Pitman, a professor of psychiatry (精神病學(xué)) at Harvard Medical School. "This could relieve(減緩) a lot of that suffering.”
But those who are against the research say that changing memories is very dangerous because memories give us our identity. They also help us all avoid the mistakes of the past. “All of us can think of bad events in our lives that were horrible at the time but make us who we are. I'm not sure we’d want to wipe those memories out.” said Rebecca Dresser, a medical ethicist (倫理學(xué)家).
Some people fear that although the drug would first be used in only very serious cases, it would be­come more and more common.“People always have the ability to misuse science,” said Joseph LeDoux, a New York University memory researcher. “All we want to do is help people have better control of memories.”
56. The underlined word “it” in paragraph 4 refers to “_____.”
A. the new drug                      B. the research into the drug
C. the memory                        D. the chemical in the drug
57. Which of the following is Not the opinion of the supporters?
A.The pill can erase all the memories in the past.
B.Some memories can ruin people's life. The pill can relieve emotional suffering.
C. The pill can also help many other types of people who suffer from terrible memories.
D. The pill can prevent or treat troubling memories in soldiers after war.
58. Which of the following is Not the opinion of the opponents (反對者) ?
A. Our memories give us our identity.
B. The memories help humanity avoid mistakes of the past.
C. The drug should be used in only very serious cases.
D. People may not be sure whether they want to wipe the memories out.
59. Which of the following statements might be the main idea of the text?
A. People often suffer from bad memories.   
B. The nightmares are terrible.
C. Forget bad memories and be happy.
D. The research has caused a heated argument.

Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict,” he jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled.” Today David wears casual clothes—khaki pants and sports shirt—to the office. He hardly ever wears a necktie. “I’m working harder than ever,” David says, “and I need to feel comfortable.”

More and more companies are allowing their office workers to wear casual clothes to work. In the United States, the change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday, but only on Friday. This became known as “dress-down Friday” or “casual Friday”. “What started out as an extra one-day-a-week benefit for employees has really become an everyday thing.” said business consultant Maisly Jones.

Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code. “A lot of young people don’t want to dress up for work,” says the owner of a software company, “so it’s hard to hire people if you have a conservative dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Strauss Company, 85 percent of employers said that they believe that casual dress improves employee morale(士氣). Only 4 percent of employers said that casual dress has a negative effect on productivity. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.”

1.David Smith refers to himself as having been “a clothes addict,” because __________.

A.he often wore khaki pants and a sports shirt

B.he couldn’t stand a clean appearance

C.he wanted his clothes to look neat all the time

D.he didn’t want to spend much money on clothes

2.David Smith wears casual clothes now, because __________.

A.they make him feel at ease when working

B.he cannot afford to buy expensive clothes

C.he looks handsome in casual clothes

D.he no longer works for any company

3.According to this passage, which of the following statements is FALSE?

A.Many employees don’t like a conservative dress code.

B.Comfortable clothes make employees more productive.

C.A casual clothes code is welcomed by young employees.

D.All the employers in the U.S. are for casual office wear.

4.According to this passage, which of the following statements is TRUE?

A.Company workers started to dress down about twenty years ago.

B.Dress-down has become an everyday phenomenon since the early 1990s.

C.“Dress-down Friday” was first given as a favor from employers.

D.Many workers want to wear casual clothes to impress people.

5.In this passage, the following advantages of casual office wear are mentioned except ______.

A.saving employees’ money

B.making employees more attractive

C.improving employees’ motivation

D.making employees happier

科目:高中英語 來源:2012-2013學(xué)年山東省樂陵市高三10月月考英語試卷(解析版) 題型:閱讀理解

In the more and more competitive service industry , it is no longer enough to promise customer satisfaction. Today , customer “delight” is what companies are trying to achieve in  order to keep and increase market share.

It is accepted in the marketing industry , and confirmed by a number of researches, that customers receiving good service will promote business by telling up to 12 other people : those treated badly will tell their tales of woe to up to 20 people, 80 percent of people who feel their complaints are handled fairly will stay loyal

New challenges for customer care have come when people can obtain  goods and services through  telephone call centers and the Internet. For example , many companies now have to invest(投資)a lot of money in information technology and staff training in order to cope with the “phone rage”—caused by delays in answering calls ,being cut off in mid-conversation or left waiting for long periods.

“Many people do not like talking to machines ,”says Dr . Storey Senior Lecturer in Marketing at City University Business School. “Banks, for example, encourage staff at call centers to use customer data to establish instant and good relationship with them .The aim is to make the customer feel they know you and that you can trust— the sort of comfortable feelings people have during face-to-face chats with their local branch manager.”

Recommended ways of creating customer delight include: under-promising and over-delivering  (saying that a repair will be carried out within five hours ,but getting it done within two );replacing a faulty product immediately : throwing in a gift voucher(購物禮卷)as an unexpected “thank you” to regular customers ;and always returning calls ,even when they are complaints.

Aiming for customer delight is all very well , but if services do not reach the high level promised , disappointment or worse will be the result . This can be eased by offering an apology and an explanation of why the service did not meet usual standards with empathy (for example, “I know how you must feel”) , and possible solutions (replacement , compensation or whatever fairness suggests best meets the case).

Airlines face some of the toughest challenges over customer care . Fierce competition has convinced them that delighting passengers is an important marketing tool, while there is great potential for customer anger over delays caused by weather , unclaimed luggage and technical problems .

For British Airways staff , a winning telephone style is considered vital in handling the large volume of calls about bookings and flight times. They are trained to answer quickly , with their name , job title and a “we are here to help” attitude. The company has invested heavily in information technology to make sure that information is available instantly on screen.

British Airways also says its customer care policies are applied within the company and staff  are taught to regard each other as customers requiring the highest standards of service.

Customer care is obviously here to stay and it would be a foolish company that used slogans such as "we do as we please”. On the other hand , the more customers are promised, the greater the risk of  disappointment.

1.We can learn from Paragraph 2 that       .

A.complaining customers are hard to satisfy

B.unsatisfied customers receive better service

C.Satisfied customers catch more attention

D.well-treated customers promote business

2.The writer mentions “phone rage”(Paragraph 3) to show that       .

A.customers often use phones to express their anger

B.people still prefer to buy goods online

C.customer care becomes more demanding.

D.customers rely on their phones to obtain services

3.If a manager should show his empathy (Paragraph6), what would he probably say?

A.“I know how upset you must be.”

B.“I appreciate your understanding.”

C.“I’m sorry for the delay.”

D.“I know it’s our fault.”

4. Customer delight is important for airlines because      .

A.their telephone style remains unchanged

B.they are more likely to meet with complaints

C.the services cost them a lot of money

D.the policies can be applied to their staff

5.Which of the following is conveyed in this article?

A.Face-to-face service creates comfortable feelings among customers.

B.Companies that promise more will naturally attract more customers.

C.A company should promise less but do more in a competitive market.

D.Customer delight is more important for airlines than for banks.

科目:高中英語 來源:2013屆湖北省高二上學(xué)期期中考試英語題 題型:閱讀理解

There are 70,000 pubs in England and Wales have several thousand more in Scotland.

Every country has its drinking shop, but none has an institution quite like the British pub. The most important feature of a good pub (which modern buildings hardly ever achieve) is a feeling of something private. It must have nooks and crannies, corners and snugs, where conversations and assignations can take place without the whole world listening in.

Most pubs have at least two separate bars. The “public bar” which is for ordinary and women is the basic drinking shop. The “l(fā)ounge bar” (or saloon bar) which is for traveling salesmen and “l(fā)adies” probably has a carpet on the floor and rather more comfortable decoration. There may be a difference of a few pence in the drink prices, although all pubs are required by law to put their price lists easily seen on display.

Pubs have been changing over the past few decades. More and more of them sell good, inexpensive food and are competing strongly with restaurants. Tea and coffee are often on offer and children are being made more welcome. The law says that no one under 14 may enter a pub, and between 14 and 18 they must be accompanied by an adult and may not buy or consume alcoholic drink. In reality some pubs, especially in country districts, welcome whole families. Some set aside special rooms for children and where there are gardens they are almost always welcome.

The most basic change, however, came about in the 1938 licensing laws which allowed pubs in England and Wales to open not just at lunch time and in the evening, but all day, from 11 a.m. to 11 p.m. (Scottish laws already permitted all day opening.)

1. Which of the following can be the best title?

   A. Pubs’ history                        B. Pubs in Britain

C. Changes of pubs                          D. Features of a good pub

2. According to the British people, what kind of pub is a good one?

    A. The one with all day opening time.

    B. The one with good and inexpensive food.

    C. The one with all kinds of people enjoying themselves.

    D. The one with different parts where people can have a private conversation.

3.In paragraph 4, we can learn that                        .

    A. pubs allow people above 14 to enter alone

    B. pubs never allow people under 18 to enter

    C. pubs don’t sell more expensive food than restaurants

    D. pubs often sell alcoholic drinks as well as tea and coffee

4.According to the passage, which of the following is NOT true?

    A. The law requires all the pubs have slightly different prices of drinks.

    B. Ordinary people and women are often having fun in the “public pub”.

    C. In some country pubs, children accompanied by their parents are always welcome.

    D. Scottish laws allow pubs to open not just at lunch time and in the evening, but all day.
