We can slow down aging. That is the message Dr. Shen Ziyin wants to give the world. And the Chinese doctor claims that he has found an answer to the problems of aging. His solution is a herbal medicine(草藥)to slow the process of aging.
Dr. Shen Ziyin has been trained in Western medicine. At the same time he studied traditional Chinese medicine. And, he has been working for the past forty years to put together the best of both and find a cure for aging. He has taken a hint from the ancient Chinese medicine system called “Shen”.
According to Shen, it is the kidney(腎臟)which adjusts the functioning of the body as well as its aging process. It is responsible for the level of activity that the human bodies go through. Studies conducted by Dr. Shen show that herbal medicine based on the Shen system slows the aging process, says a report in the Telegraph newspaper. We notice that when people grow old, they have reduced strength, loss of hair, backache, weakness, wrinkles and so on. This happens because when people grow old, their bodies produce T-cells. These T-cells contain a particular substance(物質)called Fas. Fas makes the cells in the body destruct themselves.
So the only way to slow down aging is to slow the production of T-cells in the body. This can happen if people eat low calorie food. Then the body is not active enough to produce extra T-cells. But, is going hungry all the time a good price to pay for staying young? This is where Dr. Shen’s herbal medicine comes in. But how effective it will be, only time can tell.
【小題1】 How did Dr. Shen find the solution to the problem of aging?

A.By studying Western medicine.
B.By learning traditional Chinese medicine.
C.By combining both Western and Chinese medicine.
D.By doing research on both Western and Chinese people.
【小題2】What plays the most important role in keeping people young according to Shen?
A.Medical treatment.
B.People’s good kidney
C.Positive life attitude.
D.Level of people’s activity.
【小題3】The reason why people become old is that_____.
A.their bodies produce T-cells
B.they become weaker and weaker
C.they have reduced strength, loss of hair
D.their bodies are unable to fight diseases
【小題4】 We can probably learn from the passage that______.
A.producing more low calorie food allows people to keep young
B.the more Chinese herbal medicine people drink, the better for health
C.people should try to quicken the production of T-cells in the body
D.it remains unknown how effective Dr. Shen’s herbal medicine is

Almost all cultures celebrate the end of one year and the beginning of another in some way. Different cultures celebrate the beginning of a new year in different ways, and at different times on the calendar.
In Western countries, people usually celebrate New Year at midnight on January 1st. People may go to parties, dress in formal clothes -- like tuxedos (小禮服) and evening gowns, and drink champagne at midnight. During the first minutes of the New Year, people cheer and wish each other happiness for the year ahead. But some cultures prefer to celebrate the New Year by waking up early to watch the sun rise. They welcome the New Year with the first light of the sunrise.
It is also a common Western custom to make a New Year’s promise, called a resolution. New Year’s resolutions usually include promises to try something new or change a bad habit in the new year.
Many cultures also do special things to get rid of bad luck at the beginning of a new year. For example, in Ecuador, families make a big doll from old clothes. The doll is filled with old newspapers and firecrackers. At midnight, these dolls are burned to show the bad things from the past year are gone and the new year can start afresh (again). Other common traditions to keep away bad luck in a new year include throwing things into rivers or the ocean, or saying special things on the first day of the new year.
Other New Year traditions are followed to bring good luck is to eat grapes on New Year’s Day. The more grapes a person eats, the more good luck the person will have in the year. In France, people eat pancakes for good luck at New Year. In the United States, some people eat black-eyed peas (豇豆) for good luck -- but to get good luck for a whole year you have to eat 365 of them!
【小題1】Which culture celebrates New Year in the morning?

A.The United States. B.Spain.
C.France.D.The passage doesn’t say.
【小題2】What is a resolution?
A.Something you burn.B.Something you eat.

The UK has a well-­respected higher education system and some of the top universities and research institutions in the world. But to those who are new to it all, sometimes it can be confusing.
October is usually the busiest month in the college calendar. Universities have something called Freshers’ Week for their newcomers. It’s a great opportunity to make new friends, join lots of clubs and settle into university life.
However, having just left the comfort of home and all your friends behind, the prospect(前景)of meeting lots of strangers in big halls can be nerve-­wracking(令人頭痛的). Where do you start? Who should you make friends with? Which clubs should you join?
Luckily, there will be thousands of others in the same boat as you worrying about starting their university social life on the right foot. So just take it all in slowly. Don’t rush into anything that you’ll regret for the next three years.
Here is some top advice from past students on how to survive Freshers’ Week:
●Learn rules. Make sure you know British social etiquette(禮節). Have a few wine glasses and snacks handy for your housemates and friends.
●Be kind. Sometimes cups of tea or even slices of toast can give you a head start in making friends.
●Be sociable. The more active you are, the more likely you’ll be to meet new people than those who never leave their room.
●Bring a doorstop. Keep your door open when you’re in and that sends positive messages to your neighbors that you’re friendly.
So with a bit of clever planning and effort, Freshers’ Week can give you a great start to your university life and soon you’ll be passing on your experience to next year’s new recruits
【小題1】Which of the following statements is FALSE according to the passage?

A.October is generally the busiest month for universities.
B.It’s a good idea to have a doorstop.
C.A bit of planning can make Freshers’ Week easier.
D.The first week of your every year at university is called Freshers’ Week.
【小題2】The underlined word “recruits” in the last paragraph refers to     
A.coursesB.freshersC.neighborsD.challenges
【小題3】We can infer from the 4th paragraph that     
A.the newcomers usually miss the days living at home
B.most of the students in the UK spend three years in universities
C.many freshers are worried about how to fit university life
D.all the new students will make new friends and join certain clubs
【小題4】Why does the author suggest having wine glasses and snacks handy?
A.To pass the busy university life.
B.To help make friends with other freshers.
C.To show yourself a drinker as others.
D.To pass the time in a happy way.
【小題5】The main purpose of the passage is to     
A.tell the newcomers how to make a new start in universities
B.introduce something about higher education system of the UK
C.discuss something about the Freshers’ Week in the UK
D.advise the freshmen how to behave well in the beginning

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. Interestingly, 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 let 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 them —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(購物禮券)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 in 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 booking 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.
【小題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
【小題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
【小題3】What does the writer recommend to create customer delight?
A.Calling customers regularly
B.Giving a “thank you” note
C.Delivering a quicker service
D.Promising more gifts
【小題4】If a manager should show his empathy (Paragraph 6), 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.”
【小題5】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
【小題6】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

Eating foods high in trans-fats(fats present in artificial form in industrially-produced cakes and fast food...) and saturated (飽和的) fats increases the risk of depression, according to a Spanish study, confirming previous studies that linked “junk food” with the disease. Researchers also showed that some products, such as olive oil, can fight against the risk of mental illness.
Authors of the wide-reaching study, from the universities of Navarra and Las Palmas, followed and analyzed the diet and lifestyle of over l2,000 volunteers over six years. When the study began, none of the participants had been diagnosed with depression; by the end, 657 of them were new sufferers.
“Participants with an increased consumption of trans-fats presented up to a 48 percent increase in the risk of depression when they were compared to participants who did not consume these fats,” the head study author said. “The more trans-fats were consumed, the greater harmful effect they produced in the volunteers.”
The research team found, at the same time, that after assessing the effect of polyunsaturated fats made up of larger amounts of fish and vegetable oils and olive oil, these products are associated with a lower risk of suffering depression.
The report, published in the online journal PLOS ONE, noted the research was performed on a European population that enjoys a relatively low intake of trans-fats—making up only 0.4 percent of the total energy taken in by the volunteers. “Despite this, we observed an increase in the risk of suffering depression of nearly 50 percent,” said researcher Miguel Martinez. “On this basis we think it of great importance to take this effect into account in countries like the United States, where the percentage of energy derived from these fats is around 2.5 percent.”
The report pointed out that the current number of depression sufferers in the world is around l50 million people, and has increased in recent years. This rise is attributable, according to the authors, “to great changes in the sources of fats consumed in Western diets, where we have replaced certain types of beneficial fats in nuts, vegetable oils and fish with the saturated and trans-fats found in meats, butter and other products such as mass-produced cakes and fast food.”
【小題1】What's the best title of the text?

A.Junk Food and DepressionB.Depression Prevention
C.Types of Fats and DepressionD.Depression Research
【小題2】Which of the following increases the risk of suffering depression?
A.Fish. B.Vegetable oil.C.Olive oil.D.Butter.
【小題3】The study tells us that         .
A.2.5% Americans suffer mental illness
B.l2,000 volunteers in Navarra took part
C.a minority of participants became new sufferers
D.l50 million Europeans enjoy a healthier lifestyle
【小題4】The underlined word “derived” in Paragraph 5 is closest in meaning to         .
A.obtained B.chosenC.separatedD.preserved
【小題5】More and more Westerners are suffering depression because         .
A.they have less time for exercise
B.they eat more nuts, vegetable oils and fish
C.the sources of fats in their diets have changed
D.less meat, butter, and cakes are included in their diets
