Can money buy happiness? Yes, but only to a very (66) extent unless you learn how to put it to good use. A large body of research shows that if your income meets your basic needs, this will make you relatively happy. Curiously, though, if you have more than you need to make ends meet, you won’t (67) be any happier, even if you have a lot more than is necessary.

One of the most intriguing explanations for this (68) is that people often squander their wealth on the very things that are (69) likely to make them feel good, namely, consumer goods. Furthermore, the more they indulge in consumer goods, the more likely they are to obsess (70)

money and the less inclined they will be to use that money to help others. And it is doing just

(71) – using money to help others – that three Canadian researchers, Elizabeth Dunn, Lara Aknin and Michael Norton set out to prove was the key to happiness.

The researchers started out by (72) selecting a group of just over 600 people from the local telephone directory. They asked them four questions: How much do you earn? How happy are you? How much of your income is devoted to personal spending on bills and expenses of gifts for yourself? And how much (73) ‘social spending’, that is, gifts for others and donations to charity? They then looked at the relationship between income, happiness and the two (74) of spending. Unfortunately, the researchers couldn’t claim that it was the type of spending that made people happy or not, though their study did show that spending seems to have more to do with happiness than (75)

alone.

66. A. huge B. limited C. increased D. minority

67. A. importantly B. especially C. necessarily D. regularly

73. A. ends in B. counts on C. adds up D. goes on

74. A. types B. factors C. components D. parts

75. A. consumption B. capital C. income D. expense

Part 2. For questions 76-85, fill each of the blanks with ONE suitable word. Write your answers in the corresponding numbered boxes on your answer sheet. (15 points)

There may be nothing worse than slammed doors, raised voices and tears but, according to new research, it’s actually a good idea for parents who want to be (76) to their teenage children to have a row a day.   (77) of causing alienation, conflict can strengthen parent-adolescent relationships, says Tabitha Holmes, a specialist in adolescent development. “It was a complete surprise to me to (78) during my research that teenagers themselves saw heated arguments as something that brought them closer to their parents,” said Holmes. “While their parents talked about

(79) upsetting arguing with their child was, the adolescents were able to see how locking horns helped them to understand their parents’ view more clearly. They were also very aware that a good row forced them to (80) through, articulate and defend their opinions.”

According to Holmes, it is the day-to-day conflicts - the very ones that can be so draining - that are most constructive: the endless rows (81) homework, clothes, curfews and friends. It’s vital for conflicts to be heated: calm discussion or animated debate does not count. “Adolescents said they only told their mothers what they really felt and thought when they (82) forced to defend their position. If your teenager is rowing with you, it’s actually a (83) of respect,” Holmes said. “It shows they value you enough to tell you their genuine feelings and thoughts. To be positive, (84)

have to be handled in the right way”, Holmes admitted. Parents need to listen genuinely to their teenager's viewpoint; it’s necessary for them to be able to modify their own position in the light of what their child tells them; and they need to be respectful, to (85) into the row acknowledging that their child’s view is worthwhile.

Part 3. For questions 86-95, read the following passage and circle the best answer to each of the following questions. Write your answers in corresponding numbered boxes provided. (15 points)

Demographic Transition

Historically, as countries have developed industrially, they have undergone declines in death rates followed by declines in birth rates. Over time they have tended to move from rapid increases in population to slower increases, then to zero growth and finally to population decreases. The model which demographers use to help explain these changes in population growth is known as the demographic transition model. In order to properly appreciate the demographic transition model, it is necessary to understand two basic concepts: the crude birth rate (CBR) and the crude death rate (CDR). The CBR is determined by taking the number of births in a country in a given year and dividing it by the total population of the country and then multiplying the answer by one thousand. So, for example, the CBR of the United States in 2004 was 14 (in other words, there were 14 births per thousand living people in that year). CDR is worked out in a similar way. The CDR for the United States in 2004 was 8 per thousand.

The first stage of the demographic transition model portrays a preindustrial era when both the birth rate and the death rate were high. Typically, women gave birth to a large number of babies. This


was partly due to cultural and religious pressures but also because families required a large number of children, since often many didn't survive into adulthood due to the harsh living conditions. Furthermore, children were needed to help adults work the land or perform other chores. The death rate was high due to the high incidence of diseases and famine and also because of poor hygiene. Total population tended to fluctuate due to occasional epidemics, but overall there was only a very gradual long-term increase during this stage.

During the second stage, improvements in hygiene, medical care, and food production led to a decrease in the death rate in newly industrializing regions of Western Europe. However, birth rates remained high due to tradition and because many people were involved in agrarian occupations. The combination of a lowered CDR and a stable CBR led to dramatic increases in population starting at the beginning of the nineteenth century.

In stage three, birth rates also began to fall. [A] In cities there was less incentive to produce large numbers of children, since city dwellers no longer worked the land, and the cost of raising children in an urban environment was greater than in rural districts. [B] Furthermore, more children survived into adulthood due to improved living conditions. [C] These economic pressures led to a lower CBR and over time the numbers of people being born started to approximate the numbers dying.

[D] The final stage, which some demographers have called the postindustrial stage, occurs when birth rates and death rates are about equal. In this case there is zero natural population growth. Over time the birth rate may fall below the death rate, and without immigration the total population may slowly decrease. By the early twenty-first century, several European countries were experiencing population declines due to the CDR outstripping the CBR. For example, in Italy in 2004 there were about 9 births per thousand against 10 deaths per thousand.

The getaway blues

A. With so much to do, going on holiday is certainly no vacation. First there’s the flight to arrange, then the hotel or villa to book, and that’s before you’ve sorted out the delicate matter of the beach outfit, evening wear and reading material.

B. For much of the year we fantasize about a long break from the relentless drive of the everyday grind. But making our dream holiday a reality is what makes the stress really kick in, so it is little wonder it takes most holidaymakers a good few days to relax after their arrival. No matter how idyllic the surroundings, there’s no immediate way to simply forget all about work, the children’s schooling, the leaking roof and all those other domestic issues we long to escape.

C. Susan Quilliam, psychologist, body language expert, and regular TV and radio commentator, states that stress creates actual changes in the body’s hormonal balance, which in turn leads to a changed psychological state. She continues by pointing out that stress caused by trying to arrange a holiday can be responsible for these hormonal changes in the body and that this can lead to dramatic mood alteration. These changes in mood can range from anxiety and irritability to a range of more serious psychological problems including mild depression.

D. As if that weren’t bad enough, Ms. Quilliam goes on to say that these hormonal changes do not rectify themselves immediately when the stressful situation is removed. It can take the body a certain amount of time to regain its hormonal balance and for the individual to become relaxed again. That is why if we get stressed before the holiday, we may not be able to relax sufficiently to enjoy ourselves – often for several days after our arrival. We can be lying on a beach in the sunshine, but feeling stressed!

E. So how many days of our holiday are going to be wasted recovering from going on holiday? Is it worth going on holiday at all? To answer these questions we now have a formula to calculate the amount of holiday time needed to recover from the stress of preparing for what should be our annual


period of rest and recuperation. The formula, devised by Ms. Quilliam, is calculated thus: time spent preparing for the holiday, multiplied by the level of stress caused by the preparation (on a scale of 0 to 9), then divided by the stress level of the holiday (on a scale of 1 to 15). The result is the number of recovery hours needed before relaxation is possible.

F. Ms. Quilliam points out that today’s pressurized lifestyles mean that going on holiday is a lot more stressful. Taking a holiday is no longer a question of catching a bus to the nearest seaside resort with your bucket and spade. We not only have to organize foreign travel and negotiate long, complex journeys, we also have to settle our home and work matters before we go. Add in potential tension with travel partners and the psychological pressures of high expectations, and by the time we arrive at our destination, we’re stressed to the max!

G. So according to Ms. Quilliam, the secret to a stress-free holiday is planning, choosing the right kind of holiday and having realistic expectations. This means concluding any unfinished work in the office and ensuring the little ones are sufficiently entertained during the trip. You must prepare and plan well in advance, don’t leave things to the last minute, make a list of the things that you need to do, and cross them off one by one. If you feel it’s all too much, then book an all-inclusive holiday where you are transferred to the hotel, you don’t have to negotiate lots of different restaurants with the children, and you have a travel rep on hand to help you with any problems.

H. The results of a survey commissioned by Lloyds TSB bank and carried out by Ms. Quilliam have confirmed her theories; today’s holidaymakers really are stressed out. More than 83 percent of people surveyed admitted to getting ‘severely stressed’ in the run-up to their holiday. More than a quarter of people admitted to needing the first few days of their holiday to recover. Some became so anxious they left without making essential arrangements and forgot things such as feeding the cat (11 per cent), taking out travel insurance (20 per cent), and cancelling the milk (12 per cent). Amazingly, a tiny minority of travellers (a little over 1 per cent) actually forgot to tell their bosses they were going on holiday!

A leading psychologist has invented a simple (102) to work out the number of hours required at the beginning of a holiday to get over the stress of all the preparation before departure. The problem is that taking a holiday these days is much more of a stressful experience than it was in the past as a result of our (103)       _ . However, stress levels can be decreased by having realistic expectations of the holiday and making sure you complete all the work before leaving.
