However wealthy we may be, we can never find enough hours in the day to do everything we want. Economics deals with this problem through the concept of opportunity cost, which simply refers to whether someone’s time or money could be better spent on something else.
Every hour of our time has a value. For every hour we work at one job we could quite easily be doing another, or be sleeping or watching a film. Each of these options has a different opportunity cost—namely, what they cost us in missed opportunities.
Say you intend to watch a football match but the tickets are expensive and it will take you a couple of hours to get to and from the stadium. Why not, you might reason, watch the game from home and use the leftover money and time to have dinner with friends? This—the alternative use of your cash and time—is the opportunity cost.
For economists, every decision is made by knowledge of what one must forgo—in terms of money and enjoyment—in order to take it up. By knowing precisely what you are receiving and what you are missing out on, you ought to be able to make better-informed, more reasonable decisions. Consider that most famous economic rule of all: there’s no such thing as a free lunch. Even if someone offers to take you out to lunch for free, the time you will spend in the restaurant still costs you something in terms of forgone opportunities.
Some people find the idea of opportunity cost extremely discouraging: imagine spending your entire life calculating whether your time would be better spent elsewhere doing something more profitable or enjoyable. Yet, in a sense it’s human nature to do precisely that—we assess the advantages and disadvantages of decisions all the time.
In the business world, a popular phrase is “value for money.” People want their cash to go as far as possible. However, another is fast obtaining an advantage: “value for time.” The biggest restriction on our resources is the number of hours we can devote to something, so we look to maximize the return we get on our investment of time. By reading this passage you are giving over a bit of your time which could be spent doing other activities, such as sleeping and eating. In return, however, this passage will help you to think like an economist, closely considering the opportunity cost of each of your decisions.
小題1:According to the passage, the concept of “opportunity cost” is applied to ________.
A.making more money
B.taking more opportunities
C.reducing missed opportunities
D.weighing the choice of opportunities
小題2:The “l(fā)eftover ... time” in Paragraph 3 probably refers to the time ________.
A.spared for watching the match at home
B.taken to have dinner with friends
C.spent on the way to and from the match
D.saved from not going to watch the match
小題3:What are forgone opportunities?
A.Opportunities you forget in decision-making.
B.Opportunities you give up for better ones.
C.Opportunities you miss accidentally.
D.Opportunities you make up for.

小題1:D  
小題2:C
小題3:B

試題分析:文章大意:本文是一篇議論文。文章論述了不管我們多么的富有,在一天里我們不可能找到足夠的時間做我們想要做的一切。因此,我們要放棄一些事情選擇做更好的事情。
小題1:D考查推理判斷。根據(jù)文章第二、三段,尤其第三段最后一句This—the alternative use of your cash and time—is the opportunity cost可知“機(jī)會成本”這個概念應(yīng)用于衡量機(jī)會的選擇方面。故D正確。
小題2:C考查詞義推測。題中“l(fā)eftover money and time”是指“剩下來的錢和時間”。根據(jù)文章第三段第一句Say you intend to watch a football match but the tickets are expensive and it will take you a couple of hours to get  to and from the stadium.可知leftover … time所指的是“花在觀看比賽(路上)來去的時間”。故C正確。
小題3:B考查推理判斷。根據(jù)文章第四段,尤其最后一句Even if someone offers to take you out to lunch for free, the time you will spend in the restaurant still costs you something in terms of forgone opportunities.可以推測出forgone opportunities是指“所放棄用于更好的機(jī)會”。故B正確。

In real life, the daily struggles between parents and children are around these narrow problems of an extra hour, extra TV show, and so on” said Avi Sadeh, psychology professor at Tel Aviv University. “Too little sleep and more accidents,” he said.
Sadeh and his colleagues found an extra hour of sleep can make a big difference. The children who slept longer, although they woke up more frequently during the night, scored higher on tests, Sadeh reported in the March/April issue of journal Child Development.
“When the children slept longer, their sleep quality was somewhat weak, but in spite of this their performance for study improved because the extra sleep was more significant than the reduction in sleep quality. ” Sadeh said. “Some studies suggested that lack of sleep as a child affects development into adulthood and it’s more likely to develop their attention disorder when they grow older. ”
In earlier studies, Sadeh’s team found that fourth graders slept an average of 8. 2 hours and sixth graders slept an average of 7. 7 hours.
“Previous research has shown children in elementary school need at least nine hours of sleep a night on a regular basis, said Carl Hunt, director of the National Center on Sleep Disorders Research in Bethesda, and high-school-age children need somewhat less, he said, adding the results of insufficient sleep could be serious.
“A tired child is an accident waiting to happen,” Hunt said. “And as kids get older, toys get bigger and the risks higher. ”Hunt also said too little sleep could result in learning and memory problems and long-term effects on school performance.
“This is an important extension of what we already know, ” Hunt said of Sadeh’s research, adding sleep is as important as nutrition(營養(yǎng)) and exercise to good health.
“To put it into reality,” Hunt said, “parents should make sure they know when their children actually are going to sleep and their rooms are conducive to sleeping instead of playing. ”
小題1:What is Child Development?
A A new story                       B A popular book
C. A periodical magazine               D A TV programme
小題2:How many persons are exactly mentioned in the text?
A One          B Two         C Three           D Four
小題3:The underlined phrase “conducive to” (in the last sentence) means ________.
A helping to happen                 B influenced by
C full of                              D acceptable of
小題4:Which of the following statements is NOT true according to the passage?
A.There are some daily struggles between parents and children because of having nothing in common with extra rest time.
B.The children who sleep longer are weak in their study.
C.Lack of sleep as a child has great effect on their development into adulthood.
D.In general, children in elementary school need at least nine hours of sleep a night.

The Diet Zone: A Dangerous Place
Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically(身體上).
Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤)instead. All we have to do is to swallow or recognize the word “diet” in food labels.
On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.
The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(營養(yǎng)成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.
Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.
51. From Paragraph 1, we learn that ________.
A. diet products fail to bring out people’s potential
B. people have difficulty in choosing diet products
C. diet products are misleading people
D. people are fed up with diet products
52. One psychological effect of diet products is that people tend to _____.
A. try out a variety of diet foods
B. hesitate before they enjoy diet foods
C. pay attention to their own eating habits
D. watch their weight rather than their diet
53. In Paragraph 3, “gain comes without pain” probably means ______.
A. losing weight is effortless
B. it costs a lot to lose weight
C. diet products bring no pain
D. diet products are free from calories
54. Diet products indirectly harm people physically because such products ______.
A. are over-consumed
B. lack basic nutrients
C. are short of chemicals
D. provide too much energy
55. Which of the following shows the structure of the passage?

According to a recent article in The Wall Street Journal, we might all be braggarts(大話王) in this competitive society addicted to social networking.
Take a close look at your social­networking sites. Do you like to post photos of yourself in restaurants to show others what an exciting life you have? Or do you like to write about how happily in love you are? Or perhaps you are of the subtle type who constantly complain about jobs but really just want to impress others with your important position.
According to the results of a series of experiments conducted by Harvard University neuroscientists(神經(jīng)科學(xué)家), the reward areas of our brain——the same areas that respond to “primary rewards” such as food ——are activated when we talk about ourselves. We devote between 30 to 40 percent of our conversation time to doing just that. Unfortunately, Bernstein says, some people can't tell the difference between sharing positive information that others might actually want to know and direct bragging. She suggests that bragging involves comparison, whether stated or implied.
“We are expected to be perfect all the time. The result is that more and more people are carefully managing their online images”. says Elizabeth Bernstein, a columnist with the Wall Street Journal.
But the issue is not limited to the Internet. In a fiercely competitive job market we must sell ourselves on multiple platforms and show that we are better than others. In fact, we have become so accustomed to bragging that we don't even realize we are doing it, says Bernstein. This is harmful to our relationships and puts people off.
Bernstein talked to some experts who said that people brag for all sorts of reasons: to appear worthy of attention; to prove to ourselves we are doing fine and that people who said we would fail are wrong; or simply because we're excited when good things happen to us.
“Feel sorry for them, because they're doing this unconscious, destructive thing that won't help them in the long run,” said Professor Simian Valier, a research psychologist at Washington University.
小題1:The underlined word “subtle” in Para.2 is closest in meaning to “________”.
A.hiddenB.a(chǎn)pparent
C.outstandingD.simple
小題2:Which of the following is one of the features of braggarts?
A.They control conversation and only talk about themselves.
B.They know well how to share positive information.
C.They self­promote to stand out in their career.
D.They don't pay much attention to their online image.
小題3:What can we infer from the passage?
A.Braggarts make a good first impression but the effect decreases over time.
B.People who like bragging know what they are doing.
C.Braggarts always adopt comparison directly to show they are excellent.
D.They care much about the feelings of others when talking.

To see the world is one thing;to have someone to share it with is another.Indeed,travel becomes more interesting when you have a travel partner.A travel partner can be a close friend,a family member,a pal you’ve met online,or a business friend.

You can meet a good friend
Having a travel mate is a good way of meeting a new friend or even a lifelong partner.You can never count the number of couples who actually found their way into each other’s heart while traveling together in another country.
You can have someone to watch out for you
