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 readmg 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.
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
2.Hie "leftover ... 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
3.What are forgone opportunities?
A. Opportunities you forget in decision-making.

How Can I Fight Laziness?
Lazy people will never gain anything in life. However, laziness can be defeated once a few changes have been made in your mind.
1.Many people lack sleep constantly, since they stay up too late and get up too early to prepare for work. These people have little motivation once they arrive home. Laziness works hand in hand with a lack of motivation and a tendency to put off things. By adjusting your sleep schedule to provide a few more hours of meaningful rest, you can fight laziness throughout the day.
Another way to fight laziness is to change your mind from passive to active. Some people treat their lives as if they were pushed from task to task. Others take a more positive approach, viewing each task as a challenge they must overcome alone.2.
Some people fight laziness by removing the temptations(诱惑) that surround them. A television in the living room may provide entertainment, but watching too much TV often contributes to laziness. 3. Complete a few tasks and reward yourself with what you enjoy, such as a good dinner or a film.
Laziness can also be a lasting problem at home. Couples and children may all have different energy levels, but laziness can be spread if not dealt with immediately.4.Be the first to collect and wash dishes after a meal. Others in the home may eventually follow your example and perform their own task. It is difficult to practice laziness when you are surrounded by motivated people.
5.Enough exercise and a balanced diet can help you to develop a healthy lifestyle, thus enabling you to have more energy and help lift your spirits.
A. To fight family laziness, set an example.
B. Knowing how to fight laziness is important.
C. One way to fight laziness is to get enough sleep.
D. Finally, taking exercise regularly can help you fight laziness.
E. With strong determination, you will be able to achieve your goal.
F. Laziness appears when you no longer feel in charge of your own mind.
G. Create a reward system for yourself, just as parents do for a child.
