Choosing the Right Resolution (决定)
Millions of Americans began 2014 with the same resolution they started 2013 with, a goal of losing weight. However, setting weight loss as a goal is a mistake.
To reach our goal of losing weight --- the output, we need to control what we eat --- the input ( 输入). That is, we tend to care about the output but not to control the input. This is a bad way to construce goals. The alternative is to focus your resolution on the input. Instead of resolving to lose weight, try an actionable resolution: “I’ll stop having desert for lunch,” or “I’ll walk every day for 20 minutes.” Creating a goal that focuses on a well-specified input will likely be more effective than concentrating on the outcome.
Recently a new science behind incentives (激励) , including in education, has been discussed. For example, researcher Roland Fryer wanted to see what works best in motivating children to do better in school. In some cases, he gave students incentives based on input, like reading certain books, while in others, the incentives were based on output, like results on exams. His main finding was that incentives increased achievement when based on input but had no effect on output. Fryer’s conclusion was that the intensives for inputs might be more effective because do not knoe how to do better on exam, aside from general rules like “study harder.” Reading certain books, on the other hand, is a well-set task over which they have much more control.
As long as you have direct control over your goal, you have a much higher chance of success. And it’s easier to start again if you fail, because you know exactly what you need to do.
If you want to cut down on your spending, a good goal would be making morning coffee at home instead of going to a cafe, for example. This is a well-specified action-based goal for which you can measure your success easily. Spending less money isn’t a goal because it’s too general. Similarly, if you want to spend more time with your family, don’t stop with this general wish. Think about an actionable habit that you could adopt and stick to, like a family movie night every Wednesday.
In the long run, these new goals could become a habit.

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. 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.
B. Opportunities you give up for better ones.

D. Opportunities you make up for.
