You feel generally depressed and unable to concentrate. Your pattern of daily activity may change：you find yourself awake and active in the middle of the night；you sleep late into the day. You stay in your room and have little contact with people except with those who speak your language. In your mind，you criticize the people around you；You are constantly comparing between life here and the perfect life back home. Above a11, you are homesick almost all the time.
If you ever find yourself behaving in these ways，you are probably suffering from culture shock. Culture shock is a psychological condition that sometimes has physical effects. It affects people who have moved away from an environment where they know how to live into a new environment where much is unfamiliar to them-the food，the weather, the language，and especially the unwritten rules for social behavior.
Culture shock is caused. therefore，by a lack of familiarity with the system of rules that the new society uses for everyday living. Language is an obvious example of one type of these rules. If your language is limited，even the simplest task can suddenly become difficult for you. However, knowledge of the language doesn’t make you free from the effects of culture shock as many Britons in the United States and many Americans in Britain will experience. Most people are unaware that each culture has its own rules for social behavior；they certainly think that polite， civilized people behave the same way worldwide. This mistaken belief will cause you to behave and judge the behavior of others according to the rules you learned as a member of your own culture. If the rules are different, then people will misunderstand your behavior, and you will misunderstand theirs.
How can you deal with culture shock? First, you need to realize that every newcomer suffers from some culture shock. You’re not the only case. Second，remember that culture shock can be cured. The process of recovery will start as you begin to become used to the new culture. Of course learning the language will help remove the obstacles to communication and will ease the job of making Mends with people. Recognizing and learning the new cultural rules of behavior, however, may be just as important. You’ll still have emotional reactions to unfamiliar situations but you’11 find yourself making jokes about them rather than condemning the entire society as “stupid.” The jokes are a good sign：they show that you are recovering.What’s the main idea of the first paragraph?

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.

Directions: Read the following passage. Answer the questions according to the information given in the passage.
Kids and Ponds
Years ago there was a group of kids who would hang around at some local ponds in the woods near their houses in Warwick, Rhode Island. In summer they caught frogs and fish. When winter arrived they couldn't wait to go skating. Time passed, and the ponds became the only open space for the kids to enjoy themselves in that neighborhood.
One day. a thirteen-year-old boy from this group of kids read in the local newspaper that a developer wanted to fill in the ponds and build over a hundred small houses called condominiums. So the boy went door to door and gathered more than two hundred signatures (签名）to stop the development A group of citizens met and decided to support him.
At the meeting of the town planning board (委员会)，the boy was quite nervous at first and spoke very softly. But when he saw the faces of his friends and neighbors in the crowd and thought about what was happening to their favorite ponds，his voice grew louder. He told the town officials that they should speak for the citizens. He also insisted that they should leave enough space for children. A few days later，the developer stopped his plan.
Nine years later, when that teen was a senior in college, he was informed that the developer was back with his proposal to build condominiums. Now twenty-two years old, he was studying wetlands ecology. He again appeared before the town planning board. This time as an expert witness, he used environmental protection laws to explain restrictions on development in and around wetlands and the knowledge of wetlands ecology to help improve the development. Finally some condominiums were built, but less than half the number the developer wanted. The ponds where those kids used to hang around were protected by a strip of natural land，and are still there today.

The behaviour of a building’s users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions (排放）by 80 percent by 2050, part of which will be achieved by all new homes being zero-carbon by 2016. But this report shows that sustainable building design on its own — though extremely important- is not enough to achieve such reductions: the behaviour of the people using the building has to change too.
The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency (效率)，which instead focus on architectural and technological developments.
‘Technology is going to assist but it is not going to do everything,’explains Katy Janda, a UKERC senior researcher，‘consumption patterns of building users can defeat the most careful design. ’In other words，old habits die hard, even in the best-designed eco-home.
Another part of the problem is information. Households and bill-payers don’t have the knowledge they need to change their energy-use habits. Without specific information，it’s hard to estimate the costs and benefits of making different choices. Feedback (反馈） facilities, like smart meters and energy monitors，could help bridge this information gap by helping people see how changing their behaviour directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters.
Social science research has added a further dimension (方面），suggesting that individuals’behaviour in the home can be personal and cannot be predicted 一 whether people throw open their windows rather than turn down the thermostat (恒温器) , for example.
Janda argues that education is the key. She calls for a focused programme to teach people about buildings and their own behaviour in them.As to energy use, the new research from UKERC stresses the importance of________.
| A． zero-carbon homes | B．the behaviour of building users |
| C． sustainable building design | D．the reduction of carbon emissions |
The underlined word “which” in Paragraph 2 refers to”________.”
| A．the ways | B．their homes |
| C． developments | D．existing efforts |
What are Katy Janda’s words mainly about?
| A． The importance of changing building users, habits. |
| B． The necessity of making a careful building design. |
| C． The variety of consumption patterns of building users. |
| D． The role of technology in improving energy efficiency. |
The information gap in energy use _______.
| A． can be bridged by feedback facilities |
| B． affects the study on energy monitors |
| C． brings about problems for smart meters |
| D． will be caused by building users’ old habits |
What does the dimension added by social science research suggest?
| A． The social science research is to be furthered. |
| B． The education programme is under discussion. |
| C． The behaviour of building users is unpredictable. |
| D． The behaviour preference of building users is similar. |
In the mid-1950s, I was a somewhat bored early-adolescent male student who believed that doing any more than necessary was wasted effort. One day, this approach threw me into embarrassment
In Mrs. Totten’s eighth-grade math class at Central Avenue School in Anderson, Indiana, we were learning to add and subtract decimals (小数).
Our teacher typically assigned daily homework, which would be recited in class the following day. On most days, our grades were based on our oral answer to homework questions.
Mrs. Totten usually walked up and down the rows of desks requesting answers from student after student in the order the questions had appeared on our homework sheets. She would start either at the front or the back of the classroom and work toward the other end.
Since I was seated near the middle of about 35 students, it was easy to figure out which questions I might have to answer. This particular time, I had completed my usual two or three problems according to my calculations.
What I failed to expect was that several students were absent, which threw off my estimate. As Mrs. Totten made her way from the beginning of the class，I desperately tried to determine which math problem I would get. I tried to work it out before she got to me, but I had brain freeze and couldn’t function.
When Mrs. Totten reached my desk，she asked what answer I’d got for problem No. 14. “I…I didn’t get anything,” I answered，and my face felt warm.
“Correct,” she said.
It turned out that the correct answer was zero.
What did I learn that day? First, always do all your homework. Second, in real life it isn’t always what you say but how you say it that matters. Third，I would never make it as a mathematician.
If I could choose one school day that taught me the most, it would be that one.What does the underlined part in Paragraph 1 indicate?
| A． It is wise to value one’s time. |
| B． It is important to make an effort |
| C． It is right to stick to one’s belief. |
| D． It is enough to do the necessary. |
Usually, Mrs. Totten asked her students to _______.
| A． recite their homework together |
| B． grade their homework themselves |
| C． answer their homework questions orally |
| D． check the answers to their homework questions |
The author could work out which questions to answer since the teacher always _______.
| A． asked questions in a regular way |
| B． walked up and down when asking questions |
| C． chose two or three questions for the students |
| D． requested her students to finish their usual questions |
The author failed to get the questions he had expected because _______.
| A． the class didn’t begin as usual |
| B． several students didn’t come to school |
| C． he didn’t try hard to make his estimate |
| D． Mrs. Totten didn’t start from the back of the class |
Which of the following can be the best title for the passage?
| A． An Unforgettable Teacher |
| B． A Future Mathematician |
| C． An Effective Approach |
| D． A Valuable Lesson |
