D
Let’s do some sleep math．You lost two hours of sleep every night last week because of a big project due on Friday．On Saturday and Sunday，you slept in，getting four extra hours．On Monday morning，you were feeling so bright—eyed that you only had one cup of coffee，instead of your usual two．But don’t be cheated by your energy．You’re still carrying around a heavy load of sleepiness，or what experts call “sleep debt”一in this case something like six hours，almost a full night’s sleep．
Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get．It’s a shortage that grows every time we skim some extra minutes off our nightly sleep．“People get more sleep debt gradually without being noticed，”says William C．Dement，founder of the Stanford University Sleep Clinic．Studies show that such short term sleep lack leads to a foggy brain，worsened vision，and trouble remembering．Long-term effects include obesity(肥胖)，insulin(胰島素)resistance，and heart disease．A survey by the National Sleep Foundation reports that we’re losing one hour of sleep each night——more than two full weeks of sleep every year．
The good news is that，like all debt，with some work，sleep debt can be repaid．Adding all extra hour or two of sleep a night is the way to catch up．For the long-term lack of sleep， take it easy for a few months to get back into a natural sleep pattern．
Go to bed when you are tired，and allow your body to wake you in the morning(no alarm clock allowed)．You may find yourself catatonic(有緊張癥的)in the beginning of the recovery cycle：expect to have ten hours shut—eye per night；As the days pass，however，the amount of sleeping time will gradually decrease．
So earn back that lost sleep and follow the rules of your innate(固有的)sleep needs. You’ll feel better．“When you put away sleep debt,you become a superman,”says Stanford's Dement，talking about the improved mental and physical capabilities that come with being well rested．
53．If you have short-term sleep lack，you may___________．   
A．put on weight    B．get heart disease  C．hate eating food   D．have a poor sight
54．The example of sleep math is used to show______．
A．in what case you build up a sleep debt
B．in what way you can make up for lack of sleep
C．why you are energetic even without enough sleep

科目：高中英語 來源：2012-2013學(xué)年浙江省嘉興市高三上學(xué)期基礎(chǔ)測試英語試卷（解析版） 題型：閱讀理解

You are careful with your money: you collect all kinds of coupons; look for group-buy deals if you eat out; you don't buy clothes unless in a sale. Does all this make you a wise consumer?

Let's do the math first: you walk into a coffee shop and see two deals for a cup of coffee. The first deal offers 33 percent extra coffee. The second takes 33 percent off the  regular price. What's the better deal? Well, they are about the same, you'd think. And you'd be wrong. The deals appear to be equal, but in fact, they are different. Here's the math: Let's say the standard coffee is 10 yuan and let's divide the amount of coffee into three portions(部分). That makes about 3.3 yuan per portion, The first deal gets you 4 portions for 10 yuan (2.5 yuan per portion) and the second gets you 3 portions of coffee for 6.6 yuan (2.2 yuan per portion) and is therefore a better deal.

In a new study published by the Journal of Marketing, participants were asked the same question, and most of them chose the first deal, the Atlantic website reported. Why? Because getting something extra for free feels better than getting the same for less. The applications of this view into consumer psychology(心理) are huge. Instead of offering direct discounts, shops offer larger sizes or free samples.

According to the study, the reason why these marketing tricks work is that consumers don't really know how much anything should cost, so we rely on parts of our brains that  aren't strictly quantitative.

There are some traps we should be aware of when shopping. First of all, we are heavily influenced by the first number. Suppose you are shopping in Hong Kong. You walk into Hermes, and you see a 100,000 yuan bag. "That's crazy." You shake your head and leave. The next shop is Gucci, a handbag here costs 25,000 yuan. The price is still high, but compared to the 100,000 yuan price tag you just committed to your memory, this is a steal. Stores often use the price difference to set consumers' expectation. zxxk

Another trap we often fall to Is that we are not really sure what things are worth. And so we use clues(暗示) to tell us what we ought to pay for them. US economist Dan Ariely has done an experiment to prove this. According to the Atlantic, Ariely pretended he was giving a lecture on poetry. He told one group of students that the tickets cost money and another group that they would be paid to attend. Then he informed both groups that thelecture was free. The first group was anxious to attend, believing they were getting something of value for free. The second group mostly declined, believing they were being forced to volunteer for the same event without reward.

What's a lecture on poetry by an economist worth? The students had no idea. That's  the point. Do we really know what a shirt is worth ? What about a cup of coffee? What's the worth of a life insurance.policy? Who knows? Most of us don't. As a result, our shopping  brain uses only what is knowable:  visual(祝覺的) clues, invited emotions, comparisons, and  a sense of bargain. We are not stupid. We are just easily influenced.

1.The first paragraph of the passage is intended to      

A．a(chǎn)sk a question                          B．introduce a topic

C．give some examples                     D．describe a phenomenon

2.The writer takes the math for example in Paragraph 2 to show      .          _.

A．consumers usually fall into marketing traps

B．consumers' expectation is difficult to predict

C．consumers' purchasing power is always changing

D．consumers rely on their own judgment when shopping

3.What consumer psychology is mentioned in the passage?

A．The first number has little influence on which item should be bought.

B．Consumers never use visual clues to decide how much should be paid.

C．Getting something extra for free is better than getting the same for less.

D．Consumers never rely on parts of the brains that aren't strictly quantitative.

4.According to the passage, shops use the following tricks to make more profits EXCEPT         .  

A．showing price differences                 B．offering larger sizes

C．providing free samples                   D．giving direct discounts

5.What can we know from US economist Dan Ariely's experiment?

A．Ariely's free lecture enjoyed popularity among students.

B．The students actually didn't know what the lecture was worth.

C．The second group was willing to be volunteers without reward.

D．The first group was eager to find out the value of Ariely's lecture.

Coupons to spend

“How did you spend your coupons?”

On their first day back to school, many students in Hangzhou greeted each other this way.

The coupons referred to the 100 yuan coupons each student received form the city government before the Spring Festival holidays. Over 260,000 primary school and middle school students were given coupons. They could use them in local stores and supermarkets, or to see movies and buy books.

The same coupons have also been given to low income families in Hangzhou. Other cities, including Chengdu and Nanjing, also gave coupons to their citizens. More cities are expected to follow their lead.

Why are local governments doing this?

These programmes are all part of a broader effort in China to increase domestic demand in the face of the global financial crisis.

The crisis has seriously affected China’s exports and investments (投資). Many factories in southern cities have been closed down. Some companies are laying off workers or reducing their pay. The stock market and real estate market have been falling.

In a time of financial crisis, people usually respond by saving money. They are uncertain about the future and are afraid that more difficult times may be ahead. Now many people are choosing not to spend money carelessly. Major chain stores have seen a sharp slowdown in sales, analysts say.

But spending keeps an economy healthy. If people don’t spend, there will be too many products in the market. Then shops will stop buying products from factories. When factories receive no orders, they close down. The workers there accordingly lose their jobs. Also, if people don’t spend, the service industry suffers. The total result is that the whole economy breaks down.

Issuing coupons is a practical and effective way to increase domestic demand in the current situation, said Jiang Zengwei, vice-minister of China’s Ministry of Commerce. Hangzhou reported a rise in customers in local markets during Spring Festival holiday.

However, issuing coupons is only a temporary measure. To increase consumers’ confidence, the government needs to establish a sound secure social system in the long term. When people don’t have to worry about education, health care and their pension, they will be more willing to spend instead of saving.

1.Why are local governments issuing coupons?

A. To increase domestic demand in the face of the global financial crisis.

B. To enable students to use them in local stores and supermarkets, or to see movies and buy books independently.

C. To help those low income families in the global financial crisis.

D. To show the government’s ability to solve economic problems

2.What is NOT the influence that the global financial crisis has brought us?

A. China’s exports and investments have been seriously affected.

B. People begin to spend money without a second thought.

C. Workers are faced with losing jobs and the reduction of the salaries.

D. The active stock market and real estate market have gone. 

3.What can be inferred from the passage?

A. Issuing coupons is a practical and effective way to increase domestic demand in a long term.

B. The total result of saving money is that the whole economy breaks down.

C. The government may carry out new policies to encourage citizens to be willing to spend in the near future.

D. After issuing the coupons, the local markets have seen a rise in customers during Spring Festival holiday.

4.If the government is to print a slogan on the coupons to restore consumers’ confidence, what might be used to promote the idea?

A. Spend now, save later.

B. Spend money like there’s no tomorrow; come on!

C. Spend money like it’s going out of style; let’s do it!

D. Big spender, wise spender.
