Last year, my brother and I went to Miami for a vacation. Some of my friends who had been there before said_1._____ was a wonderful holiday destination. Before we went, we had planned for months. When the day came, we were ready.
After our plane landed, we went to the hotel. We had made our reservation six months__2.__ （early）, but the man at the front desk said there had been a mistake. We 3.__（tell）that our rooms hadn’t been reserved for that week, _4.__ for the week after. I didn’t understand 5. this would happen and my credit card had already been charged__6._ the reservation. What’s worse, the hotel had been fully booked. When we were wondering what to do, the manager came out. She was _7.（surprise）helpful. She apologized for the mistake and gave us a spare VIP room on 8.____ top floor. We had never stayed in such an amazing room, and we weren’t charged extra.
The next day, my brother and I went to the beach9.__ we watched some people play volleyball. We got a little_10.___（sunburn），but the day had been so relaxing that we didn’t mind.
I went to a group activity, “Sensitivity Sunday”, which was to make us more the problems faced by disabled people. We were asked to “ a disability” for several hours one Sunday. Some members, , chose to use wheelchairs. Others wore sound-blocking earplugs（耳塞）or blindfolds（眼罩）.
Just sitting in the wheelchair was a experience. I had never considered before how it would be to use one. As soon as I sat down, my made the chair begin to roll. Its wheels were not . Then I wondered where to put my . It took me quite a while to get the metal footrest into . I took my first uneasy look at what was to be my only means of for several hours. For disabled people, “adopting a wheelchair” is not a temporary（临时的） .
I tried to find a position and thought it might be restful, kind of nice, to be around for a while. Looking around, I I would have to handle the thing myself? My hands started to ache as I the heavy metal wheels. I came to know that controlling the of the wheelchair was not going to be a(n) task.
My wheelchair experiment was soon . It made a deep impression on me. A few hours of “disability” gave me only a taste of the , both physical and mental, that disabled people must overcome.

Business is the organized approach to providing customers with the goods and services they want. The word business also refers to an organization that provides these goods and services. Most businesses seek to make a profit（利润）— that is, they aim to achieve income that is more than the costs of operating the business. 1. Commonly called nonprofits, these organizations are primarily nongovernmental service providers. 2.
Business management is a term used to describe the techniques of planning, direction, and control of the operations of a business. 3. One is the establishment（制定） of broad basic policies with respect to production; sales; the purchase of equipment, materials and supplies; and accounting4. The third relates to the establishment of standards of work in all departments. Direction is concerned primarily with supervision（监管）and guidance by the management in authority. 5.
A. Control includes the use of records and reports to compare actual work with the set standards for work.
B. In this connection there is the difference between top management and operative management.
C. Examples of nonprofit business include such organizations as social service agencies and may hospitals.
D. However, some businesses only seek to earn enough to cover their operating costs.
E. Planning in business management has three main aspects.
F. In the theory of business management, organization has two main aspects.
G.. The second aspect relates to the application of these policies by departments.
Scientists have discovered a special biological behavior in dolphins（海豚） that could lead to a treatment for late-onset diabetes（晚发的糖尿病） in humans. Studies on dolphins found that healthy dolphins switch into a diabetic-like state overnight when they are not feeding, but return to normal when they eat the following morning.
The extraordinary finding has led scientists to suggest that dolphins have “genetic switch” that allows them to imitate diabetes while they are not feeding for a night, without suffering any ill effect.
If researchers can identify a similar genetic pathway in human, they may be able to develop drugs to effectively switch off diabetes. Some 2.2 million people in Britain have type 2 (or late-onset) diabetes, a figure that is expected to reach 4 million by 2025 as a consequence of rising levels of obesity（肥胖）.
The tissues of people with type 2 diabetes have become resistant to insulin（胰岛素）so they lose the ability to control sugar levels in their blood. The condition can damage the heart, eyes, kidneys（肾脏） and nerves and contribute to 5% of all deaths, according to the World Healthy Organisation.
Dolphins appear to imitate diabetes to keep high levels of blood sugar when food is rare. Like humans, dolphins need some sugar in their blood for their brains to function normally. Venn-Watson’s team analysed 1,000 blood samples（样本） from 52 dolphins while they didn’t eat anything overnight and fed in the morning. At night time, the dolphins’ metabolism（新陈代谢）changed greatly and showed similar characteristics to that seen in people with type 2 diabetes.
“It is our hope that this discovery can lead to new ways to prevent, treat and maybe even cure diabetes in humans,” said Stephanie Venn-Watson, director of clinical research at the National Marine Foundation in San Diego.

They baby is just one day old and has not yet left hospital. She is quiet but alert （警觉）. Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze（凝视） starts to lose its focus — until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?
Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise （同样地） when the researchers started with drumbeats and moved to spots.

B. To see how babies recognize sounds.
C. To carry their experiment further.
D. To keep the babies’ interest.
4. Where does this text probably come from?
A. Science fiction. B. Children’s literature.

Some people will do just about anything to save money. And I am one of them. Take my family’s last vacation. It was my six-year-old son’s winter break form school, and we were heading home from Fort Lauderdale after a weeklong trip. The flight was overbooked, and Delta, the airline, offered us $400 per person in credits to give up our seats and leave the next day. I had meetings in New York，So I had to get back. But that didn't mean my husband and my son couldn't stay. I took my nine-month-old and took off for home.
The next day, my husband and son were offered more credits to take an even later flight. Yes, I encouraged—okay, ordered—them to wait it out at the airport, to "earn" more Delta Dollars. Our total take: $1,600. Not bad, huh?
Now some people may think I'm a bad mother and not such a great wife either. But as a big-time bargain hunter, I know the value of a dollar. And these days, a good deal is something few of us can afford to pass up.
I've made living looking for the best deals and exposing （揭露） the worst tricks. I have been the consumer reporter of NBC's Today show for over a decade. I have written a couple of books including one titled Tricks of the Trade: A Consumer Survival Guide. And I really do what I believe in.
I tell you this because there is no shame in getting your money’s worth. I’m also tightfisted when it comes to shoes, clothes for my children, and expensive restaurants. But I wouldn't hesitate to spend on a good haircut. It keeps its shape longer, and it's the first thing people notice. And I will also spend on a classic piece of furniture. Quality lasts.
