Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure (血压) and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer.

     Any owner will tall you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress (紧张) levels and blood pressure in people - half of them pet owners –while they performed 5 minutes of mental arithmetic (算术) or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did it best. Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates. With pets in the room, people also made fewer math mistakes than when doing in front of other companions. It seems people feel more relaxed (放松)around pets, says Allen, who thinks it may be because pets don't judge.

     A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs; a separate group of 56 people without pets were put on a diet program. On average, people lost about I1 pounds, or 5% of their body weight. Their dogs did even better, losing an average of 12 pounds, more than 15% of their body weight. Dog owners didn't lose any more weight than those without dogs but, say researchers, got more exercise overall-mostly with their dogs - and found it worth doing.

Many of us assume that with such a last name, Peter Buffett, 52, must enjoy a life of endless privilege. But the son of billionaire investor (投资人) Warren Buffett definitely doesn’t think so.

   “People who are born with a silver spoon in their mouth can fall victim (受害者) to what my father has called a silver dagger (匕首) in your back,” Buffett told Reuters in an interview. “It leads to a sense of entitlement (特权) and a lack of personal achievement.”

  Entitlement, he believes, is the worst thing ever. “Anybody who acts like they deserve (应得) something ‘just because’ is a disaster,” he said.

  In his new book, Life Is What You Make It: Finding Your Own Path to Fulfillment, Buffett says that the only real inheritance (遗产) handed down from his parents was a philosophy (价值观): Forge your own path in life. It is a belief that has allowed him to follow his own passions, establish his own identity, and reap (收获) his own successes.

  Did his father ever want him to go into finance? “It was encouraged for a moment when I was open to the idea,” he told Reuters. But as he grew older, it became clear the financial world “was not speaking to my heart.”

   His father accepted his choice to become a musician. He began his musical career by writing music for TV commercials (广告). He then released his own albums.

   “I am my own person and I know what I have accomplished in my life,” he told Reuters. “This isn’t about wealth or fame or money or any of that stuff, it is actually about values and what you enjoy and finding something you love doing.”

   Along with the book, Buffett has begun a “Concert & Conversation” tour in which he plays the piano, talks about his life and warns against consumerist (消费主义) culture and damaging the environment.

   “Economic prosperity (繁荣) may come and go; that’s just how it is,” he writes in the book. “But values are the steady currency (硬通货) that earn us the all-important rewards.”

What does “It” in the second paragraph refer to?

  A. A life of a top investor.          B. A silver spoon in the mouth.

  C. Being born to a wealthy family.  D. The victim of a silver dagger in the back.

What does the article tell us?

  A. Peter Buffett is a born musician.

  B. Peter Buffett enjoys a hugely privileged life.

  C. A wealthy family can benefit a child but also spoil him or her.

  D. Peter Buffett was forced by his parents to take over their business.

The article claims that Peter Buffett owes his achievements largely to ______.

  A. his passion for music      B. the good education he received

  C. his great determination        D. the values he learned from his parents

Which of the following statements would Peter Buffett probably agree to?

  A. Wealth is there to enjoy to the fullest.

  B. A person’s value lies within.

  C. Many people are fooled by economic prosperity.

  D. Young people should choose their own philosophy, whatever their parents believe in.

【小题1】What does the text mainly discuss?

Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country’s economy. It is important to think about the people and a destination country and how tourism affects them. Tourism should help a country keep the customs and beauty that attracts the tourists. Tourism should also advance the wealth and happiness of local inhabitants.
Too much tourism can be a problem. If tourism grows too quickly, people must have other jobs to work in the tourism industry. This means that other parts of the country’s economy can suffer.
On the other hand, if there is not enough tourism, people can lose jobs. Business can also lose money. It costs a great deal of money to build large hotels, airports, air terminals, first-class roads, and other support facilities (配套设施) needed by tourist attractions. For example, a major international-class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel lose money.
Building a hotel is just a beginning. There must be many support facilities as well, including roads to get to the hotel, electricity, sewers to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, job and money are lost.
