M: I really don’t know what to do this summer. I can’t afford to just sit around, and there don’t seem to be any jobs available.W: Why don’t you try house-sitting Last summer my friend Sally house-sat for the Gammons when they went away on vacation. Mrs. Gammon hired Sally to stay in their house because she didn’t want it left empty.M: You mean the Gammons paid Sally just to live in their houseW: It wasn’t easy. She had to mow the lawn and water the houseplants. And when Jodi house-sat for Mr. Johnson, he had to take care of his pets.M: House-sitting sounds like a good job. I guess it’s a little like baby-sitting-except you’re taking care of a house instead of children.W: The student employment office still has a few jobs posted.M: Do I just have to fill out an applicationW: Sally and Jodi had to interview with the homeowners and provided three references each.M: That seems like a lot of trouble for a summer job.W: Well, the homeowners want some guarantee so that they can trust the house-sitter. You know, they want to make sure you’re not the type who’ll throw wild parties in their house, or move a group of friends in with you.M: House-sitters who do that sort of thing probably aren’t paid then.W: Usually they’re paid anyway just because the homeowners don’t want to make a fuss. But if the homeowner reported it, then the house-sitter wouldn’t be able to get another job. So if the homeowner reported it, then the house-sitter wouldn’t be able to get another job. So why don’t you applyM: Yeah, I think I will. Which job does the woman suggest to the man().
W: Dr. Huber, when did you first become interested in physics and musicM: I can’t remember a time when I wasn’t interested in physics. When I was a child, I was very curious about the world around me. For example, I always wondered why light behaves the way it does. I found it more fun to play with a prism than to play with the kids in the neighborhood. I wasn’t very social, but I was really into figuring out how things worked. I got my own telescope when I was eight years old, and I loved to take it out at night and go star gazing. I would look at the planets and stars and wonder what was out there. When I was ten, my father bought me a book on the universe, and I just ate it up. In fact, I still have that book right here in my office.It was the same with music. I’ve always had a natural ear for music, perfect pitch. Even as a young child, if I heard a song on the radio, I could go right to the piano and play it. When I heard a sound like the ring of a telephone, I could identify its pitch and play the note on the piano. However, I didn’t develop a serious interest in becoming a pianist until I was in college. I also seemed to do well in school in the visual arts like painting and drawing.W: What commonality do you see between music and physicsM: There is a common misconception that art and science are completely separated from each other. I think the distinction is artificial. In reality, art and science are not as mutually exclusive as one might assume. Solving a complicated mathematical problem, for example, can require the same degree of creative thinking as painting a landscape or writing a poem. I feel an indefinable tingle when I play the Schumann Concerto or dance the pas de deux from Romeo and Juliet. I get that the same tingle from theoretical physics.The beauty of art is readily apparent to most people. However, in the case of theoretical physics, the beauty is not nearly as accessible to the general public, but it is every bit as exciting. Nature seems to follow certain principles, very much the same as art does.It’s not uncommon for physicists to become accomplished musicians. Music theory is a very mathematical discipline. Relationships among various notes in classical harmony are based on simple mathematical relationships.W: You have said that physics is beautiful. What makes it beautiful to youM: To me, it’s incredible the way nature seems to work so perfectly. I think it is beautiful. I always tell my students on the first day of class. "If you like reading Sherlock Holmes detective stories, you’ll like doing physics problems. " Physics is about figuring things out—discovering how they work, just like a detective.A lot of people fear physics because they view it as a big complicated jumble of facts that have to be memorized. But that’s not true. It’s an understanding of how nature works, how the various parts interact. One can view art and literature as the relationships and interactions of ideas. In the same way, physics studies the relationships and interactions of concepts. In other words, to me art and science fundamentally attempt to achieve the same objective—understanding of the world around us!The whole universe seems to follow some very basic principles as it evolves in with time, some of these principles including the Conservation of Energy and the Conservation of Angular Momentum. The conservation laws of physics are like non-interest bearing checking accounts. In the case of energy conservation, you can make energy deposits and energy withdrawals, but all the energy is accounted for.The rotation of objects is governed by a law called the Conservation of Angular Momentum, which applies to everything in the universe including the rotation of stars, the rotation of the planets and their orbits, the behavior of an electron in an atom, the spin of a figure skater, and the rotation of wheels on a truck. What it all comes down to in the end is that everything in the universe fits together like the pieces of a perfect puzzle. As Einstein said, "The most incomprehensible thing about the universe is that it is comprehensible. \ When did Dr. Huber get his own telescope
Not long ago, a mysterious Christmas card dropped through our mail slot. The envelope was addressed to a man named Raoul, who, I was relatively certain, did not live with us. The envelope wasn’t sealed, so I opened it. The inside of the card was blank. Ed, my husband, explained that the card was both from and to the newspaper deliveryman. His name was apparently Raoul, and Raoul wanted a holiday tip. We were meant to put a check inside the card and then drop the envelope in the mail. When your services are rendered at 4 a.m. , you can’t simply hang around, like a hotel bellboy expecting a tip. You have to be direct.So I wrote a nice holiday greeting to this man who, in my imagination, fires The New York Times from his bike aimed at our front door, causing more noise with mere newsprint than most people manage with sophisticated black market fireworks.With a start, I realized that perhaps the reason for the 4 a.m.—wake-up noise was not ordinary rudeness but carefully executed spite: I had not tipped Raoul in Christmases past. I honestly hadn’t realized I was supposed to. This was the first time he’d used the card tactic. So I got out my checkbook. Somewhere along the line, holiday tipping went from an optional thank-you for a year of services to a Mafia-style protection racket (收取保护费的黑社会组织).Several days later, I was bringing our garbage bins back from the curb when I noticed an envelope taped to one of the lids. The outside of the envelope said MICKEY. It had to be another tip request, this time from our garbage collector. Unlike Raoul, Mickey hadn’t enclosed his own Christmas card from me. In a way, I appreciated the directness. "I know you don’t care how merry my Christmas is, and that’s fine, " the gesture said. "I want $30, or I’ll ’forget’to empty your garbage bin some hot summer day. "I put a check in the envelope and taped it back to the bin. The next morning, Ed noticed that the envelope was gone, though the trash hadn’t yet been picked up: "Someone stole Mickey’s tip! " Ed was quite certain. He made me call the bank and cancel the check.But Ed had been wrong. Two weeks later, Mickey left a letter from the bank on our steps. The letter informed Mickey that the check, which he had tried to cash, had been cancelled. The following Tuesday morning, when Ed saw a truck outside, he ran out with his wallet. "Are you Mickey"The man looked at him with scorn. "Mickey is the garbageman. I am the recycling. " Not only had Ed insulted this man by hinting that he was a garbageman, but he had obviously neglected to tip him. Ed ran back inside for more funds. Then he noticed that the driver of the truck had been watching the whole transaction. He peeled off another twenty and looked around, waving bills in the air. "Anyone else"Had we consulted the website of the Emily Post Institute, this embarrassing breach of etiquette (礼节) could have been avoided. Under "trash/recycling collectors" in the institute’s Holiday Tipping Guidelines, it says, "$10 to $30 each. " You may or may not wish to know that your pet groomer, hairdresser, mailman and UPS guy all expect a holiday tip. The newspaper deliveryman put a blank card inside the envelope because ().
Questions 14～16 are based on the following conversation. You now have 15 seconds to read Questions 14～16.M: Did you hear about the air crash that occurred in South America recently It was quite a tragic accident!W: No, I didn’t see anything in the news about it. What happenedM: A foreign airliner was attempting to land at night in a mountainous area in Argentina and flew into a hill!W: That sounds really terrible! Did anyone surviveM: No, everyone aboard, including the crew, was killed instantly.W: What were the circumstances Were they bad weather, a fire, or engine failureM: Apparently, there were some low clouds in the area, but mostly it was just miscommunication between the pilots and the air traffic controllers.W: Weren’t they both speaking in English, the official international aviation languageM: Yes they were, but the transition from poor quality radios was slightly distorted and the accents of the Spanish speaking controllers was so strong that the pilots misunderstood a vital instruction.W: How could a misunderstanding like that cause such a serious accidentM: The pilots were told to descend to 22,000 feet. The instruction actually meant 22,000 feet, but they thought they heard descend 2,000 feet. That’s a huge difference, and it should have been confirmed, but it was not. Unfortunately, the terrain of the mountains in Norweija ascend to 2,000 feet.W: So the pilots did descend to the wrong altitude then, because they were following the air controller’s instructions.M: Sadly enough, yes they did. It was a really bad mistake. Many people died as a result of the simply misunderstanding.W: Wow, that’s a powerful lesson on how important it can be to accurately communicate with each other. What lesson could be drawn from the accident().
