Unless we spend money to spot and prevent asteroids (小行星) now, one might crash into Earth and destroy life as we know it, say some scientists. Asteroids are bigger versions of the meteoroids (流星) that race across the night sky. Most orbit the sun far from Earth and don’’t threaten us. But there are also thousands of asteroids whose orbits put them on a collision course with Earth. Buy $ 50 million worth of new telescopes right now. then spend $ 10 million a year for the next 25 years to locate most of the space rocks. By the time we spot a fatal one, the scientists say, we’’ll have a way to change its course. Some scientists favor pushing asteroids off course with nuclear weapons. But the cost wouldn’’t be cheap. Is it worth it Two things experts consider when judging any risk are: 1) How likely the event is; and 2) How bad the consequences if the event occurs. Experts think an asteroid big enough to destroy lots of life might strike Earth once every 500,000 years. Sounds pretty rare — but if one did fall, it would be the end of the world. "If we don’’t take care of these big asteroids, they’’ll take care of us," says one scientist. "It’’s that simple." The cure, though, might be worse than the disease. Do we really want fleets of nuclear weapons sitting around on Earth "The world has less to fear from doomsday (毁灭性的) rocks than from a great nuclear fleet set against them," said a New York Times article. Which of the following best describes the author’’s tone in this passage

An auto loan John Baker works in the loan department of a bank in Denver, Colorado. He is a loan of- ricer. Stanley Fanelli has an appointment with him now to ask about a loan. He needs money to buy a new car. Mr. B: Hello, Mr. Fanelli. Please have a seat. What can I do for you today Mr. F: I want to borrow some money to buy a car. A friend of mine, Jack Richardson, bought a new car last week. He told me that he got his loan here. Mr. B: Oh yes. I remember him. I was the loan officer who spoke with him. Mr. F: He said that you were very helpful. I know very little about loans and I hope you can explain things to me. Mr. B: I will certainly try. What questions did you have for me Mr. F: First, I want to know if loans for buying cars are commercial loans or personal loans. Mr. B: Neither, Mr. Fanelli. They’re auto loans. A commercial loan is principal that banks lend to businesses. Personal loans are made to individuals, but not for buying cars. Mr. F: What about interest rates Mr. B: The rate of interest currently in effect on auto loans is 16%. Mr. F: For how long will I have to make monthly payments Mr. B: The term of the loan is three years, so there will be 36 monthly payments. Mr. F: Do I have to give the bank any collateral Mr. B: The car serves as collateral. If you default, the bank can take possession of the car. The bank also checks your credit file to make sure that you always paid back your loans in the past. Do you have any charge accounts Mr. F: My wife and I bought our furniture with our charge card and we even used it to buy airplane tickets for our vacation in California last year. We paid off both those debts promptly. Mr. B: That’s very good. I assume there will be no problem. But the first thing you have to do is fill out this loan application. Mr. F: Thank you very much. I’ll start right now. State whether each statement is true or false based on the dialogue between John Baker and Stanley Fanelli. Mr. Fanelli doesn’t have any charge accounts.
Can animals have a sense of humor Sally Blanchard, publisher of a newsletter called the Pet Bird Report, thinks a pet parrot may have pulled her leg. That’s one explanation for the time her African gray parrot, named Bongo Marie, seemed to feign distress at the possible death of an Amazon parrot named Paco. It happened one day when Blanchard was making Cornish game hen for dinner. As Blanchard lifted her knife, the African gray threw back its head and said, "Oh, no! Paco!" Trying not to laugh, Blanchard said, "That’s not Paco," and showed Bongo Marie that the Amazon was alive and well. Mimicking a disappointed tone, Bongo Marie said, "Oh, no," and launched into a hoarse laugh. Was the parrot joking when it seemed to believe the other bird was a goner Did Bongo Marie comprehend Blanchard’s response Studies of African grays have shown that they can understand the meaning of words--for example, that red refers to a color, not just a particular red object. Parrots also enjoy getting a reaction out of humans, and so, whether or not Bongo Marie’s crocodile tears were intentional, the episode was thoroughly satisfying from the parrot’s point of view. When Blanchard was making Cornish game hen for dinner, Bongo Marie acted as if Paco was ______.
