I can't believe he could jump ____ high.

According to recent surveys, 72% of all Americans believe that the United States government is (1) ____ information about UFOs. Almost 68% of people think that the government has secret knowledge of extraterrestrial life. It is not (2) ___ (surprise) that the government has come under more and more (3) ____ to declassify its UFO records and make them public. A variety of different groups have been involved in these efforts. One group to become involved is called CFI, the Coalition for Freedom of Information, John Podesta, who was White House Chief of Staff during Bill Clinton’s (4) ____(president), is one of the many high-powered people active in this group. CFI’s aim is not to prove the (5) ____(exist) of extraterrestrial life, but to make it easier for scientists in general to study unexplained aerial phenomena. Podesta and his group has asked the Pentagon to declassify its UFO records and therefore provide scientists (6) ____ data that will help in the study of UFOs. CFI has requested the release of information on several UFO cases, starting with the Kecksburg, Pennsylvania, incident. This incident took (7) ____ in 1965 when a large acorn-shaped object, the size of a small car, crashed in Pennsylvania. Some analysts say it could have been the spacecraft Kosmos 96 that had been launched towards Venus by the Soviet Union, but failed to escape Earth’s (8) ____. Others say the object did not look anything like spacecraft built on Earth in 1965. (9)___, the people of Kecksburg want to know what happened. On that (10) ____, hundreds of eyewitnesses watched a fiery streak of light descend from the sky towards Earth. Officials explained that nothing was found or recovered and that maybe the fireball in the sky was a meteor. But many witnesses say they saw a number of military personnel from the Army and the Air Force search the woods, and later that evening, saw a large military tractor-trailer coming from the area carrying a large object under a tarp.

Why Should We Worry About What We Shouldn't?

It would be a lot easier to enjoy your life if there weren't so many things trying to kill you every day. The problems start even before you're fully awake. There's the fall out of bed that kills 600 Americans each year. There's the early-morning heart attack, which is 40% more common than those that strike later in the day. There's the fatal plunge down the stairs, the bite of sausage that gets lodged in your throat, the tumble on the slippery sidewalk as you leave the house, the high-speed automotive pinball game that is your daily commute.

Other dangers stalk you all day long. Will a cabbie's brakes fail when you're in the crosswalk? Will you have a violent reaction to bad food? And what about the risks you carry with you all your life? The father and grandfather who died of coronaries in their 50s probably passed the same cardiac weakness on to you. The tendency to take chances on the highway that has twice landed you in traffic court could just as easily land you in the morgue.

Shadowed by peril as we are, you would think we'd get pretty good at distinguishing the risks likeliest to do us in from the ones that are statistical long shots. But you would be wrong. We agonize over avian flu, which to date has killed precisely no one in the U.S., but have to be cajoled into getting vaccinated for the common flu, which contributes to the deaths of 36,000 Americans each year. We wring our hands over the mad cow pathogen that might be (but almost certainly isn't) in our hamburger and worry far less about the cholesterol that contributes to the heart disease that kills 700,000 of us annually.

We pride ourselves on being the only species that understands the concept of risk, yet we have a confounding habit of worrying about mere possibilities while ignoring probabilities, building barricades against perceived dangers while leaving ourselves exposed to real ones. Six Muslims traveling from a religious conference were thrown off a plane last week in Minneapolis, Minn., even as unscreened cargo continues to stream into ports on both coasts. Shoppers still look askance at a bag of spinach for fear of E. coli bacteria while filling their carts with fat-sodden French fries and salt-crusted nachos. We put filters on faucets, install air ionizers in our homes and lather ourselves with antibacterial soap. "We used to measure contaminants down to the parts per million," says Dan McGinn, a former Capitol Hill staff member and now a private risk consultant. "Now it's parts per billion."

At the same time, 20% of all adults still smoke; nearly 20% of drivers and more than 30% of backseat passengers don't use seat belts; two-thirds of us are overweight or obese. We dash across the street against the light and build our homes in hurricane-prone areas and when they're demolished by a storm, we rebuild in the same spot. Sensible calculation of real-world risks is a multidimensional math problem that sometimes seems entirely beyond us. And while it may be tree that it's something we'll never do exceptionally well, it's almost certainly something we can learn to do better.

Part of the problem we have with evaluating risk, scientists say, is that we're moving through the modem world with what is, in many respects, a prehistoric brain. We may think we've grown accustomed to living in a predator-free environment in which most of the dangers of the wild have been driven away or fenced off, but our central nervous system--evolving at a glacial pace--hasn't got the message.

To probe the risk-assessment mechanisms of the human mind, Joseph LeDoux, a professor of neuroscience at New York University and the author of The Emotional Brain, studies fear pathways in laboratory animals. He explains that the jumpiest part of the brain--of mouse and man--is the amygdala, a primitive, almond-shaped clump of tissue that s

Jim was born after his elder brother and sister. He could learn many things from them. Soon, he developed his own way of doing things by developing his mind through his interest in creating stories. He read more than most children and he gathered his inspiration from history books. In school, his athletic interests were basketball and bike, especially high jump. When he found he could jump a little higher than most students, he decided that jumping over a high bar would be his specialty.

Jim continued his learning interest in history which included serious college study, and a Master's degree. He is now a university professor at a small university. In the United States there are many schools that have history departments. There are large universities with as many as 60 thousand students and small universities with as few as 2 000 students. His degree from a large university with a strong history department has helped him get a good job.

听力原文：W: I'll go over to the recycling center this after noon. Would you like me to take your old newspaper and paper bags along?

M: I do have a lot of papers and magazines down in the basement. Volunteers used to come by these apartments regularly to collect waste paper. I still save it. But people seldom ask for nowadays and I've never gone over to the recycling center myself.

W: That's typical. A few years ago, people were really enthusiastic about reusing waste paper. Unfortunately, interests have been decreasing lately. Manufacturers now usc wastepaper for things like they need to find new commercial uses for recycled paper.

M: I suppose things like reading cards, calendars and writing paper could be made from it too. But recycled paper usually has a dingy color, doesn't it?

W: Well, it wouldn't be suitable for art books or high-quality magazine paper. But who cares about the drab color if the waste paper can take the place of the virgin woods, pulp and so help to preserve forests.

M: You are right. I'll bring my waste paper over to your apartment a little while. Thanks for offering to take it.

听力原文：M: Are you looking forward to your trip to Canada, Julie?

W: I can't wait to see Canada, but I'm scared of the journey. My husband insists on flying, but I want to sail. Planes make me nervous.

M: There's nothing to be frightened of. How many planes fly across the Atlantic every day?

W: I've no idea. Hundreds, I suppose.

M: And how often do you hear of a crash? ... Once or twice a year?

W: Yes, but sere planes fly so high and fast flint once is enough.

M: Look, there are more mad casualties per day than air deaths per year. Air transport is really safe compared with road transport.

W: I'd still prefer to go by sea. Ships may not travel fast, but at least you can relax, I'd love a trip on a luxury liner like the Queen Elizabeth Ⅱ.

M: It's fine ff you're a good sailor, but have you ever traveled far in a rough sea?

W: No. I've only been in a boat once. I sailed down the River Thames on a sightseeing tour... But in any case, I'd rather be seasick than dead.

A．The transportation of the trip.

B．The air-sick.

C．The sea-sick.

W: That’s typical. A few years ago people were really enthusiastic about musing waste paper. Unfortunately, interest has been decreasing lately. Manufacturers now use waste paper for things, like paper bags, towels, napkins and boxes. But the demand is down. I think they need to find new commercial uses for recycled paper.
