1、現(xiàn)代大學(xué)英語(yǔ)聽(tīng)力2聽(tīng)力原文及題目答案Unit 2Unit 2Task 1【答案】1) b 2) a 3) d【原文】Texas was the biggest state before Alaska became the forty-ninth state in 1959. One good way to understand the size of Texas is to learn about its weather. Different parts of the state have very different kinds of weather.Laredo is one of the

2、 hottest cities in the United States in summer. The best time to visit Laredo is in winter, when it is pleasantly warm.Amarillo gets very cold in winter. Sometimes there is more snow in Amarillo than in New York, which is a northern city. Summers are better, but sometimes it gets quite hot. The best

3、 time to visit Amarillo is in the autumn when it is cool.If anyone asks you about the weather in Texas, ask him, “What part of Texas do you mean？”Task 2【答案】A.1) T 2) F 3) FB. 1) d 2) c 3) cC. climate, reputation, extraordinary, unreliable, dry, wet, clear, dull, hot, cold, bad, mild【原文】Our friend, N

4、ick, whose English gets better and better, declared solemnly the other day that he thought that the British climate was wonderful, but the British weather was terrible. He went on to explain by pointing out that the British climate was a temperate one. This meant, he said, "that you could alway

5、s be certain that the weather would never be extreme at any rate not for any length of time never very hot and never very cold." He quite rightly pointed out that the rainfall in Britain, according to the statistics, was not very heavy. "Why then," he asked, "has the British clim

6、ate such a bad reputation?" He answered by saying it was because of the extraordinary, unreliable weather. There was no part of the year at which you could be certain that the weather would be dry or wet, clear or dull, hot or cold. A bad day in July could be as cold as a mild day in January. I

7、ndeed you could feel cold at almost any time of the year. Nick blamed drafty British houses for this, but agreed you could also blame the small amount of sunshine and a great amount of dampness. He advised every student coming to Britain to bring an umbrella and to understand the meaning of that spl

9、rthB.1. Ice near the North and South poles to melt2. to be slowly flooded and people living in these cities to move to higher land【原文】Cities change the climate around you. In the country, there are trees, grass, lakes, and streams. In hot weather, the trees and grass cool the area around them. Lakes

10、 and rivers also cool the area around them. But cities are not cooled in these natural ways. Cities are built of asphalt, concrete, iron, andsteel. There are few trees and usually not much grass. Rain falls onto the streets and into the sewers. When the summer sun shines, streets and buildings take

11、in the heat; after the sun sets, the streets and buildings throw off heat into the street. Once the sun sets, the countryside cools off, but a city may stay hot all night. Cities are hotter than the countryside in winter, too. Standing near a car with its motor running, winter or summer, you will fe

12、el the heat thrown off by the engine. The heat comes from the gasoline burned by the engine. This heat warms the air and the ground around the car. Thousands of running cars are almost like thousands of small fires burning. Carefully put your hand near a light bulb or television set. As you can see,

13、 electricity creates a lot of heat. This heat from electricity warms the house and the outside air. The heat given off by cities can affect the climate. Some experts even believe that cities can change the climate of the whole world. They think that air pollution may stop sunlight from reaching the

14、earth. If less sunshine reaches the earth, the earth may become cooler.Still other experts think the world will get warmer. If the world did get warmer, great changes would occur. Ice near the North and South poles would melt. This would make the oceans rise. Cities near oceans like Los Angeles, Bos

15、ton, and Miami would slowly be flooded. People living in these cities would have to move to higher land.Task 4【答案】A.1) b 2) cB. night, delight; morning, warning; gray, way, red, headC. 1) F 2) T 3) F【原文】A red sky at either dusk or dawn is one of the spectacular and beautiful weather predictors we ha

16、ve in nature. By closely observing this phenomenon, you can achieve short-range accuracy of the weather as good as, or better than your local weatherman. In the Bible, Jesus in Matthew 16, 2-3 is quoted as saying, “When it is evening, it will be fair weather: for the sky is red. And in the morning i

17、t will be foul weather today: for the sky is red” when speaking to the Pharisees. An old English weather proverb based on this passage is:Red sky at night, sailors delight.Red sky at morning, sailors take warning.OrEvening red and morning gray, Sends the traveler on his way.Evening gray, morning red

18、, Brings the rain down on his head.At dusk, a red sky indicates that dry weather is on the way. This is due to the sun shining through dust particles being pushed ahead of a high pressure system bringing in dry air. A red sky in the morning is due to the sun again shining through dust. In this case

19、however, the dust is being pushed on by an approaching low reassure system bringing in moisture. Don't confuse a red sky in the morning with a red sun in the morning. If the sun itself is red and the sky is a normal color, the day will be fair.Task 5【答案】1) c 2) b 3) d 4) c 5) c【原文】Mark: I am an

20、avid fly fisherman and frequently find myself on the river in a raft during lightning storms. We always have a debate at these times on where we are safest pulling into shore or staying on the water. Since I have heard one is safe in a car when lightning strikes I wonder if the raft floating on the

21、water is insulated, and therefore the safest place to be.Meteorologist A: We spoke with some scientists about your question, and they all agreed that under no circumstances should you remain on the water during a lightning storm. If your raft is made of rubber, you might feel that you're .well i

22、nsulated, but don't kid yourself. Typical lightning flashes travel 10 to 15 kilometers and can deliver as much as 100,000 amps of current. In comparison, a toaster uses about 10 amps of current. If lightning strikes the water near you, it will have no trouble traveling through a few extra centim

23、eters of rubber.Meteorologist B: So, if you're on the water and a thunderstorm approaches, get to the shore and seek shelter on land. Try a building or car. If neither is available, look for a cave, cliff, wall, or a group of trees. Never take shelter under an isolated tree-it's also a good

24、target for lightning.Task 6【答案】A.1) F 2) T 3) F 4) T 5) F 6) TB.Incredible, one minute, one kilometer, destroyed, lifted up, carried away, killed, injured【原文】Every spring and summer many inland areas are hit by tornados. A tornado is a kind of storm. It's a revolving, funnel-shaped column of air

25、 that moves through the sky at very high speeds. A tornado looks like a huge, black ice cream cone whirling through the sky. The speed of a tornado is very fast-it is believed to be between 200 and 700 kilometers per hour.Tornados form under very special weather conditions, and these special weather

26、 conditions occur most often in inland areas, such as the central United States. A tornado forms when a layer of warm, dry air is on top of a layer of cooler, moist air. This combination of dry, warm air above wet, cool air creates a condition that causes the lower layer of air to lift up. As the lo

27、wer air rises, both layers of air begin to rotate, to turn around and around. The air begins to rotate faster and faster because of centrifugal force. The tornado has a center called an “eye” and the air rotates quickly around this eye. As the air begins to rotate faster and faster, the tornado clou

28、d begins to grow downward; that is, it begins to form a funnel or cone, and this cone goes down toward the ground. The cone of air is dark because it develops from a dark rain cloud. As the cloud gets longer, as the cloud gets closer to the ground, it begins to pull up dirt from the ground. Then the

29、 funnel ofrotating air becomes very dark because of the dirt in it. As the tornado funnel gets longer, it begins to drag along the ground. When the tornado touches the ground, it does incredible damage. It usually touches the ground for only about one minute, and it usually travels along the ground

30、for only about one kilometer, but during that one minute, buildings are destroyed, trees are lifted up out of the ground, small objects are carried away, and sometimes people are injured or killed.Task 7【答案】A.1) b 2) a 3) bB.1) It has been nice weather during the day, but it is going to change at ni

33、stening to Radio Metro. Its two minutes to nine, and time for the latest weather for cast from Dan Francis at the London Weather Centre.Francis: Hello. It's been another warm and fine day for most of us. Temperatures in southeast England reached 26 degrees Celsius by mid-afternoon, and Brighton

34、had 15 hours of lovely sunshine. Further north it was a little cooler with maximum temperatures of around 21 degrees in southern Scotland, and in the far northwest of Scotland there were some light showers around midday. But the rest of the country, as I said, has been warm and dry with temperatures

35、 in the Midlands reaching 23 degrees Celsius by early afternoon though it was a little cooler along the west coast and in Northern Ireland. But already the weather is beginning to change, I'm afraid, and during the night showers will slowly move in from the Atlantic to reach south-west England a

36、nd the southern coast of Wales by early morning.The rest of the country will have a very mild, dry night with minimum temperatures no lower than 15 degrees in the south, a little cooler 11degrees or so in the north. Any remaining showers in northwest Scotland will pass quickly to leave a mild, dry n

37、ight there too. And now the outlook for Friday and the weekend. Well, southern Europe will, once again, get the best of the weekend weather, and if your holiday starts this weekend, then southern Spain is the place to go, with temperatures of 34 degrees along the Mediterranean coast. At the eastern

38、end of the Med, too, you can expect uninterrupted sunshine and temperatures of up to 32 degrees Celsius in Greece and southeast Italy, but further north the weather's not so settled. Much of France, Belgium and the Netherlands will be cloudy with occasional rain, and maximum temperatures will be

39、 around 22 degrees very disappointing for this time of the year. Scotland and Northern Ireland will have heavy rain for much of the weekend and temperatures will drop to a cool 17 degrees. Across most of England the weather will be cloudy but mainly dry with sunny periods. And when the sun does come

40、 out, temperatures could rise to a maximum of 23 degrees.Task 8【答案】Natural PhenomenaAir Pressure (Rise or Fall)CausesFaraway objects are focused.FallThe dust particles begin to settle to the ground in thinner air and the air clears.Birds calls become Sharper.FallInstead of traveling upward and outwa

42、ngsSmoke rise high in the airRiseSmoke rises with thicker air.Elderly peoples joints ache.FallThe gas in our bodies expands in lower air pressure.【原文】As the air pressure around you either rises or falls, many changes in nature occur. Most of these are very obvious changes while others are of a more

43、subtle nature. Mountains and other far away objects will appear to be much closer and more sharply focused as wet weather approaches and the air pressure drops. The dust particles in the air begin to settle to the ground and the air clears, allowing you to see more details of faraway objects. As a h

44、igh pressure front approaches and the air becomes “thicker,” more dust particles become suspended in air and things take on their normal somewhat hazy appearance.“Sharp horns on the moon threaten bad weather.” This and a bright, clear moon are good indicators that wet weather is on the way. As the a

45、ir clears of dust particles ahead of a low pressure system, the moon appears to come closer and be more sharply focused due to the lack of dust.Sound also becomes sharper and more focused prior to stormy weather. Instead of traveling upward and outward into the atmosphere sound waves are bent back t

46、o the earth and their range extended. Bird calls sound sharper, and, at my house, we can hear the blowing of the train horn as it rumbles through the valley below.If you find yourself out in a marsh or swamp and the air really seems to stink more than normal, expect rainy weather. This happens when

47、the pressure drops and the methane trapped on the bottom of the swamp is released in greater quantities. In reverse, as fair weather approaches and the pressure rises, things won't smell quite so strong.Birds and bats have a tendency to fly much lower to the ground right before a rain due to the

48、 “thinning” of the air. They prefer to fly where the air is the most dense and they can get greater lift with their wings. With high pressure and dry air, the atmosphere becomes denser and they can easily fly at higher altitudes.Smoke rising straight into the air means fair weather and smoke hanging

49、 low means rain is on the way. This is pretty much the same as with the birds and methane in the swamp. When high pressure approaches, smoke will rise whereas with low pressure it can't rise and tends to lay low.Remember a grandparent talking about how their corns, bunions, or joints ached right

50、 before a rain? Again, this is due to the decreasing atmospheric pressure allowing the gas in our bodies to expand.Task 9【答案】A. Statements 3, 6, 7 are true.B.fcadbe C. 1) F 2) T 3) F 4) FD.1) d 2) b【原文】It was 1974. Richard Nixon was still president. Kidnapped heiress Patty Hearst was still missing.

51、In Xenia, a pretty spot of 25,000 people amid fields of soybeans and corn, American Graffiti was held over at the Cinema. The Xenia Hotel offered a chicken and dumpling dinner for $2.25, but everyone flocked to the A&W drive-in for burgers and root beer floats. That's where five of the bodie

52、s were found after the storm.In all, 33 people died in Xenia's tornado, the deadliest of 148 storms that raged through 13 states during the infamous "Super Outbreak'' of tornadoes April 3 to 4, 1974. In 16 hours and 10 minutes, 330 people were killed and nearly 5,550 were injured fr

53、om Illinois to Georgia. Though the Xenia death toll has been matched by other killer storms, the degree of devastation makes the city's tornado among U.S. history's most destructive. The storm still is studied in colleges by aspiring meteorologists, a textbook case of a rare Category F-5, th

54、e most intense of tornadoes.On that fateful day, I was a young boy of 8 years old. We lived in the Arrowhead Subdivision. That afternoon I was around the corner playing with some neighbor kids. I thought I could hear my father calling me, so I ran back to the house. Thinking back now, there is no wa

55、y I would have been able to hear him. I was too far away for a voice to have traveled in the afternoon noise. Besides, Dad had a very bad case of tonsillitis that day. Like I was saying, I went back home and got through the door just in time to answer the ringing phone. On the other end of the phone

56、 was my Mother. Mom was working. She told me she heard a bad storm was on the way. She told me to make sure the garage door was shut and to stay inside. After I hung up the phone, I settled down to watch The Dennis Show. To this day I can vividly remember the electricity going out. I looked out the

57、large window in the living room and didn't have a clue as to what I was looking at.Dad was asleep on the couch, so I woke him up to look. Dad looked and said to get into the bathroom. We sat on the floor. Dad had his back to the door and his feet pushing against the wall opposite the door. I remember that as soon as we sat down, the windows broke. Glass blew under the door, and the sound was tremendous. I know it really didnt take too long for the tornado to go past, b
