UNIT 2 Section One Tactics for listening Part 1 Sport Dictation My Mother

My mother was an efficient (1) taskmaster who cooked, cleaned and shopped for nine people (2) on a daily basis. She was a disciplinarian* who would (3) make us seven kids walk up and down the stairs a hundred times if we clumped like (4)field hands to-dinner. She also enlisted us to help her in the day's (5) chores.

My mother believed that each of her children had a special (6) knack that made him or her invaluable on certain (7) missions. My brother Mike, for example, was believed to have especially (8) keen eyesight. He was hoisted up as a human (9) telescope whenever she needed to see something (10) far away. John was the climber when a kite (11) got caught. My own job was navigator for our (12) gigantic old Chrysler.

But my mother's (13) ability to get work done well was only (14) one side. She also had an (15) imagination that carried her in different directions. That (16) allowed her to transcend her everyday life. She did not (17) believe in magic as portrayed on a stage, but (18) valued instead the sound of a metal bucket being (19) filled by a hose, or the persistence of a dandelion at the (20) edge of a woodpile.

Part 2 Listening for Gist

For hundreds of years man has been fascinated by the idea of flying. One of the first men to produce designs for aircraft was Leonardo da Vinci, an Italian artist who lived in the fifteenth century. However, it was not until the eighteenth century that people began to fly, or perhaps it would be better to say float, across the countryside in balloons. The first hot-air balloon was made in April 1783 by the Montgolfier brothers in France.

In the following years many flights were made by balloon. Some of the flights were for pleasure and others were for delivering mail and for military purposes, such as observation and even bombing. However, in the late nineteenth century, airships superseded balloons as a form of

transport.

Airships came after balloons. The first powered and manned flight was made by a Frenchman, Giffard, in September 1852. His airship, powered by steam, traveled twenty-seven kilometers from Paris to Trappes at a speed of eight kilometers per hour. However the days of the airship were numbered as the aero- plane became increasingly safe and popular. Exercise Directions: Listen to the passage and write down the gist and the key words that help you decide.

1. This passage is about the early history of flying.

2. The key words are designs, an Italian artist, fifteenth century, eighteenth century, fly, float, balloons, hot-air balloon, April 1783, airships, September 1852, aeroplane.

Section Two Listening Comprehension

Part 1 Dialogue

Buying a Car

A: Good morning, can I help you? B: Yes, I'm interested in buying a car. A: Have you anything in mind? B: Not really.

A: What price are you thinking of? B: Not more than ￡13,500.

A: Let's see now ... Over there between the Lancia and the Volvo is a Mini. It costs ￡12,830 and is cheap to run: It does 38 miles per gallon. Or there's the Citroen, behind the Mini. It costs ￡12,070 and is even cheaper to run than the Mini: It does 45 miles per gallon. It's not very fast though. It only does 69 miles per hour.

B: No, I think the Mini and the Citroen are too small. I've got three

A: Well, there's the Toyota over there, to the left of the Peugeot. It's very comfortable and costs ￡13,040. It's cheap to run too, and it also has a built-in radio. Or there's the Renault at the back of the showroom, behind the Peugeot. It costs a little more, ￡13,240, but it is cheaper to run. It does 40 miles per gallon and the Toyota only does 36 miles per gallon.

B: What about that Volkswagen over there, in front of the Toyota? A: That costs a little more than ￡13,500 but it's a very reliable car. It's more expensive to run than the others: It does 34 miles per gallon, but it's faster. Its top speed is 90 miles per hour. The Toyota's is 80 miles per hour and the Renault's is 82 miles per hour. B: How much does it cost?

A: ￡13,630 and that includes a 5-year guarantee. B: And the Fiat next to the Volkswagen?

A: Again that's more than ￡13,500, but it's cheaper than the Volkswagen. It costs ￡13,550.

B: Hmm well, I'll have to think about it and study these pamphlets. How much is that Peugeot incidentally, behind the Lancia? A: Oh, that's expensive. It costs ￡15,190.

B: Yes, that is a bit too much. Thank you very much for your help. Goodbye.

Part 2 Passage The Wrights’ Story

On the morning of December 17, 1903, between 10:30 a.m. and noon, four flights were made, two by Orville Wright and two by Wilbur Wright. The starts were all made from a point on the level sand about 200 feet west of our camp, which is located a quarter of a mile north of the Kill Devil sand hill, in Dare County, North Carolina.

The wind at the time of the flights had a velocity* of 27 miles an hour at 10 a.m., and 24 miles an hour at noon, as recorded by the anemometer* at the Kitty Hawk Weather Bureau Station.

The flights were directly against the wind. Each time the machine started from the level ground by its own power alone with no assistance from gravity or any other source whatever.

After a run of about 40 feet along a monorail* track, which held the machine 8 inches (20 centimeters) from the ground, it rose from the track and under the direction of the operator climbed upward on an inclined course till a height of 8 or 10 feet from the ground was reached, after which the course was kept as near horizontal as the wind gusts and the

limited skill of the operator would permit.

Into the teeth of a December gale （逆风） the \made its way forward with a speed of 10 miles an hour over the ground and 30 to 35 miles an hour through the air.

It had previously been decided that for reasons of personal safety these first trials should be made as close to the ground as possible. The height chosen was sufficient for maneuvering* in so gusty a wind and with no previous acquaintance with the conduct of the machine and its controlling mechanisms. Consequently the first flight was short.

The succeeding flights rapidly increased in length，and at the fourth trial a flight of 59 seconds was made, in which time the machine flew a little more than half a mile through the air and a distance of 852 feet over the ground.

The landing was due to a slight error of judgment on the part of the aviator. After passing over a little hummock* of sand, in attempting to bring the machine down to the desired height, the operator turned the rudder* too far, and the machine turned downward more quickly than had been expected. The reverse movement of the rudder was a fraction of a second(转瞬间，顷刻) too late to prevent the machine from touching the ground and thus ending the flight.

As winter was already well set in, we should have postponed the trials to a more favorable season, but we were determined to know whether the machine possessed sufficient power to fly, sufficient strength to withstand the shocks of landings and sufficient capacity of control to make flight safe in boisterous* winds, as well as in calm air.

Exercise A Pre-listening Question Orville Wright (1871-1948), American aeronautical engineer, famous for his role in the first controlled, powered flight in a heavier-than-air machine and for his participation in the design of the aircraft's control system. Wright worked closely with his brother, Wilbur Wright (1867-1912), American aeronautical engineer, in designing and flying the Wright airplane.
