听力原文:Brighton is a popular seaside town on the south coast of England. Not long ago so

听力原文: Brighton is a popular seaside town on the south coast of England. Not long ago some policemen at Brighton were very puzzled. There had been several serious accidents caused by motorists driving too fast. The police started to set up a speed trap. They measured a distance of 88 yards on a straight road and watched to see how long it took a car to travel that far. They knew that if a car took less than six seconds, it was traveling faster than the speed limit of 30 miles an hour.

When the policemen were ready, they hid behind a hedge and started to time passing vehicles. During their first half an hour, they caught five drivers. The policemen wrote down the number of each car and the name and address of the driver. But for the next half an hour the policemen did not see anybody driving too fast. They thought that this was very strange. One of them drove a quarter of a mile along the road and saw two students sitting on the grass. They were homing up a sheet of cardboard so that motorists could see it. On the notice one of the students had written: "Danger. Speed Trap."

The policemen took the notice away and wrote down the names of the students. Later on they were each fined £5 for trying to stop the policemen from catching motorists who were breaking the law.

(33)

A.It would be normal if the car took just four seconds.

B.It would be normal if the car took six seconds.

C.It would be normal if the car took less than three seconds.

D.It would be normal if the car took less than six minutes.

Chair Co has developed a new type of luxury car seat. The estimated labour time for the fi
rst unit is 12 hours but a learning curve of 75% is expected to apply for the first eight units produced. The cost of labour is $15 per hour. The cost of materials and other variable overheads is expected to total $230 per unit.

Chair Co plans on pricing the seat by adding a 50% mark-up to the total variable cost per seat, with the labour cost being based on the incremental time taken to produce the 8th unit.

Required:

(a) Calculate the price which Chair Co expects to charge for the new seat. Note: The learning index for a 75% learning curve is –0·415. (5 marks)

(b) The first phase of production has now been completed for the new car seat. The first unit actually took 12·5 hours to make and the total time for the first eight units was 34·3 hours, at which point the learning effect came to an end. Chair Co are planning on adjusting the price to reflect the actual time it took to complete the 8th unit.

Required:

(i) Calculate the actual rate of learning and state whether this means that the labour force actually learnt more quickly or less quickly than expected. (3 marks)

(ii) Briefly explain whether the adjusted price charged by Chair Co will be higher or lower than the price you calculated in part (a) above. You are NOT required to calculate the adjusted price. (2 marks)

Passage Three People enjoy talking about "firsts." They like to remember their first love

Passage Three

People enjoy talking about "firsts." They like to remember their first love or their first car. But not all firsts

are happy ones. Few people enjoy recalling the firsts that are bad.

One of history's bad but important firsts was the first car accident. Autos were still young when it happened. The crash took place in New York City. The year was 1896. The month was May. A man from Massachusetts was visiting the city in his new car. At the time, bicycle riders were still trying to get used to the new set of wheels on the road. No one is sure who was at fault. In any case, the bike and the car collided. The man on the bike was injured. The driver of the car had to stay in jail and wait for the hospital report on the bicycle rider. Luckily, the rider was not killed.

Three years later, another automobile first took place. The scene was again New York City, a real estate broker named Henry Bliss stepped off a streetcar. He was hit by a passing car. Once again, no one is sure just how it happened or whose fault it was. The driver of the car was put in jail. Poor Mr. Bliss became the first person to die in a car accident.

44. In each accident the driver was ______.

A. found guilty

B. set free

C. laughed at

D. put in jail for a while

As prices and building costs keep rising, the "do—it—yourself" (DIY) trend (趋势) in the U

As prices and building costs keep rising, the "do—it—yourself" (DIY) trend (趋势) in the U.S. continues to grow.

"We needed furniture(家具) for our living room," says John Ross, "and we just didn't have enough money to buy it. So we decided to try making a few tables and chairs. "(76) John got married six months ago, and like many young people these days, they are struggling to make a home at a time when the cost of living is very high. The Rosses took a two-week course for $ 280 at a night school. Now they build all their furniture and make repairs around the house.

Jim Hatfield has three boys and iris wife died. He has a full—time job at home as well as in a shoe making factory. Last month, he received a car repair bill for $ 420. "I was deeply upset about it. Now I've finished a car repair course, I should be able to fix the car by myself."

John and Jim are not unusual people. In order to save money, most families in the country are doing everything they can so that they can fight the high cost of living. If you want to become a "do—it yourselfer", you can go to DIY classes. And for those who don't have time to take a course, there are books that tell you how you can do things yourself.

We can learn from the text that many newly married people ______.

A.find it hard to pay for what they need

B.have to learn to make their own furniture

C.take DIY course run by the government

D.seldom go to a department store to buy things
