les 1, 2 and 3 before

Quicklink Ltd operates in the distribution and haulage industry and has achieved significant growth since its formation

in 1997. Its main activities comprise the door-to-door delivery of mail, parcels and industrial machinery.

Parcel 20%

Machinery 50%

(iii) On 1 June 2003, Quicklink Ltd entered into a fixed price contract for the provision of fuel for its delivery vehicles

for the three-year period ending 31 May 2006. For the year ending 31 May 2006 fuel costs will be as follows:

(a) £0·10 per kilometre in respect of the delivery of mail and parcels

(b) £0·50 per kilometre in respect of the delivery of industrial machinery.

Each vehicle owned by Quicklink Ltd is in use for 340 days per annum.

annum.

(v) Sundry operating costs (excluding fuel and salaries) of Quicklink Ltd amounted to £3,000,000 during the year

ended 31 May 2005.

(a) contract rates of Quicklink Ltd business will increase by 5%

(b) sales volumes are expected to remain at the same level as in the year ended 31 May 2005

(c) salaries and other operating expenses will increase by 4%.

December 2001. The purchase took effect on 1 June 2005. Celer Transport has main activities comprising the

delivery of mail, parcels and processed food. The managing director of Quicklink Ltd has expressed his view that

‘the acquisition of the Celer Transport business would constitute a good strategic move even though it is expected

to make a loss of £50,000 during the year ending 31 May 2006’.

The information contained in notes (viii–xii) below relates to the business of Celer Transport in respect of the year

ending 31 May 2006:

in application during the year ended 31 May 2005 as the basis of charging for mail and parcel deliveries to

Celer Transport clients during the year ending 31 May 2006. This is due to the fact that Quicklink Ltd had

higher client billing rates than Celer Transport and the board of directors recognised that it would have been

difficult to adopt company-wide billing rates with effect from 1 June 2005.

根据以下内容回答下列各题, One of the greatest problems for those settlers in Nebraska in t
he last quarter of the previous century was fuel. Little of the state was forested when the first settlers arrived and it is probable that by 1880, only about one-third of the originally forested area remained, down to a mere 1 percent of the states 77,000 square miles. With wood and coal out of the question, and with fuel needed year-round for cooking, and during the harsh winter months for heating, some solution had to be foun d. Somewhat improbably, the buffalo provided the answer. Buffalo chips (干粪块) were found to burn evenly, hotly, and cleanly, with little smoke and interestingly, no odor, Soon, collecting them became a way of life for the settlers children who would pick them up on their way to and from school, or take part in competitions designed to counteract their natural reluctance. Even a young man, seeking to impress the girl he wanted to marry, would arrive with a large bag of chips rather than with a box of candy or a bunch of flowers. What is the main topic of this passage?

A.The solution to the Nebraska settlers fuel problem.

B.Life in Nebraska in the late ninteenth century.

C.The imporance of the American buffalo.

D.Deforestation in Nebraska in the late nineteenth century.

As if you needed another reason to hate the gym, it now turns out that exercise can exhaust not only your muscles, but also your eyes. Fear not, however, for coffee can perk them right up again

. During vigorous exercise, our muscles tire as they run out of fuel and build up waste products. Muscle performance can also be affected by a phenomenon called "central fatigue," in which an imbalance in the body's chemical messengers prevents the central nervous system from directing muscle movements effectively. It was not known, however, whether central fatigue might also affect motor systems not directly involved in the exercise itself—such as those that move the eyes. To find out, researchers gave 11 volunteers a carbohydrate solution either with a moderate dose of caffeine—which is known to stimulate the central nervous system—or as a placebo without, during 3 hours of cycling. After exercising, the scientists tested the cyclists with eye-tracking cameras to see how well their brains could still control their visual system. The team found that exercise reduced the speed of rapid eye movements by about 8%, preventing their ability to capture new visual information. The caffeine—the equivalent of two strong cups of coffee—was sufficient to counteract this effect, with some cyclists even displaying increased eye movement speeds, the team reports today in Scientific Reports. So it might be a good idea to get someone else to drive you home after that marathon.

The U.S. birthrate began to decline in the middle 1950's, resulting in a smaller College a
ge population starting in the middle 1970's. Something else happened in the 1970's: the price of oil increased tremendously, driving up the price of almost everything and making Americans aware that their large automobiles used a lot of gasoline. At the same time, foreign car manufacturers had begun to produce small fuel efficient cars in large quantities for the export market. Suddenly, the large, gas guzzling American cars were no longer attractive to American buyers, who began buying foreign cars by the thousands. The American automobile industry went into a recession. Thousands of automotive workers were laid off, as were thousands of people in industries indirectly connected with the auto industry. People who are laid off tend to keep what money they have for necessities, like food and housing. They do not have the extra money needed to send their children to college. Their children cannot pay their own college costs, because during a recession they cannot find jobs. High unemployment means that more state funds must be used for social service—unemployment benefits and to aid dependent children, for example—than during more prosperous times. It also means that the states have fewer funds than usual, because people are paying fewer taxes. Institutions of higher education depend on two major sources of income to keep them functioning: tuition from students and funds from the states. At the present time, there are fewer students than in the past and fewer state funds available for higher education. The colleges and universities are in trouble.

What is the main idea of this passage?

A.The rising of oil price drove up the price of everything.

B.There were many reasons why higher education was in trouble in the 1970's.

C.Birthrate began to decline in the U.S.A. in 1950's.

D.High unemployment caused a lot of social problems.
