76. __________
While everybody enjoys fresh cut flowers around his house, few people know how to keep them for as long as possible. This may be done by keeping in mind a few simple facts. The key to keeping fresh cut flowers for a week or more without floral preservatives(which contain biocides that kill bacteria and fungus) is to keep the water fresh and the stems free of air pockets so they can continue to draw up water.
77. __________
An important thing to remember about cut flowers is that they are sensitive to temperature. For example, studies have shown that cut carnations(康乃馨) retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowers at the right temperatures is probably the most important aspect of flower care.
78. __________
Flowers are not intended by nature to live very long. Their biological purpose is simply to attract birds or insects, such as bees, for pollination (授粉). After that, they quickly dry up and die. The process by which flowers consume oxygen and produce carbon dioxide, called respiration (呼吸), generates the energy the flower needs to give the flower its shape and colour. The making of seeds also depends on this energy. While all living things respire, flowers have a high level of respiration. A result of all this respiration is heat, and for flowers the level of heat relative to the mass of the flower is very high. Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration, the sooner the flower dies.
79. __________
How, then, to control the rate at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature. We know that respiration produces heat, but the reverse is also true. Thus by maintaining low temperatures, respiration is reduced and the cut flower will age more slowly.
80. __________
Another vital factor in keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to “drink” water that is dirty or otherwise polluted. Even when water looks and smells clean, it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, household chlorine bleach (含氯漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach(at 4% solution) be added to each litre of water. The water and solution should also be replaced each day.

Directions: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that fits the context.
The central problem of economics is to satisfy the people's and nation's wants.
The problem we faced with is that our resources, here identified as money are __50__. The only way we can solve the problem is to make choices. After looking at our resources, we must examine our list of __51__ and identify the things we need immediately, those we can postpone, and __52__ we cannot afford. As individuals, we face the central problem involved in economics---deciding how to allocate(分配) our limited resources to provide __53__ with greatest satisfaction of our wants. Nations face the same problem. As a country's population __54__, the need for more goods and services grows correspondingly. Resources necessary to production may increase, but there are __55__ enough resources to satisfy the total desires of a nation. Whether the budget meeting is taking place in the family living room, in the conference room of the corporation __56__ of directors, or in the chamber of the House of Representatives in Washington, the basic problem still exists. We need to find __57__ of allocating limited resources in order to satisfy unlimited wants. A short time ago, economists divided goods into two categories, free and economic. The former, like air and water, were in __58__ abundance(丰富) that economists had no concern for them. After all, economics is the __59__ of scarcity and what to do about it. Today many of these "free goods" are __60__ very expensive to use. Population has made clean air and water expensive for producers extra cost, and __61__ taxpayers who pay for the government's involvement in cleaning the environment. In the 1990s, almost all goods are __62__. Only by effort and money __63__ obtained in the from people wish.
Meeting needs of people and the demands from resource available __64__ the basic activity of production. In trying to meet unlimited wants from limited economic goods, production leads to new problems in economics.

Section B
Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.
(A)
Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict,” jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled.” Today David wears casual clothes---khaki pants and sports shirt---to the office. He hardly ever wears necktie. “I’m working harder than ever,” David says, “and I need to feel comfortable.”
More and more companies are allowing their office workers to wear casual clothes to work in the United States. The change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday (but only on Friday). This became known as “dress-down Friday” or “casual Friday.” “What started out as an extra one-day-a-week benefit for employees has really become an everyday thing,” said business consultant Maisly Jones.
Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code. “A lot of young people don’t want to dress up for work,” says the owner of a software company, “so it’s hard to hire people if you have a conservative dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Strauss and Company, 85 percent of employers said that they believe that casual dress improves employee morale. Only 4 percent of employers said that casual dress has a negative impact on productive. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.”

66. David Smith wears casual clothes now, because________
A. they make him feel at ease when working
B. he cannot afford to buy expensive clothes
C. he looks handsome in casual clothes
D. he no longer works for any company

B. Comfortable clothes make employees more productive
C. A casual clothes code is welcomed by young employees
D. All the employers in the U.S are for casual office wear.

Two-thirds of U.S. consumers have yet to finish their holiday shopping, and 41 percent expect to finish at least a week prior to Christmas, according to a new survey.
One-fourth of __41__ will be shopping the week leading into Christmas, __42__ Christmas Eve, according to the first annual American Express Spending and Saving Tracker research report.
"Actually, we found in this holiday season there is this game of watching and waiting ... that deals will get sweeter as the clock winds down," said Mona Hamouly, a spokeswoman for the report.
Some 62 percent of consumers are waiting until the last minute to shop for the holiday. Thirty-one percent are waiting for the best deals before finishing their shopping, while about 20 percent plan to do so at the last minute because they are still saving or are busy, and one in 10 say they are waiting for that last pay __43__ before the holidays.
Hamouly said consumers seem to be "managing their cash flow and seeking out those great deals" this year.
Over the next 30 days, 65 percent of people expect to spend the same or more than they spent in the past 30 days and one-third __44__ to spend less, according to the survey prepared for American Express.
Hamouly said the weak economy was a large factor in consumers' __45__ toward shopping, with many feeling cash-strapped.
In addition to a __46__ sample of consumers, the survey targeted two sub-groups -- those designated as "affluents" and "young professionals."
Affluents were __47__ as having a minimum __48__ household income of $100,000, while young professionals were those who were less than 30 years old, had a college degree and a minimum annual household income of $50,000.
During the next 30 days, among consumers who expect to spend more, 56 percent say they will be spending the most on holiday gifts.
More than 40 percent expect to spend less in the next month because they are trying to save money, the prices of goods have increased, or they want to maintain a __49__. One-third cite the need to reduce their debt.
"Even for the affluent population, they want to get the best deals too," Hamouly said.
The two top items consumers will be buying over the next 30 days are groceries and holiday gifts.
