Basic tips for preserving cut flowers C. Role of Respiration D. Most Important Aspect of Flower Care E. Need for Clean Water F. Ways of Stopping Respiration 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 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 . After that, they quickly dry up and die. The process by which flowers consume oxygen and produce carbon dioxide, called respiration , 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 can be used in small quantities. It is recommended that 15 drops of chlorine bleach be added to each litre of water. The water and solution should also be replaced each day. 查看更多

Section C

Directions: Read the following text and choose the most suitable heading from the list A-F for each paragraph.  There is one extra heading which you do not need.(本题请涂在答题卡上)

(E)

A.The disadvantage(s) of credit cards.

B.Clever choice of credit cards.

C.The benefits credits cards bring.

D.Avoidance of economic trouble by using credit cards wrongly.

E. People’s misunderstanding about credit cards.

F. Ways to save on the interest.

 

80.______ Although credit cards are already a more acceptable part of the financial dealings, they are still regarded, especially in the time of a serious economic crisis, by many as being a major part of the “live now pay later” system.  Along with hire-purchase regulations, credit cards, according to some, provide encouragement to spend more money.  However, it’s only the fool who is dominated by the temptation to live, temporarily at least, beyond their means, and such people would no doubt manage to do so even without credit cards.

81.______ Advertising campaigns have already promoted a growing realization of the advantages of these small pieces of plastic.  They avoid the need to carry large amounts of cash and are always useful in emergencies.  And the monthly credit card bill is a loyal booker keeping your monthly purchase record and indicating your buying habits.

82.______ All the credit card organizations charge interest on a monthly basis which may work out as high as two percent a year.  But sensible purchase using a card can mean that you obtain up to seven weeks interest-free credit.  Using the card abroad, where items frequently take a long time to be included on your account, can extend this period even further.

83.______ It is worthwhile consulting more credit card companies before deciding on a particular credit card.  It is necessary to consider the amount of credit granted, interest rates, which may vary slightly; the number and range of outlets, though most cards cover major stores.

84.______ Undoubtedly, if used wisely, a credit card can cost nothing, or at lease help to tide you over a period of financial difficulty.  However, we should also remember that the wrong use of the little plastic may drag us deep into financial troubles.  More than half of the American personal bankruptcy(破产) and credit failure cases are connected with the wrong use of the credit card.  Therefore, every time you open your wallet and reach for a credit card, remember to ask yourself:” Is the item necessary to me?” and “Do I really need so many credit cards?”

Section C

Directions: Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.

A  Preparation for taking a citizenship test

B  Citizenship tests in European countries

C  Cultural differences and conflicts

D  New US Citizenship Test

E  Different views on the new citizenship test

F  Goal of the new citizenship test

 

80.

 

Last week, a sample of the new US citizenship exam was released by the US Citizenship and Immigration Services(US-CIS). It will be tried out in 10 cities early next year to replace the current test in 2008. Instead of asking how many stripes the US flag has, as the current test does, the new one asks why there are l3 stripes. Instead of having to name the branches of government, an applicant is asked to explain why there are three.

81.

 

The newly released US citizenship exam has included more information and knowledge. People who take it need to know more about the adopted country and have a deeper insight into its culture and values. “The goal is to make it more meaningful.” explains Emilio Gonzalez, director of the US—CIS. Immigrants who pass it are expected to have a better “understanding and respect” for US civic values, Gonzalez says.  

82.

 

The US isn't the only country dealing with citizenship tests that aim to get a “shared commitment” from immigrants for their adopted country's “values”. In recent years, in addition to the usual requirement of language/work skills and economic status, several European countries have adopted citizenship tests. Britain introduced a new citizenship test last November. In March, a new Dutch law took effect requiring all would-be immigrants to take a citizenship test. It involved watching a video showing nude(裸体的)women bathing at beaches and gay(同性恋的)men kissing in public. The aim was to ensure that “newcomers will be comfortable with the country's liberal social mores(风俗)”.

83.

 

Europe has been known for welcoming immigrants for decades. But, today, the fact is that some immigrants are kept apart from local citizens by culture and they become hostile (敌对的) to each other. Promoting unity has become a major concern for European countries, after the rioting in Muslim ghettoes(少数民族聚居区)in France and the killing of Dutch public figures by religious extremists.

84.

 

Officials believe that a person's attachment to a country can be tested by his or her knowledge of the country. However, some critics say that the changes can do little to help people assimilate(同化)themselves. “Immigration is a culture war today. Is giving a new test the right way to lessen the accusations in that fight?” says Ali Noorani, of the Massachusetts Immigrant and Refugee Advocacy Coalition(难民辩护联盟).

Section C

Directions: Read the following text and choose the most suitable heading from the list A-F for each paragraph. There is one extra heading which you do not need.

(D)

A. the future of computer-human relationship

B. the programming system of the computer

C. the reason of the complexity of the human brain

D. the possibility of a real supercomputer

E. the way for computers to kill humans

F. the shortages of the computer compared with a human brain

76. ____________________

The difference between a human brain and a computer is more complicated than we can imagine. The large mammalian brain is the most complicated thing, for its size. Though the human brain only weighs three pounds, in that three pounds are ten billion neurons and a hundred billion cells. The many billions of cells are interconnected in such a vastly complicated network that we can’t begin to explore as yet.

77. ____________________

Even the most complicated computer man has yet built can’t compare with the brain.  Computer switches and processes number in the millions rather than in the billions. What’s more, the computer switch is just an on-off device, whereas the brain cell is itself possessed of a complex structure.

78. ____________________

It’s frequently said that computers solve problems only because they are “programmed” to do so. They can only do what men have them do, in which way it is like the human brain. We can also do what we are “programmed” to do. Our genes “program” us the instant the zygote (授精卵) is formed, and our potentialities are limited by that “program.”

79. ____________________

Surely, though, if a computer can be made complex enough, it can be as creative as people.  If it could be made as complex as a human brain, it could be the replacement of a human brain and do whatever a human brain can do. Then the real supercomputer comes along.

80. ____________________

In other words, once we pass a certain critical point, the computers will gain a dominating position and present a complexity explosion. In a very short time thereafter, computers may exist not only taking after the human brain, but far passing it. When the time comes, we might as well step aside and hand over all our work to them and really have them serve us.
