Ever since news of widespread food recalls caused by a carcinogenic dye broke, there has been confusion（混淆） over possible links to the country of the same name, but Sudan officials say there is no connection whatever.
Sudan?1 is a red industrial dye that has been found in some chilli powder, but was banned in food products across the European Union (EU) in July 2003.
Since the ban was put in place, EU officials have been striving to remove some food products from the shelves. So far 580 products have been recalled.
Last week Sudan’s Embassy in the United Kingdom asked the Food Standards Agency (FSA) for clarification of the origin of the dye’s name.
Omaima Mahmoud Al Sharief, a press official at Sudan’s Embassy in China, explained the purpose of the inquiry was to clear up any misunderstanding over links between the country and the poisonous dye.
　　"We want to keep an eye on every detail and avoid any misunderstanding there," she said. "Our embassy to Britain asked them how the dye got that name and whether the dye had something to do with our country. But they told us there was no relationship."
The FSA, an independent food security watchdog in Britain, received a letter from the Sudanese embassy last week.
　"They asked us why the dye is named Sudan, however, we also do not know how it got the name," she said. "People found the dye in 1883 and gave it the name. Nobody knows the reason, and we cannot give any explanation before we find out."
Sudan dyes, which include Sudan?1 to 4, are red dyes（顏料） used for colouring solvents（溶劑）, oils, waxes, petrol, and shoe and floor polishes. They are classified as carcinogens by the International Agency for Research on Cancer.
小題1: What does the underlined word mean in paragraph one?
A．Causing cancer.B．Having side effect.C．Containing poison.D．Poisonous.
小題2:How did the Sudan?1 get its name?
A．The dye is often produced in Sudan.
B．The dye has something to do with the country named Sudan.
C．Nobody is sure of the origin of the name.
D．Many foods produced in Sudan contain the dye.
小題3:We can infer from the passage that.
A．the Sudan government is paying much attention to the food safety
B．Sudan?1 is often used to be added to the food
C．people didn’t realize the danger of Sudan?1 until 2003
D．many food shops will be closed down
小題4:Which of the following is the best title?
A．Keep away from Sudan?1
B．No Sudan?1 dye links to the country
C．How Sudan?1 dye got its name?
D．Pay attention to the food safety

小題1:A
小題2:C
小題3:B
小題4:B

小題1:詞義猜測題。根據(jù)They are classified as carcinogens by the International Agency for Research on Cancer. 可知這個詞與癌癥有關，故可推出carcinogenic意為"致癌的"。
小題2:細節(jié)題。根據(jù)People found the dye in 1883 and gave it the name. Nobody knows the reason, and we cannot give any explanation before we find out.可知還沒有人知道"蘇丹紅"名稱的由來。
小題3:推斷題。根據(jù)EU officials have been striving to remove some food products from the shelves. So far 580 products have been recalled.可知某些食品因含有"蘇丹紅"而被召回。故可推斷"蘇丹紅"經常用作食品添加劑。
小題4:主旨大意題。根據(jù)there has been confusion over possible links to the country of the same name, but Sudan officials say there is no connection whatever. 可知本文主要講"蘇丹紅"與蘇丹這個國家是否有聯(lián)系的問題，故B最佳。

Want to be a happy married couple? Consider having kids．
A new study found that having children boosts happiness．And the more, literally, the merrier．
But unmarried couples shouldn’t expect to find greater happiness through child-raising．The study, published in the Oct．14 online edition of the Journal of Happiness Studies, suggests that having children has little or no effect on boosting happiness among couples who aren’t hitched(和諧)．
The findings contradict previous research that suggested that having more offspring doesn't lead to greater happiness and might even make people less satisfied with their lives．One theory behind the conclusion is that parents don’t receive many rewards in return for the hard work of raising children．
The new study, however, notes that parents say children are one of the most important things in their lives, if not the most important．
The study found that life satisfaction for married people -- women especially -- goes up the more kids they have．Single, separated and co-habiting people, by contrast, report negative experiences．
“One is tempted to advance that children make people rich under the ‘right conditions’ -- a time in life when people feel that they are ready, or at least willing, to enter parenthood,” Dr．Luis Angeles, of the University of Glasgow in Scotland, said in a news release from the journal’s publisher．“This time can come at very different moments for different individuals, but a likely signal of its approach may well be the act of marriage．”
小題1:he underlined word “offspring” in the fourth paragraph can be replaced by _____．
A．generationB．childrenC．mothersD．marriage
小題2:The best title of this passage should be _______．
A．Children Are the Source of Happiness
B．Are You Happy Married Couple?
C．Married with Children Paves Way to Happiness
D．The Right Conditions of Having Children
小題3:Which of the following can be inferred from the passage?
A．The more children women have, the happier they are．
B．The more children the married women have, the more unsatisfied they become．
C．Raising kids can give any person happiness．
D．Without marriage, one woman had better not raise kids．
小題4:In the passage, the underlined part ‘right conditions’ refers to _______．
A．a time when the couple are ready and willing to become parents
B．the situation where the family is rich enough to raise a child
C．the situation where the couple are very happy
D．a time when the couple thinks raising children can boost happiness

Drinking wine in moderation improves the IQ and may boost mental agility in old people,according to Japanese researchers.
A study of the effects of alcohol on the middle aged and elderly found the average IQ of men who drink wine (whether made from grapes or rice) was 3.3 points higher than that of men who do not imbibe.
Similarly,the IQ of women drinkers showed an improvement of 2.5 points over their teetotal sisters.The findings are part of an ongoing study by Japan’s National Institute for Longevity into the links between human intelligence and what we eat and drink.
The tests measured general knowledge,powers of judgment and concentration in drinkers and non-drinkers over 40,all living in Aichi prefecture,central Japan,and sharing the same income level-roughly￡50 000 a year—and educational background.All were university graduates.
But while wine-drinkers appeared to be brighter,the same was not true of those who drank deer,shochu (a local gin) and whisky.
“The benefits of wine and sake (rice wine) in raising IQ could be due to substances they contain,such as polyphenol,which are believed to slow the ageing process,” Hiroshi Shimokata,head of epidemiology research,said.
It was premature to conclude,he added,that drinking wine or sake slowed the deterioration of brain functions in the elderly,or warded off senility.The research does,however,suggest that this is one way to stay mentally alert longer.
But there is a sobering caveat:drinking too much may make you dimmer.“People who drink more than 540 milli-litres (a little over a pint) of sake or wine a day had lower intelligence quotients than those who did not drink at all,”Hiroshi Shimokata said.“Moderation is very important.”
小題1:Which one is the topic of the passage?
A．Drinking wine in a large amount improves the IQ of old people.
B．Drinking wine in a reasonable amount raises the IQ of old people.
C．Drinking wine in moderation does good to any one.
D．Drinking wine helps improve the IQ of women.
小題2:According to the passage,which of the following is NOT wrong?
A．Every wine drinker’s IQ is 3.3 points higher than that of men who don’t drink.
B．The IQ of women drinker is 2.5 points lower than that of the non-drinking women.
C．Drinking beer and whisky cannot improve one’s IQ.
D．Drinking wine can only do good to the IQ of rich old people.
小題3:The reason why wine and sake can improve IQ is that _________.
A．wine and sake have special taste
B．wine and sake can make us excited
C．wine and sake contain substances considered to slow the ageing process
D．wine and sake contain something believed to prevent us from ageing
小題4:From the text,it seems that we can conclude _________.
A．the more wine we drink,the brighter we are
B．the less wine we drink,the brighter we are
C．drinking wine less than 540ml a day,we’ll become dimmer
D．drinking wine in moderation,we’ll become brighter

    You hear this，“No wonder you are fat．All you ever d0 is eat．”You feel sad．“I skip my breakfast and supper．I run every morning and evening．What else can I do?”
Basically you can do nothing．Your genes，not your life habits，determine your weight and your body constantly tries to maintain it．
Albert Stunkard of the University of Pennsylvania found from experiments that“80 percent of the children of two fat parents become fat，as compared with no more than 14．percent of the children of two parents of normal weight．”   
How can obese people become thinner through dieting? Well，dieting can be effective．but the health costs are great．
Jules Hirsch，a research physician at Rockefeller University，did a study of eight fat people．They were．given a liquid formula（配方）providing 600 calories a day．After more than 10 weeks，the subjects lost on average 45 kg．But after leaving the hospital，they all regained the weight．
The results were surprising：by metabolic（新陳代謝的）measurement，fat people who lost large amounts of weight seemed like they were starving．They had psychiatric problems．They dreamed of food or of breaking their diet They were anxious and depressed．Some wanted to kill themselves．They hid food in their rooms．
Researchers warn that it is possible that weight reduction doesn’t result in normal weight，but in an abnormal state lust like that of starved non．obese people．   
Thin people, however，suffer from the opposite．They have to make a great effort to gain weight  Ethan Sims of the University of Vermont got prisoners to volunteer to gain weight．In four to six months—they ate as much as they could．They succeeded in increasing their weight by 20 to 25 percent. But months after the study ended，they were back to normal weight and stayed there．
This did not mean that people are completely without hope in controlling their weight．It means that those who tend to be fat will have to constantly battle their genetic inheritance（遺傳）if they want to significantly 1ower their weight．
The findings also provide evidence for something scientists thought was true—each person has a comfortable weight range．The range might be as much as 9kg．Someone might weigh 60--69kg without too much effort．But，going above or below the natural weight range is difficult.The body resists by feeling hungry or full and changing．the metabolism to push the weight back to the range it seeks．
小題1:The story is mainly written to      。
A．point out the relations between our body and mind
B．warn us it’s extremely harmful to reduce or gain our weight
C．tell us that it’s difficult to make a significant change in our weight
D．stress that dieting 1s a recommended way to help you reach your desired weight
小題2:Jules Hirsch’s study’found that        ．
A．big weight loss could lead to mental problems
B．a person’s weight can be decided by their parents’ weight
C．only dieting cannot produce a desired result in weight reduction
D．big efforts to lose weight may result in a weight much heavier than one’s normal weight
小題3:From the text，we know that the body can still feel comfortable
A．when the weight goes up or down by 6 kg
B．when the weight goes up or down by l0 kg
C．when the weight is increased by 20 to 25 percent
D．when the weight is decreased by 20 to 25 percent
小題4:What can be inferred from the passage?
A．When it comes to weight，naturalness is the healthiest
B．Weight reduction could be both risky and painful．
C．Seek professional advice when reducing your weight．
D．There’s no hope and no point in controlling your weight．

People Born in Autumn Live Longer
People born in the autumn live longer than those born in the spring and are less likely to fall chronically ill when they are older, according to an Austrian scientist.
Using census（人口普查）data for more than one million people in Austria, Denmark and Australia, scientists at the Max Planck Institute in the northern German town of Rostock found the month of birth was related to life expectancy（預期壽命）over the age of 50. Seasonal differences in what mothers ate during pregnancy, and infections occurring at different times of the year could both have an impact on the health of a new-born baby and could influence its life expectancy in older age. “A mother giving birth in spring spends the last phase of her pregnancy in winter, when she will eat less vitamins than in summer,” said Gabriele Doblhammer, one of a team of scientists who carried out the research. “When she stops breast-feeding and starts giving her baby normal food, it’s in the hot weeks of summer when babies are prone (易于)to infections of the digestive system.” In Austria, adults born in autumn (October-December) lived about seven months longer than those born in spring (April-June), and in Denmark adults with birthdays in autumn outlived those born in spring by about four months. In the southern hemisphere, the picture was similar. Adults born in the Australian autumn—the European spring—lived about four months longer than those born in the Australian spring. The study focused on people born at the beginning of the 20th century, using death certificates and census data. Although nutrition at all times of the year has improved since then, the seasonal pattern persists, Doblhammer said.
But on the other hand, according to a study of more 40,000 people, those born in spring and summer report themselves luckier than those born in autumn or winter. Professor Richard Wise-man who led the research explained that the temperature at the time of birth might influence the development of the brain and seasonal factors make a difference as well.
小題1:The underlined word “outlived” in the text probably means ________.
A．lived out ofB．depended on
C．had a shorter life thanD．lived longer than
小題2:The census data of the following countries is used for research EXCEPT _______.
A．Germany.B．Denmark.
C．Australia.D．Austria.
小題3:What’s the main idea of this text?
A．Nutrition at all times of the year has improved since the beginning of the 20th century.
B．In Austria, adults born in autumn (October—December) lived about seven months longer than those born in spring (April—June).
C．People born in autumn live longer than those born in spring and are less likely to fall ill when they are older.
D．Babies are prone to infections of the digestive system.
小題4:Which of the following is NOT true according to the text?
A．Infections occurring at different times of the year influence the health of a new-born baby.
B．The study focused on people born in the late 20th century.
C．A mother giving birth in spring eats less vitamins during the last phase of her pregnancy in winter.
D．What mothers ate during pregnancy could have an impact on the babies’ life expectancy in older age.
小題5:The right sentence of the following is ________.
A．The month of birth was not related to life expectancy over the age of 50.
B．A mother giving birth in spring spends the last phase of her pregnancy in winter, eating more vitamins than in summer.
C．Stopping breast-feeding and starting giving babies normal food must make babies prone to get infected with the digestive system in the hot weeks of summer.
D．Adults born in the Australian autumn―the European spring―lived about four months longer than those born in the Australian spring.

June 26, 2000 — the Human Genome(基因組) Project, a great $3 billion, 15-year task aimed at drawing the genetic map of humans, is now more than 90 percent completed. The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延長) human life. But those communities and policy makers also are careful about the scientific door they are opening as the project uncovers the mysteries of life.
For the last few years, the genetic advances in the developing field of biotechnology have provides material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic code(密碼) have opened a world of possibilities for human health, as well as for the popular imagination.
While European and Japanese researchers are making rapid progress in decoding(解碼) human DNA, the leading organization for genetic research is in the United States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal diseases. Already, the Human Genome Project has become widely known and praised for finding the genes connected with terrible diseases as yet(迄今), and making progress toward separating the genes that show a sign of breast cancer or AIDS.
Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.
小題1: Why did the scientists work hard at mapping the human genome?
A．Because the human genome can destroy many illnesses.
B．Because the human genome's completion can help them get rid of many diseases.
C．Because they wanted to be better known than others.
D．Because the human genome can provide a lot of chances of work.
小題2:Which country studied the genes most rapidly in the world?
A．Japan.B．Germany.C．The United States.D．China.

Anti-bird flu contingency (意外事故) measures, including a proposal to separate poultry from humans and a series of traffic and logistics (后勤) measures will be discussed at the Legislative Council's Food Safety and Environmental Hygiene Panel meeting next month. Secretary for Health, Welfare and Food Dr York Chow says the contingency plan would come into force if an outbreak occurred near Hong Kong.
Speaking on a radio talk show this morning, Dr Chow said the separation of poultry from humans policy, which will be determined after a decision whether to set up a central slaughtering (屠宰) house or several regional ones, would be based on the demand for live chickens.
He pointed out that at present there were 30,000 live chickens imported from the Mainland and 30,000 supplied locally. If this demand persisted, there would be no central slaughtering house or wholesale point that could handle such an amount and regional slaughtering houses could be the choice.
He added that building of regional slaughtering houses took time, but stressed the need to study the views of the public and the sector before a final decision was made.
Regarding avian flu vaccination (種痘) for humans, Dr Chow said it was still being developed. He added that it may not be reliable in the case of an outbreak as records show vaccination can only offer 5% protection against a virus.
He said Hong Kong had more experience and expertise than neighbouring territories in the fight against viral outbreaks, and was willing to offer them help. He added there was no “boundary” for infectious diseases and close cooperation among different countries had to be maintained to fight against a possible outbreak.
小題1: It can be inferred from the first paragraph that ______.
A．the government is planning to take strong action to fight against bird flu
B．an outbreak which happened near Hong Kong made people very frightened
C．anti-bird flu contingency measures will come into use next month
D．Dr York Chow will organize a meeting to discuss the contingency plan
小題2:According to the passage, the best way to fight against bird flu is to ______.
A．separate poultry from humansB．set up a central slaughtering house
C．set up several regional slaughtering housesD．get avian flu vaccination
小題3:When the final decision will be made mainly depends on ______.
A．the demand for live chickensB．the views of the public
C．the advice from experts
D．the time when regional slaughtering houses will be finished
小題4:Which of the following statements isn’t Dr York Chow’s opinion?
A．Hong Kong is better at dealing with viral outbreaks than its neighbours.
B．Infectious diseases could happen in any country.
C．Other territories should ask Hong Kong for help because it has more experience.
D．Cooperation is quite necessary when danger is coming.

We have met the enemy, and he is ours. We bought him at a pet shop. When monkey-pox, a disease usually found in the African rain forest, suddenly turns up in children in the American Midwest, it’s hard not to wonder if the disease that comes from foreign animals is homing in on human beings. “Most of the infections (感染) we think of as human infections started in other animals,” says Stephen Morse, director of the Center for Public Health Preparedness at Columbia University.
It’s not just that we’re going to where the animals are; we’re also bringing them closer to us. Popular foreign pets have brought a whole new disease to this country. A strange illness killed Isaksen’s pets, and she now thinks that keeping foreign pets is a bad idea. “I don’t think it’s fair to have them as pets when we have such a limited knowledge of them,” says Isaksen.
“Laws allowing these animals to be brought in from deep forest areas without stricter control need changing,” says Peter Schantz. Monkey-pox may be the wake-up call. Researchers believe infected animals may infect their owners. We know very little about these new diseases. A new bug (病毒) may be kind at first. But it may develop into something harmful. Monkey-pox doesn’t look a major infectious disease. But it is not impossible to pass the disease from person to person.
56. We learn from Paragraph 1 that the pet sold at the shop may _________.
A. come from Columbia            B. prevent us from being infected
C. enjoy being with children         D. suffer from monkey-pox
57. Why did Isaksen advise people not to have foreign pets?
A. They attack human beings.         B. We need to study native animals.
C. They can’t live out of the rain forest.  D. We do not know much about them yet.
58. What does the phrase “the wake-up call” in Paragraph 3 most probably mean?
A. a new disease           B. a clear warning   C. a dangerous animal     D. a morning call
59. The text suggests that in the future we _______.
A. may have to fight against more new diseases   B. may easily get infected by diseases from dogs
C. should not be allowed to have pets           D. should stop buying pets from Africa
60. The last paragraph means _________.
A. we should have laws to stop having pets at home 
B. wild animals shouldn’t adopted as pets
C. laws should be passed to avoid pets’ diseases spreading 
D. people with pets should be stayed at home

Ⅲ 閱讀（共兩節(jié)。滿分40分）
第一節(jié)閱讀理解（共15小題；每小題2分，滿分30分）
閱讀下列短文，從每題所給的A、B、C和D項中，選出最佳選項，并在答題卡上將該項涂黑。
A
Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.
Proper nutrition (營養(yǎng)) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”. Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白質) , like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (維他命) and minerals. However, don't overeat. It is not helpful to be overweight.
Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality. Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (壽命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
If everybody were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.
41. According to the passage,_________.
A .we should always keep fit
B. if we were healthy, we could spend our days in doing things with less sleep
C. one can eat a lot to stay in good shape
D. one needn't take any exercise if he is healthy
42. In order to keep good health, ___________ .
A. we should eat a lot of sweets      
B. one needs a large amount of fat
C. people should eat according to the foods nutrition
D. we must try to sleep now and then
43. Eating more and sleeping less________.
A. can keep healthy                 B. is no good for you
C. gets you more energy           D. will keep your personality
44.The writer explains ________in this passage.
A. how to eat                         B. the importance of doing exercise
C. how to keep healthy             D. what to eat
45.The title of the article should be___________ .
A. Eating and Exercising           B. How Vitamins Work in Man's Body
C. Staying Healthy                   D. Sleeping Well
