閱讀下列短文，從每題所給的四個選項中(A、B、C和 D)中，選出最佳選項，并在答題卡上將該項涂黑。
A
Most of us feel upset if we miss just one meal, and if we try to go without food for 12 hours we would really be uncomfortable. But there are some people who seem able to “fast” for very long periods.
Various records are claimed for long fast, but in most cases there is no medical proof and so the records are doubtful. One South African woman claimed that she lived for 102 days on nothinig but water and soda water.
There are great differences among living things in the ability to survive without food. For example , a tick（扁虱）, which lives on animals, may survive a whole year. Warm-blooded animals use up their stores of food in the body more quickly.
In fact, the smaller and more active the animal, the more quickly it uses up its reserves. A small bird starves to death in about five days, a dog in about twenty. In general, we can say that a warm-blooded creature will die when it has lost about half its normal weight.
This matter of weight is important. Man and other creatures live in a state of metabolic equiplibrium（新陳代謝的平衡）which means maintaining the body weight once a certain point has been reached. This regulation of body weight is done by thirst, hunger, and appetite.
When your blood lacks nutritional materials, this registers（記錄）in the hunger center of the brain and you feel “hungry”. The body is crying out for any kind of fuel(food). And it is our appetite that sees to it hat we chooose a mixed diet, which is the kind the body needs.
小題1:According to this passage, a man will die _________.
A．when a certain point in losing weight has been reached.
B．when his blood lacks nutritional material
C．when his normal weight is lost
D．when he goes without food for more than 12 hours
小題2:The word “fast” in Paragraph 1 can best be replaced by ________.
A．eat no foodB．live merely on water and soda water
C．live on nothingD．remains alive for a long time without food
小題3:A tick can survive much longer than a bird because ________.
A．a(chǎn) tick lives on animalsB．a(chǎn) tick is much smaller
C．a(chǎn) bird is more activeD．both B and C
小題4:A person feels hungry _________.
A．if he doesn’t choose a mixed diet
B．because his body cries out for food
C．when soemthing is wrong with regulation of body weight
D．if there are not enough nutritional in his blood
小題5:From the passage we can infer that the author ________.
A．believes the South African woman very firmly
B．does not believe the South African woman at all
C．is not certain whether the South African woman’s claim was true.
D．is doubtful whether there was such a South African woman
小題1:A
小題2:A
小題3:C
小題4:D
小題5:C

小題1:由第四段最后一句話得答案為A.D項從第一段第二句看不對。
小題2:通過前一句中without food for 12 hours 得出

It is easy for many people to catch a cold in the springtime or fall. It makes us wonder if scientists can send a man to the moon, why can’t they find a cure for the common cold? The answer is easy. There are actually hundreds of kinds of cold viruses out there. You never know which one you will get, so there isn’t a cure for each one.
When a virus attacks your body, your body works hard to get rid of it. Blood rushes to your nose and cause a block in it. You feel terrible because you can’t breathe well, but your body is actually eating the virus. Your temperature goes up and you get a fever, but the heat of your body is killing the virus. You also have a runny nose to stop the virus from getting into your cells. You may feel very uncomfortable, but actually your wonderful body is doing everything it can to kill the cold.
Different people do different things to deal with colds. In the United States and some other countries, for example, people might eat chicken soup to make themselves feel better. Some people take hot baths and drink warm liquids. Other people take medicine to stop various symptoms (癥狀) of colds.
There is one interesting thing to note —some scientists say taking medicines when you have a cold is actually bad for you. The virus stays in you longer because your body doesn’t have a way to fight it and kill it. Bodies can do an amazing job on their own. There is a joke, however, on taking medicine when you have a cold. It goes like this:
It takes about one week to get over a cold if you don’t take medicine, but it takes only seven days to get over a cold if you take medicine.

In 2030, 42 percent of American adults will be obese, and about one-quarter of that group will be severely obese, a condition that shortens life and wastes large medical expenses, a new study predicts.
Obesity related ailments — diabetes, heart disease, kidney failure — consume at least 9 percent of health-care spending the United States. Some researchers believe the cost may be twice that estimate. Total health spending is about $2.6 trillion a year.
In 2030, 42 percent of people are projected to be obese, and 11 percent severely obese. Obesity is a body mass index , which suggests 85 kg for someone 1.67 meters tall. Severe obesity is 112 kg for someone that height.
Obesity is rising in higher-income men. Severe obesity is increasing in both sexes. It was 6.2 percent in women in 1999 and 8.1 percent in 2010. For men, it was 3.1 percent in 1999 and 4.4 percent in 2010.
It is believed that the obesity rate is closely related to the following factors: the price of gasoline, which discourages walking when it is low; access to the Internet (and other technologies), which encourages long periods of sitting still; and restaurants per 10,000 people, which increases eating out and weight gain when the number goes up.
Urgent measures must be taken to inspire people to exercise more and educate people about better eating habits before too many people will be suffering from being . obese.
小題1:The word “ailments” in the second paragraph is equal to _______.
A．DiabetesB．Heart diseaseC．Kidney failureD．Diseases
小題2:If a man aged 35 is about 1.65 meters tall and weighs 65 kg, he is

Eating a diet high in processed food(加工食品)increases the risk of depression，research suggests．What's more，peopie who ate plenty of vegetables，fruit and fish actually had a lower risk of depression，the University College London team found．
Data on diet among 3，500 middle-aged civil servants(公務(wù)員)were compared with their emotional state five years later，a British journal reported．They split the participants into two types of diet--those who ate a diet largely based on whole food，which inc!udes lots of fruit， vegetables and fish，and those who ate a mainly processed food diet，such as sweetened desserts，fried food，processed meat，refined grains and high fat dairy products After accounting for factors such as gender，age，education，physical activity，smoking habits and chronic(慢性的) diseases，they found a significant difference in the future depression risk with the different diets．
Those who ate the most wholefood had a 26％ lower risk of future depression than those who ate the least wholefood．By contrast，people with a diet high in processed food had a 58％ higher risk of depression than those who ate a diet low in processed foods．
Study author Dr. Archana SinghManoux pointed out there was a chance the finding could be explained by fl lifestyle factor they had not accounted for．
There was a paper showing a Mediterranean diet was associated with a lower risk of depression，but the problem with that is if you live in Britain，the likelihood(可能性)of you eating a Mediterranean diet is not very high．
Dr．Andrew McCulloeh，chief executive of the Mental Health Foundation，said，this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health．
He added people's diets were becoming increasingly unhealthy．The UK population is consuming less nutritious，fresh produce and more saturated(含飽和脂肪酸的)fats and sugars．
小題1:The text is mainly about         .
A．the increasingly unhealthy diet of the UK population

A．It is difficult for most British people to have a Mediterranean diet．
B．The Mediterranean diet is the most healthy in the world．
C．Many studies have been done on the Mediterranean diet before．

Forget chip fat, sugar cane or rapeseed oil — the latest source of biofuel could be watermelons. Scientists have discovered that the fruit is a great source of sugar that can be readily distilled (蒸餾) into alcohol to power cars and farm machinery.
And sellers reject 360,000 tons of “substandard” fruit every year in America alone which could be used as an economical way to make fuel. The waste from US growers could produce nearly two million gallons (nine million litres) of biofuel per year.
In the study, researchers at the United States Department of Agriculture set out to determine the biofuel potential of juice from rejected watermelons —those not sold due to cosmetic imperfections, and currently ploughed back into the field. About a fifth of each yearly watermelon crop is left in the field because of surface blemishes (瑕疵) or because they are misshapen.
Dr. Wayne Fish, who led the team, found that 50 percent of the fruit was fermentable (可發(fā)酵的) into alcohol which could provide valuable fuel.
“We’ve shown that the juice of these watermelons is a source of readily fermentable sugars, representing an unexploited raw material for alcohol biofuel production,” he said.
The study, published in the journal Biotechnology for Biofuels, discovered that watermelons could produce around 20 gallons of fuel per acre from fruit that otherwise would go to waste.
Production of biofuels has been targeted by Western governments as a way to support renewable energy targets.
The European Union has a target for 2010 that 5.75 percent of transport fuels should come from biological sources, but the target is unlikely to be met.
The British government’s Renewable Transport Fuel Obligation requires five percent of the fuel sold at the pump by 2010 to be biofuel.
小題1:The passage mainly tells us ______.
A．watermelon juice will be the largest source of renewable energy
B．the advantages of fuel made from watermelons
C．Western countries aim at producing biofuels
D．watermelons could be used to make fuel
小題2: It can be learned from the text that ______.
A．a(chǎn)bout two gallons of fuel could be made from rejected fruit per acre
B．sellers in the world throw away 360,000 tons of watermelons every year
C．half of the watermelons were fermentable into alcohol to provide energy
D．five percent of fuel is required to be biofuel from watermelons by 2010 in Britain
小題3:The underlined word “cosmetic” in Paragraph 3 probably means ______.
A．freshB．sweetC．surfaceD．inside
小題4:We can infer from the passage that ______.
A．it will cost a lot to make biofuel from watermelons
B．Western countries are engaged in biofuel study but still have a long way to go
C．watermelon juice has been used as a source of sugars to produce alcohol biofuel
D．the European Union is likely to meet its target of transport fuels from biological sources

Coffee experts are willing to pay large sums of money for high-quality coffee beans. The high-end beans, such as Kona or Blue Mountain, are known to cost extraordinary sums of money. Then there is Kopi Lowak (translated as “Civet Coffee”), the world’s most expensive coffee, which sells for as much as US $50 per quarter-pound.
This isn’t particularly surprising, because approximately 500 pounds a year of Kopi Lowak make up the entire world supply. What is surprising is why this particular coffee is so rare. In fact, it’s not the plants that are rare. It’s the civet droppings. That’s right, the civet droppings—the body waste of the palm civet. Coffee beans aren’t Kopi Lowak until they’ve been digested(消化) and come out in the body waste of the palm civet.
Palm civets are tree-dwelling, raccoon-like little animals, native to Southeast Asia and the Indonesian islands. They also have a love for coffee cherries. According to Kopi Lowak suppliers, palm civets eat the fruit whole, but only digest the outer fruit, leaving the beans intact(完好無損). While the beans are not destroyed, they undergo a transformation in the animal’s body. A chemical substance in the digestive system of the palm civet causes some changes to the beans to give them a unique flavor(味道). However, this is not the only explanation why coffee beans retrieved from civet droppings have a special flavor all their own. Another possible reason is that palm civets have an unfailing instinct for picking the coffee cherries at the peak of their ripeness.
Kopi Lowak is reported to have a character in taste unlike any other coffee, complex with caramel undertones and an earthy flavor. Currently, most of the world’s supply of Kopi Lowak is sold in Japan, though a few US markets are also starting to stock up on Kopi Lowak.
小題1:What does “This” in the second paragraph refer to?
A．Civet Coffee.B．Blue Mountain coffee.
C．The high price of Kopi Lowak.D．The unique taste of Kona.
小題2:Why is Kopi Lowak expensive?
A．There is a very limited supply of the beans.
B．The coffee trees that grow the beans are scarce.
C．It takes a long time for the coffee beans to ripen.
D．Only a few experts know how to produce the beans.
小題3:What is the main point discussed in the third paragraph?
A．Why palm civets like the coffee beans.
B．Where Kopi Lowak is mainly harvested.
C．What chemicals are found in the civet’s digestive system.
D．How palm civets change coffee fruit to Kopi Lowak beans.
小題4:Which of the following statements is true, according to the passage?
A．Little palm civets eat only the outer layer of the coffee cherries.
B．Palm civets somehow know the right time when the coffee fruit ripens.
C．Kopi Lowak is most popular in Southeast Asia and the Indonesian islands.
D．Kona and Blue Mountain are the most expensive coffees but only of average quality.

Dr. Glenn Tisman, a cancer specialist, knew his young neighbor, Ray Bateman, had an unusual mind. But he had no idea at the time that 12 - year – old Ray had the ability to become his partner in cancer research.
Ray’s parents remembered that at age four, Ray surprised them by fixing a broken vacuum cleaner（吸塵器）. When he was ten, he speedily constructed the family color television from a kit. Later, he succeeded in assembling（組裝） a complex stereo system after two experts had failed to do the job.
When Ray was ten, he convinced his parents to buy him a computer. In a short time, Ray was able to do amazing things with the computer. Ray shared his enthusiasm for computers with Dr. Tisman, who used a computer for his research. The two discussed computers and medicine frequently. Amazingly, Ray understood the biology and chemistry related to Dr. Tisman’s medical research without any previous instruction.
Ray then worked with Dr. Tisman after school. He helped conduct research with the equipment and kept it in working order. The purpose of the research was to test the effectiveness of mixing an old cancer drug with certain vitamins. Ray analyzed patient test results by computer, while Dr. Tisman handled all patient contact. Together, they came up with solid research that helped advance cancer treatment.
In 1988, 14 - year - old Ray went with Dr. Tisman to a meeting of the American Federation for Clinical Research（AFCR）, where Ray presented their initial research findings. Using terminology（術(shù)語） beyond the grasp of most kids his age, Ray told the scientists how the new drug mixture caused fewer and milder side effects for cancer patients.
A year later, Ray returned to the meeting to update the findings of his and Dr. Tisman’s research. By then, he had become well - known for his devotion to finding cures for sick patients. Stories about him appeared in hundred of newspapers around the world. He appeared on television newscasts and talk shows.
Ray continued to spend most free hours working with Dr. Tisman. The two began studying the effects of vitamins on babies inside the womb（子宮）. However, Ray’s main interest remained cancer treatment, and he continues his research today.
