People around the world drink about 180 billion liters of soda a year. That translates to more than 29 liters per person. Experts say the amount of carbonated soft drinks we consume(消費(fèi)) is growing. New research from the American Heart Association finds that drinking soda, even diet soda, may significantly increase your risk for heart disease. Dr. Ramachandran Vasan led the study. "Drinking just one or more sodas a day may not be as innocuous as people think."
In a large study of 9,000 people, doctors discovered that those who drank one or more sodas a day had a 30% increased risk for obesity(肥胖), a 25% increase in the risk for abnormal(非正常的) blood sugar levels, and a 32% increase in the odds of having low levels of good cholesterol(膽固醇).
All of these factors increase the risk for heart disease. And there was no difference in the results for those who drank diet soda over regular soda. It’s something that surprised even the researchers.
Critics of the study say diet soda may not be the cause of increased risk of heart disease. Connie Diekman is president of the American Dietetic Association. "It does not conclusively say that this will cause that."
In other words, it could be that unhealthy people like soda. Dr. Vasan found those who drink soda generally tend to have greater caloric intake. They eat more saturated fat and trans fats. They also eat less fiber and exercise less. Diet soda drinkers may also share this unhealthy lifestyle. Dr. Vasan agrees that the link he found between heart disease risk and diet soda needs additional study.
【小題1】 What does the underlined word “innocuous” in the first paragraph probably mean?

A．popular. B．harmless. C．effective. D．risky.
【小題2】 According to the study, which of the following is true?
A．Only people who overdrink sodas have high risk for heart disease.
B．In the study, about one quarter of people have high blood level.
C．Both regular and diet sodas can probably increase the risk for heart disease.
D．Dr. Vasan is the leader of the American Heart Association.
【小題3】 What can be inferred from the passage above?
A．All the experts agree with the results of the study.
B．Sodas of any kind are certain to increase the risk for heart disease.
C．People have expected the results of the research.
D．More studies are needed to prove the results.
【小題4】How does the writer present the passage?
A．By comparing opinions. B．By giving advice.
C．By showing facts. D．By discussing information.

Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda（大熊貓）eats only one particular type of bamboo（竹子）. Other animals eat only one type of food even when given the choice. A kind of white butterfly（蝴蝶）will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet（多樣化飲食）. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.
【小題1】We can infer from the text that humans and animals _________.

A．depend on one sense in choosing food
B．a(chǎn)re not satisfied with their food
C．choose food in similar ways
D．eat entirely different food
【小題2】Which of the following eats only one type of food?
A．The white butterfly. B．The small bird.
C．The bear. D．The fox.
【小題3】Certain animals change their choice of food when ___________.
A．the season changes
B．the food color changes
C．they move to different places
D．they are attracted by different smells
【小題4】We can learn from the last paragraph that __________.
A．food is chosen for a good reason
B．French and British food is good
C．some people have few choices of food
D．some people care little about healthy diet

Bad teeth can be painful and even be deadly. Infections of the gums(牙齦) and teeth can release bacteria into the blood system. Those bacteria can increase the chance of a heart attack or stroke and worsen the effects of other diseases. And adults are not the only ones at risk. For example, a 12­year­old boy died when a tooth infection spread to his brain in 2007 in Washington. Experts said it might have been prevented had he received the dental care he needed.
Experts say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. But dentists say a baby's gums and early teeth should be cleaned after each feeding by using a cloth with a little warm water. Experts say if you decide to put your baby to sleep with a bottle, give only water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently. The use of fluoride(氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel(釉質(zhì)), the hard surface on teeth, to help prevent holes from forming.
But young children often swallow toothpaste when they brush their teeth. The American Academy of Pediatric Dentistry notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully watched when they brush their teeth. And only a small amount of fluoridated toothpaste, the size of a pea, should be used.
Parents often wonder what effect finger sucking might have on their baby's teeth. Dental experts generally agree that this is fine early in life. Most children stop sucking their fingers by the age of four. If it continues, experts advise parents to talk to their children's dentists or doctors. Because it could interfere_with the correct development of permanent teeth.
Dentists say children should have their first dental visit at least by the time they are one year old. They say babies should be examined when their first teeth appear—usually at around six months.
【小題1】According to the passage，what is the function of fluoride?

A．Making the surface on teeth much cleaner.
B．Protecting gums from being infected.
C．Keeping holes on teeth from forming.
D．Slowing down bacterial growth and acid production.
【小題2】The underlined phrase “interfere with” in Para.5 probably means “________”．
A．do harm to B．a(chǎn)ccount for
C．contribute to D．stand for
【小題3】What is the purpose of the author in writing the passage?
A．To warn us of the deadly infections of gums and teeth.
B．To introduce the advantages of fluoridated toothpaste.
C．To draw our attention to the dental care of young children.
D．To present the research results about dental care.

Cell phones:  is there a cancer link?
Could your cell phone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and Wi-Fi could be responsible for a range of illnesses, from rashes to brain tumors.
Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there’s a greater than 95 percent chance that power lines can cause childhood leukemia(白血病). Also there’s a greater than 90 percent chance that cell phones can cause brain tumors. “It’s apparent now that there’s a real risk, ” said Carpenter.
But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology(流行病學(xué)) at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. “I don’t support warning labels for cell phones, ” said Linet. “We don’t have the evidence that there’s much danger. ”
Studies so far suggest a weak connection between EMFs(電磁場(chǎng)) and illness— so weak that it might not exist at all. A multinational investigation of cell phones and brain cancer, in 13 countries outside the US, has been underway for several years. It’s funded in part by the European Union, in part by a cell phone industry group. The final report should come out later this year, but data so far don’t suggest a strong link between cell phone use and cancer risk.
【小題1】From the passage we can learn that some people are worried because _______.

A．they have evidence that the use of cell phones can lead to cancer
B．they make a fuss over cell phone use
C．some experts have given a warning
D．cell phones are responsible for brain tumors
【小題2】By saying “I don’t support warning labels for cell phones, ” Dr Martha Linet has the idea that _______.
A．the worrying is unnecessary
B．cancer-warning labels should be on cell phones
C．there is a link between cell phones and cancer
D．cell phones have nothing to do with cancer
【小題3】Which of the following best describes the attitude of the author towards the debate?
A．Optimistic. B．Objective.
C．Opposite. D．Casual. ]

Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a cure.
At first, Eijkman thought some kind of germ (細(xì)菌) caused beri-beri. He raised some chickens. He didn’t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精煉米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins (維生素). The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.
Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don’t, they can also take vitamin pills.
【小題1】The underlined word “cure” in Paragraph 1 probably means ______.

A．a(chǎn) medical treatment B．a(chǎn) kind of vitamin C．a(chǎn) kind of germ D．a(chǎn) kind of rice
【小題2】Christian Eijkman went to the island of Java to ______.
A．spend his holiday
B．find ways to grow better crops
C．do some research about the island
D．help the Javanese with their illness
【小題3】Why did Christian Eijkman raise some chickens?
A．To eat them.
B．To carry out his experiments.
C．To give the Javanese a surprise.
D．To make money by selling them.
【小題4】If a person doesn’t get enough vitamins in his diet, he’d better ______.
A．eat more rice B．eat more meat C．eat some chicken D．eat vitamin pills
【小題5】We can learn from the passage that ______.
A．beri-beri was caused by chickens
B．the Javanese didn’t like vitamins
C．Christian Eijkman’s experiment was successful
D．the Javanese’s disease was caused by a kind of germ
