Bad teeth can be painful -- and worse. They can even be deadly. Infections (感染) of the gums (牙齦) and the teeth can cause bacteria (細菌) to go into the blood system. Those bacteria can increase the chance of a heart attack and worsen the effects of other diseases. And adults are not the only ones at risk.
For example, in 2007, doctors in the Washington area said a boy died when a tooth infection spread to his brain. They said it might have been prevented had he received the dental care (牙齒保健) he needed. He was twelve years old.
Experts at the National Institutes of Health 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 the growth of bacteria and acid production in the mouth.
But dentists say a baby's gums and early teeth should be cleaned after each feeding. Use a cloth with a little warm water. Do the same if a baby is fed with a bottle. Experts say if you decide to put your baby to sleep with a bottle, only give the child 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 (琺瑯質(zhì)) , the hard surface on teeth, to help prevent holes from forming.

A．Concerns for Healthy Teeth of the Young
B．Causes of Teeth Problem

Most young people 21 some form of 22    activity.  It may be walking, cycling,or swimming, or in winter, skating, or skiing. It may be a game of some kind—football, hockey, golf or tennis. It may be mountaineering. (登山運動) Those who have a 23 for climbing high and difficult mountains are often 24 with astonishment. Why are men and women willing to 25 cold and hardship, and to take 26 on high mountains? This astonishment is caused, probably, by the 27 between mountaineering and other forms of activity 28 which men 29 their leisure (空閑的) time. Mountaineering is a sport and not a game. There are no manmade rules, 30 there are for such games as golf and football. There are, 31 rules of a different kind which would be dangerous to ignore, but it is this freedom from manmade rules 32 makes mountaineering 33 to many people. Those who climb mountains are 34 to use their own methods. If we compare mountaineering and other more familiar sports we might think that one big difference is that mountaineering is not a “team game” .We should be mistaken in this. There are , it is true, no “matches” between “teams” of climbers but when climbers are on a rock face 35 by a rope 36 which their lives may depend, there is obviously teamwork. The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical 37. A mountain climber continues to improve in skill year after year. A skier is probably past his best by the age of thirty, and most international tennis 38 are in their early twenties. 39 it is not unusual for men of fifty or sixty to climb the highest mountains in the Alps. They may take more time than younger men, but they probably climb with more skills and less waste of effort, and they certainly 40 equal enjoyment.

Malaria, the world's most widespread parasitic(寄生蟲引起的) disease, kills as many as three million people every year—almost all of whom are under five, very poor, and African. In most years, more than five hundred million cases of illness result from the disease, although exact numbers are difficult to assess because many people don't (or can't) seek care. It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment, and what they often get no longer works. In countries like Tanzania, Mozambique, and the Gambia, no family, village, hospital, or workplace can remain unaffected for long.
Malaria starts suddenly, with violent chills, which are soon followed by an intense fever and, often, headaches. As the parasites multiply, they take over the entire body. Malaria parasites live by eating the red blood cells they infect. They can also attach themselves to blood vessels in the brain. If it doesn't kill you, malaria can happen again and again for years. The disease passed on to humans by female mosquitoes infected with one of four species of parasite. Together, the mosquito and the parasite are the most deadly couple in the history of the earth—and one of the most successful. Malaria has five thousand genes, and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control. Studies show that mosquitoes are passing on the virus more frequently, and there are more outbreaks in cities with large populations. Some of the disease's spread is due to global warming.
For decades, the first-choice treatment for malaria parasites in Africa has been chloroquine, a chemical which is very cheap and easy to make. Unfortunately, in most parts of the world, malaria parasites have become resistant to it. Successful alternatives that help prevent resistance are already available, but they have been in short supply and are very expensive. If these drugs should fail, nobody knows what would come next.
小題1:According to paragraph 1, many people don't seek care because___.
A．they can remain unaffected for long
B．it is unusual to seek care
C．they are too poor
D．there are too many people suffering from the disease
小題2:People suffering from malaria___.
A．have to kill female mosquitoes
B．have ability to defend parasites
C．have their red blood cells infected

小題3:Which of the following may be the reason for the wide spread of the disease?
A．Its outbreaks in cities with large populations.
B．Its ability to pass on the virus frequently.
C．Its resistance to global warming.
D．Its ability to defend itself and resist new drugs.
小題4:It can be inferred from the passage that___.
A．no drugs have been found to treat the disease
B．the alternative treatment is not easily available to most people
C．malaria has developed its ability to resist parasites
D．nobody knows what will be the drug to treat the disease
小題5:Which of the following questions has NOT been discussed in the passage?
A．How can we know one is suffering from malaria?
B．How many people are killed by malaria each year?
C．Why are there so many people suffering from malaria?
D．What has been done to keep people unaffected for long?

“Some day, there’ll be no Americans left in the NBA,” said 12-year-old Xing Tao, who joined his school team two weeks ago after watching Yao Ming in a televised NBA game, “The players will all be Chinese, like Yao.”
To China, Yao is a home-grown superstar who helped make the world’s first basketball league closer to Chinese players. To the NBA, the 2.23-meter center offers an opening of a different sort into the world’s largest new market. Yao’s NBA first appearance against the Indiana Pacers in October reached 287 million families in the US. That game might have been a bit of a letdown to Yao’s fans: He played just 11 of the 48 minutes, had two rebounds(籃板) and got no points. Comparing that with his performance on December 19, also against Indiana, Yao won 29 points and 10 rebounds. “This was one of the most exciting games I’ve had,” Yao said after Houston’s 95-83 victory. The NBA has to be excited about his on-count success. In all his games, he’s averaging 12.7 points and 7.7 rebounds, quite good for a new star. “Yao Ming has brought the NBA closer to the Chinese,” said NBA spokeswoman Cheong Sau Ching, “That makes the dream seem practical for other people in China and proud to be Chinese.”
The 22-year-old Yao is not the country’s first player in the NBA: Wang Zhizhi broke down the Dallas Mavericks in November 2003. But Yao’s combination of modesty and skills make him a favorite back home.
小題1:What’s the direct reason for Xing Tao to join the school basketball team?
A. He watched an NBA game
B. He liked basketball.
C. He hoped to play for the NBA.
D. He had dream that he would become a basketball star.
小題2:How many points did Yao Ming win in his first game in the NBA?
A．zeroB．twoC．29D．10
小題3:What does the word “l(fā)etdown” in line 4, Paragraph 2 mean?
A．failureB．surpriseC．disappointment D．sadness.
小題4:Why does Yao Ming win more popularity than Wang Zhizhi at home?
A．He is modest and performs excellently.
B．He is too kind to others.
C．More and more Chinese people like to watch his games.
D．He is very modest but proud.
小題5:What’s the main idea of this passage?
A. Middle school students want to play basketball
B. Yao Ming makes NBA closer to China.
C. There’ll be no Americans left in the NBA
D. There are many new stars from China in the NBA.

Most American children eat potatoes every day, but they don't know which part of potato is most nourishing(有營養(yǎng)的).Take a sharp knife and cut a very thin slice(薄片) from it and hold it to the light, and you will see that the potato has skin, an outside rim(邊緣) and the inner part. The outside rim which is right under the skin is most nutritious.But this part is often thrown away with the skin. Even the skin itself is better for food than the inside. When eating a cooked potato, if you choose the inside and leave the outside, you are wasting the best part of it. If you can’t eat the whole potato, it is better to eat the outside rim and leave the inner part.
小題1:A potato has _________.
A．one part onlyB．two partsC．three partsD．four parts
小題2:The best part of the potato is the _________.
A．middleB．skinC．outside rimD．inside

Remember how great exercise was when you were a little kid? Back then，racing around the playground or skipping rope for hours，you weren't thinking fitness，you were thinking entertainment．But in this age of high-tech home equipment and underused(未充分利用的)gym memberships，the simple joy of jumping rope has been forgotten．Rediscovering it will give you a total-body exercise you can find．
Although considered an excellent form of exercise，jumping rope has never gained widespread acceptance because of two fundamental reasons．First，most people recognize jumping rope as an excellent form of cardiovascular (心血管的) exercise，but they also believe that it is simply too difficult．In other words，they don't think they'll be able to continue jumping for the near 20 minutes that it takes to achieve a beneficial physical result．Second, many view it as somewhat boring and too repetitive-not as something fun or enjoyable．
As a matter of fact，jumping rope can be great fun if you find a proper way to practise it．Instead of doing the usual two-foot bounce over and over again，people good at rope-jumping often change their pattern every 10 or 20 jumps．A single bounce，a double bounce，a skip，a knee-up，side swings，as well as a variety of other easy-to-learn free-style rope-jumping．
Now researchers are learning that jumping rope also prepares the brain for learning．It is an exercise allowing both brain hemispheres(半球)to perform in parallel(并行地)to each other．In short，jumping rope can be a life-long activity requiring little equipment，time and space，yet leading to a much healthier life．
小題1:From the first paragraph we learn that_______ ．
A．a(chǎn)ll people now have more advanced equipment
B．jumping rope has disappeared from people's memories
C．racing around the playground was preferred
D．people now like to have exercise in a gym
小題2:Rope jumping has not spread widely because_______ ．
A．it benefits the cardiovascular system
B．it requires little equipment，time and space
C．it is neither easy nor enjoyable
D．it is considered boring
小題3:The first sentence in the 3rd paragraph implies_____ ．
A．there are many ways to follow
B．the usual way should not be used
C．the easiest way is always the best
D．there is only one proper way to follow
小題4:According to the researchers, jumping rope _____.
A．only prepares the brain for learning.
B．is suitable for students only
C．helps both brain hemispheres work together
D．can be dangerous for old people
小題5:What is the author's attitude towards rope jumping?
A．He is arguing against it.B．He is sitting on the fence of it.
C．He is in favor of it.D．He is not clear about it.

Researchers in the United States have developed the first wirelessly controlled device that can supply a drug directly into the body. A small chip is implanted (植入) under the skin. It contains the medicine, which it releases at preset times. The developers say the device could improve the lives of millions of people who take medicine for long-term illnesses. A company called Microchips began developing the device about fifteen years ago. Last month, the company released the results of its first successful tests in humans. The tests took place in Denmark with seven women with osteoporosis（骨質(zhì)疏松癥）.
Osteoporosis causes bones to become weak and break easily. The disorder is common among older people especially women. Many patients have to give themselves daily injection（注射）of medicine. One type of treatment requires injections for two years. The patients stop taking the medicine because of the pain and stress of the injections. As a result, only twenty-five percent of the patients will go through the entire twenty-four months of treatment.
The microchip is a few centimeters long. It has small sections and each section holds a single dose（單次劑量）of medicine. The device has to be programmed with the times to release the drug. Doctors will be able to reprogram the device from a computer or even a cell phone.
For osteoporosis, the physician will program the device, and the device has the ability to release a dose at a given time, every single day. For other diseases, where the physician may want to change the dosing schedule, they will have the ability to wirelessly reprogram that dosing schedule.
The seven women in the study were ages of sixty-five to seventy. The researchers say the implants were just as effective as daily injections. And they say the medicine amounts were more exact than patients often give themselves.
小題1:The best title for the passage should be ______.
A．A New Company Called Microchips
B．A New Way to Take Medicine Every Day
C．Good News for Women with Osteoporosis
D．Taking Medicine, with Microchip under Skin
小題2:What does the underlined word “released” in paragraph 1 mean?
A．Announced.B．Planned.C．Got rid of.D．Caught hold of.
小題3:We can learn from Paragraph 2 that ______.
A．older people especially men easily develop steoporosis
B．bones’ becoming weak and breaking easily causes steoporosis
C．a(chǎn) quarter of the patients will go through the entire two years of treatment
D．pain and stress of the injections lead all patients to stop taking medicine
小題4:What advantages does the microchip have?
a. effective implants  
b. less exact medicine amounts
c. purposely—changed dosing schedule
d. only one centimeter long and having small sections
e. improving the lives of millions of people
A．a(chǎn), b, cB．c, d, eC．a(chǎn), c, eD．b, c, d

Why do men live a shorter life than women? The latest research indicates that men’s hearts going into a rapid decline when they reach middle age could be the cause.
The research of ageing on the heart has shown that women’s longevity may be linked to the fact that their hearts do not lose much pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 20 and 70 years of age,” said the head of the study, Samantha of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells which make it beat.Between the ages of 20 and 70, one-third of those cells die and are not replaced in men ,” said Samantha.“This is part of the ageing process.”
What amazes scientists is that the female heart suffers very little loss of these cells.A healthy 70-year-old woman’s heart could work almost as perfectly as a 20-year-old one’s.
“This gender （性別）difference might give the reason why men live shorter than women,”said Samantha.They studied over 250 healthy men and women between the ages of 17 and 80, who are mainly healthy persons so as to reduce the influence of disease.“The team has yet to think about why ageing suffers a greater loss on the male heart,” said Samantha.
But there is also good news -- men can enjoy the health of their hearts with regular exercise.Samantha stressed that women should also take regular exercise to stop their leg muscles getting weaker as they age.
小題1:The underlined word “l(fā)ongevity” in the second paragraph means “________”.
A．healthB．long lifeC．a(chǎn)geingD．effect
小題2:The text mainly talks about ________.
A．men’s heart cellsB．women’s ageing process
C．the gender differenceD．hearts and long life
小題3:According to the text, the UK scientists have known that ________.
A．men have fewer cells than women when they are born
B．women can produce the cells that make the heart beat
C．the female heart suffers less loss of the cells with age
D．women will never suffer the loss of pumping power with age
小題4:If you want to live a long life, you should ________.
A．enable your heart to beat much faster
B．think about the reason for ageing
C．take regular exercise to keep your heart healthy
D．stop your cells from being lost

There is an English saying :“l(fā)aughter is best medicine .”Until recently ,few people took the saying seriously .Now however ,doctors have begun to look into laughter and the effects it has on the human body .They have found that laughter really can improve people’s health .
Tests were carried out to study the effects of laughter on the body .People watched funny films while doctors checked their hearts ,blood pressure ,breathing and muscles .It was found that laughter had similar effects to physical exercise .It increases blood pressure ,the heart beating and breathing ; it also works several groups of muscles in the face ,the stomach ,and even the feet .If laughter exercises the body ,it must be beneficial .
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body .In one experiment doctors produced pain in groups of students who listened to different radio programmes .The group that tolerated(忍耐)the pain for the longest time was the groups which listened to a funny programme .The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain .
As a result of these discoveries ,some doctors in the United States now hold laughter clinics ,in which they help to improve their patients’ condition by encouraging them to laugh .They have found that even if their patients do not really feel like laughing ,making them smile is enough to produce beneficial effects similar to those caused by laughter .
