Lack of exercise is considered a risk factor for cancer. There is considerable evidence that inactivity is connected with increased risk for lung cancer, breast cancer, etc.
In the Aerobics Center Longitudinal Study, more than 32,000 people (25,000 men and 7,000 women) were given a preventive medical examination that included a machine exercise test to measure physical fitness. They were given a physical fitness score, with one being the lowest and five being the highest fitness level. Then these people were followed for an average of 8 years. During this time, 179 men and 44 women died of cancer.
Data from the Aerobics Center Longitudinal Study show people have lower rates of cancer with higher levels of physical fitness. Studies from the Cooper Institute for Aerobics Research in Dallas suggest that men with high fitness levels are less likely to die of cancer.
The Aerobics Center Longitudinal Study also found that fitness level was more important than weight in predicting longevity (長壽). While results showed that fitness and normal weight are the ideal combination, researchers found that men who were fat but performed well in the machine performance had just a slightly increased all-cause death rate, including cancer, compared to the more slim men. The fat, but fit, men particularly lived longer than the slim, but flabby (肌肉松弛的), men.
These statistics called for a warning to the overweight: The first health goal for the overweight should be to become as fit as possible at their current weight.
67. 小題1:The text mainly talks about________.
A．the effect of exercise on reducing chances of cancer
B．how to lose weight effectively
C．different ways to keep slim
D．fat men live longer than slim ones
68. 小題2:What’s Paragraph 2 mainly about?
A．The study on the life of the overweight.
B．The study on the relationship between taking exercise and cancer.
C．The study on the ways of losing weight.
D．The study on the effects of machine exercise.
69. 小題3:Which of the following is NOT true according to Paragraph 4?
A．Fitness levels have more effects than weight on people’s longevity.
B．A man who is fit and has normal weight is most likely to live longer.
C．Slim men are more likely to live longer.
D．Fat people who like exercising are also likely to live longer.
70. 小題4:The author thinks the most important thing for the overweight is to ______.
A．increase their fitness levelsB．choose to eat vegetables
C．be on a dietD．a(chǎn)sk for help from doctors

小題1:A

Glaucoma（青光眼）is a major cause of blindness around the world, especially in developing countries. The World Health Organization says glaucoma is a greater public health challenge than cataracts（白內(nèi)障）, because the blindness caused by the latter can be cured after operations.
Glaucoma is a disease that makes people around the world lose their sight, and they usually don’t even know they have the disease until it has permanently destroyed at least 40 percent of their sight. The process is usually so painless and subtle（不明顯的）, so people don't notice it. Actually, the simplest medical test can discover it.
“It is the leading cause of blindness in the United States. In Hispanics and in African-Americans, it’s the second leading cause of blindness and so is the case in the Chinese and Indians.” said Dr. Alan Robin, a specialist in treating glaucoma. “The glaucoma we see in sub-Saharan Africa is a much more aggressive blinding disease than the glaucoma we see in Americans or even African- Americans in-the United States.” he said．     ．
Dr. Eric Fleischer also sees these differences at Medstar Washington Hospital Center. “Pretty much anybody who has ancestors in Africa has an increased chance of developing glaucoma.” Age is another thing that may lead to glaucoma, although people of all ages can get it.
Glaucoma is a group of diseases that commonly produce pressure in the eye. An eye is sort of like a watch. And behind the face of the watch, liquid is made. It goes through your pupil（瞳孔）and into the front of the watch between the face and the crystal．There's an area around the edge of the watch that drains（使排出）the liquid. When that drain is blocked, the liquid can't leave the eye as fast as it is produced. The rising pressure within the eye damages and eventually kills the optic（視覺的） nerve. The result is blindness.
Fortunately, if caught early, glaucoma can be controlled. Glaucoma is not curable. But as  researchers worldwide lean more about it, they grow more hopeful that glaucoma can one day be cured or even prevented.
小題1:In which country is glaucoma the biggest danger to people’s sight?
A．In ChinaB．In IndiaC．In the USAD．In Japan
小題2:What do the underlined words “these differences”（in Para 4 ）refer to?
A．The differences in regions（地區(qū)）B．The cultural differences
C．The differences in ageD．The physical differences
小題3:From the passage, we can learn that,            .
A．It is hard for medical tests to discover glaucoma
B．People in developed countries hardly develop glaucoma
C．Glaucoma only causes blindness among old people
D．The research on glaucoma is still going on worldwide

Hearing plays an important part in our everyday life, but few of us take the steps we need to protect our hearing.
It is easy to see how your hearing is under assault in today’s world. There are so many things to hear, and so many new instruments, like iPods and headphones, which can harm your hearing if used improperly. Keeping the volume(音量)to a reasonable level on an iPod or other portable listening instruments is one of the most important ways to protect your hearing. Another great way to keep your hearing protected is to avoid loud noises whenever possible. There are many loud noises from power tools to machinery, and it is important to avoid these noises as often as possible. When it is not possible to avoid them, keep your hearing protected by using earplugs(耳機).
If you think your hearing may have already been damaged by modern technology, it is important to have your hearing tested by a physician. Only such a professional will be able to measure your level of hearing loss and help you find the best solution to your hearing problem.
For those with hearing issues, the choices have never been greater. There are many excellent hearing aids on the market. Having a hearing aid can be a perfect choice for the young and the old alike, and many people who swore they would never wear a hearing aid find that they love the convenience and quality these instruments represent.
Never let an unimportant thing like vanity(虛榮) get in the way of treating a hearing problem. These days there are hearing aids that are nearly invisible to the naked eye, including a number of models that fit completely inside the ear. If you believe you may be experiencing a problem with your hearing, it is important to have it checked out, and to take the right measures to protect your ears. In many cases, this treatment will be as simple as wearing earplugs. Taking care of your ears is of great importance. After all, you only get one set of ears.                      
小題1:The second paragraph mainly talks about_____.
A．the causes of hearing loss
B．the importance of hearing
C．how to cure hearing problems
D．how to protect your hearing
小題2:The underlined phrase “under assault” in Paragraph 2 most probably means_____.
A．under consideration
B．under protection
C．under attack
D．under treatment
小題3:All the following factors may cause hearing problems EXCEPT_____.
A．using iPods improperly
B．listening to MP3 at full volume

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.

D
Parties, iPods, concerts, movies, TV shows, video games, traffic. All of these things of the modern world make life entertaining and enjoyable. But our 21st-century lifestyle is also loud and, if we don’t take notice, it can have an effect on our hearing.
Most teenagers don’t think about hearing loss. But if you experience any of the following symptoms（癥狀）, you may already be hearing damaged: you make efforts to hear normal talk, you have to turn up the TV or radio so high that others complain, you watch other people’s expressions to understand what they are saying, you ask people to repeat themselves, you misunderstand what people are saying or you hear ringing in your ears.
iPods and other MP3 players are as common as the clothes you wear, and just as fashionable. But if you turn up an iPod to more than 60 percent of its maximum volume（最大音量）, and listen to music for more than an hour, you are asking for trouble. And, it does not matter if the music you play is classical, rock or heavy metal.
Some researchers find that young people who break the so-called 60-percent/60-minute rule in listening to iPods are at the risk of suffering hearing loss.
Why is an iPod dangerous? With ear buds placed directly in the ear canal and high-volume music played over a long period of time, it’s like working in a loud factory all day, being a maintenance（修理）person under a jet airplane or using a jackhammer（手提鉆）on a building site.
Similarly, iPod music can cause a short time or permanent（永久的）hearing damage. A loud iPod can cause a ruptured（破裂的）eardrum and, over time, may cause permanent damage to the tiny hairs in the inner ear. If these tiny hairs are damaged, they cannot effectively send sounds to the auditory nerves（聽覺神經(jīng)）that connect to the brain. If this happens, hearing loss becomes permanent.
小題1:Which of the following shows that you are suffering hearing loss?
A．You are interested to listen to others’ talking.
B．You have to read others’ expressions to understand them.
C．You can only understand others over the phone.
D．You always think you hear the ringing of the phone.
小題2: Which of the following is TRUE when you listen to music?
A．Listen at least an hour every time.
B．Turn up the volume to the highest level.
C．keep the sound lower than 60% of its highest volume.
D．Choose classical, rock or heavy metal music.
小題3:What is the correct order of causing permanent hearing loss?
a. The eardrum is broken.
b. The auditory nerves cannot receive sounds.
c. Tiny hairs are damaged.
d. Ear buds are placed directly in the ear canal.
e. High-volume music is played over a long time.
A．d-a-c-b-eB．e-c-a-b-dC．b-c-a-d-eD．d-e-a-c-b
小題4:This passage is mainly about      .
A．music that teenagers likeB．hearing problems caused by the loud world
C．ways that teenagers enjoy music D．dangerous modern lifestyles of teenagers.

Elderly adults who regularly drink green tea may stay more agile (敏捷的) and independent than their peers over time, according to a Japanese study that covered thousands of people.
Green tea contains antioxidant chemicals (抗氧化物) that may help stop the cell damage that can lead to disease. Researchers have been studying green tea’s effect on everything from cholesterol (膽固醇) to the risk of certain cancers, with mixed results so far.
They found those who drank the most green tea were the least likely to develop “functional disability”, or problems with daily activities or basic needs, such as dressing or bathing.
Specifically, almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled, compared with just over 7 percent of people who drank at least five cups a day.
The study did not prove that green tea alone kept people agile as they grew older. Green-tea lovers generally had healthier diets, including more fish, vegetables and fruit, as well as more education, lower smoking rates, fewer heart attacks and strokes, and greater mental sharpness. They also tended to be more socially active and have more friends and family to rely on. But even with those factors accounted for, green tea itself was tied to a lower disability risk, the researchers said.
People who drank at least five cups a day were one-third less likely to develop disabilities than those who had less than a cup per day. Those people who averaged three or four cups a day had a 25 percent lower risk.
Although it’s not clear how green tea might offer a buffer (緩沖) against disability, Tomata’s team did note that one recent study found green tea extracts (提取物) seem to increase leg muscle strength in older women.
While green tea and its extracts are considered safe in small amounts, they do contain caffeine and small amounts of vitamin K, which means it could affect drugs that prevent blood clotting (凝固).
小題1:What can be learned from the passage?
A．Antioxidant chemicals can lead to disease.
B．Those who often drank green tea can’t develop “functional disability”.
C．“Functional disability” is related to problems with daily activities or basic needs.
D．People who drank at least five cups a day are not likely to become functionally disabled.
小題2:What does the fifth paragraph mainly tell us?
A．How the study was proved.B．Why green tea-lovers can keep agile.
C．What healthier diets include.D．How to lower disability risk.
小題3:What have the Researchers discovered?
A．Those who drank green tea can't develop “functional disability”.
B．Green tea alone kept people agile as they grew older.
C．How green tea might offer a buffer against disability.
D．Green tea extracts (提取物) seem to increase leg muscle strength in older women.

When we think about happiness, we usually think of something extraordinary, a pinnacle (頂點) of sheer (純粹的) delight. And those pinnacles seem to get rarer the older we get.
 1   I remember playing police and robbers in the woods, getting a speaking part in the school play. Of course, kids also experience lows, but their delight at such peaks of pleasure as winning a race or getting a new bike is unreserved.
For teenagers, or people under 20 the concept of happiness changes.   2   I can still feel the pain of not being invited to a party that almost everyone else was going to. I also remember the great happiness of being invited at another event to dance with a very handsome young man.
In adulthood the things that bring great joy—birth, love, marriage—also bring responsibility and the risk of loss.   3   For adults, happiness is complex.
 4   But I think a better definition of happiness is “ the ability to enjoy something”. The more we can enjoy what we have, the happier we are. It's easy to overlook the pleasure we get from loving and being loved, the company of friends, the freedom to live where we please, even good health.
While happiness may be more complex for us, the solution is the same as ever. Happiness isn't about what happens to us; it’s the ability to find a positive for every negative, and view a difficulty as a challenge.   5  
A．Love may not last; loved ones die.
B．For a child, happiness has a magic quality.
C．Happiness is the meaning and the purpose of life.
D．Being happy doesn’t mean that everything is perfect.
E. The dictionary defines “happy” as “l(fā)ucky” or “ fortunate”.
F. It's not wishing for what we don't have, but enjoying what we do possess.
G. Suddenly it’s conditional on such things as excitement, love, and popularity.
