Imagine your body is like the house you live in．Every day, your family creates rubbish．The rubbish builds up until it is put out for the weekly garbage collection．
Now, say you put three bags of garbage out．but because one of the collectors was away sick, only two bags are collected．You take the leftover bag inside to be put out again next week．The following week you put on another three bags．plus the leftover bag from last week．But again, only two bags are collected．Imagine this cycle is repeated over the following weeks．
This is a simple description of what happens to your body when your kidneys （腎臟）don't work efficiently．Your body is nol thoroughly emptied of waste products．Other areas of the bodv such as blood pressure and red blood cell production are affected and the insidious process that may lead to kidney failure begins．
It's not uncommon for people to lose up to 90% of their kidney function before deveoping any symptoms．There may be no warning signs. This makes early detection （診查）difficult．
Kidney's main job is to remote toxins（毒素） and unwanted water from our blood．Every day our kidneys clean an average of 200 litres of blood．Kidney failure may be a gradual and silent process, going unnoticed because there is no apparent pain．
Research shows that more than 35% of the patients requiring dialysis （透析）do not see a kidney specialist before they have to do so．Some risk factors for kidney disease such as age and genetic make up are out of our control; however, some changes in lifestyle may help prevent kidney damage．Two major risk factors for kidney disease, diabetes （糖尿�。゛nd high blood pressure, have been on the rise over the last few decades．Both conditions are chiefly affected by being overweight and not getting enough exercises, which are the potential risk factors for the kidney disease．
66．The author gives the example of the house we live in to indicate that ______．
A．it doesn't matter much if the waste in our body is not emptied in time
B．our body will not produce any waste if our kidneys work efficiently
C．it's important for our body to empty the waste in time every day
D．it's safe and harmless for our body to keep some waste
67．The underlined word “insidious” in Paragrap 3 means          .
A．smooth and safe                 B．a(chǎn)pparent and fast
C．gradual and unnoticed       D．long and painful
68．We can infer that when we find some symptoms related to our kidneys,          .
A．the kidney failure begins
B．the kidneys can still work properly
C．we have lost about 10% of kidney function
D．the kidneys may have been seriously damaged
69．How many risk factors of kidney disease are mentioned in the passage?
A．Six.     B．Five.  C．Four.  D．Two.
70．Which of the following helps prevent kidney damage most effectively?
A．Go to see a kidney specialist shortly before dialysis starts.

No matter how long your life, you will, at best, be able to read only a few books of all that have been written, and the few you do read should include the best. You can rejoice in the fact that the number of such is relatively small.
________________ Yet there is a surprising uniformity in the lists which represent the best choices of any period. In every age, the list makers include both ancient and modern books in their selections, and they always wonder whether the moderns are up to the great books of the past.
What are the signs by which we may recognize a great book? The four I will mention may not be all they are, but they are the ones I’ve found most useful in explaining my choices over the years.
Great books are probably the most widely read. They are not best sellers for a year or two. They are enduring best sellers. GONE WITH THE WIND has had relatively few readers compared to the plays of Shakespeare or DON QUIXOTE. It would be reasonable to estimate that Homer’s Iliad（伊麗亞特）has been read by at least 25,000,000 people in the last 3000 years.
Great books are popular, not pedantic. They are not written by specialists about specialties for specialists. Whether they are philosophy or science, or history or poetry, they treat of human, not academic problems. They are written for men, not professors. To read a textbook for advanced students, you have to read an elementary textbook first. But the great books can be considered elementary in the sense that they treat the elements of any subject matter. They are not related to one another as a series of textbooks, graded in difficulty or in the technicality of the problems with which they deal.
Great books are always contemporary, the most readable and instructive.
Great books deal with the persistently unsolved problems of human life. There are genuine mysteries in the world that mark the limits of human knowing and thinking. Inquiry not only begins with wonder, but usually ends with it also. Great minds acknowledge mysteries honestly. Wisdom is fortified, not destroyed, by understanding its limitations.
64．Which of the following can be put in the blank in the second paragraph?
A．Great books deal with the persistently unsolved problems of human life.
B．It is to be expected that the selections will change with the times
C．The listing of the best books is as old as reading and writing.
D．The fundamental human problems remain the same in all ages.
65．According to the author, Gone With The Wind is ________.
A．a(chǎn) best seller                                               
B．disgusted by readers who like Shakespeare
C．read more often than Don Quixote        
D．a(chǎn) great book
66．In the passage “pedantic” means ________.
A．showing the feelings, esp, those of kindness, which people are supposed to have
B．serving as practical examples
C．being elementary
D．paying too much attention to details in books
67．The best title for this passage is ________.
A．Great Books in Your Life       B．Great Books in Your Speciality
C．How to Find a Great Book?    D．What Is a Great Book?

People who have lost the ability to understand or use words due to brain damage are called aphasics(失語癥患者).Such patients can be extremely good at something else.From the changing expressions on speakers’ faces and the tones of their voices,they can tell lies from truths.
Doctors studying the human brain have given a number of examples of this amazing power of aphasics.Some have even compared this power to that of a dog with an ability to find out the drugs hidden in the baggage.
Recently,scientists carried out tests to see if all that was said about aphasics was true.THEY STUDIED A MIXED GROUP OF PEOPLE.Some were normal;others were aphasics.It was proved that the aphasics were far ahead of the normal people in recognizing false speeches—in most cases,the normal people were fooled by words,but the aphasics were not.
Some years ago,Dr.Oliver Sacks wrote in his book about his experiences with aphasics.He mentioned a particular case in a hospital.Some aphasics were watching the president giving a speech on TV.Since the president had been an actor earlier,making a good speech was no problem for him.He was trying to put his feelings into every word of his speech.
But his way of speaking had the opposite effect on the patients.They didn’t seem to believe him.Instead,they burst into laughter.The aphasics knew that the president did not mean a word of what he was saying.He was lying!
Many doctors see aphasics as people who are not completely normal because they lack the ability to understand words.However,according to Dr.Sacks,they are more gifted than normal people.Normal people may get carried away by words.Aphasics seem to understand human expressions better,though they cannot understand words.
小題1:What is so surprising about aphasics?
A．They can fool other people.B．They can find out the hidden drugs.
C．They can understand language better.D．They can tell whether people are lying.
小題2:How did the scientists study aphasics?
A．By asking them to watch TV together.
B．By organizing them into acting groups.
C．By comparing them with normal people.
D．By giving them chances to speak on TV.
小題3:What do we learn from this text?
A．What one says reflects how one feels.
B．Aphasics have richer feelings than others.
C．Normal people often tell lies in their speeches.
D．People poor at one thing can be good at another.

The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana（大麻）. That is the claim of psychologists who have found that tapping away on a mobile phone or computer keypad or checking them for electronic messages temporarily knocks up to ten points off the user’s IQ.
This rate of decline in intelligence compares unfavorably with the four-point drop in IQ associated with smoking marijuana, according to British researchers, who have labeled（把……稱為）the fleeting phenomenon of enhanced stupidity as “infomania”.
The noticeable drop in IQ is believed to be the result of the constant distraction of “always on” technology when employees should be concentrating on what they are paid to do. Infomania means that they lose concentration as their minds remain fixed in an almost permanent state of readiness to react to technology instead of focusing on the tasks in hand.
The brain also finds it hard to deal with keeping lots of tasks in motion at once, reducing its overall effectiveness. While modern technology can have huge benefits, excessive(過度的)use can be damaging not only to a person’s mind, but to his or her social life.
Eighty volunteers took part in clinical trials on IQ damage and 1,100 adults were interviewed.
More than six in ten people polled admitted that they were addicted to checking their e-mail and text messages so that they examined work-related ones even when at home or on holiday. Half said that they always responded immediately to an e-mail and one in five would interrupt a meeting to do so.
Furthermore, infomania is having a negative effect on work colleagues, increasing stress and disagreeing feelings. Nine out of ten polled thought that colleagues who answered e-mails or messages during a face-to-face meeting were extremely rude. Yet one in three Britons believed that it was not only acceptable, but actually diligent and efficient to do so.
67. What does the underlined part mean?
A.A person’s IQ drops ten points if he or she always checks electronic messages.
B. The person who has a higher IQ enjoys checking electronic messages.
C. The person who has a lower IQ enjoys checking electronic messages.
D. A person’s IQ is ten points higher if he or she always checks electronic messages.
68. What happens to people with infomania?
A. People with infomania can only concentrate on their tasks in hand.
B. people with infomania are addicted to smoking marijuana.
C. People with infomania can’t respond to technology immediately.
D. People with infomania can’t concentrate on their tasks in hand.
69. From the passage, we can learn that ______.
A. about 550 interviewees responded to an e-mail immediately
B. about 670 interviewees responded to an e-mail immediately
C. about 50 taking part in clinical trials on IQ were addicted to checking e-mails
D. about 16 taking part in clinical trials on IQ refused to answer e-mails immediately
70. What is the main idea of this passage?
A. The regular use of text messages and e-mails can be compared to smoking marijuana.
B. Modern technology can damage a person’s mind.
C. The regular use of text messages and e-mails can harm your IQ.
D. Electronic messages have side effects on the user’s life.

Sleeping in on Saturday after a few weeks of too little shuteye may feel refreshing, but it can give a false sense of security.
New research shows long-term sleep loss cannot be cured that easily. Scientists researched the effects of short- and long-term sleep loss and found that those who suffer long-term sleep loss may function normally soon after waking up, but experience steadily slower reaction times as the day goes by, even if they had tried to catch up the previous night.
The research has important safety significances in an increasingly busy society, not just for shift-workers but for the roughly one in six Americans who regularly get six hours or less of sleep a night.
“We know that staying awake 24 hours without sleep will affect your performance to do all sorts of things, and this effect equals to drinking too much when driving,” said lead researcher Dr. Daniel Cohen of Boston’s Brigham and Women’s Hospital. But when those who suffer long-term sleep loss become all-nighters, “the harm is increased ten times,” Cohen said.
The National Institutes of Health says adults need seven hours to nine hours of sleep for good health. Regularly getting too little sleep increases the risk of health problems, including memory impairment and a weakened immune system. More immediately, too little sleep affects reaction times; sleepiness is to blame for car crashes and other accidents.
It has critically important complicated and unexpected results for anyone who works “crazy hours” and thinks they are performing fine with a few hours of weeknight sleep, said Harris, director at New York’s Montefiore Medical Center. “Don’t think you can just bank up your sleep on the weekend, because it doesn’t work that way,” he warned.
小題1:The text mainly advises people ______.
A．to sleep more timeB．to sleep in on Saturday
C．to sleep scientifically D．to sleep little on weekend
小題2:People with long-term sleep loss ______.
A．a(chǎn)re quicker in thinkingB．may feel refreshed soon after waking up
C．a(chǎn)re surely energeticD．can have a strong sense of security
小題3:What can we learn from the text?
A．Most of the Americans get six hours or less of sleep a night.
B．Staying up is worse for those who suffer long-term sleep loss.
C．Traffic accidents have little to do with sleepiness.
D．One in six Americans are all-nighters.
小題4:Which of the following is the immediate effect of long-term sleep loss?
A．Health problemsB．Immune system
C．Reaction timesD．Memory impairment
小題5:The underlined phrase “bank up” in the last paragraph most probably means ____.
A．pile upB．pick upC．a(chǎn)dd upD．build up

D        
"In only six days I lost seven pounds of weight. "
"Two full inches in the first three days!"
These are the kinds of statements used in magazine, newspaper, radio and television ads, promising new shapes and new looks to those who buy the medicine or the device. The promoters of products say they can shape the legs, slim the face, smooth wrinkles, or in some other way to add to beauty or desirability.
Often such products are nothing more than money-making things for their promoters. The results they produce are questionable and some are dangerous to health.
To understand how these products can be legally promoted to the public, it is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA(Food and Drug Administration )can require proof (證明) under the Food, Drug, and Cosmetic Act that is safe and effective before it is put on the market. But if the product is a device, FDA has no authority to require premarketing proof of safety or effectiveness. If a product already on the market is a danger to health. FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action, including seizure (查封) of the product.
One notable case a few years ago involved an electrical device called the Relaxacisor, which had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds that it was dangerous to health and life.
Obviously, most of the devices on the market have never been the subject of court proceedings (法律訴訟),and new devices appear continually. Before buying, it is up to the consumer to judge the safety or effectiveness of such items.
71. It can be inferred that the ads mentioned in the text are        .
A. objective    B. costly    C. unreliable    D. illegal
72. Which of the following is true according to the text?
A. The court is in charge of removing dangerous products.
B. New products are more likely to be questionable.
C. The production of a device must be approved by FDA.
D. The promoters usually just care about profits.
73. FDA can ask for the proof of safety and effectiveness of a product        .
A. if it is a drug      
B. if it is a device
C. if its consumers make complaints
D. if its distributors challenge FDA's authority
74. The Relaxacisor is mentioned as        .
A. a product which was designed to produce electricity
B. a product whose distributor was involved in a legal case
C. a successful advertisement of a beauty product
D. an example of a quality beauty product
75. The author intends to        .
A. make consumers aware of the promoters' false promises
B. show the weakness of the law on product safety
C. give advice on how to keep young and beautiful
D. introduce the organization of FDA
