The three groups of mice in the experiment were _ 24        __in age at young, middle-aged, and elderly humans.The mice were__25     _on a thread-mill (踏車) 30 minutes a day for a five-week period.At the end of that time, the young mice’s leg muscles had increased almost 30 percent in weight, but those of the old mice were reduced by 25 percent.No  26            pattern showed for the middle-aged mice.
David Gershon, an expert who carried out the experiment, explained that the older mice’ muscles were probably already_ 27      _down and that exercise worsened the _ 28       _.An earlier study by Gershon showed that middle-aged mice benefited from exercise if they started exercising young and continued it.
It’s clear that because the tests were done on mice, drawing conclusions about humans is too early.But the studies do not totally _ 29       _the theory that exercise is good under any conditions.Let’s use the tests on mice as a _ 30         _ for other studies.

If you do not use your arm or your legs for some time, they become weak; when you start using them again, they slowly become strong again. Everybody knows that. Yet many people do not seem to know that memory works in the same way. When someone says that he has a good memory, he really means that he keeps his memory in practice by using it. When someone else says that his memory is poor, he really means that he does not give it enough chance to become strong. If a friend says that his arms and legs are weak, we know that it is his own fault. But if he tells us that he has a poor memory, many of us think that his parents are to blame, and few of us know that it is just his own fault. Have you ever found that some people can’t read or write but usually they have better memories? This is because they cannot read or write and they have to remember things; they cannot write down in a little notebook. They have to remember days, names, songs and stories; so their memory is the whole time being exercised. So if you want to have a good memory, learn from the people: Practice remembering.
58. What is the main reason for one is poor memory? (回答詞數(shù)不超過(guò)8個(gè))
59. What will happen if you do not use your arms or legs for some time? (回答詞數(shù)不超過(guò)5個(gè))

Alzheimer's disease affects millions of people around the world. American researchers say the disease will affect more than one hundred million people worldwide by the year twenty fifty. That would be four times the current number. Researchers and doctors have been studying Alzheimer's patients for a century. Yet the cause and cure for the mental sickness are still unknown. However, some researchers have made important steps towards understanding it.
Several early signs of the disease involve memory and thought processes. At first, patients have trouble remembering little things. Later, they have trouble remembering more important things, such as the names of their children.
There are also some physical tests that might show who is at risk of developing Alzheimer's disease. The tests look for proteins in brain and spinal cord fluid. The proteins appear to be found only in people with the disease. The protein tests correctly identify the presence of the disease in about ninety percent of patients.
Now, a much simpler physical test to predict Alzheimer's risk has been developed. Researchers found that trouble with the sense of smell can be one of the first signs of Alzheimer's. Using this information, they developed a test in which people were asked to identify twelve familiar smells. These smells included cinnamon, black pepper, chocolate, paint thinner, and smoke.
The study continued for five years. During this period, the same people were asked to take several tests measuring their memory and thought abilities. Fifty percent of those who could not identify at least four of the smells in the first test had trouble with their memory and thinking in the next five years.
Another study has shown a possible way to reduce a person's chances of developing Alzheimer's disease in old age. Researchers in Chicago found that people who use their brains more often are less likely to develop Alzheimer's disease. Those who read a newspaper, or play chess or word games are about three times less likely to develop the condition.
Researchers say they still do not know what causes Alzheimer's disease. But they say these findings might help prevent the disease in the future.
41. What’s the main idea of the passage?
A. Some early signs of the Alzheimer's disease.
B. Some physical tests about Alzheimer's disease.
C. The research about Alzheimer's disease.
D. The patients of Alzheimer's disease.
42. What’s the current number of Alzheimer’s patients?
A. 100 million               B. 25 million         C. 400 million              D. 2050 million
43. What is not the early signs of the Alzheimer's disease according to the passage?
A. Poor memory                           B. Proteins exist in the brain.
C. Trouble with the sense of smell.             D. Less use of the brain.
44. What does the underlined word “it” in paragraph 1 refer to?
A. Alzheimer's disease.                               B. Alzheimer's patients. 
C. The cause and cure.                                    D. The research.

Faces show emotions. Psychology; computer science, and engineering researchers are joining forces to teach machines to read expressions. If they succeed, your computer may one day "read" your mood and cooperate. Machines equipped with emotional skills could also be used in teaching , robotics, gaming, security, and for psychological diagnoses(診斷).
"Mind Reader", a system developed by Rosalind Picard at the Massachusetts Institute of Technology in the US, uses input from a video camera to do real-time analysis of facial expressions. It reports on whether you seem "interested" or “agreeable” or if you're "confused".
The system can help people detect others' emotions. Picard says this means we could teach a machine to be as sensitive as a human. In fact, a machine can be even smarter: than people since it can tell if a person is lying or just "performing" by analyzing one's facial movements. Jeffrey Cohn, a psychologist at the University of Pittsburgh, uses the Facial Action Coding System to detect human emotions. "The face is always visible," Cohn says, "People communicate a lot about feelings and thoughts through facial expression."
Cohn studied a videotape of criminal who professed to be sad about the murder of several family members and tried to pin the blame on some one else. But Cohn saw no real sadness in the woman's face. Sadness is a combination of facial action units that are difficult to do voluntarily. This means, even though your mouth lies, your face doesn't, and the machine will know it all.
1.People can know a person's emotions from his _____.
A.body movement             B.facial expressions
C.psychological reactions   D.mood and attitude
2.Recent technology development makes ______ by machines possible.
A.mind reading          B.body reading
C.face reading           D.mood reading
3.According to the passage,______.
A.people can no longer tell lies before the new machine
B.people still can tell lies in front of the new machine
C.people have different emotions before the new machine
D.sadness is often difficult to be seen
4.The underlined word "professed" most probably means_______.
A.to pretend something as true B.to acknowledge
C.to show           D.to prove
5.From the passage we can infer that ________.
A.the technology still needs improvement.
B.people can do everything with the new machine .
C.face reading technology is nothing new.
D.face reading technology will be widely used in the future.

A super drug that could remove Alzheimer’s (老年癡呆癥),heart disease and diabetes (糖尿病) and help people live to 100 is being developed by scientists. Their research is based on the identification of three genes that help prolong lives and prevent diseases which occur in old age. Medically controlling the proteins made by the “ longevity genes” will allow millions to live longer, predicts Dr Nir Barzilai.
Those whose DNA strongly features the three genes are 80 percent less likely to develop Alzheimer’s. The genes also fight against the deadly impact of smoking, poor diet, obesity and lack of exercise.
Already, several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage old age. “ The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing,” he said.
Of the three longevity genes, two genes increase the production of so-called good cholesterol(膽固醇), which reduces the risk of heart disease. The third prevents diabetes. They were discovered by Dr Barzilai’s team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the group, which shared relatively few common ancestors, was 20 times more likely to hit the entury. Dr Barzilai said: “ 30 percent of them were obese or overweight and 30 percent smoked two acks of cigarettes a day for more than 40 years, however they can live to 100.”
But Andrew Ketteringham of the Alzheimer’s Society said: “Alzheimer’s disease, a most common disease, is likely to be caused by a combination of genetic disosition(遺傳傾向), lifestyles and life events. Many genes are probably involved.
小題1:Some people are able to live to 100 years because of ______.
A.a(chǎn) magical medicineB.three special genesC.good living habitsD.longevity proteins
小題2:Why does the discovery of the longevity genes mean a lot?
A.Because it can bring great benefits to scientific labs.
B.Because it can help people change their unhealthy genes
C.Because it helps produce a drug that can make people live longer.
D.Because it will help scientists build up a new branch of biology.
小題3: From Paragraph 4 we can infer that ________.
A.longevity genes can create good cholesterol.
B.the volunteers share some common ancestors
C.bad habits are likely to have no effect on the volunteers
D.longevity genes protect the volunteers against bad habits
小題4:What is Andrew Ketteringham’s attitude toward the study?
A.PositiveB.NegativeC.CriticalD.Cautious

Cancer is among the top killer diseases in our society today and scientists have found out that stress(緊張) helps to bring it on. It is worthwhile to consider, therefore, what are the causes of stress in our life, and whether we can do anything about them.
Are we underemployed, or overburdened with too many responsibilities? Do we have a right balance of work and leisure(閑暇) in our lives? Are our relationships with family, friends or fellow workers all they should be?
All these things can be a cause of stress, and it is best to face them honestly, and bring our frustrations(沮喪,挫敗) into the open. People who have a good row and then forget it are doing their health better than shoes who bottle up their feelings.
If our self-examination has brought any causes of stress to light, let us consider what we can do about them. It is possible to change jobs. We can make more leisure and fill it more happily, if we will accept a different living standard. We can improve our personal relationships by a different attitude. It is we who allow other people to make ourselves unhappy. Often the little things that disturb us are not worth an hour’s anger. The teaching in the Bible “Don’t let the sun go down upon your wrath(憤怒)” is good advice from the health point of view as well as the religions(宗教,信仰).

Anxiety is the proper emotion when the immediate personal terror — of a volcano, an arrow, a stab(刺傷)in the back and other disasters — is directed against one’s self–disappears.
The kind of world that produces anxiety is actually a world of relative safety, a world in which no one feels that he himself is facing sudden death. The anxiety exists as an uneasy state of mind, in which one has a feeling that something unspecified(不具體的)and indeterminable may go wrong. If the world seems to be going well, this produces anxiety — for good times may end. If the world is going badly — it may get worse. Anxiety tends to be without focus;the anxious person doesn’t know whether to blame himself or other people. He isn’t sure whether it is a change in climate or the atom bomb that is to blame for this unclear sense of unease.
It is clear that we have developed a society which depends on having the right amount of anxiety to make it work. While we agree that too much anxiety is harmful to mental health, we have come to rely on anxiety to push us into seeing a doctor about a symptom(癥狀)which may indicate cancer, into checking up on that old life–insurance policy which may have out–of–date provisions in it, into having a conference with Bill’s teacher even though his report card looks all right.
People who are anxious enough keep their car insurance up, have the brakes checked, and don’t take a second drink when they have to drive. People who are too anxious either refuse to go into cars at all or drive so tensely that they help cause accidents. People who aren’t anxious enough take chance after chance, which increases the terrible accidents of the roads.
1. In the world that produces anxiety, _____.
A. people have sudden uneasiness        B. everything goes well
C. people are clear about their life        D. danger is almost everywhere
2. The author holds that _____.
A. anxiety is a good thing
B. anxiety is a symptom of mental illness
C. some anxiety can lead to changes for the better
D. no anxiety is bad for society
3. Accidents of the road tend to be caused by _____.
A. all those who are too anxious           B. all those who have anxiety
C. those who have no anxiety             D. those who are not anxious enough
4. The best title for the passage would be _____.
A. Anxiety                            B. The Right Amount of Anxiety
C. Anxiety vs Safety                    D. Different Attitudes to Anxiety

Everyone knows what a needle is. Of course there are needles and needles: Needles for sewing machines, needles for injection(注射), you name it. But few people think of the wonder : a needle works in the hands of those who practice acupuncture(針刺療法).
During the past ten years or so, I have been suffering from terrible headache. It seems to be getting from bad to worse these days . Last night I got a sudden pain in my head.

These needles may possibly do you some good.” I agreed. In a moment, he had taken out a few needles from his purse. Without a moment’s delay, he fixed a few needles into the skin on my head here and there, Before long, I felt thoroughly relieved(緩解疼痛).
