题目内容

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(诊断).
"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.

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

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.

Sub-health, also called the third state or gray state, is explained as a borderline state between health and disease．
According to the investigation by the National Health Organization, over 45 percent of sub-healthy people are middle-aged or elderly．The percentage is even higher among people who work in management positions as well as students around exam-week．
Symptoms(征兆)include a lack of energy, depression(压抑),slow reactions, insomnia(失眠),agitation, and poor memory．Other symptoms include shortness of breath, sweating and aching in the waist and legs．
The key to preventing and recovering from sub-health, according to some medical experts, is to form good living habits, alternate work and rest, exercise regularly, and take part in open air activities．
As for meals, people are advised to eat less salt and sugar．They should also eat more fresh vegetables, fruits, fish because they are rich in nutritional elements…vitamins and trace elements …vitamins and trace elements…that are important to the body．

Recently some American scientists have given a useful sincere piece of advice to people in industrialized nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago.
The scientists say that the human body has changed very little since humans first appeared on the earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times, so they are called “diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes ( 中风 ) are examples of such diseases.
Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and that of today.
Stone-age people hunted wild animals for their meat, which had much less fat than domestic or tame ones ( 家畜 ). They also ate a lot of fresh wild vegetables and fruits. They didn’t have milk or any other dairy products, and they made very little use of grains. But today, we eat a large amount of these. We eat six times more salt than our remote ancestors. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C.
People today probably do not want to live the way people thousands of years ago did, but scientists say that we would be much healthier if we ate much the same way as remote ancestors did, cutting the amount of fatty, salty and sweet food.
67. What is the main cause that people suffer from a lot of new sicknesses?
A. Ancient people did a great deal of physical exercise.
B. People today have a lot of alcohol.
C. People today have more tobacco.
D. Food today is quite different from that of ancient times.
68. Which of the following belongs to the dairy products?
A. Milk             B. Corn     C. Pork            D. Flour
69. New kinds of sicknesses have been found because ________.
A. the human body has changed compared with humans who first appeared on the earth
B. the way we live has changed a little
C. our body can’t deal with the changes in life style
D. the way we live today is proper for the human body
70. According to some scientists, Stone-age people were much healthier than people today because they ate a lot of ________.
A. milk and other dairy products                        B. salt and sugar
C. wild animals, fresh wild vegetables and fruits     D. grain foods

I have a close friend who has a good family tradition, that is, each year after Thanksgiving dinner, all of the people sit around in the living room and each person takes a few minutes and gives thanks for what really matters and what has added value to their life over the last year. This is something I valued and followed. I have thought about a lot in the last year, and I finally came up with two things.
The first one is the healthiness of my daughter. She’s as healthy as she can be, and her weight and height are in good condition and she has no illnesses or genetic diseases. I am so thankful for having this wonderful baby in my life, and thankful that she has the gift of good health.
Secondly, I am thankful for the discovery of the value of writing in my life. A year ago, my website. The simple Dollar was only a few weeks old and was far from popular, but on Thanksgiving Day Last year it had about three score readers who ordered it in advance. The process of writing was bringing me enjoyment, but I hadn’t yet realized that I could be successful in it and attract many readers. This past year showed me a lot and I am deeply thankful for it.
After thinking for a while, I began to realize that it was a very powerful and wonderful positive exercise. You spend time reflecting deeply on the positive things in your life, and you often realize that even when things are bad, you do have a lot to be thankful for because there is lots of good in your life, and it can shine a bright light even in a dark spot in your life.
72．What is the good family tradition of the author’s friend’s?

A．hold a positive attitude    B．reflect on their mistakes
C．have low expectations of life   D．neglect their disadvantages

The concept of personal choice in relation to health behaviors is an important one. An estimated 90 percent of all illnesses may be preventable if individuals would make sound personal health choice and do not like to see it restricted when it is within the legal and moral boundaries of society. The structure of American society allows us to make almost all our own personal decisions that may concern our health. If we so desire, we can smoke, drink excessively, refuse to wear seat belts, eat whatever foods we want, and live a completely sedentary life style without any exercise. The freedom to make such personal decisions is a fundamental aspect of our society, although the wisdom of these decisions can be questioned. Personal choices relative to health often cause a difficulty. As one example, a teenager may know the facts relative to smoking cigarettes and health but may be pressured by friends into believing it is the socially accepted thing to do.?
A multitude of factors, both inherited and environmental, influence the development of health related behaviors, and it is beyond the scope of this text to discuss all these factors as they may affect any given individual. However, the decision to adopt a particular health related behavior is usually one of personal choices. There are healthy choices and there are unhealthy choices. In discussing the morals of personal choice, Fries and Grapo drew a comparison. They suggest that to knowingly give oneself over to a behavior that has a statistical probability of shortening life is similar to attempting suicide. Thus, for those individuals who are interested in preserving both the quality and quantity of life, personal health choices should reflect those behaviors that are associated with a statistical probability of increased vitality and longevity.
68．The concept of personal choice concerning health is important because ____.
A．personal health choice helps cure most illness
B．it helps raise the level of our medical knowledge
C．it is essential to personal freedom in American society
D．wrong decisions could lead to poor health
69．To “live a completely sedentary life style”(L7,Para.1)in the passage means____.
A．to “live an inactive life” B．to “live a decent life”
C．to “live a life with complete freedom” D．to “live a life of vice”
70．Sound personal health choice is often difficult to make because ____. ?
A．current medical knowledge is still insufficient
B．there are many factors influencing our decisions
C．few people are willing to trade the quality of life for the quantity of life
D．people are usually influenced by the behavior of their friends

It was late Wednesday night when the dreadful phone call reached our home . I rememeber laying in my bed trying to fall asleep when I heard the phone ring . Interested in who would be calling so late I sat up, so I could hear the phone call better . To my surprise , I heard my mom burst into tears , “ Get the car , dear ! Andrea has been in a car accident .”
We ran every red light on the way to the hospital and our tires screeched(发出刺耳声) around every corner . We got to the hospital , but were not allowed to see Andrea . The next morning , after wearing masks , we were allowed to go to the ICU to see Andrea . Well , the least I could say was that everything was injured in her body and she lost all of her memories . It was a fatal car accident .
Over the next two months , I lived more at the hospital than I did at my house . I watched as Andrea worked so hard to gain back everyday motor skills . She never once complained or pitied herself , and her determined spirit was shining through . After two weeks in the ICU and two months of regular hospital treatment , Andrea came home . She missed several months of school , so it was hard for her to catch up . Andrea had many tasks to accomplish , and no matter how hard it was , she stuck to it until the job was done . Though she was busy dealing with the pain and the therapy , she always found time to love and play with me .
I’ll never forget the impact that this incident made on my life . I admire my sister for her strong-willed personality and her determined spirit . Today she is perfectly normal , despite the scars and the pins holding her leg in place . I couldn’t ask for a better sister or a hero in my life .

We all accept that sports should stress skill over luck，and fairness over privilege(特权)．
They should be accessible to many and fun to watch．In the end，a sport,s champion should re-
present shared values and served as a role model．
But with today,s advances in technology，the power of sports equipment makers offers great
opportunity for the athletes who have access to the latest technology.
In 2008,108 world records were broken in the sport of swimming．The average number of
world records set in swimming in all past Olympic years is about 22．The average number of
world records set in a non-Olympic year is about 5．Now there are no“old”world records．
Suit technology has been the most widely recognized difference．The sharkskin suit and the
“paper”suits were all made public by suit manufactures before the Olympic．
As records continue to be broken，the Internet message boards for the swimming community
have taken a darker view of suit technology．“Time is meaningless”is one quote．I tend to agree．Some of the times I see being posted today are simply legends(传奇)．
Am I against suit technology?Not really．But 2008 marked an unbelievable change in the
sport of swimming．People are saying，“Bigger，faster，stronger at any cost!”，wanting no limits on technology，either suits or drugs．I am not one of those people．
I am a guy that recognized the sport of swimming being as simple as man vs．water．It used
to be the swimmer in the suit，not the suit on the swimmer．How times have changed．
53．According to the first paragraph，it is a common belief that________.
A．only a few people have chances to take part in sports
B．the latest suit technology should not be used in sports
C．sports should be interesting for people to watch
D．luck plays an important role in Olympic Games
54．It can be learned from the passage that_______.
A．the author is against the latest technology in sports
B．the athletes have become more skilled than before
C．some records are hard to break without technology
D．advanced suits and drugs can be used in Olympics
55．What does“Time is meaningless”mean in the swimming community?
A．Breaking records in swimming is too easy for most athelets．
B．It,s technology rather than skill that counts in some records．
C．Many athletes break records by luck and taking drugs．
D．Some rules aren,t obeyed when Olympic records are broken．
56．What,s the author,s opinion of the present sports?
A．Latest technology should be encouraged in compitition among athelets．
B．Time should be measured in a different way in modern Olympic Games．
C．All of the athletes should wear the same suits to ensure fairness．
D. Competition in skill should come first instead of that in equipment。
