Contrary to popular belief, our framework of bones isnt a rigid and unchanging structure.

Each year, our bodies replace about 20 percent of our bones tissue, which means that our activities at every age influence their health. Sections of old bone break down, creating gaps to be filled by new bone. Until about age 30, we build bone very efficiently, so making the right health moves, such as exercising and getting enough calcium, helps your bony framework reach its genetically determined peak strength. Think of your bones as a retirement fund: The more you deposit when you re young, the better off you will be in later years, when you need to draw on your reserves. The problem is that kids prefer soda to a glass of milk: they are coming up short of the calcium and vitamin D they need to build up good health. Many of them also lead an inactive life, so they arent getting the bone-building benefits of regular exercise either. That s a problem every parent should be concerned about.

In the year 2100, the world is going to have a population of about 8 billion. Most scienti

sts agree that the most severe problem is food supply. Who is going to feed all these people？ Where is the food going to come from？ Are we going to have enough food？ Are we going to produce more artificial foods？ One way of improving the situation is for people to eat less meat. Why？ Because it takes 4 kilos of grain protein(蛋白质)to produce half a kilo of meat protein. Clearly, there is not going to be sufficient meat protein for 8 billion people. Therefore, it will also be necessary to change eating habits because meat is the main part of many people s food today. A possible solution to this latter problem is the soybean(大豆). The soybean plant produces beans which have a very high fat and protein content. Scientists can now make these look and taste like real meat. They can also make many other artificial products such as soybean milk, for example, which has a taste of milk and can be used in cooking in very much the same ways as cow s milk. In fact, one woman in the United States fed her family only on soybeans for a year! She gave them soybean beef, soybean chicken, soybean milk, and sometimes just soybeans. Possibly, we are all going to eat soybeans in the future and finally give up meat completely from our tables.

What is the main subject of the passage？

A．A solution to man"s food problem.

B．A solution to the population problem.

C．Advantages of soybean.

D．How to develop good eating habits.

1. “The Nobel Prize in Physiology or Medicine 2004”Press Release(15分)

4 October 2004

The Nobel Assemblyat Karolinska Institutet has today decided to award The Nobel Prize in Physiology or Medicine for 2004 jointly toRichard Axel and Linda B. Buckfor their discoveries of "odorant receptors and the organization of the olfactory system"

Summary

The sense of smell long remained the most enigmatic of our senses. The basic principles for recognizing and remembering about 10,000 different odours were not understood. This year's Nobel Laureates in Physiology or Medicine have solved this problem and in a series of pioneering studies clarified how our olfactory system works. They discovered a large gene family, comprised of some 1,000 different genes (three per cent of our genes) that give rise to an equivalent number of olfactory receptor types. These receptors are located on the olfactory receptor cells, which occupy a small area in the upper part of the nasal epithelium and detect the inhaled odorant molecules.

Each olfactory receptor cell possesses only one type of odorant receptor, and each receptor can detect a limited number of odorant substances. Our olfactory receptor cells are therefore highly specialized for a few odours. The cells send thin nerve processes directly to distinct micro domains, glomeruli, in the olfactory bulb, the primary olfactory area of the brain. Receptor cells carrying the same type of receptor send their nerve processes to the same glomerulus. From these micro domains in the olfactory bulb the information is relayed further to other parts of the brain, where the information from several olfactory receptors is combined, forming a pattern. Therefore, we can consciously experience the smell of a lilac flower in the spring and recall this olfactory memory at other times.

Richard Axel, New York, USA, and Linda Buck, Seattle, USA, published the fundamental paper jointly in 1991, in which they described the very large family of about one thousand genes for odorant receptors. Axel and Buck have since worked independent of each other, and they have in several elegant, often parallel, studies clarified the olfactory system, from the molecular level to the organization of the cells.

It is difficult to imagine what life would be like without memory. （79)The meanings of tho

It is difficult to imagine what life would be like without memory. (79)The meanings of thousands of everyday perceptions, the bases for the decisions we make, and the roots of our habits and skills are to be found in our past experiences, which are brought into the present by memory. Memory can be defined as the capacity to keep information available for later use. It includes not only "remembering" things like arithmetic or historical facts, but also involving any change in the way an animal typically behaves. (80)Memory is involved when a rat gives up eating grain because he has sniffed something suspicious in the grain pile.Memory is also involved when a six-year-old child learns to swing a baseball bat. Memory exists not only in humans and animals but also in some physical objects and machines. Computers, for example, contain devices for storing data for later use. It is interesting to compare the memory-storage capacity of a computer with that of a human being. The instant-access memory of a large computer may hold up to 100,000 "words"—ready for instant use. An average U. S. teenager probably recognizes the meaning of about 100,000 words of English. However, this is but a fraction of the total amount of information which the teenager has stored. Consider, for example, the number of faces and places that the teenager can recognize on sight. The use of words is the basis of the advanced problem-solving intelligence of human beings. A large part of a persons memory is in terms of words and combinations of words.

According to the passage, memory is considered to be______.

A．the basis for decision making and problem solving

B．an ability to store experiences for future use

C．an intelligence typically possessed by human beings

D．the data mainly consisting of words and combinations of words

Running late again, I rushed into the Cub Scouts parents meeting, noting the surplus of em

pty chairs. At least, I wasn t the only one running behind, I told myself with great relief. The Cubmaster checked his watch, and with a barely audible sigh, started the meeting. As the Cubmaster explained the challenges that the group faced in the coming year, he pointed out that the empty chairs, which should have been filled with parent volunteers, were our biggest obstacles. As he spoke, I felt a rising sense of guilt mounting within me. Wasnt I looking forward to leaving my seven-year-old in the care of a competent adult while I ran errands？ I quickly came to realize that the problem wasn t just about empty chairs: it was also about people like me who were unwilling to sacrifice some of their time to a worthy cause. Before I could change my mind, I raised my hand to volunteer as den (幼年童子军小队)leader. Although I knew next to nothing about teaching a group of noisy and restless second-graders, I was determined to make it work. My first den meeting was as chaotic and noisy as the first day of a county fair. The boys were too excited to sit still. What have I gotten myself into？ I wondered, composing a letter of resignation in my head. Much to my surprise, the boys actually enjoyed themselves. They even invited their friends to join our den, and before long, our ranks swelled from four boys to ten. My son was thrilled to have his mom as den leader: it gave him bragging rights on the playground. As I walked through the school s parking lot, it was rare when one of "my" boys didn t call out a greeting or stop me for a quick hug and a story to share. They would talk with me about the little things going on in their lives—whether it was a loose tooth ready to wiggle its way out or a special event coming up. As I watched them, I thought of the empty chairs at that meeting and those who would never know this joy. After all, I gave those boys only one hour of my time every week, but they rewarded me with their hearts.

It is clear that the Cubmaster______.

A．felt sorry for what had happened

B．could hardly control his anger

C．was thankful to whoever had come

D．was disappointed with the situation

I saw an ad for a device that allows your dog to talk to you. Bow Lingual, a Japanese inve

ntion, entered the American market a couple of weeks ago. Named " The Dog Translator," it sold more than 250,000 units before heading here. And dont forget that it was sold at the price of $ 120 each. Its quite simple, really. A radio microphone attaches to your dog s collar, and a handheld receiver "translates" barks into 200 different phrases. The device determines your dogs emotion at the moment: happy, sad, frustrated, on-guard, assertive and needy. (In case you have a dog that barks only in Japanese or Korean, it comes with those translations, too.) As interesting as this new device is—again, I m kicking myself here—any dog owner worth his Milk-Bones knows this might not be all that necessary a purchase. Our dog, Murphy, for instance, has never had any problem whatsoever communicating with us. Not once in 13 years. Odd as it seems, we can figure out quite quickly what s on her mind. Just the cock of her head will often do it. Translation: " Surely you re taking me with you." Sometimes it s a solitary bark at the kitchen door after dinner. Translation: " You forgot my treat, Buster!" And sometimes its 100 barks in a row. Translation: "The mailman is here! The mailman is here! Cant you hear him attacking our house？" But I think I witnessed the ultimate dog communication technique years ago. It was a neighbor s dog. I cant remember the breed or name. All I remember is how bright she was. She had no need for Bow Lingual. Whenever frustrated with her family, which appeared to be quite often, she would stroll into the living room, turn her back to them and sit directly in front of the TV they were watching. And pee. No translation needed. And you need not be smart or rich to figure that out.

We can infer from the passage that sale of "The Dog Translator" in Japan______.

A．was considered a failure

B．was quite successful

C．was relatively satisfactory

D．was relatively unsatisfactory
