SECTION B ENGLISH TO CHINESE Directions: Translate the following text into Chinese. Of the well-known ’five senses’--sight, hearing, smell, taste and touch--by far the most important to most animals is smell. But compared to other mammals, humans miss out. We have evolved to rely principally on sight and we are only gradually coming to understand what other animals can achieve by smell. In mammals, smells are detected by a thin layer of very sensitive cells in the nose called the olfactory epithelium (). Humans only have about five square centimeters of these cells, while an Alsatian dog, for example, has 150 square centimeters. This is why dogs continue to be used by man for everything from hunting wild animals to the search for hidden drugs.

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.

DreamsStudies show that in dreams things are seen and heard rather than thought. In terms

Dreams

Studies show that in dreams things are seen and heard rather than thought. In terms of the senses, visual experience is present in almost all dreams; auditory experience in 40 to 50 percent; and touch, taste, smell, and pain in a relatively small percentage. A considerable amount of emotion is commonly present, usually a pure and single emotion such as fear, anger, or joy

Two clearly distinguishable states of sleep exist. The first state, called NREM-sleep (non-rapid-eye-movement sleep), occupies most of the sleep period and is associated with a relatively low pulse and blood pressure, and few or no reports of dreaming. The second type of sleep, known as REM-sleep (rapid-eye-movement sleep) occurs cyclically during the sleep period with rapid eye movements and frequent dream reports. Typically, a person has four or five periods of REM-sleep during the night, whether the dreams are remembered often, rarely, or not at all; they occur at intervals of about 90 minutes and altogether make up about 25 percent of the night's sleep (as much as 50 percent in a newborn child). Evidence indicates that a dream period usually lasts from 5 to 20 minutes. Sounds and touches working on a dreamer can go into a dream if they occur during a REM-period. Although mental activity may be reported during NREM-sleep, these are usually short pieces of thoughtlike experiences.

Modern dream research has focused on two general interpretations of dream content. In one view, dreams have no meaning of their own but are simply a process by which the brain integrates new information into memories. In the other view, dreams contain real meaning symbolized in a picture language distinct from conscious logical thought. If dreams express important wishes, fears, concerns, and worries of the dreamer, the study and analysis of dreams can help reveal previously unknown aspects of a person's mental functioning.

There axe in general two opinions about what we experience in a dream:

A.one, we "see" our dreams, and two, we "think" our dreams.

B.one, we are happy, and two, we are angry.

C.one, dreams put new information into our memories, and two, dreams have real meanings in pictures different from our logical thinking.

D.we have pictures in dreams because one, we have slow eye movements, and two, we have rapid eye movements.
