听力原文： In spite of stories of prosperity in the United States, not only does poverty exist there, but crimes of various types have been increasing at an alarming rate. Most types of serious crime increased from 363.5 in every 100,000 people in 2003 to 535.5 in 2004. In that one year, there was one murder committed every 24 minutes, one case of robbery in every 10 minutes and one case of rape in every 7 minutes. The cases of murder involved 21,456 victims. Most acts of violence were committed by young people. 57% of the criminals arrested in 2004 were youths below 25 years of age. Everyone agrees that crime is partly a result of bad material conditions, poverty, lack of education, living without a settled home, being parentless, sufferings due to other kinds of misfortunes, etc. There are also other factors than material conditions which are responsible for the sharp increase of the crime rate. In the first place, some states have made laws approving the death penalty but some have not. Secondly, the constitution allows every citizen to carry weapons for his own protection. It is therefore possible aid easy for anyone in the country to get a gun. Finally, there has been too much violence shown on TV and too much violence reported in newspapers of all kinds. The details of the crimes are so accurately described that even children know how to repeat what they have seen or read. All these have resulted in a higher frequency of crimes committed both by professional criminals and by nonprofessional ones such as murder, drug smuggling, robbery, pocket-picking, etc. (33) A．The United States is faced with many social problems.

The first major energy transition was from wood to coal. For many centuries people used wood as a primary source of energy. By burning wood people were able to heat their homes, cook their food, and produce basic items. Most early societies grew up near a sufficient supply of wood. The main advantage of wood was that it was easy to get and easy to bum. During the early 1800's, some towns and villages began to make a transition from wood to coal as a basic source of energy, because they found that coal generally burns longer and at a higher temperature than wood, and a long-burning and hot-burning fuel was badly needed for the machines that were being used at that time. Another advantage of coal was that there was a lot of it and it was also easy to get. Besides, it could be easily shipped to faraway places. As a result of the transition from wood to coal, industry developed very rapidly. People were able to get more things and their standard of living went up. The second major energy transition was from coal to oil. We'll discuss it next week. Why did most early societies grow up near a sufficient supply of wood？ A．Because wood was safer than coal. B．Because wood burned longer than coal. C．Because there was more wood than coal. D．Because they used wood as primary source energy.

2. If man's mind cannot be turned into a logic-machine, neither can it function properly as a great emotional sponge, to be squeezed at will. All of us have known people who gush as a general response to life——who gush in seeing a sunset, who gush in reading a book, who gush in meeting a friend. They may seem to live by emotion alone, but their constant gushing is a disguise for absence of genuine feeling, a torrent rushing to fill a vacuum. It is not uncommon to find beneath the gush a cold, analytic mind that is astonishing in its meticulousness and ruthless in its calculation. Somewhere between machine and sponge lies the reality of the mind——a blend of reason and emotion, of actuality and imagination, of fact and feeling. 3. The entanglement is so complete, the mixture so thoroughly mixed, that it is probably impossible to achieve pure reason or pure reason or pure emotion, at least for any sustained period of time. 4. It is probably best to assume that all our reasoning is fused with our emotional commitments and beliefs, all our thoughts colored by feelings that lie deep within our psyches. Moreover, it is probably best to assume that this stream of emotion is not a poison, not even a taint, but is a positive life-source, a stream of psychic energy that animates and vitalizes our entire thought process. 5. The roots of reason are embedded in feelings——feelings that have formed and accumulated and developed over a lifetime of personality-shaping. These feelings are not for occasional using but are inescapable. To know what we think, we must know how we feel. It is feeling that shapes belief and forms opinion. It is feeling that directs the strategy of argument. It is our feelings, then, with which we must come to honorable terms.

When you choose not to eat breakfast, your body stays in slow gear. Also, people who skip breakfast often binge (无节制的大吃) later in the day at other meals or eat a high-calorie (高卡路里) snack in the morning. Breakfast eaters tend to eat less fat during the day， have more strength and endurance and better concentration and problem-solving ability. A good breakfast should provide up to 1/3 of your total calorie needs for the day. On the average, we eat 400 less calories for breakfast than for dinner. If breakfast doesn't appeal to you in the morning, try eating a lighter-dinner, earlier in the evening or save half your dinner for breakfast in the morning. If you still aren't hungry in the morning, start with something small like juice or toast or have a mid-morning snack later when you are hungry. Not eating breakfast can also cause you to overeat, since a fall in blood sugar often makes you feel very hungry later. To make matters worse, since your body is in a slowed state, it will not be able to burn those extra calories very efficiently. If you feed your body healthy snacks and meals throughout the day, you are less likely to become extremely hungry and stuff yourself as soon as you begin to eat. Since breakfast is the first and most important meal of the day, choosing the right fuel is important. The best breakfast foods are fruits, juice, lean meat, and grain products such as breads, rice, noodles, and cereals. 第36题：The word fast\" in the phrase \"break the fast\" in paragraph 2 means A．"a series of quick actions".
