1、阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe. Previous studies have linked high exposure (暴露) to env
2、ironmental pollution to an increased risk of heart problems, but two analyses now show that poor air quality can lead to heart attack or stroke (中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物)
3、were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好) quality and relatively safe for our health can r
4、aise the risk of stroke as much as 34% within 12 to 14 hours of exposure. The authors of both studies stress that these risks are relatively small for healthy people and certainlymodest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of
5、these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health. 1. The text mainly discusses the relationship between.A
6、. heart problems and air qualityB. heart problems and exercisingC. heart problems and smokingD. heart problems and fatty food2. The underlined word“modest”in Paragraph 3 most probably means.A. relatively highB. extremely low C. relatively lowD. extremely high3. What can we learn from the text? A. Ea
7、ting fatty food has immediate effects on your heart. B. The EPA conducted many studies on air quality. C. Moderate air quality is more harmful than smoking. D. Stricter regulations on pollutants should be made. 4. The authors purpose of writing the text is most likely to.A. informB. persuade C. desc
8、ribeD. entertain【参考答案】14、ACDA社会生活类-阅读理解。You are given many opportunities in life to choose to be a victim or a creator. When you choose to be a victim, the world is a cold and difficult place. “They” did things to you which caused all of your pain and suffering. “They” are wrong and bad, and life is
9、 terrible as long as “they” are around. Or you may blame yourself for all your problems, thus internalizing (内化) your victimization. The truth is, your life is likely to stay that way as long as you feel a need to blame yourself or others. Those who choose to be creators look at life quite different
10、ly. They know there are individuals who might like to control their lives, but they dont let this get in the way. They know they have their weaknesses, yet they dont blame themselves when they fail. Whatever happens, they have choice in the matter. They believe their dance with each sacred(神圣的) mome
11、nt of life is a gift and that storms are a natural part of life which can bring the rain needed for emotional and spiritual growth. Victims and creators live in the same physical world and deal with many of the same physical realities, yet their experience of life is worlds apart. Victims relish (沉溺
12、) in anger, guilt, and other emotions that cause othersand even themselvesto feel like victims, too. Creators consciously choose love, inspiration, and other qualities which inspire not only themselves, but all around them. Both victims and creators always have choice to determine the direction of t
13、heir lives. In reality, all of us play the victim or the creator at various points in our lives. One person, on losing a job or a special relationship, may feel as if it is the end of the world and sink into terrible suffering for months, years, or even a lifetime. Another with the same experience m
14、ay choose to first experience the grief, then accept the loss and soon move on to be a powerful creative force in his life.

19、t the transformation from victims to creators. 【参考答案】39.ACBAD 阅读理解。Wind is the great maker of waves. There are exceptions, such as the tidal (潮汐的) waves sometimes produced by earthquakes under the sea. But the waves most of us know are produced by winds blowing over the sea.Now before constructing a
20、n imaginary life history of a typical wave, we need to know certain physical things about it. A wave has height, from trough (low point) to crest (high Point). It has long-the distance from this crest to that of the following wave. The period of the wave means the time it takes for succeeding crests
21、 to pass a fixed point. None of these things stays the same-for all depend upon the wind, upon the depth of the water and many other matters.The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but re
22、turns very nearly to its original position. And it is fortunate that this is so. For if the huge masses of water that make up a wave actually moved across the sea, sailing would be impossible.If we want to find the speed of a wave, we may use the following way:Speed = wavelength frequencyHere, wavel
23、ength is the distance between two high points (crests), frequency means the number of cycles per second 1. What causes waves?A. Earthquakes and nothing else. B. Only wind.C. Wind causes most waves. D. Wind causes some waves.答案解析：答案为C。本题为细节题。由第一段的最后一句话 “But the waves most of us know are produced by w
24、inds blowing over the sea.” 可知，答案为C。2. Which of the following is true according to the passage?A. The water of a wave moves away across the sea.B. The water of a wave remains almost at the same place.C. The water of a wave goes with the passing of the wave.D. The length of a wave means the distance
25、from the top of a wave to the bottom.答案解析：答案为B。本题为细节题。从第三段 “The water that makes up a wave does not advance with it across the sea. Each drop of water turns around in a little circle with the passing of the wave, but returns very nearly to its original position.” 可知，组成波的水并不随着波的前进而前进，每一滴水随着波的前进形成了一个小
26、圆圈，但是几乎回到原位置。故A，C错误，B选项正确。最后一段提到 “Here, wavelength is the distance between two high points (crests)”, 故答案D错误。3. The speed of Wave 1 is 100 cm/s, frequency 10. The frequency of Wave 2 is 300, while its speed is twice that of Wave 1. Which of the following is right?A. The wavelengths of the two are eq
27、ual.B. The wavelength of Wave 1 is 10 times longer than that of Wave 2.C. The wavelength of Wave 2 is longer than that of Wave 1.D. The wavelength of Wave 1 is longer than that of Wave 2.答案解析：答案为D。本题为计算题。按照后文提到的公式 “Speed = wavelength frequency” 即可计算出答案为D。完形填空。阅读下面短文，掌握其大意，然后从各题所给的A、B、C和D项中，选出最佳选项。 A
