There is currently abroad a new wave of appreciation for breadth of knowledge. Curricula at universalities and colleges and programs in federal agencies extol （赞扬）the virtues of a broad education. For scientists who work in specialized jobs, it is a pleasure to escape in our spare tune to read broadly in fields distant from our own. Some of us have made interdisciplinary study in our occupation, which is no surprise, because much of the intellectual action in our society today lies at the interfaces between traditional disciplines. Environmental science is a good example, because it frequently requires us to be conversant in several different sciences and even some unscientific fields.Experiencing this breadth of knowledge is stimulating, but so is delving deeply into a subject. Both are wonderful experiences that are complementary practical and aesthetic （美学的）ways. They are like viewing the marvelous sculpture of knowledge in two different ways. Look at the sculpture from one perspective and you see the piece in its entirety, how its components connect to give it form, balance, and symmetry. From another viewpoint you see its detail, depth, and mass. There is no need to choose between these two perspectives in art. To do so would subtract from the totality of the figure.So it is with science. Sometimes we gaze through a subject and are reluctant to stop for too much detail. As chemists, we are fascinated by computer sciences or molecular genetics, but not enough to become an expert. Or we may be interested in an analytical technique but not enough to stay at its cutting edge. At other times, we become immersed in the detail of a subject and see its beauty in an entirely different way than when we browse. It is as if we penetrate the surface of the sculpture and pass through the crystal structure to the molecular level where the code for the entire structure is revealed.Unfortunately, in our zeal for breadth or depth, we often feel that it is necessary to diminish the value of the other. Specialists are sometimes ridiculed with names such as "nerd” or "technocrats”, generalists are often criticized for being too “soft” or knowing too little about any one thing. Both are ludicrous （可笑的）accusations that deny a part of the reality of environmental science. Let us not be divided by our passion for depth or breadth. The beauty that awaits us on either route is too precious to stifle, too wonderful to diminish by bickering （争吵）.1.From a broad education to interdisciplinary study, we can see （ ）.2.The commentator would say that the totality of the sculpture of knowledge （ ）.3.Just because we become engrossed in the detail of a subject, according to the comment, does not mean that we （ ）.4.It is commentator ’ s contention that neither specialists nor generalists （ ）.5.Which of the following can be the best title for the comment?

As the defining epidemic of a modern age notable for overconsumption and excess, obesity is hard to beat. The increased availability of high-fat, high sugar foods, along with more sedentary lifestyles, has helped push the number of obese people worldwide to beyond 400 million, and the number of overweight to more than 1.6 billion. By 2015, those figures are likely to grow to 700 million and 2.3 billion respectively, according to the World Health Organization. Given the health implications—increased risk of heart disease, stroke, diabetes and some cancers—anything that helps people avoid piling on the pounds must be a good thing, right?Those who agree will no doubt welcome the growing success of researchers striving to develop “diet pills” that provide a technical fix for those incapable of losing weight at any other way. Last week a study published in The Lancet showed that tesofensine, which works by inducing a sense of fullness, is twice as effective as any other drug at enabling patients to lose weight.There is no question that advances such as this are good news for those with a strong genetic predisposition to obesity. But for the rest of us it is dangerous to see treatment as a more effective solution than prevention. There are several reasons for this. For a start, the traditional ways of maintaining a safe weight, such as limiting what you eat, increase consumption of fruit and vegetables and taking more exercise, are beneficial for our health in many ways.Second, overindulgence in fatty foods has implications for the entire planet. Consider the deleterious environmental effects of the rising demand for meat. As demonstrated in our special issue on economic growth, technological fixes will not compensate for excessive consumption.Third, interfering with the brain circuits that control the desire for food can have an impact on other aspects of a person's personality and their mental and physical health.We need two approaches: more research into the genetics of obesity to understand why some people are more susceptible, and greater efforts to help people avoid eating their way to an early death. Cynics will say we’ve tried education and it hasn’t worked. That is defeatist: getting people to change their behavior takes time and effort, held back as we are by our biological tendency to eat more than we need, and by the food industry ’ s ruthless opportunism in exploiting that.Drugs will be the saving of a few—as a last resort. But the global obesity problem is one of lifestyle, and the solution must be too.1.In the first paragraph all the figures surrounding obesity reflect （ ）.2.When it comes to the recently reported diet pills, the author would say that （ ）.3.Which of the following can be referred to as the environmental perspective of the author’s argument?4.The author argues that we make greater efforts to help people fight against （ ）.5.Which of the following can be the best title for the passage?

Petrified wood consists of a wide variety of mineral including silica, silicates, carbonates, sulfates, sulfides, oxides, and phosphates. They all can per-mineralize wood to form petrified wood. However, petrified wood most commonly consists of silica in the form of either opal or chert. Silicified wood is usually found within one of two types of strata. First, it occurs within accumulations of volcanic ash, tuff, ad breccia, e.g. the petrified forests of Yellowstone National Park. Second, silicified wood also occurs within sands, silts, and muds deposited by rivers and streams that have hardened to sandstones, siltstones, and shale. The silicified wood found in Petrified Forest National Park in Arizona and the Miocene strata of Louisiana and Texas occur within such strata. It forms in these deposits, because of the presence of dissolved silica within the groundwater. The silica is derived from the dissolution of the volcanic material by the groundwater within the sediments. Within 10 and 40 million years, the opal of the silicified wood further dehydrates and crystallizes into microcrystalline quartz (chert). Factors such as temperature and pressure may speed or slow the process, but eventually the opal of the silicified wood becomes chert. During the change from opal to chert in silicified wood, the relict woody texture may either be retained or lost.In southwest Texas and into Louisiana, three types of silicified wood can be recognized. First, the “nondescript silicified wood” is one that possesses a recognizable woody structure. It is not identifiable without oriented thin sections, specialized references, and comparative material. Therefore, this type is best described just as “silicified wood”. The second type, “Palm Wood”, is a group of fossil woods that contain prominent rod-like structures within the regular grain of the silicified wood. Depending upon the angle at which they are cut by fracture, these rod-like structures show up as spots, tapering rods, or continuous lines. The third type is “massive silicified wood” in which the silicification of the wood, or subsequent transformation of silica gel to opal or chert, has obliterated any trace of the grain of the former wood. Because of its variable, massive nature and heterogeneous trace element composition, many investigators have often failed to recognize the nature of this material.1.What does the passage mainly discuss?2.Which of the following is commonly a part of petrified wood?3.The underlined word “strata” in Paragraph 1 is closet in meaning to （ ）.4.It can be inferred from the passage that which of the following is true of Yellowstone National Park?5.The underlined word “such” in Paragraph 1 refers to （ ）.6.The author mentions groundwater (the underlined word) in Paragraph 1 in order to（ ）.7.According to the passage, the opal of the silicified wood became chert because （ ）.8.In paragraph 2, the author discuss three types of silicified wood because （ ）.9.The underlined word “prominent” in Paragraph 2 is closet in meaning to （ ）.10.Which of the following is a description, rather than one of the three type of silicified wood?11.What is the reason why many investigators have often failed to recognize the third type of silicified wood?
We need to free young men from a destructive culture of manhood that impedes their capacity to feel other people’s hurt, to know other's sadness.
I have observed that the Americans show a less decided taste for general ideas than the French. This is especially true in politics.
Although the Americans infuse into their legislation far more general ideas than the English, and although they strive more than the latter to adjust the practice of affairs to theory, no political bodies in the United States have ever shown so much love for general ideas as the Constituent Assembly and the Convention in France. At no time has the American people laid hold on ideas of this kind with the passionate energy of the French people in the eighteenth century, or displayed the same blind confidence in the value and absolute truth of any theory.
This difference between the Americans and the French originates in several causes, but principally in the following one. The Americans are a democratic people who have always directed public affairs themselves. The French are a democratic people who for a long time could only speculate on the best manner of conducting them. The social condition of the French led them to conceive very general ideas on the subject of government, while their political constitution prevented them from correcting those ideas by experiment and from gradually detecting their insufficiency; whereas in America the two things constantly balance and correct each other.It may seem at first sight that this is very much opposed to what I have said before, that democratic nations derive their love of theory from the very excitement of their active life. A more attentive -examination will show that there is nothing contradictory in the proposition.
Men living in democratic countries eagerly lay hold of general ideas because they have but little leisure and because these ideas spare them the trouble of studying particulars. This is true, but it is only to be understood of those matters which are not the necessary and habitual subjects of their thoughts. Mercantile men will take up very eagerly, and without any dose scrutiny, all the general ideas on philosophy, politics, science, or the arts which may be presented to them; but for such as relate to commerce, they will not receive them without inquiry or adopt them without reserve. The same thing applies to statesman with regard to general ideas in politics.If, then, there is a subject upon which a democratic people is peculiarly liable to abandon itself, blindly and extravagantly, to general ideas, the best corrective that can be used will be to make that subject a part of their daily practical occupation. They will then be compelled to enter into details, and the details will teach them the weak points of the theory. This remedy may frequently be a painful one, but its effect is certain.
Thus it happens that the democratic institutions which compel every citizen to take a practical part in the government moderate that excessive taste for general theories in politics which the principle of equality suggests.
