问答题The only solid pieces of scientific truth about which I feel totally confident is that we are profoundly ignorant about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It would have amazed the brightest minds of the 18th century Enlightenment to be told by any of us how little we know and how bewildering seems the way ahead. It is this sudden confrontation with the depth and scope of ignorance that represents the most significant contribution of the 20th century science to the human intellect. In earlier times, we either pretended to understand how things worked or ignored the problem, or simply made up stories to fill the gaps. Now that we have begun exploring in earnest, we are getting glimpses of how huge the questions are, and how far from being answered. It is not so bad being ignorant if you are totally ignorant; the hard thing is knowing in some detail the reality of ignorance, the worst spots and here and there the not-so-had spots.

问答题假日连锁店的住客们每年从它们的2638家分店中卷走50万条毛巾，酒店想知道这些毛巾后来的遭遇如何。不过，假日酒店并没有对顺手牵羊者兴师问罪的意思，只想让他们为一次全国性促销活动添砖加瓦。酒店宣布对这些客人实施特赦，条件是要他们讲出这些年中被拿走的那些毛巾都派上了什么用场。1．每收到一个故事，假日酒店就向一个慈善机构捐款1美元。这个机构是假日酒店在1986年成立的，目的就是帮助患有致命疾病的儿童。假日酒店品牌管理高级副总裁马克说：“这是件轻松愉快的事情，只不过是让人们站出来讲述自己的故事。如果他们心里因衣柜存有一条假日酒店毛巾而残留着些许愧疚感的话，这一来也就烟消云散了。”2．这家连锁店要求客人们将自己的故事放到酒店的网站上，然后评选出25个最佳故事，故事的主人将获得一条限量珍藏的假日酒店毛巾。网站已经收到了数百个故事。一名男子说他在墨西哥蒙特雷的假日酒店拿了一条毛巾作为蜜月夜晚的纪念，后来，伊人已去，毛巾犹存。3．其实，失去一条毛巾只会给酒店造成3美元的损失，但酒店并不介意客人拿走毛巾，而大多数客人也认为房价中已经包含了毛巾的费用。

问答题 Directions: Read the following passage carefully and then translate the underlined sentences into Chinese. Cancer is used generically for more than 100 different diseases, including malignant tumors of different sites such as breast, stomach, colon, lung and mouth. (1) {{U}}The disease arises principally as a consequence of individual exposure to the substances that cause cancer in what individuals inhale, eat and drink, or are exposed to in their personal or work environment.{{/U}} Personal habits, such as tobacco use, dietary and physical activity patterns--well as occupational and environmental conditions--rather than genetic factors, play the major roles in the development of cancer. Many of the chronic diseases risk and the diseases themselves overlap. In developed countries, cancer is the second-biggest cause of death after cardiovascular disease (CVD), and epidemiological evidence points to this trend emerging in the less developed world. This is particularly true in countries of "transition" or middle income countries such as in South America and Asia. Already more than half of all cancer cases occur in developing countries. There are approximately 20 million people living with cancer at the moment; by 2020 there will an estimated 30 million. And the impact is far greater than the number of cases alone would suggest. (2) {{U}}Regardless of prognosis, the initial diagnosis is often{{/U}} {{U}}perceived bv patients as life-threatening, with over one-third of sufferers experiencing clinical anxiety and depression.{{/U}} Cancer can also be profoundly distressing as well as economically disruptive to patients' families. The clinical care of cancer patients is a costly element in public health budgets. (3) {{U}}Dietary factors are estimated to account for approximately 30% of cancers in Western countries, making diet second only to tobacco as a preventable cause of cancer.{{/U}} This proportion is thought to be about 20% in developing countries and is projected to grow. As developing countries become urbanized, patterns of cancer, particularly those most strongly associated with diet and physical activity, tend to shift towards the patterns of economically developed countries. Cancer rates also change as populations move between countries and adopt different dietary patterns. The relative importance of cancers as a cause of death is increasing. The incidence of lung cancer and cancers of the colon and breast generally increases in parallel with economic development, as stomach cancer declines. Cancer is also strongly associated with social and economic status. Cancer risk factors are highest in groups with the least education. In addition, patients in the lower socioeconomic classes have consistently poorer survival rates than those in higher social class. In recent years, substantial evidence has pointed to the link from overweight and obesity, to many types of cancer such as breast and kidney. (4) {{U}}The composition of the diet is also important since fruit and vegetables may have a protective effect by decreasing the risk for some cancer types such as oral and gastric cancer.{{/U}} Regular physical activity has also been seen to have a protective effect in reducing the risk of breast cancer. High intake of preserved meat or red meat might be associated with increased risk of colorectal cancer. Another aspect of diet clearly related to cancer risk is the high consumption of alcoholic beverages, which convincingly increase the risk of oral cavity, liver and breast cancers. The wealth of knowledge that already exists about cancer risk factors provides obvious and ample scope for action to reduce the cancer burden of all countries. After tobacco, overweight and obesity seems to be the most important avoidable cause of cancer. (5) {{U}}Given that poor nutrition, physical inactivity, obesity, tobacco and alcohol are risk factors common to other chronic diseases such as CVD, type 2 diabetes, and respiratory diseases, conducting a cancer prevention program within the context of an integrated chronic disease prevention program would be an effective national strategy.{{/U}}

问答题被与自己的思想、信仰及兴趣相仿的人所吸引，那是很自然的事。同样，与体貌特征跟自己相仿的人相处，亦让人感到舒适。 您也许已经注意到生活和工作中紧密相处的人是如何在举止上趋于类同的。我们常常会不自觉地模仿我们所接近、所爱、所仰慕的人。因此，球迷会模仿某个运动员独有的耸肩行走的样子；一对情人连摇头的方式也相同；而雇员则会学他老板的习惯，也在思考问题时手指间玩弄一支笔。 有影响的人物并非在所有的情形中都有意识地觉察到这种仿效，但是这种仿效的存在会使他感到舒服。如果他确实察觉到别人的手势或动作与他一样，他会感到高兴，因为那意味着他对别人产生影响，他对这些人有吸引力。

问答题The sun heats the Earth"s surface unevenly causing differences in air pressure. It"s these differences that cause wind to flow over our planet"s surface. Scientists convert wind energy into electrical energy by using wind mills or wind turbines. The turbines take the movement of the air and convert it into mechanical energy. Each wind mill contains blades that are connected to a generator. The faster the blades spin the more energy that is produced by the generator. In areas that have constant winds, you will find wind farms and small, wind-driven generators. On these wind farms are hundreds of wind turbines capable of providing the electricity for entire communities. The small wind-driven generators are used for individual homes to produce electricity. Similar to solar energy, wind energy cannot be consistently used. There are areas around the world that do not have constant winds. In areas like windy mountain passes, the wind does not blow continuously. Therefore wind energy is only dependable for certain areas of the planet.

问答题When proprietary information is a concern, remember that nondisclosure agreements may be a part of one's specifications, and that firms may be evaluated based on their compliance. While vital technologies and product development plans must be protected, foreign sourcing partners must have adequate information to enable them to perform to specifications. If the information is simply too sensitive to share, that may be an argument for making the " make" decision rather than " buy" in considering outsourcing at the outset.
