The pursuit of nothing but economic growth is illustrated by the response of the Japanese government to the American educational mission that visited Japan in 1947. After surveying Japan's educational program, the Americans suggested that the Japanese fill in their curriculum gap by creating departments in chemical and sanitary engineering. Immediately, chemical engineering departments were established in all the country's universities and technical institutions. In contrast, the recommendation to form. sanitary engineering departments was more or less ignored, because they could bring no profit. By 1960, only two second-rate universities, Kyoto and Hokkaido, were interested enough to open such departments. The reluctance to divert funds from production to conservation is explanation enough for a certain degree of pollution, but the situation was made worse by the type of technology the Japanese chose to adopt for their industrial expansion. For the most part, they simply copied American industrial methods. This meant that methods originally designed for use in a country that stretched from the Atlantic to the Pacific with lots of air and water to use as sewage receptacles were adopted for an area a fraction of the size. Moreover, the Japanese diet was much more dependent on water as a source of fish and as an input in the irrigation of rice; consequently discharged wastes built up much more rapidly, in the food chain.

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】Regardless of prognosis, the initial diagnosis is of- ten perceived by patients as life-threatening, with over one-third of sufferers experiencing clinical anxiety and depression. 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】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. 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】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. 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】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 withi

Negotiating is the process of communicating back and forth for the purpose of reaching an agreement. It involves persuasion and compromise, but in order to participate in either one, the negotiators must understand the ways in which people are persuaded and how compromise is reached within the culture of the negotiation. In many international business negotiations abroad, Americans are perceived as wealthy and impersonal. It often appears to the foreign negotiator that the American represents a large multi-million-dollar corporation that can afford to pay the price without bargaining further. The American negotiator's role becomes that of an impersonal supplier of information and cash. In studies of American negotiators abroad, several traits have been identified that may serve to confirm this stereotypical perception, while undermining the negotiator's position. Two traits in particular that cause cross-cultural misunderst anding are directness and impatience on the part of the American negotiator. Furthermore, American negotiators often insist on realizing short-term goals. Foreign negotiators, on the other hand, may value the relationship established between negotiators and may be willing to invest time in it for long-term benefits. In order to solidify the relationship, they may opt for indirect interactions without regard for the time involved in getting to know the other negotiator. Clearly, perceptions and differences in values affect the outcomes of negotiations and the success of negotiators. For Americans to play a more effective role in international business negotiations, they must put forth more effort to improve cross-cultural understanding. (1) What kind of manager is needed in present international business and foreign investment？ A、The man who represents a large multi-million-dollar corporation. B、The man with knowledge of foreign languages and skills in cross-cultural communication. C、The man who is wealthy and impersonal. D、The man who can negotiate with his foreign counterparts. (2) According to the passage, international business negotiation involves. A、short-term goals B、long-term benefits C、information and cash D、persuasion and compromise (3) In the foreign negotiators’eyes their American counterparts are.

B、American negotiator's directness and impatience cause cross-cultural misunderstanding. C、Americans has played a more effective role in international business negotiations.
