Another of the social sciences relying upon research is anthropology, the study of human beings and their culture. Anthropological theories also result from investigation into the characteristics of people and their products, which contributes to a better understanding of the patterns of human behaviors. In their systematic examination, researchers in all branches of anthropology follow the same basic steps. The method called participant observation is most widespread, although other techniques are used as well. At first, the anthropologist enters a community to gather information from members of their community through observations and conversations. The field worker takes copious notes and, later on, begins to pose hypotheses from these that will form the basis of further research. After specific hypotheses have been developed, the researcher gathers information to lest them, often in the form of surveys or recorded interviews. Finally, the anthropologist organizes will the information and evaluates the hypotheses in light of the data. The conclusions often form the basis of articles for scientific journals, books and lectures.

In 1798 the political economist Malthus predicted that in time mankind would face starvation, having outgrown the available food supplies. Today, a century and a half later, there are still experts who forecast the same global disaster unless urgent measures are taken to prevent it.By the end of the present century there may well be over five thousand million people living on this globe, an increase of over fifty percent of today's figure. In order to keep pace with this increase in mankind the farmers of the world would have to step up their production of food by at least two per cent every year. Such a rate of increase has never been maintained in any country by conventional methods of agriculture, despite modern mechanization and the widespread use of fertilizers. There are no large worthwhile reserves of potential farmland remaining, and good fertile land is continually being diverted to industrial use. Moreover, erosion of the soil takes a constant toll.Intensive research, carried out over many years in all manner of climatic conditions, has produced a revolutionary method of growing crops without using any soil at all. Hydroponics, as this technique is called, may well be the answer to all our food worries. Already it has accomplished wonders in producing huge crops. Hydroponics was once a complicated and expensive business; now it is well out of the experimental stage. Labor costs are far lower than when normal methods of agriculture are employed. In fact, it is a completely automatic system. There is no hard manual work, no digging or plowing, and no weeding to speak of .Yields can be far higher than they are in soil.1. Which of the following best sums up the whole passage?2. The phrase “having overgrown the available food supplies” in the first paragraph implies that（ ）.3.According to the author, 2 percent annual increase in the production of food can not be achieved. Which of the following is not the explanation he gave for the problem?4. Which of the following statements is not true of hydroponics?5. Judging from the passage, the most important advantage of hydroponics should be（ ）.
