Friends play an important part in our lives, and although we may take the friendship for granted, we often don’t clearly understand how we make friends. While we get on well with a number of people, we are usually friends with only a very few — for example, the average among students is about 6 per person. In all the cases of friendly relationships, two people like one another and enjoy being together, but beyond that, the degree of intimacy between them and the reasons for their shared interest vary enormously. As we get to know people we take into account things like age, race, economic condition, social position, and intelligence. Although these factors are not of prime importance, it is more difficult to get on with people when there is a marked difference in age and background.
Some friendly relationships can be kept on argument and discussion, but it is usual for close friends to have similar ideas and beliefs, to have attitudes and interests in common &

Public distrust of scientists stems in part from the blurring of boundaries between science and technology, between discovery and manufacture. Most governments, perhaps all governments, justify public expenditure on scientific research in terms of the economic benefits the scientific enterprise has brought in the past and will bring in the future. Politicians remind their voters of the splendid machines ’ our scientists’ have invented, the new drugs to relieve old ailments (病痛), and the new surgical equipment and techniques by which previously intractable (难治疗的) conditions may now be treated and lives saved. At the same time, the politicians demand of scientists that they tailor their research to ’economics needs’, that they award a higher priority to research proposals that are ’near the market’ and can be translated into the greatest return on investment in the shortest time. Dependent, as they are, on politicians for much of their funding, s
