问答题 Section A
Put the following paragraph into Chinese.
Changes and developments in a science are determined by numerous causes. Every science grows from its past, and the state reached in a previous generation provides the starting point for the next. But no science is carried on in a vacuum, without reference to or contact with other sciences and the general atmosphere for learning. Scientists and men of learning are also men of their age and country, and they can't live independent of the culture. Besides its own past, the course of science is also affected by the social context of its contemporary world and the intellectual premises in it. Applications of the science and the expectations that others have of it may be a very important determinant of the direction of its growth and changes.
