问题    The word conservation has a thrifty meaning. To conserve is to save and
protect, to leave what we ourselves enjoy in such good condition as others 【S1】______
may also share the enjoyment. Our forefathers had no idea that human population
would increase faster than the supplies of crude materials. Most of them, even 【S2】______
until very recently, have the foolish idea that the treasures were "limitless"
and "inexhaustible". Most of the citizens of early generations knew little or【S3】_____
nothing about the complicated and the delicate system that runs all through the
nature, which means that, as in a life body, an unhealthy condition of one part 【S4】______
will sooner or later be harmful to all others. 【S5】______
   Fifty years ago nature study was not part of the school work. Scientific 【S6】______
forestry was a new idea: timber was still cheap at that time because it could be
brought in any quantity from distant woodlands: soil destruction and river floods
were not national problems: nobody had already studied long-term climate cycles 【S7】______
in relation with proper land use: even the word conservation had nothing of the 【S8】______
meaning that it has for us today.
   For the sake of ourselves and those who come after us, we must now set about 【S9】______
repairing the mistakes of our forefathers. Conservation should, however, be made 【S10】______
a part of everyone’s daily life. To know about the water table in the ground is
just as important to us as a knowledge of the basic arithmetic formulas. [br] 【S7】

答案 already—yet

解析 用词错误。already用在肯定句中,yet一般多用在否定句或含否定含义的句子中。从否定主语nobody可知,应改already为yet。
