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】
