问题     Is the goal to make all of our paper from waste? It’s a【S1】______question. If we collect enough waste, could companies stop using wood altogether? The answer is no  but,【S2】______to popular belief, this is not a bad thing.
    Although【S3】______rates are higher than ever before, there isn’t enough to meet the growing demand--not even close. In addition to the fact that people still throw away a lot of【S4】______good paper, there’s also some ’that’s【S5】______and can’t be recycled (think pizza boxes), and lots that’s never thrown away at all (such as books, magazines and filed documents).
    Another issue is quality. Wood【S6】______can be recycled between five and seven times before they become too weak and fall apart--so companies have to keep【S7】______new fiber into the system. If you talk to designers and printers, they’ll also tell you that certain design applications can’t be met using paper with high recycled【S8】______.
    Recently, some environmentalists have also expressed their belief that using wood is the best way to【S9】______widespread forest abundance, because it sends a signal to the marketplace to plant more trees. Thanks to market demand, landowners have a clear incentive to keep lands【S10】______ instead of converting them for other uses such as agriculture.
