标题: 请教 ku里的一道题 [打印本页] 作者: lyelfer 时间: 2010-9-21 10:40 标题: 请教 ku里的一道题 Editor: Articles in Gardening Magazine often spur sales of the plants they describe, particularly among people new to gardening. Accordingly, we will no longer publish articles or accept advertisements praising the beauty of rare wildflowers. Most such plants sold to gardeners have been difficult to propagate under cultivation, so plant sellers often collect them in the wild. Our new policy is part of our efforts to half this yearly plundering of our native plant populations.
Which of the following, if true, casts the most doubt on the wisdom of the magazine's new policy as a way of pursuing the intended effect ? (A) When people new to gardening buy plants, they often fail to take adequate care of the plants that they buy and become discourged from buying those varieties again. (B) Plant sellers who sell rare wildflowers have no reasonably inexpensive alternate way to offer their wares directly to new gardens. (C) The demand for rare wildflowers rarely exceeds the number of such plants that can be collected in the wild by plant sellers. (D) The propagation of rare wildflowers often depends on the plant's interaction with other organisms in their environment such as plants that create suitable soil conditions or insects and birds that disperse seeds. (E) Revenues from sales of plants collected in the wild are supporting the discovery of new low-cost techniques enabling rare wildflowers to be readily propagated in nurseries. 还有问support 的 ，这道题怎么理解呢？不是很懂，另外正确答案是什么呢？作者: lyelfer 时间: 2010-9-21 10:57

选E 说magazine广告刺激了rare wildflowers的销量。 措施是停止广告。 目的是要停止这种对rare wildflower的掠夺。 题目是削弱。
