1.直立行走 说一种 primate 可以在树上 uprightwalking( 我理解的就是直立行走),这种 primate 跟 chimpanzee human 有共同的 ancestor。所以呢:以前说的人(还是 ancestor?)是在适应了 grassland 之后才学会直立行走的说法是错误的。问 weaken F:primate 可以在树上 upright walking P:这种 primate 跟 chimpanzee human 有共同的 ancestor C:人在适应了 grassland 之后才学会直立行走的说法是错误的 Q:问削弱 思路:关联草原与直立行走 方向:人是先学会直立行走后才学会在树上行走的 2. Orcher 10000年前,那时候的人就开始用 orcher。离现在的年代稍微近一点(但是还是 prehistoric)的人用 orcher创造 artwork,所以得出结论:10000年前的人就开始创造艺术 问weaken F:10000年前,那时候的人就开始用 orcher P:orcher都是用来创造artwork的 C:10000年前的人就开始创造艺术 Q:问削弱 思路:寻找orcher的其他用途 方向:orcher也有其他用途,可以不用来创造artwork 3. Magazine Editor: Articles in Gardening Magazine often spur sales of theplants they describe, particularly among people new to gardening. Accordingly,we will no longer publish articles or accept advertisements praising the beautyof rare wildflowers. Most such plants sold to gardeners have been difficult topropagate under cultivation, so plant sellers often collect them in the wild.Our new policy is part of our efforts to halt this yearly plundering of ournative plant populations. Which of the following, if true, casts the most doubt on the wisdomof 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 takeadequate care of the plants that they buy and become discouraged from buyingthose varieties again. B. Plant sellers who sell rare wildflowers have no reasonablyinexpensive alternative way to offer their wares directly to new gardeners. C. The demand for rare wildflowers rarely exceeds the number of suchplants that can be collected in the wild by plant sellers. D. The propagation of rare wildflowers often depends on the plants'interaction with other organisms in their environment, such as plants thatcreate suitable soil conditions or insects and birds that disperse seeds. E. Revenues from sales of plants collected in the wild aresupporting the discovery of new low-cost techniques enabling rare wildflowersto be readily propagated in nurseries. F:刊登在园艺杂志上的文章能使得植物的销量增长,特别是在那些刚入门的人群中 P:大多数卖给种植人的植物都很难在他们的栽培下生长,所以植物卖家在野外采集它们。 C:不会再刊登关于珍稀野花的文章和接受相关的广告,这是停止掠夺本地植物资而做出的一部分努力。 Q:问削弱 思路:断开园艺杂志与买珍稀植物的联系 选项:A,无关;B,无关;C,珍稀植物求大于供,但无法削弱;D,讲这些珍稀野花的好处,但无法削弱;E,那些卖野花的收入使得低成本的野花室内栽培技术发展起来,说明有无法拒绝的好处,采摘动机仍然存在,对; |
