[GRE写作素材之机会主义者和竞争者.docxVIP

GRE写作素材之机会主义者和竞争者对于备考GRE的小伙伴来说，有充足丰富的写作素材，有利于在考生过程中找到灵感。就像一句话说的好，你要想说出一瓶水的知识，你肚子里面必须有一条河。这就说明了素材重要性。学习语言的人应该明白，表达能力和思想深度都考日积月累，潜移默化。从某种程度上来说，提高英语的写作能力，没有任何捷径可循。因此前程百利小编为大家准备一篇有关机会主义和竞争者的文章，一方面是希望考生你能够对这篇文章的好的表达方式加以记忆，另一方面也是激励考生，机会是留给有准备的人！Opportunists and CompetitorsGrowth, reproduction, and daily metabolism all require an organism to expend energy. The expenditure of energy is essentially a process of budgeting, just as finances are budgeted. If all of one’s money is spent on clothes, there may be none left to buy food or go to the movies. Similarly, a plant or animal cannot squander all its energy on growing a big body if none would be left over for reproduction, for this is the surest way to extinction.所有生物体都需要通过消耗能量来实现生长、繁殖和每日的新陈代谢。能量的消耗从根本上来说，是一个主体进行能量预算的过程，如同财政预算。如果一个人所有的钱都用来买衣服，可能就没钱购买食物或者看电影了。同样，动植物不能将所有的能量都浪费在生长巨大的躯体上，如果它们没有多余的能量用于繁殖，那么必将走向灭绝。1.metabolism [m?t?b?l?z(?)m] n. [生理] 新陈代谢2.expenditure [?kspend?t??; ek-] n. 支出，花费；经费，消费额3.budgeting [bud?iti?] n. 编制预算4.extinction [?kst??(k)?(?)n; ek-] n. 消失；消灭；废止All organisms, therefore, allocate energy to growth, reproduction, maintenance, and storage. No choice is involved; this allocation comes as part of the genetic package from the parents. Maintenance for a given body design of an organism is relatively constant. Storage is important, but ultimately that energy will be used for maintenance, reproduction, or growth. Therefore the principal differences in energy allocation are likely to be between growth and reproduction.因此，所有生物体都会将自己的能量进行分配用以生长、繁殖、维系生命和进行储备。它们没有选择，这种分配方式是来自上一代遗传基因的一部分。维系生命对于一个特定生物的身体设计是相对恒定的。储备很重要，但储备的能量最终都将被用于维系生命、繁殖或者生长。因此，能量分配上的主要不同就在于生长和繁殖之间。1.allocation [?l?ke??(?)n]n. 分配，配置；安置2.maintenance [me?nt(?)n?ns; -t?n-] n. 维护，维修；保持；生活费用Almost all of an organism’s energy can be diverted to reproduction, with very little allocated to building the body. Organisms at this extreme are “opportunists.” At the other extreme are “competitors,” almost all of whose resources are invested in building a huge
