Scientists are discussing ways to remove excess carbon dioxide from the atmosphere by increasing the amount that is absorbed by plant life. One plan to accomplish this is to establish giant floating seaweed farms in the oceans. When the seaweed plants die, they will be disposed of by being burned for fuel.
Which of the following, if true, would indicate the most serious weakness in the plan above?
分析A选项
分析B选项
分析C选项
分析D选项
分析E选项
科学家讨论增加植物吸收二氧化碳来减少过量二氧化碳。一个计划是建立巨大的浮动海藻田。海藻死后,被作为燃料烧掉当前版本由 hoho 更新于2017-03-10 13:46:18 感谢由 hoho 对此题目的解答所做出的贡献。
计划题 目标是减少二氧化碳,题目削弱目标
(A) 南半球某些地区没有充足的营养支持海藻田;some 无意义概率,排
(B) 海藻烧的时候,产生的二氧化碳和整个生命周期吸收的一样多;即没有减少二氧化碳,削弱目标,正确
(C) 即使海藻田有效,一些人不愿换用这种新燃料;some,无意义概率,无法判断影响多大,排
(D) 每年大约70亿吨二氧化碳被排入大气,但只有50亿吨被植物吸收了;说明植物还是减少了二氧化碳,增强目标,方向反,排
(E) 海藻田靠作为营养补充品比作为燃料更赚钱;赚钱,显然与目标无关,排。。
目的:减少二氧化碳
计划:建立巨大的浮动海藻田,增加植物吸收
问削弱。其实在题目当中有一句话:海藻死后,被作为燃料烧掉。就应该可以联想到燃烧会产生二氧化碳
A 一些地方没有充足的营养来支持巨大的浮动海藻田,无关,同时,some无意义概率
B 海藻烧的时候,产生的二氧化碳和整个生命周期吸收的一样多;即没有减少二氧化碳,削弱目标,正确
C 又出现了some,无意义。讨论人们愿不愿意用燃油,无关。
D 排放量当中的多少会被植物吸收,无关
E 海藻田怎么样会更挣钱,无关
选B

remove excess carbon dioxide from the atmosphere by increasing the amount that is absorbed by plant life.这个是目的。When the seaweed plants die, they will be disposed of by being burned for fuel.这个是措施。要削弱做个argument一般是提出措施而带来的劣势而导致结论的削弱(比如选项B:之后燃烧的二氧化碳等于所吸收的)
