26. Although most people wish to live long lives, attempting to significantly extend the average human life span would be a mistake. If achieved, this would place an enormous burden on resources, lowering the quality of life for everyone.

题库原题::Although most people wish to live long lives, attempting to significantly extend the average human life span would be a mistake. If achieved, this would place an enormous burden on resources, lowering the quality of life for everyone.

观点:What if , by the end of this century, we could more than double average life-span to between 160 and 180? Given that possibility, these are the issues that should be thoroughly discussed and debated. At some point, the number of people may become so large that it exceeds the carrying capacity of the planet, making life miserable for the vast majority of humans (and impossible for other species), even sowing the seeds for our own destruction.

The quality of life for very old people may be severely diminished, if changing the boundaries of aging is not accompanied by reasonable health. Certain tissues and organs may deteriorate even as life-span is markedly prolonged, so people may live 140 years with ever –worsening sight, hearing, mental function, and musculoskeletal function. Meanwhile, we might be expected to work, support ourselves, and pay taxes until age 80, 90, 110 or older. Some of us will outlive our resources and spend our extended years live in poverty. This would likely create intense adversarial relations between younger and older persons as they compete for limited jobs and resources.

27. ai是讨论是否应该有国际协议限制所有国家对矿物质燃料的使用,因为矿物质燃料有害且有限。

“As fossil fuel is a kind of important and limited resources, International agreements should be make to require all countries to reduce their dependence on it.”

考古:说是fossil fuels很重要而且有限,所以应该全世界达成一致降低各国的消耗量

V3 The fossil energy are vital and limited. International agreement should be adopted for all countries to decrease the dependence on the fossil energy

V4 fossil fuel resources are vital and limited, international agreements should be adopted that would require all the nations reduce the use of fossil fuel.


1、首先,虽然不愿意,但仍然要承认,自私几乎是天性。self consideration优先。在没有广泛的行动时,每一个国家都不愿意在自己作出牺牲的同时,其他国家没有行动。这样不公平,也不可能达到。这时,领导的作用很重要。安排各国家工作,协调各国家活动。有一个行动的指导作用。function as the leader of the group.

2、而且,保护资源是全球的问题,指望单个国家作出牺牲是不够的。因为在全球化经济发展下,资源几乎是全球运转的。比如,美国会向中国进口木材等原料。所以需要合作。大的跨国公司在其中扮演重要的角色。比如,开发非洲的,有很多是欧洲的公司,跨国公司的举动会影响到很多国家的经济政策。nuclear weapons proliferation

by the same token, the problem of energy conservation transcends the national borders in that either all nations must cooperate, or all will suffer.

3、当然,这样是不够的,必须由各个国家充分地发挥主动的作用take positive action。因为资源是全人类的,每个国家都有责任并且都有必要。只有将统一领导与各国的积极性作用一起结合,才是最effective的方法。

Optional words:

Sacrifice/ expense/ offering/ cost

Conserve/ protect/ guard/ keep/ maintain

Thesis sentence:

To conserve the energy resources is a worldwide project, however, individual nations have been take the responsibilities of energy conservation initiatively without international leadership.


International leadership and worldwide cooperation play important roles in the protection of energy resources.

Evidence: OPEC is one of the best examples. OPEC, the Organization of Petroleum Exporting Countries, is an international organization of eleven developing countries that are heavily reliant on oil revenues as their main source of income. Since oil revenues are so vital for the economic development of these nations, they aim to bring stability and harmony to the oil market by adjusting their oil output to help ensure a balance between supply and demand. In the long run, the stabilized out-put help to cease the problem of over-refining and over utilization of oil energy.


It is not idealistic to expect the sacrifices necessary to conserve energy independently. Factors other than international leadership and world wide cooperation have driven individual nations to conserve energy. These countries conserve energy purely for their own benefit in the future.


Most nations in Europe have developed and used automobiles that are highly energy efficient.

Japan is a country naturally with nearly no energy resources, so it make great effort to conserve energy for future generations. An famous case is that Japan once brought crude oil from other countries and buried it under the sea .
