⑴ 新視野大學英語第四冊 unit7A The coming energy crisis
Two hundred years ago, the world experienced an energy revolution that launched the Instrial Age. Ever since then, with the rapid increase of population density, the instrialized world's thirst for energy has more than tripled. Petroleum and natural gas are exploited as versatile and high quality energy procts. Uranium is also tapped to fuel nuclear reactors and provide atomic energy.
兩百年前，全球經歷了一場能源革命，由此引發了工業時代的到來。從那時起，隨著人口密度的迅速增加，工業國家對於能源的需求成倍成倍增加。石油和天然氣被看作是用途多、質量好的能源產品而得到開發，而鈾也得以開發，為核反應堆提供燃料並供應原子能源。
Cheap energy is the lifeblood of human society. But there is a dark side to the near monopoly of non-renewable fossil fuels like coal, oil and natural gas， along with controversial uranium, to supply our growing energy demands.
廉價能源是人類社會的命脈。但是，幾乎壟斷煤炭、石油和天然氣等不可再生化石燃料，以及有爭議的鈾，以滿足我們日益增長的能源需求，還有一個陰暗面。
The supply of these fuels is physically limited, and their use threatens our health and environment. Multiple international treaties have been proposed to limit the use of fossil fuels for this very reason.
這些燃料的供應實際上是有限的，它們的使用威脅到我們的健康和環境。為此，已經提出了多項國際條約來限制化石燃料的使用。
Fears of global warming aside， burning fossil fuels releases chemicals and particulates that can cause breathing problems, cancer as well as brain and nerve damage. Nuclear energy, once hailed as"too cheap to meter"， has never been economically successful when all costs are factored in.
拋開對全球變暖的擔憂不談，燃燒化石燃料會釋放出化學物質和微粒，導致呼吸問題、癌症以及大腦和神經損傷。核能曾被譽為「太便宜，無法計量」，但如果將所有成本都考慮在內，它在經濟上從未取得成功。
Furthermore, public opinion polls show nuclear energy is too closely associated with disasters like the Chernobyl reactor meltdown and the Fukushima explosion, and with the danger that: rebel insurgents could do damage with the toxic waste.
此外，民意調查顯示，核能與切爾諾貝利（Chernobyl）反應堆熔毀和福島（Fukushima）爆炸等災難有著太密切的聯系，而且還存在著這樣的危險：反叛分子可能用有毒廢料造成破壞。
Inexpensive and seemingly abundant non-renewable energy from dead plants and extinct animals fueled the 20th century economy, but geologists, climatologists,environmentalists, and many others are warning that the honeymoon may soon be over.
從死去的植物和滅絕的動物身上獲得的廉價且看似豐富的不可再生能源推動了20世紀的經濟發展，但地質學家、氣候學家、環境學家和許多其他人警告說，蜜月可能很快就結束了。

Sticking to high moral standards is easier said than done. Once, a young British car sales manager
who had just finished courses on business ethics was sent to sell cars to an African country. The
negotiations had been going on for months without any real results．He was at his wits' end. Finallyxhe
hit upon a solution．One day he bought a popular novel and slipped a check of #20,000 in the book.
Then he presented it to the minister in charge of transportation. This minister examined its contents，
pretending he didn』t see the check at all．Then he said with a smile："Young man，I hear London is at
its best in May.」The sales manager, who was quick-witted, replied: "My company in London will be
most honored to welcome your visit！」A short time later, the deal was approved in London！
