1958 Ford Nucleon Concept
Back in 1958, the engineers at Ford envisioned a future filled with mobile nuclear reactors. They built this concept, the Ford Nucleon(福特核能车), to show the world their dream. The Nucleon would have a tiny reactor suspended between two pontoons(浮箱) at its rear(后备箱) good for 5,000 miles between “recharges.” So in addition to nuclear reactors rocketing up and down (上下运动) the nation’s highways, there would be radioactive way stations sprinkled across the landscape like the seeds of a Mad Max post apocalypse.

Nuclear Power
? Nuclear Power, electrical
power produced from energy released by controlled fission( 原子的 裂变)or fusion of atomic nuclei (核聚变)in a nuclear reaction. Mass is converted into energy, and the amount of released energy greatly exceeds(突出) that from chemical processes such as combustion(燃烧过程).
? The first experimental nuclear reactor was constructed in 1942 amid tight wartime secrecy in Chicago, Illinois, in the United States. A prototype(原型) reactor was demonstrated at Oak Ridge, Tennessee(田纳西州), in 1943, and by 1945 three fullscale(全面部署) reactors were in operation at Hanford, in Washington State. These were dedicated to plutonium (生产原子的钚)production for nuclear weapons; however, the first large-scale commercial reactor generating electrical power was started up in 1956 at Calder Hall, United Kingdom.
The nuclear reactor of China.
?
Nuclear power is now a wellestablished source of electricity worldwide. The most common types of reactor are light water reactors, mostly pressurized(加 压的) water reactors (PWRs压水 堆) together with boiling water reactors (BWRs沸水堆). Gascooled and heavy water reactors make up the rest. Worldwide there are currently about 430 reactors operating in 25 countries providing about 17 percent of the world’s electricity. Nuclear reactors are also used for propulsion(推进) of submarines and ships, and there are a number of prototype(原型) and experimental reactors around the world. At present, only a few experimental fusion reactors(核聚 变反应堆) exist, none of which produce usable amounts of electrical power.

Pre-reading Questions

  1. T (The technical term for the splitting of the atom is called "atomic fission"原子裂变.)
  2. T (The rays are radioactive and may also be called "radiation".)
  3. T
  4. F (Atomic energy has been used in power stations, in ships and rockets, but not in cars.)
  5. F (It would be both convenient to use and cheap to keep, because a small piece of uranium can keep the car running for many, many years.)
Questions
Answer the questions orally
  1. Explain the following in your own words.
  1) ... because there is no outlay on petrol.
  1.
  1) ... because there is no need to spend money on petrol.

  2) ... depending upon how much you spend on petrol.
  2) ... the amount of money you would save by using atomic power is determined by how much you spend on petrol.

  3) ... with fatal results for anybody in its path.
  3) If anyone happens to be in an area where there is radiation, it will cost him his life.

  4) ... a metal that will be strong enough to hold in the rays, but at the same time light enough for a vehicle to carry with ease and economy.
  4) ... the metal will be strong enough to prevent the rays from escaping but at the same time it will be so light in weight that any vehicle can carry it without too much difficulty and without costing too much money.

  5) But it seems safe to say that eventually, as techniques and mass production come in atom engine, the price will go down.
  5) We have every reason to say that when new techniques and methods are introduced and when atomic engines can be produced on a large scale, the price, as a result, will be lowered.

  6) ... in every circumstance.

  6) under all conditions

  2. What kind of structure is the sentence "Harness atomic power in a car, and you'll have no more worries about petrol" ? Can you give an example using this structure?
  2. The sentence may be reworded as "If you can harness atomic power in a car, you'll have no more worries about petrol". The structure Imperative sentence + and you'll is equivalent to a conditional sentence structure formed by If..., you'll...

  3. What is the function of the word say in the sentence "But, say the experts, there are many problems still to be conquered before such an engine can in fact be fixed into a car“.
  3. Say is the predicate verb谓语动词 of the subject experts. The clause say the experts is in inverted order. The statement following the clause is a kind of direct speech. This loose journalistic style makes the article colloquial口语的,会话的 and informal.
