Atomic Cars
Text I
1 Every motorist dreams of a car of the future that does not
have to be refueled every few hundred miles, a car that will
cost little to run because there is no outlay on petrol.
2 "Of course," you hear it said by an optimistic motorist,
"the answer is the atom. Harness atomic power in a car, and
you'll have no more worries about petrol. The thing will run
for years without a refill."
3 And, theoretically, he is right. The answer is the atom. If atomic
power could be used in a car, one small piece of uranium would keep
the engine running for twenty or more years. Of course, this would cut
the cost of running a car by quite a few hundred pounds, depending
upon how much you spend on petrol.
4 But is this science-fiction-like picture of the atom exploding
peacefully beneath the bonnet of a car possible?
In theory it is, since already the atom has been harnessed to drive submarines, and an atomic engine is already in existence. But, say the experts, there are many problems still to be conquered before such an engine can in fact be fixed into a car.
Text I
5 Now what exactly are these problems that stand between you
and a car that you will never have to refuel? Frankly, most of
them can be summed up in one word — radiation. An atomic
reactor, the kind of engine that would produce energy by atom-
splitting, throws off radiation, extremely dangerous radiation.
These rays are just as dangerous as when they are released from
an atomic bomb.
This radiation penetrates anything except the thickest concrete and lead, with fatal results for anybody in its path. Thus, at the moment any car carrying an atomic engine would also have to carry many tons of lead in order to prevent the radiation from escaping.
Text I
6 Since a car made up of tons of lead is rather impracticable, the only answer at the moment seems to be the discovery or invention of 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. Most likely this metal would have to be synthetic, since no natural metal
except lead has yet proved fit for the job. When this light metal is
invented, the motoring world will be well on the way to an atomic
car. However, even after the invention of a protective but light
metal, two other problems still remain, those of economics and
safety.
Text I
7 It is extremely doubtful whether at the beginning a really
economic engine could be made, that is, one cheap enough to
make it worth putting in a car. But it seems safe to say that
eventually, as techniques and mass production come in atomic
engines, the price will go down. This is basic economics, and
manufacturers should eventually be able to produce something
that will at least be cheaper than having to pay for petrol during
the lifetime of the car.
Text I
8 But then this third problem still remains, that of safety.
Suppose that there is a road accident involving one, or perhaps
two, atomic cars, and that the atomic reactor or its protective
covering were damaged. Any explosion would be equal to that
of a very small atomic bomb. The effects of such an explosion
would be felt for several miles around. As will be realized, this is
perhaps the biggest problem of all to overcome. Is it possible to
make an atomic engine that will be really safe in every
circumstance?
Text I
From an article in Ford Times
refuel vt. & vi.
outlay: (on, for) money spent for a purpose: E.g. House buyers usually have a large initial outlay on carpets and furniture.
v.tr. (及物动词) To supply again with fuel. …给 再加燃料
v.intr. (不及物动词) To take on a fresh supply of fuel.
…给 换新燃料
there is no outlay on petrol.
Please paraphrase this sentence:
You do not need to spend a lot of money on petrol.
Harness atomic power in a car, and you’ll have no more worries about petrol.
harness: v. 1.) a. to put a harness on (esp. a horse) b. to fasten together or fasten t
o a vehicle: E.g. I harnessed the horse to the cart / the oxen to the plough. 2.) to use (a natural force) to produce useful power: E.g. harness the limitless power of the sun(C,U) n. 马鞍,甲胄 E.g. a baby’s harness/ a safety harness
Practice speaking English more, and you’ll improve your oral English quickly.
Travel eastward from Shanghai, and you’ll gain an hour when you reach Tokyo.
theoretically: adv.
1.) in a theoretical way; not practically
E.g. First I’ll explain how it works theoretically, then I’ll give you
a practical demonstration.
2) according to theory but not really
E.g. Theoretically he’s in charge, but not in fact his secretary
takes all the decisions.
a metal lid over the front of a car: to look under the bonnet
bonnet: Br.E = hood ( AE )
Please paraphrase the sentence:
In theory it is, since already the atom has been harnessed to drive submarines, and an atomic engine is already in existence.
Theoretically it is, now that
atomic energy has been used to
drive submarines and atomic
engine has been made.
This radiation penetrates anything except the thickest concrete and lead, with fatal results for anybody in its path.
penetrate: v. 1.) (into, through) to enter, pass, cut, or force a way (into, through): E.g. The knife penetrated his stomach. The rain had penetrated right through (his clothes) to his skin. 2.) to see into or through: E.g. My eyes couldn’t penetrate the gloom. He had a false beard on, but we soon penetrated his disguise.(=recognized that it was him) 3) infml. To come to be understood: E.g. I heard what you said, but it didn’t penetrate.
This radiation penetrates anything except the thickest concrete and lead, with fatal results for anybody in its path.
fatal: adj.
1) (to, for) causing or resulting in death
E.g. a fatal accident / illness
(fig.) Marriage at this stage could be fatal to your career.
2) (informal) bring danger or ruin, or having
unpleasant results:
E.g. It’s fatal to stay up working late into the night; you
always feel terrible next day.
This radiation penetrates anything except the thickest concrete and lead, with fatal results for anybody in its path.
Please paraphrase this sentence:
This radiation passes through anything except the
thickest concrete and lead, will kill anybody standing
in the direction that it goes
Make up of
Consist of , be constituted, be composed of
Please translate the following sentence :
这个城市的人口由藏、汉两大民族构成。
The population of the city is made up of Tibetan and Han
nationalities.
synthetic
1) Produced by synthesis, especially not of natural origin.
【化学】 合成的:尤指由非天然原料制成的2) Not natural or genuine; artificial or contrived:
人造的:非天然的或非真的;人造的或不自然的: E.g. “counterfeit rhetoric that flourishes when passions are sy
nthetic” (George F. Will)
“ 当激情非真诚时,虚伪的辞令便滔滔不绝” ( 乔治 F.
威尔 )
…the motoring world will be well on the way to an atomic car.
…the automobile industry will make great progress in the
making of an atomic car.
Please paraphrase this sentence:
The effects of such an explosion would be felt for several miles around.
In various places for several miles around, people would be
affected by the results of such an explosion.
Please paraphrase this sentence:
1. Why is Sir Fred Hole’s book Energy and Extinction riveting? In what respects is it different from other books on the same subject? 2. What did Sir Fred Hoyle say was the only hope for the future? Do you agree with him? 3. For what purpose did Sir Fred Hoyle write the book Energy or Extinction? 4. What do you think is the reason for so much opposition to the development of nuclear reactors? 5.

That Isn’t Our Fault Mr. and Mrs. Williams got married when he was twenty-three, and she was twenty. Twenty-five years later, they had a big party, and a photographer came and took some photographs of them. Then the photographer gave Mrs. Williams a card and said, “They’ll be ready next Wednesday. You can get them from studio. ” “No, ”Mrs. Williams said, “please send them to us.” The photographs arrived a week later, but Mrs. Williams was not happy when she saw them. She got into her car and drove to the photographer’s studio. She went inside and said angrily, You took some photographs of me and my husband last week, but I’m not going to pay for them. ” “Oh, why not?” the photographer asked. “Because my husband looks like a monkey, ”Mrs. Williams said. “Well,”the photographer answered, “that isn’t our fault.
