新概念英语太空的探索作文译文

  听录音,然后回答以下问题。

  When will it be possible for us to think seriously about colonising Mars?

  The Moon is likely to become the industrial hub of the Solar System, supplying the rocket fuels for its ships, easily obtainable from the lunar rocks in the form of liquid oxygen. The reason lies in its gravity. Because the Moon has only an eightieth of the Earth's mass, it requires 97 percent less energy to travel the quarter of a million miles from the Moon to Earth-orbit than the 200 mile-journey from Earth's surface into orbit!

  This may sound fantastic, but it is easily calculated. To escape from the Earth in a rocket, one must travel at seven miles per second. The comparable speed from the Moon is only 1.5 miles per second. Because the gravity on the Moon's surface is only a sixth of Earth's (remember how easily the Apollo astronauts bounded along), it takes much less energy to accelerate to that 1.5 miles per second than it does on Earth. Moon-dwellers will be able to fly in space at only three per cent of the cost of similar journeys by their terrestrial cousins.

  Arthur C. Clark once suggested a revolutionary idea passes through three phases:

  1 'It's impossible -- don't waste my time.'

  2 'It's possible, but not worth doing.'

  3 'I said it was a good idea all along.'

  The idea of colonising Mars -- a world 160 times more distant than the Moon -- will move decisively from the second phase to the third, when a significant number of people are living permanently in space. Mars has an extraordinary fascination for would-be voyagers. America, Russia and Europe are filled with enthusiasts -- many of them serious and senior scientists -- who dream of sending people to it. Their aim is understandable. It is the one world in the Solar System that is most like the Earth. It is a world of red sandy deserts (hence its name -- the Red Planet), cloudless skies, savage sandstorms, chasms wider than the Grand Canyon and at least one mountain more than twice as tall as Everest. It seems ideal for settlement.

  【参考译文】

  月球很可能成为太阳系的工业中心。从月球上的岩石中很容易提炼出液态氧,作为航天飞船的燃料。其原因在于月球的重力。因为月球的重只有地球的1/8,因此,从月球到地球的25万英里所消耗的能量要比从地球表面进入地球轨道的200英里所耗能量少97%。

  这点听起来令人难以置信,但却很容易计算出来。要乘坐一枚火箭飞离地球,火箭的速度要达到每秒7英里,而从月球出发的相应速度史是每秒1.5英里。由于月球表面的重力仅是地球表面的1/6 -- 还记得阿波罗飞船中的宇航员累松地跳跃 -- 在月球上加速到每秒1.5英里比在地球上所用能源要少得多。月球居民在太空遨游的费用仅是地球上朋友飞越同样路所需费用的3%。

  亚瑟.C.克拉克曾提议,一种创新的想法要经过以下3个阶段:

  1 “根本不可能,不要浪费我的时间。”

  2 “可能,但不值得做。”

  3 “我一直说这是个好想法。”

  如果有相当数量的人永久性地住在太空,征服火星的计划 -- 一个比月球远160倍的星球 -- 就可以明确地从第2阶段进入第3阶段。火星对未来的星际旅客说有着特殊的魅力。美国、俄罗斯和欧洲都有许多热心此项事业的人 -- 其中的不少是认真和资深的科学家,他们一直梦想着把人送上火星。他们的目标是可以理解的。火星是太阳系里与地球最接近的一颗行星。这是一个红色沙漠的世界(因而得名:红色行星),无云的天空,凶猛的沙暴,比大峡谷还宽的裂缝,起码有一座山有珠穆朗玛峰的近两倍高。看起来,它很合适居住。

  1.hub n.(活动的)中心

  1.The Moon is likely to become the industrial hub of the Solar System, supplying the rocket fuels for its ships, easily obtainable from the lunar rocks in the form of liquid oxygen.

  supplying the rocket fuels for its ships是现在分词做状语。

  in the form of以……形式

  例句:The novel is cast in the form of a diary.

  这部小说是以日记的形式写的。

  Our soundings are displayed in the form of a graph.

  我们的调查结果已用图表列出。

  2.The reason lies in its gravity.

  lie in在于

  例句:All their hopes lie in him.

  他们把所有希望都寄托在他身上。

  The trouble lies in the engine.

  毛病出在引擎上。

  3.Because the Moon has only an eightieth of the Earth's mass, it requires 97 percent less energy to travel the quarter of a million miles from the Moon to Earth-orbit than the 200 mile-journey from Earth's surface into orbit!

  an eightieth of分数的表达方式。详见语法部分。

  4.To escape from the Earth in a rocket, one must travel at seven miles per second.

  To escape是目的状语,相当于in order to

  5.Because the gravity on the Moon's surface is only a sixth of Earth's (remember how easily the Apollo astronauts bounded along), it takes much less energy to accelerate to that 1.5 miles per second than it does on Earth.

  much less energy,much用来修饰比较级less。修饰比较是副词much的常见用法,“much 比较级”的意思是“更……”“……得多”。如:

  It’s much colder today than it was yesterday. 今天比昨天冷得多。

  It was much worse than I thought. 它比我想像的还要糟得多。

  We will be a much better football team next year. 明年我们将会成为一支更好的足球队。

  除此之外,much还可以修饰最高级

  much修饰最高级应置于最高级前的定冠词之前,而不是之后。“much the 最高级”的意思是“最最……”“绝对是最……”。如:

  This is much the most difficult. 这是最最难的。

  That’s much the best plan. 那绝对是最好的计划。

  Of the three boys Nick is much the cleverest. 这三个男孩中,尼克最最聪明。

  6.Russia and Europe are filled with enthusiasts -- many of them serious and senior scientists -- who dream of sending people to it.

  dream of梦见,梦想,向往,渴望

  例句:I never dreamed of such a thing.

  我从没梦想过这样的事情。

  I've long dreamed of paying a visit to the Great Wall.

  我一直渴望游览长城。

  破折号中间的句子是对前面的enthusiasts做补充说明,相当于插入语,除掉之后不会影响整个句子的完整性,只是使意思更加清楚。

  英语分数的表示法:

  一、用“基数词+序数词”表示

  分数在英语中通常是借助于基数词和序数词来共同表达的。其中基数词表示分子,序数词表示分母。

  如:

  1.The centimeter is one-tenth of the decimeter or one-hundredth of the meter.厘米是分米的十分之一,或者说是米的百分之一。

  2.However,the number of boys will bea third or less than the girls in the class.但是,班里男生的人数将比女生少三分之一或更少。

  从以上例子可以看出:分子除用one外,也可用a;如果分子大于1,分母要用复数形式。但是,1/2不能说a(one)second,而要说a(one)half。例如:

  3.The sum of one half,one third and one fourth of a certain number is 13.某数的1/2,1/3和1/4的和是13。 1/4和3/4可以说a(one)fourth和three fourths,但常用a quarter和three quarters表示。应该注意的是,分数修饰名词时,若该名词是不可数名词只能用单数;若是可数名词,用单数或复数均可。但是,若它们在句子中作主语,则谓语动词是用单数还是复数取决于名词,即与分数所修饰的名词保持一致。例如:

  4.Only one-fifth of air consists of oxygen.氧气只占空气的1/5。

  5.About two thirds of the students attendthe meeting.大约2/3的学生都参加了会议。

  带分数也是常见的英语数词表达。所谓带分数,实际上是“整数+分数”,表达时分而述之,只是整数部分与分数部分要用连词 and连接。当带分数修饰名词时,该名词通常是复数,但若名词置于整数one或a之后,则用单数。“带分数+名词”作主语时,谓语动词根据临近原则要用复数。例如:

  6.You should finish the work within one and a fourth hours.你应在1.25小时内完成工作。

  7.The atom breaks up in a minute and a quarter.原子在1.25分钟内裂变。

  二、用per cent等表示

  表示百分之一可以说one(a)hundredth,但更常用one percent或per cent,即用百分数表示法来表达。例如:

  8.Our bodies are 65percent water.我们人体含65%水分。

  9.Seventy-five percent of the earth'ssur- face is covered by water.地球表面的75%被水覆盖着。

  10.Eighty-five percent of the students in English department are girls.英语系85%的学生是女生。

  三、用part表示

  名词part有“……分之一”的意思,分子大于1时,part用复数。表示分数的结构一般有以下三种:

  (1)“基数词(或a)+序数词+part(s)” a hundred part百分之一

  (2)“基数词+part(s)+in+基数词” five parts in one thousand千分之五

  (3)“基数词+part(s)+per+基数词” one part per million百万分之一

  四、用“基数词+介词+基数词”表示

  借助介词表示分数,介词前的数词是分子,介词后的数词是分母。例如:

  11.Ninety-nine people out of a hundred,if they were asked who first found America, would answer Clumbus.如果要问是谁首先发现美洲,一百个人中有九十九个(百分之九十九)将回答是哥伦布。

  这种结构中的介词主要有in,out of,of以及to

  12.The map is drawn to a scale of one of ten thousand.这张地图是按万分之一的比例绘制的。

  1.The Moon is likely to become the industrial hub of the Solar System, supplying the rocket fuels fro its ships, easily obtainable from the lunar rocks in the from of liquid oxygen.

  月球很可能成为太阳系的工业中心。从月球上的岩石中很容易提炼出液态氧,作为航天飞船的燃料。

  2.The reason lies in its gravity.

  其原因在于月球的重力。

  3.This may sound fantastic, but it is easily calculated.

  这点听起来令人难以置信,但却很容易计算出来。

  4.it takes much less energy to accelerate to that 1.5 miles per second than it does on Earth.

  在月球上加速到每秒1.5英里比在地球上所用能源要少得多。

  5.Mars has an extraordinary fascination for would-be voyagers.

  火星对未来的星际旅客说有着特殊的魅力。
