Lesson 55 astronomy
第55課 天文學(xué)
Recent developments in astronomy may have madeit possible to detects in our own Milky Way and inother galaxies.
天文學(xué)的新發(fā)展使我們能夠在銀河系和其他星系發(fā)現(xiàn)行星。
The objective of astronomy is the exploration ofall phenomena outside the earth.
天文學(xué)探索地球以外的一切天體現(xiàn)象。
I took a course in astronomy at college.

relative
相對(duì)的
This is a major achievement because,in relative terms,planets are very small and do not emitlight.
這是一個(gè)重要的成就，因?yàn)橄鄬?duì)來說，行星體積小，而且不會(huì)發(fā)光。
What they have achieved is but relative success.
他們獲得的不過是相對(duì)意義上的成功。
This atmosphere of relative tranquility irated rather eased us.
這種相對(duì)的寧靜讓我們感到緊張而不是放松。
infinitely
無限地，無窮地
Finding planets is proving hard enough,but finding life on them will prove infinitely moredifficult.
發(fā)同行星已經(jīng)相當(dāng)艱難了，要在行星上發(fā)現(xiàn)生命簡(jiǎn)直是難上加難。
I have finally managed to find someone who is lazier,infinitely lazier than myself.
我終于找到了一個(gè)比我還懶——不知懶多少倍的人。
solar
太陽的
In our own solar system,for example,Venus is far too hot and Mars is far too cold to support life.
舉例來說，在我們的太陽系里，金星的溫度太高，火星的溫度又太低，生命無法生存。
Solar radiation is the least in the northern hemisphere in January.
北半球一月份太陽輻射小。
Venus
金星
Mars
火星
orbit
運(yùn)行軌道
Alternatively,if the star were small,
反之，如果恒星很小，
the life-supporting planet would have to have a close orbit round it
維持生命的行星就要在離恒星很遠(yuǎn)的軌道上運(yùn)行，
and also provide the perfect conditions for life forms to develop.
而且還要以生命形態(tài)提供極好的條件。
The earth moves in an approximately cirular orbit around the sun.
地球在一個(gè)近似正圓的軌道上繞著太陽運(yùn)行。
The planets occupy regular orbits in the space.
行星運(yùn)行的軌道空間位置是有一定規(guī)則的。
astronomical
天文學(xué)的，天文的
The development of such a telescopewill be one of the great astronomical projects of thetwenty-first century.
開發(fā)這樣的望遠(yuǎn)鏡將是21世紀(jì)天文學(xué)一個(gè)重要的研究課題。
Two standard astronmical techniques have been used in the search.
探索工作中使用了兩種標(biāo)準(zhǔn)的天文學(xué)技術(shù)。
The annual drug bill of the Health Services is mounting to astronomical figures.
衛(wèi)生部門的年度藥費(fèi)用快要達(dá)到了天文數(shù)字了。
generate
產(chǎn)生
Our own warm atmosphere and the heat generated by the telescope
地球周圍溫暖的大氣層和望遠(yuǎn)鏡散發(fā)出來的熱量
would make it impossible to detect objects as small as planets.
使得我們根本不可能找到比行星更小的物體。
The people attending the congress also generate more business in the hotel'srestaurants,bars,and shops.
參加會(huì)議的人還能為旅館的餐廳酒吧帶來更多的生意。
The pubications of the book generated voluminous research in social psychology.
這本書的出版導(dǎo)致社會(huì)心理學(xué)方面的研究的大力開展。
particle
微粒，粒子
Even a telescope in orbit round the earth,like the very successful Hubble telescope,
即使是把望遠(yuǎn)鏡放置在圍繞地球的軌道上——如非常成功的哈勃望遠(yuǎn)鏡——也不行。
would not be suitable because of the dust particles in our solar system.
因?yàn)樘栂抵杏袎m埃微粒。
This photo records the amazing beauty of dust particles floating in the sunlight.
這張照片記錄了在陽光中漂浮的塵埃微粒的驚人的美。
Virus particles differ in shape.
病毒微粒形狀不同。
Jupiter
A telescope would have to be as far away as the planet Jupiter
望遠(yuǎn)鏡要放置在像木星那樣遙遠(yuǎn)的行星上才有可能在外太空搜索生命，
to look for life in outer space,because the dust becomes thinner
因?yàn)槲覀冊(cè)绞墙咏栂档倪吘墸? the further we travel towards the outer edges of our own solar system.
塵埃越稀薄。
blot
遮(暗)
Once we detected a planet,
一旦找到這樣的一顆行星，
we would have to find a way of blotting out the light from its star,
我們就要設(shè)法將它的恒星射出的光線遮暗，
so that we would be able to'see' the planet properly and analyse its atmosphere.
這樣才能徹底‘看見’這顆行星并對(duì)它的大氣層進(jìn)行分析。
The dawn of peace is being blotted out.
和平的曙光被遮住了。
The cloud blotted out the sun but not for long.
云彩遮住了太陽，不過時(shí)間不長。
