    Lesson 61:Trouble with the Hubble
               哈勃望遠(yuǎn)鏡的困境

        First listen and then answer the question.
        聽錄音,然后回答以下問題。
        What is the special importance of a telescope in space?

        The Hubble telescope was launched into space by NASA on April 20,1990 at a cost of over a billion dollars. Right from the start there was trouble with the Hubble. The pictures it sent us were very disappointing because its main mirror was faulty! NASA is now going to put the telescope right, so it will soon be sending up four astronauts to repair it. The shuttle Endeavour will be taking the astronauts to the Hubble. A robot-arm from the Endeavour will grab the telescope and hold it while the astronauts make the necessary repairs. Of course, the Hubble is above the earth's atmosphere, so it will soon be sending us the clearest pictures of the stars and distant galaxies that we have ever seen. The Hubble will tell us a great deal about the age and size of the universe. By the time you read this, the Hubble's eagle eye will have sent us thousands and thousands of wonderful pictures.

    參考譯文

        哈勃望遠(yuǎn)鏡于1990年4月20日由國家航空航天局發(fā)射升空,耗資10多億美元。從最開始哈勃望遠(yuǎn)鏡就有問題。它傳送給我們的圖像很令人失望,因?yàn)樗闹饕R子有誤差。國家航天局準(zhǔn)備糾正這一錯(cuò)誤,為此將把4名宇航員送入太空修復(fù)望遠(yuǎn)鏡。“奮進(jìn)”號(hào)航天飛機(jī)將把宇航員送上哈勃。當(dāng)宇航員進(jìn)行必要的修復(fù)工作時(shí),“奮進(jìn)”號(hào)上的一只機(jī)器手將抓住望遠(yuǎn)鏡并托住它。當(dāng)然,哈勃位于地球的大氣層之外,因此,它很快就會(huì)給我們傳送我們所見到過的、有關(guān)行星和遠(yuǎn)距離星系的最清晰的照片。哈勃將告訴我們有關(guān)宇宙的年齡和大小的許多事情。等到你讀到這篇文章時(shí),敏銳的哈勃望遠(yuǎn)鏡已經(jīng)為我們送來了成千上萬張精彩的照片。

     

    自學(xué)導(dǎo)讀
      1.a(chǎn)t a cost of,造價(jià)為……,耗資,以……的價(jià)格/費(fèi)用。
      He has just built a new house for his family at a cost of £10,000.
      他剛為他的家庭蓋了一座新房子,耗資1萬英鎊。
      2.Right from the start there was trouble with the Hubble. 從最開始哈勃望遠(yuǎn)鏡就有問題。
      (1)start為名詞,表示“開始”、“開端”,from the start表示“從開始時(shí)”,副詞right起強(qiáng)調(diào)作用:
      He didn't want to work at the firm(right) from the start.
      他從最開始就不想在這家公司上班。
      (2)trouble在這里指“(機(jī)器等的)故障”、“問題”:
      There is (engine) trouble with my car.
      我的汽車(發(fā)動(dòng)機(jī))有問題。
      (3)the Hubble代指 the Hubble telescope。由于上下文中沒有其他以 Hubble命名的東西,前面又提到過一次Hubble telescope,所以用 the Hubble既簡潔又不會(huì)引起誤解。
      3.NASA is now going to put the telescope right…國家航天局準(zhǔn)備糾正這一錯(cuò)誤……
      put right表示“修好(故障等)”、“校正”、“糾正”等:
      Have you put the watch/clock right?
      你把表/鐘對(duì)好了嗎?
      Remember to put the lights right tomorrow.
      明天記得把燈修好。
      4.…the Hubble is above the earth's atmosphere, so it will soon be sending us the clearest pictures of the stars and distant galaxies that we have ever seen.……哈勃位于地球的大氣層之外,因此,它很快就會(huì)給我們傳送我們所見到過的、有關(guān)恒星和遠(yuǎn)距離星系的最清晰的照片。
      (1)關(guān)系從句that we have ever seen修飾pictures。
      (2)由于哈勃望遠(yuǎn)鏡位于大氣層之外,它照相便不受大氣的阻擋,因此照片清晰。
      (3)形容詞最高級(jí)后面的關(guān)系從句常用…ever heard, met, read,seen等完成式:
      This is the longest book (that) I have ever read.
      這是我所看過的書中最長的一部。
      Ian is the most interesting man (that/whom) I have ever met.
      伊恩是我所遇見的最有趣的人。
      5.…the Hubble's eagle eye will have sent us thousands and thousands of wonderful pictures.……敏銳的哈勃望遠(yuǎn)鏡將已經(jīng)為我們送來了成千上萬張精彩的照片。
      (1)eagle eye的含義是“鷹眼”、“銳利目光”:
      His father's eagle eye is always on him.
      他父親的銳利目光總是盯著他。
      (2)在表示“幾千”、“數(shù)千”、“許許多多”、“成千上萬”這些數(shù)字概念時(shí)可用thousands(of…):
      There are hundreds of thousands/thousands and thou
      sands of cars in this city.
      這座城市里有成千上萬輛汽車。

      他們明天就要到達(dá)此地。
      在第37課的語法中,我們學(xué)習(xí)了將來完成時(shí)。它用于表示到將來某一時(shí)刻已經(jīng)完成的動(dòng)作,必須和某個(gè)時(shí)間狀語連用:

      (2)將來完成進(jìn)行時(shí)表示某種狀況一直持續(xù)到說話人所提及的時(shí)間:
      By this time next week, I will have been working for this firm for twenty years.
      到下星期此刻,我就已經(jīng)為這家公司工作了20年了。
      在時(shí)間狀語從句中,要用現(xiàn)在完成時(shí)代替將來完成時(shí)(cf.第60課語法):

      1.cost(n.), price(n.)與value(n.)
      cost和price都可以表示“價(jià)格”、“價(jià)錢”,但price側(cè)重于指某個(gè)具體東西或商品的價(jià)錢,cost側(cè)重指某項(xiàng)服務(wù)、工程等的費(fèi)用:
      What's the price of the dress, please?
      請(qǐng)問這件衣服多少錢?(詢問價(jià)錢時(shí),price與what連用,不用 how much)
      They built the bridge at a cost of over £600,000.

      His values are different from those of mine.
      他的價(jià)值觀與我的不一樣。
      2.cost(v.), price(v.)與value(v.)
      cost為及物動(dòng)詞,表示“價(jià)錢為”、“(使)花費(fèi)”(不用于被動(dòng)語態(tài)):
