1. He works _______________(在倒數第二個辦公室).
2. The beauty of the lake is _______________(難以用語言形容).
3. ________________(一個人如果關在家裡)，a person cant know much about the world.
4. _______________(完成作業後)，they went to the library.
5. I found him ________________(被打得青一塊紫一塊).
答案與解析：
1. in the last office but one
but經常與表示最高階的形容詞或first，next，last等同連用，如：Some people say this nation is the cleverest but one in the whole world.(有人說，這個民族在全世界範圍內聰明才智排第二。)She was the last but one to come.(她是倒數第二個來的。)
2. beyond description
比起譯文not easy to describe in words，cannot be described by words，答案的'譯文顯然要精妙得多。beyond用作介詞時可以表示exceeding，out the reach of，即：超出(理解、範圍、眼界)之上。如：This passage is beyond my comprehension.(這篇文章超出了我的理解力。)I won t buy your radio set beyond my offer.(只要超出我出的價錢，我就不買你這臺收音機。)
3. Kept within houses
過去分詞短語作狀語表示條件，相當於一個條件狀語從句。Kept within houses要比If a person was kept within houses更簡潔明瞭，且可以避免前後句person的重複。請看下例：Given more time, I can also do it.(如果給我足夠時間，我也可以做此事。)過去分詞短語還可以作原因狀語、時間狀語、伴隨狀語等。考生應注意複習。如：Influenced by his ideas, she joined the revolution too.(作原因狀語)Heated，ice changes into water.(作條件狀語)He went there with great hope，but returned greatly disappointed.(表伴隨狀況)
4. Having finished their homework
我們知道，現在分詞在句中可以表示原因、時間、條件、結果等。本題考查了現在分詞短語作時間狀語的用法。由後半句可知， 完成作業 發生在 他們去圖書館 之前，因此，現在分詞短語需要用完成時態。如果分詞動作與謂語動詞動作同時發生，就用一般式，如：Seeing the picture，he couldn t help thinking of her. (一看到照片，他就禁不住想起她。)
5. beaten black and blue
本題考點有二：一是如何表達習語 青一塊紫一塊 ;二是過去分詞作賓語補足語的用法。過去分詞作賓語補足語改為被動語態時，可以省略to be，尤其是在like，want，order，wish後，如：I wish him driven away. = I wish him to be driven away。換成被動語態後就是：He is wished driven away.
