Text 1Flying over a desert area in an airplane, two scientists looked down with trained eyes at treesand bushes. After an hour' s flight, one of the scientists wrote in his book, "Look here for probable metal. " Scientists in another airplane, flying over a mountain area, sent a message to other scientists on the ground, "Gold possible. " Walking across hilly ground, four scientists reported,"This ground should be searched for metal. " From an airplane over a hilly wasteland a scientistsent back by radio one word: "Uranium. "
None of the scientists had X-ray eyes: they had no magic power of looking down below theearth' s surface. They were merely putting to use one of the newest methods of locating minerals inthe ground... trees and plants as signs that certain minerals may lie beneath the ground on whichthe trees and plants are growing.
This newest method of searching for minerals is based on the fact that minerals deep in theearth may affect the kind of bushes and trees that grow in the surface.
At Watson Bar Greek, a brook(小溪) six thousand feet high in the mountains of British Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxes were filled with smallbranches from the trees. Roots were dug and put into boxes. Each bag and box was carefullymarked. In a scientific laboratory, the parts of the forest trees were burned to ashes and small part was examined to learn whether there were minerals in it.
Study of the roots, branches, and seeds showed no silver. But there were small amounts ofgold in the roots and a little less gold in the branches and seeds. The seeds growing nearest to thetree trunks had more gold than those growing on the ends of the branches.
26. Scientists were flying over a desert or a hilly wasteland or .a mountain area in order tosearch forin the ground.
A. gold
B. silver
C. uraniumD. minerals
27. The study of trees, branches and roots shows that
A. there were larger amounts of gold in the branches than in the seeds
B. there were smaller amounts of gold in the roots than in the branches
C. there were less amounts of gold in the seeds growing on the ends of branches than seeds growing nearest to the tree trunks
D. there was more gold in the branches than in the roots
28. Which is the best title suggested below?
A. Scientists Searching for Metals with Special Power
B. New Methods of Searching for Minerals
C. Gold Could Be Found by Trees and Plants
D. A New Method of Searching for Minerals--Using Trees and Plants
29. Which of the following is NOT mentioned as part of a tree that can help find minerals?
A. Leaves.
B. Roots.
C. Branches.
D. Seeds.
30. The scientists were searching for minerals by using
A. X-ray

參考譯文
坐著飛機飛過一片沙漠之地，兩位科學家用訓練有素的眼睛察看下面的樹木和灌木叢。經過大致一小時的飛行觀察後，其中一位科學家在他的本子上寫下這樣一句話“看這裡可能有金屬礦藏。”另一架飛機上的科學家們正飛過一座山區。他們給地面觀察站的科學家們發了“可能有金礦”的資訊。步行越過山地，四名科學家得出報告：“應該在此地尋找金屬礦藏”。從飛過多山丘的荒原的飛機上，一位科學家用無線電發回一個字：“鈾”。
沒有一個科學傢俱有x射線那樣的眼睛：他們並沒有看透地球表面的魔力。他們僅僅使用了一個最新的技術來定位地下的礦藏…樹木和植被長在地上，通過他們能顯示出某種埋藏在地下的礦物。
這項最新的尋找礦藏的技術是依據這樣一個事實，即處在地下的礦物會影響到地面上灌木和樹木的生長。
沃森巴溪是加拿大英屬哥倫比亞一座6，000英尺的山上的一條小溪。一隊礦藏搜尋小組收集了許多包樹木的種子;盒子裡盛滿了小樹枝。樹根也被挖掉放進盒子裡。每個包和盒子都被仔細標記了。在科學實驗室內，樹枝被燒成灰然後做檢測。檢查每個細小的部分是否含有礦藏。
對樹根、樹枝和種子的檢測並沒發現銀元素，但卻在樹根部發現了部分金元素，同時在樹枝和種子中也發現了較少的金元素。長在最接近樹幹上的種子要比長在樹枝根部的種子含金元素多一些。
答案及解析
26.D【解析】語義理解題。根據文章第一段的內容提到各種金屬，而這些金屬元素是包含在礦(mineral)裡的。故本題選擇D。
27.c【解析】細節題。從文中最後一句“The seeds growing nearest to the tree trunks had more gold than those growing on the ends of the branches.”(長在最接近樹幹上的種子比長在樹枝根部的種子要含有更多的金元素)可知答案。故本題選擇c。
28.D【解析】主旨題。通讀全文可知文章的大部分(第二至五段)都在講述通過植物來尋找礦藏。故本題選擇D。
29.A【解析】細節題。從最後一段可知，通過研究roots，branches和 seeds可判定地下是否有礦產，而leaves在文章中卻沒有提到。故本題選擇A。
30.D【解析】細節題。從文章第一段的第一句“two scientists looked down with trained eyes at trees and bushes”(兩位科學家用受過訓練的眼睛觀察樹木和灌木)可知答案。故本題選擇D。
Text 2The most frightening words in the English language are, "Our computer is down. " You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in the ticket office said, "I' m sorry, I can' t sell you a ticket. Our computer is down. "
"If your computer is down, just write me out a ticket. "
"I can' t write you out a ticket. The computer is the only one allowed to do so. "
I looked down on the computer and every passenger just standing there drinking coffee and staring at the black screen. Then I asked her, "What do all you people do?"
"We give the computer the information about your trip, and then it tells us whether you can fly with us or not. "
"So when it goes down, you go down with it. "
"That' s good, sir. "
"How long will the computer be down?" I wanted to know.
"I have no idea. Sometimes it' s down for 10 minutes, sometimes for two hours. There' s no way we can find out without asking the computer, and since it' s down it won' t answer us. "
After the girl told me they had no backup computer, I said. "Let' s forget the computer. What about your planes? They' re still flying, aren't they?"
"I couldn't tell without asking the computer. "
"Maybe I could just go to the gate and ask the pilot if he' s flying to Washington," I suggested.
"I wouldn't know what gate to send you to. Even if the pilot was going to Washington, he couldn't take you if you didn't have a ticket. "
"Is there any other airline flying to Washington within the next few hours?"
"I wouldn't know," she said, pointing at the dark screen. "Only ' IT' knows. It can' t tell me. "
By this time there were quite a few people standing in lines. The word soon spread to other travelers that the computer was down. Some people went white; some people started to cry and still others kicked their luggage.
31. The best title for the article is
A. When the Computer Is Down
B. The Most Frightening Words
C. The Computer of the Airport
D. Asking the Computer
32. What could the girl in the ticket office do for the passengers without asking the computer?
A. She could sell a ticket.
B. She could write out a ticket.
C. She could answer the passengers' questions.
D. She could do nothing.
33. why do you think they had not a backup computer?
A. Because it was easy down.
B. Because it was very expensive.
C. Because it was not advanced enough.
D. Because it was not as big as the main computer.
34. The last paragraph suggests that
A. a modern computer won' t be down

參考譯文
英語中最令人恐懼的句子是：“我們的.電腦宕機了。”在出差的時候，這樣的訊息你聽到的越來越多。前幾天我在機場排隊買去華盛頓的票。售票視窗的女孩說：“對不起，我們現在不能賣票。我們的電腦宕機了。”“要是電腦壞了，你就給我填一張票吧。”
“我無法給你填票。我們只能用電腦出票。”
我看著那臺電腦。乘客們都站在那裡，喝著咖啡，盯著那已黑了的螢幕。然後我問她：“你們這些人都是幹什麼的?”
“我們把你旅途的資訊輸入電腦，然後它就會顯示是否有合適你的航班。”
“所以要是電腦宕機了，你們就什麼都不能幹了。”
“是的。先生。”
“電腦宕機要持續多久?”我問道。
“我不清楚。有時十分鐘，有時兩個小時。要是不Pl電腦我們什麼資訊都不知道。既然現在它宕機了，它就不會迴應我們了。”
從女孩那裡得知沒有備用電腦後，我說：“我們先別管電腦這事。你們的飛機呢?它們還在飛，是嗎?”
“沒有電腦，我就無法回答你。”
“或許我可以去大門那問飛行員是否要飛往華盛頓。”我暗示道。
“我不知道讓你去哪個門找他。即使飛行員飛往華盛頓，要是沒有機票.他也不會讓你登機。”
“接下來的幾個小時還有其他去華盛頓的航班嗎?”
“我無法回答你，”她說著，順便指指那黑了的螢幕，“只有‘它'知道.而它現在無法告訴我。”
現在已經沒多少人排隊了。電腦宕機的訊息迅速傳到了其他旅行者那裡。一些人驚得臉都白了，有一些人開始大叫，還有一些人憤怒地踢他們的行李。
答案及解析31.A【解析】主旨題。根據文章第一句中的“0ur computer is down”(我們的電腦宕機了)及後面的文章關於機場電腦宕機後的一些對話內容可知，文章主要講述的是機場電腦宕機後發生的一些事情，故本題選擇A。
32.D【解析】細節題。根據文章中的對話“When it[computer]goes go down with it.”(若電腦宕機了，你們也工作不了 了。)可知，機場售票員什麼都不能做。故本題選擇D。
33.B【解析】主觀題。沒有備用電腦，最有可能是因為裝置比較貴。故本題選擇B。
34.C【解析】推斷題。根據文章最後一段的描述：電腦宕機，旅客們感到恐懼、憂鬱、不安，故本題選擇C。
35.B 【解析】細節題。文中第四段第一句“every passenger was just standing there drinking coffee and staring at the black screen.”(乘客們站在那兒，喝著咖啡，眼睛盯著那個黑掉了的螢幕)。
