Dahm of the University of Michigan in Ann Arbor4. In the future, engineers predict, airplanes equipped with scramjet engines could transport cargo quickly and cheaply to the brink of space. Such hypersonic jets could potentially carry passengers anywhere in the world in just a few hours. Out of the three experimental HyperX aircrafts built for NASA5, only one is now left. The agency has plans for another 11second hypersonic flight, this time at 10 times the speed of the sound. 詞匯： hypersonic /?ha?p??s?n?k/ adj. 超音速的 booster /?bu:st?/ n. 助推器 equator /???we?t?(r)/ n. 赤道 milestone /?ma?lst??n/ n. 里程碑 unmanned /??n?m?nd/ adj. 無人的 booster rocket 助推火箭 scramjet /?skr?md?et/ n. 超音速燃燒沖壓式 , cargo /?k?:???/ n. 貨物 噴氣發(fā)動(dòng)機(jī) brink /br?? k/ n. 邊 緣 bustion /k?m?b?st??n/ n. 燃燒 注釋： 1.

C 第一段告訴我們，因?yàn)楸嘲梢匝b許多東西，所以可以將雙手解放出來做其它事情：to free your hands to do other things. 2. A 第二段的第一句說， Lawrence C. Rome 及其同事們發(fā)明的這種背包，當(dāng)背著背包走路時(shí)，會(huì)有電能產(chǎn)生；該段最后一句告訴我們，背包的這種性能可減少背包的重量，因?yàn)椴槐財(cái)y帶備用電池。題句的意思與文章的意思不符，所以答案是 B。 3. A 題句表達(dá)的意思與第三段第二句所述的內(nèi)容相符。 5. Ronan Hickey…separated them into six fundamental whistle types and 32 different categories： Ronan Hickey 將嘯聲劃分為 6 大類 32 種 6. most = most categories 7. both sets of dolphins 是指 the Irish dolphins 和 the Welsh dolphins。這一說法與短文最后一段第三句所表達(dá)的意思相符。題句表達(dá)的意思與第一段第一句表達(dá)的內(nèi)容相符。又如： It’s not a matter of money (這不是個(gè)錢的問題。 ride 是“游樂場(chǎng)供人玩樂的乘坐式的活動(dòng)裝置”。 Channel Tunnel (常簡(jiǎn)稱為 Chunnel) 是連接英法兩國(guó)的海峽隧道。短文說地震殃及英格蘭東南部的肯特 郡部分地區(qū)，電力中斷，幾千名居民無電可用。這一內(nèi)容短文中找不到，故答案為 C。 7. A 短文第六段第一句說，全球每年發(fā)生強(qiáng)度為里氏 4 級(jí)左右的地震有幾千次，但是這種中等強(qiáng)度的地震英格蘭很少發(fā)生。題句表達(dá)的內(nèi)容短文中找不到，故答案為 C。 4. A 短文第四段第一句說科學(xué)家正在設(shè)法將嘯聲與海豚的行為特性聯(lián)系起來，其中也包括成年海豚與小海豚之間的聯(lián)絡(luò)這一行為。所以答案是 A。 4． B 第四段最后一句的意思是： Rome 計(jì)劃將這種背包商業(yè)化，即，推向市場(chǎng)。 4. Ann Arbor：美國(guó)密歇根州（ Michigan）的一個(gè)城市，華盛頓郡郡政府所在地，因密歇根大學(xué)而聞名。 4. D 文章的第六段中，密歇根大學(xué)的研究人員 Werner J. A. Dahm 說， Hyper X 的試飛成功只是研制一種新式快速飛機(jī)過程中的一個(gè)里程碑 （ a major milestone on the way to a new breed of very fast airplanes），而不是新型飛機(jī)的誕生。 練習(xí)： 1. What is Alvin?
