23. A A Short History of Naming Hurricanes 第一段講的是颶風的命名問題。從沒有名字到有名字,從女性名字到男女名字。通篇對颶風名字的歷史做了一個小小的總結(jié)。
24. F Different Names for the Same Things 第二段講了來自不同地區(qū)的強大風擁有不同的名字。第一句話就點出颶風和臺風是同一種風。正面的告訴我們這段的主題。
25. D Huge Energy Stored in a Hurricane 第四段說了颶風中擁有強大的能量,作者在第二句明顯的表達了這一觀點。
26. C Difficulty in Forecasting the Course of a Hurricane 第一句話,開門見山的告訴了我們颶風預測是一件艱巨的任務(wù)。后面,對其進行了解釋。
27. C sex equality. 第一段:In 1979, realizing the sexist (性別歧視的) nature of such names, the lists were expanded to include both men and women.考慮到性別歧視問題,名單中出現(xiàn)了男性和女性的名字。
28. A the timely (及時的) discovery. 第六段:The biggest advance in early detection is continuous watch from weather satellites.這句話說了最明顯的進步就是通過天氣衛(wèi)星連續(xù)的近期觀察。
29. E the huge power. 第四段:The problem is that we don't know how to make such great energy work for us.前文一直描述颶風中蘊含的巨大能量,這句話表達了問題的關(guān)鍵就是無法利用其能量。側(cè)面的說明了科學家對這種能量非常感興趣。
30. F its uncertainly. 第五段:Predicting the path of a hurricane is one of the most difficult tasks for forecasters. It moves at a typical speed of 15 mph. But not always. Some storms may race along at twice this speed, then suddenly stop and remain in the same location in the ocean for several days. It can be maddening (發(fā)瘋的) if you live in a coastal area that may be hit.這段話描述了颶風的不確定性。所以,跟蹤颶風是一件非常困難的事情。
