A【解析】這是一篇記敘文。文章講述了Heiss在牧場中偶然拾到了一個鄰國女孩的愿望清單，而后努力找到了這個女孩，并且?guī)推鋵崿F(xiàn)了圣誕愿望的暖心故事，向讀者傳達(dá)著愛不分國界。24. 細(xì)節(jié)理解題。根據(jù)第一段中“Heiss walked toward it, and found on the grassland was a broken balloon with its string attached to a piece of paper.”（Heiss朝它走去，發(fā)現(xiàn)草地上有一個斷了的氣球，繩子系在一張紙上。）及第二段中““Dayami,” it read on one side, in a child39。s writing. It was a Christmas wish list, all in Spanish”（“Dayami，”它的一面寫著，是一個孩子的筆跡。這是一張圣誕愿望單，全是西班牙語）可知，當(dāng)Heiss在牧場里騎車時發(fā)現(xiàn)了一個破了的氣球，氣球里裝著一個孩子用西班牙語寫的圣誕節(jié)愿望清單，故選A。25. 詞句猜測題。根據(jù)第四段中“Heiss then posted about his quest on Facebook, attaching photos, hoping his friends in Nogales might know the girl39。s family.”（然后，Heiss在Facebook上發(fā)布了照片，希望他在諾加利斯的朋友們可能認(rèn)識女孩的家人）；和第五段中“Heiss worried that time was running out before Chirstmas.”（Heiss擔(dān)心在圣誕節(jié)前時間不多了），由此判斷，劃線詞所在的句子意思是幾天過去了，沒有任何線索。lead在此處指的是 “線索”，故選B。26. 細(xì)節(jié)理解題。根據(jù)倒數(shù)第二段中“Not wanting to disappoint the girls who still believed in Santa Claus, Heiss and his wife told them they were “Santa39。s helpers”.”（為了不讓那些仍然相信圣誕老人的女孩們失望，Heiss和他的妻子告訴她們，他們是“圣誕老人的助手”）可知，Heiss 設(shè)法找到了Dayami是因為他不想破壞了孩子們心中的圣誕老人，故選D。27. 推理判斷題。根據(jù)最后一段中“Heiss said. “We now have friends for life. And, for a day, that border fence with its wire melted away.””（Heiss說，“我們現(xiàn)在有了一生的朋友。有一天，帶著鐵絲的邊界圍欄融化了）可知，愛是沒有邊界，不分國界的，故選A。CBioluminescence, unlike other sources of light（the sun, fire, light bulbs）, which produce energy from heat, is defined as “the emission of light from living organisms（such as fireflies and bacteria）as the result of internal chemical reactions”. It is one of the wonders of nature that just about any of us can witness.While a few organisms can produce bioluminescent light outside of the oceans（think fireflies）, most of the bioluminescence going on is in salt water. In fact, the vast majority of bioluminescent organisms evolved in order to provide light in deep sea marine ecosystems—either to light up prey or as a warning against predators（捕食者）—far below sunlight39。s reach into the water column.Humans have been putting natural bioluminescence to work for a while—19th century coal miners would trap fireflies（instead of openflame candles or lanterns that could cause explosion）in jars to light their way. But nowadays researchers are hard at work synthesizing（合成）the chemical reactions behind bioluminescence for a range of modemday applications.Using bioluminescence to help cure disease is a big focus of some biomedical research panies, given the promise of using heatfree organic light to detect metastasizing（轉(zhuǎn)移的） cancer cells, stem cells, viruses or bacteria within living tissue. The military also has big hopes for applying the chemical reactions of bioluminescence to create light that won39。t cause the heatseeking sensory equipment of the enemy whether on land，at sea or in the sky. Some other practical applications of bioluminescence include an effort to connect genes from bioluminescent organisms into trees that would light up when the sun sets.While none of these “technologies” is yet ready to bee mainstream, it39。s good to know that the future looks bright.28. What exactly causes biolunninescence?A. Heat energy. B. Chemical reaction. C. Salt water. D. Living organism.29. Why did miners use fireflies instead of lanterns in the 19th century to light up?A. To ensure safety. B. To seek fort.C. To provide convenience D. To save money30. What may bioluminescence help to be used as?A. The heatseeking sensory equipment B. A simple cure for all kinds of diseases.C. An allnatural alternative to street lights. D. An effective viruskiller within living tissues.31. What is implied in the last paragraph?A. The good and bright future should be ours.B. Bioluminescence is widely used in our life.C. The technologies are good enough to apply.D. The search is on for the use of organic light sources.【答案】28. B 29. A 30. C 31. D【解析】這是一篇說明文。文章介紹了關(guān)于生物發(fā)光的研究以及其應(yīng)用。28. 細(xì)節(jié)理解題。根據(jù)第一段中“Bioluminescence, unlike other sources of light（the sun, fire, light bulbs）, which produce energy from heat, is defined as “the emission of light from living organisms（such as fireflies and bacteria）as the result of internal chemical reactions”.”（與其他光源(太陽、火、燈泡)不同，生物發(fā)光是生物體(如螢火蟲和細(xì)菌)內(nèi)部化學(xué)反應(yīng)產(chǎn)生的光發(fā)射）可知，化學(xué)反應(yīng)導(dǎo)致了生物發(fā)光。故選B。29. 細(xì)節(jié)理解題。根據(jù)第三段中“19th century coal miners would trap fireflies（instead of openflame candles or lanterns that could cause explosion）in jars to light their way. ”（19世紀(jì)的煤礦工人們用罐子誘捕螢火蟲(而不是可能導(dǎo)致爆炸的明火蠟燭或燈籠)來照亮他們的道路。）可知，用螢火蟲不會發(fā)生爆炸，保證安全。故選A。30. 細(xì)節(jié)理解題。根據(jù)第四段中“Some other practical applications of bioluminescence include an effort to connect genes from bioluminescent organisms into trees that would light up when the sun sets.”（生物發(fā)光的其他一些實際應(yīng)用包括努力將生物發(fā)光生物體的基因與樹木連接起來，這樣當(dāng)太陽落山時，它們就能發(fā)光。）可知，將生物發(fā)光運用在樹中，當(dāng)太陽落山后，樹木可以發(fā)光代替路燈使用。故選C。31. 推理判斷題。
