同等學(xué)力英語輔導(dǎo) 每日一練（12月14日）

    When he died in April of 1993, Dr. Jeol Hiderbrand was 101 years old, had been married for seventy years, and had taught freshmen chemistry to over 40,000 students. In addition, he had published a popular textbook and dozens of articles, had managed the U. S. Olympic ski team, and had discovered a way to allow deep-sea divers to stay underwater longer. In his own way, Dr. Jeol Hiderbrand was certainly a genius.

    During that time, Dr. Jeol Hiderbrand discovered that the gas helium could be combined with oxygen for use as diving gas to allow divers to dive deeper and take the great pressure of the water without the physical discomforts that had been experienced when they used another gas, nitrogen. The use of helium for deep-sea diving is now standard practice.

    Dr. Jeol Hiderbrand was also valuable to his country during both World Wars. In World War I he analyzed the poisonous gases used on the battlefield and helped develop a truck that could clean and treat soldiers’ clothes which had been contaminated by poisonous gases during fighting.

答案
　　 1. D. 這篇短文主要介紹了美國一位將畢生奉獻(xiàn)給科學(xué)和教育的人Jeol Hiderbrand博士。答案可以從第一段看出：當(dāng)Jeol Hiderbrand博士101歲去世時(shí)，他已經(jīng)結(jié)婚七十五年了，In his own way, Dr. Jeol Hiderbrand was certainly a genius，最后一段也提供了這方面的線索：he could have such ageless energy and vigor。選項(xiàng)A. Dr. Jeol Hiderbrand’s discoveries and inventions, C. contributions to the world.太泛，太寬; B. Dr. Jeol Hiderbrand’s contributions to education他對(duì)教育的貢獻(xiàn)，太窄；均不是正確答案。

　　 2. C. 是什么原因使Jeol Hiderbrand博士對(duì)化學(xué)產(chǎn)生興趣呢？答案可以在第二段的陳述中找到。Jeol Hiderbrand博士對(duì)化學(xué)的興趣始于早年，上中學(xué)時(shí)就因其化學(xué)知識(shí)超過老師而聞名，并因此得到學(xué)校化學(xué)實(shí)驗(yàn)室的鑰匙。在學(xué)校化學(xué)實(shí)驗(yàn)室里他有了新的發(fā)現(xiàn)。文中引用Jeol Hiderbrand博士的話說，他對(duì)化學(xué)的興趣的形成是因?yàn)樗�很幸運(yùn)地出生在電視還未問世的時(shí)代，所以他得自己決定應(yīng)該關(guān)注什么。言外之意，當(dāng)今時(shí)代少兒沉湎于電視節(jié)目，實(shí)際上限制了個(gè)人興趣的發(fā)展。

　　 3. B. 是什么使 Dr. Jeol Hiderbrand 早在高中階段就與眾不同呢? 他在中學(xué)時(shí)就發(fā)現(xiàn)了某種化合物的正確的分子式，這使他與眾不同。C. 無從談起，D. 原文未提及，顯然應(yīng)排除。剩下的A. 和B. 需仔細(xì)斟酌。A.幾乎就是照抄原文，但有一字之差（key 而非keys），故不合題意。

　　 4. D.這是一道填充題。句子主語是“深海潛水中氦氣的使用”，所提供的幾個(gè)選項(xiàng)謂語A： “有助于克服潛水員使用氮?dú)鉂撍畷r(shí)身體的不適。” 此陳述與原文第三段第一句話意義相符；B: “是由Jeol Hiderbrand博士發(fā)現(xiàn)的”，也是正確陳述。再看C.，與原文第三段最后一句含義一致； 因此可見三項(xiàng)陳述都對(duì)。因此，正確D. All that is included in A, B, and C。

　　 5．D.遺傳。此題可根據(jù) Jeol Hiderbrand博士的幽默回答得出答案“I chose my ancestors carefully.”（我細(xì)心地選擇了自己的祖先）—－這就是他對(duì)自己長(zhǎng)壽不老，精力過人的見解。
