　　Ⅲ. 閱讀理解

　　Linus Pauling, the only person who has won two undivided Nobel Prizes, was born in Portland, Oregon. He attended Washington High School but because of an unimportant detail he did not receive his diploma until 1962, long after he had received his Bachelor’s degree in chemical engineering from Oregon State College in 1922. He had chosen to study his major because he could get a good job with it.

　　He won the Nobel Prize for Chemistry in 1954 for his research into the nature of the chemical bond and its application to the explanation of the structure of complex substance. His interest in the “behavior” of molecules(分子)led him from physical chemistry to biological chemistry, especially of the human body. He began with proteins and their main parts, the amino acids(氨基酸), which are called the “building blocks of life” . In 1950, he constructed the first satisfactory model of a protein molecule, a discovery very important to the understanding of the living cell.

　　During World WarⅡ, Pauling was a member of the Research Board for National Security, for which he was awarded the Presidential Medal of Merit in 1948. However, the use of the atomic bomb near the end of the war turned Pauling in a new direction. Having long worked on the structure of molecules, he took an immediate interest in the deadly effects of nuclear fallout on human molecular structures.

　　From then on, Pauling protested the production of the hydrogen bombs and supported the prevention of the spread of nuclear weapons. Through his efforts, The Nuclear-Test-Ban Treaty, declaring all nuclear tests to be illegal except underground ones, came into effect on October 10, 1963, the same day Linus Pauling was awarded the Nobel Prize for Peace.

　　Ⅲ. 用30個詞左右概括閱讀理解大意

　　答案解析

　　Ⅰ. 1. 【解析】選B。考查expose的用法。句意:暴露于核輻射下哪怕很短的時間也可能影響到人體內的基因。be exposed to暴露于, 在句中用作主語, 故用動詞-ing形式。

　　2.【解析】選B。考查非謂語動詞。句意:當他三個小時后回來時, 他們仍坐在沙發上, 聚精會神地交談。be absorbed in為固定搭配, 意為 “專心于” , 所以此處應用absorb的過去分詞形式, 作伴隨狀語。

　　3.【解析】選D。考查動詞短語辨析。句意:出國旅游的想法的確吸引了許多中國人。這就是為什么每年都有更多的人申請護照的原因。appeal to對……有吸引力, 符合句意。stick to堅持; contribute to捐獻, 促成, 為……作貢獻; attend to處理, 對付, 照料。

　　【變式備選】

　　【解析】選C。句意:當我每次出國旅行回到公司時, 我總有很多事要處理。attend to處理。add to增加; stick to堅持; appeal to懇求, 請求; 吸引……, 這三項都不符合句意。

　　4.【解析】選A。句意:你最好把煙戒掉, 湯姆, 你應該知道, 很多疾病都與抽煙有關系。be linked to sth. 與某物有聯系, 符合句意。lead to “導致” , 一般不用于被動語態; blame多用于be to blame結構, 表示 “應該受到指責” 。

　　【變式備選】

　　You can see programs broadcast by any station because television stations around the country areby satellite.

　　A. linked

　　B. combined

　　5.【解析】選C。考查動詞詞義辨析。句意:給你治療咳嗽的那個大夫保證給你治好病。treat治療; cure治愈; treating you for your cough現在分詞短語作定語。

　　6.【解析】選C。be to blame表示 “應該受責備” , 從結構分析主語應當為the boy, 因此選C。

　　7.【解析】選A。考查動詞短語辨析。句意:我認為你需要些戶外鍛煉, 足夠的新鮮空氣有利于健康。contribute to有助于, 導致; devote to奉獻; apply to適用; adjust to調節以適應。

　　8.【解析】選A。考查動詞短語辨析。句意:——工人們在談論什么?——他們在討論那位老工人昨天在會上提出的想法。put forward提出, 符合句意。come up被提及, 發生; set off出發, 引起; bring out取出, 出版。

　　【變式備選】

　　The workers will go on strike if the demands theyare turned down.

　　A. put aside

　　B. put through

　　C. put forward

　　D. put away

　　9.【解析】選B。句意:單個的單詞可能有意義, 但是整個句子沒有意義。make sense有意義, 講得通, 符合句意。take effect生效; leave behind忘帶, 留下; let down放下, 使失望。

　　【變式備選】
