23、 early rather than leave everything to the last minute.(2)It ought to be you rather than me that sign the letter. .1.D 根据句意 “ 虽然袁隆平是中国最著名的科学家之一，但他仍然认为自己是个农民，因为他在田间耕作，进行科学研究” 可知应选 D 项。 2 C “ for whom he has struggled for the past five decades ” 是介词 for whom 引导的定语从句， whom 作 struggled for 的宾语，本句中把 for
24、提前， whom 代指前面的 farmers。 3B 本句为复合句， what 引导宾语从句且在从句中作主语。句意为：袁隆平博士种植的是被称为 “ 超级杂交水稻 ”的稻种。 4A 根据句意 “ 1974 年，他成为世界上第一位种植高产水稻的农业先锋” 可知应选A 项。 5C句中 it 为形式宾语， possible 为宾语补足语， 不定式短语 to produce one-third moreof the crop in the same fields为真正的宾语。 6 C 根据句意 “ 那时，饥饿是许多农村地区面临的困扰” 可知选 C 项。 7 A 根据句意 “ 袁博士要在不增加土地面积的基
25、础上寻求增收稻谷的途径” 可知选A 项。 8 Drid.of 摆脱；除去。固定搭配。句意为：由于他的研究，联合国在消除世界饥饿的战斗中有了更多的方法。9 B 根据句意 “ 他觉得出名后搞科研就不那么自由了” 可知应选 B 项。 10 D根据句意 “ 于是，他拿出好几百万元帮助其他人进行农业科学研究” 可知应选 D 项。 .1.B词义猜测题。根据第一段第一句可知，Bollworms “ 棉铃虫 ” 是一种常见的棉花害虫，而第二句话说 young ones 以棉铃为食物， 因此可以推测young ones 指的是 bollworms的幼虫，故选 B 项。 2D细节理解题。 第一段第三句中 “Bt
26、is able to kill bollworms and some other pests. ”和第三段第二句中“ But.Bt cotton mayhelpcontrol bollworms in other crops growingnearby.” 表明， Bt 对其他植物也有影响，故D 项表述错误。 3B细节理解题。 根据第二段第二句可知，这种 Bt 基因改良的棉花可产生杀死棉铃虫的毒素，故 B 项表述正确。根据第三段第一句可知，棉铃虫也危害其他庄稼，故排除A项；第二段第一句表明 Bt cotton 是含有 Bt 基因的棉花，故排除C 项；根据第二段最后一句可知， Bt 棉花已用于实际生产，故排除D 项。 4 C 细节理解题。根据第四段第五句可知，Bt 棉铃虫并不能解决所有的昆虫问题，故 b 不符合原文意思，故选C 项。 5B主旨大意题。 本文主要围绕一种抗棉铃虫的棉花即Bt 棉花对环境和农业的好处以及它存在的不足展开讨论。4
