【答案】
【小题1】D
【小题2】A
【小题3】B
【小题4】C
【解析】1．D．细节理解题．根据第三段中的"When the tree is blown sideways， its genes （基因） produce large numbers of sugar molecules （分子） to straighten the tree upwards．"及"Our study now shows that natural genetic changes are related to these differences．"可知，当杨柳被吹倾斜时，它的基因会产生大量的糖分子，使树向上伸直，也就是在大风中种植杨柳的基因会发生变化，故D项正确．
2．A．细节理解题．根据倒数第二段中的"They discovered that the Orkney trees produce five times the amount of sugars found in willows grown in sheltered conditions．"可知，奥克尼柳树生产的糖分是在遮风挡雨条件下生长的柳树的五倍，也就是非常富含糖分，故A项正确．
3．B．推理判断题．根据最后一段中的"The results show that biofuel crops such as willows could be grown in climatically changeable conditions where chances of growing food crops are limited"可知，结果表明，生物燃料科作物可以在气候多变、粮食作物生长机会有限的条件下种植，由此可知，生活在气候多变地区的农民被鼓励种植燃料科作物，故B项正确．
4．C．文章出处题．通读全文，特别是根据第一段可知，本文主要介绍了科学家通过研究发现倾斜种植的柳树可以增加生物燃料生产所需的糖分，属于科学研究范畴，最有可能出现在科学杂志上，故C项正确．
本文是一篇说明文，介绍了科学家通过研究发现倾斜种植的柳树可以增加生物燃料生产所需的糖分．
做这类题材阅读理解时要求考生对文章通读一遍，做题时结合原文和题目有针对性的找出相关语句进行仔细分析，结合选项选出正确答案．推理判断题也是要在抓住关键句子的基础上合理的分析才能得出正确答案，切忌胡乱猜测，一定要做到有理有据．
