　　[答案及解析]

　　此类题型其实是完形填空的一种，其答题策略和解答四选一的完形填空大致一样，完形先完意是根本，所以解题应该是在通读全文、理解文章的主要内容、把握文章的框架结构的基础上进行。这类题型的一个特点是给出的单词词性不一，所以答题时除了从文章角度考虑之外，还应该分析句子的句法结构。从一定程度上来说，这类题目比常规的完形要更容易解答，因为语法指向比意义指向更明显。

　　本篇材料首句设问，给出话题和谈论的方向。第1段提出和介绍理论：All of these are influenced by the interaction of your genes and the environment in which you were

　　1

　　.第2段中首句有controversial，这是个关键词。其后的大量内容围绕此句展开，结尾用undeveloped photographs作比喻，并得出结论。

　　1、M

　　raise在这里的意思是“养育”，the environment in which you were raised的意思是“你被养育的环境”。

　　2、L

　　psychological activity的意思是“心理活动”，全句的意思是：研究基因和外部环境如何相互作用从而影响人心理活动的学科被称为行为遗传学。

　　3、E

　　make contributions to 为固定搭配，意为“为……作贡献”。本句意为：行为基因学为生物革命作出了重要的贡献。

　　4、A

　　ability to…意思是“做某事的能力”，此句可以简化成Any research is controversial，全句的意思是：任何一种暗示人类做出某种行为的能力是基于生物学的研究都是有争议的。

　　5、B

　　what you can achieve是宾语从句，limitations to what you can achieve意思是“对你所能达到的水平的限制”。

　　6、N

　　can genes also determine后面接了一系列的宾语从句，此处需填一个形容词，smart符合题意，表示“机灵，可爱”。

　　7、I

　　extent是先行词，后接定语从句，to the extent…意为“在……程度上”。

　　8、J

　　indicates，动词，后接宾语从句，意思是“表明，显示”。全句意为：越来越多的科学（现象）表明基因对人类很多特征起到了基础作用。

　　9、G

　　essentially，这类是个比喻句，exxentially的意思是“实际上，本质上”。全句意为：从这个角度来讲，人一出生，本质上就像是还没洗出来的照片：相已经照了，但是最终会呈现多少就在于显影的过程了。

　　10、H

　　此处填副词，由上一小题的分析可得知答案。Eventually副词，意思是“最终，最后”。
