Question

16．Rob Coulter worked in the wild of South Africa．He knew the animals，insects，and reptiles（爬行动物）of Africa very well．Rob knew them so well that he became careless．
One night，while camping alone，Rob reached out to pick up a large piece of wood and felt something bite his arm．Rob didn't think much about it．But a little later，his arm began to ache．When he looked closely at it，he immediately saw two teeth marks in the skin of his arm．He realized that a poisonous snake had bitten him．His pulse became rapid．
Rob's mind raced as he thought about what he had to do to survive．Rob knew that he should remain calm，stay still，keep the injured arm below the level of his heart and avoid eating or drinking anything，especially anything with alcohol in it．He also knew that cutting the wound to suck the poison out was a bad idea．
He used his two-way radio to call for help．As he waited，he washed the bite with soap and water．To help slow the spread of the venom（毒液），he wrapped a bandage two inches above the bite and made it loose enough to slip a finger under it so that it would not cut off the flow of blood．Then，after about half an hour，his friend Mike arrived．Mike took Rob to the local hospital，where Rob was given antivenin-an antidotefor snake venom．
Rob still enjoys camping，but he is now very careful not to disturb snakes．

Answer 1

分析 文章讲述了一个喜欢在野外旅行的人不小心被蛇咬到了然后想办法自救的事，是一篇关于旅行的文章．

解答 41．A   推断题．文章讲述了一个喜欢在野外旅行的人不小心被蛇咬到了然后想办法自救的事，是一篇关于旅行的文章，故这个文章可能出现在旅行杂志上，故正确答案为A．
42．D   细节题．由第三段"When he looked closely at it，he immediately saw two teeth marks in the skin of his arm．He realized that a poisonous snake had bitten him．His pulse became rapid"可知，当他看到胳膊上的牙印时，他意识到自己被毒蛇咬了，故正确答案为D．
43．A    细节题．由第四段第二句"Rob knew that he should remain calm，stay still，keep the injured arm below the level of his heart"可知，被蛇咬后要保持镇定而且不要动，所以A项正确．B项，被蛇咬后要保持不要动，所以B项错误．C项，由第四段第二句"avoid eating or drinking anything，especially anything with alcohol in it"可知，被蛇咬后不能喝带有酒精的东西，所以C项错误．D项，由第四段最后一句"He also knew that cutting the wound to suck the poison out was a bad idea"可知，切掉中毒的肢体不是个好主意，所以D项错误．故正确答案为A．
44．B   推断题．由第五段最后一句"Mike took Rob to the local hospital，where Rob was given antivenin-an antidote for snake venom"可知，antidote 是救了 Rob Coulter 一命的东西，所以应该为抵抗毒素的药物，故正确答案为B．

点评 1、要想做好科普英语阅读理解题，同学们就要注意平时多读科普知识类文章，学习科普知识，积累常见的科普词汇，从根本上提高科普英语的阅读能力．
2、要熟悉科普类文章的结构特点．科普类文章一般由标题（Head line），导语（Introduction），背景（Back ground），主体（Main body）和结尾（End）五部分构成．标题是文章中心思想高度而又精辟的概括，但根据历年的高考情况来看，这类阅读理解材料一般不给标题，而要同学们选择标题．导语一般位于整篇文章的首段．背景交待一个事实的起因．主体则对导语概括的事实进行详细叙述，这一部分命题往往最多，因此，阅读时，同学们要把这部分作为重点．结尾往往也是中心思想的概括，并与导语相呼应，命题者常在此要设计一道推理判断题．　　
3、在进行推理判断时，同学们一定要以阅读材料所提供的科学事实为依据，同时所得出的结论还应符合基本的科普常识．
