Question

16．Rob Coulter worked in the wild of South Africa．He knew the animals，insects，and reptiles（爬行動(dòng)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 文章講述了一個(gè)喜歡在野外旅行的人不小心被蛇咬到了然后想辦法自救的事，是一篇關(guān)于旅行的文章．

解答 41．A   推斷題．文章講述了一個(gè)喜歡在野外旅行的人不小心被蛇咬到了然后想辦法自救的事，是一篇關(guān)于旅行的文章，故這個(gè)文章可能出現(xiàn)在旅行雜志上，故正確答案為A．
42．D   細(xì)節(jié)題．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，當(dāng)他看到胳膊上的牙印時(shí)，他意識(shí)到自己被毒蛇咬了，故正確答案為D．
43．A    細(xì)節(jié)題．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，被蛇咬后要保持鎮(zhèn)定而且不要?jiǎng)�，所以A項(xiàng)正確．B項(xiàng)，被蛇咬后要保持不要?jiǎng)�，所以B項(xiàng)錯(cuò)誤．C項(xiàng)，由第四段第二句"avoid eating or drinking anything，especially anything with alcohol in it"可知，被蛇咬后不能喝帶有酒精的東西，所以C項(xiàng)錯(cuò)誤．D項(xiàng)，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，切掉中毒的肢體不是個(gè)好主意，所以D項(xiàng)錯(cuò)誤．故正確答案為A．
44．B   推斷題．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 一命的東西，所以應(yīng)該為抵抗毒素的藥物，故正確答案為B．

點(diǎn)評(píng) 1、要想做好科普英語(yǔ)閱讀理解題，同學(xué)們就要注意平時(shí)多讀科普知識(shí)類文章，學(xué)習(xí)科普知識(shí)，積累常見的科普詞匯，從根本上提高科普英語(yǔ)的閱讀能力．
2、要熟悉科普類文章的結(jié)構(gòu)特點(diǎn)．科普類文章一般由標(biāo)題（Head line），導(dǎo)語(yǔ)（Introduction），背景（Back ground），主體（Main body）和結(jié)尾（End）五部分構(gòu)成．標(biāo)題是文章中心思想高度而又精辟的概括，但根據(jù)歷年的高考情況來(lái)看，這類閱讀理解材料一般不給標(biāo)題，而要同學(xué)們選擇標(biāo)題．導(dǎo)語(yǔ)一般位于整篇文章的首段．背景交待一個(gè)事實(shí)的起因．主體則對(duì)導(dǎo)語(yǔ)概括的事實(shí)進(jìn)行詳細(xì)敘述，這一部分命題往往最多，因此，閱讀時(shí)，同學(xué)們要把這部分作為重點(diǎn)．結(jié)尾往往也是中心思想的概括，并與導(dǎo)語(yǔ)相呼應(yīng)，命題者常在此要設(shè)計(jì)一道推理判斷題．　　
3、在進(jìn)行推理判斷時(shí)，同學(xué)們一定要以閱讀材料所提供的科學(xué)事實(shí)為依據(jù)，同時(shí)所得出的結(jié)論還應(yīng)符合基本的科普常識(shí)．
