Question

6．It is easy for us to tell our friends from our enemies．But can'other animals do the same？Elephants can!They can use their eyes'．a(chǎn)nd noses to tell the difference between dangerous people and friendly people In Kenya，scientists found that elephants knew the different clothes of Maasai and Kamba people Maasai men often kill animals S'or food，so they are dangerous to elephants．Kamba men are farmers and not a danger to elephantsLast year，some animal scientists did an experiment．They found that elephants reacted（反應(yīng)） differently to smell and color
       First，elephants were shown clothes of either a Maasai or a Kamba man．When the elephants smelt the clothes worn by a Maasai man，they moved away fast．When they smelt the clothes worn by Kamba men，they relaxed．
Then，the same elephants were shown red clothes．They got angry，because red is often worn by Maasai men．Instead of running away，the elephants rushed angrily to the red clothes．Why？If an elephant smells a danger，he thinks that the danger is close and the best thing to do is to run away and hide．If he sees a danger，he thinks the risk（危險(xiǎn)性） is low．So the elephant seems a little braver and ready to fight

Answer 1

分析 我們分辨敵友很容易，但是動(dòng)物也能這樣嗎？大象可以用視覺和嗅覺來判斷它們的敵人，在肯尼亞，大象能區(qū)分坎巴人與馬賽人的衣服，馬賽人常常為了食物殺動(dòng)物，所以他們對(duì)于大象是危險(xiǎn)的．坎巴人是農(nóng)民，沒有危險(xiǎn)性，試驗(yàn)后得知大象對(duì)味道和顏色反應(yīng)不同．
當(dāng)大象聞到一件馬賽人穿的衣服，他們很快就跑開了，當(dāng)聞到坎巴人穿的衣服，他們很放松．
大象看見紅色衣服就很生氣，因?yàn)轳R賽人喜歡穿紅色的．大象生氣的跑向紅色衣服，為什么？如果大象聞到了危險(xiǎn)，他認(rèn)為最好的方法是跑或者藏起來．如果看見了危險(xiǎn)，他認(rèn)為危險(xiǎn)性低，大象就會(huì)有一點(diǎn)勇敢，準(zhǔn)備去戰(zhàn)斗．

解答 46．答案：B．推理判斷題．根據(jù)第一段Elephants can!They can use their eyes'．a(chǎn)nd noses to tell the difference between dangerous people and friendly people 可知大象可以用視覺和嗅覺來判斷它們的敵人，可知大象是聰明的，故選B．
47．答案：B．細(xì)節(jié)理解題．根據(jù)第一段Kamba men are farmers and not a danger to elephants可知坎巴人是農(nóng)民，不殺動(dòng)物，故選B．
48．答案：C．推理判斷題．根據(jù)最后一段he thinks that the danger is close and the best thing to do is to run away and hide．If he sees a danger，he thinks the risk（危險(xiǎn)性） is low．So the elephant seems a little braver and ready to fight可知大象遇見了危險(xiǎn)會(huì)躲起來或者藏起來，或者沖過去戰(zhàn)斗，故選C．
49．答案：B．細(xì)節(jié)理解題．根據(jù)最后一段If an elephant smells a danger，he thinks that the danger is close and the best thing to do is to run away and hide．If he sees a danger，he thinks the risk（危險(xiǎn)性） is low．So the elephant seems a little braver and ready to fight可知大象認(rèn)為聞見的危險(xiǎn)是最大的，故選擇B．
50．答案：D．文章出處題．本文是說動(dòng)物也有自己的方法判斷敵我．文章講述了大象通過視覺和嗅覺來判斷它們的敵人．故可知這篇文章是出現(xiàn)在自然雜志上，故選D．

點(diǎn)評(píng) 所謂主旨大意題，就是指那些針對(duì)文章的主要內(nèi)容、主題、標(biāo)題或?qū)懽髂康乃�設(shè)置的問題．這類題主要考查同學(xué)們?cè)诶斫馊�文的基礎(chǔ)上運(yùn)用概括、判斷、歸納、推理等邏輯思維方法對(duì)文章進(jìn)行高度概括或總結(jié)的能力．
