Question

Pigs are always considered dirty animals because they roll in mud．But in fact they prefer  being quite clean．They cover themselves with mud to help stay cool．During cooler weather,  they prefer to stay clean．So do elephants, who also cover themselves in dust or mud to keep cool．When they find a place with clean water they will take a bath，using their long noses to give  themselves—or each other—a nice shower
Some animals use dust to get clean．Chinchillas (南美洲栗鼠) have very fine fur． They don’t like to take water baths because water is not warm enough for them．So, instead, they roll  around in fine dust．The dust helps to keep their fur and skin dry．This protects them from disease
Usually, a small bird is a light meal for a crocodile．But when a crocodile wants its teeth  cleaned．it lies on the ground with its mouth open．The crocodile bird goes in and picks out any  parasites(寄生蟲)between the crocodile’s teeth or under its tongue．The crocodile gets its mouth cleaned，and the crocodile bird gets dinner．
You wouldn’t think fish would need baths．But some undersea parasites live under the  fish’s skin．“Cleaner” fish，like the wrasse(隆頭魚)，help take them away．The wrasse stands on its head and dances to signal a big fish that it is ready to go into the cleaning business．The big fish will stop moving and open its mouth wide so the wrasse can swim inside and pick out  parasites and bits of food．

試題分析：本文主要講述的是很多動(dòng)物也很喜歡干凈，不過(guò)不同的動(dòng)物保持清潔的方式是不一樣的。
1.A 主旨大意題。本文主要講述了不同的動(dòng)物保持清潔的不同的方法，有的動(dòng)物使用泥漿，有的短文使用其它的動(dòng)物，如鱷魚等。故A正確。
2.D 細(xì)節(jié)題。根據(jù)第一段2,3行They cover themselves with mud to help stay cool．During cooler weather,  they prefer to stay clean．說(shuō)明豬也喜歡干凈，故D正確。
3.B 細(xì)節(jié)題。根據(jù)文章第二段Some animals use dust to get clean．Chinchillas (南美洲栗鼠) have very fine fur． They don’t like to take water baths because water is not warm enough for them．So, instead, they roll  around in fine dust．The dust helps to keep their fur and skin dry．This protects them from disease可知ACD都是他們使用灰塵來(lái)保持清潔的原因，只有B項(xiàng)沒有提及。
4.A 段落大意題。在文章第三段里講述了鱷魚借The crocodile bird進(jìn)行口腔的清潔；一些大魚借the wrasse(隆頭魚)來(lái)保持清潔。故講述的是不同的動(dòng)物靠其它的動(dòng)物保持清潔的故事。故A正確。
5.C 推斷題。根據(jù)文章最后“Cleaner” fish，like the wrasse(隆頭魚)，help take them away．The wrasse stands on its head and dances to signal a big fish that it is ready to go into the cleaning business．The big fish will stop moving and open its mouth wide so the wrasse can swim inside and pick out  parasites and bits of food．可知這種魚可以進(jìn)入其它的魚的口腔，說(shuō)明他們的體型較小，故C正確。
考點(diǎn)：考查自然知識(shí)類短文閱讀
點(diǎn)評(píng)：本文講述的是不同的動(dòng)物保持清潔的不同方式。文章基本上是考查細(xì)節(jié)題，對(duì)此類題型考生可以首先從問題中找到關(guān)鍵詞，然后以此為線索，運(yùn)用略讀及查閱的技巧在文中迅速尋找這一細(xì)節(jié)，找到后再把這一部分內(nèi)容仔細(xì)閱讀一遍，仔細(xì)比較所給選項(xiàng)與文中細(xì)節(jié)的細(xì)微區(qū)別，在準(zhǔn)確理解細(xì)節(jié)的前提下，最后確定最佳答案。
