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(chóng))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(yú))，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．

【小題2】D
【小題3】B
【小題4】A
【小題5】C

解析試題分析：本文是一篇科普類(lèi)閱讀。文章列舉了大量的例子介紹了動(dòng)物們是如何保持潔凈的。如豬，南美洲栗鼠及鱷魚(yú)鳥(niǎo)，隆頭魚(yú)等。
【小題1】主旨大意題。整篇文章都介紹了動(dòng)物們是如何保持潔凈的。故選A。 　
【小題2】細(xì)節(jié)題。從第一段But in fact they prefer  being quite clean．They cover themselves with mud to help stay cool可知正確答案為D
【小題3】細(xì)節(jié)題。文章第二段對(duì)ACD均有描述，只有B答案表述不正確，故選B。
【小題4】推理判斷題。由第三段可知，鱷魚(yú)鳥(niǎo)會(huì)幫助鱷魚(yú)清理牙齒；由第四段可知隆頭魚(yú)會(huì)幫助其他魚(yú)類(lèi)清理寄生蟲(chóng)。兩段共同之處是：某些動(dòng)物可以依靠其他動(dòng)物的幫助保持干凈。B、C、D三項(xiàng)在文章第三、四段中找不到根據(jù)。
【小題5】推理判斷題。根據(jù)文章第四段最后一句可知，隆頭魚(yú)可以游入其他魚(yú)類(lèi)的口中，這說(shuō)明它是一種小魚(yú)。
考點(diǎn)：科普類(lèi)閱讀。
點(diǎn)評(píng)：文章介紹了動(dòng)物們是如何保持潔凈的。文中列舉了大量的例子來(lái)介紹動(dòng)物保持潔凈的方式，閱讀中要注意把握方式這一線索，多讀幾遍，然后帶著問(wèn)題通讀全文，找出答題依據(jù)，完成閱讀。
