13.Dolphins are our friends.They can use tools to solve problems although they don't have hands.For example,scientists have ever found that a dolphin can make a shy eel(鰻魚(yú)) come out of its hole with a dead fish.
Dolphins use different sounds to exchange information with each other.Scientists in Hawaii have developed a sign language to give instructions to dolphins,and the results are amazing.They find that dolphins not only understand the meaning of individual (個(gè)別的) words,but also understand the importance of word order in a sentence.
Most animals enjoy playing-but dolphins seem to like making their games as challenging as possible.On a beautiful day in 1997,scientists at a beach watched a little dog going into the sea and swimming towards the dolphins.To their surprise,the dolphins came up to the dog and then started throwing it into the air.The dog seemed to enjoy the"game"and continued playing with the dolphins for more than an hour.
Dolphins live in a very different world from ours,but they are very good at our"IQ tests".For example,they will jump out of the water when they hear a whistle (口哨) noise.They do this because they will get a fish as a prize.
There is still much to learn about these cute problem-solvers,but it is certain that watching a dolphin show is fun.

分析 海豚是我們的朋友,雖然它們沒(méi)有手,它們能用工具去解決問(wèn)題,例如,科學(xué)家已經(jīng)發(fā)現(xiàn)一只海豚能用一條死魚(yú)讓一條害羞的鰻魚(yú)從它的洞里出來(lái).
海豚用不同的聲音交換彼此的信息.夏威夷科學(xué)家發(fā)明了一種信號(hào)語(yǔ)言給海豚指令,結(jié)果很驚人.他們發(fā)現(xiàn)海豚不僅僅理解個(gè)別詞的含義,還理解句中那個(gè)重要的單詞指令.
大多數(shù)動(dòng)物喜歡玩,但是海豚似乎喜歡盡可能的帶有挑戰(zhàn)性地去做游戲.1997年的一個(gè)美好的一天,在海邊的科學(xué)家剛看到一個(gè)小狗走進(jìn)海里跟著海豚游泳.令她驚奇的是,海豚來(lái)到狗身邊,開(kāi)始將他丟到空中.狗很喜歡這個(gè)游戲,和海豚玩了一個(gè)多小時(shí).
海豚住在和我們不同的世界,但是他們非常擅長(zhǎng)我們的智商測(cè)試,例如,當(dāng)它們聽(tīng)到口哨聲它們會(huì)跳出水面.他們這樣做因?yàn)樗麄儠?huì)得到一條魚(yú)作為獎(jiǎng)勵(lì).
仍然還有很多要向這些可愛(ài)的麻煩解決者們學(xué)習(xí)的地方,但是看海豚表演很有趣是毫無(wú)疑問(wèn)的.

解答 46.答案:C.細(xì)節(jié)理解題.根據(jù)第一段scientists have ever found that a dolphin can make a shy eel(鰻魚(yú)) come out of its hole with a dead fish.可知海豚是用一只死魚(yú)讓鰻魚(yú)出來(lái),故選C.
47.答案:D.細(xì)節(jié)理解題.根據(jù)第二段Dolphins use different sounds to exchange information with each other可知是用不同的聲音交換信息,故選D.
48.答案:B.細(xì)節(jié)理解題.根據(jù)第三段To their surprise,the dolphins came up to the dog and then started throwing it into the air可知是將狗扔向空中,故選B.
49.答案:A.細(xì)節(jié)理解題.根據(jù)第四段they will jump out of the water when they hear a whistle (口哨) noise.They do this because they will get a fish as a prize.可知是想獲得獎(jiǎng)勵(lì),故選A.
50.答案:B.推理判斷題.根據(jù)第四段Dolphins live in a very different world from ours,but they are very good at our"IQ tests".可知海豚擅長(zhǎng)智力測(cè)試,結(jié)合本文是說(shuō)海豚懂得人們給出的指令,可知海豚是聰明的,故選B.

點(diǎn)評(píng) 海豚是我們?nèi)祟惖倪便宜,學(xué)生很了解,故文章理解起來(lái)要容易多了,都是細(xì)節(jié)理解題,能從文中找到答案,但一定要忠于原文.
