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

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".可知海豚擅長智力測試,結(jié)合本文是說海豚懂得人們給出的指令,可知海豚是聰明的,故選B.
點評 海豚是我們?nèi)祟惖倪便宜,學(xué)生很了解,故文章理解起來要容易多了,都是細節(jié)理解題,能從文中找到答案,但一定要忠于原文.
