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(鳗鱼) 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 (个别的) 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 海豚是我们的朋友,虽然它们没有手,它们能用工具去解决问题,例如,科学家已经发现一只海豚能用一条死鱼让一条害羞的鳗鱼从它的洞里出来.
海豚用不同的声音交换彼此的信息.夏威夷科学家发明了一种信号语言给海豚指令,结果很惊人.他们发现海豚不仅仅理解个别词的含义,还理解句中那个重要的单词指令.
大多数动物喜欢玩,但是海豚似乎喜欢尽可能的带有挑战性地去做游戏.1997年的一个美好的一天,在海边的科学家刚看到一个小狗走进海里跟着海豚游泳.令她惊奇的是,海豚来到狗身边,开始将他丢到空中.狗很喜欢这个游戏,和海豚玩了一个多小时.
海豚住在和我们不同的世界,但是他们非常擅长我们的智商测试,例如,当它们听到口哨声它们会跳出水面.他们这样做因为他们会得到一条鱼作为奖励.
仍然还有很多要向这些可爱的麻烦解决者们学习的地方,但是看海豚表演很有趣是毫无疑问的.
解答 46.答案:C.细节理解题.根据第一段scientists have ever found that a dolphin can make a shy eel(鳗鱼) come out of its hole with a dead fish.可知海豚是用一只死鱼让鳗鱼出来,故选C.
