15.How Animals Hear. 动物如何听到声音 　　1. When we talk about ears, we usually mean the oddly[(odd).奇怪的] wrinkled[adj.有皱纹的] appendages[(appendage):n.附加物] on the sides of our heads. 1、当我们提到耳朵，通常指那个生长在我们头部两侧的奇怪的褶皱的附属肢体。 分析：talk about=谈论；oddly=奇怪地；wrinkled =褶皱的；appendages=附加物； 2. We are aware[a.知道的,意识到的] that at the end of the central[adj.中心的，中央的] hole in this outer ear there is something called the middle ear, with an eardrum[n.耳膜] and a few little bones[(bone):n.骨，骨头]. Even deeper lies the inner ear, the organ[n.器官] with which we hear. 2、我们知道，在外耳中孔的底部有东西称为中耳，它由一个耳鼓和一些小骨骼构成。而真正能使我们“听”的器官在更深处的内耳。 分析：at the end of＝在….末端；aware ＝知道的； central=中央的； eardrum=耳鼓，ear耳，drum鼓；a few＝少数； bone＝骨头； organ=器官 3. Animals such as dogs and cats also have conspicuous[adj.明显的] outer ears, but few of us probably[adv.很可能；大概] ever stopped to think whether there might[v.aux.可能；也许] be such a thing as a middle and inner ear beneath[prep.在…下面] those pointed tips[(tip):n.尖端]. Yet, we know very well that these animals hear. 3、诸如猫和狗这样的动物也有引人注目的外耳，但很少人能够停下来去想，在竖立的尖儿下面，是否那里也有类似于中耳和内耳的东西。但是我们很清楚地知道这些动物都能够听到。 分析：beneath在…下面（被别的东西覆盖），under 在垂直的…下面 below在…下面； stop to do停下来去做某事， stop doing停止做某事； 单词：conspicuous＝的； whether ＝是否； such…as…＝像…..这样beneath＝在…之下； pointed＝； tip＝尖； 4. Birds are even more mysterious[adj.神秘的;难以理解的], because here we do not even see an outer ear. The same is true to still a larger degree[n.度；度数；学位] of such animals as frogs[(frog):n.蛙] and fishes, although[conj.尽管，虽然] in the frog[n.蛙] we can at least[n.最少量；最少] see an eardrum[n.耳膜]. 4、鸟类甚至更为神秘，因为我们甚至看不到它们有一个外耳。还有很大数量的动物如青蛙和鱼类也是如此，虽然我们至少可以看到青蛙有一个耳鼓。 分析：at least＝至少；mysterious＝神秘； degree＝程度； frogs＝青蛙；fishes＝鱼类, eardrum＝耳鼓 5. Again, at one time or another, you may have found that all such animals hear. Hunters[(hunter):n.搜寻者] know that birds are attracted[(attract):vt.吸引；引起] by artificial[adj.假的,人工的] calls, and fishermen[n.渔夫,钓鱼者,渔船] emphasize[v.强调] that you should be as quiet as possible if you dont want to go home empty handed. And if you
