总结

　Not all sounds made by animals serve as language, and we have only to turn to that extraordinary discovery of echo-location in bats to see a case in which the voice plays a strictly utilitarian role.

Not all sounds made by animals serve as language, and we have only .... 非常好的引入方式，其实是把一个事物的上意词和下衣词做对比。

To get a full appreciation of what this means we must turn first to some recent human inventions.

to get a full appreciation of what this means we must turn first to sth

巧妙的转折，这里从一个类比物的角度来引入具体的实际的好处

So was born the echo-sounding apparatus, now in general use in ships.

倒装句，不是说句子特别长才复杂，才生动，这个短句的倒装就特别好，醒目的表达了echo-sounding apparatus诞生的过程

Every solid object will reflect a sound, varying according to the size and nature of the object.
Every solid object will reflect a sound, varying according to the size and nature of the object. A shoal of fish will do this.
So it is a comparatively simple step from locating the sea bottom to locating a shoal of fish. With experience, and with improved apparatus, it is now possible not only to locate a shoal but to tell if it is herring, cod, or other well-known fish, by the pattern of its echo. 这个句子学习下，是怎么把长长的一段话写得特别好！没有生拉硬扯的感觉。

Not all sounds made by animals serve as language, and we have only to turn to that extraordinary discovery of echo-location in bats to see a case in which the voice plays a strictly utilitarian role. To get a full appreciation of what this means we must turn first to some recent human inventions. Everyone knows that if he shouts in the vicinity of a wall or a mountainside, an echo will come back. The further off this solid obstruction, the longer time will elapse for the return of the echo. A sound made by tapping on the hull of a ship will be reflected from the sea bottom, and by measuring the time interval between the taps and the receipt of the echoes, the depth of the sea at that point can be calculated. So was born the echo-sounding apparatus, now in general use in ships. Every solid object will reflect a sound, varying according to the size and nature of the object. A shoal of fish will do this. So it is a comparatively simple step from locating the sea bottom to locating a shoal of fish. With experience, and with improved apparatus, it is now possible not only to locate a shoal but to tell if it is herring, cod, or other well-known fish, by the pattern of its echo. It has been found that certain bats emit squeaks and by receiving the echoes, they can locate and steer clear of obstacles -- or locate flying insects on which they feed. This echo-location in bats is often compared with radar, the principle of which is similar.</div>
