Unit 2 Cloning

李仕才

***阅读理解。

Spider(蜘蛛) webs have something in common with guitar strings.

The long, thin strings on a guitar can vibrate(振动). They move back and

forth, or from side to side. So do webs made by spiders. The lines of silk

they produce can carry vibrations. This movement gives the small

creature information about what landed on the web.

Spiders have eight legs and usually eight eyes. The animals build

webs with their own soft, naturally­made silk. And much like playing the

strings of a guitar, a spider can send out vibrations across its web

over many different frequencies(频率). Spiders catch their food,

usually insects in their webs. They make small movements, which spread

across their webs. The vibrations can give the spider details about what

is caught in the web—maybe a possible mate,or something tasty to
