Unit 1 Friendship一、阅读理解。Spider(蜘蛛) webs have something in mon 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 webmaybe a possible mate，or something tasty to eat.Vibrations are not just used to spot what is for dinner. They are also important in courtship(求爱), so lots of males will actually create a very specific kind of musical pattern which the females can use to determine not only that theyre a male, but theyre the right species, and whether they might want to mate with them as well.Spiders make their own vibrations to find out the condition of the webs. By controlling the tightness of the material, they can effectively control how information is getting to them when they hang out in the middle of the web.Spiders have a special ability to shape the physical nature of their selfmade materials and creations. Scientists think that spider silk may have changed over time for this purpose.【解题导语】本文介绍了蜘蛛吐出的蛛丝可以传播不同频率的振动，这些振动让它们知道蜘蛛网上落下了什么东西并且这些振动在求爱中也非常重要。1How does a spider feel that an insect is caught in the web?AThrough its sense of sight.BThrough vibrations of its web.CThrough different frequencies.DThrough a musical pattern.B解析：细节理解题。根据第二段的“The vibrations can give the spider details about what is caught in the web”可知，蜘蛛可以通过蛛网的振动知道有东西落到蛛网上了。故选B项。2What does the underlined word “They” in Paragraph 2 probably refer to?AInsects.

concerned about . “担忧，挂念”，本句中逗号后没有连词，故逗号后的部分为状语，此处应用形容词短语作伴随状语。3Its no pleasure _ (go) camping on such a foggy day.答案：goingIts no pleasure doing sth. “做某事没有乐趣”。4The little boy is clever enough to have
