Peter writes music.He likes sounds and uses natural sounds as part of his music.He often went out to the wild with his microphone and recorded interesting sounds to put in movies or to use in his own songs.Instead of trying to capture just the sound of one animal or bird,he recorded the sound of everything all together-the animals,the trees,the wind and the earth.He called these recordings "soundscapes"-the sound of a certain place.Every soundscape Peter recorded had a lot of information. Back in his workshop,Peter used a computer to make a picture of all the sounds going on in a place.Each animal,bird and insect had its own place on the picture-its own notes in the music.The busier the picture,the richer the life in that place."While a picture may be worth 1,000 words,a soundscape is worth 1,000 pictures,"Peter said."Our ears tell us the sound of every leaf and animal and speak to the natural sources (来源)of our lives,which may hold the secrets of love for all things,especially our own humanity.” But not everything is satisfying.When Peter began recording over forty years ago,he could record for ten hours and get one hour of usable material good enough for a movie. Now,because of human activities,it can take up to 1,000 hours or more to get the same thing.Some of the places he has recorded over the years have slowly fallen silent.His sound pictures show that although nature might look the same to humans,it has lost part of its orchestra(管弦乐队). So next time you are in the forests,try another way to look-shut your eyes,and listen. 1.Why did Peter record natural sounds? A.To write songs for a music group. B.To discover rich lives in the forest. C.To use some of them in his music. D.To make music about birds singing. 2.新考向词义猜测What does the underlined word“capture'”in Paragraph2mean? A.Shut. B.Catch. C.Touch. D.Check. 3.What is a sound picture in the text? A.The sound of every leaf and animal in nature. B.The sound recorded in the natural environment. C.A picture of music with sounds of 1,000 animals. D.A picture of music with natural sounds in a place. 4.What can we learn from Paragraph 4? A.Recording sounds needs less material. B.Sound pictures are the same as before. C.Some beautiful sounds in nature are lost. D.Human activities improve recording results. 5.What does the writer mainly want to tell us? A.Nature is the source of our future. B.Nature has wonders to be heard. C.Making music enriches our lives. D.Making music needs information. 1-5 下册Unit4知，为避免冲突，需友好地进行交流，以寻找到使 双方都满意的方法。 二、1.anyone2.help3.scared4.teenagers5.if 6.connected 7.to deal 8.feel 9.our 10.many 11.remember 三、1-5 FABEC Unit 4 第1课时Section A(1a-2d) 基础达标训练 -1.surface 2.below 3.unusual 4.diving 5.wonders 二、1-5 ACDBC 能力拓展提升 、 1.A【解析】根据“Qomolangma,at8,848.86 meters,is the highest mountain in the world”可知，作者是通过 陈述一个事实来开启全文的。 2.C【解析】通读第一段可知，该段主要介绍了珠穆 朗玛峰是怎样形成的。 3.B【解析】通读全文可知，文章第一段介绍了珠穆 朗玛峰的形成；第二段介绍了其增长的速度；第三 段介绍了其增长的原因；最后一段总结全文，介绍 珠穆朗玛峰并不是唯一增长的山峰，并感叹大自然 的神奇。故文章为分一总结构。 4.B【解析】通读全文可知，本文主要围绕着珠穆朗 玛峰的增长而写。 二、1-5 ACFBG 第2课时Section A(3a-4d) 基础达标训练 -,1.civilizations 2.delicious 3.cities 4.wonderful 5.costs 二、1.miles2.development3.waterfalls 4.desert 5.pool 能力拓展提升 一、 1.B【解析】此处指这儿有一些不同的方法去确定哪 个是世界上最大的湖。 2.C【解析】由前文的“the largest lake”可知，此处指 最多的水。 3.A【解析】由后文的“saltwater lakes'”和“others”可 推知，这里表示比较。 4.B【解析】根据下面的内容可知，此处表示的是咸 水湖和其他湖之间的区别。 5.C【解析】根据下文说可以从不同的方面来讨论可 知，这不是一个简单的问题。 6.C【解析】前文与后文是因果关系，因此用s0来 连接。 7.A【解析】根据下文中的“freshwater”可知，贝加尔 湖是淡水湖。 8.D【解析】这里指的是上文中提到的贝加尔湖，是 单数的事物，因此用t来指代。 9.B【解析】由上文提到的湖水的体积可知，此处指 数字。 10.B【解析】根据后文的“square kilometers'”可知， 这里表示的是面积。 11.C【解析】此处指苏必利尔湖在美国与加拿大之 间，因此用介词between来连接。 12.A【解析】句意：世界上也有一些其他有趣的湖。 13.D【解析】根据句意可知，这里表示如果你想了解 这些湖。 14.B【解析】此处指网站包括许多关于不同湖的有 趣的真相。 15.D【解析】根据句意及常理推断，这里表示的是 “我”相信你们（浏览网站时）会开心。 二、1-5 CBEDF 写作小练笔 Lushan Waterfall is a famous natural wonder in Jiangxi,China.The water falls from very high mountains,looking like a white dragon flying down.
