up,students will first be guided to talk and share.Then they will be helped to read an exposition（说明文）entitled HOW LIFE BEGAN ON THE EARTH.Then the students may be asked to listen and read aloud，read and underline，read and understand difficult sentences，read and transfer information，read and translate,read to decide on the type of writing and summary of the text and finally read to draw a tree diagram of the text and retell the story with the help of the diagram.The period will end in students having a discussionHow Did the Uni verse Begin?Objectives To help students understand the text s

dissolve，exist，puzzle，crash，pull，float，exhaust Expressions in time,lay eggs,give birth to,block out,cheer up,now that,break out,watch out Patterns 1.It exploded loudly with fire and rock,which were in time to produce the water vapor,carbon dioxide,oxygen,nitrogen and other gases,which were to make the earth s atmosphere.2.Nobody knew that it was going to be different from other planets going round the sun.3.It allowed the earth to dissolve harmful gases,which had become part of the earth s atmosphere,into the oceans and seas.4.This encouraged the development of early shellfish and all sorts of fish.5.They produced young generally by laying eggs.6.They are putting too much carbon dioxide into the atmosphere,whichprevents heat from escaping from the earth into space.7.Whether life will continue on the earth for millions of years to come will depend on whether this problem can be solved.Aids Multimedia facilities,tape-recorder,photos,diagrams Procedures I.Warming up by learning vocabularyGood morning,class!Today,we are going to take Unit 4 Astronomy:the science of the stars.Before we read the text,let s turn to page 99 and get familiarized with the vocabulary first.Pay attention to the making of the word.Study the prefixes,roots and suffixes in the words.II.Pre-reading 1.Looking and sayingHave you ever wondere d how the universe began?Well Im sure you may have many

exciting.科学家透露：宇宙可能有两个我们的宇宙和一个隐藏的 宇宙共同 镶嵌 在五维空间 中。在我们的宇宙早期，这两个宇宙发生了一次相撞事故，相撞产生的能量生成了我们宇宙中的物质和能量。2.T alking and sharing Do you know how the universe began?I n the 1920s in California,astronomer Edwin Hubble observed distant galaxies using an extremely powerful telescope.He made two mind-boggling(unbelievable)discoveries.First,Hubble figured out that the Milky Way isn t the only galaxy.He realized that faint,cloud-like objects in the night sky are actually other galaxies far,far away.The Milky Way is just one of billions of galaxies.Second,Hubble discovered that the g alaxies are constantly moving away from each other.In other words,the universe is expanding.The biggest thing that we know about is getting bigger all the time.A few years later,Belgian astronomer Georges Lema?tre used Hubble s amazing discoveries to suggest an answer to a big astronomy question:“How did the universe begin?”3Listening and reading aloudNow please listen to the recording and then read the text aloud.Pay attention to how the native speaker is reading along and where the pauses are within each sentence.I will play the tape twice and you shall read aloud twice,too.4 Reading and underlining Next you are to read and underline all the useful expressions or collocations in the passage.Copy them into your notebook after class as homework.文档编码:CV9S7T10B5D1 HH5N10G5M1R6

after the“Big Bang”?A cloud of energetic dust at first and then a ball around the sun.In time as a result of its explosion,water vapor and many other gases were produced to make the earth s atmosphere.Water then appeared when it cooled down,offering the possibility for the beginning of life.Why was the earth different?The arrival of small plants growing in the water filled the oceans and seas with oxygen,encouraging the development of small living things.How was life developed on earth?Carbon dioxide and air with oxygen helped life developed.First were insects and amphibians,and then appeared reptiles and dinosaurs,producing young by laying eggs.At first,came mammals producing young from within their bodies.What did small clever animals do?With hands and feet,they spread all over the earth,developing new methods of growing food,hunting and moving around,yet neglecting the environment protection,causing new problems for human beings existence for good.5.Reading the text once

came growing in the water,followed by green plants appearing on land.In the end appeared small clever animals.Topic sentence of 1st paragraph After the“Big Bang”,the earth was just a cloud of energetic dust.Topic sentence of 2nd paragraph The earth was different because of the arrival of small plants growing in the water.Topic sentence of 3rd paragraph Many millions of years later the first green plants began to appear on land.Topic sentence of 4th paragraph Small clever animals appeared and spread all over the earth.文档编码:CV9S7T10B5D1 HH5N10G5M1R6 ZE1X4P10K7X2文档编码:CV9S7T10B5D1
