To talk about endangered species2. To read about and understand wildlife protectionTeaching Procedures:Step 1. Warming UpPurpose: To activate Ss and arouse them to talk about endangered species.1.Leading-inThe title of this unit is wildlife protection and we all know that there are many endangered species in the world. Now class, which animals are in danger? Name as many wild animals as you can.2. IntroductionLook at the animals on page 25.We are very familiar with the giant panda，milu deer and south China tiger. The giant panda lives in mountainous regions, like Sichuan and Tibet. The giant panda is a symbol of the World Wildlife Fund, a conservation organization. Toward the latter half of the 20th century, the panda also became women what a national emblem for China, and is now used in Chinese gold coins. Milu deer has a long tail, wide hooves and branched antlers. Another Chinese name for it is "four unlikes" because the animals we seen as having the horns of a stag, the neck of a camel, the foot of a cow, and the tail of an ass. A tiger is a large cat famous for its beautiful fur of orange striped with black. Tigers lives in Asia and are becoming very rare.

The number of pandas, which nearly disappeared years ago, has now risen to about 70, the number of milu deer to about 500, and the number of South China tigers about 60.(3)Why should we protect wildlife?Suggested Answer:Wildlife is our friends. They can keep the balance of nature and make the whole world colorful. To protect wildlife is to protect ourselves.（4）What do you think we should do to protect wildlife?Suggested Answer: We should treat plants and ani mals the same as our friends and relatives.

As the sweaters become popular, more and more animals arekilled. So very few antelopes are left.②The farmers stopped killing the elephants, so the numbers increased.③The government helps the farmers. It makes sure that the tour companies pay the farmers whentourists come to visit and hunt a few animals.④Looking after the rainforest helps protect plants and animals we know nothing about. They may makeit possible for us to produce medicines and drugs that we don’t yet know about.⑤Students’ answers vary.(4) Further readingPurpose: To get Ss to get more details about the text.1. Read paragraph one and answer the question.Why are we humans part of this problem?Suggested Answer:People who buy sweaters made with Tibetan wool are encouraging more people to go out and kill the animals.2.

Suggested Answer:The farmers got money when the government made sure that the tour companies had to pay them to visit and hunt the animals. And the animals were no longer killed by the farmers for destroying the crops.)3. Read paragraph four, five and answer the questionIn what ways does looking after the rain forest help with wildlife protection?Suggested Answer:Looking after the rain forest helps wildlife protection because it is where wildlife lives.

The teacher summarize the text.One day, Daisy dreamed a strange dream. She flew in a wonderful chair to talk with an antelop in Tibet. The antelope told her they were hunted because of their fur, which can be used to make sweater like hers. In three years they may all be gone. Later, she flew to Zimbabwe where she talked with an elephant and got to know the farmers there no longer hunted them. That’s because the government decided to help and the farmers finally made a lot of money. At last she arrived at the thick rain forest where a monkey told her “No rain forest, no animals and no drugs.” Although finally everything was gone, she had learned so much.2. Homework(1)Let Ss listen to the tape and follow in a low voice.(2)Ask Ss to preview Learning about Language.Period 3 Learning about languageTeaching Goals: 1.To learn about The Present Progressive Passive voice2.

Grammar1. The introduction about the passive voice and the present progressive passive voiceThe passive voice is used when focusing on the person or thing affected by an action. The passive voice is formed: passive subject +to be + past participle. It is often used in business and in other areas where the object of the action is more important than those who perform the action. For example, We have produced over 20 different models in the past two years.→Over20 different models have been produced in the past two years.If the agent (the performer of the action) is important, use “by”.For example, Tim Wilson wrote The Flight To Brunswick in 1987.→The Flight To Brunswick was written in 1987 by Tim Wilson.Only verbs that take an object can be used in the passive.The present progressive passive voice is formed: is/are/am +being done.2. Let Ss find some sentences of the above kind in the text and do some exercises.Purpose: To make Ss further understand the structure of the sentence pattern.(1) Suggested sentencesOur fur is being used to make sweaters like yours.Daisy turned round and saw she was being watched by an excited elephant.(2) Exercise①The Tibetan antelope ____________(hunt)by people who wish to take the fur from under their stomachs.②The rhino __________________(study)Beijing University students.③The African elephant _________________(protect)by the WWF.④The panda ____________________(photograph)by Daisy.⑤The whales _________________ (kill)by Japanese fishermen.⑥The mice ___________________(attack)by the cat.Suggested Answers: ①is being hunted ②is being studied by ③is being protected ④is being photographed ⑤are being killed ⑥are being attacked.3. ConsolidationThe following chart includes sentences changed from the active voice to the passive voice. Ask Ss to read the chart carefully and ask if they have any questions.Active Passive Time ReferenceThey make Fords in Cologne Fords are made in Cologne. Present SimplePresent ContinuousSusan is cooking dinner Dinner is being cooked bySusan.Past SimpleJames Joy wrote Dubliners. Dubliners was written by JamesJoyces.They were painting the house when I arrived. The house was being painted when I arrived. Past Continuous They have produced over 20 models in the past two years. Over 20 models have been produced in the past two years.Present Perfect They are going to build a new factory in Portland. A new factory is being built in Portland. Future Intention with Going to I will finish it tomorrow.It will be finished tomorrow.Future SimpleStep 3. Passive Verb FormationPurpose: To make Ss further understand the passive forms of a verb in various tenses 1. IntroductionThe passive forms of a verb are created by combining a form of the “to be verb ” with the past participle of the main verb. Other helping verbs are also sometimes present: “The measure could have been killed in committee.” The passive can be used, also, in various tenses. 2. ConsolidationAsk Ss to take a look at the passive forms of “design ”.Tense SubjectAuxiliaryPast ParticipleSingular Plural designed. Present The car/cars is are designed. Present perfect The car/cars has been have been designed. Past The car/cars was were designed. Past perfect The car/cars had been had been designed. Future The car/cars will be will be designed.

To talk about helping the dodo. 3. To write to the dodo.Teaching ProceduresStep 1. Warming UpPurpose: To get a brief understanding of the text.To improve Ss’ listening ability.1. ListeningLet’s warm up by reading the text about dinosaurs on page 30 and find the main idea of the text.Suggested Answer:Main idea: The development of dinosaurs.2. Group workDivide Ss into 4 groups and ask each group to talk about what they know about dinosaurs.3. In formation about DinosaurDinosaur means terrible lizard in Latin. They were called that because people used to think dinosaurs were lizards, but the were not. Dinosaurs first appeared about 200 million years ago. 65 million years ago, many kinds of dinosaurs became extinc Birds are a special type of dinosaur and they were the only kind to live until today.There were many kinds of dinosaurs. Some ate plants and some ate meat. The largest dinosaurs were plant-eaters lik apatosaurus and brachiosaurus. They were the largest animals to ever walk on dry land.Other plant-eaters had special weapons to help them fight off the meat-eaters. For example, triceratops had three horns on i face, ankylosaurus was covered in boney plates, and stegosaurus had spikes on its tail.The meat-eaters all ran around on their back legs like people do. Some were very large, like tyrannosaurus, and some wesmall, like compsognathus. It was the smaller sized meat-eaters that evolved into birds. One of the first birds w archaeopteryx, but it looked half like a dinosaur.There were large flying reptiles that lived at the same time as dinosaurs called pterosaurs, but they were not closely related dinosaurs. There were also many kinds of large reptiles that could swim, like ichthyosaurs and pleisiosaurs, but they weren closely related to dinosaurs either.Step 2. ReadingPurpose: To increase students’ vocabulary and expressionsTo help Ss get a further understanding about the whole story.1. Read the questions in the table below and scan the text to answer them.When did dinosaurs live on earth?When did dinosaurs die out?How did dinosaurs die out?2.

The Dodo, which is now extinct, lives on fruitand nests on the ground.2. Ask Ss to listen to the tape and do Ex3 and Ex4on page 30.Ex3: No 2 is correct.No 1 is wrong. It is not fair to blame the dodo for his disappearance.No 3 only explain half the story. The dodo and man did become friends but only because man wanted to kill all the dodo as easily as possible.No 4 is wrong because the other animals and birds did not do much to save the dodo. They warned him but did not he him.Ex 4：Read the whole text silently and carefully and finish the following questions:(1)The dodo is _________.A. fierceB. unkindC. friendlyD. foolish(2)He wants to believe that Man is telling the truth because___________.A.

We found that thehabitat of polar bears is disappearing because the ice at the North Pole is getting warmer. I worry thatwhen it disappears altogether, there will be nowhere for the polar bears to live.First, I suggest we are very careful with the energy we use. Global warming happens because we areputting too much carbon dioxide into the air. One of the ways we do this is by driving everywhere by car.So I suggest we think carefully before using our cars unnecessarily.Second, instead of using our cars we should think about traveling by bus or by train. These forms oftransport are more environmentally friendly and do not put so much carbon dioxide into the atmosphere.Third, we can join WWF which is fighting to save the habitat of the polar bear. We can raise money tohelp them by making and selling cakes, selling crafts or giving talent shows and charging money for ourparents to watch.I hope you will support us in our fight to save the home of the Polar Bears.Yours sincerely,Wu XiaoxinStep 3.

必修 2 unit1IN SEARCH OF THE AMBER ROOMFrederick William Ⅰ， the King of Prussia , could never have imagined that his greatest gift to the Russian people would have such an amazing history . This gift was the Amber Room , which was given this name because severaltons of amber were used to make it . The amber which was selected had a beautiful yellow-brown colour like honey . The design of the room was in the fancy style popular in those days . It was also a treasure decorated with gold and jewels , which took the country's best artists about ten years to make .In fact , the room was not made to be a gift . It was designed for the palace of Frederick Ⅰ. However, the next King of Prussia , Frederick William Ⅰ ,to whom the amber room belonged, decided not to keep it. In 1716 he gave it to Peter the Great.In return , the Czar sent him a troop of his best soldiers. So the Amber Room because part of the Czar's winter palace in St Petersburg.About four metres long,the room served as a small reception hall for important visitors .Later,Catherine Ⅱ had the Amber Room moved to a palace outside St Petersburg where she spent her summers. She told her artists to add more details to it .In 1770 the room was completed the way she wanted . Almost six hundred candles lit the room ,and its mirrors and pictures shone like gold. Sadly , although the Amber Room was considered one of the wonders of the world , it is now missing .In September 1941, the Nazi army was near St Petersburg . This was a time when the two countries were at war . Before the Nazis could get to the summer palace ,the Russians were able to remove some furniture and small art objects from the Amber Room . However , some of the Nazis secretly stole the room itself . In less than two days 100,000 pieces were put inside twenty-seven wooodenboxs . There is no doubt that the boxs were then put on a train for Konigsberg, which was at thattime a German city on the Baltic Sea . After that, what happened to the Amber Room remains a mystery .Recently , the Russians and Germans have built a new Amber Room at the summer palace . By studying old photos of the former Amber Room , they have made the new one look like the old one .In 2003 it was ready for the people of St Petersburg when they celebrated the 300th birthday of their city .A FACT OR AN OPINION?What is a fact? Is it something that people believe? No. A fact is anything that canbe proved. For example, it can be proved that China has more people than any othercountry in the world. This is a fact.Then what is an opinion? An opinion is what someone believes is true but has notbeen proved. So an opinion is not good evidence in a trial. For example, it is anopinion if you say “Cats are better pets than dogsay be true, ”but.Ititmis difficult to prove.Some people may not agree with this opinion but they also cannot prove that they areright.In a trial, a judge must decide which eyewitnesses to believe and which not to believe.The judge does not consider what each eyewitness looks like or where that personlives or works. He/she only cares about whether the eyewitness has given trueinformation, which must be facts rather than opinions. This kind of information iscalled evidence.Unit 2AN INTERVIEWPausanias,who was a Greek writer about 2,000 years ago, has come on amagical journey on March 18th 2007 to find out about the present-day OlympicGames. He is now interviewing Li Yan, a volunteer for the 2008 Olympic Games.P: My name is Pausanias.I li ved in what you call“AncientGreece”and I used towrite about the Olympic Games a long time ago. I’ve come to your time to find outabout the present-day Olympic Games because I know that in 2004 they were held in my homeland. May I ask you some questions about the modern Olympics?L:Good heavens! Have you really come from so long ago? But of courseyou can 103fask any questions you like. What would you like to know?P: How often do you hold your Games?L:Every four years. There are two main sets of Games-the Winter and Summer Olympics, and both are held every four years on a regular basis. The Winter Olympics are usually held two years before the Summer Games. Only athletes who havereached the agreed standard for their event will be admitted as competitors.They may come from anywhere in the world.P:Winter Games? How can the runners enjoy competing in winter? Andwhat about the horses?L: Oh no! There are no running races or horse riding events. Instead there are competitionslike skiing and ic e skating which need snow and ice. That ’s why they called the Winter ’reOlympics. It ’sin the Summer Olympics that you have the running races, together with swimming, sailing and all the team sports.P: I see. Earlier you said that athletes are invited from all over the world. Do you meanthe Greek world? Our Greek cities used to compete against each other just for the honour ofwinning. No other countries could join in, nor could slaves or women!L: Nowadays any country can take part if their athletes are good enough. There areover 250 sports and each on has its own standard. Women are not only allowed,but play a very important role in gymnastics, athletics, team sports and?P:Please wait a minute! All those events, all those countries and evenwomen taking part! Where are all the athletes housed?L:For each Olympics, a special village is built for them to live in, a mainreception building, several stadiums for competitions, and a gymnasium as well.P: That sounds very expensive. Does anyone want to host the Olympic Games?L: As a matter of fact, every country wants the opportunity. It’s a great responsib but also a great honour to be chosen. There ’s as much competition among countries to host the Olympics as to win Olympic medals. The 2008 Olympics will be held in Beijing, China. Did you know that?Oh yes! You must be very proud.L:Certainly. And after that the 2012 Olympics will be held in London. They have alreadystarted planning for it. A new village for the athletes and all the stadiums willbe built to the east of London. New medals will be designed of course and? P:Did you say medals? So even the olive wreath has been replaced! Oh dear!Do you compete for prize money too?L: No, we don’it.’still all about being able to run faster, jump higher and throw’further. That s the motto of the Olympics, you- “knowSifter, Higher and Stronger.”P: Well, that’s good news. How interesting! Thank you so much for your time.THE STORY OF ATLANTAAtlanta was a Greek princess. She was very beautiful and could run faster than any man in Greece. But she was not allowed to run and win glory for herself in the Olympic Games. She was so angry that she said to her father that she would not marry anyone who could not run faster than her. Her father said that she must marry, so Atlanta made a bargain with him. She said to him,"These are my rules. When a man says he wants to marry me, I will run against him. If he cannot run as fast as me, he will be killed. No one will be pardoned."Many kings and princes wanted to marry Atlanta, but when they heard of rules they knew it was hopeless. So many of them sadly went home, but others stayed to run the race. There was a man called Hippomenes who was amazed when he heard of Atlanta's rules,"Why are these men so foolish?" he thought. "Why will they let themselves be killed because they cannot run as fast as this princess?" However, when she saw Atlanta come out of her house to run, Hippomenes changed his mind."I will marry Atlanta--or die!" he said.The race started and although the man ran very fast, Atlanta ran faster. As Hippomenes watched he thought, "How can I run as fast as Atlanta?" He went to ask the Greek Godness of Love for help. She promised to help him and gave him three golden apples. She said," Throw an apple in front of Atlanta when she is running past. When she stops to pick it up, you will be able to run p 103fast her and win."Hippomenes took the apples and went to the King. He said," I want to marry Atlanta ." The King was sad to see another man die, but Hippomenes said," I willmarry her------or die!" So the race began.Unit 3WHO AM I?Over time I have been changed quite a lot. I began as a calculating machine in Francein 1642. Although I was young I could simplify difficult sums. I developed veryslowly and it took nearly two hundred years before I was built as an analyticalmachine by Charles Babbage. After I was programmed by an operator who used cardswith holes, I could“think”logicallyduceandanproanswer quicker than any person.At that time it was considered a technological revolution and the start of my“intelligence”. In 1936 my real father, Alan Turing, wrote a book about how I could bemade to work as a“universal machinesolve”anyto difficult mathematical problem.From then on, I grew rapidly both in size and in brainpower. By the 1949s I hadgrown as large as a room, and I wondered if I would grow any larger. However, thisreality also worried my designers. As time went by, as was make smaller. First as aPC(personal computer) and then as a laptop, I have been used in offices and homessince the 1970s.These changes only became possible as my memory improved. First it was stored intubes, then on transistors and later on very small chips. As a result I totally changed myshape. As I have grown older I have also grown smaller. Over time my memory hasdeveloped so much that, like an elephant, I never forget anything I have been told! Andmy memory became so large that even Icouldn ’t believe it! But I was always so lonelystanding there by myself, until in early 1960s they gave me a family connected by anetwork. I was able to share my knowledge with others through the World Wide Web.Since the 1970s many new applications have been found for my. I have become veryimportant in communication, finance and trade. I have also been put into robots andused to make mobile phones as well as help with medical operations. I have evenbeen put into space rockets and sent to explore the Moon and Mars. Anyhow, mygoal is to provide humans with a life of high quality. I am now truly filled withhappiness that I am a devoted friend and helper of the human race!ANDY –THE ANDROIDI ’m part of an android football team. About once a yearwe are allowed to get togetherto play a game of football. I ’m as big as a human. It fact, I look like one too. On the football team I ’m a striker so I have to be able to run very fast. My computer ships helpme to move and think like a human. For example, I have learned to signal to myteammates in computer language to give me the ball when I am open and havea good for a goal.My first football competition was in Nagoya, Japan several years ago. Last year ourteam went to Seattle, Washington in the USA. We won second place. Personally, Ithink the team that won first place cheated. They had developed a new type of programjust before the competition. So we need to encourage our programmer to improve ourintelligence too. We are determined to create an even better system. In a way ourprogrammer is like our coach. She programs us with all the possible moves she hasseen while watching human games. Then she prepares reliable moves to use if a newsituation arises. In this way I can make up new moves using my“artificialintelligence ”. I could like to play against a human team, for I have been programmed toact just like them. After all, with the help of my electronic brain which never forgetsanything, using my intelligence is what I ’m all about!Unit 4HOW DAISY LEARNED TO HELP WILDLIFEDaisy had always longed to help endangered species of wildlife. One day she woke upand found a flying carpet by her bed.“Where youdo want to go?”it asked. Daisyresponded immediately.“I’d like to see some endangered wildlife,”she said. take me to a distant land where I can find the animal that gave fur to makethis sweater. ”onceAt the carpet flew away and took her to Tibet. There d103faisy saw and antelope looking sad. It said,“We’re being killed for the wool beneathour stomachs. Our fur is being used to make sweaters for people like you. As a result,we are now an endangered species.”At that Daisy cried,“I’m sorry I didn’t knowI wonder what is being done to help you. Flying carpet, please show me a place wherethere ’s some wildlife protection.”The flying carpet traveled so fast that next minute they were in Zimbabwe. Daisyturned around and found that she was being watched by and elephant.“Haveyou“Don’t come to take my photo?”it asked. In relief Daisy burst into laughter.said the elephant,“We used to be an endangered species. Farmers hunted tus withoumercy. They said we destroyed their farms, and money from tourists only went to thelarge tour companies. So the government decided to help. They allowed tourists tohunt only a certain number of animals if they paid the farmers. Now the farmers arehappy and our numbers are increasing. So good things are being done here to savelocal wildlife.”Daisy smiled,“That’s good news. It shows the importance of wildlife protection, but I ’d like to help as the WWF suggests.”The carpet rose again andcealmostthey at on were in a thick rainforest. A monkey watched them as it rubbed itself.doing? ”asked Daisy. “I ’protectingm myself from mosquitoes, it ”replied. When I find a millipede insect, I rub it over my body. It contains a powerful drug which affects mosquitoes. You should pay more attention to the rainforest where I live the appreciate how the animals live together. No rainforest, no animals, no drugs.Daisy was amazed.“Flying carpet, please take me home so I can tell WWF and we can begin producing this new drug. Monkey, please come and help. ”The monkey agreed. The carpet flew home. As they landed, things began to disappear. Two minutes later everything had gone-the monkey, too. So Daisy was not able to make her new drug. But what an experience! She had learned so much! And there was always WWF ?ANIMAL EXTINCTIONMany animals have disappeared during the long history of the earth.The most famousof these animals are dinosaurs.They lived on the earth tens of millions of years ago,long before humans came into being and their future seemed secure at that time.There were many different kinds of dinosaur and a number of them used to live in China.The eggs of twenty-five species have been found in Xixia,County,Nanyang,Henan Province.Not long ago a rare new species of bird-like dinosaur was discoveredin ChaoyangCounty,LiaoningProvince.When scientists inspeacted the bones,they were surprised to find that these dinosaurs could not only run like the others but also climb trees.They learned this from the way the bones were joined together.ut 65 million years ago. Some scientists think it came after an unexpected incident when a huge rock from space hit the earth and put too much dust into the air.Others think the earth got too hot for the dinosaursto live on any more.Nobody knows for sure why and how dinosaursdisappeared from the earth in such a short time.We know many other wild plants, animals,insects and birds have died out more recently.According to a UN report,some 844 animals and plants have disappeared inthe last 500 years.The dodo is one of them.It lived on the Island of Mauritius and was a very friendly animal.Please listen to a story of the dodo and how it disappeared frome the earth.“What are”Unit 5THE BAND THAT WASN’THave you ever wanted to be part of a band as a famous singer or musician? Haveyou ever dreamed of playing in front of thousands of people at a concert, at which everyone is clapping and appreciating your music? Do you sing karaoke andpretend you are a famous singer like Song Zuying or Lin Huan? To be honest, a lotof people attach great importance to becoming rich and famous. But just how dopeople form a band?Many musicians meet and form a band because they like to write and playtheir own music. They may start as a group of high-school students, for wh bacom practicing their music in someone ’s hours is the first step to fame. Sometimes they may play to passers-by in the street or subway so that they can earn some extra moneyfor themselves or to pay for their instruments. Later they may give performances inpubs or clubs, for which they are paid in cash. Of course they hope to make records in a studio and sell millions of copies to become millionaires!However, there was one band hat started in a different way. It was called theMonkees and began as a TV show. The musicians were to play jokes on each otheras well as play music, most of which was based loosely on the beatles. The TV organizers had planned to find four musicians who could act as well as sing. They putan advertisement in a newspaper looking for rock musicians, but they could only findone who was good enough. They had to use actors for the other three members of the band.As some of these actors could not sing well enough, they had to rely on othermusicians to help them. So during the broadcasts they just pretended to sing.Anyhow their performances were humorous enough to be copied by clubs in orderto get more familiar with them. Each week on TV, the Mondees would play and singsongs written by other musicians. However, after a year or so in which they became more serious about their work, the Monkees started to play and sing their own songs like a real band. Then they produced their own records and started touring and play their own music. In the USA they became even more popular than the Beatles and sold even more records. The band broke up about 1970, but happily the reunited in the mid-1980s. they produced a new record in 1996, with which they celebrated their former time as a real band.FREDDY THE FROG(II)Not long after Freddy and the band became famous,they visited Britain on a brief tour.Fans showed their devotion by waiting for hours to get tichkets for their concerts.Freddy was now quite confident when he went into a concert hall.He enjoyed singing and all the congratulations afterwards!His most exciting invitation was to perform on a programme called "Top of the Pops."He had to go to London,wear an expensive suit and give a performance to a TV camera.It felt very strange.But as soon as the programme was over,the telephones which were in the same room started ringing.Everybody was asking when they could see Freddy and his band again. They were truly stars.Then things went wrong.Freddy and his band could not go out anywhere without being followed.Even when they wore sunglasses or beards people recognized them. Fans found them even when they went into the toilet.They tried to hide in the reading rooms of libraries,but it was useless.Someonewas always there!Their personal life was regularly discussed by people who did not know them but talked as if they were close friends. At last feeling very upset and sensitive,Freddy and his band to which they were never to return,and went back to the lak 5e.。

[语法详解] 一、定语从句的种类 根据定语从句与先行词之间关系的紧密程度，我们将定语 从句分为限制性定语从句和非限制性定语从句两种。
二、定义 1．限制性定语从句：限制性定语从句是先行词在意义上不可 缺少的定语，用于修饰和限定先行词。如果去掉，主句的意思就 不完整。 ①This is the computer (that/which) he bought for his son yesterday. 这是他昨天为儿子买的电脑。 ②Here is the man (whom/who/that) you've been expecting to meet. 这就是你一直想要见的人。 ③The woman who/that survived the earthquake is Amy's English teacher. 在地震中幸存的那个女人是埃米的英语老师。

2．非限制性定语从句：非限制性定语从句和主句的关系不是 十分密切，只是对先行词或主句作些附加说明，如果去掉，主句 的意思仍然完整。这种从句和主句之间往往用逗号分开。 ①Our foreign teacher, who is a Canadian, teaches us in a very interesting way. 我们的外教，一个加拿大人，用很有趣的方式给我们上课。 ②Tom, whose father is one of my old friends, came to see me from London. 汤姆是我的一个老朋友的儿子，他从伦敦来看我。
③I heard a terrible noise, which brought my heart into my mouth.(which代替noise) 我听到了一个可怕的声音，这使我非常害怕。 ④Most people didn't vote for him, which disappointed him.(which代替整个主句的内容) 大多数人没有投票支持他，这使他感到失望。
12．The way that/in_which he worked out the problem is worth considering. 13．The weather turned out to be very cold, which was more than we could expect. 14．I live next door to a couple whose children often make a lot of noise. 15．We will put off the picnic in the park until next week, when the weather may be better.
2．非限制性定语从句的关系代词无论指“物”还是指 “人”，都不能用that。指人时，如果关系词在从句中作主语，则 用who，作宾语则用whom；指物时要用which。关系代词在从句中 作宾语也不能省略。 Holly, who is from Australia, has a good command of Chinese. 霍莉来自澳大利亚，她精通汉语。 The book, which my mother bought for me yesterday, is very interesting. 这本书很有意思，这是我妈妈昨天为我买的。
3．The film, which_I_saw_a_few_days_ago,_is well worth seeing. 这部电影很值得一看，我几天前看过。 4．Her sister who_teaches_us_English will go abroad next year. 她教我们英语的姐姐明年将出国。 5．The house (that/which)_I_bought_last_month has got a beautiful garden. 我上个月买的那幢房子有一个漂亮的花园。
5．(教材P2)Later, Catherine Ⅱ had the Amber Room moved to a palace outside St Petersburg where she spent her summers. 6．(教材P2)This was a time when the two countries were at war. 7．(教材P5)A fact is anything that can be proved. 8．(教材P7)I think highly of those who are searching for the Amber Room.
