Californian cities over the next decade.The tree planting campaign is an attempt to deflate what's being called the Greenhouse Effect.Scientists believe that the earth is getting warmer because of an accumulation of carbon dioxide in the air.Trees take carbon dioxide out of the air.

Martin Rosen is the director of the Trust for Public Land,the organization that is coordinating the state-wide tree planting effort."Time is not neutral.We are so rapidly depleting the atmosphere,we are so rapidly changing the climate,that unless we start now the situation may well become irreversible."

Some movie stars were on hand for the tree planting ceremony.Actor Peter Cyote served as the master of ceremonies."Unless the environmental movement comes into everybody's life,in real simple activities,it's not going to work.Planting a tree is real simple.So I want to participate in something that is really accessible to the citiz en,just to everyday people,to children.So that as citiz ens we can do a lot.'After Peter Cyote introduced a few speakers and a couple of songs were sung the ceremony moved over to a corner of the park where a group of youngsters planted a Copper Beech tree.

Isobel Wade is the state coordinator for Campaign California Re-leaf.Wade says the tree plantings are important because they will help clean up the carbon dioxide in the atmosphere,improve the environment and make neighborhoods more attractive,but Isobel Wade cautions it isn't w w w .k h d a w .c o m 课后答案

3.In some cases,recycling could be haz ardous to the environment if

established.Sometimes we become complacent when it comes to recycling,but when you speak in terms of actual facts and figures that everyone can understand,people become more cognizant of the problem.I remember reading one time that the energy saved from one recycled can can provide enough power to operate the television for three hours.Give the public information they can grasp,and then you will increase your chances of gaining followers.

Second,technological progress has been made on many fronts.One breakthrough has been the development of a new manufacturing process to help remove ink from paper in more energy efficient and environmentally safe methods.Recycling paper materials can be expensive in both monetary and environmental terms.The difficulty in removing print from paper,the amount of energy expended during the process,and caustic waste that is sometimes produced are costs that companies incur that are then passed on to the consumer.The final key is to increase demand for the growing surplus of resources waiting to be recycled.This problem has appeared in various regions of the world where the technology to process the used materials

lags far behind the amount being collected for recycling.

Recycling is a crucial link protecting our planet.The three keys mentioned are important ways to achieve this end.w w w .k h d a w .c o m 课后答案网

Unit5 Section One Tactics for Listening
Part2 listening and Note-taking Reading
B: When should a child start learning to read and write? This is one of the questions I am most frequently asked. There is no hard and fast rule, for no two are alike, and it would be wrong to set a time when all should start being taught the ins and outs of reading letters to form words.
If a three-year-old wants to read (or even a two-year-old for that matter), the child deserves to be given every encouragement. The fact that he or she might later be "bored" when joining a class of non-readers at infant school is the teacher's affair. It is up to the teacher to see that such a child is given more advanced reading material.
Similarly, the child who still cannot read by the time he goes to junior school at the age of seven should be given every help by teachers and parents alike. They should make certain that he is not dyslexic*. If he is, specialist help should immediately be sought.
Although parents should be careful not to force youngsters aged two to five to learn to read (if badly done it could put them off reading for life) there is no harm in preparing them for simple recognition of letters by labelling various items in their room. For instance, by a nice piece

Unit 6-Conversation 1 Janet: What are you reading, Kate Kate:Alice in Wonderland, by Lewis Carroll. Do you know it Janet: I've heard of it, yes, but I've never read it. It's a 19th century children's story, isn't it K a te: That's right. It's very famous. It's set in Oxford. It starts with this young girl sitting on a river bank. The interesting thing is, the author, Lewis Carroll, he was an Oxford professor and he used to have tea with the girl's family on this river bank. Ja net: Oh, that's fascinating! I'll put it into my diary. Kate: Is that what you're writing I know you've been keeping a diary all the year. Janet: It's been a great year. I've had such a good time — so lucky to have Mark and Kate as friends. Feel I've been doing well with work. Much happier about asking questions in tutorials. Janet: My screen's gone dark. Mark: You're using the battery, remember. It's run out, obviously. Janet: It can't be the battery. It's still charged. Oh no it's still black. Oh dear, I hope it's nothing serious. I haven't backed anything up recently. Kate: That's not like you, Janet. Janet:I know, but I lost my memory stick. I really should have backed things up. How stupid of me not to do that! Supposing I've lost everything! Mark: Let me take a look. The power is still on. And also the operating system still seems to be working ... I think it has to be the graphics card ... But maybe that's not the problem ... Janet: If only I'd backed things up! Kate: Relax, Janet! We'll take it to the computer shop this afternoon. I'm sure it'll be OK. Janet: I hope so. Unit 6-Conversation 2 Janet: Tell me about Alice in Wonderland. Kate: I tell you what, I'll read it to you. Kate: Alice was beginning to get very tired of sitting by her sister on the bank and having nothing to do: Once or twice, she had peeped into the book her sister was reading, but it had no pictures or conversations in it, "and what is the use of a book," thought Alice, "without pictures or conversation" So she was considering in her own mind (as well as she could, for the hot day made her feel very sleepy and stupid) ... Janet: Kate, Mark, where are you going You've got my laptop! Kate: It's all right, Janet, we're taking it to the computer shop. We'll be back soon. Mark: It's not like Janet to forget to back up her work. Kate: She should have been more careful. Janet: It was stupid of me, I know! Stupid, stupid! Janet: Oh! It was a dream! What a relief! Kate: You were talking in your sleep. Janet: What was I saying Kate: "Stupid, stupid." M ark: I've sorted out your computer. Janet: Have you Oh, thank goodness! What was the problem Mark:It was the graphics card, as I predicted ... Janet: Is that what it was! I'm so relieved! Thanks, Mark. Kate: He's great, isn't he Janet: Yes. So are you, Kate. Kate: You're such a good friend. Unit 6-Outside view Computers are a very important part of our lives. They tell us about delays to transport. They drive trains, analyze evidence and control buildings. Did you know that 60 per cent of homes in Britain have got a PC (a personal computer) For many young people, playing computer games is their favorite way of spending spare time. Computers are a very important part of most areas of life in Britain-libraries, the police and in school. But they are becoming more important in our homes as well. They’ll even control the way we live-in “smart homes” or computer-controlled houses. The smart home is now a real possibility. It will become very common. A central computer will adjust the temperature, act as a burglar alarm and switch on lights, ready for you to come back home. And of course you will be able to give new instructions to the computer from your mobile phone. So if your plans change, your home will react to match. Many homes have got lots of televisions and several computers. The smart home will provide TV and Internet sockets in every room, so you’ll be able to do what you want whenever you want. If the temperature outside changes, the smart home will adjust the temperature levels inside. The computer will also close the blinds when it gets dark or to stop so much sun from entering a room. And if you want to eat when you get home, the computer will turn the oven on for you! Are computers taking over our lives In a survey, 44 per cent of young people between 11 and 16 said their PC was a trusted friend. Twenty per cent said they were happier at their computer than spending time with family or friends. Another survey found that people in Britain spend so much time on the phone, texting and reading emails that they no longer have time for conversation.

Part 2 Listening and Note-Taking Mountain Rescue Service / When an accident is reported to the Mountain Rescue Service the first thing that happens is that the person who reports the accident is closely questioned. The rescue group needs to find out a number of details. First, they need to know exactly where the accident happened, with a map reference if possible. Then they will want to know the time of the accident. They will also need to know how many people were involved in the accident and what kind of injuries there were. Finally, they will ask for other useful details, such as the colour of the victim's clothing and the weather conditions. Then the rescue team's call-out procedure begins. Team members keep their personal equipment at home so as to be ready to set off within fifteen minutes of receiving the call. The advance party of about four people sets off right away. They carry a radio telephone with them to send details to the main party and to the base. They are also equipped and trained to give immediate medical assistance. The main party follows the advance party. They carry a radio telephone and more supplies, including a stretcher for the victim. The third party on the mountain is the back-up group. Their job is to help the main party on its return journey. Rescue control is set up in a mobile base. This vehicle carries the team's supplies other than personal equipment.

Many Asian cultures have included frog legs in their diets for centuries -- or at least until they have run out of frogs. But the most famous frog-eaters, and the people who inspired frog-eating in Europe and the United States are the French. By 1977 the French government, so concerned about the scarcity of its native frog, banned commercial hunting of its own amphibians. So the French turned to India and Bangladesh for frogs. As happened in France, American frog-leg fanciers and restaurants also turned increasingly to frozen imports. According to figures collected from government agencies, the United States imported more than million pounds of frozen frog meat each year between 1981 and 1984. So many frozen frog legs were exported from India to Europe and the United States. One of the attractions of Indian frogs, apart from the fact that they have bigger legs than French frogs, was the price. In London, a pound of frozen frog's legs from India cost about ￡, compared with ￡for the French variety. Indian scientists have described as "disastrous" the rate at which frogs are disappearing from the rice fields and wetlands, where they protect crops by devouring damaging

Book 2 Chapter 1 The Population Today we’re going to talk about population in the United States. According to the most recent government census, the population is 281,421,906 people. Now this represents an increase of almost 33 million people since the 1990 census. A population of over 281 million makes the United States the third most populous country in the whole world. As you probably know, the People’s Republic of China is the most populous country in the world. But do you know which is the second most populous? Well, if you thought India, you were right. The fourth, fifth, and sixth most populous countries are Indonesia, Brazil, and Pakistan. Now let’s get back to the United States. Let’s look at the total U. S. population figure of 281 million in three different ways. The first way is by race and origin; the second is by geographical distribution, or by where people live; and the third way is by the age and sex of the population. First of all, let’s take a look at the population by race and origin. The latest U. S. census reports that percent of the population is white, whereas percent is black. Three percent are of Asian origin, and 1 percent is Native American. percent of the population is a mixture of two or more races, and percent report themselves as “of some other race”. Let’s make sure your figures are right: OK, white, percent; black, percent; Asian, 3 percent; Native American, 1 percent; a mixture of two or more races, percent; and of some other race, percent. Hispanics, whose origins lie in Spanish-speaking countries, comprise whites, blacks, and Native Americans, so they are already included in the above figures. It is important to note that Hispanics make up percent of the present U.S. population, however. Finally, the census tells us that 31 million people in the United States were born in another country. Of the 31 million foreign born, the largest part, percent are from Mexico. The next largest group, from the Philippines, number percent. Another way of looking at the population is by geographical distribution. Do you have any idea which states are the five most populous in the United States? Well, I’ll help you out there. The five most populous states, with population figures, are California, with almost 34 million; New York, with 21 million; Texas, with 19 million; and Florida, with 16 million; and Illinois with million people. Did you get all those figures down? Well, if not, I’ll give you a chance later to check your figures. Well, then, let’s move on. All told, over half, or some 58 percent of the population, lives in
