Unit1 How can we become good learners?P3 3aHow I Learned to Learn English Last year, I did not like my English class. Every class was like a bad dream. The teacher spoke too quickly that I did not understand her most of the time. I was afraid to ask questions because my poor pronunciation. I just hid behind my textbook and never said anything.Then one day I watched an English movie called Toy Story. I fell in love with this exciting and funny movie! So I began to watch other English movies,too. Although I could not understand everything the characters said, their body language and the expressions on their faces helped me to get the meaning. I also realized I could get the meaning by listening for just the key words. My pronunciation also improved by listening to the conversations in English movies. I discovered that listening to something interesting is the secret tolanguage learning. I also learned useful sentences like “It’s a piece of cake” or “It serves you right.” I did not understand these sentences at first. But because I wanted to understand the story, I looked up the words in a dictionary.Now I really enjoy my English class. I want to learn new words and more grammar so that I can have a better understanding of English movies.Unit1 How can we become good learners?P6 2bHow Can You Become a Successful Learner?Everyone is born with the ability to learn. But whether or not you can do this well depends on your learning habits. Research shows that successful learners have some good habits in common.Creating an interest in what they learnStudies show that if you are interested in something, your brain is more active and it is also easier for you to pay attention to it for a long time. Good learners oftenconnect what they need to learn with something they are interested in. For example, if they need to learn English and they like music or sports, they can listen to English songs or watch sports programs in English. This way they will not get bored.Practicing and learning from mistakesGood learners think about what they are good at and what they need to practice more. Remember, “use it or lose it”! Even if you learn something well, you will forget it unless you use it. Practice makes perfect. Good learners will keep practicing what they have learned,and they are not afraid of making mistakes. Alexander Graham Bell did not invent the telephone overnight. He succeeded by trying many times and learning from his mistakes.Developing their study skillsIt is not enough to just study hard. Good learners know the best way they can study. For example, they may take notes by writing down key words or by drawingmind maps. They also look for ways to review what they have learned. They may do this by reading their notes every day or by explaining the information to another student.Asking questionsGood learners often ask questions during or after class. They even ask each other and try to find out the answers. Knowledge comes from questioning. Learning is a life-long journey because every day brings something new. Everything that you learn becomes a part of you and changes you, so learn wisely and learn well.Unit 2 I think that mooncakes are delicious!P11 3aFull Moon, Full FeelingsChinese people have been celebrating Mid-Autumn Festival and enjoying mooncakes for centuries. Mooncakes are in the shape of a full moon onMid-autumn night. They carry people’s wishes to the families theylove and miss.There are many traditional folk stories about this festival. However, most people think that the story of Chan g’e is the most touching. Chang’e was Hou Yi’s beautiful wife. After Hou Yi shot down the nine suns, a goddess gave him a magic medicine to thank him. Whoever drank this could live forever, and Hou Yi planned to drink it with Chang’e. However, a bad man, Peng Meng, tried to steal the medicine when Hou Yi was not home. Chang’e refused to give it to him and took it all. She became very light and flew up to the moon. Hou Yi was so sad that he called out her name to the moon every night. One night, he found that the moon was so bright and round that he could see his wife there. He quickly laid out her favorite fruits and desserts in the garden. How he wished that Chang’e could come back!After this, people started the tradition of admiring the moon and sharing mooncakes with their families.Unit 2 I think that mooncakes are delicious!P12 4bDear Xia Yu,Do you know that there are two special days for parents in America? One is Mother’s Day on the second Sunday of May, and the other is Father’s Day on the third Sunday of June. On these two days, American children often give gifts to their parents or take them out for lunch or dinner. Common gifts are flowers and cards for mothers and shirts or ties for fathers. I heard that it is becoming more and more popular t o celebrate Mother’s Day and Father’s Day in China. I wonder if children over there also give similar gift s to their parents. I believe that there are many ways to show our love. Actually, we don’t have to spend a lot of money. It is also a good idea to help parents to do something instead.JuneUnit 2 I think that mooncakes are delicious!P14 2bThe Spirit of ChristmasMany would agree that when we think of Christmas, we probably think of gifts, Christmas trees and Santa Claus. But behind all these things lies the true meaning of Christmas: the importance of sharing and giving love and joy to people around us.The story in A Christmas Carol is perhaps the best example of this.A Christmas Carol is a famous short novel written by Charles Dickens. It is about an old man named Scrooge who never laughs or smiles. He is mean and only thinks about himself.He doesn’t treat others nicely. He just cares about whether he can make more money And he hates Christmas. One Christmas Eve, Scrooge sees the ghost of Jacob Marley, his dead business partner. Marley used to be just like Scrooge, so he was punished after he died. He warns Scrooge to change his ways if he doesn’t want to end up like him. He also tells Scrooge to expect three spirits to visit him.That night, three ghosts visit Scrooge. First, the Ghost of Christmas Past takes him back to his childhoodand reminds Scrooge of his happier days as a child. Then the second spirit, the Ghost of Christmas Present, takes him to see how others are spending Christmas this year. Everyone is happy, even poor people. The last one, the Ghost of Christmas Yet to Come, takes him to the future. He sees that he is dead but nobody cares. He is so scared that he wakes up in his bed and finds out it is only the next morning----Christmas Day!He decides to change his life and promises to be a better person. He happily celebrates Christmas with his relatives. He also gives gift s to people in need. He now treats everyone with kindness and warmth, spreading love and joy everywhere he goes. And that is the true spirit of Christmas!Unit3 Could you please tell me where the restrooms are?P19 3aFun Times Park — Always a Fun Time![Alice and He Wei are in Space World]Alice: I wonder where we should go next.He Wei: How about that new ride over there?Alice: Oh ... it looks scary.He Wei: Come on! I promise it’ll be exciting! If you’re afraid, just shout or hold my hand.[After the ride]Alice: You were right, that was fun! I was scared at first, but shouting did help.He Wei: See, that wasn’t so bad, right? You never know until you try something.Alice: Yes, I’m so glad I tried it.He Wei: Do you want to go to Water World now?Alice: Sure, but I’m getting hungry. Do you know where we can get some good food quickly?He Wei: Of course! I suggest Water City Restaurant in Water World. It’s a fast food place. It serves delicious food.Alice: Great!Let’s go![On their way to Water City Restaurant, Alice and He Wei pass by Uncle Bob’s.]Alice: Look! This restaurant looks interesting. The sign says a rock band plays there every evening.He Wei: Why don’t we come back here for dinner later?Let’s ask what time the band starts playing.[Alice and He Wei walk up to a staff person at the door.]He Wei: Excuse me, could you tell us when the band starts playing this evening?Staff: Eight o’clock. Th e restaurant is always busy at that time, so come a little earlier to get a table.He Wei: OK, thanks!Unit3 Could you please tell me where the restrooms are?P22 2bCould You Please ...?When you visit a foreign country, it is important to know how to ask for help politely. For example, you may ask“Where are the restrooms?” or “Could you please tell me where the restrooms are?” These are similar requests for directions. Both are correct English, but the first one sounds less polite. That is because it is a very direct question. It is not enough to just ask a question correctly. We also need to learn how to be polite when we ask for help.Good speakers change the way they speak in different situations. The expressions they use might depend on whom you are speaking to or how well they know each other. However If you say to your teacher, “When is the school trip.’’, this might sound impolite. But if you say, “Excuse me, Mr. West. Do you know when the school trip is?’’, th is will sound much more polite.Usually polite questions are longer.They include expressions such as “Could you please ...?” or “May I ask ...?” It sounds more polite to say, “Peter, could you please tell me your e-mail address?” than “Peter, tell me your e-mail address.” Sometimes we even need to spend time leading into a request. For example, we might first say a stranger, “Excuse me, I wonder if you can help me” or “I’m sorry to trouble you, but ...” before asking for help.It might seem more difficult to speak politely than directly. However, it is important to learn how to use the right language in different situations. This will help you communicate better with other people.Unit 4 I used to be afraid of the dark.P27 3aFrom Shy Girl to Pop Star1 F or this month’s Young World magazine, I interviewed 19-year-old Asian pop star Candy Wang. Candy told me that she used to be really shy and took up singing to deal with her shyness. As she got better, she dared to sing in front of her class, and then for the whole school. Now she’s not shy anymore and loves singing in front of crowds.2 I asked Candy how life was different after she became famous. She explained that there are many good things, like being able to travel and meet new people all the time. “I didn’t use to be popular in school, but now I get tons of attention everywhere I go.” However, too much attention can also be a bad thing. “I always have to worry about how I appear to others and I have to be very careful about what I say or do. And I don’t have much private time anymore. Hanging out with friends is almostimpossible for me now because there are always guards around me.”3 What does Candy have to say to all those young people who want to become famous? “Well,” she begins slowly, “you have t o be prepared to give up your normal life. You can never imagine how difficult the road to success is. Many times I thought about giving up, but I fought on. You really require a lot of talent and hard work to succeed. Only a very small number of people ma ke it to the top.”Unit 4 I used to be afraid of the dark.P30 2bHe Studies Harder Than He Used toLi Wen is a normal 15-year-old boy from the countryside. He works hard and does well in school.It is hard to believe that he used to have difficulties in school.When he was a little boy,he seldom caused any problems,and his family spent a lot of time together.However things began to change a few yearsago.His parents moved to the city to look for jobs,and his grandparents came to take care of him.But he missed his parents so much and often felt lonely and unhappy.Li Wen’unhappiness began to influence his schoolwork. He became less interested in studying. Sometimes He was absent from classes and failed his examinations. Finally, his parents made the decision to send him to a boarding school.However Li Wen was shy and not able to make friends quickly in school.He found life there difficult.One day, he told his teacher he wanted to leave the school. His teacher was worried about him and she called his parents.She advised them to talk with their son in person. So his parents took a 24-hour train and a 5-hour bus ride to get to Li Wen’school.They had a long talk. “It was exactly what I needed,” he said. “Now I understand even though they are busy,they are always thinking of me. they take pride in everything good that I do.”After that,Li Wen’parents had much more communication with their son than they used to.Now Li Wen has become more outgoing and made some good friends in school.He has even joined the school basketball team and become active in many other activities.“I’m much happier now,and I work even harder than I used to.I know my parents love me and they’re always proud of me,”says Li Wen. “It’s very important for parents to be there for their children.”Unit5 What are the shirts made of?P35 3aThe Difficult Search for American Products in the US If you go to another country, what kinds of things would you buy? Would you buy a camera in Japan, some beautiful clothes in France, or a watch in Switzerland? No matter what you may buy, you might probably think those products were made in those countries. However, you could be wrong. Kang Jian is a 17-year-old student from Shanghai. Last year he went to visit his aunt anduncle in San Francisco. He found it interesting that so many products in the local shops were made in China. “I wanted to buy a toy car for my cousin, but even though most of the toys had American brands, they were made in China.”Toys are not the only things made in China. “I wanted to buy a pair of basketball shoes,” he explains. “But I had to visit five or six stores before finding a pair made in America!” He realized that Americans can hardly avoid buying products made in China. “In fact,” he continues, “there were many other things there made in China —footballs, handbags, pet food, mobile phones. Even American flags are made in China!” Kang Jian thinks it’s great that China is so good at making these everyday things. However, he wishes that in the future China will also get better at making high-technology products that people can buy in all parts of the world.Unit5 What are the shirts made of?P38 2bBeauty in Common ThingsEach different part of China has its own special forms of traditional art. These usually try to show the things that are important in life such as love, beauty and family. The most common things, from paper to clay to bamboo, are turned into objects of beauty.According to Chinese history, sky lanterns were first used by Zhuge Kongming. He sent them out to ask for help when in trouble. Today, sky lanterns are used at festivals and other celebrations. They are made of bamboo and covered with paper. When the lanterns are lit, they slowly rise into the air like small hot-air balloons for all to see. They are seen as bright symbols of happiness and good wishes.Paper cutting has been around for over 1,500 years. Paper cutting sounds very easy but it can be difficult to do. The paper, usually red, is folded before it is cut with scissors. The most common pictures are flowers, fish, animals, and things about Chinese history. During theSpring Festival, they are put on windows, doors and walls as symbols of wishes for good luck and a happy new year.Chinese clay art is famous because the clay pieces are so small but they look very real. The pieces are usually cute children or lively characters from a Chinese fairy tale or historical story. The pieces are carefully shaped by hand from a very special kind of clay and then allowed to air-dry. After drying, they are fired at a very high heat. They are then polished and painted. It takes several weeks to complete everything. These small pieces of clay art show the love that all Chinese people have for life and beauty.Unit 6 When was it invented?P43 3aAn Accidental InventionDid you know that tea, the most popular drink in the world (after water), was invented by accident? Many people believe that tea was first drunk nearly 5,000 years ago. It is said that a Chinese ruler called Shen Nong was the first to discover tea as a drink. One day Shen Nong was boiling drinking water over an open fire. Some leaves from a tea plant fell into the water and remained there for some time. It produced a nice smell so he tasted the brown water . It was quite delicious.,and so,one of the world’s favorite drinks was invented.A few thousand years later, Lu Yu, “the saint of tea”, mentioned Shen Nong in his book Cha Jing. The book describes how tea plants were grown and used to make tea. It also discusses where the finest tea leaves were produced and what kinds of water were used.It is believed that tea was brought to Korea andJapan during the 6th and 7th centuries. In England, tea didn’t appear until around 1660, but in less than 100 years later, it had become the national drink. The tea trade from China to Western countries took place in the 19th century. This helped to spread the popularity of tea and the tea plant to more places around the world. Even though many people now know about tea culture, the Chinese are without doubt the ones who best understand the nature of tea.Unit 6 When was it invented?p46 2bDo You Know When Basketball Was Invented?Basketball is a much-loved and active sport that is enjoyed by many for fun and exercise.It is over 100 years old and is played by more than 100 million people in over 200 countries. It’s believed that the first basketball game in history was played on December 21,1891.Then in 1936 in Berlin,it become an event at the Olympics.Basketball was invented by a Canadian doctornamed James Naismith, who was born in 1861. When he was a college teacher, he was asked to think of a game that could be played in the winter. Dr. Naismith created a game to be played inside on a hard floor. Dr. Naismith divided the men in his class into two teams and taught them to play his new game. Players on the same team must work together to help each other get the ball in the other team’s basket. At the same time, they need to stop the competing team from getting the ball into their own basket.Today, the popularity of basketball has risen around the world, with many young people dreaming of becoming famous players. In China, you can sometimes see people playing basketball in parks, schools and even in factories. Basketball has not only become a popular sport to play, it has also become a more popular sport to watch.Although America’s NBA games are the most famous, the CBA games are becoming popular in China.The number of foreign players, including Chinese players, in the NBA has increased. there are also more and more foreign players in the CBA. Many young people look up to these basketball heroes and want to become like them. These stars encourage young people to work hard to achieve their dreams.Unit7 Teenagers should be allowed to choosetheir own clothes.P51 3aMom Knows BestWhen I was a tiny baby crying all night, my mom sang to me and stayed by my sideWhen I was tired and hungry, she gave me food and warm arms to sleep inWhen I was two running through the field, she made sure I was safe and kept me from dangerWhen I fell and hurt myself, she gave me a hug and lifted me upWhen I was seven coughing badly, she said noice-cream for meBut I talked back loudly, “I should be allowed to eat some! Give it to me now!”When I was nine watching scary movies, she said it’d give me awful dreamsBut I shouted back angrily, “I should be allowed towatch it! I’m not a baby!”When I was a teen going out with friends, she said, “Please be back by ten!”But I talked back again —“I should not be told what to do! I’m seventeen now!”Now I’m an adult, thinking back to those timesI coughed for days after eating that ice-creamAnd had scary dreams after watching that filmI was late for school from staying out past tenI regret talking back, not listening to MomMom knows best, and for me she wanted only the best!Unit7 Teenagers should be allowed to choosetheir own clothes.P54 2bShould I Be Allowed to Make My Own Decisions?Many teenagers have hobbies. But sometimes these can get in the way of their schoolwork, and parents might worry about their success at school. Teenagers often think they should be allowed to practice their hobbies as much as they want. Do you agree?Liu Yu, a fifteen-year-old boy from Shandong, is a running star. He is on his school team and has always wanted to be a professional runner when he grows up. However, his parents won’t allow him to train so much. “Of course we want to see him achieve his dreams,” says Mr. Liu. “And we know how much he loves running. My wife and I have supported every one of his races. We have nothing against running! But we think our son needs to think about other possible jobs. He’s getting older now, so he needs to think about what will happen if he doesn’tend up a professional runner.”Liu Yu doesn’t really agree. “Well, I think I shou ld be allowed to decide for myself,” he says. “My parents have always taught me how important it is to work hard at school and enter university. I understand this, but I’m serious about running. It’s the only thing I’ve ever wanted to do.”His parents believe that Liu Yu should study hard in the evenings so they don’t allow him to practice running at night. “Maybe he thinks it’s too strict or unfair,” says Mrs. Liu. “But we think we’re doing the right thing. He needs to spend more time on his homework because it is difficult to become a professional sports star.”But Liu Yu still disagrees. “I know my parents care about me. They always talk about what will happen if I don’t succeed. But I will! I’m a quick runner! I think I should be allowed to make this choice myself. Only then will I have a chance to achieve my dream.”Unit8 It must belong to Carla.P59 3aWe live in a small town and almost everyone knows each other. It used to be very quiet.Nothing much ever happened around here. However, these days, something unusual is happening in our town. Victor, a teacher at my school, is really nervous. When he was interviewed by the town newspaper, he said, “Every night we hear strange noises outside our window. My wife thinks that it could be an animal, but my friends and I think it must be teenagers having fun. My parents called the policemen, but they couldn’t find anything strange. They think it might be the wind. I don’t think so!”Victor’s next-door neighbor Helen is worried, too. “At first, I thought that it might be a dog, but I couldn’t see a dog, or anything else, either. So I guess it can’t be a dog. But then, what could it be?” One woman in the area saw something running away, but it was dark so she is not sure. “I think it was too big to be a dog,” she s aid.“Maybe it was a bear or a wolf.”Everyone in our town is feeling uneasy, and everyone has his or her own ideas. There must be something visiting the homes in our neighborhood, but what is it? We have no idea. Most people hope that this animal or person will simply go away, but I do not think that is going to happen. The noise-maker is having too much fun creating fear in the neighborhood.Unit8 It must belong to Carla.P62 2bStonehenge — Can Anyone Explain Why It Is There?Stonehenge, a rock circle, is not only one of Britain’s most famous historical places but also one of its greatest mysteries. Every year it receives more than 750,000 visitors. people like go to this place Especially in June as they want to see the sun rising on the longest day of the year.For many years, historians believed Stonehenge wasa temple where ancient leaders tried to communicate with the gods. However, historian Paul Stoker thinks this can’t be true because Stonehenge was built so many centuries ago. “The leaders arrived in England much later,” he points out.Another popular idea is that Stonehenge might be a kind of calendar. The large stones were put together in a certain way. On midsummer’s morning, the sun shines directly into the center of the stones. Other people believe the stones have a medical purpose. They think the stones can prevent illness while keeping people healthy. “As you walk there, you can feel the energy from your feet move up your body,” said one visitor. No one is sure what Stonehenge was used for, but most agree that the position of the stones must be for a special purpose. Some think it might be a burial place, or a place to honor ancestors. Others think it was built to celebrate a victory over an enemy.Stonehenge was built slowly over a long period oftime. Most historians believe it must be almost 5,000 years old. One of the greatest mysteries is how it was built because the stones are so big and heavy. In 2001, a group of English volunteers tried to build another Stonehenge, but they couldn’t. “We don’t really know who built Stonehenge,” says Paul Stoker. “And perhaps we might never know, but we do know they must have been hardworking —and great planners!”Unit 9 I like music that I can dance to.P67 3aWhat Do You Feel Like Watching Today?While some people only stick to one kind of movie, I like to watch different kinds depending on how I feel that day.When I’m down or tired, I prefer movies that can cheer me up. Comedies like Men in Black or cartoons like Kungfu Panda have funny dialog and usually have a happy ending. The characters may not be perfect, but they try their best to solve their problems. After I watchthem, my problems suddenly seem less serious and I feel much better again. Laughing for two hours is a good way to relax!I don’t watch dramas or documentaries when I’m sad or tired. Dramas like Titanic make me feel even sadder. Documentaries like March of the Penguins which provide plenty of information about a certain subject can be interesting, but when I’m tired I don’t want to th ink too much. I don’t mind action movies like Spider-Man when I’m too tired to think. I can just shut off my brain, sit back and enjoy watching an exciting superhero who always saves the world just in time.Once in a while, I like to watch movies that are scary.They can be fun, but I’m too scared to watch them alone. I always bring a friend who isn’t afraid of these kinds of movies,and it doesn’t feel so scary anymore.Unit 9 I like music that I can dance to.P70 2bSad but BeautifulLast night one of my Chinese friends took me to a concert of Chinese folk music. The piece which was played on the erhu especially moved me. The music was strangely beautiful, but under the beauty I sensed a strong sadness and pain. The piece had a simple name,Erquan Yingyue(Moon Reflected on Second Spring), but it was one of the most moving pieces of music that I’ve ever heard. The erhu sounded so sad that I almost cried along with it as I listened. Later I looked up the history of Erquan Yingyue, and I began to understand the sadness in the music.The music was written by Abing, a folk musician who was born in the city of Wuxi in 1893. His mother died when he was very young. Abing’s father taught him to play many musical instruments, such as the drums, dizi and erhu, and by age 17, Abing was known for his musical ability. However, after his father died, Abing’s life grew worse. He was very poor.Not only that,he developed a serious illness and became blind. For several。
