But is it the truth? And what makes students happy or unhappy?To find out the answers, Li Jiahui, a student in Pinggu No. 3 Middle School, Beijing, spent six months studying students’sense(感受) of happiness last year. The 15-year-old girl made a survey with questions such as “Are you feeling happy?”and “What makes you unhappy?”After studying the answers from 284 students, Li learned that about 40 percent（百分之）of the students feel unhappy, and the pressure from studies is the main reason for their unhappiness. “More than 50 percent said they were under pressure and 70 percent didn’t get enough sleep,” Li said. “It shows that middle school students are not as happy as people think. They worry a lot, and they can get angry easily.”Li also said that over 90 percent say their happiness has nothing to do with how much money they have. Instead, they care about their relationships（关系）with friends, teachers and parents. “Students always feel better when they get along well with each other,”Li said.After her survey, Li listed a number of tips that may make students happier, such as: Treat(对待) yourself better, be kind and polite to your friends and relatives, and try new things.AOn January 26th, the biggest earthquake (地震) in India took the lives of 25, 000 people. In the morning, when everybody was enjoying holiday, earthquake began. It was about 7. 5 on the Ritcher scale. “There is nothing left between the sky and the earth any more. Everything has been pulled down,” said one of the villagers alive. “There is no water, no food and no one has come to help.”Nobody died in Pakistan, a country next to India. The City of Lahore was lucky. In Lahore American School, where I was studying, all of the students were safe. They were in the field, so most children didn’t feel anything. The earthquake was felt by the teachers that were on the second floor. However, though Mrs. Young was also on the second floor, she didn't feel anything. She didn’t know what happened until a teacher told her about it. Those teachers who were on the other floors had different feelings. Mr. Emond, the maths teacher from Australia, said that when the earthquake started he thought there was something wrong with him, but then another teacher said that it was an earthquake. After those words Mr. Emond felt better. Mrs. Davis and Mr. Frost didn’t feel anything, either.My moth er didn’t feel anything. She didn’t even know that it was an earthquake till she saw a shaking (moving from side to side) light. My dad saw the computer shaking and then he looked out of the window and saw many people going out.BHead teacher, teachers, grandparents, parents and classmates, I’m very proud that I have been chosen to speak to you all today. I’m a bit nervous as I’ve never made a speech before to so many people, so please forgive me if it shows! www.As we all know, this is the school l eavers’ party, and it’s time to say goodbye to everyone. We’re sorry to leave you at the end of our junior high school education, and we promise that we'll never forget the happy times we have spent in these buildings with you all.I’d like to thank three groups of people for the three things I’ve learnt while I’ve been a pupilat our school. The three things are friendship, love and knowledge.The first group is my friends, and what I’ve learnt is the importance of friendship. We’ve worked hard tog ether, we’ve even shared some difficult times together, but we’ve also had a lot of fun. Many of us will go to new schools and we may not see each other so often in the future. Others will go on to senior high school and continue their close friendships. B ut friends don’t have to see each other all the time. Sometimes the friends you treasure most are the friends you see less often. A life without old friends is like a day without sunshine. We'll always stay in touch.The second group is our parents and grandparents. We thank you for the love you have shown us during our years at junior high school, for making a home where we feel both safe and relaxed, and where we can prepare ourselves for our school days. We also thank you for your help with our homework. How many of us owe our good grades to the suggestions you have made during those long evenings?And finally, the third group is our teachers. We can never pay you back for your kindness, your patience, and gift of knowledge which you have offered us; sometimes you’ve made us w ork very hard. But you have always been fair and you’ll always be our role models. There’s a saying from Ireland which is a favourite of mine: Strangers are only friends you haven’t met yet.I couldn’t say it better myself. So from the bottom of my heart, I thank you all and wish you success for the future.CNo one wants to look silly or do the wrong thing at a new job. It is important to make the right impression（印象）from the very first day. You will face new people. You will be in a new place. It may be difficult to know what to do. Here are five tips to help you make it through the first day ina new job:①First impression can last forever. Make sure you make a good one. Before your first day, find out if your new job has a dress code (rules about what you can wear to work). If so, be sure to follow it. No matter what, always be neat and clean.②Get to work on time . Give yourself an extra 15 minutes to make sure you arrive on time.③Pay attention to introductions. You may be introduced to your workmates. They will be important to you. They are the ones who will answer your questions when the boss is not around.④Ask plenty of questions. Make sure that your supervisor has told you what is expected of you. If you are not told your duties, ask for a list. Set daily and weekly goals for yourself.⑤Never be the first one to leave. Watch what others do at the end of work hours. It does not look good for you to be eager(急切的) to leave.66. If the red light doesn’t come on, wait for thirty seconds.67. She wanted to show off her new clothes at the party.68. A coach should act as a role model for his athletes.69. He broke the window and ran away.70.Weight lifting is best way to increase the bone density.Jack: Hi, Kate, What are you going to do this weekend?Kate: I’m going to Wuhan.Jack: Wuhan? Why are you going to WuhanKate: Because there is going to be a match between China and Russia.Jack: How wonderful!Kate: Would you like to go with me?Jack: I’d like to very m uch. What kind of match is itKate: It’s a volleyball match.Jack: _ Where will it be heldKate: It will be held in Wuhan Gym.Jack: By the way, How shall we go thereKate: Le t’s take the bus there tomorrow, shall we?Jack: All right. Good-bye!Kate: Good-bye!Long ago, people did not need money. They lived on wild animals, fruits and other plants.As time passed, people learned to raise animals and crops. Sometimes, families produced more than they needed, so they started to trade with other families. 78 Later, people began to use money as a means of exchange. However, it was not the kind of money we use today. They used shells, rice, salt, large stones, etc.During the 600s B.C, people began using coins as money. They soon found that coins were easier to carry than goods and lasted a long time. Later, countries began to make their own coins.The Chinese were the first to use paper money, probably as early as the 11th century. The Italian traveler Marco Polo saw the Chinese using money when he visited China in the 1200s. 79 However, European countries did not start using paper money until 1600s.Today, we have many ways to pay for things. We do not use coins or paper money. Often, people prefer to pay for things by card. Paying with a card is easier and safer than carrying around a lot of “real” money.In many big cities in the world, the overuse of cars is thought to be one of the major causes of air pollution. What will cars be like in the future?Some experts think that today’s cars are in trouble because they use too much petrol( 汽油). They say the car of the future will be much, much smaller. The car of tomorrow will be made without a motor or air conditioning. It’ll have no radi o and no lights. Tomorrow’s car will be an open air car with no doors or windows. It needn’t have a pollution control system because it won't use petrol. In fact, this new car will be pushed by the driv er’s feet. Very few people will be killed in accidents, because the top speed will be five miles per hour. However, we are also warned not to ask for pretty colours, because the cars will come in grey only.Other car experts do not hold the same idea. They are sure that the future will be happier. They think that all our problems will soon be solved by car companies with the production of the Supercar. Tomorrow’s car will be bigger, faster, and more comfortable than before. The Supercar will have four rooms, TVs, running water, heat, air conditioning, and maybe a swimming pool. Large families will travel on 1ong trips comfortably. If petrol is in short supply (供给) , the Supercar will run on water.。
