A21. What’s worrying Anna?A. Her friend keeps telling lies.B. Her friend is not interesting.C. Her friend does not believe her.D. Her friend reads her terrible stories.22. Dani suggests that Tom _____.A. leave his two friendsB. tell his friends his thoughtsC. go on an outing with one of his friendsD. invite another to join his group of friends23. Whose friend has a big mouth?A. Tom.B. Mary.C. Anna.D. Daisy.24. The underlined word “teasing” in the last paragraph probably means “_____”.A. avoidingB. hatingC. making fun ofD. taking pity onBOn my first day of high school, I asked an eleventh-grader where my class was. And he told me it was “on the fourth floor, next to the pool.” I found out five minutes later th at we don’t even have a fourth floor and there’s no pool either! Besides that, I didn’t have any trouble with the older kid.I think the biggest difference between middle and high school is the homework load (工作量) and size of the school. I went from maybe fifteen minutes of homework a night to several hours, so I had to learn how to make full use of time! Our class size is around 550, but joining in clubs, sports, music, and other activities at school makes it easier to get to know people in every grade.The best advice I can give about the years you spend in high school is to learn things for yourself, not just to get a good grade. There have been so many tests that I’ve prepared for the night before, gotten an A, and not remembered anything later. I’ve changed that this year, and I enjoy school so much more. Don’t take easy classes just to have a simple year. If you have a choice between chemistry and sports, the first will prove to be a lot more useful!While drinking and smoking might be present i n some middle schools, they’re also around in high school. I have a lot of friends who promised they’d never drink or smoke, but are now partying every weekend. If you have “fun” and spend your nights wasted instead of studying, you will regret it when you’re applying for (申请) college. The “friends” who say you’re a loser for not partying are really not your friends at all. It’s hard to see your closest friends grow apart and go in different directions, but don’t follow their footsteps. Create your own path in life and make your own decisions.25. What happened to the author on his first day of high school?A. He had a fight with an eleventh-grader.B. He fell into a pool on the fourth floor.C. He was five minutes late for class.D. He was fooled by a schoolboy.26. The author advises high school students to _____.A. give up sportsB. choose useful classesC. try their best to get good gradesD. get ready for tests the night before27. The last paragraph mainly tells us _____.A. about the trouble caused by drinking and smokingB. about the importance of making friendsC. not to go to any party in high schoolD. not to lose ourselves in high schoolCIn the book The Best Little Girl in the World, Kessa has a serious eating disorder (进食障碍) called anorexia nervosa. But she is not alone. Many people have this eating disorder.In the beginning of her story, Kessa is a normal 15-year-old. She is good at many things, especially dancing. She has danced for many years and loves it. One day her dance teacher tells her to continue eating right, but maybe lose a few pounds. Once Kessa hears this, she takes things too far. Instead of cutting down on snacks and junk food, she decides not to eat at all. She does not eat breakfast, lunch, or dinner. She begins losing weight and becomes slimmer (更加苗条的) and slimmer. But she loses weight to a point where she is unhealthy.As her poor eating habits continue, her parents start getting as much help as possible to cure (治疗) their beautiful daughter. But it is just as hard for Kess a’s parents to deal with her disorder as it is for her. Everyday she exercises to lose more pounds and plans what and when she will eat. Her parents try everything, but Kessa decides not to have any fat on her body.Kessa’s doctor and parents finally take her to the hospital. She is now so thin that she can hardly walk. There, she is given good care.In the rest of the book, Kessa goes through a lot of trouble in order to cure her eating disorder. This book, I think, can help to prevent people from doing this to themselves. It shows the trouble that people go through just to be slimmer, and all theterrible things they must experience to be cured. It is a book I think every teenager should read.28. What does Kessa do to lose weight?A. She stops eating.B. She eats less junk food.C. She has three small meals a day.D. She dances many more hours a day.29. What do we know about Kessa’s eating disorder?A. It is caused by her dance teacher.B. It’s too serious to be cured.C. It makes her suffer a lot.D. It’s an unusual illness.30. The book mentioned in the text is mainly about _____.A. how to cure eating disordersB. the importance of eating rightC. a girl’s fight against an eating problemD. why so many people have eating disordersDTime for Kids (TFK) gets the great news on the coolest toys for 2014 at the 111th American International Toy Fair.What’s four days long, bigger than seven football fields, and filled with thousands of toys? It’s Toy Fair 2014!Each year, hundreds of toy companies from across the country come together in New York City. All kinds of products are shown as a way to know what’s to come in the new year.

More than 1,000 toy companies showed products from simple card games to high-tech robots. “Larger Than Life” was a Toy Fair favorite. This trend is all about big toys with a big play value.Though it is all fun and games at Toy Fair, we saw lots of products making a push towards education, with STEAM. That stands for science, technology, engineering, art, and math. This trend includes word games. And of course, we saw some super cool, high-tech games. “Technology is always going to influence toys,” says Appell. “This year we saw lots of 3D games, and robots.”To know more information about the event, click (点击) here to watch the video.31.

He stayed there for several months and then came home again. Some of his friends visited him a few days after he got back. “I had a very dangerous trip while I was in Russia, ”Jack said to them. “I wanted to see a friend of mine in the country and the bad weathermade me very late. So I was still traveling through a forest in a sleigh(雪橇)when the sun went down. It was a long way from my friend’s house when about twenty wolves began to follow my sleigh. It was very dark in the forest. There was thick snow on the ground. It was cold, and there were no houses for miles and miles. First, I heard the wolves. The noise was terrible! The horses heard them, too. They were frightened and began running faster. Then, I saw long, gray forms among the trees, and soon the wolves were near us. They were running very fast, and they didn’t seem to get tired like the horses. ”“What did you do? ”one of Jack’s friends asked.“When the wolves got very near, ”Jack answered, “I put up my gun and shot the first wolf. The sleigh was moving about, but I hit the animal and killed it. Then all the other wolves stopped and ate it, so our sleigh got away from them for a few minutes. ”“Then they finished their meal, and I heard them coming again. The moon was shining brightly on the snow now, and after a few minutes, I saw them running among the trees once more. They came nearer again, and then I shot another of them, and the others stopped once more to eat it. ”“The same thing happened again and again, and my horses became more and more tired and ran slower and slower until after about two hours, only one wolf was still alive and following us. ”“Wasn’t it too fat to run? ”one of his friends asked.1. Jack told his friends what happened to him when he was ______________.A. in England one winter eveningB. in Russia one winter eveningC. in America one winter morningD. in Russia one winter morning2. The underlined word “meal”in the fourth paragraph here means ______________.A. the food Jack had brought with himB. the meal prepared by Jack’s friendC. the wolf which had been killed by JackD. the dead animals on the way3. According to what Jack said, the last wolf ______________.A. had eaten more than one wolfB. was the strongest of allC. ran much faster than the other wolvesD. was very fat and didn’t run fast enough4. From what Jack’s friend said in the last paragraph, we know that ______________.A. all the wolves had been shot by JackB. the last wolf was too fat to runC. Jack was telling the truthD. the friend did not believe what Jack had saidBSome British and American people like to invite friends for a meal at home. You should not be upset(不安的)if your English friends don’t invite you home. It doesn’t mean they don’t like you! Dinner parties usually start between 7 p. m. and 8 p. m. , and end at about 11 p. m. . Ask your host(主人)what time you should arrive. It’s polite to bring flowers, chocolates or a bottle of wine as a gift.Usually the evening starts with drinks and snacks(小吃). Do you want to be extra(特别地)polite? Say how much you like the room, or the pictures on the wall. But remember-it’s not polite to ask how much things cost.In many families, the husband sits at one end of the table and the wife sits at the other side. They eat with their guests.You’ll probably start the meal with soup or something small, then you’ll have meat or fish with vegetables, and then dessert(甜点心)followed by coffee. It’s polite to finish everything on your plate and to take more if you want it.Did you enjoy the evening? Call your hosts the next day, or write them a short “Thank you”letter. British and American people like to say “thank you”all the time!5. An English friend doesn’t invite you to his or her dinner, which ______.A. means he or she doesn’t like youB. means he or she likes youC. doesn’t mean he or she likes youD. doesn’t mean he or she doesn’t like you6. You are going to attend a dinner party and ______________.A. you’d better bring a certain present with youB. you must leave home for it at 7 p. m.C. you should ask your host when you should leaveD. you must arrive before 8 p. m.7. In which order will you eat or drink the following things at a meal?()A. Snacks, vegetables, meat, coffee.B. Coffee, drinks, soup, fish, vegetables, dessert.C. Soup, meat or fish with vegetables, dessert and coffee.D. Drinks, soup, something small, fish and vegetables.8. What is the proper way to express your enjoyment of the evening?()A. Before leaving for home, you should say, “Thank you for inviting me. ”B. When you shake hands with your host, you should say, “I did enjoy the evening. ”C. You can write a “Thank you”letter to your host after that.D. You should finish everything on your plate and take more if you want itC“Do you like my dress? ”she asked a stranger. “My mum made it just for me, ”she said with tears in her eyes. “Well, I think it’s very pretty, so tell me, little girl, why are you crying? ”The little girl answered in a low voice, “After mum made me this dress, she went away. My dad says that she’s up in heaven(天堂)now with Grandfather. ”Finally,the woman realized why she was crying. She felt very sorry for the little girl and gently held the child in her arms. Then suddenly the little girl did something a bit strange. She stopped crying, walked back from the woman and began to sing. She sang softly. It was the sweetest sound the woman had ever heard, almost likethe song of a very small bird.After the child stopped singing, she said to the lady, “My mum often sang that song to me before she went away, and she asked me to sing it whenever I started crying and it would make me stop. ”“See, ”she said loudly, “it did, and now my eyes are dry! ”Just before the lady wanted to go, the girl showed her a spot(印迹)on her dress, and said, “Right here is where my mum kissed my dress, and here, ”pointing toanother spot, “and here is another kiss, and here, and here. Mum said that she put all those kisses on my dress so that I would forget my sadness. ”Then the lady realized that she wasn’t just looking at a dress, no, she was looking at a mother. The mother knew that she was going away and would not be there to kiss away her daughter’s hurts any longer. So the mother gave all her love to her beautiful daughter and put it into this dress. Now her child was wearing it so proudly(骄傲地).The lady no longer saw a little girl wearing a simple dress. She saw a child wrapped(包)in her mother’s love.9.
