AJack is the name of a game. It is quite popular with children. To play jacks, you will need a small ball and ten small metal objects (物体) called jacks.The rules for this game are quite easy. To begin with, put the ten jacks on the floor or ground in front of you. Toss the ball high, pick up one jack and then catch the ball. Keep the jack in your hand and go on to pick up the other jack one at a time. You lose your turn if you do not catch the ball, or if you do not pick up a jack, or if you drop (掉) any of the jacks from your hand.When you finish all the ten jacks, you now try to do the same thing again but with two jacks at one time. This is more difficult, of course. You lose your turn if you make any of the above three mistakes (错误) or if you do not pick up two jacks each time.16.To play jacks is ___________.A. difficult for boysB. interesting for childrenC. difficult for girlsD. interesting for old people17.The word “toss” here means __________.A. dropB. catchC. throwD. pick18.If you want to finish the first and second parts of the game, you have to pick up jacks __________.A. ten timesB. fifteen timesC. twenty timesD. thirty times19.The jacks are made of _________.A. paperB. glassC. metalD. water20.After you pick up the first ten jacks, the game becomes more difficult because you must pick up _________ at a time.A. two jacksB. four jacksC. three jacksD. only oneBThere are many different kinds of disasters around the world. As an adult you know what to do during a disaster, but what about the children? Some adults think it would probably never happen to them, so they don’t teach their children what to do. Before it’s too late, here are ways to help you prepare your child for a disaster:Educate: It is always good to let your child know about possible disasters. This doesn’t mean children have to live in fear. When teaching them about disasters, keep the conversation positive(积极的)by telling them there is a solution(解决办法)to the disaster. Keep the conversations short, allow for questions and answer honestly.Prepare: Always be prepared, that is the best advice for children. For example, when preparing for bad weather, get the tools you need, like candles, radios, food, water and medicine. Teach your child what is needed in certain disasters so that they know what is available for them, if ever needed.Plan: You should always have a plan for you and your child for any dangerous situation. Write out a simple list that they can read. The plan could start with “listen to an adult’s advice and/or call 119”.Practice: Once you have got the correct safety tools and worked out the right plan, practice every few months. Practicing what to do during a disaster with your child will help them if the time comes.Disasters can’t be avoided but they can be lessened(减轻)once you are prepared and ready for one.21. What does the word ‘disaster’ mean?A. 命运B. 灾难C. 演习D. 倾销22. What should adults teach children?A. When disasters will happen.B. Why disasters are dangerous.C. What to do for a disaster.D. How to avoid a disaster.23. What is the correct thing to do for adults?A. Have positive conversations with children.B. Try not to talk about disasters with children.C. Make the children scared of disasters.D. Ask children lots of questions.24. What’s the most important thing for children?A. Always ask adults for help.B. Always be prepared for a disaster.C. Always listen to an adult’s advice.D. Always remember where the tools are.25. What is NOT suggested doing?A. Remembering what is needed in certain disasters.B. Getting the children to know the plan well.C. Helping people in disaster areas.D. Getting radios for bad weather.CNowadays, cell phones are part of our lives. Many people have cell phones. They can help us easily find people anywhere at any time. However, using cell phones too often may cause cancer(癌症). It’s reported that people who use a cell phone for 10 years or more may get brain cancer.The suggestions below may help you reduce(减少) the risk of cancer:When using your cell phone, try to keep it away from your body as much as possible. Don’t put it on the bedside table when you go to sleep.When you’re on the cell phone, use the speaker(扬声器). In this way, you have just 1/100th of the contact(接触) with radiation you have when you hold it to your ear. An earphone is also a good idea.Try to keep your conversations short. If you need to talk longer, use an ordinary phone instead.Change ears when you’re using your cell phone. Before putting it to your ear, wait until the person you are calling picks up the phone.Your phone gives out radiation when you talk or send messages, but not when you’re listening or getting messages. Listening more and talking less can lower the risk of cancer.Do not use your cell phone when the signal(信号) is weak or when moving at a high speed, for example in a car or on a train. At high speeds your phone is trying to pick up signals, and this increases the radiation it gives out.26. According to the text, using cell phones too much may cause ___________.A. toothacheB. cancerC. heart diseaseD.stomachache27. The underlined word “radiation” in Paragraph 4 probably means “______” in Chinese.A. 辐射B. 电池C. 网络D. 手机28. You’d better______________.A. use your cell phone when the signal is weakB. use your cell phone on a high-speed trainC. change ears when you’re using your cell phoneD. never use your cell phones.29. Which of the following is TRUE according to the textA. Using an earphone is a good way to reduce the radiation.B. You can put your cell phone on the bedside table when you go to sleep.C. Listening less and talking more can lower the risk of cancer.D. Using an earphone is a bad way to reduce the radiation.30. The purpose of the text is to tell us how to properly ____________.A. buy a cell phoneB. use a cell phoneC. repair a cell phoneD. sell a cell phoneDWhat should we do if one of our classmates suddenly falls ill or gets hurt?Here are some steps you should follow.But always remember to look for medical care after first aid(急救)if the wound is serious.Broken bones(骨头):Take away clothing from the wound.Use an ice pack.Don't move the hurt body part while waiting for the doctor to arrive.Animal bites(咬伤):Wash the bite area with soap and water.Pack the wound with a clean cloth if it is bleeding.If the bleeding has stopped,cover the area with a bandage and take the person to the hospital.Make sure you remember what kind of animal it is so the doctor can find the right way to treat him or her at once.Fainting(昏厥):Have him or her lie with feet lifted a little.Don't move the body if you think there might be wounds from the fall.Make sure he or she can breathe and let in fresh air.Clean the person's face with a cool cloth.Nosebleeds:Have the person sit up with his or her head tilted(倾斜)forward a little.Do not have the person tilt his or her head back because this may cause heavy breathing or coughing.Pinch(捏) the lower part of the nose for atleast 10minutes.31.What should we do first when an animal bite happens?A.Put an ice pack on the wound.B.Wash the bite area with soap and water.C.Try to stop the bleeding with a clean cloth.D.Take the hurt person to the hospital.32.When dealing with the problems of _______,we shouldn't move the hurt.A.broken bones and animal bites B.animal bites and nosebleedsC.broken bones and fainting D.fainting and nosebleeds33.Which of the following is not right when a boy's nose bleeds?A.Let his head not tilt back. B.Let his head tilt forward a little.C.Let him sit up. D.Pinch his nose for less than10minutes.34.Which part of a magazine may the passage come from?A.Lifestyle.B.Health. C.Sports. D.Education.35.What's the main idea of the passage?A.First aid for some accidental wounds.B.Steps of looking for medical care.C.Advice on ways not to get hurt. D.Ways to ask for help in getting hurt.第二节(共 5 小题,每小题 2 分,满分 10 分)请根据的小标题,从下面的描述中找出与其相匹配的选项。
