ADoctor Seuss was born in 1904. By the middle 1950s, he had become one of the best-loved and most successful children's book writers in the world . His books are very popular with young readers. They enjoy t he invented words and the pictures of unusual funny animals and plants.In 1954, life magazine published a report about school childre n who could not read. The report said many children's books were not interesting. Doctor Seuss strongly hoped to help chil dren and decided to write books that were interesting and eas y to read. He used words with the same ending sound, like fis h and wish. He did not receive training in art. Yet, he drew thepictures for most of his books.In 1957, Dr. Seuss wrote The Cat in the Hat. He used less tha n 230 words to write the book and even a six-year-old should be able to read it. It was a fun story and easy to re ad. Children loved it. Their parents loved it, too. Today it is stil l one of the stories they like best. The success of The Cat in t he Hat made him want to write more books for children. In 19 60, he wrote a book using less than fifty words. The book is c alled Green Eggs and Ham.In 1984, Doctor Seuss won a Pulitzer Prize (普利策奖). He was honored for the education and enjoyment his boo ks provided American children and their parents.He died at the age of 87, but his influence remains. Millions of his books have been sold worldwide. People say his books h elped change the way American children learned to read. Yet, his books are loved by people of all ages. Doctor Seuss once said, "I do not write for children. I write for people.1. People like Seuss’ books because the books ______.A. are cheap and easy to getB. were written in different languagesC. are easy and interesting to readD. were written with invented words2. He wrote the book The Cat in the Hat at the age of _____.A. 50B. 53C. 56D. 873. Which of the following is TRUE according to the passage?A.

His books provided education and enjoyment for American s.4. From the text we know that Doctor Seuss __________.A. won a Pulitzer Prize soon after his deathB. sold millions of his books himself worldwideC. changed American children's way of readingD. wrote the largest number of books in the worldBHappiness is important for everyone. Most people want to be happy but few know how to find happiness. Money and succe ss don’t bring lasting happiness. Happiness depends on ours elves. In other words, we make our own happiness.Some people believe that if they are wealthy, they will be able to do anything they want, which means happiness. On the ot her hand, some people believe that holding a high position in t he government is happiness. In this way, you have not only m oney, but also many other things which can’t be bought by mo ney. However, other people believe that having lots of money is not happiness, nor is holding a high position in the governm ent. These people value their beliefs, or their intelligence, or t heir health. They think these can make them happy.Here are a few ways to help you be happier.The first secret of happiness is to enjoy the simple things in lif e. Too often, we spend so much time thinking about the future , for example, getting into college or getting a good job, that w e don’t enjoy the present. You should enjoy life’s simple pleas ures, such as reading a good book, listening to your favorite music, or spending time with close friends. People who have close friends usually enjoy happier and healthier lives.The second secret of happiness is to be active. Many people go dancing or play sports. People can forget about their probl ems and only think about the activities.Finally, many people find happiness in helping others. Accordi ng to studies, people feel good when they volunteer their time to do many meaningful things for other people. If you want tofeel happier, do something nice for someone. You can help a friend with his or her studies, go shopping to get food for an ol d neighbor, or simply help around the house.Now maybe you know how to find happiness!5. The underlined word “wealthy” means “__________” in the a rticle.A. pleasedB. healthyC. excitedD. rich6. The writer thinks the secret of happiness is that people ___ ________.A. think about getting a good jobB. think of presents th ey don’t likeC. often spend time with close friendsD. often spend time on entering the college7. The passage mainly tells us _________.A. how to find happinessB. how to save happines sC. to do something good for othersD. to value our belie fs or healthCWelcome to your future life!You get up in the morning and look into the mirror. Your face i s firm and young-looking. In 2035, medical technology is better than ever. Many people at your age could live to be 150, so at 40, you’re not o ld at all. And your parents just had an anti-aging treatment. Now, all three of you look the same age! You say to your shirt, “T urn red.” It changes from blue to red. I n 2035, “smart clothes” contain particles much smaller than th e cells in your body. The particles can be programmed to cha nge your clothes’ color or pattern.You walk into the kitchen. You pick up the milk, but a voice sa ys, “You shouldn’t drink that!” Your fridge has read the chip th at contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has suc h a chip.It’s time to go to work. In 2025, cars drive themselves. Just tel l your “smart car” where to go. On the way, you can call a frie nd using your jacket sleeve. Such “smart technology” is all aro und you.So will all these things come true? “For new technology to suc ceed,” says scientist Andrew Zolli, “it has to be so much better that it replaces what we have already.” The Internet is one ex ample—what will be the next?8. We can learn from the text that in the future ________.A. people will never get oldB. everyone will look the sameC. red will be the most popular colorD. clothes will be able to change their pattern9. What can be inferred from Paragraph 4?A. Milk will be harmful to health.B. More drinks will be available for sale.C. Food in the grocery store will carry electronic information.D. Milk in the grocery store will stay fresh much longer.10. Which of the following is mentioned in the text?A. Nothing can replace the Internet.B. Fridges will know what people need.C. Jacket sleeves can be used as a guide.D. Cars will be able to drive automatically.11. What is the text mainly about?A. Food and clothing in 2035.B. Future technology in everyday life.C. Medical treatments of the future.D. The reason for the success of new technology.DFirst aid is emergency care for a victim of sudden illness orinjury until more skillful medical treatment is available. It may save a life or improve certain important signs including pulse, temperature, a clear airway, and breathing. In minor emergen cies, first aid may prevent a victim's condition from turning wor se and provide relief from pain. First aid must be done as quic kly as possible. In the case of the seriously injured, a few min utes can make the difference between complete recovery and loss of life.First-aid measures depend upon a victim's needs and the provider' s level of knowledge and skill. Knowing what not to do in an e mergency is as important as knowing what to do. Improperly moving a person with a neck injury, for example, can lead to p ermanent spinal(脊柱的) injury and paralysis (瘫痪) .Despite the variety of injuries possible, several rules of first aid apply to all emergencies. The first step is to call for expert medical help. The victim, if conscious, should be reassured t hat medical aid has been requested, and asked for permissio n to provide any first aid. Next, assess the scene, asking oth er people or the injured person's family or friends about detail s of the injury or illness, any care that may have already been given, and pre-existing conditions such as diabetes(糖尿病) or heart trouble. The victim should be checked for a medical card that describes special conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury, do not move the victim.First aid requires rapid assessment of victims to decide wh ether life-threatening conditions exist. One method for accessing a victi m's condition is known by the acronym(首字母缩写词) ABC, which stands for:A-Airway: Is it open and clear?B-Breathing: Is the person breathing? Look, listen, and feel for b reathing.C-Circulation: Is there a pulse? Is the person bleeding externally ? Check skin color and temperature for additional indications of circulation problems.12. First aid may bring about all the following results EXCEPT .A. saving a victim's lifeB. preventing a victim's condition from getting worseC. relieving a victim from painD. helping a person avoid sudden illness or injury13. Before we offer first aid to a victim, it is very important for us .A. to make sure what to do and what not to doB. to refer to all kinds of handbooks on first aidC. to remove the ring or bracelet he/she may be wearingD. to take him/her to a hospital at once14. In giving first aid to a victim, you should first of all .A. remove his/her from the accident sceneB. turn him/her overC. call for professional medical helpD. examine him/her carefully15. The purpose of the passage is to tell the reader . .A. the importance of protecting the accident sceneB. some basic facts about first aidC. what professional medical help isD. who can offer first aid第二节 (共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。
