Think before you decideCAbout 230 years ago, some rats got to Hawadax Island and they killed the birds on the island. Now thanks to five-year hard work by volunteers, the silent Rat Island as it had been called for many years, has been returned to its rightful owners — birds.The rats arrived at Hawadax Island in 1780 when a Japanese ship carrying them broke down at sea nearby. They completely killed the native animals because the environment of the island was not built to save its animals from the rats. There are no trees on the island, which meant that the birds were used to building their homes low in the ground, giving the rats chance to eat both eggs and baby chicks. As years passed, the birds that had called the island home for thousands of years, disappeared completely.In 2007, the U.S. Fish and Wildlife Service started an action to drive the rats away from the island and try to bring back the beautiful birds that had once called it home. Because there were about 10,000 rats living on the Rat Island, so it was not an easy task. But by 2009, there were no more rats on the island!Then slowly but surely, the birds began to return. Sadly, some of the birds were killed by the rat poison that had been used to deal with the rats. But now it seems things are becoming better and the island is starting to look like its old self.Today, the sounds of singing birds flying in and out are a common sight. Volunteers have found more and more ground homes and birds on the island. Though the island is still not back to its nature, it’s now getting better and better.40. Who killed the birds in Hawadax Island 230 years ago?A. ratsB. huntersC. volunteersD. Japanese41. What does the underlined words “rat poison” in Paragraph 4 mean?A. Something that a rat makesB. Something that a rat likesC. Something that helps a ratD. Something that kills a rat42. The writer wants to tell us that ______?A. the island is now back to its natureB. rats will soon come back to the islandC. no birds want to come back to the islandD. more and more birds will come to the island六、五选五。

I’d been dreaming of an Olympic gold medal since I was eight-but gradually, that dream seemed like a million miles away.On January 2,2012, while Mon was visiting me in Iowa, I told her, “I don’t l ike gymnastics anymore, I want to try dancing, or become a singer, I can get a job in Virginia, I just want to come home.”Mom’s eyes narrowed and her expression turned to stone. “You’re breaking my heart, Brie,” she said. “You’ve been doing gymnastics for ten years, and now you want to quit ? Have you lost your mind?”I hadn’t lost my mind, but I had lost my fire. It’s an entirely different thing to push toward that dream when you feel alone.“I’m not trying to break your heart, Mom,” I said. “I just don’t want to do it anymore.”“I know you miss home.

Max sails back home and his supper is still hot when he arrives in his bedroom.Many teachers and professors like this story and use it to help children develop creativity and imagination. Melina Davis, an education professor, said she likes how the book contains a couple of pages tha t have only pictures on them, “This allows children to shape the story themselves,” she said.The book contains a few of larger words that some parents worry may confuse children, but experts say those words help improve children’s reading skills and chall enge them.Davis said the book is well written which helps kids get involved-in the story. “The book talks about what all children go through, like ‘ I was naughty but my mommy still loves me’,” Davis said.The book also encourages children to face their fears. “I think it’s really good to show that Max is friends with the monsters, ” Davis said. “ Kids can find out monsters aren’t always the thing under the bed that’s going to scare them.

In Panama City Beach, Florida, a city with a population of around 36,000, mouse than half a million university students arrive during the month of March to play and party, making it the number one spring break destination in the US.A weeklong drinking binge is not for everyone, however, and a growing number of American university students have found a way to travel locally or internationally and work for problems such as poverty, homelessness, or environmental damage makes spring break a unique learning experience that university students can feel book about.During one spring break week, students at James Madison University in Virginia participated in 15 “ alternative spring break ” trips to nearby states, three others to more distant parts of the United States, and five international trips. One group of JMU students traveled to Bogalusa, Louisiana, to help rebuild homes damaged by hurricane. Another group traveled to Mississippi to organize creative activities for children living in a homeless shelter.Students who participate in alternative spring break projects find them very rewarding. Students often sleep on the floor of a school or church, or spend the week camping in tents. But students only pay around ＄250 for meals and transportation, which is much less than some of their peers spend to travel to more traditional spring break destination.Alternative spring break trips appear to be growing in popularity at universities across the US. Students mention a number of reasons for participating. Some appreciate the opportunity to socialize and meet new friends. Others want to exercise their beliefs about people’s obligation to serve humanity and make the world a better place. Whatever their reasons, these students have discovered something that gives them rich rewards along with a break from school work.66.

University students do different types of work on alternative spring break trips69. Which of the following is mentioned as a reason for participating in alternative spring break trips ?A. A hope of earning more moneyB. A desire to travel to distant places.C. An opinion that people must help others.D. A wish to get away from family and friends.70. The text is mainly about ______.A. alternative spring break tripsB. spring break in Florida and MexicoC. sleeping on the floor or camping in tentsD. famous tourist destinations around the USDPeople have always been dreaming of going to the moon. As long ago as the year 1901, H. G. Wells, an English writer, wrote a book vividly describing a trip to the moon. On landing there, the explorers discovered that the moon was full of underground cities. Words failed to express their surprise when they spotted so many “ moon people ”. The “ moon people ” felt even more surprised “ Why, ” they asked, “ are you traveling to outer space when you don’t even use your inner space ?”H. G. Wells could only imagine a travel to the moon. In 1969, human beings really left their footsteps on the moon, People today know that there are no underground cities on the moon. However, the qu estion that the “ moon people ” asked is still an interesting one. A growing number of scientists are seriously thinking about it.Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The “ Channel ”, a tunnel connecting England and France, is now complete.But what about underground cities ? Japan’s Taisei Corporation is designing a network of underground systems, called “Alice Cities ”.The designers imagine using surface space for public parks and using underground space for flats, offices. shopping, and so on. A solar dome （穹顶）would cover the whole city.Supporters of underground development argue that building down rather than building up is a good way to use the earth’s space. The space. they say, can be used for farms, parks, gardens, and wilderness. H. G. Wells’ “ moon people ” would second it Would you ?71. The explorers in H. G. Well’s story were surprised to find that the “ moon people ” ______.A. lived in underground citiesB. understood their languageC. knew so much about the earthD. were advanced in technology.72. What does the underlined word “ it ” ( paragraph 2) refer to ?A. Discovering the moon’s inner s paceB. Using the earth’s inner spaceC. Meeting the “ moon people ” againD. Traveling to outer space.73. What sort of underground systems are already in place?A. Tunnels, gardens, offices.B. Tunnels, car parks. shopping areas.C. Gardens, car parks, power stations.D. Offices shopping areas, power stations.74. We can learn from the text that ______.A. H. G. Wells once went to moon himself.B. underground cities are more comfortable.C. more underground systems would be in place in 2013.D. the solar dome is a necessary part of underground cities.75. What would be the best title for the text ?A. Enjoy livingB. Building down, not upC. Alice Cities—cities of the futureD. Space travel with H. G.

They weigh only about eighty pounds each.In spite of their small size, they are the best hunters among all the jungle people. Even the great elephant can be caught by them.Since they do not plant any crops, Pygmies are constantly moving around. They seldom sleep in one camp for more than a few days. In their camps there is not furniture at all except for some weapons such as spears, bows and arrows. There are no cooking pots either. Food is eaten uncooked or smoked over a lire. So when the tribe moves to a new camp there is nothing to carry except these weapons and babies too small to walk.Pymies can move on the tree tops almost as skillfully as monkeys. Often they travel great distances through the branches without touching the ground.One of the surprising facts about these small men and women is their great appetite（食欲）. A Pygmy can eat up sixty bananas at a single meal besides quantities of meat. After eating, they will lie on their hard earth bed and groan（呻吟）in all night. But in the morning, they are ready to eat the same amount of food or fight among themselves.51．Pygmies are small in size, but they are brave in ______.A．hunting B．shooting C．eating D．fighting with their enemies 52．Pygmies are so skillful that _____.A．they never walk on the ground B．they can move on the top of treesC．they always walk with sticks D．they can hang from the branches53．The writer wrote this article so as to ______A．ask people to learn from Pygmies B．help Pygmies go out of the forestsC．let us know the local condition and customs of the PygmiesD．tell us the world is big and wide54．Why do Pygmies move from place to place continuously? The main reason is that _____.A．that want to look after wild animals B．they always walk with sticksC．they plant no crops D．they don’t sleep in one campBThis is a great truth, one of the greatest truths.It is a great truth because once we truly see this truth, we transcend（超越）it. Once we truly know that life is difficult---once we truly understand and accept it---then life is no longer difficult. Because once it is accepted, the fact that life is difficult no longer matters.Most do not fully see this truth. Instead they complain about their problems and difficulties as if life should be easy. It seems to them that difficulties represent a special kind of suffering especially forced upon them or else upon their families, their class, or even their nation.What makes life difficult is that the process of facing and solving problems is a painful one. Problems, depending on their nature, cause us sadness, or loneliness or regret or anger or fear. These are uncomfortable feelings, often as painful as any kind of physical pain. And since life causes an endless series of problems, life is always difficult and is full of pain as well as joy.Yet, it is in this whole process of solving problems that life has its meaning. Problems are the serious test that tells us success from failure. When we desire to encourage the growth of human spirit, we encourage the human ability to solve problems, just as in school we set problems for our children to solve. It is through the pain of meeting and working out problems that we learn. As Benjamin Franklin said, those things that hurt, instruct. It is for this reason that wise people learn not to fear but to welcome the pain of problems.55. From the passage, it can be inferred that ______.A. everybody has problemsB. we become stronger by meeting and solving the problems of lifeC. life is difficult because our problems bring us painD. people like to complain about their problems56. The writer probably used just one short sentence in the first paragraph to ______.A. save spaceB. persuade readersC. get readers’ attentionD. make readers laugh57. According to the passage, we give school children difficult problems to solve in order to______.A. teach them to fear the pain of solving the problemB. encourage them to learnC. help them learn to deal with painD. teach them how to respect from problems58. The main idea of Paragraph 3 is that ______.A. most people feel life is easyB. most people complain about how hard their lives areC. the writer feels life is easyD. the writer likes to complain about his problemsCWalking down a path through some woods in Georgia, I saw a small pool of water ahead on the path. I angled my direction to go around it on the part of the path that wasn't covered by water or mud. As I reached the pool, I was suddenly attacked!Yet I did nothing for the attack. It was so unpredictable and from somewhere totally unexpected. I was surprised as well as unhurt though I had been struck four or five times. I backed up a foot and my attacker stopped attacking me. Had I been hurt I wouldn't have found it amusing. And I was laughing. After all, I was being attacked by a butterfly!Having stopped laughing, I took a step forward. My attacker rushed me again. He charged towards me at full speed, attempting to hurt me but in vain. For a second time, I took a step backwards while my attacker paused. I wasn't sure what to do. After all, it's just not everyday that one is attacked by a butterfly. I stepped back to look the situation over. My attacker moved back to land on the ground. That's when I discovered why my attacker was charging me only moments earlier. He had a mate and she was dying.Sitting close beside her, he opened and closed his wings as if to fan her. I could only admire the love and courage of that butterfly in his concern for his mate. He had taken it up on himself to attack me for his mate's sake , even though she was clearly dying and I was so large. He did so just to give her those extra few precious moments of life, should I have been careless enough to step on her. His courage in attacking something thousands of times larger and heavier than himself just for his mate's safety seemed admirable. I couldn't do anything other than reward him by walking on the more difficult side of the pool. He had truly earned those moments to be with her, undisturbed.Since then, I've used that butterfly’s courage as an inspiration and to remind myself that good things are worth fighting for.59. The writer changed his direction while walking down a path because he want__________.A. To get close to a butterfly.B. To escape a sudden attack.C. To look over the bad situation.D. To avoid getting his shoes dirty.60. What made the man feel funny?A. Making the attacker pause.B. Being stepped on by his mate.C. Discovering the angry butterfly.D. Being attacked by a butterfly.61. Which of the following words can best describe the butterfly?A. carelessB. amusing D. aggressive D. courageous62. From this experience the man learned_____.A. how he should deal with attacksB. how to deal with challenges in his lifeC. people should protect butterfliesD. people should show sympathy to the weakDAs you grow older, you’ll be faced with some challenging decisions—like whether to cut class or try cigarettes. Making decisions on your own is hard enough, but when other people get involved and try to pressure you one way or another it can be even harder. People who are your age, like your classmates, are called peers(同龄人). When they try to influence how you act, to get you to do something, it’s called peer pressure.Peers can have a positive influence on each other. Maybe another student in your science class taught you an easy way to remember the planets in the solar system. Maybe you got others excited about your new favorite book, and now everyone’s reading it. These are examples of how peers positively influence each other.Sometimes peers influence each other in negative ways. For example, a few kids in school might try to get you to cut class with them; your soccer friend might try to convince you to be mean to another player and never pass him the ball.It is tough to be the only one who says “no” to peer pressure, but you can do it. Paying attention to your own feelings and beliefs about what is right and wrong can help you know the right thing to do.You’ve probably had a parent or teacher advising you to “choose your friends wisely.” Peer pressure is a big reason why they say this. If you choose friends who don’t cut class, smoke cigarettes, or lie to their parents, then you probably won’t do these things either, even if other kids do.If you continue to face peer pressure and you’re finding it difficult to handle, talk to someone you trust. Don’t feel guilty if you’ve made a mistake or two.63. What is the topic of the passage?A. Friendship.B. Self-confidenceC. Peer pressureD. Making decisions64. In the last three paragraphs, the author mainly_____.A. explains why friendship is so importantB. discusses how peers influence usC. shows how to make more good friendsD. gives advice on how to deal with peer pressure65. Which of following may help handle peer pressure?A. Spending more time with classmates.B. Choosing friends with no bad habits.C. Taking up more relaxing hobbies.D. Helping others who are in trouble.VI、单词拼写：（共10小题，每小题1分，满分10分）66. Mike’sfamilyusedtoliveina_______(欧洲)country.67 Take the __________ (伞)with you, Tom. It’s raining outside.68.
