But did you know that there's a small frog in the Pacific Northwest that belly flops (肚子先着水)? It's called a tailed frog.Dr. Rick Eisner, who has been studying tailed frogs for the past few years, says, "I've looked at thousands of jumps and have never seen them land on their feet like other frogs." Most of the time, tailed frogs land on their stomachs and then bring their back legs in to prepare for another jump.Eisner first noticed these frogs because of the way they swim. Other frogs kick both of their back legs at the same time. But when a tailed frog swims, it pushes first with one leg and then the other.To try to find out why tailed frogs bellyflop, Eisner and other scientists collected and filmed different kinds of frogs. They found that all of the frogs start their jumps the same way: They hold out their legs. The change comes in the landing. Tailed frogs can't move their back legs as quickly as other frogs do. Maybe they don't need to. Tailed frogs live around water and quickly jump into the water to escape danger.Early frogs developed around watery areas and could jump quickly into the water to escape danger. Scientists think those frogs blended in with (与…融合在一起) the green plants on the side of the rocky rivers, just like today's tailed frogs. "I would guess that other animals would have problems detecting them," explains Eisner. When other animals find those early frogs, the frogs could jump into the river. They didn't need to continue hopping.Tailed frogs and other kinds of frogs went their own ways about 200 million years ago. Tailed frogs stayed by rivers. Other kinds of frogs moved to places where new hopping skills allowed them to survive.（1）What's special about the detailed frog?A. It has a long tail.B. It jumps on one foot.C. It stars its jump differently.D. It lands differently from other frogs.（2）Why do tailed frogs bellyflop?A. They have never left the water to live.B. They have trouble in holding out their legsC. Their back legs can't catch up while jumping.D. Their front legs develop better than the back ones.（3）The underlined word "detecting" in Paragraph 5 means "________".A. eatingB. killingC. usingD. discovering（4）When they are in danger, the detailed frogs would ________.A. jump into the water for protectionB. hop around quicklyC. hide in the green plants near the riverD. jump into the rockBWhen seven-year-old Sky Nockels learned that black rhinoceroses (犀牛) were an endangered species, he decided to do something to help them. He raised money to adopt (收养) a black rhino named Imara at the Great Plains Zoo in South Dakota. By adopting Imara, Sky helps the zoo take care of the rhino's needs, such as food and a good habitat.Sky has been a summer camp member at the Great Plains Zoo since he was three. There he and other kids learnt about the animals and did projects for them. “We made juice drinks for the bears,” says Sky. “They enjoyed them.”Now that Sky is older, he is playing an even more active role in the care of the animals. Since black rhinos are one of Sky's favorite animals, he decided to adopt Imara first. “I adopted a Grevy's zebra named Demani, too, for my little brother Alexander,” h e says.Sky raised money to help care for the animals he wanted to adopt. He promised to raise $75 for his rhino and $25 for Alexander's zebra. To earn the money, Sky and his grandfather planted a vegetable garden. Sky planted seeds (种子), watered, and cleared the grass. When the time came, he harvested the vegetables and sold them in front of his parents' store.When Sky's friends heard about this, they brought vegetables from their parents' gardens to sell, too. With the help of his friends, he earned enough money to keep his promises.Sky is one of the youngest people to adopt an animal at the Great Plains Zoo. He cares about the animals and plans to plant and sell vegetables again this summer to help them. “I hope other children do something t o help animals, too,” he says.（1）The passage is written mainly to ________.A. explain why rhinos are endangeredB. show children how to adopt animalsC. tell a story about how a kid helps animalsD. let us know more about endangered animals（2）The underlined word “them” in Paragraph 2 refers to ________.A. other kidsB. animalsC. the bearsD. juice drinks（3）According to the passage, Sky raised money by ________.A. working in his parents' storeB. selling vegetables he plantedC. working in other people's gardensD. helping Grandpa plant a garden（4）Which of the following words can best describe Sky?A. Worried.B. Kind-hearted.C. Frightened.D. Easy-going.四、改错题假定英语课上老师要求同桌之间交换修改作文，请你修改你同桌写的以下作文。

I told myself “Smile! It’s not so serious.”I smiled a big smile and 2 worked a little, really.Everyone gets 3 （frustrate）sometimes. I used to be always influenced by pressure and I was often in low spirits. But one day I came 4 a sentence in the Bible: “Do not be anxious about tomorrow, for tomorrow will be anxious for itself. Let the day’s own trouble be sufficient for the day.” It suddenly struck me “ 5 （worry）about a problem doesn’t help. Why not just give a big smile and face up 6 the trouble?”Now every time I want to cry, I remind myself that 7 （laugh）is better than tears and anger. I am 8 （convince）that there’s something magical about a smile. A smile helps me recover confidence and gives me 9 courage to move on.Remember, whenever you’re faced with a setback, whenever you’ve been treated unfairly, all it takes is determination and you can feel happy again. Smile at life, 10 it will shine on you.Ⅲ. 阅读理解Dear Friend,Hi! My name is Sharda Baker and I’m bursting to share something with you.There’s an amazing new e-book on the Border Collie(边境牧羊犬) to assist you in having the absolutely best experience with your Border Collie.I remember the first puppy （幼犬）we bought , Shani. She was a 7—week old female. Her favorite sleeping place used to be in one of my husband’s old leather shoes.I didn’t know then what questions to ask the breeder or what to look for when we went shopping for her. To cut a long story short we spent over $2700 on Shani over the first 2 years for 2 knee repairs and countless visits to the vet for on going allergy problems.If only I had known then w hat I know today about Shani’s diet, exercise and general needs we wouldn’t have had to pay all that money and go through that stress. I guess in a way its a bit like buying a car. If you don’t know what to look for can easily end up with a car that is not really in good condition.Our second puppy “Ellie”, we bought her when she was 16 weeks old. Puppies are so cute at that age, aren’t they? We didn’t know how to tell if a puppy has been socialized well or not. Well, we got home with a dog that was real hard work for several months. Ellie was so timid, barked all the time, was very slow learning anything and took a while to take to any visitors. We went though the hard way again! But things have changed now!Our last few dogs have been almost perfect. OK they have been to the vet once or twice for their shots but we’ve had no major expenses in the last 6 years.1. What’s the main idea of this passage?A. The moving stories about raising dogs.B. The difficult experiences of raising dogs.C. Advertising an e-book on the Border Collie.D. Introduction of best Border Collie in the world.2. What can we learn from the third paragraph?A. Shani is too naughty to get her leg broken.B. Shani takes the author’s too much energy to raise.C. The author lacks knowledge about raising Shani.D. The author lacks money to take care of Shani.3. Why the author mentioned “buying a car” in paragraph 4?A. To show the importance of how to buy a car in good condition.B. To prove the importance of knowing how to raise a dog.C. To present his rich knowledge about buying cars and dogs.D. To make a comparison with buying a best Border Collie.4. What’s Ellie’s shortcoming?A. She is too cute.B. She barks too much.C. She is too brave.D. She always eat too much.5. Where does this article probably come from?A. A story book.B. An ad Internet.C. A magazine for teens.D. A travel guide.Ⅳ. 七选五They say a teacher’ s work place is his second home. 1. ______ Thus teachers and students at school tend to become like a family. This Teachers’ Day, being the moment of giving gifts to our loved ones, how could we miss our teachers?Below are a few gift ideas for you that could come handy while choosing the best gift for this Teacher’s Day:T ea SetGenerally people at work are tea lovers. On this day you could gift your teachers a tea set containing a pair of attractive tea kettles. 2. ______Wind Chimes (风铃）3. ______ It brings happiness and spreads across the whole atmosphere. Wind chimes make a perfect gift for festivals because it clears of the mind from stress especially in a stressful atmosphere at work. Thus wind chimes are definitely a recommended gift for this day.Desk ClockAt work, in an atmosphere filled with deadlines and lots of work, a desk clock could be reallyhelpful. So a desk clock could be a good gift for your teachers. There are different desk clocks available in the market or you could even search online for desk clocks of different shapes and sizes.4. ______These are a few ideas hopefully helping you find the most suitable gift for your teacher. If you want the gift to be special, make sure it is given thoughtfully and not just a formality. 5. ______A. They say a pleasing sound can instantly change your mood from bad to good.B. Gift your teachers a bottle of red wine.C. Just make sure it has a long lasting battery life and tells the time accurately.D. It would come really handy for them especially when teachers seem to get a lot of guests.E. This is because generally after their own homes teachers spend most of time at work.F. They not only bring good luck but also improve relationships at the workplace.G.

And, what's more, it may pushthem up the corporate ladder past their humorless colleagues. Why? It seems that those with a sense of humor are better communicators and better team players.Studies have shown that happy workers are more productive. In fact, a researcher at California State University found that humor could help the employees to release tension. Research done by psychologist Dr. Ashton Trice at Mary Baldwin College in Virginia showed that humor helps us think. When people feel stuck on important projects, they tend to feel angry or depressed. According to Dr. Trice's research, taking time out to laugh can help us to get rid of negative feelings and allow us to retur n to a task or move on to another project unaffected by past defeat.If humor is really this important, then why don't we use it more often on the job? Most likely, the main reason is that many people are unaware of the positive effects of humor in the workplace. However, it is important to realize that some humor is not suitable for the workplace, and that it is often used at wrong times.1. Most people think a sense of humor can ________.A. help you to do your work betterB. make you have a rich lifeC. make you pleased with your workD. help you to make more friends2. Many people don't use humor more in the workplace because ________.A. they like keeping silent when workingB. they don't know the positive effects of humorC. they think they should obey the rulesD. they don't like joking or laughing3. A person without a sense of humor is easier ________.A. to feel surprisedB. to get along withC. to be worriedD. to be successful4. What is probably the best title for the article?A. People with a Sense of HumorB. Humor Is Important in the WorkplaceC. Humor and HumorlessD. Everyone Likes Humor题二十：Several times my daughter had tel ephoned to say, “Mum, you must come and see the daffodils (水仙花) before they are over.” I wanted to go, but it was a twohour drive from Lake Arrowhead. “I will go next Tuesday,” I promised, a little unwillingly, on her third call.The next Tuesday dawned cold and rainy. Still, I had promised, and so I drove there. When I finally walked into Carolyn's house and hugged and greeted my grandchildren, I said, “Forget the daffodils, Carolyn! The road is invisible (看不见的)in the cloud and fog, and there is nothing in the world except you and these children that I want to see！”My daughter smiled calmly and said, “We drive in this weather all the time, Mum. You will never forgive yourself if you miss this experience.”After abo ut twenty minutes, we turned onto a small road and I saw a small church. On the far side of the church, I saw a hand-lettered sign that read “Daffodil Garden”.We got out of the car and each took a child's hand, and I followed Carolyn down the path. Then, we turned a corner of the path, and I looked up and gasped. Before me lay the most beautiful sight! There were five acres of flowers! “But who has done this？” I asked Carolyn. “It's just one woman,” Carolyn answered. “That's h er home,” C arolyn pointed to a well-kept A-frame house that looked small and modest in the midst of all that glory. We walked up to the house. On the patio (庭院), we saw a poster. “Ans wers to the Q uestions I Know You Are Asking” was the headline.The first answer was a simple one. “50,000 bulbs (鳞茎),” it read. The second answer was, “One at a time, by one woman.” The third answer was, “Began in 1958.”I thought of this woman whom I had never met, who, more than fifty years before, had begun — one bulb at a time — to bring the beauty and joy to the mountain top.1. The author didn't go to see the daffodils at first because ________.A. she was not interested in themB. they were growing on the mountain topC. the weather was not good enoughD. it was not easy for her to drive there2. What do we know about the woman living in the A-frame house?A. She must be out of mind.B. She acted as a gardener there.C. It took her great determination to grow the daffodils.D. She was poor and made her living by selling daffodils.3. What could the author probably learn from this experience?A. Nothing is too difficult if you put your heart into it.B. We must put the interests of others above our own.C. We can change the world by growing flowers.D. It's never too late to learn.4. W hat would be the best title for the passage?A. An Unforgettable ExperienceB. Beautiful DaffodilsC. One Bulb at a TimeD. I Love DaffodilsUnit4 Wildlife protection(二)课后练习参考答案题一：D解析：本句意为：据报道现在在灾区许多新房子正在被建造。

To get to the other side.Most people know this joke.But recently, some people have been much more worried about how the grizzly bear and the mountain lion can cross the road.“Millions of animals die each year on the US roads，” the Federal Highway Administration reports.In fact, only about 80 ocelots, an endangered wild cat, exist in the US today.The main reason? Roadkill.“Ecopassages” may help animals cross the road without being hit by cars.They are paths both over and under roads.“These ecopassages can be extremely useful, so that wildlife can avoid road accidents，” said Jodi Hilty of the Wildlife Protectio n Society.But do animals actually use the eco-passages? The answer is yes.Paul Beier of Northern Arizona University found foot marks left by mountain lions on an eco-passage that went under a highway.This showed that the lions used the passage.Builders of eco-passages try to make them look like a natural part of an area by planting trees on and around them.Animals seem to__be__catching__on．Animals as different as salamanders and grizzly bears are using the bridges and underpasses.Next time you visit a park or drive through an area with a lot of wildlife, look around.You might see an animal on an overpass!1．The writer uses the example of ocelots to show that ________．A．wild animals have become more dangerousB．the driving conditions have improved greatlyC．the measure for protecting wildlife fails to workD．an increasing number of animals are killed in road accidents2．When the writer says that animals seem “to be catching on”，he means ________．A．animals begin to realize the danger on the roadB．animals begin to learn to use eco-passagesC．animals are crossing the road in groupsD．animals are increasing in number3．This passage is written to ________．A．protect the endangered animalsB．call on drivers to be careful when seeing animals on the roadC．introduce a new way to help protect wild animalsD．tell us the main reason for the killing of animals in the USBFood webs throughout the ocean are in trouble because of overfishing.About one billion people rely on seafood for protein.However, people are fishing more species faster than those fish can reproduce(繁殖)．By 2048, says the World Wildlife Fund, the number of all present food fish could reduce by 90%.So few fish would remain in the world that people couldn't depend on them for food.Climate changes will most likely trouble food webs further.As average global temperatures rise, the ocean gets more carbon dioxide.That makes the ocean more acidic, which does harm to the lives in the ocean.Fewer of those lives will grow stronger, leaving less to eat.There will be more effects on the food web.Aquaculture—raising fish and seafood in farms—isn't necessarily the answer to these problems. Sometimes companies destroy mangrove(红树林) forests and other sensitive habitats in order to build fish farms. Habitat destruction also leaves coastal areas easily flooded.“A lot of our freshwater comes from the ocean as rain，” says Shannon, an ocean scientist. Rain helps crops grow and provides drinking water.But it__can__have__a__dark__side，as when hurricanes cause flooding and blackouts even in inland states, such as Ohio, Missouri, and New Mexico.The ocean affects the air, too.“Half the oxygen that we breathe comes from photosynthesis(光合作用) of sea plants in the ocean，” adds Shannon.That sea air reaches from coast to coast.All those reasons suggest that we have to protect the ocean before it is too late.4．By saying “it can have a dark side”，Shannon means ________．A．rain can make drinking water darkB．rain can have a bad effect tooC．rain can get crops grow darkD．rain can become dark itself5．Which of the following is RIGHT according to the passage?A．By 2048, about one billion people will not depend on seafood any longer.B．Climate changes will most likely cause a lot of trouble to food webs.C．Aquaculture is necessary to solve these problems.D．The ocean and the seafood affect our surroundings.6．The purpose of this passage is to ________．A．prove the advantages of seafoodB．introduce the serious sea pollutionC．explain the formation of food websD．call on people to protect the oceanCWhen I first entered high school, I knew no one at my school.All my friends in middle school went to other schools.I wanted to make some new friends.However, I was shy and wasn't good at making new friends.On my first day at school, I looked at others who were talking in groups happily.How I wish I were one of them!I guess I was very lucky then.At lunch in the dining hall, when I was eating at a table alone, a girl came t o me.“Excuse me, is this seat taken？” she asked.I immediately shook my head.She smiled and sat down opposite to me.I felt a little awkward and didn't know what to say at all, but I really wanted to communicate with her.It was a good opportunity to make friends with her.When I looked up, I found she was smiling at me.Her smile calmed me down.“I really like this school.It's beautiful, but I don't know anyone here.All my friends went to other schools，” said the girl.Hearing her words, I immediately said, “My f riends are not here either.Can we be friends？”I was surprised.I couldn't believe I would say something like that, and to my surprise, that girl immediately said “yes”．We both smiled.We became very good friends.Now it's the beginning of a new term again.Many students may have no friends at their new schools.If you are also as shy as I used to be, please don't be afraid to talk to others.You may get a surprise and make a new friend.After all, others want to make new friends, too.7．We know on her first day at school, the author ________．A．hoped she could make some new friendsB．only knew a few people at her schoolC．met some old friends at her new schoolD．hoped she could go to her old friends' schools8．The underlined word “awkward” in Paragraph 2is closed in meaning to “________”．A．bored B．excitedC．interested D．embarrassed9．After the girl sat down opposite to the author, the author ________．A．immediately shook her handB．immediately said something to keep calmC．wanted to talk with herD．wanted her to go away at once10．What's the author's purpose in writing the passage?A．To show that high school is really exciting.B．To encourage shy people to talk to others.C．To tell us how lucky she was in high school.D．To advise us to have a good first day in high school.Ⅳ概要写作阅读下面短文，根据其内容写一篇60词左右的内容概要。

It was calculated that when its population reached its highest point，there were more than 3 billion passenger pigeons—a number equal to 24 to 40 percent of the total bird population in the United States，making it perhaps the most abundant bird in the world.Even as late as 1870 when their numbers had already become smaller，a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati. Sadly，the abundance of passenger pigeons may have been their undoing.Where the birds were most abundant，people believed there was an ever-lasting supply and killed them by the thousands.Commercial hunters attracted them to small clearings with grain，waited until pigeons had settled to feed，then threw large nets over them，taking hundreds at a time.The birds were shipped to large cities and sold in restaurants. By the closing decades of the 19th century，the hardwood forests where passenger pigeons nested had been damaged by Americans' need for wood，which scattered (驱散) the flocks and forced the birds to go farther north，where cold temperatures and spring storms contributed to their decline.Soon the great flocks were gone，never to be seen again. In 1897，the state of Michigan passed a law prohibiting the killing of passenger pigeons，but by then，no sizable flocks had been seen in the state for 10 years.The last confirmed wild pigeon in the United States was shot by a boy in Pike County，Ohio，in 1900.For a time，a few birds survived under human care.The last of them，known affectionately as Martha，died at the Cincinnati Zoological Garden on September 1,1914. 语篇导读：本文介绍了在美国生活的旅鸽从数量巨大、铺天盖地到踪迹难觅、逐渐灭绝的经过。 1.In the 18th and early 19th centuries，passenger pigeons________. A．were the biggest bird in the world B．lived mainly in the south of America C．did great harm to the natural environment D．were the largest bird population in the US 答案：D 解析：考查推理判断。根据第二段的内容可知，据计算，旅鸽数量最多时，有30多亿只，相当于美国鸟类总数的24%—40%。到1870年，旅鸽的数量已经减少了，但是，有人在Cincinnati附近看到鸽群的规模为1英里宽，320英里长。由此可见，在18至19世纪，旅鸽的数量最多。第一段的第二句也是关键信息。 2.The underlined word “undoing” probably refers to the pigeons'________. A．escape B．ruin C．liberation D．evolution 答案：B 解析：考查词义猜测。根据第三段的内容可知，旅鸽的数量巨大最终导致它们灭绝。undoing意为“毁灭”，与ruin同义。 3.What was the main reason for people to kill passenger pigeons？ A．To seek pleasure. B．To save other birds. C．To make money. D．To protect crops. 答案：C 解析：考查细节理解。根据第三段可知，商业猎人用大网来围捕旅鸽，然后运到大城市卖给餐馆，由此可见，人们捕杀旅鸽主要是为了赚钱。 4.What can we infer about the law passed in Michigan？ A．It was ignored by the public. B．It was declared too late. C．It was unfair. D．It was strict. 答案：B 解析：考查推理判断。根据最后一段的内容可知，1897年密歇根州出台了法律，禁止捕杀旅鸽。此时，人们已经十年没有看到大规模的旅鸽群出没。由此可知，保护旅鸽的法律出台太晚了。 Ⅳ.完形填空 (2015·昆明一中一模) He lost his arms in an accident，where his father lost his life.Because his father was the main__1__of support for the family，since then，he has had to totally__2__his brother.Except for writing with his__3__，he himself could do nothing else.
