It turned out that the dog had indeed been spending most of his time around that crossroad,but a woman had been coming round regularly to bring him food and water.One day,while photographing the dog everyone called Leo,a reporter met the woman who had been taking care of him.She had come to drop off some food.After learning the story about the dog and the woman,the reporter decided to share the story on social media.The post soon went viral and the photos of Leo got shared hundreds of times.And the photos reached the eyes of Leo^former old owner.Nang Noi Sittisarn,a64-year-old woman from Thailand’s Roi Et Province,almost had a heart attack when her daughter showed her a photo of the beloved dog named BonBon she had lost during a car trip.When she learned that he had been waiting for her in the same spot for the last four years，her heart melted(融化).Auntie Noi told her daughter to drive her to where the dog was waiting.When she got there and called his name.BonBon，the poor dog started wiggling(扭动)his tail and came to her，but when she tried to take him home with her,he was unwilling to follow.

or homelands,are disappearing.Traditional migration paths take birds through countries that are not protecting the places for birds to stop,rest and feed.The scientists studied the migration or flight paths of almost1,500species.They decided that91percent of them passed through dangerous areas.The major danger for migratory birds is development.Buildings and pavements have covered the places where birds stop and feed as they move from one part of the world to another.One of the scientists who worked on the study says“Many of these important places have been lost to land reclamation(开垦)because of urban,industrial and agricultural land expansion”.The problem,according to scientists,is that many of these small birds die along their migration paths because they don’t have a safe place to feed and rest.There is no place to restore their energy for the next part of their journey.Countries in North Africa, Central Asia and those along the coasts of East Asia are having the most difficult time in protecting land.The scientists say these countries do not have enough areas that are safe for birds.One species that doesn’t exist now is the Eskimo curlew.“Our world gets poorer every time we lose a species,”one of the scientists says.The researchers say countries need to work together and come up with safe stopping areas for birds that pass through their boundaries.For example,one country might have preserved safe zones for migrating birds.But a neighbor country might not.A bird might die.One scientist who is not connected with the report tells Los Angeles Times that while some habitats are changing,more work can be done to make urban areas safe for birds.He says small changes,like planting more native plants or keeping cats out of the areas birds would be likely to use,could make a big difference.8.What mainly caused the disappearing of birds’habitats?A.The decrease of awareness to protect birds.B.Natural disasters.C.Overuse of land by human beings.D.The rising sea level.9.What may be the main reason for many birds’death on the way of migration?A.Exhaustion and hunger.B.Beast attack on the ground.C.Hunting of humans.D.The long journey.10.According to the last two paragraphs,how should we protect the migrating birds?A.By keeping fewer cats or dogs.B.By restoring their destroyed habitats.C.By helping change the birds’migration paths.D.By preserving the ecological environments on their migration paths.11.What is the author’s purpose in writing the passage?A.To tell us a huge percentage of bird species are in danger.B.To analyze the reasons for disappearing of birds’habitats.C.To offer some solutions to the problem of birds’habitats.D.To call on people to protect the birds’habitats.DThe biggest challenge faced by travelers especially those who like to have a hiking trip is how to ensure a steady supply of clean clothes.Now,thanks to a great invention called Scrubba Wash Pack,that worry may be a thing of the past.The portable washing machine was invented by Ash Newland in2010,while planning to climb Mt.Kilimanjaro.Struck by the limited packing space,he got inspiration from traditional washboards to create a bag that could be used to clean clothes.Then he gave up his career as a lawyer and focused on perfecting the bag’s design.By2012,the bag was ready for the public.It weighed only180grams and required very little storage space,making it perfect for anyone wishing to travel light.Not surprisingly,the bag worth55dollars was an instant hit with travelers, university students and even passengers.However,Newland was not satisfied.He still saw a disadvantage with his invention–dirty clothes had to be carried around in a separate bag!The recently introduced Scrubba Wash Pack solves that problem.In order to make the pack active,dirty clothes are placed inside the bag along with two to three liters of water.The bag is then shut tightly to ensure all air is squeezed out and the clothes are massaged(揉搓)for a few minutes.After a quick wash,they are clean and ready to be dried.According to Newland,the pack can clean anything from jeans to smelly socks!What’s even more amazing is that with a capacity to hold13 liters of water,it can be used to wash more clothes at a time.The best part is that the99-dollar pack that will be available for sale later this year, only weighs300grams and is completely foldable,making it easy to store when it’s notin use.With the Scrubba Wash Pack,wandering through foreign cities searching for a washing shop,or paying for washing machines may soon be a thing of the past!12.What aroused Ash Newland’s desire to create the Scrubba Wash Bag?A.Travelers’requirements.B.His own experience.C.His dream of invention.D.A traditional washboard.13.Why wasn’t Ash Newland satisfied with his former invention?A.The bag was not convenient enough.B.The bag was not popular with travelers.C.The bag couldn’t wash more clothes at a time.D.The bag couldn’t be folded up.14.Which word can best replace the underlined word in paragraph4?A.Blown.B.PushedC.Figured.D.Run.15.It can be inferred that the improved Wash Pack______.A.will lighten the burden on housewivesB.will replace the traditional washing machinesC.will be widely used by more travelers in the futureD.can encourage more people to travel a long distance第二节（共5小题；每小题2.5分，满分12.5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。

第一部分阅读（共两节，满分50分）第一节（共15小题；每小题 2.5分，满分37.5分）Passage AFive years ago, my wife said she'd found us a tiny but adorable house. It was close to thehistoric Abbot Kinney. However, there was a bus depot（公共汽车停车场）across the street.Hundreds of buses noisily parked there every night and noisily left every morning. It was awful.But I was determined to make the best of it. “It is noisy, but it offers us a good way to think about what is required to make a city work, "I kept telling our 6-year-old daughter.Then one morning, I woke up to find that the buses were gone! I allowed myself to getexcited. My daughter, however, was unhappy. It took me a minute to understand:she had got usedto the idea of us having a role in city life.Shortly afterward, a homeless encampment（临时营地）was built there. Then I found outwhat was planned for the bus depot-a place to deal with the homeless.ig smile spread across her face. Her When I told my daughter about the“bridge housing", a bfirst reaction wasn't fear or selfishness. She understood instantly how special it was that the busdepot would become a place for people who needed just that to live.What story about city life could I tell her then？I tried to keep fruit in the car so that at trafficlights, we could hand out a banana or an apple. When a woman put up a tent on the sidewalk infront of our stairs, I filled all her water bottles.Now we have a couple hundred new neighbours, and I'll be telling anyone who will listenwhat an honour it is to live among the homeless. Without my daughter, I might not have come tothe same conclusion.1.What was wrong with the author's new house at the beginning?A. It was too small for family use.B. It was too close to a tourist attraction.C. There was too much noise around.D. There were too many neighbours around.2. Why was the author's daughter unhappy when she found the buses were gone?A. She thought she lost the role in city life.B. She didn't like the idea of bridge housing.C. She had been used to the presence of buses.D. She couldn't go out of town without the buses.3 . What was the author's purpose of keeping fruit in his car?A. To meet his family's needs.B. To make his daughter happy.C.To thank those who had helped them.D. To help the homeless when possible.Passage BThe next time you need to get somewhere, you may be able to follow your nose. A study hasfound that a strong sense of smell is associated with a strong sense of direction.Researchers conducted an experiment at McGill University in Canada. Fifty-seven adultswere invited to participate in a virtual"way-finding task"in which they had to make their wayaround a virtual environment. They were given 20 minutes to learn about the virtual city. Afterhaving passed by each of eight landmarks at least twice, the participants were placed in front ofone of the landmarks and asked to find the most direct route to one assigned by the researchers.The participants also smelled 40 scented（有香气的）pens one at a time. After a brief sniff,the participants chose one word that best identified the smell from four words on a screen.An additional exercise used a virtual maze（迷宫）to determine if the participants were morelikely to rely on landmarks to find the way or if they used a more habit-based method built overtime as people travelled the same route over and over again.What the researchers found was that those with the ability to correctly identify the smells ofthe pens also had the easiest time performing the way-finding task by way of landmarks. A strongsense of smell was not identified in the participants who used the more habit-based method.The connection between the sense of smell and way-finding likely came about as a result ofthe evolution of the nervous system. The original function of the sense of smell in humans mayhave been intended to support our spatial memory.Keep that in mind the next time you get lost going to the dentist. It won't prevent you fromgetting horribly lost, but it's good food for thought along the way.4.How did the researchers carry out the study?A. By using typical landmarks in a real city.B. By combining virtual tests with real-life tests.C. By testing different senses in a virtual environment.D. By collecting routine observation data from the participants.5. What were the participants asked to do after they smelled a scented pen?A. Decide whether they liked the smell.B. Use a sentence to describe the smell.C. Choose a suitable word for the smell.D. Find the landmark that featured the smell.6. Which of the following factors is better related to a strong sense of direction according toparagraph 5?A. More experience in describing things.B. The way of using landmarks.C. Quick adjustment to the virtual world.D. A more habit-based way-finding method.7. The meaning of the word "spatial" underlined in Paragraph 6 relates to _____.A. the situationB. the positionC. the spiritD. the timePassage CI was excited to take my rescue Beagle（比格犬）to the river the other day, as it’s within walking distance of our new home. Having spent her first six years in a cage, Georgie had neverseen a body of water, and I wanted to get there before sunset to watch her experience it.I was growing increasingly impatient about all the stops her little Beagle nose required. Sheinspected the grass, dirt, and trees, and licked（舔）whatever was stuck to the road. These were allnew discoveries for her, and she took her time studying them.When I accepted that it was fruitless to hurry her along, I whipped out my cell phone andbegan texting. I thought that I needed something to do while Georgie was slowing us down. Then,for some reason, I heard the cicadas（蝉），and I remembered that the sound of cicadas is myfavorite sound in the world. That awakened something buried within me that longed for the simplepleasures that had been replaced by technology.I made a conscious decision to be present, and to enjoy the journey to the river just likeGeorgie. Now, I admired the flowers and the winding ivy on our path. I smelled the grass and theflowers, and the dirt and the air. I treasured each one equally, as if discovering them for the first time.As we neared our destination, 1 realized something even more important: It didn't matter ifwe even reached the river. Why must there always be a destination? Georgie had no idea that we had a destination. She was present for the journey, and she savored every bit of that sweet experience. There was no race and no finish line.Now I'm not sure who rescued whom.8.Why did the author take out the cellphone?A. To kill time.B. To awaken the simple pleasures.C. To hurry the dog along.D. To record the sound of cicadas.9. What is the fourth paragraph mainly about?A. How I enjoyed the journey.B. What I saw on the way.C. Why I traveled to the river.D. Whether I reached my destination.10. What does the underlined word“savored” in the fifth paragraph mean?A. Smelt.B. Expected.C. Enjoyed.D. Deserved.11. What is the best title for the text?A. Say Goodbye to Cell PhonesB.Travel toward DestinationsC. Learn to Get along with PetsD. Think like a DogPassage DRumors: we’ve all heard some and we’ve all spread some. In more traditional times they shook entire families. Today, they circulate differently because the way we share information has also changed.The fact is that rumors have great potential to upset things, whether socially or personally.We don't enjoy being on the receiving end of one, since they usually don't have good intentions. They are somewhat veiled (掩饰的) messages.Normally rumors are oral messages: word of mouth. The paradox (自相矛盾) is that there is no evidence to support rumors, but the more people share it, the more they see it as true. To finish defining rumors, we think that they follow certain very clear laws. Secrecy: The source is unknown. There is also a proven phenomenon that human beings usually forget the source of a message before they forget its content. Certainty: We hardly question rumors simply because ofthe mental effort involved. On the other hand, no one likes to doubt a person who convinces usthat the information they spread is true. Change: It acts like a tree. New rumors branch out to fillin the gaps left by the initial rumor.Another property of rumors is that they tend to become viral. Each receiver is at the same time a potential transmitter of the information. The receiver often adds their own opinion. Their manner and tone of transmitting it also changes it.How can we end rumors? The answer is as simple as it is impossible: preventing people from communicating. A more realistic response is equally difficult, although less than the first one. It is that we should be critical of the information we receive. We should ask ourselves if the source is reliable. Ask (if possible) the person you heard it from whether they also trust the information. We should also think about if the rumor benefits someone, and if that someone started the rumor.One rumor to be especially cautious of is a rumor about groups relatively unable to defend themselves. That's why we say, “history is always told by the victors.”The first payment the defeated must make is to accept the victor’s version of the story.12. What can we learn about rumors?A. We have all heard some and believed them.B. They may have negative influence on society.C. We’re happy to be the receiving end of them.D. They often hide good intentions in the messages.13. How are rumours like trees?A. Rumours keep changing, just as trees change their colour.B. Rumours are deeply rooted in reality, like tree roots in the earth.C. New rumours have gaps, like the space between tree branches.D. New rumours grow out of the original, like branches out of a trunk.14.What does the underlined word “'viral”in Paragraph 4 probably mean?A. Something easily spread.B. Something acceptable.C. Something easily defended.D. Something beneficial.15.Which of the following may the author agree with?A. It is easy to prevent people from spreading rumors.B. People are often active in judging the rumors critically.C. We should think about the hidden message of the rumors.D. Stories told by the victors are usually better worth trusting.第二节七选五（共5题；每题 2.5分，共12.5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。

Now, thanks to a great invention called Scrubba Wash Pack, that worry may be a thing of the past.The portable washing machine was invented by Ash Newland in 2010, while planning to climb Mt. Kilimanjaro. Struck by the limited packing space, he got inspiration from traditional washboards to create a bag that could be used to clean clothes. Then he gave up his career as a lawyer and focused on perfecting the bag’s design. By 2012, the bag was ready for the public. It weighed only 180 grams and required very little storage space, making it perfect for anyone wishing to travel light.Not surprisingly, the bag worth 55 dollars was an instant hit with travelers, university students and even passengers. However, Newland was not satisfied. He still saw a disadvantage with his invention –dirty clothes had to be carried around in a separate bag! The recently introduced Scrubba Wash Pack solves that problem.In order to make the pack active, dirty clothes are placed inside the bag along with two to three liters of water. The bag is then shut tightly to ensure all air is squeezed out and the clothes are massaged (揉搓) for a few minutes. After a quick wash, they are clean and ready to be dried. According to Newland, the pack can clean anything from jeans to smelly socks! What’s even more amazing is that with a capacity to hold 13 liters of water, it can be used to wash more clothes at a time.The best part is that the 99-dollar pack that will be available for sale later this year, only weighs 300 grams and is completely foldable, making it easy to store when it’s not in use. With the Scrubba Wash Pack, wandering through foreign cities searching for a washing shop, or paying for washing machines may soon be a thing of the past!12.
