along the street i saw something heartbreaking: a bloodied and limping(跛行) dog was half-running alongside my car on his way home. i knew he was on his way home because after trying to get him into my car by offering him something to eat, he just gave me a look and continued on his way to a front yard where he finally stopped. without thinking, i immediately pulled over and grabbed a first aid kit i kept under the passenger seat.with the first aid kit in hand, i knelt in front of the injured dog which weighed more than 80 pounds and looked sympathetically at him. he licked my hand. holding a gauze pad(纱垫), i proceeded to treat his wounds. he had lost a lot of blood and i was worried about dehydration(脱水)from the extreme heat.although my actions merely cleaned his wounds and wrapped them up with bandages, i had done enough to inspire his owners. the owners wondered why there was a stranger kneeling down and touching their dog and came out to find out what was going on. they didnt even know he had gone missing. i explained i had followed him, and that he had been injured from what i considered to have been a dog fight. they said they lacked the money to take him to a vet, so i coached them on how to clean and treat his wounds. they thanked me for my help and showered their injured dog with love, promising to keep a better eye on him and do what i had advised.21. what was the author trying to do while driving along the street?a. search for a house. b. help the dog.c. find the dogs owner. d. look for a vet.22. from this text we can infer that the first aid kit is a box_.a. in which dogs can be carried b. where some treasures are hiddenc. where there are many tools for repairing carsd. in which medical instruments or medicines are kept23. what can we infer from the text about the author?a. he is experienced in selling houses. b. he is sympathetic to poor people.c. he is good at treating animals. d. he hasnt kept dogs as pets.24. inspired by the author, the dog owners decided to_.a. thank the author another day b. take better care of their dogc. treat their dogs eyes d. take the dog to a vetb a new ingredient developed by scientists in scotland could mean that ice cream lovers can enjoy their treats longer before they melt. the scientists predict that the slow-melting product could become available in three to five years. the development could also allow products to be made with less saturated fat(饱和脂肪) and fewer calories.research teams at the universities of edinburgh and dundee have discovered that the protein, known as bsia, works by sticking together the air, fat and water in ice cream. it is also said to prevent gritty ice crystals from forming.professor cait macphee, of the university of edinburghs school of physics and astronomy, who led the project, said: its not completely non-melting because you do want your ice cream to be cold. it will melt eventually but hopefully by keeping it stable (稳定)for longer it will stop it from falling in big drops.the team developed a method of producing the protein , which occurs naturally in some foods as friendly bacteria. according to professor macphee, it works by keeping oil and water mixed together, stops air from escaping and coats the ice crystals in ice cream which stops them from melting so quickly. she says,: this is a natural protein already in the food chain. its already used to ferment（使发酵）some foods so its a natural product. by using this protein, were replacing some of the fat molecules that are currently used to stabilize these oil and water mixtures, so it can reduce the fat content, but it shouldnt taste any different. it can also reduce the sugar content and so be used in other foods to help reduce calories.”the researchers believe using the ingredient could benefit manufacturers too, as it can be processed without having an influence on performance and can be produced from sustainable raw materials.25. the ice cream developed by scottish scientists will_.a. not melt completely b. taste more deliciousc. be much healthier d. appear on the market soon26. what do we know about the protein?a. it doesnt exist in nature. b. it was invented by scientists.c. it is seldom used in food production d. it works like some friendly bacteria in foods.27. according to professor macphee,_.a. the new product will be safe for consumersb. mixing oil and water can reduce the fat contentc. bsia can make the new ice cream taste differentd. bsia can take the place of the fat molecules completely28. the main purpose of the text is to_.a. advertise a new ice cream b. list the benefits of a proteinc. tell readers about a new product d. introduce ways to produce better foodccamping has a long history in australia. the countrys original occupants have a long tradition of what might be called camping to some but it is a simple way of life for them. although that way of life has mostly died out in the modern country we live in now, we must take care to remember this way of life.ever since the first settlers arrived, there has been a connection between the earth we walk on and the earth we sleep on. when gold was first discovered and people came from around the world to find their fortune, many could not afford to stay in accommodation and nor would there have been enough if they had wanted to, and so they all brought tents and set them up. many people alive in australia today are descended from (是的后裔) people who spent a large parts of their lives in tents. come summertime, the nations many camping grounds are packed with families on holidays. taking the opportunity to change the scenery and experience the world a bit closer than they are used to. parents often consider this getting into nature to be a vital part of a childs upbringing; it teaches them early on that there is a different world to the one they know. it is a beneficial experience for a kid to lie in a tent where he or she can hear all the sounds of the bush and the insects and perhaps the waves in the ocean. its a place where they can learn skills, like making a fire, and cooking, or swimming in the water, which they will use for their whole lives.of course, things have changed a lot from the early days of camping, where you would carry everything you needed on your back. now there are all kinds of things you can take with you, from solar panels for your electric razor to an outdoor shower. indeed many campsites you see around the country are so well equipped that you have to wonder why they bothered to leave the house at all.29. what does the underlined pronoun “it” in the first paragraph refer to?a. australia. b. tradition. c. camping. d. occupant.30. the second paragraph mainly tells us about_.a. the history of camping in australia b. what the first settlers did in australiac. the limited accommodation in australia d. australians modern way of life31. the author believes that for a child getting close to nature is_.a. wasteful b. helpful c. powerful d. harmful32. what is the authors attitude towards the over-equipped campsites?a. confident. b. pessimistic. c. supportive. d. opposed.dtate modern is britains national museum of international modern art. it is in london, on the south bank of the river thames, opposite st pauls cathedral and the city of london. it displays examples of modern are from 1900 to the present day. take modern opened in 2000. the building was originally the bankside power station, designed by sir giles gilbert scott, who also designed waterloo bridge and the famous british red telephone box. the power station closed in 1981 and architects herzog and de meuron helped convert it into an art gallery. the building is more than 200 metres long and its chimney is 99 metres high. there are 5 levels and the vast turbine hall. this is where the tate displays large installations(现代雕塑装置) by contemporary artists. one famous example of an installation was a series of huge slides that visitors could go down, leading from the different levels of the building to the hall floor. this, and other popular installations, has helped inspire the imagination of the public, and tate modern is now one of the biggest tourist attractions in london. there are plans to build a glass pyramid extension, dedicated to photography and video exhibitions. many art galleries arrange art chronologically(按时间先后), but tate modern organizes its works of art according to the important movements of the twentieth century. these include abstraction, with paintings by artists like wassily kandinsky; surrealism, with works by artists like salvador dali and max ernst; cubism, with works by picasso; and pop art, represented by artists like andy warhol. there are 3 other tate galleries-tate britain(also in london), tate liverpool and tate st ives in cornwall. tate modern is, however, the most popular.33. the underlined word “convert” in the second paragraph probably means_.a. move b. take c. change d. divide34. the installations in the tate modern can_.a. get people interested in art b. show how famous the museum is c. tell us how valuable the exhibits are d. represent modern art works35. how are the exhibits arranged in the tate modern?a. by popularity. b. by important events. c. by size and shape. d. by time.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，选项中有两项为多余选项。recycling our old mobile phones is something we often mean to do. but by the time we remember to do it, we decide that theyre so old theyre worthless, and we throw them away. but are they really? 36_ “only about 3-4percent of the phones we receive cant be repaired,” says simon walsh, sales and marketing director for a british phone recycler. as a phone arrives at a recycling center, it goes through a strict testing process, which starts with a check to make sure that its not been lost or stolen. 37_ many phones are then passed to specialized repair centers. even mobiles that cant be repaired are valuable. 38_batteries contain nickel(镍) which can be used to make stainless steel. the plastics i phones can be melted down to be made into traffic cones. of the phones that can be reused, about 20% stay in the uk. the rest of them are sent to places in asia and africa where they are specially needed because there are few landlines. but theres more to it than that. its good to recycle and reuse second-hand mobiles from the uk, but the countries which receive the mobiles also need to recycle them. 39_. this is a growing problem because some mobile phone parts contain dangerous chemicals. 40_ the phones electrical circuits(电路) contain lead, which can cause brain damage. its said that there are more than 500 million used mobile phones around the world. if we send all of them to landfills(垃圾处理场), over 130,000 kilos of lead will go into the soil. the even greener alternative to recycling seems almost unthinkable. its to keep your current phone for more than the usual twelve
