Madison surveyed the situation. She was the only one who could fit through the small hole. Without hesitation, she told the adults, "Lower me in. Inside, the tank was dark, and the air was smelly . In the process , she jammed her left wrist against a hidden pole , injuring the muscles in her wrist so severely that the hand was left useless.

ATop dealers compete for your business by offering lower prices. TrueCar spends a lot of money and resources on making sure the entire car renting experience is simple and straightforward. If you’re in the market for a new car, give this site a try first.TrueCar’s network checks many of the prices in your area and gets the best price for the car you’re looking for.It offers more control by allowing you to build your car, and select your rental plan. The “build your car” option is one of the better options for those looking to add features to their car. If you’re looking for cars with options like a sunroof or navigation(导航), it’s Carvoy that makes it very easy to get started with the process.They have a large collection of new and used cars, and also provide resources for car comparisons. In the business for many years, they are one of the first online car outlets. They have a staff that can usually help you if you give them a call. Their phone support is very good and they are mostly located in the United States.It delivers your rental car to the door, which is actually a huge selling point. Many people don’t like to go to a dealership or even drive somewhere to pick up a car. Imagine renting a car and having it delivered right to your doorstep, and you need not drive by yourself.It offers member-only savings, many car selections and an easy sign-up process. The deals through Costco are great and unique. Many times they have deals with General Motors cars like Chevrolet. There are a lot of deals to be done, but the one thing that Costco does not do is negotiate the price.21．What’s the selling point of ?A．Its most reasonable prices for cars. B．The diversity of its used cars.C．Its delivery service to your door. D．The special offers to its members. 22．What is the special service that provides?A．You can have other functions added to your car.B．You can rent a car more easily than elsewhere.C．You can design the whole car by yourself.D．You can have better operation over your car.23．If you are a good bargainer, it’s wise to avoid dealing with ________．A． B．C． D．BDevon Gallagher, a college graduate from Philadelphia, wants the world to know exactly where she’s been during her worldwide vacation in aspecial way.The traveler, who was born with a bone disease, had her right leg amputated(截肢) at the age of four. Although the amputation caused setbacks for Gallagher early on, she now sees it as nothing short of inspiration for living her best life.To spread that message, Gallagher has taken to social media, where she shares photos of her travels across the globe, but instead of simply using a geo-tag, she writes her location across her artificial leg before taking a picture.Now she has been taking pictures across the Continent, which show her cycling over the canal in Amsterdam, relaxing on a wall overlooking the city of Barcelona, posing with a waffle in Brussels, taking spectacular pictures in Athens and enjoying a river cruise in Budapest, all with the well-known locations written on her artificial leg.“I get a new leg every two years and I can choose the design on it. One day I had a sudden thought to get a chalkboard，” Gallagher said. “My mum and grandmother weren’t too keen on the idea, but my friends thought it was great and told me to g o for it, so I did.”Gallagher said people often stare when she’s writing on her leg, but once she shares the photos, she receives only positive feedback. “My leg hasn’t stopped me from doing anythingI’ve wanted to do,” she said. “I don’t know if it’s my determination to prove to myself that I can do it, but regardless, I’ve been able to keep up with my peers and lead a pretty great life.”Gallagher shows us that you should never let anything stand in the way of your dreams. And if life gives you an artificial leg, make art.24．What message did Gallagher want to spread in her special way?A．She enjoys her traveling across the globe.B．She suffers little from her leg amputation.C．She looks on her misfortune as another form of blessing.D．She has exactly fallen in love with posting photos online.25．What does the underlined word “which” in Paragraph 4 refer to?A．The Continent.B．The pictures.C．The leg. D．The locations.26．Gallagher can best be described as ________．A．helpful and ambitious B．friendly and generousC．determined and creative D．independent and sensible 27．Which of the following might be the best title for the text?A．Never Too Late to Share B．A Special Artificial LegC．An Outstanding Photographer D．Gallagher’s Summer Holiday sCMost of the new diseases we humans have faced in the past several decades have come from animals. The more we come into contact with wild animals, the more we risk a so-called disease “spillover” from animals to humans.“As people move and wildlife mov e in response to a changing environment, humans and wildlife and animals will come in contact more regularly,” said Jeanne Fair from the Los Alamos National Laboratory in New Mexico. Fair argues that by shifting animal habitats, climate change will also make the opportunities for disease spillover more frequent. “Everything is sort of shifting and will shift into the future as the environment changes through climate change,” Fair said.Scientists, including climatologists and epidemiologists on Fair’s team at Los Alamos, are beginning to model how changes to the climate will impact the spread of infectious diseases. It’s early days for this kind of research, but previous studies suggest that extreme weather has already played a role in at least one outbreak. Scientists say drought and deforestation have combined to force bats out of rainforests and into orchards（果园）in Malaysia to find food. Those bats, a common disease reservoir, then passed the Nipah virus through pigs to humans for the first time in the late 1990s.“We’re going by the past data to really predict what’s going to happen in the future,” Fair said, “And so, anytime you increase that wildlife-human interface, that’s sort of an emerging disease hot spot. And so, that’s just increasing as we go forward.”Jeffrey Shaman, head of the climate and health program at Columbia University’s public health school, argues we don’t yet know whether climate change will cause a net increase in infectious disease rates globally. For example, mosquitoes carry disease that affects millions of people across the world every year. As their habitats expand in some parts of the world, they might contract diseases elsewhere. Shaman says what we know for certain about climate change is that it will make it harder to predict where disease outbreaks will pop up.28. How does climate change affect the spread of disease according to Fair?A. By breaking animals’ habits.B. By increasing animals’ varieties.C. By promoting animals’ breeding.D. By changing animals’ livin g environment.29. What is the example of bats for in paragraph 3?A. Explaining the influence of Nipah virus.B. Proving the harm of bats to human beings.C. Showing the effects of climate change on disease.D. Presenting scientists’ early study a bout the cause of disease.30. What can we infer from Fair’s words in paragraph 4?A. Humans should give up studying animals.B. Past data can solve the problems in the future.C. Disease hot spots will disappear if animals die out.D. Frequent contact with animals can cause disease outbreaks.31. What could be the best title for the text?A. Climate Change and Disease SpilloverB. Animals’ Interaction with HumansD. Early Studies about Extreme WeatherC. Scientists’ Prediction for Disease Outb reaksDNew App Helps People Remember FacesLarge gatherings such as weddings and conferences can be sociallyoverwhelming. Pressure to learn people’s names only adds to the stress. Anew facial-recognition app could come to the rescue, but privacy expertsrecommend proceeding with caution.The app, called SocialRecall, connects names with faces via smartphone cameras and facial recognition, potentially avoiding the need for formal introductions. “It breaks downthese social barriers we all have when m eeting somebody,” says Barry Sandrew, who created the app and tested it at an event attended by about 1,000 people.After receiving an invitation to download SocialRecall from an event organizer, the user is asked to take two selfies and sign in via social media. At the event, the app is active within a previously defined geographical area. When a user points his or her phone camera at an attendee’s face, the app identifies the individual, displays the person’s name, and links to his or her social media profile. To protect privacy, it recognizes only those who have agreed to participate. And the app's creators say it automatically deletes users’ data after an event.Ann Cavoukian, a privacy expert who runs the Privacy by Design Center of Excellence praises the app’s creators for these protective measures. She cautions, however, that when people choose to share their personal information with the app, they should know that “there may be unintended consequences down the road with that information being used in another context that might come back to bite you.”The start-up has also developed a version of the app for individuals who suffer from prosopagnosia, or “face blindness,” a condition that prevents people from recognizing individuals they have met. To use this app, a person first acquires an image of someone’s face, from either the smartphone’s camera or a photograph, and then tags it with a name. When the camera spots that same face in real life, the previously entered information is displayed. The collec ted data are stored only on a user’s phone, according to the team behind the app.32. SocialRecall is used to ________.A. take photosB. identify peopleC. organize eventsD. make friends33. Paragraph 3 is mainly about ________.A. how the app worksB. how the app was createdC. what makes the app popularD. what people can do with the app34. SocialRecall helps people with prosopagnosia by ________.A. giving names to the photos kept in their smartphonesB. collecting information previously entered in the phoneC. providing the information of a person when they first meetD. showing the person’s information when it spots a stored face35. What can we learn about SocialRecall from the passage?A. It may put people’s p rivacy at risk.B. It has caused unintended consequences.C. It can prevent some communication disorders.D. It is praised by users for its protective measures.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。
