2. （多选题）右图是某物体做直线运动的v﹣t图象，由图象可得到的正确结论是（）A．t=1 s时，物体的加速度大小为1.0 m/s2B．t=5 s时，物体的加速度大小为0.75 m/s2C．第3 s内物体的位移大小为1.5 mD．物体在加速过程中的速度变化率比减速过程中的速度变化率大参考答案：BD【考点】匀变速直线运动的图像．【分析】速度时间图线的斜率表示物体的加速度大小，图线与时间轴所围成的面积表示物体的位移．加速度等于速度的变化率．由此分析答题．【解答】解：A、在0～2s内做匀加速直线运动，加速度保持不变，则t=1 s时，物体的加速度大小为a===1.5m/s2．故A错误．B、在3～5s内做匀减速直线运动，加速度保持不变，则t=5 s时，物体的加速度大小为|a|=||==0.75 m/s2，故B正确；C、物体在第3s内的位移x=3×1m=3m．故C错误．D、加速度等于速度的变化率，所以物体在加速过程中的速度变化率比减速过程中的速度变化率大，故D正确．故选：BD3. 关于电场线的说法，正确的是（）A．电场线的方向，就是电荷受力的方向。
B．正电荷只在电场力作用下一定沿电场线运动。
C．电场线越密的地方，同一电荷所受电场力越大。

It’ll enable us to focus more on our health.BIt goes without saying, but bears repeating, there are too many cats and dogs without homes. While there are countless shelters and rescue centers that exist, some potential pet owners look to pet shops to find their furry friends. All too often, however, these animals come from puppy and kitten mills (繁殖场) that treat the creatures in cruel ways. San Francisco, however, is doing their part to stop this abuse with pet store adoption. Officials recently voted to ban the sale of non-rescue dogs and cats in local shops.The effect is two-fold. One, it will stop the popularity of the large-scale mills, which are famous for the miserable conditions cats and does are kept in. Two, it will help facilitate the adoption of thousands of animals that are waiting for their forever homes in San Francisco shelters. District 4 Supervisor Katy Tang, who serves on the San Francisco Board of Supervisors, supported law-making on the ban. “Dogs andcats sold in pet stores often come from inhumane puppy and kitten mills that treat animals with no regard for their health or well-being”, she wrote on Facebook. In her message, she also called on the U. S. Agriculture Department to reinstate information on its website that documents these types of animal cruelty cases—it was removed earlier this month.San Francisco’s law-making is a victory for those concerned about animal rights, and they aren’t the first city to pass this type of measure. Los Angeles, San Diego, Chicago, Philadelphia, Boston, and Austin also have similar laws in place, with hopefully more places to follow suit.24. What happened to some dogs and cats before they got in the pet stores?A. They were treated cruelly.B. They were abandoned in streets.C. They received warm welcome.D. They were raised in shelters and rescue centers.25. Which of the following may Katy Tang agree with most?A. People should adopt the dogs and cats.B. Animals are too cruel to humans being.C. Government can choose to kill all the dogs and cats.D. It is not right to ban the sale of non-rescue dogs and cats in local shops.26. What does the underlined word “reinstate” in Paragraph 2 mean?A. updateB. replaceC. post againD. download27. What does the last paragraph mainly focus on?A. No Chinese city joins this type of movement.B. San Francisco is the last city to ban pet stores.C. Americans care about animals more than humans.D. More and more cities are involved in animal rights.CResearchers are now using three-dimensional, or 3D printing to create models of the human heart to help heart specialists. The heart doctors can use the models to better help patients before an operation.Surgeons regularly use digital images to explore the heart in close detail. But no two human hearts are alike. This led Matthew Bramlet, a children's heart expert, to create exact heart models from those images. He says the 3D models show information he cannot get in any other way. The 3D printed model adds a new dimension to heart surgery, allowing surgeons to see defects that might not be readily apparent in digital images.A 3D printer uses images from a digital display to create a physical model of a human heart. Pictures from medical tests like a CAT scan or an MRI scan are sent to a 3D printer to create a heart in a plaster or a clay form. The printer then constructs the heart, thin layer by thin layer. Dr. Bramlet says the model matches the real heart in every detail.Dr. Bramlet has built model hearts for different kinds of heart operations. All of the operations were successful. In his first case, digital images showed only one tiny hole in a baby's heart. But the 3D printed model showed several defects that the baby was born with. Dr. Bramlet says those defects could not be seen easily in the images. The heart surgeon was able to change the type of surgery for the patient based on the 3D model. He added that 3D heart models saved time during heart operations.Kathy Magliato is a heart surgeon. She welcomes the new technology. She says it could help her make better decisions before she operates on the hearts of her patients.Matthew Bramlet continues to research the technology. He is working with the National Institute of Health to build a 3D library that includes heart models and images that others can use.28. What’s the limitation of digital heart images?A. A lack of close details.B. Inability to display defects.C. Failure to show personal differences.D. Inaccuracy in the size of the child’s heart.29. What can the heart model created by 3D printing do?A. It can make defects readily apparent.B. It can conduct heart operations.C. It can replace the human heart.D. It can serve as an alternative to a CAT scan.30. What can we learn from the fourth paragraph?A. Dr.Bramlet wasted a lot of time in heart operations.B. 3D heart models have not been used in surgery at present.C. All of the operations were unsuccessful without 3D models.D. The model revealed defects previously unseen in the baby's heart.31. How does Kathy Magliato feel about the 3D printing?A. Supportive.B. Tolerant.C. Doubtful.D. Negative.DAstronauts on the International Space Station (ISS) may soon be able to turn their used forks and knives into tools and satellite parts.Tethers Unlimited Inc., an aerospace technology company, has developed a system that combines a waste recycling machine with a 3D printer.Astronauts will put waste items made of plastic into the recycling machine, called the Poistrusion Recycler. When they press a button, the Recycler will melt down the plastic and turn it into 3D filament (长丝).The filament will be used in a 3D printer on the ISS-called the Refabricator-to make tools, spare parts and satellite components.The waste will come from packaging materials, food containers, trays and eating utensils (器具) used on the ISS. Astronaut currently use disposable wet wipes to clean their food containers and utensils. The used wipes are stored as trash (垃圾), and replacement wipes must be sent up to the ISS on cargo missions.By recycling old food containers and utensils, astronauts will reduce the amount of trash they produce. To get rid of trash from the ISS, astronaut load it into empty cargo capsules (航天舱) and release it into space. The capsules burn up when they enter Earth’s atmosphere.Turning trash into useful new items will also help NASA save money because astronauts will need fewer supplies. It costs about $ 6,000 for every kilogram launched into orbit. These benefits will be even more important for longer missions in the future-such as the two-year journey to Mars. Astronauts will be able to recycle old waste materials into new tools and parts as they need them.Tethers have successfully tested the systems in its laboratory. They will test it on the ISS in late 2018. The company is also developing a version of the system for use here on Earth.32. What material are the forks and knives for astronauts made of?A. Gold.B. IronC. Plastic.D. Wood.33. At present, the astronauts mainly get supplies by .A. 3D printersB. reusing the old onesC. collecting from the spaceD. the capsules launched from the earth34. What can the new technology help the astronauts do?A. Reuse the trash.B. Send the trash to Mars.C. Take the trash to the earth.D. Load the trash into empty capsules and throw it away.35. What is the biggest benefit of the new technology mentioned in the text?A. It can save some space for the ISS.B. It can gave more time for the astronauts.C. It can provide more conditions to explore space.D. It can help to reduce the journey from Earth to Mars.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。
