手惰市安逸阳光实验学校Unit 4 EarthquakesⅠ.阅读理解(建议用时16′)A[2017·惠州调研]Humans have been keeping animals as pets for tens of thousands of years, but Dr Jean－Loup Rault, an animal scientist at the University of Melbourne in Australia, believes new companions are coming: robot pets.“Technology is moving very fast，” Rault told ABC News, “The Tamagotchi in the early 1990s was really the first robotic pet, and now Sony and other big companies have improved them a lot.”This may not sit_well_with pet lovers. After all, who would choose a plastic W1 toy over a lovely puppy? But Rault argues that the robotic kind has a lot going for it：“You don't have to feed it, you don't have to walk it, it won't make a mess W2 in your house, and you can go on a holiday without feeling guilty.” The technology also benefits those who are allergic to P1 pets, short on space, or fearful of real animals.It's not clear whether robot pets can replace real ones. But studies do suggest that we can bond with these smart W3 machines. People give their cars names and kids give their toy animals life stories. It's the same with robots. When Sony stopped its repair service for its robot dog Aibo in March 2014, owners in Japan held funerals.As an animal welfare researcher, Rault is concerned about P2 how robotic pets could affect our attitudes W4towards live animals. “If we become used to a robotic companion that doesn't need food, water or exercises, perhaps it will change how humans care about other living beings，” he said.So are dogs and cats a thing of the past, as Rault predicts? For those who grew up with living and breathing pets, the mechanical kind might not do. But for our next generation W5 who are in constant touch with smart technology, a future in which lovely pets needn't have a heartbeat might not be a far－fetched dream.篇章导读：随着科技的发展，一种新的宠物即将出现：机器人宠物。

手惰市安逸阳光实验学校Unit 4 Earthquakes(60分钟79分)Part A一、阅读理解(共7小题;每小题2分,满分14分)AScientists at UC Berkeley released a video showing an earthquake early-warning system that sent an alert before the magnitude-6.0 Napa earthquake on Sunday morning.Officials said the system provided an alert 10 seconds before the quake was felt.California is working to complete a statewide system,which could be completed in the next few years.Once fully developed,the system could give downtown Los Angeles 40 to 50 seconds of war ning that the “Big One” was headed from the San Andreas fault,giving time for elevators to stop at the next floor and open up,firefighters to open up garage doors,high-speed trains to slow down to avoid derailment and surgeons to take the scalpel(手术刀) out of a patient.A lack of funds,however,has slowed the system’s progress.The system works because while earthquakes travel at the speed of sound,sensors that initially detect the shaking near the epicenter of a quake can send a message faster—at the speed of light—to warn residents farther away that the quake is coming.Rep.Adam Schiff (D-Burbank) said the successful test showed the need for the system.“While this was not the ‘big one’,we need to be prepared to save lives and protect vital infrastructure(基础设施)—even a few seconds of warning will allow people to seek cover,automatically slow or stop trains,pause surgeries and more,” he said in a statement.1.It will take a few years to finish the statewide earthquakeearly-warning system because .A.it’s a hard workB.there’s no enough moneyC.it’s a large systemD.there’s no enough workers2.Which can be inferred from the passage?A.The system can send an alert before an earthquake starts.B.The system works based on the difference of the speed between sound and light.C.Even warning a few seconds ahead can give time to save many lives and vital infrastructure.D.After the system is completed,people will not be afraid of earthquakes in California.3.The word “while” in the last paragraph means .A.thoughB.howeverC.andD.because【文章大意】本文为说明文,主要介绍了加州的地震预警系统。
