【题文】14.奥斯特发现了电流能在周围产生磁场，法拉第认为磁也一定能生电，并进行了大量的实验。
图中环形物体是法拉第使用过的线圈，A、B两线圈绕在同一个铁环上，A与直流电源连接，B与灵敏电流表连接。
实验时未发现电流表指针偏转，即没有“磁生电”，其原因是A.线圈A中的电流较小，产生的磁场不够强B.线圈B中产生的电流很小，电流表指针偏转不了C.线圈A中的电流是恒定电流.不会产生磁场D.线圈A中的电流是恒定电流，产生稳恒磁场【知识点】法拉第电磁感应定律．L2【答案解析】D 解析：闭合与断开开关S的瞬间，A线圈中的电流发生了变化，穿过线圈B的磁通量发生变化，电流表G中产生感应电流．闭合开关S 后，穿过线圈B的磁通量都不发生变化，电流表G中没有感应电流，感应电流只出现在磁通量变化的暂态过程中，这是在法拉第研究电磁感应现象的过程中中的瓶颈所在．故选项D符合题意．故选：D．【思路点拨】电流表与线圈B构成闭合电路，当线圈中磁通量发生变化时，出导致线圈中产生感应电动势，从而可出现感应电流．感应电流只出现在磁通量变化的暂态过程中．法拉第研究电磁感应现象的过程其本质是发现感应电流产生的条件的过程．由于感应电流仅仅在线圈中的磁通量发生变化的过程中出现，磁通量不变时则没有感应电流，感应电流只出现在磁通量变化的暂态过程，所以感应电流不容易被发现．【题文】15。

It's difficult for others to understand yourgoals.Well, 1 certainly don't think you're crazy. In fact, every traveler I know would agree that you're only crazy if you decide not to go after your goals in life.I started traveling back in 1999, shortly after graduating from university. My plan was to backpack around Southeast Asia for three months and then return to the US to becomea sports agent. However, just one week into that trip, I realized that tbree months of travel simply wasn't enough.The only problem was that I had less than $1,500 to my name. Fast forward lo today... Over the past 15 years, 1 have discovered, and taken advantage of, endless opportunities that have allowed me to continuously live, travel, study and earn money in over 85 countries.

Aaron Puzey had been on his exercise bike for half an hour a day for years when he decided to look for a way to make it a bit more fun.With virtual reality technology widely available nowadays, all be needed to do was find a way of applying it to his needs. So he set out to build an app (应用程序）for the Samsung Galaxy Gear VR headset (头戴式视图器）which would allow him to hook it up to Google Street view and make it seem like he’s cycling through different real-life locations. Building the app to download the 3D data from Street View and make it viewable in the VR headset was the toughest part of his project. Other than that, all heneeded to do was tape a Bluetooth monitor to his exercise bike. Although the quality of the images sometimes leaves a lot to be desired，leaving complex scenes like trees looking like a mess，Aaron has been having a lot of fun on his journey.Aaron's project is obviously no substitute (替代品〉for real outdoor cycling as it Lacks things like the wind blowing in your face or the pain of battling an uphill climb, bul it has given him a goal, as well as the chance to take in the beauty of places he might have otherwise never seen. It definitely beats staring at a wall or at the TV for 30 minutes, anyway.Obviously, Aaron’s setup theoretically allows him to ride a b ike anywhere around the world. He says he ba6 always wanted to see Japan, so once his ride comes to an end, he plans to start another one across the Land of the Rising Sun.8. Why did Aaron Puzey build the app?A. To invent a new kind of bicycle.B. To participate in a competition.C. To satisfy the needs of the public.D.To add fun to his exercise bike routine*9. Which of the fallowing can best describe Aaron Puxey?A. Creative.B. Ambitious.C. Funny.D. Boring.10. What was the challenge for Puzey in his project?A. Changing the 3D data into pictures.B.

Cycling Across the World at HomeB. The Lazy Man and His Crazy IdeaC. A New Way of Cycling Without EffortD. A Substitute for Real Outdoor CyclingIf you're still of the belief thaJ mental health conditions aren，t as serious as physical ones，a new report will open your eyes.The United States spent about $201 billion on mental illness in 2013, according to the new analysis published in the journal Health Affairs. That makes it the costliest medical condition in the country. Heart conditions were the second costliest condition, falling far behind menial disorders at $147 billion. Trauma(外伤）and injury was third at $143 billion.“One key finding of this study is the degree to which spending on mental health disorders in 2013 topped those on all other medical conditions, including heart conditions, trauma, and cancer. Researcher Charles Roehrig wrote in the study's conclusion.Just a decade ago, heart conditions outweighed mentd disorders. Health care costs on heart Problems were about $105 Million in 1996, with mental disordere coming in second at $79 billion.The findings are just another example of how important it is to recognize mental illness as a widespread public health issue. Nearly one in four people will experience a mental health condition at some point in his or her life. Despite this fact, though, there'sstill a lack of sensitivity and understanding in society—and even the medical community—when it comes to mental disorders.Research shows discrimination involved in mental health. Negative thoughts surrounding mental illness often prevent people from seeking treatment, which can have serious consequences.Data also suggests that not paying attention to mental illness can affeci a company 's bottom line. Serious mental illnesses result in about $193 billion in lost earnings per year.Lastly, the cost of mental health issues extends beyond a dollar sign, but perhaps the shocking figure in the report will finally serve as a wakeup call for those who believe psychological (心理的）conditions aren't real issues. In other words, can we please take mental illness seriously now?12. What does the underlined word “That” in Paragraph 2 refer to?A. The new analysis.B. Mental illness.C.$201 billion.D. The journal Health Affairs.13. How much more is spent on mental disorders in 2013 compared with 1996?A.$54 billion.B.$96 billion.C.$122 billion.D.$143 billion.14. What is one reason why people hesitate to receive mental treatment?A. Psychological doctors charge too much.B. They aren't aware of their mental illness.C. They don't believe in doctors medical skills.D. They are afraid of being looked down upon.15. What is the author5 s purpose in writing this passage?A. To show harmful effects of mental disorders.B. To raise people's awareness of mental health.C.To prove the importance of public health issue.D.To remind people to have mental examinations.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，并在答题卡上将该项涂黑。

That makes it the costliest medical condition in the country. Heart conditions were the second costliest condition, falling far behind menial disorders at $147 billion. Trauma(外伤）and injury was third at $143 billion.“One key finding of this study is the degree to which spending on mental health disorders in 2013 topped those on all other medical conditions, including heart conditions, trauma, and cancer. Researcher Charles Roehrig wrote in the study's conclusion.Just a decade ago, heart conditions outweighed mentd disorders. Health care costs on heart Problems were about $105 Million in 1996, with mental disordere coming in second at $79 billion. The findings are just another example of how important it is to recognize mental illness as a widespread public health issue. Nearly one in four people will experience a mental health condition at some point in his or her life. Despite this fact, though, there's still a lack of sensitivity and understanding in society—and even the medical community—when it comes to mental disorders.Research shows discrimination involved in mental health. Negative thoughts surrounding mental illness often prevent people from seeking treatment, which can have serious consequences. Data also suggests that not paying attention to mental illness can affeci a company 's bottom line. Serious mental illnesses result in about $193 billion in lost earnings per year. Lastly, the cost of mental health issues extends beyond a dollar sign, but perhaps the shocking figure in the report will finally serve as a wakeup call for those who believe psychological (心理的）conditions aren't real issues. In other words, can we please take mental illness seriously now?12. What does the underlined word “That” in Paragraph 2 refer to?A. The new analysis.B. Mental illness.C.$201 billion.D.

What is one reason why people hesitate to receive mental treatment?A. Psychological doctors charge too much.B. They aren't aware of their mental illness.C. They don't believe in doctors medical skills.D. They are afraid of being looked down upon.15. What is the author5 s purpose in writing this passage?A. To show harmful effects of mental disorders.B.
