1.法国科学家拉普拉斯曾说过:“认识一位巨人的研究方法对于科学的进步并不比发现本身有更少的用处……”。

在物理学的重大发现中科学家们创造出了许多物理学方法,如观察、实验、建立模型、物理类比和物理假说等方法。

其中物理假说,是根据一定的科学事实和科学理论对研究的问题提出假说性的看法或说明,以下属于物理假说的是 A .安培分子电流B .麦克斯韦电磁场理论C .爱因斯坦光子说D .法拉第发现电磁感应现象2. 爱因斯坦由光电效应的实验规律提出了光子说,以下对光电效应的解释,正确的是A .金属内的每个电子可以吸收一个或一个以上的光子,当它积累的动能足够大时,就能逸出金属B .如果入射光子的能量小于金属表面的电子克服原子核的引力逸出时需要做的最小功,但只要照射时间足够长光电效应也能发生C .发生光电效应时,入射光越强,光子的能量就越大,光电子的最大初动能就越大D .由于不同金属的逸出功是不相同的,因此使不同金属产生光电效应的入射光的最低频率也不相同3. 如图所示,四个质量、形状相同的斜面体放在粗糙的水平面上,将四个质量相同的物块放在斜面顶端,因物块与斜面的摩擦力不同,四个物块运动情况不同,放上A 物块后A 物块匀加速下滑,B 物块获一初速度后匀速下滑,C 物块获一初速度后匀减速下滑,放上D 物块后D 物块静止在斜面上,四个斜面体均保持静止,四种情况下斜面体对地面的压力依次为F 1、F 2、F 3、F 4,则它们的大小关系是A .F 1=F 2=F 3=F 4B .F 1>F 2>F 3>F 4C .F 1<F 2=F 4<F 3D .F 1=F 3<F 2<F 4 4. 加速度计是测定物体加速度的仪器,如图所示为应变式加速度计的结构示意图。

Perhaps I am Courageous, but that's because I've had some inspiring teachers. I'll tell you about one of them. Many years ago, when I worked 16 a volunteer at Stanford Hospital, I got to know a little girl named Liza 17 was suffering from a rare and serious disease, Her only chance of 15 (recover) appeared to be a blood transfusion (输血) from 19 five-year-old brother, who 20 (survive) the same disease and developed the antibodies needed to combat the illness. The doctor explained the situation to her little brother, and asked the boy 21 he would be willing to give his blood to his sister. I saw him hesitate for a moment 22 taking a deep breath and saying, "Yes, I'll do it if it will save Liza."As the transfusion progressed, he lay in a bed next to his sister, 23 (smile). But then his face grew pale and his smile faded. He looked at the doctor and asked with 24 trembling voice, "Will I start to die fight away?"Being young, the boy had misunderstood the doctor. He thought he was going to have to give her 25 his blood.Ⅱ.阅读(共两节,满分50分)第—节阅读理解(共20小题;每小题2分,满分40分)阅读下列短文,从每题所给的A、B、C和D项中,选出最佳选项,并在答题卡上将该项涂黑。

AAfter our early morning wake-up, we are still a couple ofhours away from the overlooks.It is pitch black.I can feel theheavy humid fog left behind my last night's rain. This is whythe tour memo listed "flashlight". Unfortunately; the majorityof our hiking party of nine must have missed the memo, so wehave only four flashlights between us.An hoar later,we are on the trail. It is dark, foggy, wet and the rocks are alippery.We alternate places between the flashlights "haves" and "have-nots". As we march, the only voices heard are from the "haves": "Step up, step down, watch out for the rock on your left."We reach Intipunku with only 15 minutes to spare. The view at sunrise is not what we were told in the travel brochures. Three feet in front of our faces is a white substance called "fog".As we walk towards the Machu Picchu ruins, my anticipation is mounting. When will the fog lift? Slowly, as if someone is cranking up a curtain, Huayna Picchu begins to appear,overlooking Machu Picchu. First there are fleeting glimpses, and then finally, there is, in its full splendor.When I envisioned going to Machu Picchu, I always thought of mysterious ruins and the famous postcard picture looking toward Huayna Picchu. But there is more to this man-made / natural wonder of the World. It is the adventure of getting there. I knew I wanted to experience the feel of the Inca culture and the energy of this sacred valley, I also knew I didn't want to take the train, but needed to hike. Depending on your starting point,the Inca Trail is 25 to 33miles of semi-arid desert, breathless mountain passes and stunning tropical cloud forest. Our hike took us four nights and 25 miles to finish.Our local guide MaurO keeps telling us "no worries, the hike is 90 percent mental and only10 percent physical. "I am not convinced that the physical percentage is correct, but I definitely become more and more excited as we are now getting closer to Machu Picchu.By getting myself into good shape, running 20 miles and hiking a 500-foot-high hill five to seven times per week before I left for Peru, I was able to enjoy the beauty of the hike and not worry much about aching muscles and lungs.26. About flashlights, which of the following statements is true?A. The local guide had asked them to take flashlights for the hike.B. They had taken enough flashlights for the hike.C. Before they got to Intipunku, they depended a lot on their flashlights.D. They used flashlights all the time.27. Put the following events into the right order.a. They reached Intipunku,b. They read the travel brochures.c. They walked on the trail in the dark.d. They advanced to get closer to Maehu Picchu.e. They enjoyed the splendor of Huayna Picchu.A. ebadeB. bacdeC. abcedD. bcaed28. What does the underlined word "anticipation" in Paragraph Four mean?A. expectationB. excitementC. disappointmentD. enthusiasm29. What can NOT be inferred from the text?A. The writer made good preparation for the tour.B. The Inca Trail took them four nights.C. Machu Picchu is in the country of Peru.D. They reached Intipunku ahead of time.30. According to the writer, what attracted him most in the tour?A. Mysterious ruins.B. The famous post-card picture.C. The hiking.D. The Inca culture.BElectric ears are dirty.In fact, not only are they dirty, they might even be more dirty than their gasoline-powered cousins.People in California love to talk about "zero-emissions vehicles", but people in California seem to be clueless about where electricity comes from. Power plants mostly use fire to make it. Aside from the new folks who have their roofs covered with solar cells, we get our electricity from generators. Generators are fueled by something---usually coal, oil,but also by heat generated in nuclear power plants. There are a few wind farms and geothermal plants as well, but by far we get electricity mainly by burning something.In other words, those "zero-emissions" cars are likely coal-burning cars. It's just because the coal is burned somewhere else that it looks clean. It is not. It's as if the California Greens are. covering their eyes---"If I can't see it, it's not happening." Gasoline is an incredibly efficient way to power a vehicle; a gallon of gas has a lot of energy in it.But when you take that gas (or another fuel) and first use it to make electricity, you waste a nice part of that energy, mostly in the form of wasted heat---at the generator, through the transmission lines, etc.A gallon of gas may propel your car 25 miles. But the electricity you get from that gallon of gas won't get you nearly as far---so electric cars bum more fuel than gas-powered ones. If ourelectricity came mostly from nukes; or geothermal,or hydro, or solar, or wind,then an electric car truly would be clean. But for political, technical,and economic reasons,we don't use much of those energy sources.In addition,electric cars' batteries which are poisonous for a long time will eventually end up in a landfill.And finally, When cars are the polluters, the pollution is spread across all the roads. When it's a power plant, though, all the junk is in one place. Nature is very good at cleaning up when things are too concentrated, but it takes a lot longer when all the garbage is in one spot.31. What does "clueless" mean in paragraph 2?A. People are seeing the California Greens everywhere.B. People in California love to talk about zero-emissions vehicles.C. People in California love to have their roofs covered with solar cells.D. People there have no idea that so far electricity mainly comes from burningcoal, oil,etc.32. What is the main idea of the passage?A. Electric cars are not clean at allB. Electric cars are better than gasoline-powered ones.C. People cast doubts on electric cars' batteries.D. Gasoline is an efficient way to powera vehicle.33. The electricity we get from a gallon of gas may make our ear runA. not less than 25 milesB. more than 25 milesC. no more than 25 milesD. not more than 25 miles34. According to the passage, electric cars .A. do not burn fuel and more environmentally-friendlyB. are toxic because it is difficult for nature to clean it up when theirbatteries are buried in one spot.C. are very good at cleaning up when things are not too concentratedD. are poisonous for a long time and will eventually end up in a landfill35. It can be inferred from the passage thatA. being green is good and should be encouraged in communicationB. electric cars are not clean in that we get electricity mainly by burningsomethingC. zero-emissions vehicles should be chosen to protect our environmentD. electric cars are now the dominant vehicle compared with gasoline-poweredcousinsCDear Michelle:Why can't my daughter manage her life better? She is 17 and an honor student, but she seems to be wasting her life away with a boyfriend who is holding her back.He consumes every waking, minute of her precious time and smooth-talks her as well.His goal is to get her to agree to go to the college of his choice, not her choice, and because his grades are lower, his choice will be limited.I feel like I want to rescue her, but she pushes me away and shuts me out. She has only brought us pride and joy; and now this! Help!A worried motherDear Mother of a 17-year-old Girl:Hmmmmm. What's the matter with kids today? Remember that song from "Bye Bye Birdie"?Well if you do not, let me fill you in about teenagers and their life-management skills.Do not expect too much too soon because at the ripe age of 17, life-management is not within their reach, not should it be.Life experience creates both the conditions and the skills for management, and if management went before experiene, there would be tittle of it.Your daughter is an honor student for good reasons. She is smart, studies withintelligence and you have given her good Values.When the time comes for her to apply for college, and she visit the ones that were specifically desigened for student the top of their grade, she will most likely break away from her boyfriend's influenee.It is rare for an honor student to change the path of their academic career for puppy love. That being said, them might be some adoldscent wisdom in her behavior after all.Perhaps she is choosing to worry you, her parents, for unconscious reasons.
