When he finished medical and became a doctor, Adams his own hospital, called “the Gusundheit Institute”，together with some other doctors.

三、阅读理解（本题共15小题；每小题2分，满分30分）
请认真阅读下列短文，从短文后各题所给的A、B、C、D四个选项中，选出最佳选项，并在答题卡上将该项涂黑。 A In English, people use many expressions with the word dog. People in Britain and America love their dogs and treat them well. They take their dogs for walks, let them play outside and give them good food and medical care．However, dogs without owners to care for them lead a different kind of 1ife．The expression, to lead a dog’s life，means living an unhappy life.
Some people say we live in a dog-eat-dog world. That means many people are competing for the same thing，like good jobs．They say that to be successful, a person has to work like a dog. Such work can make people dogtired. And the situation will be even worse if they become sick as a dog. Sometimes we should let a sleeping dogs lie, which means we’d better not trouble a person who is likely to cause problems. And if someone says you’re a lucky dog, he is just saying you are very lucky.
Very often, people say every dog has its day. This means that every person enjoys a successful period during his or her life. To achieve one’s goal, people often have to learn new skills. Yet, some people say that you can never teach an old dog new tricks. They believe that older people do not like to learn new things and will not change the way they do things.
Dog expressions are also used to describe the weather. The dog days of summer are the hottest days of the year．A rainstorm may cool the weather. But we do not want it to rain too hard. We do not want it to rain cats and dogs. 31. According to what have read above, working too hard can make people________.
A. let a sleeping dog lie
B. become a lucky dog D. work like a dog C. live in a dog-eat-dog world
32. What can we learn from the passage?
A. It may difficult for the young to learn new skills. B. Dogs play an important part in language and culture. C. We can be successful if we learn from our mistakes. D. Dogs like the hottest days in summer very much. 33. If we say a person lives a dog’s life, he might be________.
A. a student who does quite well in English
B. a baby that is well taken care of by its mother
C. a person who has endless work to do
D. an old person who refuses to accept new things
B Starting from my second year of primary school, there was one event I hated every
year: the piano recital(独唱会). I didn’t want to practice a boring piece of music and was afraid to perform in front of strangers. Each year I would ask my father if I could
clear the recital “just this once”. And he would say something about building self-confidence and working toward a goal.
So I was very satisfied when I stood in church(教堂) and watched my father play the piano during his very first recital. My father wanted to play music when he was small. But his mother couldn’t afford lessons. Three years ago, when he retired, he asked the church music director, Charles, to take him as a student. Just before the recital, Charles told me my dad was playing “the best I’ve ever seen him.”
For a moment after my father sat down at the keyboard, he simply stared down at(盯得……不敢对视) his fingers. I wondered whether he would even begin. But then Aram Khachaturian’s Melody began. It seemed that my father was so focused on the music that he didn’t realize we were there.
My dad made it through Melody and then through another song. Although he didn’t have much skill, he made up for it in feeling.
My 11-year-old son Jeff was there. “So what did you think about your granddad?” I asked Jeff later. “He was great,” Jeff replied.
My father may not have reached his height musically, but in his grandson’s eyes, he’s at the top of the mountain. 34. From the first paragraph, we know the writer A. practiced the piano every day B. was confident at piano recitals
C. didn’t like to play the piano at all D. was always working toward his goal
35. Which is NOT true about the writer’s father?
A. He was poor when he was a child. B. He gave a piano recital the year he retired. C. The music teacher was proud of him. D. He had learned the piano for three years.
36. Why did people like the performance of the writer’s father?
A. Because he practiced hard. B. Because he was an old learner. C. Because he played with his feelings.
D. Because he communicated with people. 37. What does the story tell us?
A. Children should respect parents’ decisions.
B. Learning an instrument is easy for old people.
C. Never give up on your dreams no matter your age.
D. Skills for playing an instrument are not very important.
C
On March 14, math and science lovers around the world celebrated a special day: Pi Day.
Pi is equal to about 3.14, but the number goes on endlessly. It is sometimes written in Greek, π. With the help of computers, mathematicians have been able to calculate(计算) pi
out to over a trillion (万亿) decimal (小数的) places, but there is still no end to the number.
Pi Day is celebrated around the world on March 14, since how we write this date, 3/14, looks just like the number pi.
For some people, the appeal(感染力) of Pi Day goes far beyond math and science. Pi shows up throughout popular culture. You can see it in movies, comics, music and more. “In modern movies, any time the filmmaker wants to produce a sense of mystery(神秘), often the symbol pi is used,” says David Blatner, Jewish American writer of The Joy of Pi.
People also love trying to memorize the digits (数字) of pi and competing against others to see who can remember the most. Many teachers hold class contests to see how many numbers their students can memorize. The Guinness World Record for reciting the most digits of pi is held by Lü Chao of China, who successfully recited pi out to nearly 67,890 decimal places. Above all, Pi Day is about having fun with the number. People celebrate Pi Day by eating or throwing pie and with fun pi-related games and activities. This year, Princeton, New Jersey, held a birthday party for Albert Einstein whose birthday also falls on March 14. There was also a “Walk a Pi Event” where people walked 3.14 miles together. Just like the number itself, the possibilities for Pi Day are truly endless. 38. The following about Pi Day is true EXCEPT A. it’s on March 14
B. it’s a day just for scientists D. Pi’s Greek form is π B. not clear to the understanding D. of great help B. represent the subject of math D. describe something mysterious B. Activities about pi in class. D. Albert Einstein’s birthday.
D Have you ever experienced the feeling of falling as you start to fall asleep?
Sometimes you may come to realize this feeling. If so, don’t worry. Many people have
felt the same thing.
In fact, these muscle twitches (肌肉抽搐) in the arms, legs or other parts of the
body are called hypnic jerks (入睡抽动) or sleep starts. And they are very common. Up
to 70 percent of people experience them sometimes, Huffington Post reported. But what
causes it?
There are some theories(理论). Some scientists believe that the feeling of falling comes from the body relaxing itself, especially
if
the person is anxious or unable to get comfortable. As you’re about to sleep, your
C. Pi is equal to about 3.14 A. attractive C. exciting A. represent a long number 39. What does the underlined word “” in Paragraph 2 mean? 40. In modern movies, the symbol pi is often used to ________. C. describe something boring A. Fun activities on Pi Day. C. Walk a Pi Event. 41. What does the last paragraph talk about?

（2）若电源电压是9V，闭合开关S1和

（3）若换一个电压未知但不变的电源，闭合开关S1断开开关S2，滑动变阻器的滑片从一处滑到另一处时，电压表的示数由5V变化到1V，电流表的示数变化了0.4A，则R0的阻值是多少？
34、(8分)在“测量小灯泡电功率”的实验中，电源电压恒定为6V，小灯泡的额定电压为
2.5V，正常发光时的电阻约为10Ω，所用滑动变阻器的最大阻值约为40Ω。
⑴请用笔画线代替导线把甲图中未完成的实物电路连接完整；
⑵同学们进行试触时，发现小灯泡不发光，电流表无示数，电压表有示数，则电路中发生的故障可能是_____________(选填“小灯泡断路”、“小灯泡短路”或“滑动变阻器处断路”)；
⑶排除故障后，闭合开关又发现小灯泡不亮，但电流表有示数，接下来应进行的操作是________
A．更换小灯泡 B.检查开关是否闭合
C．移动滑动变阻器滑片 D.检查电压表是否断路
⑷某次中实验中，同学们看到电压表示数为1.8V，要使灯泡L正常发光应向_____(选填“A” 或“B” )端移动滑片P，同时视线应注意观察_________（选填“电流表”或“电压表”）示数，当灯泡正常发光时，电流表的示数如图乙所示，则小灯泡的额定电功率是________W；
⑸某同学还想探究电流与电阻的关系，于是将甲图中的小灯泡换成定值电阻R，并使电压表的示数始终保持2V不变，多次更换阻值不同的定值电阻R，记录各次电流表的示数，在不更换其他器材的情况下，为了能够完成实验，他更换的定值电阻R的阻值不能大于____Ω。
35、（6分）探究篮球反弹性能的强弱与哪些因索有关?
【猜想与假设】猜想一：可能与篮球的材质有关；
猜想二：可能与篮球的充气情况有关；
【制定计划与设计实验】
在探究猪想一时，我们只选择材质不同、其他因素都相同的篮球，设计了以下实验方案． 方案一：其他条件都相同，用力向下拍不同的篮球，观察比较它们反弹后的高度； 方案二：其他条件都相同，将不同的篮球从同一高度自由下落．观察比较它们反弹后的
高度
方案三：其他条件都相同，使不同的篮球反弹到相同的高度．观察比较它们所需自由下
落高度．
【评估与交流】
(1)按照方案一探究，其不足之处是___________________________________________；
(2)按照方案二探究．篮球反弹后的高度越高，反弹性能就越_______
；像这种用反弹的
