21(1)如图7所示,是多用电表示意图。某同学想用此多用电表检测一下家庭电路的电压,他应该将多用电表的挡位选择旋钮放在           位置。图7乙中示数即为他的测量值,则他所测家庭电路的电压为           V。

 

 

 

 

 

 

 

 

 

 

(2)用如图8所示的实验装置验证机械能守恒定律。实验所用的电源为学生电源,能输出电压为6V的交流电和直流电。重锤从高处由静止开始落下,重锤上拖着的纸带通过打点计时器打出一系列的点,对纸带上的点的痕迹进行测量,即可验证机械能守恒定律。

①下列列举了该实验的几个操作步骤:

A.按照图示的装置安装器件;

B.将打点计时器接到电源的6V直流输出端上;

C.用天平测量出重锤的质量;

D.释放悬挂纸带的夹子,同时接通电源开关打出一条纸带;

E.测量打出的纸带上某些点之间的距离;

F.根据测量的结果计算重锤下落过程中减少的重力势能是否等于增加的动能。

指出其中没有必要进行的或者操作不恰当的步骤,将其选项对应的字母填在下面的空行内,并说明其原因。

答:                                                                     

                                                                            

                                                                            

 

②如图9所示。根据打出的纸带,选取纸带上打出的的连续五个点A、B、C、D、E,测出A点距起始点O的距离为s0,点A、C间的距离为s1 ,点C、E间的距离为s2,使用交流电的频率为f,则根据这些条件可以计算出打C点时重锤的速度vc=          。还可以计算出重锤下落的加速度a=            。

 

 

 

 

 

根据纸带算出的相关各点的速度v,量出下落的距离h,则以v2为纵轴,以h为横轴,根据实验数据绘出的v2-h图线应是图10中的            

 

 

 

 

 

 

④在验证机械能守恒定律的实验中发现,重锤减小的重力势能总是大于重锤动能的增加,其原因主要是因为在重锤下落过程存在着阻力的作用,可以通过该实验装置测定该阻力的大小。若已知当地重力加速度为g,还需要测量的物理量是              。则重锤在下落过程中受到的平均阻力大小F=            。

 

22.如图11所示,水平绝缘粗糙的轨道AB与处于竖直平面内的半圆形绝缘光滑轨道BC平滑连接,半圆形轨道的半径R=0.40m。在轨道所在空间存在水平向右的匀强电场,电场线与轨道所在的平面平行,电场强度E=1.0×104 N/C。现有一电荷量q=+1.0×10-4C,质量m=0.10kg的带电体(可视为质点),在水平轨道上的P点释放由静止释放,带电体恰好能通过半圆形轨道的最高点C,然后落至水平轨道上的D点。取g=10m/s2。求:

(1)带电体在圆形轨道C点的速度大小;

(2)带电体运动到圆形轨道B点时对圆形轨道的压力大小;

(3)带电体在从A开始运动到落至D点的过程中的最大动能。

 

 

 

 

23.光子具有能量,也具有动量。光照射到物体表面时,会对物体产生压强,这就是“光压”。光压的产生机理如同气体压强:大量气体分子与器壁的频繁碰撞产生了持续均匀的压力,器壁在单位面积上受到的压力就是气体的压强。设太阳光每个光子的平均能量为E,太阳光垂直照射地球表面时,在单位面积上的辐射功率为P0。已知光速为c,则光子的动量为E/c。求:

(1)若太阳光垂直照射在地球表面,试计算时间t内照射到地球表面上半径为r的圆形区域内光子的总动量。

(2)一般情况下,太阳光照射到物体表面时,一部分会被反射,还有一部分被吸收。当物体表面的反射系数为ρ时,则在每秒内照射到物体表面的全部n个光子中,有(1-ρ)n个被吸收而ρn个被反射。若太阳光垂直照射在地球表面反射系数为ρ、半径为r的某圆形区域内,则在时间t内照射到此区域的光子的总动量的变化量是多少?

(3)在第(2)问中太阳光在圆形区域表面产生的光压(用I表示光压)是多少?

 

24.图12虚线框内为某种电磁缓冲车的结构示意图,在缓冲车的底板上沿车的轴线固定有两个足够长的平行绝缘光滑导轨PQ、MN,在缓冲车的底部还安装有电磁铁(图中未画出),能产生垂直于导轨平面的匀强磁场,磁场的磁感应强度为B。在缓冲车的PQ、MN导轨内有一个由高强度材料制成的缓冲滑块K,滑块K可以在导轨上无摩擦地滑动,在滑块K上绕有闭合矩形线圈abcd,线圈的总电阻为R,匝数为n,ab的边长为L。缓冲车的质量为m1(不含滑块K的质量),滑块K的质量为m2。为保证安全,要求缓冲车厢能够承受的最大水平力(磁场力)为Fm,设缓冲车在光滑的水平面上运动。

(1)如果缓冲车以速度v0与障碍物碰撞后滑块K立即停下,则滑块K线圈中ab边受到磁场力的大小是多少;

(2)如果缓冲车与障碍物碰撞后,滑块K立即停下,为保证安全,缓冲车行驶的速度应满足什么条件;

(3)如果缓冲车以速度v匀速行驶时,在它前进的方向上有一个质量为m3的静止物体C,滑块K与物体C相撞后粘在一起,碰撞时间极短。求滑块K与物体C碰撞结束时缓冲车受到的水平磁场力的大小;

       In Glasgow, Scotland, a young lady, like a lot of  teens today, got tired of home. The daughter objected to her family’s    21     lifestyle and said, “I don’t want your God. I am leaving!”

       She left home. Before long, she was disappointed and unable to find a job, so she took to the streets to do everything she could to   22   money. Many years passed by, her father died, her mother grew    23   , and the daughter became more and more entrenched (不易改的) in her way of life.

       No contact was made between mother and daughter during these years. The mother, having    24     her daughter’s whereabouts, went to the poor part of the city in   25    of her daughter. She stopped at each of the rescue missions with a simple    26   . “Would you allow me to    27    this picture?” It was a picture of the smiling, gray-haired mother with a handwritten    28    at the bottom, “I love you still…come home!”

       One day the daughter wandered into a rescue mission for a hot meal. She sat    29     listening to the service, all the while letting her    30    wander over to the bulletin board. There she saw the picture and thought, could that be my mother?

       She couldn’t    31    until the service was over. She stood and went to look. It was her mother, and there were those words, “I love you still…come home!”   32    she stood in front of the picture, she wept. It was too     33    to be true.

       It was night, but she was so     34    by the message that she started walking home.    35     the time she arrived it was early in the morning. She was afraid and    36     her way timidly. As she knocked, the door    37     open on its own. She thought someone must have broken into the house. Concerned for her mother’s    38   , the young woman ran to the bedroom and shook her mother awake and said, “It’s me! It’s me! I’m home!”

       The mother couldn’t believe her eyes. They fell into each other’s arms. The daughter said, “I was so worried and    39     someone had broken in.” The mother replied gently, “No, dear. From the day you left, that door has never been    40   .”

第二部分:阅读理解(第一节20小题,第二节5小题,每题2分,满分50分)

第一节:阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项,并在答题卡上将该项涂黑。

A

I was shopping in the supermarket when I heard a young voice.

“Mom, come here! There’s this lady here my size!”

The mother rushed to her son; then she turned to me to apologize.

I smiled and told her, “It’s okay.” Then I talked to the boy, “Hi, Mickey, I’m Darry Kramer. How are you?”

He studied me from head to toe, and asked, “Are you a little mommy?”

“Yes, I have a son,” I answered.

“Why are you so little?” he asked.

“It’s the way I was born,” I said. “Some people are little. Some are tall. I’m just not going to grow any bigger.” After I answered his other questions, I shook the boy’s hand and left.

My life as a little person is filled with stories like that. I enjoy talking to children and explaining why I look different from their parents.

It takes only one glance to see my uniqueness. I stand three feet nine inches tall. I was born an achondroplasia dwarf (侏儒). Despite this, I did all the things other kids did when I was growing up.

I didn’t realize how short I was until I started school. Some kids picked on me, calling me names. Then I knew. I began to hate the first day of school each year. New students would always stare at me as I struggled to climb the school bus stairs.

But I learned to smile and accept the fact that I was going to be noticed my whole life. I decided to make my uniqueness an advantage rather than a disadvantage. What I lacked in height, I made up for in personality.

I’m 47 now, and the stares have not diminished as I’ve grown older. People are amazed when they see me driving. I try to keep a good attitude. When people are rude, I remind myself, “Look what else I have---a great family, nice friends.”

It’s the children’s questions that make my life special. I enjoy answering their questions. My hope is that I will encourage them to accept their peers (a person of the same age, class, position, etc.), whatever size and shape they come in, and treat them with respect.

41.Why did the mother apologize to the author?

      A.Because the boy ran into the author.

       B.Because the boy laughed at the author.

       C.Because the boy said the author was fatter than him.

       D.Because the mother thought the boy’s words had hurt the author.

42.When did the author realize that she was too short?

       A.When she grew up.

       B.When she was 47 years old.

       C.When she began to go to school.

       D.When she met the boy in the supermarket.

43.Which of the following word can best replace the underlined word “diminished”?

       A.dismissed         B.increased         C.decreased         D.discriminated

44.How does the author feel about people’s stares?

      A.Angry.            B.Calm.              C.Painful.           D.Discouraged.

The term IQ, or Intelligence Quotient, generally describes a score on a test that rates the subject’s cognitive(认知的) ability as compared to the general population. IQ tests use a standardized scale with 100 as the median score. On most tests, a score between 90 and 110 or the median plus or minus 10 indicates average intelligence. A score above 130 indicates exceptional intelligence and a score below 70 may indicate mental retardation (智力迟钝). Like their predecessors, modern tests do take into account the age of a child when determining an IQ score. Children are graded relative to the population at their developmental level.

IQ tests are designed to measure your general ability to solve problems and understand concepts. This includes reasoning ability, problem-solving ability, the ability to perceive relationships between things and the ability to store and regain information. IQ tests measure this general intellectual ability in a number of different ways. They may test: the ability to visualize control of shapes; the ability to solve problems;the ability to complete sentences or recognize words when letters have been rearranged or removed; the ability to recall things presented either visually or aurally(听觉上).

Most people perform better on one type of question than on others, but experts have determined that people who are good at in one category do similarly well in the other categories, and if someone does poorly in any one category, he/she also does poorly in the others. Based on this, these experts theorize there is one general element of intellectual ability that determines other specific cognitive abilities. The best tests, therefore, feature questions from many categories of intellectual ability so that the test isn’t weighted toward one specific skill.

IQ tests measure your ability to understand ideas, not the quantity of your knowledge; learning new information does not automatically increase your IQ. Learning may exercise your mind, however, which could help you to develop greater cognitive skills, but scientists do not fully understand this relationship. The scientists are still in the dark about the connection between learning and mental ability, as are the workings of the brain and the nature of intellectual ability. Intellectual ability does seem to depend more on genetic factors than on environmental factors, but most experts agree that environment plays some significant role in its development.

45. In determining an IQ score, _______________.

  A. the subject’s cognitive ability is compared with his/her former performance

  B. the children’s age is taken into consideration

  C. 100 is treated as the standard score

  D. children of various developmental levels are tested

46. What can we learn from the third paragraph?

  A. A person who does poorly in one category is not necessarily poor in other categories.

  B. Experts got the conclusion that learning new information can automatically increase your IQ.

  C. The general intellectual ability can determine specific cognitive abilities to some extent.

  D. Whether a person can do well in one category is not decided by IQ.

47. What is known to be certain about intellectual ability?

  A. The relationship between learning and intellectual ability.

  B. The connection between the workings of the brain and the nature of intellectual ability.

  C. Environment does play a role in the development of intellectual ability.

  D. Genetic factors are the determining factors of intellectual ability.

Life has changed in Mexico City. Streets normally filled with people are empty. One of the most popular professional soccer teams recently played a game in an empty stadium that can seat more than 100,000 people. It’s swine (猪) flu that has made life in Mexico City grind to a halt (慢慢停了下来).

Seemingly out of nowhere, swine flu has caused confirmed deaths in 12 countries as of April 30. It has sent a wave of alarm around the world. Governments are trying to find ways to prevent further outbreaks. The World Health Organization has raised its swine flu global threat level to five out of six.

People may be familiar with bird flu, but they know little about swine flu. Swine flu is a contagious (传染性的) respiratory (呼吸的) disease in pigs. It is caused by a type-A influenza virus.

Humans can also catch swine flu. The virus causes regular outbreaks in pigs, but people usually do not catch it. However, there have been cases of the virus spreading to people, and then from one person to another.

The symptoms of swine flu are similar to the common flu. They include fever, lethargy (无精打采), lack of appetite, coughing, runny nose, sore throat, nausea (恶心), and vomiting (呕吐). The high proportion of young adults among the deaths is one of several mysteries about this virus. Most of the dead had lung damage. What caused it is not yet known.

The virus spreads the same way the common flu does. When an infected person coughs or sneezes around another person, the latter is put at risk. People can get the disease by touching something with the flu virus on it and then touching their mouth, nose or eyes.

There are medicines to treat swine flu. Doctors suggest using anti-viral drugs. They keep the virus from reproducing inside the body.

Although there are no vaccines (疫苗) for it now, several everyday steps can help prevent the spread of the virus: washing hands frequently; avoiding close contact with people who are sick; and avoiding touching surfaces that might have the virus on it.

People may worry that they will get swine flu from eating or preparing pork. In fact, you cannot catch the virus from pork products if they have been properly prepared and cooked. Cooking food at temperatures of 71°C kills the virus.

52. What is the main idea of the passage?

A. It mainly tells us how swine flu broke out in Mexico City.

B. It presents the reader with some information concerning swine flu.

C. It tells us the differences between swine flu and bird flu.

D. It mainly tells readers the dangers caused by swine flu.

53. The following tips can protect us from swine flu EXCEPT ________.

A. keeping us away from other people

B. washing hands frequently

C. avoiding close contact with sick people

D. avoiding touching surfaces that might have the virus on them

54. What’s the main idea of the first paragraph?

A. Mexico City is really a place of horror now.

B. People in Mexico City like staying at home.

C. People in Mexico City don’t like soccer.

D. Swine flu has seriously affected people’s life in Mexico City.

55. What can we infer from the passage?

A. At present there still aren’t effective vaccines for swine flu.

B. Swine flu virus cannot spread in the air.

C. From now on, people can’t eat pork if they want to be safe.

D. All of the dead killed by swine flu had lung damage.

Cole Bettles had been rejected by a number of universities when he received an e-mail from the University of California, San Diego, last month, congratulating him on his admission and inviting him to tour the campus. His mother booked a hotel in San Diego, and the 18-year-old Ojai, California, high school senior arranged for his grandfather, uncle and other family members to meet them at the campus for lunch during the Saturday tour.

“They were like ‘Oh my God, that’s so awesome (棒的)’,” Bettles said. Right before he got in bed, he checked his e-mail one last time and found another message saying the school had made a mistake and his application had been denied.

In fact, all 28,000 students turned away from UC San Diego, in one of the toughest college entrance seasons on record, had received the same incorrect message. The students’ hopes had been raised and then dashed (破灭) in a cruel twist that shows the danger of instant communications in the Internet age.

UCSD admissions director Mae Brown called it an “administrative error” but refused to say who had made the mistake, or if those responsible would be disciplined (受训).

The e-mail, which began, “We’re thrilled that you’ve been admitted to UC San Diego, and we’re showcasing (展示) our beautiful campus on Admit Day,” was sent to the full 46,000 students who had applied, instead of just the 18,000 who got in, Brown said.

The error was discovered almost immediately by her staff, who sent an apology within hours.

“It was really thrilling for a few hours; now he’s crushed (压垮),” said Cole’s mother, Tracy Bettles. “It’s really tough on them.

The admissions director said she was in the office on Monday until midnight answering e-mails and phone calls from disappointed students and their parents. She said she took full responsibility for the error. “We accessed the wrong database. We recognize the incredible pain receiving this false encouragement caused. It was not our intent (意图).”

56. A total of_____ received an admission e-mail from the University of California, San Diego (UCSD).

A. 18,000 candidates     B. 28,000 students   C. 46,000 applicants     D. 18 students

57. From the text, we can see that ________.

A. Cole Bettles had been rejected by several universities but was finally accepted by a good one

B. Cole Bettles felt on top of the world one moment but the next he was flooded with bitter disappointment by the final message

C. Cole Bettles could hardly believe the fact that he was rejected by UCSD, one of the best universities

D. Cole Bettles was disappointed that he couldn’t go to tour the beautiful campus of UCSD with his family

58. Which of the following statements is TRUE about the wrong e-mail message?

A. The mistake was made on purpose to cause pain among the applicants.

B. It was UCSD admissions director Mae Brown who made the mistake.

C. UCSD admissions staff got information from the wrong database.

D. Staff did not discover the mistake until next Monday.

59. The admissions director Mae Brown did what she could to __________.

A. make up for the mistake

B. punish herself for the mistake

C. protect the person who made the mistake

D. help the disappointed students enter the university

60. What’s the correct understanding of the sentence “it’s really tough on them” in Paragraph 7?

A. Being rejected time and again is even hard for adults, let alone them.

B. The university staff has made a great effort to correct the mistake.

C. It’s difficult for senior students to be admitted by the universities.

D. The unexpected twist from thrill to pain is just too much for these high school seniors.

One possible version A

Nowadays it’s common for parents to drive their children to and from school. Recently a survey has been done on the issue. Half of the people surveyed are in favor of the practice. Among them, half believe that driving children to school saves time. Another 30% think it comfortable to go by car, especially in harsh weather. About 15% consider it a good choice just for the sake of children’s safety. Still others think it offers more chances for parents to communicate with their children.

Personally, I like the idea of driving children to and from school. The children may have more sleep time by getting up a bit later. Also, more and more families own private cars. The parents tend to drive to work. It would save a lot of trouble for children if they give their children a ride on their way to and from work.   (121)

One possible version B

Nowadays it’s common for parents to drive their children to and from school. Recently a survey has been done on the issue. Half of the people surveyed are against the practice. About 55% of them believe it results in heavier traffic, especially in rush hours. Around 30% think that driving kids to and from school will add to pressure on parents. It takes time, expense and effort to do this. Still again, 15% worry that children may become more dependent on their parents in the long term.

While I agree that going to school by car is a better solution for young children, I don’t think it a good idea for older children. With high pressure on their studies, they need to find extra time for exercise. It would be better if they chose to cycle or walk to and from school instead of taking a car, which will definitely help them keep fit.  (128)
