21（1）如圖7所示，是多用電表示意圖。某同學想用此多用電表檢測一下家庭電路的電壓，他應該將多用電表的擋位選擇旋鈕放在位置。圖7乙中示數即為他的測量值，則他所測家庭電路的電壓為 V。

（2）用如圖8所示的實驗裝置驗證機械能守恒定律。實驗所用的電源為學生電源，能輸出電壓為6V的交流電和直流電。重錘從高處由靜止開始落下，重錘上拖著的紙帶通過打點計時器打出一系列的點，對紙帶上的點的痕跡進行測量，即可驗證機械能守恒定律。

①下列列舉了該實驗的幾個操作步驟：

A．按照圖示的裝置安裝器件；

B．將打點計時器接到電源的6V直流輸出端上；

C．用天平測量出重錘的質量；

D．釋放懸掛紙帶的夾子，同時接通電源開關打出一條紙帶；

E．測量打出的紙帶上某些點之間的距離；

F．根據測量的結果計算重錘下落過程中減少的重力勢能是否等于增加的動能。

指出其中沒有必要進行的或者操作不恰當的步驟，將其選項對應的字母填在下面的空行內，并說明其原因。

答：

。

②如圖9所示。根據打出的紙帶，選取紙帶上打出的的連續五個點A、B、C、D、E，測出A點距起始點O的距離為s₀，點A、C間的距離為s₁ ，點C、E間的距離為s₂，使用交流電的頻率為f，則根據這些條件可以計算出打C點時重錘的速度v_c= 。還可以計算出重錘下落的加速度a= 。

③根據紙帶算出的相關各點的速度v，量出下落的距離h，則以v²為縱軸，以h為橫軸，根據實驗數據繪出的v²-h圖線應是圖10中的。

④在驗證機械能守恒定律的實驗中發現，重錘減小的重力勢能總是大于重錘動能的增加，其原因主要是因為在重錘下落過程存在著阻力的作用，可以通過該實驗裝置測定該阻力的大小。若已知當地重力加速度為g，還需要測量的物理量是。則重錘在下落過程中受到的平均阻力大小F= 。

22．如圖11所示，水平絕緣粗糙的軌道AB與處于豎直平面內的半圓形絕緣光滑軌道BC平滑連接，半圓形軌道的半徑R=0.40m。在軌道所在空間存在水平向右的勻強電場，電場線與軌道所在的平面平行，電場強度E=1.0×10⁴ N/C。現有一電荷量q=+1.0×10^-4C，質量m=0.10kg的帶電體（可視為質點），在水平軌道上的P點釋放由靜止釋放，帶電體恰好能通過半圓形軌道的最高點C，然后落至水平軌道上的D點。取g=10m/s²。求：

（2）帶電體運動到圓形軌道B點時對圓形軌道的壓力大小；

（3）帶電體在從A開始運動到落至D點的過程中的最大動能。

23.光子具有能量，也具有動量。光照射到物體表面時，會對物體產生壓強，這就是“光壓”。光壓的產生機理如同氣體壓強：大量氣體分子與器壁的頻繁碰撞產生了持續均勻的壓力，器壁在單位面積上受到的壓力就是氣體的壓強。設太陽光每個光子的平均能量為E，太陽光垂直照射地球表面時，在單位面積上的輻射功率為P₀。已知光速為c，則光子的動量為E/c。求：

（1）若太陽光垂直照射在地球表面，試計算時間t內照射到地球表面上半徑為r的圓形區域內光子的總動量。

（2）一般情況下，太陽光照射到物體表面時，一部分會被反射，還有一部分被吸收。當物體表面的反射系數為ρ時，則在每秒內照射到物體表面的全部n個光子中，有(1-ρ)n個被吸收而ρn個被反射。若太陽光垂直照射在地球表面反射系數為ρ、半徑為r的某圓形區域內，則在時間t內照射到此區域的光子的總動量的變化量是多少？

（3）在第（2）問中太陽光在圓形區域表面產生的光壓（用I表示光壓）是多少？

24．圖12虛線框內為某種電磁緩沖車的結構示意圖，在緩沖車的底板上沿車的軸線固定有兩個足夠長的平行絕緣光滑導軌PQ、MN，在緩沖車的底部還安裝有電磁鐵（圖中未畫出），能產生垂直于導軌平面的勻強磁場，磁場的磁感應強度為B。在緩沖車的PQ、MN導軌內有一個由高強度材料制成的緩沖滑塊K，滑塊K可以在導軌上無摩擦地滑動，在滑塊K上繞有閉合矩形線圈abcd，線圈的總電阻為R，匝數為n，ab的邊長為L。緩沖車的質量為m₁（不含滑塊K的質量），滑塊K的質量為m₂。為保證安全，要求緩沖車廂能夠承受的最大水平力（磁場力）為F_m，設緩沖車在光滑的水平面上運動。

（1）如果緩沖車以速度v₀與障礙物碰撞后滑塊K立即停下，則滑塊K線圈中ab邊受到磁場力的大小是多少；

（2）如果緩沖車與障礙物碰撞后，滑塊K立即停下，為保證安全，緩沖車行駛的速度應滿足什么條件；

（3）如果緩沖車以速度v勻速行駛時，在它前進的方向上有一個質量為m₃的靜止物體C，滑塊K與物體C相撞后粘在一起，碰撞時間極短。求滑塊K與物體C碰撞結束時緩沖車受到的水平磁場力的大小；

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：閱讀理解（第一節20小題，第二節5小題，每題2分，滿分50分）

第一節：閱讀下列短文，從每題所給的四個選項（A、B、C和D）中，選出最佳選項,并在答題卡上將該項涂黑。

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.

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.

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(認知的) 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 (智力遲鈍). 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（聽覺上）.

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 (豬) flu that has made life in Mexico City grind to a halt (慢慢停了下來).

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 (傳染性的) 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 (無精打采), lack of appetite, coughing, runny nose, sore throat, nausea (惡心), and vomiting (嘔吐). 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.

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 (破滅) 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 (受訓).

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 (壓垮),” 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 (意圖).”

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)
