第Ⅱ卷(非选择题  共11题    共180分)

21.(18分)

    某同学想测量一段电阻丝的电阻率,其中使用了自己利用电流表改装的电压表。整个实验过程如下:

           

               图1                      图2                     图3

A.测量电流表的内阻。按图1连接电路,将电位器R调到接入电路的阻值最大。闭合开关S1,调整R的阻值,使电流表指针偏转到满刻度;然后保持R的阻值不变,合上开关S2,调整电阻箱R′的阻值,使电流表指针达到半偏,记下此时R′的阻值;

B.计算出改装电压表应串联的电阻R0的值。将电阻R0与电流表串联,则R0与电流表共同构成一个新的电压表;

C.将改装的电压表与标准电压表接入如图2所示的校准电路,对改装的电压表进行校准;

D.利用校准后的电压表和另一块电流表,采用伏安法测量电阻丝的电阻;

E.测量电阻丝的直径和接入电路的电阻丝的长度;

F.计算出电阻丝的电阻率。

根据上述实验过程完成下列问题:

(1)用螺旋测微器测量金属丝的直径,选不同的位置测量3次,求出其平均值d。其中一次测量结果如图3所示,图中读数为_____________mm;

(2)根据图1电路,请在图4中画出连线,将器材连接成测量电流表内阻的实验电路;

图4

(3)已知电流表的满偏电流为200μA,若当电流表指针偏转到正好是满偏刻度的一半时R′的阻值为500Ω。要求改装后的电压表的量程为2 V,则必须给电流表串联一个阻值为R0=____________Ω的电阻;

(4)在对改装后的电压表进行校准时,发现改装后的电压表的测量值总比标准电压表的测量值小一些,造成这个现象的原因是(    )

A.电流表内阻的测量值偏小,造成串联电阻Ro的阻值偏小

B.电流表内阻的测量值偏大,造成串联电阻Ro的阻值偏小

C.电流表内阻的测量值偏小,造成串联电阻Ro的阻值偏大

D.电流表内阻的测量值偏大,造成串联电阻Ro的阻值偏大

(5)在利用校准后的电压表采用伏安法测量电阻丝的电阻时,由于电压表的表盘刻度仍然是改装前电流表的刻度,因此在读数时只能读出电流表指示的电流值a。测量电阻丝的电阻时,可以读得一系列a和对应流经电阻丝的电流b。该同学根据这一系列a、b数据做出的a-b图线如图5所示,根据图线可知电阻丝的电阻值为_____________Ω。

(2)当ab杆保持静止时,求螺线管内磁场的磁感应强度B的变化率;

(3)若螺线管内方向向左的磁场的磁感应强度的变化率(k>0)。将金属杆ab由静止释放,杆将向下运动。当杆的速度为v时,仍在向下做加速运动。求此时杆的加速度的大小。设导轨足够长。

(2)图3为潮汐发电的示意图。左侧是大海,中间有水坝,水坝下装有发电机,右侧是水库。当涨潮到海平面最高时开闸,水由通道进入海湾水库,发电机在水流的推动下发电,待库内水面升至最高点时关闭闸门;当落潮到海平面最低时,开闸放水发电。设某潮汐发电站发电有效库容V=3.6×106 m3,平均潮差Δh=4.8 m,一天涨落潮两次,发电四次。水流发电的效率η1=10%。求该电站一天内利用潮汐发电的平均功率P;

(3)传送机正常运行时,1秒钟有m=50 kg的煤从漏斗中落到传送带上。带动传送带的电动机将输入电能转化为机械能的效率2=80%,电动机输出机械能的20%用来克服传送带各部件间的摩擦(不包括传送带与煤之间的摩擦)以维持传送带的正常运行。若用潮汐发电站发出的电给传送机供电,能同时使多少台这样的传送机正常运行?

While watching the Olympics the other night, I came across an unbelievable sight. It was not a gold medal, or a world record broken, but a show of courage.

The event was swimming and started with only three men on the blocks. For one reason or another, two of them false started, so they were disqualified. That left only one to compete. It would have been difficult enough, not having anyone to race against, even though the time on the clock is important.

I watched the man dive off the block and knew right away that something was wrong. I’m not an expert swimmer, but I can tell a good dive from a poor one, and this was not exactly medal quality. When he resurfaced, it was evident that the man was not out for gold―his arms were waving in an attempt at freestyle. The crowd started to laugh. Clearly this man was not a medal competitor.

I listened to the crowd begin to laugh at this poor man who was clearly having a hard time. Finally he made his turn to start back. It was pitiful. He made a few desperate strokes and you could tell he was worn out.

But in those few awful strokes, the crowd had changed.

No longer were they laughing, but beginning to cheer. Some even began to stand and shout “Come on, you can do it!” and he did.

A clear minute past the average swimmer, this young man finally finished his race. The crowd went wild. You would have thought that he had won the gold, and he should have. Even though he recorded one of the slowest times in Olympic history, this man gave more heart than any of the other competitors.

Just a short year ago, he had never even swum, let alone race. His country had been invited to Sydney.

In a competition where athletes remove their silver medals feeling they have somehow been cheated out of gold, or when they act so proudly in front of their competitors, it is nice to watch an underdog.

59. From the passage we can learn that the young man______.

A. made his turn to start back pitifully

B. was skillful in freestyle in the game

C. swam faster than the average swimmer

D. was not capable enough to win the medal

60. The crowd changed their attitudes because______.

A. they felt sorry for the young man

B. they were moved by the young man

C. they wanted to show their sympathy

D. they meant to please the young man

61. According to the passage, “it is nice to watch an underdog” probably means______.

A. it’s amusing to watch a man with awful swimming skills

B. it’s amazing to watch an ordinary man challenging himself

C. it’s cheerful for athletes to act proudly before their competitors

D. it’s brave enough for some athletes to remove the silver medals

62. What’s the best title for the passage? ______?

A. Compete for Gold!           B. Try again!

C. Break a Record!             D. Go for it!

C

In Alexandria, Virginia, the two thousand students at T.C. Williams High School started classes last month in a new building. It was built as a “green” school based on requirements from the United States Green Building Council.

The council is a nonprofit organization made up of building industry leaders. It has a rating system for buildings called Leadership in Energy and Environmental Design, or LEED.

In 2001, there were four schools asking for LEED certification. Now there are four hundred, including T.C.  Williams. So far,  fifty-eight schools have been recognized for meeting the requirements. These include protecting natural areas and limiting the amount of chemicals in building materials. They also include better lighting and improved indoor air quality. Buildings are also rated on how well they use energy and water, and on things like the use of recycling programs. At T. C. Williams, one example of green design can be seen in the many windows that let in natural light. Students say the sunny rooms help them stay awake during class.

A rooftop garden is designed to provide storm water control and help keep the building cool in the sun. And an underground tank can store 1,700,000 liters of rainwater for air conditioning and other systems.

The new building cost about 90,000,000 dollars to build. It stands next to the old T. C. Williams building, which officials say will slowly be taken apart and recycled. T.C. Williams High School is still waiting for the final part of the LEED certification process. Schools receive points for the number of requirements they meet. Buildings are rated silver, gold or platinum.

Around the country, concerns about limited budgets for public schools sometimes lead to objections to investing in “green” schools. But the Green Building Council points to a report by Capital E, a Washington D. C. company that serves the clean energy industry. Capital E examined the cost of thirty “green” schools in the United States. It says the average cost was only two percent higher compared to a traditional school.And it says this extra cost is small compared to the savings over time from lower energy and water costs and healthier students.

63. The United States Green Building Council aims to ______.

A. collect money for “green” schools

B. construct “green” buildings on its own

C. promote the construction of “green” schools

D. evaluate the “greenness” of any school building

64. We know from the passage that ______.

A. LEED evaluates the buildings at four different levels

B. Capital E designed many requirements for “green” schools

C. T. C. Williams High School has received LEED certification

D. LEED is provided by the United States Green Building Council

65. The underlined word they in Paragraph 3 refers to ______.

A. the requirements

B. the natural areas

C. the building materials

D. the amount of chemicals

66. What can be inferred from the last paragraph? ______.

A. Green schools cost more than traditional ones.

B. Capital E is devoted to the clean green industry.

C. Green schools will have more benefits in the long term.

D. Limited budgets cause a disagreement on “green” schools.

While most teenagers earn the minimum wage from weekend jobs, Jonathan Grubin, a 16-year-old boy, has logged on to an online success which turned over £ 75,000 last year.

Now his success is already beginning to show with the launch of ForFree4U. co. uk, which offers visitors free iPods and digital cameras for signing up their friends to its advertisers. Jonathan has got more than 55,000 members to the site in less than two years, sending off £ 25,000 worth of products.

His success is down to a business move known as affiliate marketing, a web-based marketing practice in which a business rewards one or more affiliates for each visitor or customer brought about by the affiliate’s marketing efforts.

The Royal Grammar School student said: “I have always been interested in websites and the ideas behind them. I thought, ‘if only there was another way I could get my hands on these goods’, so I made a website for a bit of fun.” Jonathan added: “I partner with some advertisers, and they send me commission(佣金) each time I get them a new customer. I offer visitors to my website a reward when they sign up.”

“Advertisers were very quick to realise the potential of the network.  Affiliate marketing is highly successful for advertisers because they only pay when they see results.”

“When you run an expensive television advertising campaign, nothing is guaranteed. But with my business model, advertisers only pay their commission when they see results.”

Jonathan, who works from his computer at home, launched his first website when he was 12 offering mobile phone wallpapers and screensavers after rival sites were charging youngsters for downloads.

He also runs livenewcastle. co. uk, a resource website for Newcastle with listings, reviews and directories. He added: “I remember receiving my first cheque, it was £ 10.44, and I was amazed that I had received it. The only thing I really want to do is to be able to work for myself.”

“There are a lot of downsides, but there are advantages too. The fact is that I am so young, and when I’m 20, I’m going to have a lot of knowledge and experience that most people won’t have until they are 30 or 40.”

67. Which of the following helps lead to the success of ForFree4U. co. uk? ______?

A. It provides visitors with presents for signing up their friends to its advertisers.

B. It offers teenagers mobile phone wallpapers and screensavers for free.

C. It gets payment when it publishes ads.

D. It charges youngsters for downloads.

68. Which of the following is NOT true according to the passage?

A. Jonathan set up his first website when he was twelve.

B. Jonathan is a student of Royal Grammar School.

C. Jonathan founded the websites for money only.

D. Jonathan is in charge of two websites now.

69. According to the passage, it’s obvious that ______.

A. Jonathan’s websites are popular with both visitors and advertisers

B. visitors sign up on Jonathan’s website in order to get rewards

C. advertisers pay for their products being advertised online

D. Jonathan is interested in working all by himself

70. The passage is mainly about ______.

A. a smart online advertising technique

B. a promising business web-master

C. a web-based marketing producer

D. a successful online marketing

Today’s career assumptions are that you can get a lot of development, challenge and job satisfaction and not necessarily be in a management role.

“I hated all the meetings,” says a 10-year award-winning manager, “And I found the more you did for people who worked for you, the more they expected.”

Managing others is always a tough task, but in the past that stress was balanced by hopes for career mobility and financial rewards. Along with a sizable pay raise, people chosen as managers Would begin a nearly automatic climb up the career ladder to lucrative executive private benefits: company cars, club memberships, plus the key to the executive washroom.

But in today’s global, more competitive showground, a manager sits in an insecure chair. Restructuring has removed layer after layer of management as companies come to view their organizations as collections of talents rather than hierarchies(等级). There are far fewer steps for  managers to climb. Also, managerial jobs demand more hours and headaches than ever before but offer slim, if any, financial paybacks and perks.

Now managers must manage many people who are spread over different locations, even over different continents. They must manage across functions with, say, design, finance and marketing.

In an age of entrepreneurship, when the most praised people in business are those launching something new, management seems like an invisible, thankless role. Employers are looking for people who can do things, not for people who make other people do things.

In addition, the Dilbert factor is at work. With Dilbert’s popular cartoon character as well as many television situation comedies routinely describing managers as fools or enemies, they just don’t get much respect any more.

Moreover, it may not pay to be a manager at least not the way it once did. Ms. Chmielewski says, “The emotional rewards can be great, and there were times when I enjoyed management. But a 10-to-11-hour day and one weekend day a month is the norm.”

With more people cautious of joining management, are companies being hurt or worrying about developing future leaders? Not many are. While employers have fired a lot of managers, they believe many more candidates linger on at many companies. “Another reason why companies aren’t short of managers”, argues Robert Kelley, a business professor, “is that so many workers today are self-managed, either individually or via teams, you don’t need a manager.”

71. By writing the passage, the writer seems to ______.

A. explain reasons for firing managers

B. advise people not to become managers

C. express dissatisfaction of some managers

D. encourage managers to be more competitive

72. Compared with the past, the managing job today is more ______.

A. demanding    B. rewarding    C. questionable    D. acceptable

73. The author mentions what Ms. Chmielewski says to reflect that ______.

A. the managers’low working efficiency makes them less paid

B. the gain of being a manager is not as satisfactory as before

C. she enjoys great emotional rewards of being a manager

D. she misses the past enjoyment of being a manager

74. What can we learn from the passage? ______?

A. Managers have more chances to be promoted now.

B. Managers were not satisfied with the way they were treated.

C. It is unnecessary for a qualified manager to manage a variety of fields.

D. The cartoon character by Dilbert contributes to the bad image of managers.

75. What can we infer from the last paragraph? ______?

A. More and more people are eager to become managers.

B. There will be more managers to be employed in the future.

C. Employers think it easy for them to find managers in the future.

D. Team-work makes it possible for companies not to hire more managers.
