在能源消耗日益增长,人们的环保意识不断提高的今天,如何利用现有的能源以及开发新能源已成为当务之急.我国建造三峡水电站,很重要的方面就是将现有的水能转变为电能;同时人们以水为原料,积极开发氢能源.

(1)下表是长江三峡工程的部分设计数据(为了便于计算,个别数据做了近似处理).若26台发电机组全部建成,按设计要求年发电时间为______天.

大坝坝高/m185
长/m2335
最大蓄水位/m175
水库总库容量/m33.930×1010
防洪库容量/m32.215×1010
平均年流量/m34.510×1010
电站总装机数/台26
总装机工作时的发电机总功率/Kw1.800×107
年平均发电量/Kw﹒h8.640×1010
(2)自2003年6月1日开始,三峡蓄水工程正式启动,中央电视台以“见证三峡135”为题进行了全面报道.三峡的年发电量相当于每年燃烧3000万吨原煤产生的电能.三峡工程的全面启动将有助于控制①温室效应②白色污染③SO2排放④烟尘

A、①②④B、①②③C、①③④D、②③④

(3)已知氢气的燃烧值为1.43×108J/kg,比煤和石油高出许多,且燃烧后的产物是水蒸气,排到大气中不会造成污染,氢在地球上含量很多,主要以化合物存在于水中.如何把氢廉价地提取出来,是科学家正在研究的新课题,有资料表明:在20kv、500A的条件下,通电24h可电解9t水.请你从能源的角度,通过计算分析这种方法获得氢能源是否有价值,并提出一种更好的氢能源开发设想.

Self-employed private physicians who charge a fee for each patient visit are the foundation of medical practice in the United States. Most physicians have a contract relationship with one or more hospitals in the community. They send their patients to this hospital, which usually charges patients according to the number of days they stay and the facilities(operating room, tests, medicines that they use). Some hospitals belong to a city, a state or, in the case of veteran's hospitals, a federal government agency. Others are operated by religious orders(教会) or other non-profit groups.

Some medical doctors are on salary. Salaried physicians may work as hospital staff members, or residents, who are often still in training. They may teach in medical schools, be hired by corporations to care for their workers or work for the federal government's Public Health Service.

Physicians are among the best paid professionals in the United States. In the 1980s, it was not uncommon for medical doctors to earn incomes of more than $ 100 000 a year. Specialists, particularly surgeons, might earn several times that amount. Physicians list many reasons why they deserve to be so well rewarded for their work. One reason is the long and expensive preparation required to become a physician in the United States. Most would be physicians first attend college for four years, which can cost nearly $ 20 000 a year at one of the best private institutions. Prospective physicians then attend medical school for four years. Tuition alone can exceed $ 10 000 a year. By the time they have obtained their medical degrees, many young physicians are deeply in debt. They still face three to five years of residency(实习阶段) in a hospital, the first year as an apprentice physician. The hours are long and the pay is relatively low.

Setting up a medical practice is expensive, too. Sometimes several physicians will decide to establish a group practice, so they can share the expense of maintaining an office and buying equipment. These physicians also take care of each other's patients in emergencies.

Physicians work long hours and must accept a great deal of responsibility. Many medical procedures, even quite routine ones, involve risk. It is understandable that physicians want to be well rewarded for making decisions which can mean the difference between life and death.

1. According to the passage, it is very unlikely that an American hospital is owned by _______.

A. a church     B. a corporation     C. a city         D. a state

2. The expenses for becoming a doctor are spent on _______.

A. schooling and retraining          B. practice in a hospital

C. facilities he or she uses            D. education he or she receives

3. According to the passage, how long does it take for a would-be physician to become an independent physician in the USA?

A. About seven years.                  B. Eight years.

C. Ten years.                               D. About twelve years.

4. Sometimes several physicians set up a group medical practice mainly because _______.

A. there are so many patients that it is difficult for one physician to take care all of them

B. they can take turns to work long hours

C. facilities may be too much of a burden for one physician to shoulder

D. no one wants to assume too much responsibility

5. Which of the following statements could fully express the author's view towards physicians’ payment in the USA?

A. For their expensive education and their responsibility, they deserve a handsome pay.

B. It is reasonable for physicians to have a large income because their work is very dangerous.

C. Physicians should be better paid because they work long hours under bad conditions.

D. Physicians have great responsibility, so it is understandable that they should be well rewarded.
