科目：高中英語 來源：湖南省衡陽市八中2011－2012學年高二上學期第二次月考英語試題 題型：050

Read the following four passages．Each passage is followed by several questions or unfinished statements．For each of them there are 4 choices marked A, B, C and D．Choose the one that fits best according to the information given in the passage．

　　Batteries can power anything from small sensors to large systems．While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves．University of Missouri(MU)researchers are developing a nuclear energy source that is smaller, lighter and more efficient．

　　“To provide enough power, we need certain methods with energy density(密度),” said Jae kwon, assistant professor of electrical and computer engineering at MU．“The radioisotope(放射性同位素)battery can provide power density that is much higher than chemical batteries．”

　　Kwon and his research team have been working on building a small nuclear battery, recently the size and thickness of a penny, intended to power various micro/nano－electromechanical systems(M/NEWS)．Although nuclear batteries can cause concerns, Kwon said they are safe．

　　“People hear the word ‘nuclear’ and think of something very dangerous,” he said．“However, nuclear power sources have already been safely powering a variety of devices, such as pace－makers, space satellites and underwater systems．”

　　His new idea is not only in the battery's size, but also in its semiconductor(半導體)．Kwon's battery uses a liquid semiconductor rather than a solid semiconductor．

　　“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶格結構)of the solid semiconductor,” Kwon said．“By using a liquid semiconductor, we believe we can minimize that problem．”

　　Together with J．David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery．In the future, they hope to increase the battery's power, shrink its size and try with various other materials．Kwon said that the battery could be thinner than the thickness of human hair．

(1)

Which of the following is true of Jae Kwon?

[　　]

A．

He teaches chemistry at MU．

B．

He developed a chemical battery．

C．

He is working on a nuclear energy source．

D．

He made a breakthrough in computer engineering．

(2)

Jae Kwon gave examples in Paragraph 4 ________．

[　　]

A．

to show chemical batteries are widely applied

B．

to indicate nuclear batteries can be safely used

C．

to describe a nuclear－powered system

D．

to introduce various energy sources．

(3)

According to Jae Kwon, his nuclear battery ________．

[　　]

A．

uses a solid semiconductor

B．

will soon replace the present ones

C．

could be extremely thin

D．

has passed the final test

(4)

The text is most probably a ________．

[　　]

A．

science news report

B．

book review

C．

newspaper ad

D．

science fiction story

PART THREE: READING COMPREHENSION (30分)
Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.
A
The Wuhan to Guangzhou MU(動車組) Train route will start to operate on the 26th of this month. The train is the fastest in the world. All the construction and preparations for the route's operation are in the final stages. Our reporter Li Dong has the details.
In a trial operation, the speed of the MU Train reached 394 kilometers per hour, the highest in the world. Though the speed during normal operation may be at 350 kilometers per hour, but this newly built high speed railway may still reduce the travel time of Wuhan to Guangzhou from more than 10 to 3 hours.
The total length of Wuhan—Guangzhou high speed railway is more than 1068 kilometers. The railway connects Hubei, Hunan and Guangdong. The total investment is more than 116 billion yuan.
Protection facilities like bars and surveillance cameras are installed along the whole railway. Zhang Shuguang, director of transport bureau of the Ministry of Railway says the safety system of the train and the route is also state of the art.
"The break distance of the train is 5 kilometers. But the MU Train can respond to any emergency situations within 32 kilometers. It's very safe."
The shortened travel distance is good news for many people. However some passengers also hope the service can be upgraded.
"The dinning and entertainment service can be better. I hope I can watch TV on the train."
"The weariness during travel can be eased if I can use internet on the train. I can feel more comfortable."
Jing Libin is the MU Train driver of the Wuhan—Guangzhou high speed railway. As a MU Train engineer who witnessed China's high speed railway development. Jing Libin says: It's a way faster!
"The development of China's railway is so fast. In the beginning of the year, the speed is only 160 kilometers per hour. Soon, the speed reached 250 kilometers. And now, it's 350 kilometers! As a driver, I am very impressed."
China plans to increase the railway operation length from the current 80 thousand kilometers to 110 thousand kilometers, which includes 18 thousand kilometers of high speed passenger railways by 2012.
Within 3 years, China plans to build an "8 Hour, High Speed Transportation Circle", which means, passengers may reach nearly all the provincial capital cities in China in about 8 hours by high speed railway. With the development of the railway, China’s economy will also continue her highest development. In the near future, China will be really powerful in the world.
56. What is the best title of the passage?
A. Fastest Train in the World
C. High Speed Railway Construction
B. Trial Operation of the MU Train
D. Newly Typed Train in the World.
57. Surveillance cameras are used for________.

58. How much time would be needed from Wuhan to Guangzhou if the train travelled at its top speed?
A. a little more than three hours           C. more than four hours
