Robots

1. Most sophisticated (先進的) Japanese robots, which have vision systems and work at veryhigh speeds, are still based on American designs. Studies of robots, particularly computercontrol software, are considered to be generally less advanced in Japan than in America orEurope.

2. Although industrial robots were originally developed as devices for simply handling objects,today their commonest uses are for more skilled work like welding (焊接), spray-paintingand assembling components.

3. In Britain robot sales appropriately peaked in 1984, but have been declining ever since. Thisis partly because British wage rates are too low to make robots financially attractive and partlybecause engineers now have more experience with robots and are more aware of thedifficulties of introducing them effectively.

4. It has been calculated that a robot uses on average about 100 times more energy than a humanto do an equivalent job.

5. It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormousnumber because comics are so popular that they make up a third of all material published inJapan.

6. The reliability of robots is measured in their M. T. B. F. or mean time between failures. Thishas risen from about 250 hours in the mid-1970s to about 10, 000 hours today (equivalent to

working 18 hours a day for two years ). One way robot manufactures have increasedreliability is to test every single component they buy, instead of the normal procedure of justtesting a small sample.

7. The biggest single benefit of introducing robots claimed by Japanese companies is that theyincrease quality control. Once programmed, the robots can work more accurately andconsistently than humans, who can get tired and bored.

Human Space Exploration

While scientists are searching the cause of the Columbia disaster, NASA is moving aheadwith plans to develop a new craft that would replace shuttles (航天飛機) on space station missions by 2012 and respond quickly to space station emergencies.

The space agency released the first set of mission needs and requirements several days agofor orbital space plane ( 軌道航天飛機), which would be designed to transport a crew of fourto and from the International Space Station.

Although it includes few specifics, the plan states the orbiter (軌道航天飛機) will besafer, cheaper and require less preparation time than the shuttle. It would be able to transportfour crew members by 2012 —— though it would be available for rescue missions by 2010. NASAsays the craft should be able to transport injured or ill space station crew members to "definitive(決定性的) medical care" within 24 hours.

The release of the requirements showed NASA remains focused on the long-term prioritiesof space exploration, even as questions exist concerning the loss of Columbia and its sevenmember crew on February 1, 2003.

Expels at Marshall Space Flight Center in Huntsville, Alabama, have been working foryears on a successor to the shuttle. The project, known as the Space Launch Initiative (倡議),was divided last year into two parts -- one focusing on a future launch vehicle, the other on aspace station orbiter. The orbiter is expected to be ready sooner.

The program's managers say NASA officials have told them not to alter Space Launch Initiative in light of the Columbia disaster.

U.S. President George W. Bush asked Congress for about US $1 billion for Space LaunchInitiative in 2004, funds that would be almost equally split between the Orbital Space Plane andNext Generation Launch Technology.

NASA plans to design the new space craft to_______.

A．control the International Space Station

B．carry astronauts to the International Space Station

C．transport equipment to the International Space Station

D．train astronauts in space flights

32、 Besides its main mission, the orbiter would also be used as_______.

A．a(chǎn) medical research center

B．a(chǎn) space station

C．a(chǎn) space ambulance

D．a(chǎn) passenger plane

33、 The design of the orbiter indicates _______.

A．NASA's determination to continue space exploration

B．NASA's disadvantage in space technology

C．the great pressure from Congress on NASA

D．a(chǎn) heavy defeat for NASA

34、 When did NASA start working on a successor to the shuttle?

A．One year before the Columbia disaster

B．One year after the Columbia disaster.

C．Immediately after the Columbia disaster.

D．Years before the Columbia disaster.
