Sometimes life gets a little dull. What used to be fun and different becomes boring. That is the time to look for something new. It is the time for a big idea to get your mind off everyday life. So why not search for extraterrestrial (地球外的) intelligence? Or even better, why not get your computer to do it for you?
Over two million people have joined the Search for Extraterrestrial Intelligence（SETI）project. Based in California, the SETI project analyzes information taken from a giant radio telescope based in South America. Its task is to look for signals from outer space that might prove that life exists on other planets.
Processing this information is far too big a job for one computer. So the SETI project workers divide the work among volunteers who visit their website. Each computer gets some information to work out from the SETI network through the Internet. This process is often known as “meta-computing”.
It is a wonderful thought. You are sleeping, eating a meal or going out with friends. All this time, your computer is searching the stars for signs that might show something is out there trying to get in touch. Volunteers are proud of being involved in the SETI project. It shows that they understand the potential (潜能) of computing. They know that it is more than just a way of working or playing games.
Meta-computing may also be creating intelligence as well as looking for it. This idea is based on the theory that human intelligence is created by the way in which different parts of the brain communicate with each other. As the saying goes, “The whole is more than the sum of its parts.” People who join the SETI project sometimes wonder whether their computer will become part of a huge network that has learned to think for itself.
1.According to the writer, meta-computing may be creating intelligence .
|
A．because human beings are intelligent |
B．because a computer works as the brain does |

C．because of a network of many computers |
D．because of the number of computers |
2. Which of the following shows the order in which the SETI network works?
|
A．Radio telescope→SETI website→Volunteers’ computer→SETI base |
|
B．Radio telescope→SETI base→SETI website→Volunteers’ computer |
|
C．SETI base→SETI website→Volunteers’ computers→Radio telescope |
|
D．SETI base→Radio telescope→SETI website→Volunteers’ computers |
3. The underlined word “it” in the last paragraph refers to _____ .
|
A．extra-terrestrial intelligence |
B．human intelligence |
|
C．the SETI project |

Health officials issued a waring over common energy-saving l一ghtbulbs(灯泡) after research showed some types could potentially harm the skin and may even raise the risk of cancer.
A study by the Health Protection Agency (HPA) found that some eco-friendly lightbuulbs release levels of ultraviolet (UV) (紫外线) radiation that are above recognized safety limits. The agency urged people who work with lamps nearby to avoid spending more than one hour within a foot of the eco-friendly bulbs. The warning was directed at those using desk lamps for long periods, such as jewellery makers, and others who might have lights close to their faces, such as car mechanics.
John O’Hagan, a scientist at the HPA’s centre for radiation, chemical and environmental dangers, began tests on the ligthbulbs after patient groups raised concern about them. Among the groups were patients with a skin disease called lupus, which makes people highly sensitive to light.
The tests measured UV light from the lamps and found the highest levels of UV radiation, measured 2cm from the lightbulbs, were equivalent to being outside in direct sunlight in the summer. The most immediate risk from the lightbulbs is a reddening of the skin similar to sunburn, but there is also a small increased risk of skin cancer associated with this, again similar to that of sunburn.
The risk of health problems from the lightbulbs was not so high that people should remove them from their homes. People are advised to avoid using open lightbulbs for long close work until the problem is sorted out. It has confirmed that the government will not be reviewing its strategy on introducing energy efficient lightbulbs.
1.The underlined word “equivalent” in paragraph 4 most probably means ______.
|
A．equal |
B．vital |
C．relevant |
D．harmful |
2.In order not to be harmed by the UV radiation from some lightbulbs, people should ______.
|
A．stop using eco-friendly lightbulbs at home |
|
B．avoid using open lightbulbs for long close work |
|
C．take care not to expose their skin to direct sunlight |
|
D．urge the government to ban the use of lightbulbs |
3.In the next part, the author would most probably further explain _____.
|
A．why people needn’t remove the lightbulbs from their homes |
|
B．how researchers have planned to sort out the problem |
|
C．how the government has responded to HPA’s discovery |
|
D．how long people should work close to the open lightbulbs |
4.We can learn from the passage that ____.
|
A．health officials issued a warning over common lightbulbs. |
|
B．jewellery makers should avoid working with the eco-friendly bulbs for more than one hour |
|
C．John O’Hagan did tests on the lightbulbs with some patients |
|
D．people are advised to avoid using open lightbulbs for long close work |
