Four out of five parents worry that their children will become addicted to Facebook, according to a study.

    Eighty percent believe social networking sites such as Facebook and Twitter have the ability to take over their children’s lives. One in three parents, meanwhile, believe the Internet has the power to ‘rewire’ brains(“改装”大脑)without a person’s knowledge and think their children are in danger from the web.

    The extraordinary findings come from a poll of 1, 000 parents carried out by the Nominet Trust, an organization that promoted Internet projects which address social disadvantages.

    However, Nominet said their findings fly in the face of neurological(神经学上的) evidence. The Trust worked with neuroscience and education expert Dr Paul Howard Jones, who analysed researches on the Internet and society. The report—The Impact of Digital Technologies on Human Well-being—concluded that there is no neurological evidence to suggest that the Internet is more effective at ‘rewiring’ our brains than other environmental influences. It also found that the Internet is a valuable learning resource and all forms of learning cause changes within the brain.

    There have been reports that the use of the Internet with its vast resources of information is changing the way people think and affecting their ability to concentrate. But Nominet said that’s scare-mongering（危言耸听）and the misinformation about the Internet use can potentially deny（否定）its benefits to people, in particular parents who are worried about the effects on their children’s development.

    The report also found that social networking sites, in themselves, are not a special source of risk to children, and are generally beneficial as they support existing friendships. In addition, playing action video games can improve some visual processes and motor response skills, while computer-based activity provides mental stimulation, and can help slow rates of cognitive decline.

    Tony Wrench and his wife Faith, wearing the traditional woolly jacket, have set up their home in the shadows of Preseli Mountains.

    They built the house in the winter of 1997 with the dream of living what they call“low-impact lives”. Their dream is to get close to nature, have little pollution and prove they can change the world. But their action was stopped almost a year later by the local government. Eventually, a new rule about environment protection was brought and the government encouraged the couple to carry on their “low-impact lives”.

    The completed house is built around a frame of 200 firs(冷杉木)and made entirely of natural materials, in a style that is part-native American, part-ancient Celt. Mr. Wrench said this house was more like a sort of large basket.  The most expensive part of the building was the rubber (橡胶 ) pond-liner for the roof at ￡650—all in it cost a grand total of￡3, 000, the labor being supplied by the couple and a few good friends. The idea is to try to make the most of the natural resources around them, reducing their impact as much as possible on the environment.

    Electricity is generated from three solar panels on the roof and a small windmill. Food is mostly home-grown (自产的) and they even make their own wine from a vine（藤）on the roof. Drinking water comes from the mountain stream and hot water is more or less on-tap through a back-boiler system fixed up to the back of the fire by the old whisky barrel(桶).

    Waste is dealt with by being rotted, which in turn provides fertilizer for the corns and vegetables etc. . They are by no means tired of life; on the contrary they like it. Mr. Wrench in particular likes nothing better than a nice hot bath. They wait for enough wind to charge the laptop so they can watch a DVD in the evening.

    Their life is not a challenge of existence; they say—just an attempt to keep their footsteps on the planet as light as possible.

55. What can we know from the passage?

A. Mr. Wrench planned to run a wine factory when he was young.

B. Mr. Wrench and Faith love their house and have been in it for twenty years.

C. Mr. Wrench and Faith’s behavior once was forbidden by the local government.

D. Mr. Wrench and Faith can’t watch TV in their house because there’s no electricity.

56. From the text we learn that the couple’s house______.

A. cost them 3, 650 pounds in all

B. is only made of about 200 firs

C. is not strong enough to resist the wind

D. was built by them and some of their friends

57. The food that the couple eat is mostly______.

D. sold to other farmers

    When we talk about boomerangs (回飞棒), we usually mean the curved devices(弯曲的设备) that return to you when you throw them, but there are actually two different kinds of boomerangs: the returning type and the non-returning type. Most returning boomerangs measure 30 to 60 cm across. Non-returning boomerangs are usually heavier and longer; typically 1 meter or more across, usually used as hunting weapons.

    Experts believe the invention of boomerangs was mostly a matter of trial and error. First let’s consider how a primitive hunter might have come up with a non-returning boomerang. In nature, there are plenty of sticks that are bent in a curve like a boomerang, and people probably threw the sorts of sticks all the time. Because of the stabilizing motion of the two branches of the stick, this sort of stick would have stayed in the air longer and would have been easier to send in the desired direction. Primitive humans noticed this and so they started specifically seeking out bent sticks. Then they started selecting the best curved sticks (thinner, longer ones work better) and were soon making some changes so they were especially suited for taking down birds and animals.

    Experts aren’t really sure when and where people first developed returning boomerangs, but the Aborigines of Australia are generally credited with the invention. The Aborigines used non-returning boomerangs, which they called kylies, widely in hunting, and the theory is that at some point, one or more Aborigines used a kylie with the particular shape of a boomerang and noticed that it traveled in a curve. That might have been a pure accident.

    The amazing flight pattern of the new discovery didn’t really help out much in hunting—it actually made it harder to aim accurately—but it was, of course, really cool. Evidently, the Aborigines perfected the boomerang design and throwing technique for the simple pleasure of it. However, the boomerang did have some limited use in hunting. The Aborigines would set up nets in trees and then throw the boomerang into the air while making a hawk（鹰）call. This would scare birds so they would fly down into the nets.

51. What does the second paragraph mainly tell us?

A. How primitive men invented returning boomerangs.

B. How non-returning boomerangs were invented.
