[单项选择]Invented by American computer scientists during the 1970s, the Internet has been embraced around the globe. During the network’s first three decades, most Internet traffic flowed through the United States. In many cases, data sent between two locations within a given country also passed through the United States.
Engineers who help run the Internet said that it would have been impossible for the United States to maintain its hegemony (统治权) over the long run because of the very nature of the Internet; it has no central point of control.
And now, the balance of power is shifting. Data is increasingly flowing around the United States, which may have intelligence--and conceivably military--consequences.
American intelligence officials have warned about this shift. "Because of the nature of global telecommunications, we are playing with a tremendous home-field advantage, and we need to exploit that edge," Michael V. Hayden, the director of the Central Intelligence Agenc

How Animals Keep Warm
Man has invented ways to keep warm, but how do animals defend themselves They cannot reason in the sense that man can, but nature has taken care of the animal kingdom by providing animals with special instincts (本能). One of these instincts is known as hibernation (冬眠).
"Sleeping like a dormouse (榛睡鼠)" is not only a common saying but is a reality. When winter comes, the dormouse and other hibernating animals have reached a well- nourished state. They eat very well in warmer days laying down fat in the tissues of their bodies and during hibernation this keeps them alive. Safe in their nests, or burrows (地洞), they sleep soundly until the warmth of spring arrives.
Bats, tortoises, snakes, frogs, even insects like butterflies, hibernate more or less completely. Some, like the squirrels (松鼠), sleep during coldest weather but are roused (弄醒) by a warm spell (暖流). During hibernation, th
A. It moves about to keep warm

[简答题]Flexible working hours were invented in Germany in the late 1960s, but reached Britain only in 1972. The system allows workers to start and finish work whenever they want, with only two requirements. Firstly, all workers must be present for certain "key" times in a day, and secondly, all workers must work an agreed total number of hours per week.
[单项选择]Until men invented ways of staying underwater for more than a few minutes, the wonders of the world below the surface of the sea were almost unknown. The main problem, of course, lies in air. How could air be provided to swimmers below the surface of the sea Pictures made about 2,900 years ago in Asia show men swimming under the surface with air bags tied to their bodies. A pipe from the bag carried air into the swimmer’s mouth. But little progress was achieved in the invention of diving devices until about 1490, when the famous Italian painter, Leonardo da Vinci, designed a complete diving suit.
In 1680, an Italian professor invented a large air bag with a glass window to be worn over the diver’s head. To "clean" the air a breathing pipe went from the air bag, through another bag to remove moisture, and then again to the large air bag. The plan did not work, but it gave later inventors the idea of moving air around in diving devices.
In 1819, a German, Augustus Siebe, develo
