The Channel Islands are a group of British-owned islands lying in the English Channel, 10 to 30 miles off the French coast, and 70 to 90 miles from the English coast. There are ten islands with a total land area of 75 square miles and a total population of 123,000. The three largest islands, Jersey, Guernsey, and Alderney, have long been known for the fine breeds (品种) of cattle that are raised on them and named after them.
In earliest known history the islands were considered part of Normandy, which was part of France, but the ruler of Normandy became king of England in 1066, and from then on the islands were looked upon as British land. English control was unbroken until World War II, when the Germans held the islands for five years.
Although people on the islands speak both languages and they are considered English, their customs are more French than English.

查看习题详情和答案>>For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone on outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships travelling through space, on the chance that someone may be receptive to such messages.
Scientists are using powerful radio telescopes to listen to signals from about 1,000 stars, all within 100 light years of earth. In addition, they will scan the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal that stands out from the background noise.
Of the 200 billion stars in the Milky Way galaxy(银河星系), scientist find that five percent are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution of life. Based on the inhabitable (that can be lived in) planets in our galaxy, most scientists agree that chances are likely that one or more of these planets supports some life.
However, many scientists wonder whether intelligent life exists on other planets. Some believe that twenty years of searching without any intelligible message shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.
Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family is about 20 billion years old. In that time, some scientists think it is likely that civilizations much more advanced than ours have developed. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.
