　　Passage Three

　　Alaska, which was called Russian America before it was sold to U. S. A. ,joined the union as the forty-ninth state in 1959.

　　Alaska is now the largest of all the 50 states of the U. S..

　　It was in 1867 that President A. Johnson's Secretary of State(国务卿) ,Seward bought Alaska from the Russians at a cost of 7.2 million. The buying of the huge northern land mass seemed at first something foolishly done. Not only was Alaska difficult to reach, but it was also hard to bye in, and it appeared to have no importance in time of war. Besides, there are volcanoes there as Alaska hes on the Pacific" ring of fire". In Alaska large treeless areas are covered with snow all the year. For these reasons the buying of Alaska was called "Seward's Fooly" at that time.

　　However, in 1896 gold was found in Alaska, and people poured tin to the land quickly. Since then other important natural resources were discovered, including oil. Soon people changed their thinking about "Seward's Fooly". But most people visit Alaska in order to see the endless beauty of nature that the northern land discloses to them. For instance, there are a- bout 11,000 islands in Alaska. And in a certain area of Alaska the sun does not set for 82 days

　　Passage Five

　　"Family"is of course an elastic word. But when British people say that their society is based on family life,they are thinking of "family" in its 'narrow,peculiarly European sense of mother, father and children living together alone in their own house as an economic and social unit. Thus, every British marriage indicates the beginning of a new and independent family-- hence the tremendous importance of marriage in British life. For both the man and the woman, marriage means leaving one's parents and starting one's own life. The man's first duty will then be to his wife, and the wife's to her husband. He will be entirely responsible for her financial support, and she for the running of the new home. Their children will be their common responsibility and theirs alone. Neither the wife's parents nor the husband's, nor their brothers or sisters,aunts or uncles, have any right to interfere with them--they are their own masters.

　　Readers of novels like Jane Austen's Pride and Prejudice will know that in former times marriage among wealthy families were arranged by the girl's parents, that is, it was the parents'duty to find a suitable husband for their daughter, preferably a rich one, and by skillful encouragement to lead him eventually to ask their permission to marry her. Until that time, the girl was protected and maintained in the parents'home, and the financial relief of getting rid of her could be seen in their giving the newly married pair a sum of money called a dowry. It is very different today. Most girls of today get a job when they leave school and become financially independent before their marriage. This has had two results. A girl chooses her own husband, and she gets no dowry.
