Question: Article: British writer John Bunyan was born at Elstow, Bedfordshire, England, in November, 1628. His father was a maker and mender of pots and kettles, and the son followed the same trade. Though he is usually called a tinker, Bunyan had a settled home and place of business. He had little schooling, and he describes his early surroundings as poor and mean. He became much interested in religions, but it was only after a tremendous spiritual conflict, lasting three or four years, that he found peace. His struggles are related with extraordinary vividness and intensity in his "Grace Abounding to the Chief of Sinners." His writing began with a controversy against the Quakers , and shows from the first the command of a homely but vigorous style. Like most working men at the time, Bunyan had a deep hatred for the corrupted, hypocritical rich who accumulated their wealth "by hook and by crook." As a stout Puritan , he had made a conscientious study of the Bible and firmly believed in salvation through spiritual struggle. Bunyan's style was modeled after that of the English Bible. With his concrete and living language and carefully observed and vividly presented details, he made it possible for the reader of the least education to share the pleasure of reading his novel and to relive the experience of his characters. Bunyan's works include Grace Abounding to the Chief of Sinners (1666), The Life and Death of Mr. Badman (1680), The Holy War (1682) and The Pilgrim's Progress (1684). The Pilgrim's Progress is the most successful religious allegory in the English language. Its purpose is to urge people to observe Christian doctrines and seek salvation through constant struggle with their own weaknesses and all kinds of social evils. It is not only about something spiritual but also bears much relevance to the time. Its predominant metaphor -- life as a journey -- is simple and familiar. The objects that Christian meets are homely and commonplace, and the scenes presented are typical English ones, but throughout the allegory a spiritual significance is added to the commonplace details. Here the strange is combined with the familiar and the trivial joined to the divine, and, a rich imagination and a natural talent for storytelling also contribute to the success of the work which is at once entertaining and morally instructive. "The Vanity Fair," is an excerpt from The Pilgrim's Progress. The story starts with a dream in which the author sees Christian the Pilgrim, with a heavy burden on his back, reading the Bible. When he learns from the book that the city in which he and his family live shall be burnt down in a fire, Christian tries to convince his family and his neighbors of the oncoming disaster and asks them to go with him in search of salvation, but most of them simply ignore him. So he starts off with a friend, Pliable. Pliable turns back after they stumble into a pit, the Slough of Despond. Christian struggles on by himself. Then he is misled by Mr. Wordly Wiseman and is brought back onto the right road by Mr. Evangelist. There he joins Faithful, a neighbor who has set out later but has made better progress. The two go on together through many adventures, including the great struggle with Apollyon, who claims them to be his subjects and refuse to accept their allegiance to God. After many other adventures they come to the Vanity Fair where both are arrested as alien agitators. They are tried and Faithful is condemned to death. Christian, however manages to escape and goes on his way, assisted by a new friend, Hopeful. Tired of the hard journey, they are tempted to take pleasant path and are then captured by Giant Despair. Finally they get away and reach the Celestial City, where they enjoy eternal life in the fellowship of the blessed.

Question: Article: In 1901, H.G. Wells, an English writer, wrote a book describing a trip to the moon. When the explorers landed on the moon, they discovered that the moon was full of underground cities. They expressed their surprise to the "moon people" they met. In turn, the "moon people" expressed their surprise. "Why," they asked, "are you traveling to outer space when you don't even use your inner space?" H.G. Wells could only imagine travel to the moon. In 1969, human beings really did land on the moon. People today know that there are no underground cities on the moon. However, the question that the "moon people" asked is still an interesting one. A growing number of scientists are seriously thinking about it. Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The "Chunnel", a tunnel connecting England and France, is now complete. But what about underground cities? Japan's Taisei Corporation is designing a network of underground systems, called "Alice Cities." The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome would cover the whole city. Supporters of underground development say that building down rather than building up is a good way to use the earth's space. The surface, they say, can be used for farms, parks, gardens, and wilderness. H.G. Wells' "moon people" would agree. Would you?
Answer: lived in so many underground cities

Answer: The explorers in H. G. Wells' story were surprised to find that the "moon people" _ .

Question: Article: When dinning in restaurants, Americans usually order drinks first, then soup, salad, main course or entree , and dessert at last. This is somewhat a different order way from that in Europe. Until about the middle of the nineteenth century, Americans didn't have to worry about whether the salad came before or after the main course since they didn't eat salad at all. Chomping on greens was once considered sissy , and Americans preferred to get their greens indirectly, after they had been processed by rabbits or deer. The shift of public taste toward the salad may be attributed to New York's Delmonico brothers, who originally introduced smorgasbord from Europe, and served it in their restaurant. Such novelties became so popular that by the end of the nineteenth century, the Waldorf salad has swept the country. Europeans still chomp on greens after the main course, as a way of clearing the palate , and being ready for the cheese. Why Americans eat their salad first is uncertain. The following joking suggestions might make sense: The custom may be related to the slimming craze, for "salad first" may fill you up without any worry about fattening; to avoid customers' impatience with waiting, the restaurant serves salad first to keep them busy while the main courses are being prepared; eating raw food while one is waiting for the cooked food may be a way of announcing that one is not wasting time, which is seen as a virtue; probably unfair to the restaurant, this custom has been encouraged by the merchant as trick-the meagerness of a meal is less noticeable if it comes after "free" salad-after all, rabbit food is much cheaper than the rabbit.
