In old times, people wondered about the changes of seasons, about the stars, the moon and the sun. They could not explain these things, and so they made up "why" stories about them.
The ancient Greeks told about Demeter, the goddess of agriculture, who kept the earth all green all year. One day her daughter Persephone was kidnapped(绑架) by Hades, the god of the dead. Demeter was so unhappy that she let everything on earth die. At last, Hades permitted Persephone to return to her mother for part of the year. During that period, everything on earth grew well again. One season, however, Persephone had to stay with Hades. During that season, the earth remained cold and bare. So winter was explained.
American Indians told of an old woman who stood on a high mountain. When the moon was full, she cut off bits of it and threw these bits about the sky. This explained where the stars came from, and why the moon became small.
Hundreds of stories like these were passed down by word of mouth. Later, these stories were put in books. Today we read them not for explanation of natural wonders but for enjoyment.
The ancient Greeks explained ______.
A．how the year was divided into four seasons
B．how Demeter's daughter was saved
C．why they loved Demeter and hated Hades
D．why they had a winter season

In cities across the United States, old factories, warehouses, schools railroad stations and other buildings are being renovated for new uses.City planners and private investors are finding the good buildings, no matter how old, can be remodeled for new purposes.“If you’d asked someone four or five years ago whether he’d rent an apartment in an abandoned piano factory of clothing warehouse, he’d have thought you were crazy,” says a New York architect.“Today, many people are eager to do it.” The renovating may include a former city hall or courthouse changed into offices; a bank or church changed into a restaurant; or , as in Plains, Georgia, a railroad station used as a center for a presidential campaign.
Only a few decades ago, renovation was unpopular and generally far more expensive than taking down abandoned building and string from the beginning.A change began in the 1960s with a number of well-advertised projects.They included Ghirardelli Square in San Francisco, where an old chocolate factory was restored and made into shops and restaurants, Trolly Square in Salt Lake, where unused warehouses were made into artists’ studios and apartments.
What caused the change？ “One reason is nostalgia,” a San Francisco builder suggests.“Maybe old is better than new, many people are saying.Feelings about preserving attractive or historic buildings have changed a great deal.” A second cause is economy.The cost of tearing down an old building and constructing a new one from nothing now has risen to the point where it is often less expensive to fix a solid older structure.Also builders realize that fixing up an existing building often requires no new permits, sewer lines, or water connections.
Even when the costs of restoration are the same as or a bit more than the costs of putting up a new building, fixing the old building may be better.A Boston architect says The advantage comes when you can develop a final project that is more desirable than a new building – one with the right location, more space, more floor area, a special character, materials of a particular quality.” Gradually, architects and builders are developing knowledge about renovation and preservation, bringing imagination and creativity to the job.

A.has had a long history

18.“Nostalgia” in the 3rd paragraph most probably means________.
A.being conservative
