As water flows along the ground, it picks up sand, pebbles, even boulders. It uses them to gnaw at the sides and bottom of its channel, gradually loosening more earth.
By this process enormous amounts of mud and rock are moved from the land to the sea. Each year the Mississippi River carries 730 million tons of solid matter into the Gulf of Mexico.
This constant hauling of land into the sea is lowering the United States’ average height above sea level at a rate of about one foot every 9000 years. If erosion continues at the same rate, the United States will be worn completely down to sea level in about 23 million years.

D、both B and C
2.Flowing water gradually makes its channel ______.

C、wider
D、both B and C
3.Implied but not stated: ________
A、Millions of years ago the United States was higher than it is now

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.
