Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
NEW YORK--Every so often, late at night, David Woodland steals away to the den of his home in Aberdeen, Washington, so that he can check stock prices on the Internet.
Mr. Woodland, a 78-year-old retired insurance salesman, delights at how with the click of a mouse, he can tap into the facts and fortunes of Wall Street. "If I get a bright idea late at night," Mr. Woodland said, "I go into the office, fire up the computer and put a buy or sell order in."
While on-line trading is popularly regarded as the province of any traders in their 20s and 30s, jumping in and ont of the market to make quick profits, it is now being invaded by millions of people like Mr. Woodland--senior investors who bring much larger accounts and more stability to this fast-growing corner of the markets,
The low cost of doing business on-line--now as little as $7 a trade--and the excitement of riding a bull market are the lures (诱惑) for many older investors--just as they are for the young. They are dismissing their full-service brokers, who offer research and advice but often charge more than $100 a trade, and instead are picking their own stocks, after downloading companies' annual reports and other research basics.
"These things are incredible tools, now in the hands of an individual investor," said Carol Potts, 56, a retired crafts designer in Santa Barbara, California. "There's no reason for me to have financial advisers. I am very analytical, and I like to get involved in research."
According to a survey this fall of 630 people over 50 by Charles Schwab & Co., many older investors say the Internet has made them more confident about their investments and more willing to trust their own judgment. But such confidence may also cause some to gamble away their retirement nest eggs, financial experts warn. "If stocks enter a bear market, it could prove disastrous for retirees, who are so dependent on their savings."
The main idea of the passage is that ______.
A．on-line trading attracts more and more retirees to get involved
B．on-line trading is more suitable for the old than for the young now
C．on-line trading enables the retirees to get rid of their advisers
D．on-line trading offers incredible tools and high profits to investors
