第3题：

In the author’s opinion, employees should _____.

［A］ invest in company stock to show loyalty to their employer

［B］ get out of their own company’s stock

［C］ wait for some time before disposing of their stock

［D］ give trust to a particular company’s stock


正确答案：B

 本题考查作者观点。第五段中作者提到，年青的雇员没有选择，只能等到50或55岁才能卖掉公司的股票以作为配送缴款（matching contribution）。第六段则提到，而老雇员在能够退出（getting out）的时候却没有。60岁和以上的人中1/3的人选择公司股票作为他们3/4的投资计划。该段末句作者连续用几个问号对这种做法进行了质疑：难道他们疏忽了？过度忠诚？疾病？由此我们可推出作者的观点是反对投资自己公司的做法。因此［B］项正确，排除［A］项。

第七段首句作者则提到，投资者不应该完全信任任何一家公司的股票。因此［D］项是作者反对的。［C］项文中未提。词汇补充：to a fault“过度地”，如generous to a fault（过度慷慨）。

第4题：

The Stock Exchange is in turmoil following a huge wave of selling.

A: service
B: danger
C: disorder
D: threat

答案：C
解析：
句意：在出现了大波的抛售之后，证券市场出现了混乱。画线单词turmoil意为“混乱”。A项service意为“服务”;B项danger意为“危险”;C项disorder意为“混乱，凌乱”，与画线单词意义相近;D项threat意为“威胁”。故本题选C。

What's NASDAQ?

NASDAQ is a familiar but strange name for people.We often learn its news via different kinds of media,though quite a lot of people can not tell what exactly it means.
NASDAQ,short for the National Association of Securities Dealers Automated Quotations system,is one of the largest market in the world for stocks trading. The number of companies in NASDAQ is more than that of the other stock exchange in America,including the New York Stock Exchange(NYSE)and the American Stock Exchange(AMEX).
Most of the companies listed on NASDAQ are smaller than most of those on the NYSE and AMEX.NASDAQ has become recognized as the home of new technology companies,especially computer and computer-related businesses.Trading on NASDAQ is initiated by stock brokers acting on behalf of their clients.The brokers negotiate with market makers who concentrate on trading specific stocks to reach a price for the stock.
Different from other stock exchange,NASDAQ has no central location where trading takes place.Instead,its market makers can be found all over the country and make trades by telephone and via the Internet. Since brokers and market makers trade stocks directly instead of on the floor of a stock exchange,NASDAQ is called an over-the-counter market. The term over-the-counter refers to the direct nature of the trading,as in a store where goods are handed over a counter.
Since its foundation in 1971,the NASDAQ Stock Market has been the innovator. As the world's first electronic stock market,NASDAQ long ago set a precedent for technological trading innovation that is unrivaled.Now poised to become the world's first truly global market,the NASDAQ Stock Market is the market of choice for business industry leaders worldwide.By providing an efficient environment for raising capital NASDAQ has helped thousands of companies achieve their desired growth and successfully make the leap into public ownership.
