[单项选择]

Actually, though, America, the "land of immigrants", has always had people of many different nationalities and languages. The 1990 census indicates that almost 14% of Americans speak a non English language at home. Yet only 3% reported that they spoke English "not well" or "not at all". That means that slightly more than one out of 10 Americans could be considered bilingual.
Besides that, many high school, college students, and even some elementary school students are required to take a foreign language as a part of their curriculum. In addition to old standbys like Spanish, German and French, more and more students are opting for Eastern European and Asian languages. Of course, not all students keep up their foreign language abilities. As the old saying goes, " If you don’t use it. " But still, a growing number of Americans are coming to appreciate the benefits of being multilingual.

[单项选择]How to Retire Earlier
It’s every working staff’s dream: saying goodbye to the daily grind while you still have your own teeth. In our early retirement fantasies, we’re traveling the world, healthy and in the prime of our lives, visiting those hard-to-pronounce countries we’ve always talked about and sampling the finest local fare.
Retirement-related Problems
Surveys show that more than half of workers between the ages of 30 and 50 plan to retire before they’re 60. But there’s only one problem with this wishful thinking: Retiring early is easy, but making your money last is hard.
One problem with saving up for early retirement is that we tend not to think beyond those first few glorious years of good health and full checking accounts-we don’t do the long-term math. If the average male life expectancy is 75.2 and we retire at 55, then our savings, and stock market investments need to last for 20 years. And what if we live even longer than average A. To maintain a good figure.
B. To earn as much money as you can now.
C. To work out a detailed plan of world travelling.
D. To know exactly the amount of your wealth.
