I saw him seated under the tree,thinking.为什么不用seating?

The young woman seated next to us at the sushi(寿司) bar gave off an alien air; her looks and style, we thought, made it likely that she was not American born.
But then she spoke in perfect American English, with the typical characteristic of many young Californians.
As it turns out, however, she wasn’t from these parts after all; she was born in Iran and spoke only Farsi(波斯语) until her arrival here two years ago. What classes, we wondered, had she attended to learn the language so well?
“I didn’t,” she said. “I used Rosetta Stone.”
Those yellow boxes sold at shopping-mall and airport newspaper stands may be the most recognizable example of PC-based language learning, but it certainly isn’t the only one.
With the growth of broadband connectivity and social networks, companies have introduced a wide range of Internet-based language learning products, both free and fee-based, that allow students to interact in real time with instructors in other countries, gain access to their lesson plans wherever they are in the world, and communicate with pen pals who are also trying to remember if bambino means baby.
Learning a language sometimes seems as difficult as dieting. The solution is to figure out how to stay interested after the curiosity wears off.
To fight against boredom, online language programs have introduced crossword puzzles, interactive(交互的) videos and other games to reward users for making progress.
Online courses are either fee-based, free or a combination. Starter kits(入门套件) of fee-based programs may cost just a few hundred dollars, but the cost to reach higher levels of comprehension and speaking can easily be $1,000.
While that may sound expensive, language company managers say it isn’t; college courses often cost many thousands of dollars to reach the same level.
So, cost aside, how do you choose which program to use? The answer is that one size doesn’t fit all.
