(36分)世界贸易是世界经济的晴雨表,各国在世界贸易中的地位是各国经济实力的体现。阅读下列材料,回答问题。

材料一  1400年到1800年,中国在整个世界经济中即使不是中心,也占据支配地位。它的这种更为核心的地位是基于它在工业、农业、运输和贸易方面所拥有的绝对与相对的更大的生产力。表明中国在世界经济中的这种位置和角色的现象之一是,它吸引和吞噬了大约世界生产的白银货币的一半,以平衡中国几乎永远保持着的出口顺差。至少直到1800年为止,亚洲,尤其是中国一直在世界经济中居于支配地位。

Online Degrees

Today, you can earn a degree from a major university without ever having sat in one of their classrooms. Many colleges and universities are offering online courses and degree programs now.

Online Learning Programs

With a computer and an Internet connection, you can earn a degree from home, work, or anywhere else for that matter. Online degree programs follow much the same routines as traditional learning, with a few twists. There are lectures, but they won't be in person. There are assignments (作业) , but you won't hand them to your instructor. In most situations, you are free to "go to class" when it fits your"schedule. If you get a phone call during class, you don't have to miss anything. If you get sick, you don't have to ask for someone's notes, and you just visit the lecture later.

You'll communicate with your instructor by e-mail, chat room and instant messaging. Your  classroom will live in a special software program. Contrary to popular belief, you will have close  contact with other students and the instructor.

Evaluating the Program

There are a lot of questions to ask before you make your selection, such as:

How do students interact with each other?

★Online programs can use chat rooms, instant messaging, teleconferencing, and video conferencing to communicate. The key is to find a program that has this interaction built into it and even requires it.

★What kind of reputation does the school have?

It may seem simple-a good school will have a good online program. This reputation,however, may not be as straightforward as you think. It's not uncommon for a great school to have a weak program or two. So you'd better look at the overall quality of the school and make a judgment.

The Employers' View

As more and more employees get online degrees and use them in the workforce(职场) ,  hiring managers will begin to feel more secure about the quality of education these people have.
