Looking to improve your language skills, but you dont have the time to go abroad to attend

school？ More and more universities around the world are offering opportunities for students to getdegrees online (distance education) from the comfort of their own homes, and many of these colle-ges and universities are accredited (官方认可的), meaning that they have met certain standards ofexcellence. If you decide to take language courses online (or any subject for that matter), be sure thereare advantages in studying online. Its costs are usually lower, and you can study at your own pace(节奏), and you can easily get the materials 24 hours a day from almost any computer in theworld. However, you wont get the human interaction (互动) of meeting people face to face, asyou would if you were attending a school abroad in person. On the other hand, the advantages of going abroad may include day-to-day chances to learn anew culture, to meet new friends with whom you can use and practice the language, and to see dif-ferent parts of the world. However, there may be a number of disadvantages for some students, in-cluding high costs, time away from ones school, family, or work life, and difficulty in gettingused to a new culture and way of life. Whatever you do, consider a distance education program that meets your educational needs, iswhat you can afford, and equally important, provides you with chances tobeyond the class-room through cultural and educational activities. 根据材料请回答下列各 What is the purpose of the author in writing the text？
