Access to Blocked Website

VOA Website

VOA website is excellent for English learners, as it provide short stories accompanied with voice records. So English learner is able to take advantage of its voice records to practice listening skills, while improving reading skills. On the website, there also is a section called VOA Special English, which aims to provide stories for people with intermediate level of English proficiency. After studied English through it for a certain time, I realize that although the words used in stories of special English is very easy, they have various meanings in different news, and are totally different from what I learn it before from Chinese - English dictionary. So I strongly recommend VOA Special English for you to extend usages of each word you have known in different situations.

Nice Websites been Blocked

It's a fantastic website providing free, interesting stories. However, because of some negative news about China provided by it, China has banned it, and people in China can't have access to it directly. It's not the only one banned by China , but also a number of good websites, such BBC news, Wikipedia. These websites provide a large amount of useful resources, which everybody could have rights to reach. It's a shame that the resources are unavailable to almost all Chinese people.

Thanks to the open source software called "TOR", we can use it as a proxy to access these banned websites. TOR is originally aimed at offering people a safer Internet environment, as taking advantage of it allows people to have activities on Internet anonymously. This means it's difficult for someone else, such as hacker, to trace where you are from, what you are doing on Internet, avoid exposure of private information.

Advantages of TOR

1. Bypass the firewall in some countries
Basically, TOR works in a P2P way to fetch data from destination. In this procedure, it isn't connecting to target website directly, instead it achieve that through set up a link chain which is made up by links between several TOR users. Therefor, TOR user is able to have access to blocked website with the assistance of other TOR users. The original purpose of TOR is to safeguard information exchanging on Internet, So there are many users would like to use it to ensure safety of their Internet activities. This means as we want to use it as a web proxy to bypass firewalls, we don't need to worried about the reliability of the proxy, because there are so many people using it, providing plenty of points acting like proxies. Actually, it is not just one proxy, but a plenty of proxies.

2. Speed up loading pages
Each country has certain amount of Internet speed limitation to connect to foreign countries. When a large number of data transfer to foreign countries, the transfer speed of data to certain country for each domestic Internet users would be reduced. As TOR is able to connect to nearly every country in the world, it is capable to find the most fast way through other countries to destination, which help balance the heavy load of data to specific country.

The most recent version of TOR have ability to select fast users to connect to, which could promote the speed of transferring data. So when you are browsing some foreign websites, which is loading slowly, try to access it with TOR. It may surprise you.
