The year was 1985. Ronald Reagan was president. Mikhail Gorbachev became leader of the USSR. Back to the Future was boffo at the box office. “Born in the USA” was climbing the charts. Philanthropy(慈善业) and pop culture combined with LiveAid and “We Are the World.” And “.com”, which few people outside of the military or universities knew, came into this world.

Looking back, few could have predicted “.com” would become one of the biggest cultural touchstones of the century. In March 1985, the Information Sciences Institute at the University of Southern California assigned the first .com domain address to symbolics.com. That seemingly nominal(象征性的) event set into motion forces that would change our world forever.

.com wasn’t the birth of the Internet, but it was the budding computer network’s coming-out party. It made it pretty and inviting. It did away with the need to have complex “maps” that were the equivalent of writing a phone number on your hand, and opened it up for a mainstream audience.

After 1985, all it takes is a simple .com name to get into business. “.com” became part of our daily lexicon and drove its own economic boom and depression. It helped create a whole new family of industries, facilitated global commerce and connected people around the world in ways never before possible.

It’s now 2010. Barack Obama is president, thanks in part to his smart use of the Internet. There is no USSR. A computer-generated Avatar has set new box office records. “TiK ToK” tops the charts. We’re sending robots to find water on Mars. And that once-obscure computer communications system is one of our civilization’s most prominent features.

A. It gave birth to the Internet.

B. It combined politics, entertainment and space science.

C. It made the Internet accessible to ordinary people.

    Once Lu Xun spoke to the young men about the study of foreign languages. He said: "You must not give

up studying foreign languages for even a day. To master a language, words and grammatical rules are not

enough. You must do a lot of reading. Take a book and force yourself to read it. At the same time, turn to

dictionaries and memorize grammatical rules. After reading a book, it's only natural that you won't understand

it all. Never mind. Put it aside, and start another one. In a few months or half a year, go over the first book

again; you are sure to understand much more than before... Young people have good memories. If you

memorize a few words every day and keep on reading all the time, in four or five years, you will certainly be

able to read works in the foreign language."
