Read the following passageand mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions. When you hear how I learned a foreign language, you have to remember a few things. In 1993, when I started learning English, no one had heard of the Internet. I wasn’t able to read websites on topics that I found interesting or follow blogs. And I have no idea how I decided which movies to see without my favourite movie review website. My reading practice was limited. All I had were a few books on sale locally. For listening practice, I only had the news and cartoons on cable TV. People bought and rented videos but in Poland there was no spoken English on them. The only way to hear that was to visit the movies. My dictionaries were all in book form until I received my first PC dictionary. It came on at least six disks and had unhelpful explanations and few example sentences. It doesn’t sound very useful but I loved it because of its ability to work with other programs and find English words more quickly. Today, computerized dictionaries have simple explanations and lots of examples. Now I can spend hours on the web, reading about my favourite topics, downloading up-to-date movies, emailing English-speaking friends and posting comments on forums. The word “up-to-date” means ____________________. A: oldest B: daily C: latest D: longest
