4 Jim: (Questions 16 to 22) Read the conversation and select the best option for each question. Clerk: Can I help you? Yeah thanks do you have this blue shirt in a bigger size? I can only see “smalls” and "mediums" on the shelves... Clerk: Let me see... Sorry, but "large" is sold out. We don't have many long-sleeved shirts left because it's the end of winter, and that particular style has been popular. But we have it in an "extra-large," would you like to try it on? Jim: That sounds like it might be too big... Clerk: To be honest, these are slim-fit shirts, so an "extra-large" is more like a "large" in other styles. Jim: Oh really? OK, let me try it on... You're right, the fit around my body is perfect! But the sleeves are so long they cover my hands! Can you recommend anything else? Clerk: Hmmm... Do you mind if it's a different style? Jim: ( 16 ) I want a blue shirt, but apart from that I don't care much. Clerk: In that case, what about this short-sleeved blue shirt? It's "large," and it's from our Spring Collection. Jim: (17) Well, I know I said I didn't care much, but I'm not a fan of collars with buttons. I feel like I should be wearing a tie with those ones! Clerk: Ah, I see. Well, how do you feel about a patterned shirt? We have some nice blue shirts with stripes, dots, or flower designs. Jim: (18) Clerk: Sure. Here is a light blue one with thin stripes, and over there we have a dark blue one which comes in thin or thick stripes. 1:1-4h thick strines but that one only comes in dark blue, right? ined light

What would you do if you wanted to learn about something? A traditional way is to go to your bookshelf, pick up a dictionary or encyclopedia, and start turning pages. Now, however, you can turn on your computer, connect it to the Internet and start its search program. You just type in some keywords, click "search," and soon you will 5 have what you are looking for. 2 3) It seems as if anything you want to know can be found on the Internet. The range of information you can find on the Net varies from *gossip, to news, to the most advanced technological findings. Furthermore, the information is always fresh. New information is constantly added, past files are re-written, and *news reports are broadcast as they come in. 5) 3 What is being lost, though, is the joy of discovery. In many ways an Internet search is like a package tour. On a package tour, you generally know where you are going and see only what the *tour organizer has selected. Similarly, what you find in the Internet search is controlled by the site's owner or is the result of a computer program. On the other hand, turning the pages of an encyclopedia, as you look up an *entry, is more like wandering through a forest. You may accidentally find something interesting in the entry just next to the one you have been looking for. This may *stir up a new interest, which will eventually lead you into a totally different topic. 248 words>
