For most topics it’s the best way f or him to find information, and for many topics it’s the only source he needs, especially if he’s in a hurry. He uses it as a research tool, both in his work as a computer expert and in his hobby of studying the financial world, and he uses it for networking with colleagues. The only problem he has with the Web is that it contains so much information. This means he must avoid being sidetracked by irrelevant information or misled by inaccurate information that he can’t substantiate.2.Check the answers of Ex.12 ,13 and 143.
