(new)Read the passage in your handout and find out the topic sentence of each paragraph. Then please draw a mind-map to show the structure of the passage.Consolidation Consolidation Almost everyone around us uses a phone. Phones provide a simple and efficient way to conduct work or deal with social arrangements from day to day. Several times in the course of a work day, you may be connected by your workmates, students or friends by means of phone. If you want a (an) appointment with your department head, you would usually call him and arrange a time with him. If you were unable to keep your appointment, or if you found you had to be late for it, you would phone and change the plan. In this way, no one wastes time waiting for someone who is not coming. If you want to buy something, you would “let your finger do the walking”. That is, you call ahead to make sure the store has what you need. If it is an expensive item, you might call several stores to compare prices so that you can buy the cheapest one. If you want to take a train or plane, after finding out the prices, you can call to book the ticket; if you want to shop for clothes after work, you might call to ask how late the store is open before you travel all the way there.Consolidation Phones are easily available. In streets, you can see public phones in which you feed coins to make a call.
Phones have automatic（自动的） answering services. If you are not at home or in the office, or don’t wish to be disturbed, you switch on a machine, which will answer the call for you. A pre-recorded message will say to the caller, “I’m sorry, I’m not available at the moment. Please leave your name and number and I will call you back as soon as possible.” It’s more efficient to leave one’s name and number than to waste their time calling again and again.1234Consolidation A hobby is something we are interested in doing in our spare time. Almost everyone has some kind of hobby. But the choices of hobbies are different from person to person. It all depends on many aspects including personal talents and interests. For example, some are fond of singing and playing musical instruments, such as piano, violin and guitar, while others prefer to surf the Internet for news or information, by which they can know what is happening around the world. Some like doing sports to keep healthy and build up their bodies, while others are keen on listening to music because when they’re in low spirits, it can drive away their unhappiness and cheer them up. Still some are crazy about traveling, believing that it provides them with more chances to know more about the different cultures and customs in different parts of the world, while others choose to stay alone and pick up a book and read quietly because in their view, reading can add to their knowledge and make them learn more about the outside world. Just as what is discussed above, the reasons why people choose their hobbies are various. For some people, they have too much time to spend and feel bored and meaningless, so they want to kill time by taking up a hobby. As for students, they usually have to deal with a great deal of homework every day and take endless examinations so that they can be admitted to their ideal university. In that case, hopefully they are likely to find a satisfying job after they graduate from a key university. But students need hobbies to relax and refresh themselves so as to keep the balance between study and play. All work and no play makes Jack a dull boy, as the saying goes.Consolidation SummarySkimming寻找主题句时，可观察句子
