Ben knows that this day honors an important man, but Ben does not feel connected to him. However, the small-wor
4、ld theory (理论) connects Ben to Dr. King. Bens mom (0) has a close friend, Amy (1). Amys uncle, Mark (2), once met and spoke to John Carter (3), the son of President Jimmy Carter (4). Jimmy Carter knew Dr. King (5). In a way, Ben is only “five people away” from Martin Luther King Jr.The small-world t
5、heory says that everyone in the world is connected through a short chain (链条) of people they know. Another name of this chain is degrees of separation. Each degree is a step that separates a person from someone he or she does not know. There are zero degrees of separation between a person and the pe
6、ople he or she knows directly. This means that there are zero degrees between Ben and his mom. There is one degree of separation when just one person separates someone from a person he or she does not know. Ben knows his mom, but he hasnt met her close friend Amy. Therefore, Ben is one degree away f
7、rom Amy. As the chain continues, Amys uncle, Mark, is two degrees. John Carter is three degrees, and his father is four degrees. Dr. King is five degrees away from Ben. The theory says that there are no more than six degrees of separation between any two people in the world.The small-world theory ha
8、s a lot to do with math. The theory assumes (假定) that each person knows 100 people. Each one of those 100 people knows 50 different people. Each of those 50 people knows another 50 people, and so on. When someone continues the calculation to six degrees, it is like this: 100 50 50 = 31.25 109. This
9、number is greater than 31 billion (a billion = a thousand million). There are over 6 billion people in the world. These numbers show it is possible that six degrees of separation could include everyone in the world.Does the small-world theory work? No one has ever proved it. Maybe the theory just in

13、act, sometimes the reading is so difficult that it almost seems like a foreign language. In a way, it is the language of science. You should not expect to be able to read a difficult science passage the same way you read an interesting story; you should not expect to read it easily and all at once.
14、Instead, you may have to read it several times through, catching on the meaning of difficult words, going back over difficult sentences, and finally putting the whole thing together. Do not be discourages if the whole passage dont make sense to you at first. You need to pick it apart patiently until
15、 you can understand it.These are the steps to follow when you are reading something difficult: 1. Start to read normally until you run into a sentence that doesnt make sense to you. 2. When a sentence doesnt make sense, go back and read it again more slowly. 3. Look for any word you dont know in the
16、 sentence. Try to understand their meanings using word parts and context clues(上下文线索). If necessary, look them up in the dictionary. 4. Look at the next few sentences to see if they explain more about the sentence you are working on. Do not read very much farther ahead until you understand what is b
17、eing said. 5. Finally, read the sentence again. Try to put it into simpler words. 6. Read through the passage once. Try to understand all the hard parts well. Then read the whole passage once more at a usual speed. This helps you to put all ideas together.The stops sound a lot harder than they are.
18、It is really just the normal way good readers understand anything that is difficult to read. After you have done the best you can this way, you should always feel free to ask for help from your teacher, if you have one.54. The underlined phrase “run into” means _.

If you want to say that its not safe to land, put your arms in the air and move them to one side.Smoke signalsThe smoke from a fire can be seen from far away, so its a good way to draw attention. If the weather is dry,
23、 it isnt hard to start a fire. Remember, however, that fires can be very dangerous if they get out of control. Never light a fire unless youre sure that it cant spread. .If the ground is dark, light smoke can be seen more easily. Green grass and leaves produce light smoke.Ground-to-air signalsIts a
24、good idea to build some signals, too. Use large pieces of wood to make the symbols(标记). If you cant find any wood, use earth. Some useful symbols are:F “I need food and water”.II “I need medicine”.I “I am badly hurt”.X “I am unable to move from here.”Pilots repliesIf the pilot lowers the planes wing
