There have been many books written during the past decade on the topic of mathematical modeling; all these books have been devoted to explaining and developing mathematical models, but very little space has been given to how to construct mathematical models, that is, how to take a real problem and convert it into a mathematical one. Although we appreciate that we might not yet have the best methods for teaching how to tackle real problems, we do at least regard this mastery of model formulation as a crucial step, and much of this book is devoted to attempting to make you more proficient in this process.
Our basic concept is that applied mathematicians become better modelers through more and more experience of tackling real problems. So in order to get the most out of this book, we stress that you must make a positive effort to tackle the many problems posed before looking at the solutions we have given. To help you to gain confidence in the art of modeling we have divided the book into four distinct sections.
In the first section we describe three different examples of how mathematical analysis has been used to solve practical problems. These are all true accounts of how mathematical analysis has helped to provide solutions. We are not expecting you to do much at this stage, except to read through the case studies carefully, paying particular attention to the way in which the problems have been tackled—the process of translating the problem into a mathematical one.
The second section consists of a series of real problems, together with possible solutions and related problems. Each problem has a clear statement, and we very much encourage you to try to solve these problems in the first place without looking at the solutions we have given. The problems require for solution different levels of mathematics, and you might find you have not yet covered some of the mathematical topics required. In general we have tried to order them, so that the level of mathematics required in the solutions increase as you move through the problems. Remember that we are only giving our solutions and, particularly if you don't look at our solution, you might well have a completely different approach which might provide a better solution.
Here, in the third section, we try to give you some advice as to how to approach the tackling of real problem solving, and we give some general concepts involved in mathematical modeling. It must, though, again be stressed that we are all convinced that experience is the all-important ingredient needed for confidence in model formulation. If you have just read Sections I and 11 without making at least attempts at your own solutions to some of the problems set, you will not have gained any real experience in tackling real problems, and this section will not really be of much help. On the other hand, if you have taken the problem solving seriously in Section Ⅱ, you might find the general advice give
A．solving problems in real life with mathematics
B．the application of mathematics in problems related to mechanics
C．its ability to describe various situations
D．the construction of mathematical modeling

disappears and recuperation begins. The tired mind gathers new energy, and the memory improves.
Some adults require little sleep; others need eight to ten hours in every twenty-four hours. Infants sleep sixteen to eighteen hours daily, the amount gradually diminishing as they grow older. Young students may need twelve hours; university students may need ten. A worker with a physically demanding job may also need ten, whereas an executive working under pressure may manage on six to eight. Many famous people have little sleep. Napoleon Bonaparte, Thomas Edison and Charles Darwin apparently averaged only four to six hours a night.
Whatever your individual need, you can be sure that by the age of thirty you will have slept for a total more than twelve years. By the age you will also have developed a sleep routine: a favorite hour, a favorite position, and a rule you need to follow in order to rest comfortably.
Investigators have tried to find out how long a person can go without sleep. Several people have reached more than 115 hours nearly five days. Whatever the limit, it is absolute. Animals kept awake for from five to eight days have died of exhaustion. The limit for human beings is probably about a week.
(1).By writing this passage, the writer intends to tell us that _______.
A、sleep is important for good mental and physical health
B、a light sleep is as restful as a deep sleep
C、memory is improved during sleep
D、sleep is relatively unimportant for human beings
(2).The amount of the sleep required may ___.
A、tire an individual mind
B、help infants grow older
C、apply pressure on an executive
D、that they didn’t sleep long
(3).If a person is not allowed to follow his own sleep routine, he will probably _____.
A、never fall sleep
B、not sleep well
C、lost his memory
D、begin to daydream
(4).The author implies that if human beings are kept awake for more than a week the result _____.
A、is hard to imagine
B、will probably be a mental breakdown
C、is difficult to describe
D、will probably be dead
(5).From the amount of sleep Napoleon, Edison, Darwin required, we can conclude ___.
A、 that they were famous
B、 that they were executives
C、 hat they were intelligent
D、 that they didn’t sleep long
A.the thesis or the plan of development

Door-knocking is the most effective way of making face-to-face community contact, but it has become a lost art. With the recent focus on customer privacy, door-knocking seems like an intrusion into other people's lives. But those who try it for the first time are usually surprised by the pleasant reception they receive. Here are some suggestions that will help you promote your services face-to-face.
BEFORE YOU GO OUT
Begin with a door hanger
Try leaving a door hanger two days before you go door knocking. It should briefly describe the project and say that someone will be around in person.
Wear an official name tag
Door-knockers should wear name tags with the logo of their organization. The best name tags will also include a color photo and the name of the caller.
Have people knock their own blocks
The easiest way to do door-knocking is to try your local area first. Being a neighbor creates an immediate connection with the person answering the door; after that, everything else is easy.
WHEN YOU GO OUT
When to go and what to do first
The best times to knock are usually Saturdays. On other days, after dinner is ideal. When someone answers the door, smile and introduce yourself. Give the name of your organization and, briefly, the reason for the visit.
State what action the other person should take and the benefits
Tell the person what they need to do and how their actions will benefit themselves and others.
Record contact information on the spot
Record names, addresses, email addresses, phone numbers, and responses to questions on the spot. You won't remember them later!
21. Why does the author say that door-knocking has become a lost art？
A. It is not effective, no one will take this method any more.
B. People focus on privacy increasingly, so door-knocking seems like an intrusion into other people's lives.
C. It is very difficult to do door-knocking, no one knows how to do it now.
22. Which step should be firstly taken when you try door-knocking？
A. Have people knock their own blocks.
B. Wear an official name tag.
C. Leave a door hanger.
23. Which time is not appropriate for door knocking？
A. Saturday afternoon.
B. Monday morning.
C. Thursday evening.
24. Who will receive pleasant reception when they try door-knocking？
A. A stranger who is not living in this community and gives no notice for his/her visit.
B. An offensive acquaintance who comes at any time.
C. A neighbor who does good preparation and has significant project to introduce.
25. What does the underlined phrase “on the spot” mean？
A. without delay.
B. at some place.
C. in a difficult situation.
Here is what Professor Wellman means. Before the invention of the Internet and e-mail, our social networks involved live interactions with relatives, neighbors, and colleagues at work. Some of the interaction was by phone, but it was still voice to voice, person to person, in real time.
A recent research study by the Pew Internet and American Life Project showed that for a lot of people, electronic interaction through the computer has replaced this person-to-person interaction. However, a lot of people interviewed for the Pew study say that's a good thing. Why？
In the past, many people were worried that the Internet isolated us and caused us to spend too much time in the imaginary world of the computer. But the Pew study discovered that the opposite is true. The Internet connects us with more real people than expected helpful people who can give advice on careers, medical problems, raising children, and choosing a school or college. About 60 million Americans told Pew that the Internet plays an important role in helping them make major life decisions.
Thanks to the computer, "networked individuals" are able to be alone and together with other people—at the same time .
The Pew study was conducted in______.
A．The United States
B．Canada
C．The U. S. and Canada
D．Europe
A.Enthusiastic and optimistic
B.A pleasure-seeker
C.Lacking in self-confidence
D.A person whose poverty stifles his ambition
How would you describe Sequoyah？ ()
A．Determined.
B．Mad.
C．Backward.
D．Meek (温顺的).
Door-Knocking
Door-knocking is the most effective way of making face-to-face community contact, but it has become a lost art.

But those who try it for the first time are usually surprised by the pleasant reception they receive. Here are some suggestions that will help you promote your services face-toface.
BEFORE YOU GO OUT
◆ Begin with a door hanger
Try leaving a door hanger two days before you go door-knocking. It should briefly describe the project and say that someone will be around in person.
◆ Wear an official name tag
Door-knockers should wear name tags with the logo of their organization. The best name tags will also include a color photo and the name of the caller.
◆ Have people knock their own blocks
The easiest way to do door-knocking is to try your local area first. Being a neighbor creates an immediate connection with the person answering the door; after that, everything else is easy.
◆ Find a good excuse to door-knock
A short survey about local concerns or a current project is a good excuse. Figure out responses for various situations. What if the person who answers the door cannot speak English? What if a child answers the door?
WHEN YOU GO OUT
◆ When to go and what to do first
The best times to knock are usually Saturdays. On other days, after dinner is ideal. When someone answers the door, smile and introduce yourself; say you are a volunteer and, if it helps, state where you live. Give the name of your organization and, briefly, the reason for the visit.
◆ State what action the other person should take and the benefits
Tell the person what they need to do and how their actions will benefit themselves and others. If a person hesitates, emphasize benefits you' ve already mentioned and then, if necessary, add further benefits. If a person agrees, follow up immediately. If possible, get a donation,a signature, or a promise.
◆ Record contact information on the spot
Record names, addresses, e-mail addresses, phone numbers, and responses to questions on the spot. You won' t remember them later!
