It was Monday, Mrs. Smith's dog was hungry, but there was not any meat in the house.
Considering that there was no better way, Mrs. Smith took a piece of paper, and wrote the following words on it, "Give my dog half a pound of meat." Then she gave the paper to her dog and said gently, "Take this to the butcher (卖肉者) , and he's going to give you your lunch today."
Holding the piece of paper in its mouth, the dog ran to the butcher's shop. It gave the paper to the butcher. The butcher read it carefully, recognized that it was really the lady's handwriting and presently did as he was asked to. The dog was very happy, and ate the meat up immediately.
At midday (正午), the dog came to the shop again. It gave the butcher a piece of paper again. After reading it, he gave it half a pound of meat once more.
The next day, the dog came again exactly at midday. And as usual it brought a piece of paper in. the mouth. This time, the butcher did not take a look at the paper, and gave the dog its meat, for he had regarded the dog as one of his customers.

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!

The marvel of the machine age, the electronic computer has been in use only since 1946. It can do simple computations—add, subtract, multiply, and divide—with lightning speed and perfect accuracy. It can multiply two 10-digit numbers in 1/1, 000 second, a problem that would take an average person five minutes to do with pencil and paper. Some computers can work 500, 000 times faster than any person can.
Once it is given a program, that is, a carefully worked-out set of instructions devised by a technician trained in computer language, a computer can gather a wide range of information for many purposes. For the scientist it can get information from outer space or from the depths of the ocean. In business and industry the computer prepares factory inventories, keeps track of sales trends and production needs, mails dividend checks, and makes out company payrolls. It can keep bank accounts up to date and make out electric bills. If you are planning a trip by plane, the computer will find out what route to take and what space is available.
Why does the author regard the electronic computer as the marvel of the machine age？
A．Because electronic computers are rare.
B．Because people know little about electronic computers.
C．Because electronic computers can do much more kinds of work that human beings can't.
D．Because electronic computers have been widely suspected.
