　　Only a hundred years ago, people seldom traveled far out of their birth place. Books were very expensive and there were few national newspapers and no radio or television. In fact, most people spent their time talking and listening. Only a very small quantity of reading and writing went on and many people were unable to read or write. For this reason, native dialects(方言)grew up and people spoke the way their parents and grandparents spoke. A woman from Cornwall who traveled just as far as London would find herself in a place where people spoke what was almost a different language.

　　Sometimes it is hard to take in just how much things have changed. You are used to owning books and having them around, to reading magazines and newspapers and to a choice of national television and radio programs. You, and everyone around you, are used to traveling not just in the British Islands but all over the world. Modern science has changed our life and distances have been made shorter. It might have taken that Cornwall woman three days to travel to London. Now it takes less than two hours by air, less than four hours by train and less than six hours by road.

　　The result of this is that the language we use is becoming more national and the dialects are dying out. Writing, printing and broadcasting have speeded up this change as one dialect has come to be used by more and more people. This is the dialect called standard (标准的) English which was first used outside London in the south and east Midlands.

It is possible to do many simple tricks with numbers. Here is one trick. It has several separate steps.

 　　 First, write down your house number. For example, if your address is 73 Lemon Street, you would write down 73. After you write down your house address, next double it, then add five to this double number. For example, if your address was 73 and you doubled it, you would get146. Then, if you added five, you’d get 151.

 　　 Then multiply this number by 50. In our example here, you’ll get 7550. The next step is to add your age to this total. For example, if you’re26 years old, you should add 26 to this total. In our example here, the result would be 7576.

 　　 After that you have to add the number of days in a year, which is 365. In our example here, 365 added to 7576 is 7941.

 　　 The final step is this: Subtract 615 from the number that you have. Take away 615 from the total. In our example, 7941 minus 615 is 7326.

 　　 The result here —7326— is the trick. The first part of the number is the address and the last part of the number is the age of the person. That is, 73 is the address that we started with, and 26 is the age that we used.
