     The American humorist,Will Rogers,used to say," All I know is what I read in the newspapers".  This

was an exaggeration for humorous purposes,but it is true that newspapers are an important source of

information.  Many people begin their day by reading the paper. In this way they leam what is going on in

the world. Sometimes,however,they don't have time to read the news carefully and must be satisfied with

a quick look at the front page;at other times they may be in such a hurry that they have time only to glance at the headlines.

     There are newspapers to satisfy every reader. In the big cities there are many types of papers,with

several different editions every day. In small towns there are fewer newspapers and perhaps only one

edition each day. In some areas the

paper is printed weekly.

     Most newspapers have several sections,especially on Sundays when the edition is larger than usual.

There are,in addition to the front page with the most important news,the sports section,the society page,

the comics,the amusement section,a business page,and the editorials.

     Another type of publication which helps keep the population informed is the magazine. Some

magazines are published weekly,others are put out monthly. There are news magazines,literary magazines,

and magazines for such special interests as photography,sports,art,and music. Some are primarily for men,others for women,and there is a selection of children's magazines,too. In the United States,there are publications for every taste and interest.

在某些系统中，存在非常复杂的对象，可以采用循序渐进的方式进行组合，将小对象组合成复杂的大对象。
以下实例展示了Builder(生成器)模式。该实例用来建立“文件”，文件内容包括：一个标题、一串字符以及一些有项目符号的项目。Builder类规定组成文件的方法，Director类利用这个方法产生一份具体的文件。图5-1显示了各个类间的关系。
