     Get ready, China. The world is coming! Every say lots of foreigners come here as business people or

tourists. And even more people will come in 2008 for the Beijing Olympics. When they come to China, we

should do something to help them enjoy themselves and like China and the Chinese people.

     But there are some things they may not like:

     1. Traffic problems Cars park on sidewalks. Bus drivers drive so fast that they make people who are

trying to cross the street afraid.

     2. Queue jumping At the post office, or even at McDonald's, people push to the front of a line instead

of waiting.

     3. Bumping Too many people are crowed onto buses and trains. This makes people feel terrible, and it is

not safe, either.On a bus in North America, people try to make themselves smaller and they'll say "Excuse

me" or "Sorry" if they knock into someone. In China, people make themselves bigger with no "Excuse me"

or "Sorry"

4. Littering I notice this everywhere. Some people throw rubbish onto the ground even when there is a

rubbish bin (箱) right next to them. Most Chinese people are just as unhappy with these kinds of things as

[说明]

某图书管理系统的主要功能是图书管理和信息查询。对于初次借书的读者，系统自动生成读者号，并与读者基本信息(姓名、单位、地址等)一起写入读者文件。

系统的图书管理功能分为4个方面：购入新书、读者借书、读者还书以及图书注销。

(1)购入新书时需要为该书编制入库单。入库单内容包括图书分类目录号、书名、作者、价格、数量和购书日期，将这些信息写入图书目录文件并修改文件中的库存总量(表示到目前为止，购入此种图书的数量)。

(2)读者借书时须填写借书单。借书单内容包括读者号和所借图书分类目录号。系统首先检查该读者号是否有效，若无效，则拒绝借书。若有效，则进一步检查该读者已借图书是否超过最大限制数(假设每位读者能同时借阅的书不超过5本)，若已达到最大限制数，则拒绝借书；否则允许借书，同时将图书分类目录号、读者号和借阅日期等信息写入借书文件中。

(3)读者还书时须填写还书单。系统根据读者号和图书分类目录号，从借书文件中读出与该图书相关的借阅记录，标明还书日期，再写回到借书文件中，若图书逾期，则处以相应的罚款。

(4)注销图书时，须填写注销单并修改图书目录文件中的库存总量。

系统的信息查询功能主要包括读者信息查询和图书信息查询。其中读者信息查询可得到读者的基本信息以及读者借阅图书的情况；图书信息查询可得到图书基本信息和图书的借出情况。图书管理系统的顶层图如图10-21所示，图书管理系统的第0层DFD图如图10-22所示，其中，加工2的细化图如图10-23所示。
