模式5

　　第一部分：把開頭分為兩段，第一段不直接進入要論述的問題和作者的觀點，而是通過一個引子展開，或講述一個有趣的故事、或交待一些背景知識，到了第二段才正式提出問題，因此在這種情況下考生要避免直接去第一段找主旨，而是要通過閱讀全文正確地定位主題所在段落；

　　第二部分：對提出的問題進行論述；

　　第三部分：得出結(jié)論，總結(jié)全文。

They can keep a wide range of records, including who sold what, when, and to whom.

Decisions to reorder or return goods to suppliers can then be made.

And they also identify preferred customers for promotional campaigns. Computers are relied on by manufacturers for similar reasons. Computer-analyzed marketing reports can help to decide which products to emphasize now, which to develop for the future, and which to drop. Computers keep track of goods in stock, of raw materials on hand, and even of the production process itself.
