第三章 篇章写作
第一节 如何写好开头段
SAT作文的开头段是针对材料文本写成的分析性开头段，主要由三个部分组成：主旨句、意图句和发展句。
示例一
In response to our world's growing reliance on artificial light,（意图句）writer Paul Bogard argues that natural darkness should be preserved in his article "Let There be dark".（主旨句）He effectively builds his argument by using a personal anecdote, allusions to art and history, and rhetorical questions.（发展句）
示例二
In the article "Why Literature Matters" by Dana Gioia, Gioia makes an argument claiming that the levels of interest young Americans have shown in art in recent years have declined and that this trend is a severe problem with broad consequences.（主旨句）Strategies Gioia employs to support his argument include citation of compelling polls, reports made by prominent organizations that have issued studies, and a quotation from a prominent author.（发展句）Gioia's overall purpose in writing this article appears to be to draw attention towards shortcomings in American participation in the arts. His primary audience would be the American public in general with a significant focus on millennials.（意图句）
下面我们看一下如何从这三个部分入手，写出一个漂亮的开头段。
