这里给大家找了2001年6月四级考试阅读理解的Passage　Four　， 把文章简单地分析了一下， 建议大家研究真题的时候从这几个角度着手。
研究真题，我们可以领会到命题者的出题思路，可以找出常考的考点，可以学会单词用法，可以学会能够在作文中用上的句型。
最近很忙，我只能利用半个小时左右的时间匆匆写下了这篇小文，有不到之处，请各位同学原谅。

擒贼先擒王，祝大家一举突破阅读，顺利攻克四六级！
Questions　26　to　30　are　based　on　the　following　passage.　
We　can　see　how　the　product　life　cycle　works　by　looking　at　the　introduction　of　instant　coffee.　When　it　was　introduced,　most　people　did　not　like　it　as　well　as　"regular"coffee　and　it　took　several　years　to　gain　general　acceptance　(introduction　stage).　At　one　point,　though,　Instant　coffee　grew　rapidly　in　popularity　and　many　brands　were　introduced　(stage　of　rapid　growth).　After　a　while　people　became　attached　to　one　brand　and　sales　leveled　off　(stage　of　maturity).　Sales　went　into　a　slight　decline　（衰退）when　freeze-dried　coffees　were　introduced　(stage　of　decline).　
第一段中有三个句型可以在图表作文中应用：
1. Instant coffee grew rapidly in popularity.
比如说The mobile phone has grown rapidly in popularity.
2. Sales leveled off.
或者也可以这样说:Sales remaind constant / steady / stable / much the same
3. Sales went into a slight decline.
或者也可以这样说: Sales declined slightly / deramtically / substantially
The　importance　of　the　product　life　cycle　to　marketers　is　this:　Different　stages　in　the　product　life　cycle　call　for　different　strategies.　The　goal　is　to　extend　product　life　so　that　sales　and　profits　do　not　decline.　One　strategy　is　called　market　modification¹.　It　means　that　marketing²　managers　look　for　new　users　and　market　sections.　Did　you　know,　for　example,　that　the　backpacks　that　so　many　students　carry　today　were　originally　designed　for　the　military?　
Market　modification　also　means　searching　for　increased　usage　among　present　customers　or　going　for　a　different　market,　such　as　senior　citizens.　A　marketer　may　re-position　the　product　to　appeal　to　new　market　sections.　
Another　product　extension　strategy　is　called　product　modification.　It　involves　changing　product　quality,　features,　or　style　to　attract　new　users　or　more　usage　from　present　users.　American　auto³　manufacturers　are　using　quality　improvement　as　one　way　to　recapture　world　markets.　Note,　also,　how　auto　manufacturers　once　changed　styles　dramatically　from　year　to　year　to　keep　demand　from　falling.　
二三两段我们又可以学到对某个概念下定义的两个句型:
It means that...
It involves ...
另外,大家要注意文章第一段为第一层,二三两段为第二层,第四段为第三层.
One 　strategy　is　called　market　modification.
Another 　product　extension　strategy　is　called　product　modification.
另外，同学还必须熟悉文章中的单词用法 和考点（比如例证考点等）
比如life cycle, general acceptance, extend one's life, 等等，
这些都是完形填空中会考到的搭配。
