RO是PTE阅读考试中比较关键的部分，考试难度虽然不大，但是考试时间有限，因此我们需要在最短的时间拿到RO满分。下面PTE在线学院小编就为大家介绍介绍。

　　首段作为一个4段或5段短篇幅文章的开头，要么提出一个明确话题来方便读者理解，要么以一个背景故事来做铺垫抛砖引玉。也就是说首段不会去讨论或是解释细节，因为这样的首段意图不明确。

　　例题解析：

　　(A) It was a time when managers had to take a critical look at every aspect of their production process and make improvements where necessary.

　　(B) As a result, some people believe it is now time to re-assess many companies in terms of the standards they agreed to some years ago.

　　(C) In the late 1900s. food manufacturers were challenged by the organic community to ensure they were using ingredients that had been produced in natural healthy ways.

　　(D) Whether these systems have been maintained seems questionable, particularly as contracts depend so heavily on efficiency and quick sales.

　　(E) Over the last half-century, organic farming has become a driving force in the world's food market.

　　A段在强调一段时期(it was a time)。但是并没有给出一个明确的话题，容易让读者摸不清头绪。而且文中提到的managers 也没说清楚是哪来的。

　　B段在讨论结果是什么(as a result)。而且从内容的表达方式来看，some people believe… 这是在表达观点，换句话说，这就是在解释细节。

　　C段讲述了食品生产商遇到了什么挑战来确保什么。不难理解，这也是在解释细节!

　　D段these systems 是代指某部分，绝不可能出现在首段!

　　E段提出了organic farming 这个话题。所以这题不难发现E是首段。

　　除了分析每个paragraph内容，还有些一般情况下能很容易分析出不是首段的字眼,比如刚才例文里出现的代指部分(these systems)

　　1.代指部分：this xxx, that xxx, these xxx, those xxx, it, they etc.

　　2.特指名词：带定冠词the的名词用来特指之前出现的部分

　　3.逻辑关系词：because (it is due to), as a result (consequently), moreover, furthermore, additionally (in addition), subsequently, but (however), by contrast, alternatively, instead 等等.

　　总结：

　　分析内容、找关键字眼，结合以上两点分析首段，RO测试的正确率会提高很多，大家在平时的练习中可以多多运用。当然，想提高PTE成绩除了做好RO，其他部分也要加强训练。欢迎添加我们的微信：kewo-pte进行交流学习，我们为大家准备了PTE课程礼包，方便大家科学备考PTE。
