Reorder算是PTE阅读里面难度较高的题型了，花费很多时间，却得不到多少分数。有时候，看reorder的答案，也并不觉得它的逻辑有多好，甚至两句话颠倒也说得通。那么今天，我们来聊聊Reorder这一部分，应该怎么做?

我们来看看河马这道题：

1）This natural process results in millions of tons of hippo dung during entering Africa’s aquatic ecosystems every year.

2）However, as distasteful as that might seem, the hippo’ deposits actually serve an important ecological function.

3）Lumbering out of the water at night, these herbivores graze ontropical grasses and consume 80 to 100 pounds in one meal.

4）By daybreak, having eaten their fill, they return to their daytime resting area to rest, digest and, eventually, eliminate.

5）A common hippopotamus can spend up to 16 hours a day immersed inrivers and lakes.

答案是：53412

虽然文章词汇较难，文本较长，但若掌握方法，可以在1min内快速选出答案的。

Step 1: 找到独立的句子

       独立的句子要满足以下几点：

·        介绍文章主题

·        句子是完整的：即便单独拿出来，读者也能读得懂

·        不需要回顾其他句子

在这篇文章中，

1）第一句，有指代词this; 

2）第二句，有转折词However;

3）第三句，有指代词these;

4）第四句，有代词they。

5）第五句，主谓宾齐全，句子完整，是独立的句子，也是本文的第一句话

        所以，前四句话均不是完整的，需要其他句子的解释。

Step 2: 注意主谓宾的指代

1）This natural process results in millions of tons of hippo dung during entering Africa’s aquatic ecosystems every year.

2）However, as distasteful as that might seem, the hippo’ deposits actually serve an important ecological function.

3）Lumbering out of the water at night, these herbivores grazeon tropical grasses and consume 80 to 100 pounds in one meal.

4）By daybreak, having eaten their fill, they return to their daytime resting area to rest, digest and, eventually,eliminate.

5）A common hippopotamus can spend up to 16 hours a day immersed in rivers and lakes.

各句的主谓宾已经标在上文：主语(下滑线)，谓语（阴影）

为什么要分析每句的主谓宾呢？

因为RO遵循这样的法则：

宾语1=主语2

宾语2=主语3

宾语3=主语4

从而形成逻辑链条

给大家举一道熟悉的鸡经题：

•    A requirement of Humanities 104 is to write a persuasivepaper on a topic of your choice.

•    The topic you choose should be supported by arange of sources

•    The source should be cited under APA guidelines,and the final draft should be written in APA styles

•    The final draft is due one week before thefinal exam.

我们可以看出，完全符合RO主谓宾法则

宾语1=主语2

宾语2=主语3

宾语3=主语4

那么河马这篇文章，我们便可以看出

·   A common hippopotamus can spend up to 16 hours a day immersed in rivers and lakes.

·   Lumbering out of the water at night, these herbivores graze on tropical grasses and consume 80 to 100 pounds in one meal.

·   By daybreak, having eaten their fill, they return to their daytime resting area to rest, digest and,eventually, eliminate.

·   This natural process results in millions of tons of hippo dung during entering Africa’s aquatic ecosystems every year.

·   However, as distasteful as that might seem, the hippo’ deposits actually serve an important ecological function.

本篇文章的难度，也在于它并非是原词指代，而是同义转换。

比如，第一句的rivers and lakes，对应第二句的water

     第二句的meal，对应第三局的having eaten their fill

     第三句的eliminate（排泄物），对应第四句的this natural process

     第四句的hippo dung，对应第五句的the hippo’ deposits

所以，即使里面有大量的生词，只要我们分析好主谓宾，抓好指代部分，也就可以快速地把题目做出来。

Step 3: 通读文章，逻辑环不中断

不要像图中一样，使得逻辑链条中断。

做RO的最后一步，就是要通读文章，使得逻辑通顺，结构完整。

大家可以用同样的方法试试其他题型：

•  Electronic transactions arehappening in closed group networks and Internet. Electronic commerce is one ofthe most important aspects of Internet to emerge.

•  To support e-commerce, we needeffective payment systems and secure communication channels and data integrity.

• The whole structure oftraditional money is built on faith and so will electronic money have to be.

•  Cash transactions offer bothprivacy and anonymity as it does not contain information that can be used toidentify the parties nor the transaction history.

•  Moreover, money is worth whatit is because we have come to accept it.

答案：45312

•  Piano keys are generally madeof spruce or basswood, for lightness.

•  Traditionally, the black keyswere made from ebony and the white keys were covered with strips of ivory, butsince ivory-yielding species are now endangered and protected by treaty,plastics are now almost exclusively used.

•  Also, ivory tends to chip moreeasily than plastic.

•  Spruce is normally used inhigh-quality pianos.
