在文章的瀏覽(即略讀，skimming)過程中，對文中信息主要性的判斷能够幫助讀者疾速有傚天懂得段降的粗心。在瀏覽過程中，讀者能够通過尋找“信號詞”來區分重要信息跟非主要信息。以以下出的是閱讀過程中常見的僟類“信號詞”。
1.以下詞組提醒下文所波及的重要信息：
The main / important point / conclusion / reason….
The point to note here…
2.以下詞組提示了下文的結搆框架：
There are three major reasons…
3.but 战 however表现對比，经常用來提示重要信息，例如：
The rising birth rate is not due to increased fertility, but to a sharp decline in the death rate.
4.在文中提問可以凸起問題後的答案，提示讀者答案中有重要信息，例如：
Why is a piped water supply so important? Disease due to contaminated water is a mon cause of death in childhood.
5.有時，為了保証讀者完整懂得本人的觀點，作者會在文中反復提出本身的觀點，例如：
Death control can be achieved autonomously. In other words, the death rate can be cut without anything else changing.
6.文章的結論凡是是十分主要的，因而，讀者要正在文中尋找提醒結論的“疑號詞”，例如：
Thereforethe result
In conclusionwe can conclude
One of the primary conclusions
7.舉例是為了幫助讀者了解某一個觀點，是以，文中的例子不是瀏覽文章時的重要信息。在閱讀過程中，以下詞組提示讀者下文是舉例局部信息。
For example/instancelike
Such asthese include
To illustrateamong these are
有時，作者也會用破合號或括號來提示舉例信息，例如：
The developing countries are dependent on cash crops 翻 sugar, coffee, cacao, cotton.
Precipitating/violent/unexpected factors are those which reduce the food supply (droughts, floods, wars, epidemics)…
在段落瀏覽時，讀者在看到信號詞後，應不斷對下文信息做出相應的判斷，例如：
The main reason for (提示：下文信息重要) the reduction in the death rate in the developing world has been improved public health measures. For example, (提示：下文信息不重要，僅僅是為了用來証明前里的觀點) in Sri Lanka the death rate was halved over ten years by spraying the mosquitoes which carry malaria.
Why (提示：問題的谜底中有讀者應該關注的重點) is it so easy to cut the death rate in this way and yet so hard to reduce the birth rate? One answer (提示：這只是眾多谜底中的一種，並不是最重要的。) is that public health measures can be very cheap. Anti-malarial spraying is inexpensive. But this is not the important point (提示：but後面的是无比重要的信息). For birth control programmes to be successful, a change in attitude is required, whereas death control can be achieved autonomously. In other words, (提示：這裏是作者念要強調的重要信息) the death rate can be cut without anything else changing.
