英語四級考試閱讀中常見的信號詞

　　1.以下詞組提示下文所涉及的重要信息：

　　The main / important point / conclusion / reason.

　　The point to note here

　　2.以下詞組提示了下文的結構框架：

　　There are three major reasons

　　3.but 和 however表示對比，常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.在文中提問可以突出問題后的答案，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 common cause of death in childhood.

　　5.有時，為了保證讀者完全理解自己的觀點，作者會在文中反復提出自己的觀點，例如：

　　Death control can be achieved autonomously. In other words, the death rate can be cut without anything else changing.

　　6.文章的結論通常是非常重要的，因此，讀者要在文中尋找提示結論的信號詞，例如：

　　Thereforethe result

　　In conclusionwe can conclude

　　One of the primary conclusions

　　7.舉例是為了幫助讀者理解某一個觀點，因此，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部分信息。

　　For example/instancelike

　　Such asthese include

　　To illustrateamong these are

　　有時，作者也會用破折號或括號來提示舉例信息，例如：

　　The developing countries are dependent on cash crops sugar, coffee, cacao, cotton.

　　Precipitating/violent/unexpected factors are those which reduce the food supply

　　在段落瀏覽時，讀者在看到信號詞后，應不斷對下文信息作出相應的判斷，例如：

　　The main reason for the reduction in the death rate in the developing world has been improved public health measures. For example, in Sri Lanka the death rate was halved over ten years by spraying the mosquitoes which carry malaria.

　　Why is it so easy to cut the death rate in this way and yet so hard to reduce the birth rate? One answer is that public health measures can be very cheap. Anti-malarial spraying is inexpensive. But this is not the important point .

　　For birth control programmes to be successful, a change in attitude is required, whereas death control can be achieved autonomously. In other words, the death rate can be cut without anything else changing.
