沈阳今天给大家分享大作文常见句型的写作方法。在本系列中，我们选取雅思作文中最为常见的句子句式进行写作讲解。希望同学们可以灵活多变的学习句子使用方法。

　　句子结构

　　from A it is deduced that B

　　结构来源

　　From this evidence it was deduced that there had been three major waves of migration across the Bering Strait.

　　[译] 从这些事实中我们推断：主要有三次横穿白令海峡的移民浪潮。

　　*此句出自雅思阅读文章。

　　结构解析

　　此结构可表达“从A中我们推断出B这一结论”的意思，这里A是某个名词性成分，B是一个完整的句子。在学习这个结构的时候可以联想一些类似的句型结构，例如A draw a conclusion from B: C。我们在作文中常常由一个论据推倒出某个结论，我们可以尽量变换结构表达这类意思。

　　模仿使用

　　From the report above it is deduced that a person’s job has more effect on his happiness than his social life does.

　　[译] 从上述报告中我们推断：人们的工作对幸福的影响要大于社交生活对幸福的影响。

　　适用题目举例

　　Leisure is a growing industry, but people no longer entertain themselves as much as they used to because the use of modern technology has made them less creative. Do you agree or disagree?
