在英譯漢時有時需要將整個句子的結構轉換。例如，把英語的簡單句譯成漢語的複合句，把一種從句譯成另一種從句，把並列句譯成複合句等，這主要是為了使譯文通順自然，符合漢語的習慣。
轉譯成主從複合句
1.簡單句轉譯成複合句

F. He differed from his workmates in spending his spare time reading. 他跟他的夥伴們不同，他把業餘時間用在讀書上了。
並列句轉譯成複合句：有時，英語的幾個小分句譯成漢語後就變成了一個主從復和句，例如：
a. Choosing the right career is very important. Most of us spend a great part of our lives at our jobs. For that reason we should try to find out what our talents are and how we can use them. (選則適合自己的工作是很重要的，因為工作佔據了我們一生中的大部分時間，所以，我們應儘可能認識一下自己的天賦在什麼地方以及怎麼樣發揮等。)
分詞短語還原譯成複合句：b. People exposed to bright red show an increase in heartbeat，and blood pressure; red is exciting. (如果將人暴露給紅顏色，他們就會顯露出心跳加快、血壓增高等;紅顏色讓人興奮。)
