插入法指把难以处理的句子成分用破折号、括号或前后逗号插入译句中。这种方法主要用于笔译中。偶尔也用于口译中，即用同位语、插入语或定语从句来处理一些解释性成分。

如： 如果说宣布收回香港就会像夫人说的"带来灾难性的影响"，那我们要勇敢地面对这个灾难，做出决策。

If the announcement of the recovery of Hong Kong would bring about, as Madam put it, "disastrous effects," we will face that disaster squarelyand make a new policy decision.
