易错句子What with the heavy rain, so we decided to stay at home.

正确表达What with the heavy rain, we decided to stay at home.

“what with” 本身就表示原因，主句前不能再加连词 so。汉语“因为……所以……”要求两个词成对出现，但英语一个句子只能用一个连接手段，加上 so 就变成重复连接。

易错句子What the traffic jam, I arrived late.

正确表达What with the traffic jam, I arrived late.

这个副词用法的 what 必须与 with 搭配，构成固定短语 “what with + 名词”，不能单独用 what 引导原因状语；去掉 with 后句子不合语法。

易错句子What with it rained heavily, we stayed at home.

正确表达What with it raining heavily, we stayed at home.

“what with” 后面接名词性成分；若要接小句，动词须用动名词形式（it raining），不能用限定动词过去式 rained。汉语“由于雨下得很大”是完整小句，直译会把限定动词一起搬进英语。
