语言视角
用母语深入讲解
Conditions often use 如果 or 要是 with 就 in the result clause; there is no subjunctive-style verb inflection.
如果你有时间，就来吧。

在所学语言中
英语条件句常用 if、unless、provided that、in case；还会配合 will、would、can 等情态动词、时态选择和从句位置。
If it rains, we will stay home.
If it rains 表示条件：在“下雨”的情况下，“we will stay home”（我们会待在家里）。
学习者常把条件句的时态直接按中文翻译，例如在真实条件里把 if 后面也用 will，或混淆真实条件和假设条件。
Same block, different coding
Both languages use this block strongly, but they signal it differently. Focus on form changes, not only meaning.
