often 后面通常接动词或动词短语，例如 often read、often study、often drink tea。句子里有 be 动词时，often 后面常接形容词、名词或地点状语，例如 is often busy、is often happy、is often at home。遇到 will、can、should 这类助动词或情态动词时，often 常放在它们后面，再衔接主要动作，例如 will often visit、can often help。这个用法的重点是 often 作为频率副词，直接给动作、状态或情况加上“经常、常见”的语感。按“动词、be 动词、助动词或情态动词”这几类来看，often 后面常见搭配非常清楚。
【核心搭配】
- often + 动词：表示经常做某事，如 often run、often write、often learn。
- often + 形容词：多出现在 be 动词后，如 is often happy、is often helpful。
- often + 名词或表语：如 is often a reader、is often a guest。
- often + 地点状语：如 is often at the library、was often at home。
- often + 主要动词：在 will、can 这类词后，表示“会经常做某事”，如 will often stay、can often support。
【判断顺序】
- 看主语后面有没有 be 动词。有 be 动词时，often 常放在 be 动词后，后面接形容词、名词或地点。
- 看句子里有没有 will、can、should 等助动词或情态动词。有这些词时，often 放在它们后，再跟主要动词。
- 看句子里只有普通动词时，often 放在动词前，直接跟动词或动词短语。
