反義詞

文法句型

hydrate + substance (cement, compound)

substance + hydrates (intransitive)

用法筆記

Distinguish from sense 1 (RESTORE FLUIDS): sense 1 deals with living things (body, skin); sense 2 deals with chemical substances (cement, minerals, compounds). Often appears in academic writing or technical manuals. In transitive use the subject is usually a person or a process; in intransitive use the subject is the substance itself.

常見錯誤

❌The cement is hydrating your skin.
✅The cement is hydrating as it sets.
💡Do not mix the chemistry sense with the body-care sense; 'hydrating' with people/animals belongs to sense 1.
