- phase out 表示「逐步淘汰、分階段停止」，強調一個舊事物或舊系統的結束與移除過程。

- 被動語態 (be phased in/out) 也很常見，用來強調事物是被逐步實施或淘汰的。

phase vs stage
「phase」強調逐步、分階段的過程或轉變，常用於計畫、專案或技術的導入。而「stage」則更側重於發展過程中的一個特定時期或步驟，常與生命週期、成長或活動相關。
phase vs gradually
「phase」作為動詞，指有計畫地、分階段地實施或改變某事物。而「gradually」是副詞，僅描述變化發生的緩慢與漸進特性，不涉及具體的階段劃分或計畫。
phase vs implement
「phase」強調以分階段、逐步的方式執行，注重過程的時間序與分段。而「implement」泛指執行、實施某項計畫、政策或系統，不特別強調是否分階段進行。

常見錯誤
What are common mistakes with "Phase"?Which "Phase" sentences look correct but are wrong?
×The loud noise didn't phase him at all.
✓The loud noise didn't faze him at all.
"phase" (verb) means to carry out in stages, while "faze" means to disturb or disconcert. These are often confused due to similar pronunciation.
×The company will phase the old system on October.
✓The company will phase out the old system in October.
The correct phrasal verbs are "phase in" (introduce gradually) and "phase out" (remove gradually). They require the correct preposition and cannot be used with a simple direct object and time expression alone.
×He is in a difficult phase of his career.
✓He is in a difficult phase of his career.
This sentence is grammatically correct when "phase" is used as a noun. The common mistake is using the verb form "phase" when the noun form is needed. The verb requires an object and an action (e.g., phase something in/out).
×The new policy phases next month.
✓The new policy will be phased in next month.
As a transitive verb meaning to implement gradually, "phase" (in the sense of phase in/out) is typically used in the passive voice when the thing being introduced or removed is the subject of the sentence.
×Last year, we phase out the old model.
✓Last year, we phased out the old model.
The verb "phase" must be conjugated for tense. In past tense narratives, the simple past "phased" is required.
