"be qualified for" 是一个常用的系表结构短语,意为:有资格做……;胜任……;符合……的条件。
其中,"qualified" 是形容词(由动词 "qualify" 派生而来),表示“具备必要条件/能力的;合格的”;"for" 是介词,引出“资格/胜任的对象”(通常是名词或代词)。
主语(通常是人) + be 动词(根据时态/人称变化) + qualified + for + 名词/代词(资格的对象)
工作/职位:表示“胜任某份工作/职位”
She is qualified for the manager position.(她胜任经理职位。)
Are you qualified for this teaching job?(你有资格做这份教学工作吗?)
机会/福利:表示“符合某机会/福利的条件”
Only students with high grades are qualified for the scholarship.(只有成绩优异的学生才有资格获得奖学金。)
He is not qualified for the loan because of his bad credit.(他因为信用不好,没有资格申请贷款。)
membership/role:表示“有资格成为某成员/扮演某角色”
You need two years of experience to be qualified for membership in this club.(你需要两年经验才有资格加入这个俱乐部。)
Is the actor qualified for the lead role?(这位演员胜任主角吗?)
两者都表示“有资格”,但后接成分不同:
"be qualified for" 后接名词/代词(资格的“对象”);
"be qualified to do" 后接动词不定式(资格的“动作”)。
例:
She is qualified for the job.(她胜任这份工作。)→ 后接名词 "the job"
She is qualified to do the job.(她有资格做这份工作。)→ 后接不定式 "to do the job"
否定:在 be 动词后加 "not" → He is not qualified for the promotion.(他没有资格晋升。)
疑问:将 be 动词提前 → Is she qualified for the internship?(她有资格做这个实习吗?)
过去时:用 "was/were" → They were qualified for the project last year.(他们去年有资格参与这个项目。)
总结:"be qualified for" 是描述“人具备某事物的资格/能力”的常用表达,重点是通过介词 "for" 连接“资格的对象”,搭配名词使用。
