Call in 的句型结构
理解如何用 Call in 来造句，对于正确运用该短语动词至关重要。它既可以作及物动词（需要宾语），也可以作不及物动词（不需要宾语）。此外，其小品词 "in" 有时可以被宾语分开。下面我们详细解析 Call in 主要含义的常见句型。
"Call in" 的含义1：打电话到某地（如上班、节目）
Call in 最常用的一种情况是打电话，尤其是向单位请假或参与广播、电视节目。这种用法强调通过电话远程通报信息或参与互动。
结构1.1（不及物，常接形容词）： 主语 + call + in +（形容词如 'sick', 'well', 'late'）
- 员工需向雇主说明情况时，这一用法非常常见。短语 "call in sick" 是英文惯用语。如果你康复归来，也可以用 call in well。如果预计迟到，可用 call in late。
- Example 1: "Sarah felt a fever coming on, so she had to call in sick to her manager first thing in the morning."
- Example 2: "Many fans call in to sports radio shows to discuss the game's outcome and share their excitement."
结构1.2（暗示目的地或参与广播）： 主语 + call + in + (to + 地点/节目)
- 虽然可以说 "call the office"，用 "call in" 常强调你是从外部报告或打入中心系统或节目。
- Example 1: "Listeners were encouraged to call in with their song requests during the evening show."
- Example 2: "He had to call in to the conference line for the remote team meeting."
"Call in" 的含义2：召唤或请求帮助
Call in 的另一个重要含义是请求某人（通常是专业人士、专家或权威）到场，提供帮助、意见或处理具体情况。这通常暗示现有人手无法处理，需要外部协助。
结构2.1（及物动词，不可分割小品词）： 主语 + call + in + 某人（如专家、医生、警察）
- 这里 "in" 作为副词小品词直接修饰 "call"，被召唤的人紧随其后。
- Example 1: "The museum decided to call in an art historian to authenticate the newly discovered painting."
- Example 2: "If the situation escalates, we will have to call in security personnel."
结构2.2（及物动词，小品词可分割）： 主语 + call + 某人 + in
- 此结构非常常见，被召唤的人处在 "call" 和 "in" 之间，使句子更自然。
- Example 1: "The family had to call a plumber in when they discovered a major leak in the bathroom."
- Example 2: "The lead investigator decided to call all available detectives in to work on the high-profile case."
- 此用法表示请求帮助，通常带有重要性与正式感，指明寻求专业协助。
"Call in" 的含义3：要求归还某物
Call in 也可表示正式要求某物归还。此用法常见于财务领域，如贷款，或制造业中因质量或安全问题发起产品召回。
结构3.1（及物动词，不可分割小品词）： 主语 + call + in + 某物（如贷款、产品、报销、报告）
- 宾语为被召回或被要求归还的物品或事项。
- Example 1: "The automotive company was forced to call in over 50,000 vehicles due to a faulty braking system."
- Example 2: "Our manager will call in all outstanding expense reports by the end of the week."

- 与以上用法类似，宾语也可以置于 "call" 和 "in" 之间。
- Example 1: "The bank reserves the right to call a loan in if the borrower violates the terms of the agreement."
- Example 2: "After years of helping her, he finally decided it was time to call that big favor in."
