She was looking forward to her holiday in Florida with her family. One day, as she was leaving the store, she noticed a parcel on the floor. It was addressed to a Mr. James at an airport hotel.” 【解析】“had been working” 是过去完成进行时，表示在过去某个时间之前一直在进行的动作；“as” 引导时间状语从句，“be addressed to” 意思是 “寄给；写给”。 索菲捡起包裹决定自行送往酒店，因她认为包裹可能装有贵重物品。到达酒店后发现收件人已退房，索菲不知所措，此时一位侦探出现询问包裹情况。 【原文】“Sophie picked up the parcel and decided to take it to the airport hotel herself. She thought it might be something valuable. When she arrived at the hotel, she asked for Mr. James at the reception. The receptionist told her that Mr. James had checked out. Sophie was disappointed. She didn't know what to do with the parcel. She was about to leave when a man came up to her and said he was a detective. He asked her about the parcel and Sophie told him the story.” 【解析】“pick up” 表示 “捡起；拾起”；“check out” 表示 “结账离开；退房”；“be about to do sth. when...” 表示 “正要做某事这时…”。 侦探打开包裹，发现里面有钻石项链及其他宝石，从而意识到包裹是从珠宝店被盗而来。他让索菲描述可能留下包裹之人，索菲记忆模糊，侦探表示会保管包裹并追查小偷，同时感谢索菲的诚实。 【原文】“The detective opened the parcel. Inside, he found a diamond necklace and some other precious stones. He realized that the parcel had been stolen from a jewelry store. He asked Sophie to describe the person who might have left the parcel in the store. Sophie said she didn't remember much. The detective then told her that he would keep the parcel and try to find the thief. He also thanked Sophie for her honesty.” 【解析】“realize” 表示 “意识到；明白”，这里包裹被盗是过去发生且对现在有影响，所以用过去完成时的被动语态 “had been stolen”。 数日后，索菲收到侦探来信，得知小偷已被抓获。小偷从多家商店盗窃包裹，并将赃物藏于机场附近沙坑。侦探强调索菲的帮助对破案极为重要，索菲听闻消息十分高兴，并为自己的正确行为感到自豪。 【原文】“A few days later, Sophie received a letter from the detective. He told her that they had caught the thief. The thief had stolen several parcels from different stores. He had hidden the stolen goods in a sandpit near the airfield. The detective said that Sophie's help had been very important in solving the case. Sophie was very happy to hear the news. She was also proud of herself for doing the right thing.” 【解析】此段继续讲述故事后续发展，“had stolen” 和 “had hidden” 是过去完成时，强调在过去某个时间（收到信之前）已经完成的动作。 三、语法点：过去完成时 【构成】“had + 动词的过去分词”。例如：I had finished my homework before I watched TV.（我在看电视之前已经完成了作业。） 【用法】 表示在过去某个时间或动作之前已经发生或完成的动作，即 “过去的过去”。在课文中，“The detective realized that the parcel had been stolen from a jewelry store.” 侦探意识到包裹被偷这个动作发生在打开包裹（过去的动作）之前，所以用过去完成时的被动语态。 常与 “by + 过去时间点”“before + 过去时间点或一般过去时的句子” 等时间状语连用。例如：By the end of last year, we had learned 2000 English words.（到去年年底，我们已经学了 2000 个英语单词。） / He had left the room before I arrived.（在我到达之前他已经离开了房间。） 在含有宾语从句的复合句中，如果主句是一般过去时，从句中表示过去的动作先于主句动作发生，从句要用过去完成时。如：She said that she had seen the movie.（她说她已经看过那部电影了。） 四、习题 用所给单词的适当形式填空 The ______ (value) necklace was stolen from the store.
