本单元围绕“Noises in the night”这一话题，辅之对话和句型，重点讲述过去分词的两种用法，即过去分词作定语和状语。本单元同时复习了拜访、互相介绍、告别场合的交际用语。掌握句型：It’s time＋主语＋动词的过去式/should＋动词原形＋sth.。 “是某人该做某事的时候了”。句型中的动词过去式并不表示过去时间的动词，而是表示虚拟语气，注意should在此处不可省。例如：It’s time you went to bed. = It’s time you should go to bed. = It’s time for you to go to bed. It’s time we started. = It’s time we should start. = It’s time for us to start. 同时，也要掌握句型： Her uncleseemed to be acting rather strangely towards her. = It seemed that her uncle was acting rather strangely towards her. 例如：My parents seemed to know that. = It seemed that my parents knew that. 通过本单元的学习，让学生对英国作家柯南道尔爵士笔下塑造的大侦探福尔摩斯在探案方面的足智多谋有进一步的了解。学习他善于观察、分析、勤于思考，严密的逻辑思维能力。培养学生遇事仔细观察、勤于思考、善于推理的能力。

The Past Participle as Attribute and Adverbial（过去分词作定语和状语）
掌握过去分词的要点是：
（1）形式：done
注意是否重复最后一个辅音字母。如：wrapped， referred to ， preferred， controlled注意是否为不规则动词。如：cut， woken， lit/lighted， burned/burnt， set， hung/hanged
（2）表示被动完成或完成
及物动词的过去分词表示被动完成。如：
the broken glasses被打碎的眼镜the teach building built last year去年建成的教学楼不及物动词的过去分词表示完成，不表示被动。如：fallen leaves 落叶the risen sun 升起的太阳retired workers 退休工人
（3）注意位置
单个的过去分词一般放在被修饰词的前面，如：the developed countries 发达国家returned students 归国留学生过去分词词组一般放在被修饰词的后面。如：the rope fastened to the tree 系在树上的绳子the trees cut down yesterday 昨天砍的树
（4）作用
