主题 语境 人与自然——认识自然、探索自然
内容 分析 本部分通过文本的语句，帮助学生总结归纳过去完成时的用法并通过对袁隆平、孟德尔实验以及对龟的介绍，巩固语法及词汇知识。
教学 目标 1. 了解并掌握过去完成时的概念、特点及用法，并能够在真实语境中灵活运用； 2. 掌握过去完成时与一般过去时的区别。
教学 重点 引导学生进一步了解并掌握过去完成时的概念、特点及用法。
教学 难点 引导学生掌握过去完成时的用法。
教 学 过 程 Step 1: Lead-in 1. Look at the sentences from the reading passage and answer the questions. (1) In sentence (a), which action happened first, “suspected” or “evolved from a common ancestor” (2) In sentence (b), which action happened first, “refused to believe” or “evolved from lower forms of life” (3) What does the structure had done indicate 2. Now look for more sentences with the past perfect tense in the reading passage, and summarize its use in your own words. 教师引导学生观察例向并归纳总结过去完成时的特点。 Step 2: Discovering the rules Past perfect 【1】表示在过去某一时刻或某个动作之前已经发生或完成的动作或存在的状态。这个过去的时刻常用by, before, until等引导的短语或时间状语从句来表示，也可以通过一个表示过去的动作或上下文来表示。 By nine o'clock last night, we had finished most of the work. She had learnt about 500 English words before she went to middle school. 【2】表示过去某一时间之前发生的动作或存在的状态一直持续到那时，并可能继续下去，常同由for或since引导的表示一段时间的短语或从句连用。 I had been at the bus stop for 30 minutes when a bus finally came. She said she had made great progress since she came here. 【3】在含有定语从句的主从复合句中，如果主从复合句叙述的是过去的事，则先发生的动作常用过去完成时。 She returned the book that she had borrowed. The twins, who had finished their homework, were allowed to play badminton on the playground. 【4】在含有时间、条件、原因、方式等状语从句的复合句中，若主从句动作的发生有先后顺序，动作在前的要用过去完成时，动作在后的要用一般过去时。 I had finished cooking dinner before you came back. I found the lecture hard to follow because it had started when I arrived. 【5】want, hope, mean, plan, intend等动词的过去完成时可以用来表示过去未曾实现的想法、希望、打算或意图，意为“本来……”。 I had hoped to be back last night, but I didn't catch the train. We had intended to come and see you. 【6】过去完成时常用于某些固定句型： 在“hardly...when/ no sooner...than/ scarcely...when”句型中， 主句用过去完成时，从句用一般过去时。 I had no sooner reached home than it began to rain. ＝No sooner had I reached home than it began to rain. It was＋一段时间＋since从句(从句用过去完成时) 。 It was at least three months since I had left Beijing. 【7】过去完成时常用于某些固定句型： It was the first/second/...time＋(that)从句 (从句用过去完成时)。 It was the first time that I had chatted online in English. by the time＋表示过去的从句＋主句(过去完成时)。 By the time I got to the station, the train had already gone. by the end of＋表示过去的时间＋句子(过去完成时)。 By the end of last term we had learned 10 units. 【8】过去完成时用于虚拟语气中，在wish, as if/as though, if, if only, would rather sb. had done sth.结构或从句中，常用过去完成时来表示与过去事实相反的假设。 If he had caught the early bus this morning, he would not have been late for class. I would rather she hadn't done that. 教师可根据班级实际情况进行授课。 Step 3: Comparison 过去完成时与一般过去时的区别： 虽然这两种时态都表示过去发生的动作或存在的状态，但在使用时应注意以下几点： (1) 时间状语不同：过去完成时在时间上强调“过去的过去”；而一般过去时只强调过去某一特定的时间。 比较：They had arrived at the station by ten yesterday. They arrived at the station at ten yesterday. (2) 在没有明确的过去时间状语作标志时，谓语动词动作发生的时间先后须依据上下文来判断：先发生的用过去完成时，后发生的则用一般过去时。 She was very happy. Her whole family were pleased with her, too. She had just won the first in the composition competition. (3) 当两个或两个以上接连发生的动作用 and 或 but 连接时，按时间顺序，只需用一般过去时来代替过去完成时；另外，在 before ， after ， as soon as 引导的从句中，由于这些连词本身已经表示出时间的先后，因此也可以用过去时来代替过去完成时。 He entered the room, turned on the light and read an evening paper. Step 4：Practice 1. Complete the paragraphs with the information from the given sentences. 教师带领学生填空，在真实语境中巩周对动词不同时态的理解。 2. Complete the online encyclopedia entry with the correct form of the words in the box. 教师引导学生在真实、具体的语境中运用动词的不同时态。 Step 5: Summary Help the students summarize what they have learnt in this class. (1) 过去完成时主要用来表示在过去之前发生的事或做的动作，即过去的过去，通常与一般过去时连用。 (2) 结构: (3) 用于过去完成时的基本用法: Step 6: Homework Finish the relevant exercises of this class.
板 书 设 计 Past perfect： 肯定式：主语+had+动词过去分词+其他 否定式：主语+had+not+动词过去分词+其他 被动式：主语+had(not) +been+动词过去分词+其他.
