教学过程
教学过程 Step 1: Leading in 1. Show students the picture of tsunami and introduce the topic of this lesson: Life is full of the unexpected. 2. Lead students to say these phrases about unexpected events: flood, earthquake, typhoon, sandstorm, snowstorm, mudslide, tsunami. 3. Ask some students to talk freely about the unexpected events. Teachers can give an example, and then let them talk about the things they met in the past. Step 2: Preparation 1. Introduce the background knowledge of 911 terrorist attacks and the earthquake in Christchurch, New Zealand to students. 2. Show students the real situation of two major international events through pictures and videos. Step 3: Reading 1. Ask students to read the passage and find the following key clues (where,when,what). 2. Divide students into groups of four. Give students some time, ask them to make a summary of the passage by drawing a mind map. 3. When students have finished their own mind maps, pick some students to draw their mind maps on the board. 4. Ask students a question: “What can we learn from the passage ” Students can discuss with their partners and then give their own reflections. Step 4: Pair work Work in pairs, and ask students to retell one of the events to his / her partner. Tell students that they can use the words in the box of 3c to help them. Step 5: Language points 1. be about to be about to do意为“正要做；即将做”，侧重于表示动作马上就要发生，常与when引导的从句连用，但不与具体的时间状语连用。 One of my friends is about to have her second baby. 我的一个朋友马上就要生第二个小孩了。 2. even though even though “即使，虽然，尽管”，用于引导让步状语从句。 He’s the best teacher, even though he has the least experience. 他虽然经验最少，却是最好的老师。 3. stare stare “盯着看，凝视”表示看得比较仔细，有时候也带有吃惊的意味去看，常与at, into连用。 Don’t stare at me like that. 别那样盯着我看。 4. in disbelief in disbelief “不相信，疑惑，怀疑”。 Tamara stared at him in disbelief, shaking her head. 塔玛拉一边狐疑地盯着他看，一边摇着头。 5. above (1)表示位置“在……正上方；高于”，与 below相对。 That big high-rise above us is where Brian lives. 我们上面的那座摩天大楼就是布赖恩住的地方。 (2)表示在地位、级别、能力、资历、重要性等方面“超过”、“在……之上”、“比……强”。 He is above the others in ability. 他的能力优于其他人。 6. burn 动词burn意为“着火，燃烧”，(burnt, burnt / burned, burned)，burning是形容词，意为“着火的；燃烧的”。 Ouch! The sand is so hot! I can burn my feet. 哎哟！沙子这么烫！会烫伤脚的。 He was trapped in a burning house. 他被困在正在燃烧的房屋里。 7. alive alive 一般作表语，也可以作后置定语或宾补，表示“活(着)的；在世的；(继续)存在的”，反义词是dead。 Do you know she’s alive 你知道她还活着吗？ People alive should try their best to live better. 活下来的人应该尽力生活得更好。 辨析：alive, living和lively ①alive “活着的”，在句中常作表语或定语。作表语时，常可与living互换；作定语时，常要放在被修饰词之后。 ②living“活着的”，在句中用作表语或定语。 ③lively“活泼的”，在句中可作表语或定语。 8. take off take off 意为“脱掉；起飞”。 He took off his hat and bowed as he passed. 他经过时脱帽鞠躬。 We eventually took off at 11 o’clock and arrived in Venice at 1:30. 我们终于在11点起飞，1:30 到达威尼斯。 Step 6: Grammar points 过去完成时用法 1. 构成：由“助动词had (用于各种人称和数) + 过去分词”构成 否定式：had not + 过去分词 缩写形式：hadn’t + 过去分词 2. 用法：过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作。 3. 它所表示动作发生的时间是“过去的过去”。 (1)表示过去某一时间可用by, before 等构成的短语来表示。 (2)也可以用when, before 等引导的时间状语从句来表示。 (3)还可以通过状语从句或通过上下文暗示。 When I got there, you had already eaten your meal. 当我到达那里时，你已经开始吃了。 By the time he got here, the bus had left. 在他到达那里之前，汽车已经离开了。 Step 7: Practice 1. Work on 4a. Ask students to make sentences using by the time or before. Students make full sentences on their own, the teacher reminds them of the tenses.
