八年级英语 Unit2 复习教案 牛津版教学目的1. To go over unit 2 教学重点和难点1. Grammar in this unit and some words and expressions教学过程一、重点词汇：souvenir, cute, pie, biscuit, performer, clap, march, gift, shiny, bow, wave, helpless, delight(ful), harm(ful/less), meaning, line, web, discuss, sailing, tie, clearly, trunk; 二词组短语：go on a trip, the whole day, buy sth for sb, even through, clap hands, wave to sb, dance to the music, search the World wide Web, get lost, go sailing, all year round, package tours, as well, right now; take photos;三、结构句型：I went to Hellos house as soon as we arrived. Everything there was so beautiful that I wanted to live in it. It seemed to be hopeless to try to get inside. Spring is the best time for visiting Chinese gardens. Is there anything I can do for you? The day of our trip to Japan finally arrived.四、重点语法 （一）过去进行时：past continuous tense 1、现在进行时和过去进行时这两个时态的动词在形式上都是由“be+现在分词”构成，只是过去进行时表示过去某一时刻或某一段时间正在发生的动作，国此助动词由was, were代替现在进行时中的助动词am, is, are。 2、过去进行时的构成： 只要把现在进行时中的am/is/are改成它们的进去式was/were就行了。 肯定句：主语+was/were+现在分词+. 否定句：主语+was/were+not+现在分词+. 疑问句：Was/Were+主语+现在分词+.? 3、进去进行时的用法： （1） 表示过去某一时刻正在进行的动作。这时常和at this/that time, this time yesterday, at six last Sunday等时间状语连用。如：He was watching TV this time yesterday. 昨天这个时候他正在看电视。 They were sweeping the floor at four yesterday afternoon. 昨天下午四点他们在扫地。 (2) 表示过去某一段时间内正在进行的动作。这种用法往往也有具体的时间状语，或与另一个动作相对应。常与from seven to eleven yesterday morning, the whole evening等状语或以when, while引导的时间状语连用。如： What were you doing from two to three yesterday afternoon? 昨天下午2点到3点你在干什么？ It was raining all yesterday evening. 昨天整个晚上都在下雨。 When they came in, we were doing our homework. 当他们进来时，我们正在做作业。 My father was watching TV while my mother was cooking. 我爸爸在看电视而我妈妈在做饭。 4、过去进行时与一般过去时的区别：一般过去时强调事情的结果，已经过去了；而过去进行时更强调事情进行的状态，不一定做好了。如： My mother cooked supper yesterday evening. 昨晚妈妈做了晚饭。（晚饭做好了。） My mother was cooking supper yesterday evening. 昨晚妈妈在做晚饭。（晚饭有没有做好不清楚。） （二）while和when while和when都可解释为“当的时候”，大多数时候两者可以互换。如： Kitty waved to the visitors while/when she was dancing to the music. 当凯蒂随着音乐翩翩起舞时她向来访者挥手致意。 但是while引导的从句中必须用进行时态，而when引导的从句并不一定要用进行时态。如： The teacher came while the students were talking loudly. The students were talking loudly when the teacher came in. 老师进来时学生们正在大声喧哗。 （三）sothat结构 sothat表示“如此以至”，中间应用形容词或副词的原级。如： The little girl is so beautiful that everyone wants to kiss her. 小女孩非常漂亮以至于大家都想亲亲她。 The little girl danced so beautifully that everyone screamed. 小女孩舞跳得非常漂亮以至于大家都欢呼了起来。 当sothat后跟了can/could not时，这个结构还可以和tooto结构互换。如： I was so tired that I couldnt walk on. = I was too tired to walk on. 我太累了而不能再走下去。 He walked so slowly that he couldnt catch the early bus. = He walked too slowly to catch the early bus. 他走得太慢了以至于没能赶上早班车。五、例题解析 1、误：He is so a clever boy that he can work out the maths problem. 正：He is a so clever boy that he can work out the maths problem. 解析：so修饰的是形容词，应该直接位于形容词前面。因此只能说a so clever boy，但我们可以说such a clever boy。 2、误：Tom was doing his homework while the other boys played football. 正：Tom was doing his homework while the other boys were playing football. 解析：while引导的时间状语从句中必须用进行时。 教学后记1 语法较简单，但是有几个考点必须掌握。
