一、教学重点： 1. 复习一般过去时和过去进行时及区别。 2. 反身代词的用法。 3. 频度副词在一般现在时中的应用。 4. 重点词组解析。 二、具体内容 （一）一般过去时和过去进行时的区别： 1. 一般过去时常表示在过去某时发生的动作或存在的状态（包括过去的习惯动作），常与一般过去时连用的时间状语有：just now, a moment ago, yesterday, last week/month/year, the day before yesterday 及表示过去的时间状语从句。 e.g. I met her in the street the day before yesterday. Ex. Hangzhou is a nice city. My dad ????me there when I was about ten years old. A. pulled??? B. caught??? C. took??? D. brought 2. 过去进行时常用的时间状语有：at that time/moment, at this time yesterday, at +点钟+yesterday, 时间状语从句。 e.g. What were you doing at seven yesterday? Ex. I ??????on the computer when Jim came to see me yesterday evening. A. draw??? B. drew???? C. was drawing??? D. am drawing 3. 一般过去时往往表示某一动作已经发生，而过去进行时却表示动作在持续。 e.g. She wrote a letter to her friend last night. She was writing a letter to her friend at nine last night. Ex. –Why didn’t you give me a phone call? -- I ?????. But nobody answered the phone. A. do??? B. did??? C. will?? D. have 注意：下面几种情况不用一般过去时而要用过去时： 1）表示过去某一阶段的经常性动作。 Tom was studying in Paris last term. 2）与always连用表示赞美，厌烦等感情色彩时。 e.g. John was always coming to school late. 3）用来描写故事发生的情景。 It was a dark night. The wind was blowing hard and the rain was falling heavily. A young man suddenly appeared on the riverbank. He wanted to cross the river. 4）when 作并列连词，表示“这时（突然）”之意时，第一个并列分句用过去进行时，when引导的并列分句用一般过去时。 I was taking a walk when I met him. 5）go, come, leave, start, arrive 等动词可用过去进行时表示过去将来的含义。 I was leaving for Wuhan that day. Ex. （1）It was warm, so I ??????(take) off my coat. ?（2）John ???????(take) a photograph of me while I ???????(read). ?（3）Jane ??????(wait) for me when I ??????（arrive）. ?（4）Sue wasn’t hungry, so she ????????(not eat) anything. ?（5）It was hard work to carry the bags. They ???????(be) very heavy. （6）When I was young, I ???????(want) to be a bus driver. （二）频度副词在一般现在时中的应用。 表示动作发生的频率程度的副词叫做频度副词，如seldom, always, often, sometimes等。一般常用在一般现在时中，放在be动词，情态动词及第一个助动词之后，实义动词之前。 e.g He is seldom ill. ??? You must always remember this. ??? Do yo
