I thought the thief must be in the house, so I pushed the door and went into the house. The thief was looking for valuable things. When he saw me, he got a big surprise. I laughed to him, “ I cant find any money in the day, and can you find it at night?” Warm-up twoA sceneTeacher stepped into the classroom unsmilingly and said to students, “ The White House was robbed last night, and the present owner of The White House, Bush lost some priceless diamonds. He was shocked and I was designated as a detective to investigate the robbery. “Now, all of you answer my question. What were you doing at 11 oclock last night ?”Students answer: “ I was sleeping in bed at 11 last night.”“I was killing my wife sir, I didnt do any evil things.”“I was stealing some tresure from a museum, and I didnt go to America at all.”.Then teachers write down some of the sentences on the blackboard and begin to teach the key point, Past continuous tense.Warm-up threeAnswer the questions below: 1.

In that case, lets study when we grow old. Well, Im only joking. Everyone knows youth is the most precious time. So you should chrish your time.so we should translate it as:活到老，学到老。c. The Usage of GrammarA (The teacher emphasizes the past continuous tense and tells the story slowly). This is my yesterdays experience. My first sentence is “Yesterday, when I was stepping on the floor, I found my door open.” This is a background of the story. We use a new tense_ past continuous tense.Present Continuous Tense. Be doing am is arePast Continuous Tense was doing were Example:He was cooking.I was crying.They were laughing.We were playing.B We use past continuous tense to offer a background of the story.2While+时间状语从句，主句如果用while引导时间状语从句，表示主句动作发生在从句动作开始之后，从句动作比主句动作进行时间更长。所以要求从句动作用延续性动词，并常用进行时态，除非从句表述的是一种持续的状态。从句可放前可放后。While I was waiting for the train, I met my old friend by accident.Strike while the iron is hot.趁热打铁。While she was listening to the radio, she heard the bad news and cried.While the Prime minister was in china, he visited the Imperial Palace.用while引导的时间状语从句也可以表主句和从句动作同时发生，这时一般主句和从句都用进行时态，且从句放后。I was watching him while he was watching another girl.oh man! I am so jealous.我在看着他，他在看着另一个女孩。天哪！我太嫉妒了。While Newton was thinking, an appple fell on his head.3To ones surprise,+句子To ones surprise,+句子表“让。吃惊的是”， 属注评性状语， 是修饰整个句子的，一定要放句首。还可用其他表情绪的抽象名词来替换surprise, 如disappointment, satisfaction, shock, amazement, astonishment,astoundment, p;easure等。To my big surprise, he has been waiting for me for a whole night.To everyones disappointment, Jackys performance was a failure.To the teachers satisfaction, he corrected the mistake at once.To my astoundment, the beauty pageant has been cancelled.特别提示：注评性状语修饰整个句子，除了这类介词短语To ones surprise外，还有：分词：generally speaking, frankly speaking副词：fortunately不定式：to be honest, to make matter worse, to sum up总的来说。B Exercise:There are several stories. Could you give the background of the stories in past continuous tense?Example:The plane late and detectives were waiting at the airport all morning.They were expecting a valuable parcel of diamond from South Africa. A few hours earlier, someone had told the police that thieves would try to steal the diamonds.1. The whole room was empty. I was very happy because I could live in the new house at last. Although it was very shabby, it was my own.2. I returned my house, and I was so tired that I fell asleep soon. When I waked, I found my wife disappeared and there was no food and hot water. I was got so angry.3. They found a big lake at last. They ran to there and drank the water in the lake. Then they had a bath. The water was very cool and clear. They felt terribly comfortable.4. Suddenly, a big bear appeared (出现) in the rain. The workers were so afraid that they ran away at once. Only one man stood there. He was a beast trainer.We use past continuous tense in the complex sentences to offer a background of the action.While he was washing head, the dog stole the pork. (“While he was washing head,” offers the background of “stole the pork”)While he was washing head, the dog was stealing the pork.(“While he was washing head.” offers the background of “was stealing the pork”)As I were looking for diamond, the policeman arrived.As I looked for diamond, the policeman arrived.Whats difference between the two sentences?When I got off the plane, you were waving to me.When the plane was flying, it ran out of petrol. When he died, the day was broken. Exercise:Answer the questions completely.What were you doing when I taught English?What were you doing while your mother was cooking?What was the thief doing while you were sleeping?What was your father doing when you watched TV?What were you doing while you mother was sleeping?C Could you find the rules of the usage of the tenses in the complex sentences?While (past continuous tense) (past continuous tense/ past tense)As (past continuous tense/past tense) (past tense)“When” can take place of “while” and “as”, but if a whole sentence uses the past continuous, we cant use “when” instead of the two words.Exercise Put “while” “when” “as” into the blanks.1)_ he was counting money(数钱), his wife came in.2)_ they were drinking the beer, they were talking about the girls.3)_ Mr. Zhang felt excited, when he heard the news.4)_ Lili jumped off the car, the driver was telephoning his friend.5)_ the guy was looking for his homework, the teacher stopped him.6)_ the cat was running after the mouse, the dog was running after the cat.d.
