(=He opened the drawer and took ‎ out his wallet.)他打开抽屉,拿出钱包。‎ Coming into the room,he put down his bag. (=he came into the room and put ‎ down his bag.)他走进房间,放下提包。‎ Having brushed his teeth,Mr. Brown came downstairs for breakfast.‎ 布朗先生刷过牙,就下楼来吃早饭。 (此句如写成:Brushing his teeth, ‎ Mr. Brown came downstairs for breakfast.可能指“边刷牙,边下楼’。‎ ‎④分词的否定形式是在分词短语前面加上 not, never等否定词构成。‎ 例如: Not fearing the fire, the child touched and got a finger burnt. ‎ 小孩儿不知道怕火,用手去摸,把手指烫了。 Not knowing how to find the subway, I asked a policeman for help. 我不知道怎 ‎ 样找到地铁,就去找警察帮忙。 ‎ Period4Listening , Speaking and Writing Teaching goals Enable the students to listen for details and catch the specific information as much as possible.‎ Learning ability goals ‎ Enable the students to predict some important information in the process of listening and encourage the students to talk about the situations according to the listening materials. ‎ Teaching important and difficult points How to make sure the answers of listening material and help them to describe the disaster they have experienced. ‎ Teaching aids A recorder and cassette tapes, a projector, and a computer ‎ Teaching procedures ‎ Step 1 Pre-listening Can you imagine the volcanologists’ work?‎ They often face the dangerous situation.‎ Can you guess what the following three volcanologists’ most frightening experiences are?‎ Step 2 Listening Look at the pictures of volcanologists at work on page 38.

Spend a few minutes on your own imagining your experiences and how you felt. Now imagine you are safely back home. Write a dairy entry about your experience.‎ A possible version:‎ Jane and I had been waking in the mountains when we noticed some dark clouds coming down the mountain. We decided to turn around and go home.‎ ‎ As we walked the clouds got nearer and nearer and the day grew darker. Then all of a sudden it began to snow. It was soon snowing so hard we couldn’t see very far in front of us. Holding each others’ hands so we couldn’t get separated, we continued down the mountain. Butthe snow got deeper and deeper. Walking became harder and harder. We began to get very tired and very frightened.‎ After a while the path became buried under the snow and we didn’t know which way to go. We were completely lost. We found some shelter behind a big rock. Hugging each other for warmth, we stayed like that until the storm was over. Luckily it only lasted an hour or two. Then the sun came out again and we could see our house in the distance. We were so relieved we both burst into tears.‎ Step 5 Homework ‎ Finish your writing.‎
