教学过程

Step 1 Lead-in

Review the passage of Stonehenge with the help of the mind-map.

Step 2 writing  

Show the students how to write a story.

发现问题(topic sentence):

Something unusual is happening in our town.

所见所闻

Every night, Victor hears strange noises outside their window. His wife thinks it could be an animal…

作出自己的推测

…but I do not think that is going to happen. The noise-maker is having too much fun creating fear in the neighborhood.

While reading, take notes or underline the main ideas in the text.

After reading, write a short summary in your own words. This will help you to understand the text better.

Work on 3a.

Read through the article in 3a on page 59 again. What do you think the noises could be? List all your ideas. See who in your group can come up with the most imaginative explanation.

Tips:

1. Use could, might, must, can’t to make your inferences and have a discussion.

2. We should think of more practical reasons rather than something mystical, for example, don’t say that ghosts were the ones making the noses.

Work on 3b.

Look at this newspaper headline and finish the article about the strange happenings.

No More Mystery in the Neighborhood

Last week, in a quiet neighborhood, something strange happened…

We now know what was happening in the neighborhood…

Now the mystery is solved. People in the neighborhood…

Writing tips:

First part: background information about the mystery

Second part: how the mystery was solved

Third part: how the people in the neighborhood now feel

Sample:

No More Mystery in the Neighborhood

    Last week, in a quiet neighborhood, something strange happened. Residents heard noises in the night but no one knew why. Victor Smith thought that it was teenagers having fun while Mrs. Smith and their neighbor, Helen Jones, blamed it on animals.

    We now know what was happening in the neighborhood. A ranger’s station（护林站）was being built in the nearby forest. Trees had to be cut down to make space for the station. This affected some animals living in the forest. A raccoon(浣熊）family lost their home and had problems finding food. The raccoons discovered food in the neighborhood’s garbage bins, so they came back every night.

Now the mystery is solved. People in the neighborhood feel sorry for the raccoons and they are trying to help them.
