外研版初三下册Module 3 Now and then 教案

你在做听力或阅读前，你需要先仔细读读提示或说明。当你做听力或阅读时，一个很好的方法是把你的注意力锁定在你需要的信息，而不是尝试去理解每个词。

Step Ⅳ Writing.

In this procedure, get the students learn some writing skills about an argument. Pre-writing:

T: Read the passage in Activity 2 and the conversation in Unit 1, Activity 3. You’re going to write a composition. The title is:

Is life today better or worse than it was 50 years ago?

T: Before you write it, you must write down main points for the composition. For example:

Main point: People are healthier and live longer.

You also need to write down an example of each main point such as: Example: Mrs. Li says we live longer toady.

Then you can write down an opposite point to each main point and give an example of each opposite point.

For example: Opposite point: Pollution makes people less healthy. Example: Mrs. Li walks less and takes the bus more.

Students can work in pairs, groups to discuss. Try to get more main points and more opposite points. Give each point an example.

T: After getting so many points and the examples. Let’s join them together with “For example”.

People are healthier and live longer. For example, Mrs. Li says we live longer today.

Now join the main points and their opposite points with “However” or “On the other hand”.

People are healthier and live longer. For example, Mrs. Li says we live longer today. However, pollution makes people less healthy. For example, Mrs. Li walks less and takes the bus more. Writing:

T: Now you can begin your composition with the title. Next, add your main points, examples and opposite points. At last, you can finish the composition with your conclusion or opinion like this: In conclusion, I think life today is …. The sample composition:

Is life today better or worse than it was 50 years ago?

Generally speaking, the life today is better than it was 50 years ago. But on the other hand, it has its disadvantages.

Parents are less tired to support the family and educate their child. For example, today most people only have one child. However, their children are more tired. For example, two children have to look after four old people in the future.

People are healthier and live longer today. For example, Mrs. Li says we live longer. However, pollution makes people less healthy. For example, Mrs. Li walks less and takes the bus more.

It’s more convenient now. For example, there is so much more traffic and the traffic is faster. However, there is more pollution. For example, faster transport makes more pollution.

Today people’s life is more colorful. For example, they can take part in all kinds of parties and watch more programs. However, it influences the work. For example, they spend too much time on TV.

In conclusion, I think the life today is much better. But, at the same time we should think about some disadvantages and try our best to get rid of them.
