Ⅱ.The analysis of the teaching material

The topic of this unit is “

making a difference”. In this unit, first we can learn about the science subjects and know the importance of each subject. Second, we can get familiar with some great scientists and their famous quotes and achievements, such as Stephen Hawking, Galileo, Albert Einstein, ZhangHeng and so on. Third, we will know how the discoveries and inventions of the great scientists help us better understand the world and improve our life.

By knowing this, students are encouraged to study hard, and their love of science and their hope of becoming scientists are inspired. 1. Language study

It contains word study and grammar. Students will have a better knowledge of the uses of the infinitive in this part. 2.Integrating skills

It includes reading and writing. In the reading passage, students can learn about characteristics of five scientists and their scientific spirit. In the writing part, students are asked to write a paragraph to describe a favourite scientist. 3. Tips

Unit One also gives students some advice on how to use the scientific method to learn English. 4. checkpoint

It sums up the uses of the infinitive.

Ⅲ.Teaching arrangements Notes: 1. Amending

In warming up, it’s too abstract for the students to talk about the quotes, so we deal with it as a unit task to the students at the very beginning-―make up a column about scientists and their quotes.

2. Replacement

In speaking, the text gives the students the debate: Which branch of science is more important and useful to our society? It’s too difficult and abstract for the students to carry it out. The reasons are as follows:

1) Their vocabulary is not large enough. 2) It’s too difficult to divide each branch of science in our daily life. In fact, each branch can’t be divided from the others. Only by combining them together, can we make our world more beautiful.

So we change the topic, and ask the students to talk about what has happened in our daily life. That is , should a nuclear power station be built in Sanmen? This topic can give the students lots of space to talk about.

3. Adding

This unit doesn’t give a good sample for the students to write about a scientist. So it is also very difficult for the students to do the writing well. Because of this, we add a research task to the students after finishing the reading material No Boundaries. (What is science and what is the spirit of a scientist?

Do research on your favorite scientist and try to find out what makes him /her successful. The students are asked to finish the task by surfing the Internet.) With the help of the first unit task--- to make up a column about scientists and their quotes, it’s possible for the students to write a good article about a favorite

scientist.
