【设计说明】语言不仅是文化的载体，更是思维的媒介。教授语言的最终目的不能仅限于知识的传递，因为"生有涯而知无涯"。因此，在语言知识教授的同时，应该兼顾运用与思维的发展。基于这样的想法，在此处的"Discussion"中，有意就"一国出现多种官方语言"的问题让学生展开了探索性的思考，旨在提高学生主动性思维的质量，使英语的学习能真正成为一种能活用的语言。

Step 3 Formal and informal English

English is widely used nowadays. And it can also be divided into formal and informal English. Ask the students to read the paragraphs on page 26. (task-based reading)

Task: Read and fill the form.

(The form is designed to help the students tell the differences between formal and informal English. The students are supposed to summarize the differences.)

Ask the students to read the examples on the textbook and finish the exercise after class.

【设计说明】正式与非正式英语，只是一个相对且较模糊的概念。就高中学生英语语料的积累来看，学生很大程度上还不可能达到很好地体会与掌握两者间差异的水平。所以在处理这部分教材时，只作了简单的介绍，主要是让学生了解差异的存在，在以后学习和使用的过程中，能有意识地注意两者的差别，并选择合适的语言进行表达。

Step 4 Discussion:

1: English is the most commonly used language in the world. Ask the students to think of other things that also help to achieve better understanding between people from different countries or different cultures.

(This question is not easy to answer. So before the discussion, an example is given.)

2: Show the students a picture. (A little girl is enjoying an ice-cream with her pet dog.)

Ask the students to answer why the girl still wants to share the ice-cream with her dog though it is supposed to be dirty to do so. (Because the girl loves her dog.)

Have a discussion with the students why people from different countries will feel the same when they see the same picture. (Because we all can understand the love between the pretty girl and her lovely dog.)

Get a conclusion: Love is universally appreciated.

So besides English, the language of love also can be understood across the world.

3: Group work (Ask the students to discuss it in groups.)

Allow the students to express their ideas freely.

4: Give the students some possible answers:

Art, food, music and smile are possible answers.

Summary：

Sometimes it's very difficult for us to communicate with each other by using one language. However, the people across the world have one thing in common. That is: we all value truth, kindness and beauty. We all value quiet and peace. We all value happiness and harmony. Whatever language we speak, we are sure to live in this world, our happy family.

Show the summary on the screen and ask the students to read together.
