They’re patient enough to wait till others move.

In the underground they’re kind enough to give up their seats for pregnant women, elderly people or women with children.

【设计意图：通过谈论英国人的礼貌行为，导入第一个语法点enough to的用法。】

Step 2 Presentation

1. Design a two-day holiday in the UK

  (1) Before leaving

“You are old enough to learn about good manners at home and abroad.”

  (2) Day 1: visit Helen

What’s Helen like?

What did Helen do?

【设计意图：通过设计到英国的旅行，分别介绍两个语法点，第一天到朋友Helen家，自然引导出enough的用法。】

2. Introduce the structure

T: Can you find the similarity? They all have the structure “to be + adjective + enough + to-infinitive”. We can use the structure to describe a person’s personality and abilities.

【设计意图：寻找四个句子的相似点，列出语法结构。】

3. Words used to describe a person’s personality and abilities

4. Explain the use of enough

Step 3 Practice

4. Complete the sentences

T: Complete the sentences by using the adjectives on the left and the phrases on the right.

【设计意图：在阶段练习中侧重了一些基础的语言点的检查，并且在第二组练习中加强了知识的综合运用能力，这样让学生阶梯式攀登，不知不觉掌握所学的语法。】

B  Using too ... to

Step 1 Presentation

1. Day 2: visit London

T: On the second day, Helen showed me around London. On the street, I met many British people.

British people are polite. They don’t push in before others.

British people are gentle. They don’t shout or laugh loudly in public.

British people are patient. They don’t touch you or push past you if you’re in their way.

2. Rewrite the sentences with too ... to

T: We have another way to say the three sentences.

    British people are too polite to push in before others.

    British people are too gentle to shout or laugh loudly in public.

    British people are too patient to touch you or push past you if you’re in their way.

T: Sometimes we need to add “for someone” before the to-infinitive.

The Big Ben is too far away. I can’t go there on my own.

= The Big Ben is too far away for me to go there on my own.

3. Work out the rule

We often use “to be + too + adjective + to infinitive” to express a negative result.

【设计意图：通过设计虚拟的英国的旅行，展示含有too ... to的句型，让学生感悟并推断出规律。】

Step 2 Practice

1. Complete the passage

T: Helen is introducing the places of interest in the UK. Please help her complete the introduction.

【设计意图：通过设计英国景点的介绍，适当练习too ... to句型，让学生在练习所学语法的同时，也了解英国的景点及其文化。】

Step 3 Extended learning

1. Jenny’s diary

T: Jenny has been back to China. Please complete her diary.

T: Pay attention to these two sentences. Can you think of another way to express them?

【设计意图：通过完成日记，练习本节课的语法，同时也延伸出语法间的转换关系。】

2. enough to/too ... to

He is not old enough to do the work.

= He is too young to do the work.

The problem is too difficult for me to work out.
