Ⅳ. Special difficulties. 难点。
A) 朗读并口头翻译下面句子或短语，然后完成小结。
1. 动名词是一种非限定动词形式，它在句子中可以起名词的作用。动名词作主语时，后面跟谓语动词单数形式，因为动名词在语法功能上相当于一个单数名词。
1) Healthy eating is important for a healthy body and mind.
2) Eating three meals a day is important.
2. it 作形式主语或形式宾语时，是一种语法结构，用于避免句子头重脚轻。句中 it 作形式主语或形式宾语，真正的主语或宾语为动词不定式 to do。
1) It is easy to feel sleepy.
2) We find it hard to focus on our work or studies if we don't eat breakfast.
3. too many, too much 和 much too
读下列短语，总结 too many, too much 和 much too 的用法。
too much milk too much sugar too much rice too many beans
too many cookies much too busy much too easy much too hard
小结：too much 后加“”，表示“太多……”；too many 后加“”，表示“太多…… ”；much too 后加“”，表示“太……”。
4. too... to... 意为“太……而不能”。
1) Maybe they don't feel hungry in the morning, or they are too busy to eat anything.
2) Alice is too shy to talk in front of lots of people.

由于没有具体给出2a-2c的题目内容，我将假设一个典型的七年级下册Section B的人教版英语题目场景来构建答案。通常这类题目会涉及填空、补全对话或短文，然后基于这些完成修改和重写。
假设题目内容如下：

A: What time ______ you ______ (get) up?
B: I ______ (get) up at 6:30 a.m.

解答：
2a:
1. go
2. has
3. play
2b:
A: What time do you get up?
