S1: Finally, I get to the Nice house. My sister is very happy to see me. I say:“What a big city! I got lost, but a dog and a bird helped me.”

Step 3：教学延伸
What a big city! 多大的城市啊！用“what”来表示感叹句：
1. 感叹句一般是用来表示说话时的喜悦、惊讶等情感。英语感叹句常用"what"和"how"引导，"what"和"how"与所修饰的词置于句首，其它部分用陈述句语序。
2. 由"what"引导的感叹句:"what"意为"多么"用作定语，修饰名词（被强调部分），单数可数名词前要加不定冠词a/an,复数可数名词或不可数名词前不用冠词。这类句子的结构形式是： what+(a/an)+adj.+n.+主语+谓语+(it is).
如：
What a clever girl she is!
多么聪明的姑娘呀！
What an interesting story it is!
多么有趣的故事呀！
What good children they are!
他们是多么好的孩子呀！
What beautiful flowers they are!
多么漂亮的花呀！
3. 由"how"引导的感叹句："how"意为“多么”，用作状语，修饰形容词或副词（被强调部分）。如果修饰形容词，则句中的谓语动词用系动词；如果how修饰副词，则句中的谓语动词用行为动词，这类句子的结构形式是：
How+adj.（adv.）+主语+谓语+(it is).
How cold it is today!
今天多么冷呀！
How nice the pictures are!
多么漂亮的图画呀！
How happy they look!
他们显得多么高兴呀！
How well she sings!
她唱得多好呀！
在表示同一意义时，英语感叹既可用"what"引导，也可用"how"引导。
What a hot day it is!
How hot the day is !
多么热的天气呀！
What tall buildings they are!
How tall the buildings are!
多么高的楼房呀！
What bad weather it is!
How bad the weather is!
多么糟糕的天气呀！
What bright sunshine it is!
How bright the sunshine is!
多么明亮的阳光呀！
5. 感叹句在表示激动强烈的感情时，口语中常常采用省略句，其后面的主语和谓语往往略去不讲。
What a fine day! 多么晴朗的天呀！
What an honest boy! 多么诚实的孩子呀！
What red apples! 多么红的苹果呀！
How cool! 好凉快呀！
How wonderful! 精彩极了！
