五下知识点 1.感叹句
What引导的感叹句:主要修饰名词,根据名词的可数、不可数以及单复数形式,what感叹句可分为两种情况:
(1)What+a/an+形容词+可数名词单数+主语+谓语!
What a beautiful flower it is!
(2)What+形容词+不可数名词或可数名词复数+主语+谓语!
What beautiful flowers they are!
What fine weather it is!
How引导的感叹句:主要修饰形容词和副词,结构是:How +形容词、副词+主语+谓语!
How beautiful the flower is.
How fast he runs!
注意:What和How引导的感叹句,句末“主语+谓语”有时在口语上是可省的。
What a beautiful flower!
How beautiful!
