英语感叹句what和how的用法

英语中，感叹句用来表达强烈的情感或惊讶。"What"用于感叹名词，"how"用于感叹形容词、副词或动词。例如，"What a beautiful day!"（多么美好的一天！）和"How quickly you run!"（你跑得真快！）。使用时，"what"后跟名词，"how"后跟形容词或副词，再加主语和谓语。

Exclamatory sentences are used to express emotions such as joy, surprise, or astonishment. In English, these sentences are often introduced by "what" or "how." The key difference lies in their function within the sentence: "what" modifies nouns, which can be preceded by articles and adjectives, while "how" modifies adjectives, adverbs, or verbs.

Usage of "What" in Exclamatory Sentences

Exclamatory sentences led by "what" can be structured in two ways:

• What + a/an + (adjective) + singular countable noun + subject + verb!
  Example: What a fine day it is!
• What + noun phrase + subject + verb!
  Example: What kind women they are!

Additionally, "what" can be used with plural countable nouns or uncountable nouns:

• What + (adjective) + plural countable noun or uncountable noun + subject + verb!
  Example: What nice music it is!

Usage of "How" in Exclamatory Sentences

Exclamatory sentences led by "how" typically modify adjectives, adverbs, or verbs and can be structured as follows:

• How + adjective (adverb) + subject + verb!
  Example: How hard the workers are working!
• How + subject + verb!
  Example: How time flies!

It's important to note that "how" and "what" can sometimes be interchangeable, with the same meaning:

• How clever a girl she is! = What a clever girl she is!
• What delicious cakes these are! = How delicious these cakes are!

In contexts of strong emotional expression, exclamatory sentences led by "how" or "what" can be elliptical, omitting the subject and verb:

• How wonderful!
• What a fine day!

Exclamatory sentences, which inherently convey strong emotions, generally do not include words like "very," "rather," "quite," or "extremely" to avoid redundancy:

• How very fast he runs!
• What extremely beautiful flowers they are!
