感叹句（Exclamatory sentence）：表达强烈情感或惊讶的句子，常以感叹词开头，结尾通常有一个感叹号。例如："What a beautiful sunset!"（多美丽的日落啊！）

命令句（Imperative sentence）：用于发出命令、请求、建议或指示的句子。通常省略了主语，动词直接在第一位。例如："Close the door."（关上门。）

陈述句（Declarative sentence）：陈述一个事实或提供信息的句子，是最常见的一种语气。它们以肯定形式陈述，并以标点符号结尾，通常是一个句点。例如："I like to read books." （我喜欢读书。）

区分这些类型可以根据以下特征：
- 感叹句通常以感觉强烈且带有惊讶或赞美之情来表达。
- 命令句具有明确的指示性质，并且经常省略主语。
- 陈述句提供信息并描述现实情况。

How to differentiate between an exclamatory, imperative, and declarative sentence:

Exclamatory Sentence: An exclamatory sentence expresses strong emotions or surprise. It often starts with an exclamation word and ends with an exclamation mark. For example: "What a beautiful sunset!"

Imperative Sentence: An imperative sentence is used to give commands, make requests, or provide instructions. It usually omits the subject, and the verb comes first. For example: "Close the door."

Declarative Sentence: A declarative sentence states a fact or provides information. It is the most common type of sentence and is in an affirmative form with a punctuation mark at the end, typically a period. For example: "I like to read books."

To differentiate between these types:
- Exclamatory sentences often express strong emotions with surprise or admiration.
- Imperative sentences have explicit instructive nature and frequently omit the subject.
- Declarative sentences provide information and describe real situations.
