Declarative
陈述句

A declarative sentence "declares" or states a fact, arrangement or opinion. Declarative sentences can be either positive or negative. A declarative sentence ends with a period (.).
陈述句陈述事实、安排或观点的陈述句。陈述句可以是肯定句，也可以是否定句。陈述句以句号（.）结尾。

我在火车站等你。/太阳从东方升起。/他起得不早。

Imperative
祈使句

The imperative form instructs (or sometimes requests). The imperative takes no subject as 'you' is the implied subject. The imperative form ends with either a period (.) or an exclamation point (!).
命令式形式指示（或有时请求）。祈使句不带主语，因为“你”是隐含主语。命令式形式以句点（.）或感叹号（！）结尾。

Open the door./Finish your homework/Pick up that mess.
开门。/做完作业/收拾残局。

Interrogative
疑问句

The interrogative asks a question. In the interrogative form, the auxiliary verb precedes the subject which is then followed by the main verb (i.e., Are you coming ....?). The interrogative form ends with a question mark (?).
疑问句用于问一个问题。在疑问句中，助动词先于主语，主语后接主语（即，你要来吗…？）。疑问句以问号（？）结尾。

你在法国住了多久？/公共汽车什么时候开？/你喜欢听古典音乐吗？

Exclamatory
感叹句

The exclamatory form emphasizes a statement (either declarative or imperative) with an exclamation point (!).
感叹词形式强调带有感叹号（！）的语句（声明性或命令性）。

Hurry up!/That sounds fantastic!/I can't believe you said that!
快点！/听起来棒极了！/真不敢相信你这么说！
