Thank you for writing, Kyaw. Before we answer your question, we need to review some terms and their meanings.
谢谢你写信，Kyaw。在回答您的问题之前，我们需要回顾一些术语及其含义。
A clause is a grammar unit organized around a verb phrase . A clause is made of two parts: a subject (the topic of a clause) and a verb (what is said about the topic).
从句是围绕动词短语组织的语法单元。子句由两部分组成：主语（子句的主题）和动词（有关主题的内容）。
For example, “we laughed” is a clause. “We” is the subject, and “laughed” is the verb.
例如，“我们笑了”是一个从句。 “我们”是主语，“笑”是动词。
“In the morning” is not a clause because it does not have a verb.
“早上”不是一个从句，因为它没有动词。
There are two main kinds of clauses. Independent clauses are not dependent on any other clause. They are sentences on their own. “We laughed” is an independent clause.
子句主要有两种类型。独立子句不依赖于任何其他子句。它们本身就是句子。 “我们笑了”是一个独立子句。
A dependent clause depends on an independent clause. It cannot be a sentence on its own. “Before I went,” for example, is a dependent clause because, although it has a subject and a verb, it requires additional information to be a full thought.
从属子句依赖于独立子句。它不能单独成为一个句子。例如，“Before I gone”是一个从属子句，因为尽管它有一个主语和一个动词，但它需要额外的信息才能成为一个完整的想法。
We can sort sentences into three groups by the clauses they have. A sentence must have at least one independent clause. The independent clause is a simple sentence. For example:
我们可以根据句子所包含的从句将句子分为三组。一个句子必须至少有一个独立子句。独立子句是一个简单的句子。例如：
It snowed last night.
昨晚下雪了。
When a sentence has two or more independent clauses, it is a compound sentence. For example:
当一个句子有两个或两个以上独立从句时，它就是复合句。例如：
I went to the party, but he stayed home.
我去参加聚会，但他留在家里。
When a sentence has at least one independent clause as well as one or more dependent clauses, it is a complex sentence. For example:
当一个句子至少有一个独立子句和一个或多个从属子句时，它就是一个复杂的句子。例如：
I’ll call you when I get home.
我到家后会给你打电话。
Now, to answer your question, Kyaw! Your example has only one clause. This means it is a simple sentence, not a complex sentence.
现在，回答你的问题，Kyaw！你的例子只有一个子句。这意味着这是一个简单的句子，而不是一个复杂的句子。
There are seven simple sentence patterns in English, but we can talk about those another day.
英语有七种简单的句型，但我们可以改天再讨论。
We hope this explanation has helped you, Kyaw.
我们希望这个解释对您有所帮助，Kyaw。
