主语从句句式英语作文
英文回答：
A subject clause is a dependent clause that functions
as the subject of a sentence. It begins with a
subordinating conjunction, such as "that," "which," "who," "whom," or "whose," and contains a verb. Subject clauses
can be used to provide additional information about the subject of the main clause.
For example, in the sentence "The student who studies hard will succeed," the subject clause "who studies hard" provides additional information about the subject "student." It tells us that the student who will succeed is the one who studies hard.
Subject clauses can also be used to introduce a noun or pronoun that is the subject of the main clause. For example, in the sentence "Whoever wins the lottery will be rich,"
the subject clause "whoever wins the lottery" introduces
the noun "winner," which is the subject of the main clause.
Subject clauses can be either restrictive or nonrestrictive. Restrictive clauses are essential to the meaning of the main clause and cannot be removed without changing the meaning of the sentence. Nonrestrictive clauses provide additional information that is not
essential to the meaning of the main clause and can be removed without changing the meaning of the sentence.
For example, in the sentence "The student who studies hard will succeed," the subject clause "who studies hard"
is restrictive because it is essential to the meaning of the sentence. If we remove the subject clause, the sentence would no longer make sense. However, in the sentence "The student, who studies hard, will succeed," the subject clause "who studies hard" is nonrestrictive because it provides additional information that is not essential to the meaning of the sentence. If we remove the subject clause, the sentence would still make sense.
Subject clauses are a versatile grammatical tool that
can be used to add complexity and nuance to writing. By understanding how to use subject clauses, writers can effectively communicate their ideas and create clear and concise prose.

主语从句是一种充当句子主语的从属从句。

它以一个连词开头，例如"that"、"which"、"who"、"whom"或"whose"，并包含一个谓语动词。

主语从句可用于提供有关主句主语的更多信息。

例如，在句子"努力学习的学生会取得成功"中，主语从句"努力
学习的学生"提供了有关主语"学生"的更多信息。

它告诉我们，将获
得成功的人是那些努力学习的人。

主语从句还可用于介绍一个名词或代词，即主句的主语。

例如，在句子"无论谁赢得彩票都将变得富有"中，主语从句"无论谁赢得彩票"介绍了名词"获奖者"，即主句的主语。

主语从句可以是限定性的或非限定性的。

限定性从句对于主句
的含义至关重要，若不改变句子含义，则无法将其删除。

非限定性
从句提供的信息对于主句的含义并不重要，且若不改变句子含义，
则可以将其删除。

例如，在句子"努力学习的学生会取得成功"中，主语从句"努力学习的学生"具有限定性，因为它对于句子的含义至关重要。

如果我们删除主语从句，句子将不再有意义。

然而，在句子"努力学习的学生会取得成功"中，主语从句"努力学习的学生"具有非限定性，因为它提供了对于句子含义并不重要的附加信息。

如果我们删除主语从句，句子仍然有意义。

主语从句是一种灵活的语法工具，可用于增加写作的复杂性和细微差别。

通过理解如何使用主语从句，作者可以有效地传达自己的思想，并创建清晰简洁的散文。
