Mastering Sentences with 是 (Shì) in Mandarin Chinese

The verb 是 (shì) is one of the most fundamental and frequently used verbs in Mandarin Chinese. It functions similarly to the English verb “to be,” serving as a link between the subject and its description or identification. Understanding how to use 是 (shì) correctly is essential for forming basic sentences in Chinese. This article will provide a comprehensive guide on how to use 是 (shì) in various contexts, along with examples and practice exercises to help you master its usage.

Basic Usage of 是 (Shì)

The primary function of 是 (shì) is to link the subject of a sentence with its predicate, which can be a noun, pronoun, or adjective.

Structure:

• Subject + 是 (shì) + Predicate

Examples:

• 我是学生。(Wǒ shì xuéshēng.) – I am a student.
• 他是老师。(Tā shì lǎoshī.) – He is a teacher.
• 这是我的书。(Zhè shì wǒ de shū.) – This is my book.

Using 是 (Shì) with Nouns

When 是 (shì) is used to link the subject to a noun, it indicates that the subject is identified or classified as the noun.

Examples:

• 她是医生。(Tā shì yīshēng.) – She is a doctor.
• 我们是朋友。(Wǒmen shì péngyǒu.) – We are friends.
• 北京是中国的首都。(Běijīng shì Zhōngguó de shǒudū.) – Beijing is the capital of China.

Using 是 (Shì) with Pronouns

是 (shì) can also link the subject to a pronoun, emphasizing identification or relation.

Examples:

• 那个人是我。(Nàgè rén shì wǒ.) – That person is me.
• 这些是你的东西。(Zhèxiē shì nǐ de dōngxi.) – These are your things.
• 那是我们的家。(Nà shì wǒmen de jiā.) – That is our home.

Using 是 (Shì) with Adjectives

While 是 (shì) is typically used with nouns and pronouns, it is not used directly with adjectives to describe a subject’s state or quality. Instead, the adjective usually follows the subject directly without 是 (shì). However, 是 (shì) can be used in sentences to emphasize the state or condition when combined with other structures.

Examples:

• 他很聪明。(Tā hěn cōngmíng.) – He is very smart. (Note: 很 (hěn) is used instead of 是 (shì).)
• 这本书是新的。(Zhè běn shū shì xīn de.) – This book is new. (Here, 是 (shì) emphasizes the state with a descriptive particle 的 (de).)

Forming Questions with 是 (Shì)

To form questions using 是 (shì), you can add the particle 吗 (ma) at the end of the statement, or use question words such as 什么 (shénme) for “what” or 谁 (shéi) for “who.”

Examples:

• 你是学生吗？(Nǐ shì xuéshēng ma?) – Are you a student?
• 他是谁？(Tā shì shéi?) – Who is he?
• 这是什么？(Zhè shì shénme?) – What is this?

Forming Negative Sentences with 是 (Shì)

To negate a sentence with 是 (shì), use the negative particle 不是 (bú shì) before the predicate.

Examples:

• 我不是老师。(Wǒ bú shì lǎoshī.) – I am not a teacher.
• 这不是我的书。(Zhè bú shì wǒ de shū.) – This is not my book.
• 他不是学生。(Tā bú shì xuéshēng.) – He is not a student.

Emphasizing with 是 (Shì)

是 (shì) can also be used to emphasize a specific element in a sentence, especially in contrastive sentences.

Examples:

• 我是昨天来的。(Wǒ shì zuótiān lái de.) – I came yesterday.
