HSK 5 Fixed Phrase: X是它，Y也是它

Core Meaning and Rhetorical Function

In the HSK 5 syllabus outline, the fixed phrase X是它，Y也是它 is listed under fixed formats and phrases. Please note that level labels in the supplied 2025-11 syllabus outline define the scope of this study material rather than guaranteeing which test version a local test center currently administers.

Literally translating to "X is it, and Y is also it," this pattern points back to a single topic already introduced in the conversation or sentence. Instead of simply listing two qualities of an object, the speaker treats the two roles or outcomes (X and Y) as separate grammatical subjects and reveals that both point to the exact same entity (它). This creates a strong rhetorical focus, often highlighting irony, ubiquity, or mixed feelings.

Sentence Structure and Slot Patterns

Because X and Y sit before the verb 是 (to be) and equate to the pronoun 它 (it), the elements filling X and Y must function like nouns or nominalized clauses. In natural Chinese, native speakers fill these two slots in two main ways:

• Nominalized phrases ending in 的: When X and Y describe specific actions performed by the referent (such as "the one that wakes us up" or "the one that makes me lose sleep"), a verb phrase plus 的 turns the action into an agent noun phrase.
• Keep the identification clear. In 提高效率的是它, 的 makes the phrase refer to the thing that improves efficiency. Some rhetorical expressions allow compression, but four characters alone do not make an arbitrary verb phrase equivalent to an actor or source.
• Make the reference clear: the listener or reader should be able to identify what 它 refers to from the sentence or surrounding context.

Natural Usage Contexts and Limits

This fixed phrase is rarely used for dry, neutral facts. You would not typically use it to say a table is both brown and heavy. Instead, it thrives in expressive essays, speeches, and everyday complaints or praise where the speaker wants to emphasize a paradox or an all-encompassing role.

• Expressing duality or mixed feelings: Ideal when the same habit, tool, or policy brings both a major benefit (X) and a frustrating drawback (Y).
• Highlighting constant presence: Useful when showing that an object accompanies someone from morning to night, or from the beginning to the end of a process.
• Pronouns in writing: the supplied pattern uses 它 for a thing, animal or abstract referent. When the intended referent is a person, adapt the written pronoun to 他 or 她 as appropriate. In Mandarin the three pronouns have the same pronunciation, tā.

Contrast: X是它，Y也是它 vs. 既……又……

The main difference from 既……又…… is how information is organized. 既……又…… commonly keeps the object as the topic and adds two predicates. X是它，Y也是它 presents two roles first and repeatedly identifies their shared source. Either construction can carry emotion; 既……又…… is not inherently neutral.

Common Learner Mistake: Dropping 的 in Agent Clauses

If a phrase is intended to mean “the thing that did this,” 的 helps turn the activity description into a referring expression: 陪我度过低谷的是它. The issue is what the phrase refers to, not a mechanical rule that short phrases omit 的 while long phrases or personal objects require it. In the shop example, add 的 in both halves to identify the shop clearly.

Adding 的 transforms "accompany me through a low point" into "the one that accompanied me through a low point," allowing it to link grammatically with 是它.
