📚 Identifying and Using Predicate Verbs | 谓语动词的识别与运用

In English grammar, the predicate verb is the heart of a sentence. It tells us what the subject does, what is done to the subject, or what state the subject is in. Mastering the identification and correct use of predicate verbs is essential for building accurate and meaningful sentences.

在英语语法中，谓语动词是句子的心脏。它告诉我们主语做什么、主语承受什么动作，或主语处于什么状态。掌握谓语动词的识别与正确运用，是构建准确且有意义的句子的关键。

1. What Is a Predicate Verb? | 什么是谓语动词？

A predicate verb is the main verb that agrees with the subject and carries tense, voice, and mood. It forms the core of the predicate part of a sentence. For example, in “She runs every morning,” the word “runs” is the predicate verb.

谓语动词是与主语保持一致并承载时态、语态和语气的主动词。它构成句子谓语部分的核心。例如，在“She runs every morning”中，“runs”就是谓语动词。

Unlike non-finite verbs (infinitives, gerunds, and participles), predicate verbs change according to the subject and time. They can be single words or verb phrases such as “is studying” or “has been completed.”

与非谓语动词（不定式、动名词和分词）不同，谓语动词会随着主语和时间的改变而变化。它可以是单个动词，也可以是动词短语，例如“is studying”或“has been completed”。

2. The Subject-Verb Agreement | 主谓一致

The predicate verb must agree with its subject in person and number. A singular subject takes a singular verb; a plural subject takes a plural verb. For instance, “He goes” and “They go” show correct agreement.

谓语动词必须在人称和数上与主语保持一致。单数主语用单数动词，复数主语用复数动词。例如，“He goes”和“They go”就体现了正确的一致关系。

Special cases include indefinite pronouns (“everyone”, “nobody”) which usually take singular verbs, and collective nouns (“team”, “family”) which can be singular or plural depending on meaning.

特殊情况包括不定代词（如“everyone”、“nobody”）通常接单数动词，以及集体名词（如“team”、“family”）根据意义可作单数或复数处理。

3. Tense Recognition | 时态的识别

Predicate verbs express time through tense. The main tenses are present, past, and future, each with simple, continuous, perfect, and perfect continuous aspects. Recognizing the tense helps you understand when an action happens.

谓语动词通过时态来表达时间。主要时态有现在时、过去时和将来时，每种时态又有一般、进行、完成和完成进行等体。识别时态有助于理解动作发生的时间。

For example, “writes” is simple present, “wrote” is simple past, “will write” is simple future, and “has written” is present perfect. Pay attention to auxiliary verbs and verb endings.

例如，“writes”是一般现在时，“wrote”是一般过去时，“will write”是一般将来时，“has written”是现在完成时。注意助动词和动词词尾的变化。

4. Finite vs. Non-Finite Verbs | 限定动词与非限定动词

A predicate verb is always a finite verb. Finite verbs are limited by subject and tense. Non-finite verbs (to write, writing, written) do not act as the main verb of a sentence unless combined with an auxiliary. For example, in “The broken window was repaired,” “was repaired” is the predicate; “broken” is a participle.

谓语动词一定是限定动词。限定动词受主语和时态的制约。非限定动词（to write、writing、written）不能单独充当句子的谓语动词，除非与助动词连用。例如，在“The broken window was repaired”中，“was repaired”是谓语，“broken”是分词。

To identify a predicate verb, ask: Does this verb change when the subject changes? Does it carry tense? If yes, it is likely a predicate verb.

识别谓语动词时，可以问：当主语改变时，这个动词会变吗？它有时态吗？如果答案是肯定的，那么它很可能就是谓语动词。

5. Auxiliary Verbs and Main Verbs | 助动词与实义动词

Predicate verbs can consist of one or more words. In a verb phrase, the last verb is the main verb, and the preceding verbs are auxiliaries. Examples include “is reading”, “has finished”, “will be waiting”, and “should have been informed”.

谓语动词可以由一个或多个词构成。在动词短语中，最后一个动词是实义动词，前面的动词是助动词。例如“is reading”、“has finished”、“will be waiting”和“should have been informed”。

Modal auxiliaries (can, could, may, might, must, shall, should, will, would) are always followed by the base form of the main verb, as in “She must go” not “She must goes.”

情态助动词（can、could、may、might、must、shall、should、will、would）后必须接动词原形，例如应该说“She must go”，不能说“She must goes”。

6. Identifying the Predicate in Questions | 疑问句中的谓语识别

In questions, the predicate verb is often split. For example, in “Is she coming?” the predicate is “is coming,” but “is” appears before the subject and “coming” after it. In “What did you see?” the predicate is “did see,” with “did” as an auxiliary.

在疑问句中，谓语动词常常被拆分。例如，在“Is she coming?”中，谓语是“is coming”，但“is”出现在主语前，“coming”在主语后。在“What did you see?”中，谓语是“did see”，“did”是助动词。

To find the predicate in a question, turn it into a statement. “Is she coming?” becomes “She is coming.” “What did you see?” becomes “You did see what.” Then locate the verb phrase.

要在疑问句中找谓语，可以先把问句变成陈述句。“Is she coming?”变成“She is coming.”，“What did you see?”变成“You did see what.”，然后再找动词短语。

7. Predicate Verbs in Negative Sentences | 否定句中的谓语动词

In negative sentences, “not” is placed after the first auxiliary verb. For example, “They are not playing” and “She has not finished.” If there is no auxiliary, use “do/does/did” plus “not” before the base verb: “I do not like coffee.”

在否定句中，“not”放在第一个助动词之后。例如，“They are not playing”和“She has not finished”。如果没有助动词，就用“do/does/did + not + 动词原形”：如“I do not like coffee”。

Note that “not” is not part of the predicate verb; it is an adverb modifying the verb. The predicate verb in “I do not like” is “do like,” not “do not like.”

注意，“not”不是谓语动词的一部分，它是修饰动词的副词。在“I do not like”中，谓语动词是“do like”，而不是“do not like”。

8. Passive Voice and Predicate Verbs | 被动语态与谓语动词

In passive sentences, the predicate verb consists of a form of “be” plus the past participle of the main verb. For example, “The cake was eaten by Tom.” The predicate is “was eaten.”

在被动句中，谓语动词由“be”的某种形式加上实义动词的过去分词构成。例如，“The cake was eaten by Tom”中，谓语是“was eaten”。

Passive predicates can appear in all tenses: “is made”, “was made”, “has been made”, “will be made”. Recognizing the passive structure helps avoid confusing the past participle as the main predicate.

被动式谓语可以出现在所有时态中：“is made”、“was made”、“has been made”、“will be made”。识别被动结构有助于避免把过去分词误认为谓语动词。

9. Common Mistakes in Predicate Verb Usage | 谓语动词使用的常见错误

One common mistake is using a non-finite verb as a predicate: “He going to school” should be “He goes to school.” Another is incorrect subject-verb agreement: “She don’t like” should be “She doesn’t like.”

常见错误之一是误用非谓语动词作谓语：“He going to school”应为“He goes to school”。另一个是主谓不一致：“She don’t like”应为“She doesn’t like”。

Also avoid missing the auxiliary in continuous or perfect tenses: “They talking now” should be “They are talking now.” Finally, do not change the main verb after a modal: “She can sings” should be “She can sing.”

另外，在进行时或完成时中不能漏掉助动词：“They talking now”应为“They are talking now”。最后，情态动词后实义动词不能变形：“She can sings”应为“She can sing”。

10. Practice Strategy: Finding the Predicate Verb | 练习策略：找到谓语动词

To master predicate verbs, practice with this four-step method. First, find the subject. Second, ask what the subject does or is. Third, locate the verb or verb phrase that carries tense. Fourth, check agreement with the subject.

要掌握谓语动词，可以按以下四步练习。第一步，找到主语。第二步，问主语做了什么或处于什么状态。第三步，找出携带时态的动词或动词短语。第四步，检查主谓是否一致。

Apply this method to sentences in reading passages. Underline every predicate verb and try to replace the subject to see if the verb changes. This builds a strong instinct for predicate verb recognition.

在阅读文章中运用这个方法，划出每一个谓语动词，并尝试更换主语看看动词是否变化。这能帮助你建立起识别谓语动词的强烈语感。
