Question 81: How can I test for sentence fragments?
Answer: A sentence fragment is a phrase or dependent clause that has been punctuated as if it were a complete sentence.
Test sentences for completeness:
1. Is there a verb?
If yes, proceed to 2.
If no, the clause cannot be a sentence.
2. Is there a subject?
If yes, proceed to 3.
If no, the clause cannot be a sentence.
3. Does the phrase begin with a subordinating conjunction or relative pronoun (a word that tells more about or qualifies a character or an action--although, because, while, that, which, if, etc....)?
If yes, the clause is dependent, not independent. It isn't a sentence.
If no, it is a sentence.
问题81：怎样检查句子是否完整？
回答：一个不完整的句子成分就是一个被用标点当作完整句子点开的短语或非独立句。要检查句子的完整性可通过以下几个步骤：
1. 有动词吗？
如果有，进行到步骤2；如果没有，这就不是一个句子。
2. 有主语吗？
如果有，进行到步骤3；如果没有，这就不是一个句子。
3. 短语是以连接词或关系代词开头的吗？（就是补充说明或限制修辞人物或动作的词，如：although, because, while, that, which, if等...)?
如果有，子句就是非独立的，也就是说这不是一个句子。如果没有，那就是一个句子。
