Converting Fragments to Full Sentences
“句子片段”group of words that that has been punctuated as a full sentence, but that does not actually meet the requirements for a full sentence. The sentences below are examples of fragments:
* Although the office closes at 4:30 p.m.
* Becausenearly every student brings a laptop or other device to class.
* Meaning this essay will focus on recent developments in classroom technology.
* Which indicates a significant increase in performance.
Fragments can be confusing if readers cannot determine whether the fragment’s meaning is meant to connect to the sentence that precedes or follows it, as in this example:
A strong, reliable wireless network on campus is important. Because nearly every student brings a laptop or other device to class. The university should have a policy to guide internet use during tests.
This handout will help you learn how to recognize sentence fragments in your writing and convert those fragments to full sentences.
Understanding What a Sentence Fragment Is
To be a full sentence, a group of words must include anindependentclause, which consists of a subject, its verb, and any remaining elements. In the examples of independent clauses below, the subject is inboldface; the verb isunderlined,剩下的elements of the sentence are in regular type:
The artistis paintinga beautiful landscape.
Theycan distortour understanding of freedom.
The committeewill voteto hire the candidate.
Tens of thousands of incidentsremainundiscovered.
Most sentence fragments occur when adependent clauseis punctuated as a full sentence. Independent clauses and dependent clauses look and sound a lot alike, which is why sentence fragments occur. Like an independent clause, a dependent clause also includes a subject and its verb. The difference is that a dependent clause begins with a subordinating word or phrase like “although,” “if,” “when,” or “which.” This subordinating word suggests that the clause’s meaning is not complete, and it makes the clausedependent.
Such a clause cannot be a complete sentence, as the term “dependent” suggests. It should be connected to an independent clause, usually with a comma.
The examples below are dependent clauses. The subordinating word or phrase appears initalics:
Ifthe networkcan supportadditional devices
Becausetheydistortour understanding of freedom
Whenthe committeewill voteto hire the candidate
Meaning thattens of thousands of incidentsremainundiscovered
While each of these clauses does include a subject and its verb, it begins with a subordinating word or phrase. As such, each is a dependent clause. If a dependent clause is punctuated as a full sentence, it is called a sentence fragment.
Converting Fragments
You can use two strategies for converting sentence fragments:
1) Join the fragment to the sentence it logically belongs to. This is usually done by replacing the period that separates the fragment from the sentence with a comma. |
Use this strategy if the fragment and the sentence it will join are not very lengthy. |
2) Revise the fragment into an independent clause. |
Use this strategy if joining the fragment to the sentence will create a very long sentence. |
The example below illustrates both approaches for converting a sentence fragment. The sample passage includes two independent clauses plus one sentence fragment (marked with an asterisk):
Reporting cyber incidents by contractors and agencies is a crucial first step in stopping a cyberattack. However, OMB has found that on average, agencies detect only sixty-three percent of cybersecurity incidents. *Meaning that tens of thousands of incidents go undiscovered.
Option 1: Join the fragment to the independent clause it belongs to: |
Reporting cyber incidents by contractors and agencies is a crucial first step in stopping a cyberattack. However, OMB has found that on average, agencies detect only sixty-three percent of cybersecurity incidents, meaning that tens of thousands of incidents go undiscovered. |
Option 2: Revise the fragment into an independent clause: |
Reporting cyber incidents by contractors and agencies is a crucial first step in stopping a cyberattack. However, OMB has found that on average, agencies detect only sixty-three percent of cybersecurity incidents. This means that tens of thousands of incidents go undiscovered. |
Identifying Fragments
As discussed above, most fragments occur when a dependent clause is punctuated as a full sentence. To spot fragments in your own writing, it can be helpful to know which words signal the presence of a dependent clause. There are three types of such words: subordinating conjunctions, relative pronouns, and participial phrases. They are listed below:
Types of Subordinating Words & Phrases |
||
Subordinating Conjunction |
after, although, as, because, before, even though, if, once, since, though, unless, whereas, while |
Afterit stops raining, we should go for a walk. I draft the body paragraphsbeforeI write my introduction. |
Relative Pronoun |
that, which, who, whom, whoever, whomever, whose |
I can’t wait to drive my new car,whichI’m buying later today. We reached out to her brother,whois a teacher for Fairfax County schools. |
Participial Phrase |
meaning that, being that, indicating that, resulting in |
The forecast is for snow tomorrow,meaning thatcampus could be closed. |
To spot sentence fragments in your writing, look for dependent clauses (clauses that begin with one of the types of words above) that have not been joined to a full sentence.
Practice
Use the strategies described above to identify fragments in the passage below and convert them to full sentences.
