A sentence fragment is a group of words that resembles a sentence. It will start with a capital letter and have ending punctuation; however, it is neither an independent clause nor a complete idea.

Explanation: There is a subject, but no predicate. Therefore, it’s a fragment.

A sentence is a group of words that are put together to mean something. A sentence is the basic unit of language which expresses a complete thought. It does this by following the grammatical basic rules of syntax. A complete sentence has at least a subject and a main verb to state (declare) a complete thought.

We use only if to express a strong condition, often an order or command, to mean ‘on the condition that’. It has an opposite meaning to ‘except if’: Payment will be made only if the work is completed on time. Alright I’ll come but only if I can bring a friend with me.

when or while We use both when and while as subordinating conjunctions to introduce adverbial clauses of time. They mean during the time that and indicate that something is or was happening when something else occurred: The prisoners escaped when / while the prison warders were eating their lunch.

We use do/does or is/are as question words when we want to ask yes/no questions. We use does and is with third person singular pronouns (he, she, it) and with singular noun forms. We use do and are with other personal pronouns (you, we they) and with plural noun forms.

Do as the helping verb is used in questions and positive sentences in the present simple and past simple tenses. Do as main verb: Be as the helping verb is followed by the main verb + ing.

“She does her homework before she goes out to play.” “She does many after school activities.” “He does a lot of chores around the house.” “He does not want to move to another school.”
