There is a lot more to grammar than one may think. As a whole, grammar encompasses the plethora of rules by which sentences are strung together. English grammar tests can contain a wide variety of questions about the correct usage of verbs or elements of speech. This can include past tense versus present tense, participles, gerunds and the correct usage of pronouns. Often times, questions asked
. on an English grammar test require the student to conjugate the correct form of one or more words to form a coherent sentence, so the rules of inflection in the English language are important to know. For example, take the word, "sit." One could say, "He sits by the table," but if the subject of the sentence is plural, one must remove the "s" at the end of the verb. "They sit by the table. " English grammar tests are also notorious for asking questions pertaining to the correct usage of independent and dependent clauses in a sentence. The test may ask the student to discern between complete sentences and sentence fragments or run-on sentences.It is also very helpful to know how to diagram a sentence. This can prove quite tricky when the sentence is long or contains subordinate clauses. Each sentence has three components, which are either present in the sentence or understood in context. These three components are subject, verb and direct object. The way in which they interact allows one to determine whether the sentence is active or passive, an important concept in writing. One should limit their use of the passive tense to no more than ten percent of an academic paper. All of these concepts are enormously valuable when it comes to formal writing and very relevant to everyday speech.For more information about English grammar tests, please see:http://grammarbook.com/http://grammar.ccc.commnet.edu/grammar/ More reference links: http://grammarbook.com/ http://grammar.ccc.commnet.edu/grammar/
