7 English Grammar Rules You Should Know

7 English Grammar Rules You Should Know 7 English Grammar Rules You Should Know 7 English Grammar Rules You Should Know By Mark Nichol This post outlines seven general areas of grammar and syntax that writers must be familiar with to enable them to write effectively. 1. Subject-Verb Agreement Use singular verbs for singular subjects and plural verbs with plural subjects. A verb should agree with its subject, not with an intervening modifying phrase or clause: â€Å"The box of cards is on the shelf.† Singular verbs are appropriate with the following parts of speech: indefinite pronouns: â€Å"Everyone is here† uncountable nouns: â€Å"The rain has stopped† inverted subjects: â€Å"Where is the car?† subjects plural in form but singular in meaning: â€Å"Statistics [the academic subject] is boring,† but â€Å"Statistics [sets of data] are sometimes misleading† compound subjects: â€Å"Breaking and entering is different than burglary† the constructions â€Å"the only one of those (blank) who . . . ,† â€Å"the number of (blank) . . . ,† â€Å"every (blank) . . . ,† and â€Å"many a (blank) . . .† a measurement when considered as a unit: â€Å"Three months is a long time to wait† collective nouns: â€Å"The team is ready for the game† (but if referring to all individual members of a collective, reword for clarity, as in â€Å"The members of the team stand behind the coach’s decision†) 2. Nominative and Objective Pronouns and Reflexive Pronouns Pronouns are sometimes used erroneously when a phrase contains more than one object. For example, although â€Å"My sister and I are coming† is correct because â€Å"My sister and I† is the subject and therefore the nominative I is appropriate, â€Å"He invited my sister and I† is wrong because â€Å"my sister† and I are the objects, and the pronoun should be in objective form (me, not I). Reflexive pronouns, compound of a pronoun and -self, are correct only if they are associated with an antecedent pronoun, as in â€Å"I did it myself†; â€Å"Contact John or myself† is an error because there is no previous reference to the self-identifying person. 3. Dangling Participles When a sentence begins with an incomplete phrase or clause, the person, place, or thing it modifies must immediately follow it as the subject of the main clause, or the introductory phrase or clause must be rewritten. For example, in â€Å"Rolling down the slope, my eyes beheld a curious sight,† the writer intends to express that he or she was rolling down the slope, but the subject of the sentence is â€Å"my eyes,† leading to the impression that the rolling was performed by the eyes, not the individual. To resolve the problem, amend the sentence to â€Å"Rolling down the slope, I beheld a curious sight† or â€Å"As I rolled down the slope, my eyes beheld a curious sight.† 4. Misplaced Modifiers A modifying phrase should immediately follow the word or phrase it modifies. For example, in the sentence â€Å"I overheard that they’re getting married in the rest room,† because â€Å"in the rest room† follows â€Å"getting married,† the reader is given the impression that the nuptials will take place in the rest room. However, â€Å"in the rest room† modifies the subject, â€Å"I overheard,† so those two phrases should be adjacent: â€Å"I overheard in the rest room that they’re getting married.† 5. Incomplete Sentences Many justifications exist for sentence fragments, but they are best used judiciously and in such a way that it is clear to the reader that the writer is deliberately writing an incomplete sentence, and not obliviously making an error. 6. Phrase and Clause Lists In-line lists, those presented within the syntax of a sentence, should be structured to be grammatically consistent. For example, the sentence â€Å"Insights are actionable, adaptive, and help achieve the desired objectives† is erroneously constructed because are serves the first adjective and help is associated with achieve, but adaptive cannot share are with actionable unless a conjunction rather than a comma separates them: â€Å"Insights are actionable and adaptive and help achieve the desired objectives.† If a sentence, unlike in this revision, is to remain in list form, each list element must follow parallel construction, as in the revision of â€Å"Teapots may be embellished with landscapes, scenes from paintings, historical figures, or natural elements such as orchids or bamboo† to â€Å"Teapots may be embellished with landscapes, scenes from paintings, portraits of historical figures, or depictions of natural elements such as orchids or bamboo,† where each element must refer to representations of phenomena rather than the phenomena themselves. 7. Restrictive and Nonrestrictive Phrases and Clauses Although the use of which in a sentence such as â€Å"She prefers a job which is more stable† is technically correct in American English (and ubiquitous in British English), careful writers will help their readers by maintaining this distinction between which and that: Use the former with a nonrestrictive phrase â€Å"She prefers a job, which is more stable than freelance work† (what follows the comma and which is not essential to the sentence) and use the latter with a restrictive phrase â€Å"She prefers a job that is more stable† (â€Å"that is more stable† is an essential part of the sentence).

The Color Chemistry That Makes Mars Red

The Color Chemistry That Makes Mars Red When you look up in the sky, you can recognize Mars by its red color. Yet, when you see photos of Mars taken on Mars, many colors are present. What makes Mars the Red Planet and why doesnt it always look red close-up? The short answer for why Mars appears red, or at least red-orange, is because the Martian surface contains a large amount of rust or iron oxide. The iron oxide forms a rust dust that floats in the atmosphere and sits as a dusty coating across much of the landscape. Why Mars Has Other Colors Up Close The dust in the atmosphere causes Mars to appear very rusty from space. When viewed from the surface, other colors are apparent, in part because landers and other instruments dont have to peer through the whole atmosphere to see them, and partly because rust exists in colors other than red, plus there are other minerals on the planet. While red is a common rust color, some iron oxides are brown, black, yellow and even green! So, if you see green on Mars, it doesnt mean there are plants growing on the planet. Rather, some of the Martian rocks are green, just like some rocks are green on Earth. Where Does the Rust Come From? So, you may be wondering where all this rust comes from  since Mars has more iron oxide in its atmosphere than any other planet. Scientists are not completely sure, but many believe the iron was pushed up by the volcanoes that used to erupt. Solar radiation caused atmospheric water vapor to react with the iron to form iron oxides or rust. Iron oxides also may have come from iron-based meteorites, which can react with oxygen under the influence of solar ultraviolet radiation to form iron oxides.
