Starting a sentence with by is fine. The subordinate phrase is a prepositional one which acts as an adverb to modify the verb consume.

It has been said that prepositions should never start or end a sentence. The best way to start a sentence with a preposition is in an introductory phrase. When you do this, you should usually place a comma after the phrase.

All sentences begin with a capital letter (also called an upper-case letter). All sentences end with what’s called a terminal punctuation mark: either a period (also called a full stop), a question mark, or an exclamation mark. Periods mark the end of statements, indirect questions, and most imperative sentences.

A sentence is a group of words you say or write down. Sentences always start with a capital letter and usually end with a period. This doesn’t mean that everything that starts with a capital letter and ends with a period is a sentence, though. For instance, look at this phrase: Guzzle Brian dog late.

Restate the main idea/thesis, summarize your body paragraphs, and leave readers with a lasting impression of what the paper was about (i.e. provide reasoning for why readers should care about what you just told them).

You should start a new paragraph when:

• When you begin a new idea or point. New ideas should always start in new paragraphs.
• To contrast information or ideas.
• When your readers need a pause.
• When you are ending your introduction or starting your conclusion.

As a start, here are 13 introductory strategies accompanied by examples from a wide range of professional writers.

1. State Your Thesis Briefly and Directly.
2. Pose a Question Related to Your Subject.
3. State an Interesting Fact About Your Subject.
4. Present Your Thesis as a Recent Discovery or Revelation.

The topic sentence is usually the first sentence in a paragraph. It is introductory, meaning it should not include details, rather, it should introduce the main idea which will be supported by the rest of your paragraph.

How to Write an Effective Classification Essay

1. Determine the categories. Be thorough; don’t leave out a critical category.
2. Classify by a single principle. Once you have categories, make sure that they fit into the same organizing principle.
3. Support equally each category with examples.

The definition of classifying is categorizing something or someone into a certain group or system based on certain characteristics. An example of classifying is assigning plants or animals into a kingdom and species. An example of classifying is designating some papers as “Secret” or “Confidential.”
