How do topic sentence supporting sentences concluding sentences and main idea contribute to the development of a paragraph Brainly?

Developing a Topic Sentence

Pick up any newspaper or magazine and read the first sentence of an article. Are you fairly confident that you know what the rest of the article is about? If so, you have likely read the topic sentence. An effective topic sentence combines a main idea with the writer’s personal attitude or opinion. It serves to orient the reader and provides an indication of what will follow in the rest of the paragraph. Read the following example.

Creating a national set of standards for math and English education will improve student learning in many states.

This topic sentence declares a favorable position for standardizing math and English education. After reading this sentence, a reader might reasonably expect the writer to provide supporting details and facts as to why standardizing math and English education might improve student learning in many states. If the purpose of the essay is actually to evaluate education in only one particular state, or to discuss math or English education specifically, then the topic sentence is misleading.

Tip

When writing a draft of an essay, allow a friend or colleague to read the opening line of your first paragraph. Ask your reader to predict what your paper will be about. If he or she is unable to guess your topic accurately, you should consider revising your topic sentence so that it clearly defines your purpose in writing.

Main Idea versus Controlling Idea

Topic sentences contain both a main idea [the subject, or topic that the writer is discussing] and a controlling idea [the writer’s specific stance on that subject]. Just as a thesis statement includes an idea that controls a document’s focus [as you will read about in Chapter 8 “The Writing Process: How Do I Begin?”], a topic sentence must also contain a controlling idea to direct the paragraph. Different writers may use the same main idea but can steer their paragraph in a number of different directions according to their stance on the subject. Read the following examples.

• Marijuana is a destructive influence on teens and causes long-term brain damage.
• The antinausea properties in marijuana are a lifeline for many cancer patients.
• Legalizing marijuana would create a higher demand for Class A and Class B drugs.

Although the main idea—marijuana—is the same in all three topic sentences, the controlling idea differs depending on the writer’s viewpoint.
