Once you decide to choose a topic to write an effective paragraph, the first key to writing is to write a good topic sentence. The topic sentence does two things: it tells the reader what the topic of the paragraph is, and it says something about that topic. What the topic sentence says about the topic is called the controlling idea; it is the point of the paragraph, and every other sentence in the paragraph must be related to this point.
The topic sentence should be the first sentence in the paragraph unless there is some special reason for placing it some where else. When the topic sentence is the first sentence of the paragraph, the reader immediately knows what you intend to discuss. In addition, you have the topic sentence to refer to as you make each of the other sentences in the paragraph, so that you can be sure that each of those sentences refers to your subject and to your controlling idea. Sometimes experienced writers put the topic sentence at the end
A. is about sentence writing
B. is about word spelling
C. is "What is an Effective Sentence"
D. is "What Makes a Good Paragraph"
