How to find the topic sentence

A paragraph consists of topic sentence, supporting sentences and concluding sentences. Those three kinds of sentences usually develop the writer's main idea, opinion or feeling about something. Every good paragraph has a topic sentence, which clearly states the topic and the controlling idea.

There are three important points to remember about a topic sentence.
1. A topic sentence is a complete sentence that is contains a subject, a verb and (usually) a complement.
2. A topic sentence contains both a topic and a controlling idea. It names the topic and then limits the topic to a specific area to be discussed in the space of a single paragraph.
3. A topic sentence is the most general statement in the paragraph.


A topic sentence is the most important sentence in a paragraph. It briefly indicates what the paragraph is going to discuss. The topic sentence maybe the first and last sentence of the paragraph.

MOBILE PHONE
Mobile phone can waste our money if we cannot control to buy credits. It's also harmful for our health, especially when we use the phone too close to our ear. Some mobile phones give the owners the easiest way to access internet. Some owners use their phones to do bad things, such as related to pornography and hijacking. It is wise if we can control the use of mobile phone as a communication tool.


SYNONYMS
Synonyms, word that have the same basic meaning, do not always have the same emotional meaning. For example, the word "stingy" and "frugal" both mean "careful with money". However, to call a person "stingy" is an insult, while the word "frugal" has a much move positive connotation1. Similarly, a person wants to be slender but not skinny, and aggressive but not pushy. Therefore, you should be careful in choosing words because many so -called synonyms are not really synonyms at all.
