There are three types of sentences in a paragraph: topic sentences, supporting sentences, and concluding sentences. An effective topic sentence is a complete sentence. Supporting sentences give the reader more information about the topic sentence. The last sentence in a paragraph is your concluding sentence.
There are three types of sentences in a paragraph:
- topic sentences
- supporting sentences
- concluding sentences.
A topic sentence is usually the first sentence of a paragraph. It states the main idea of the paragraph. The topic sentence will contain a topic and an idea about the topic, called a "controlling idea." The controlling idea controls, or limits, the amount of information you will write about the topic in your paragraph.
An effective topic sentence—
- is a complete sentence.
- is usually at the beginning of a body paragraph.
- clearly supports the thesis statement (topic of essay + one controlling idea).
- does not announce the topic (e.g., “I’m going to talk about the ELC.”).
- should not be too general (e.g., “The ELC is a great place.”).
- should not be too specific (e.g., “Studying at the ELC costs people who study full-time a lot of money every semester and even more if they are not residents.”).
This is an example of a good topic sentence:
The ELC is a great place to learn English.
“The ELC” is the topic of the paragraph. There are many things that can be said about the ELC: the location, the cost, the curriculum, the teachers, the students, the tutors, the resources, etc. However, the controlling idea limits and gives focus to the paragraph. “...is a great place to learn English” is the controlling idea of the paragraph.
Your paragraph needs to explain why or how your topic sentence is true. The sentences that explain your topic sentence are called supporting sentences. You can have many types of supporting sentences. Supporting sentences can give examples, explanations, details, descriptions, facts, reasons, etc.
Consider the topic sentence from before: The ELC is a great place to learn English.
These are some examples of supporting sentences that could be used to develop a body paragraph about the ELC being a great place to learn English.
- Explain: The focus of the ELC is to help each student progress in their goals. (Explains why the ELC is a great place to learn English.)
- Describe: The ELC has level-specific goals for each class that give focus and purpose to every lesson. (Describes a part of the curriculum for the school that makes it a great place to learn English.)
- Give reasons: The ELC supports and motivates its students within the classroom as well as outside of it. (Gives a reason for why the ELC is a great place to learn English.)
- Give facts: There are many activities offered to students for extra English practice. (Gives a fact about the school that shows the ELC is a great place to learn English.)
- Give examples: Some of the important resources available to students include tutors, computers, and a large library of English books. (Gives an example of the resources that make the ELC a great place to learn English.)
The last sentence in a paragraph is your concluding sentence. Your concluding sentence should end your paragraph logically. Concluding sentences can restate the main idea of your paragraph, state an opinion, make a prediction, give advice, etc. New ideas should not be presented in your concluding sentence.
Again, consider the example topic sentence from before:
The ELC is a great place to learn English.
Concluding sentences . . .
- Restate the main idea: There is a wonderful environment for learning English at the ELC.
- State an opinion: The ELC is the best school for studying English.
- Make a prediction: If you study at the ELC, your English will improve.
- Give advice: You should come to the ELC to learn English, too!

______________________________________________________________________. First, a good teacher needs to be patient. There are many skills that take a long time to learn and students will make many mistakes during the learning process. Students will also have a lot of questions. A good teacher will be patient when the students make mistakes and ask questions because she knows that it takes time to learn new things. Another quality of a good teacher is that they are passionate. A good teacher is excited about teaching and can help the students be excited about learning. During a difficult learning process, students need a passionate teacher so they want to continue studying. Both of these qualities are important for a teacher to have.

We need courage, for example, when there is a war or other bad things. Courage is when people risk their lives to help and save people in danger. When we have an accident or an illness, overcoming the physical or mental difficulties takes courage. It takes courage to find joy and hope in life. When we are tired, we need courage to continue, such as when an athlete continues to the finish line in a marathon. Abbe Pierre said, “The biggest failure is not having the courage to dare.” I agree with this. In our lives, we need to have courage in difficult things.
______________________________________________________________________. First, many people turn to YouTube when they want to know how to do something new.

Another reason people watch YouTube videos is to be entertained. There are many YouTube channels that specialize in telling stories, making music, or showcasing unique talents. These entertaining YouTube videos are shared with friends or posted to social media because they are funny or interesting. These are just two of the many reasons why people like to spend time on YouTube.
