How to write the content of the junior high school essay in the English speech competitionWriting an essay for a junior high school English speech competition could start from the following aspects:
** 1. In terms of structure **
1. ** Beginning **
- To get the audience's attention, you could use an interesting story, a thought-provoking sentence, or a question. For example, if the topic of the speech was about environmental protection, you could start it with: "Have you ever imagined a world without clean water or fresh air?" Have you ever imagined a world without clean water or fresh air?
- Be clear about the topic of your speech and tell the audience what you want to say. For example,"Today, I'm going to talk about the importance of environmental protection." Today, I'm going to talk about the importance of environmental protection.
2. ** Host **
- state one's views or events in an organized manner. If it was a discussion topic, such as the importance of environmental protection, you could list a few sub-arguments, such as "First, environmental protection is crucial for our own health." (First of all, environmental protection is very important to our own health.)“Secondly, it benefits the future generations.”(Secondly, it benefits future generations.) Wait. Each argument had to be supported by specific examples or data. If it was a narrative, it had to be told according to the sequence of events, including the cause, process, and outcome of the event.
- Keep it logical and use some connecting words, such as "and","but","however","more","therefore", etc. For example,"We all want to live in a beautiful world, but we are constantly polluting it. However, we can still take actions to change the situation." We all want to live in a beautiful world, but we keep polluting it. However, we can still take action to change the situation.)
3. ** Ending **
- He summarized the main content of the speech and emphasized the key points. For example,"In conclusion, environmental protection is not only a responsibility but also a necessity for all of us." In short, environmental protection is not only a responsibility but also a necessity for all of us.
- Ending the speech in a forceful way could be an appeal, such as "Let's take action right now to protect our environment!" Let's take action to protect the environment now! Or a vision, such as "I believe that with our joint efforts, our earth will become a more beautiful place in the future." I believe that through our joint efforts, our earth will become a more beautiful place in the future.
** 2. Language **
1. ** Words **
- Try to use accurate and rich vocabulary. Try to avoid repeating simple words. If you often use "good", you can change it to "excellent","wonderful","magnificent", etc. according to the context.
- Accumulate some professional vocabulary related to the topic of the speech, such as "pollution","recycling","sustainable development", etc. under the theme of environmental protection.
2. ** Sentence Patterns **
- In addition to simple sentences, some compound sentences can be used appropriately, such as attributive clauses (I like the park which has a lot of trees. I like the park with a lot of trees.) When we protect the environment, we are protecting ourselves. and so on to increase the complexity of the sentence.
- You can use some fixed sentence structures to increase literary grace, such as "It is + adj.+ for sb. to do something." it's Not only good for someone to do something but also...”(Not only…but also…) At the same time, you can also use a negative word plus a 'without' construct (as in I can't succeed without your help.) This kind of more advanced sentence structure made the essay more outstanding.
3. ** Avoiding mistakes **
- Pay attention to the correct grammar, including the agreement of subject and verb, correct tenses, etc. For example,"He likes reading books." (Not 'He likes reading books'.) "I went to the park yesterday." (Not "I go to the park yesterday")
- Pay attention to the correct spellings and check them carefully after writing.
