Who knows how to write a speech for an impromptu lecture?

As the deputy squadron leader, I have the obligation to explain the harm of picky eating. Picky eating refers to the bad habit of eating only a few kinds of food, such as only liking fish and meat, but not vegetables

I found that my classmates were picky eaters in the cafeteria, and as the deputy squadron leader, I had the obligation to explain the harm of picky eating to everyone. Picky eating refers to the bad habit of eating only a few kinds of food, such as only liking fish and meat, but not vegetablesPicky eating is reflected in eating only some of your favorite foods and rejecting others when eating.

Picky eating and picky eating have become a common problem among many children today, and they are also one of the reasons for the deficiency of certain nutrients in children. For example, some people don't like to eat vegetables, fruits, or meat, which can lead to iron deficiency anemia. Because although there is no shortage of iron in their diet, iron needs to be combined with vitamin C and the cystine broken down in meat to become soluble before it can be easily absorbed.

Therefore, not eating vegetables and fruits, insufficient vitamin C intake, naturally affects iron absorption.

Another time, I found out a good friend of mine, who is a typical picky eater. She doesn't like to eat vegetables the most, even the vegetables that her mother fried deliciously, and she refused to move her chopsticks. Her favorite food is McDonald's, and she also argues that there is no lettuce in the burger?

Later, the corners of her mouth often bleed, her hair became dry, and she finally couldn't concentrate in class, and her academic performance declined. When I went to the hospital for an examination, the doctor said: It was caused by an extreme lack of vitamins.

The doctor also patiently told her that vegetables contain a lot of vitamins A, B, and C. Lack of vitamin A will cause symptoms of dry hair and memory loss; Lack of vitamin B can lead to cracked corners of the mouth, red and swollen tongue, and depressed mood. Vitamin C deficiency can cause even more damage and affect children's growth and development. People need many different nutrients in a day, and these nutrients are contained in a variety of different foods.

So we can't just prefer one kind of food, eat a little bit of everything, so that the nutrition in the body can be balanced.

The formation of picky eating habits in children and adolescents is mainly related to the eating habits of parents and people around them, and is also related to the psychological impression of likes and dislikes left by people's daily comments on the high and low level of food. When people comment or choose food one-sidedly based on their own preferences, and ignore the impact of nutrients in food on the health of children and adolescents, children and adolescents often unconsciously develop the habit of picky eating and picky eating. Therefore, to prevent picky eating and picky eating, we should first start with parents, that is, parents themselves should not be picky eaters and picky eaters first, pay equal attention to teaching by example and words, and teach by example is more important than words.

In order to play the role of teaching by example, even if it is food that parents usually don't like to eat, they should take the lead in eating it and train their children to eat it. When children and teenagers have formed the habit of picky eating, they should listen to the teachings of parents and teachers to get rid of this bad habit.

There are already a lot of them that you can search for.

What are the characteristics of impromptu speeches:

First of all, find the topic you want to express.

After finding the topic, learn to quickly find an argument in the topic of the three key points of the impromptu speech.

It is to determine the structure of the speech, and there are many framework patterns.

What are the modes of impromptu speech:

Straight to the point, also known as pyramid, the method is: first highlight the theme, and then make a more detailed argument and analysis of the topic.

The inverted pyramid method is as follows: first give an example 123, summarize a main point through the case, then talk about the reason, and conduct argumentation and analysis.

Extemporaneous speech is also called impromptu speech.

It is a way of verbal expression that the expressor has not prepared in advance, and the presence is due to the time, events, scenes, and circumstances.

Relatively speaking, the verbal expressions in life are mostly improvised.

Extemporaneous speech is a kind of oral communication activity that does not rely on the text to express the meaning under the inducement of a specific situation and subject, spontaneously or immediately in public. The speaker did not prepare in advance, but spoke as he thought, and felt it.

There are two types of impromptu speech contests. One is to give the speaker a larger range of content and a period of preparation time before the competition, and then draw a speech in the competition. The other is that there is no scope of content, and the lecture is just drawn after the start of the speech, and the speech starts after a short preparation.

The former shows the characteristics of ambiguity, and the latter shows the characteristics of presence.

Extemporaneous speech refers to a speech in which the speaker thinks about and delivers a speech on the spot without prior or insufficient preparation, depending on the situation or situation on the spot. Extemporaneous presentations usually require the speaker to be quick to react, flexible and think deeply, as well as good language organization and presentation skills.

Impromptu speech is characterized by the speaker giving a speech without any prior preparation, so the content and structure of the impromptu speech need to be quickly conceived and adjusted according to the live situation and the audience's response. This requires the speaker to have a wealth of experience and a solid knowledge base, to be able to use a variety of language skills, and to be able to think deeply and coherently in a short period of time.

Extemporaneous speeches are difficult and require speakers to have high language organization and presentation skills, as well as the ability to react quickly and be flexible. Therefore, before the speech, the speaker can do some preparation as much as possible, such as understanding the background and needs of the audience, possible situations and problems, etc., so as to better cope with the situation on the spot.

Speech at the Copenhagen Conference.

Dear leaders and teachers: Hello everyone! It is a great honor for me to be here today, and I would like to introduce myself as an ordinary primary school student from Liaoning Province, China, and the topic of my speech today is "Protecting the Environment, Caring for the Homeland".

Protecting the environment and caring for the homeland" has become a very hot topic, people are clamoring to protect the environment every day, but how many people have really done it? People are not aware of the seriousness of the problem of the destruction of nature! If this continues, sooner or later the earth will be destroyed in our hands!

Do you not think that you are selfish when you think only about gold and silver treasures for yourself, and not for the sake of future generations? Can you bear to watch life after life be threatened, or even destroyed? How many innocent lives were devoured in Japan**, Tangshan**, the typhoon in Myanmar, and the tsunami in Indonesia?

And what is the root cause? It's about people's reluctance to destroy nature. Nature benefits mankind, and human beings must be in harmony with nature.

Now that the world has warmed and deserts are gradually increasing, is it not a serious problem for all parts of the country to face drought and disaster? Now that the earth has begun to get angry, humans, are you still awake? If this continues, sooner or later, the earth will be destroyed in our hands, and then 2012 will no longer be a legend that the year 2012 is the end of the world.

Let's work together to protect the earth, plant more trees, contribute to the protection of the environment, and make 2012 forever a legend!
