Multiple communication methods?

There are many modern modes of transportation. What are their characteristics?

Diversification is wrong. Remember that there are only five modes of transportation: air, water, rail, road and pipeline.

Aviation: fast speed, high freight rate, easy to be affected by the weather and good safety.

Waterway: large quantity and low price (the turnover of goods ranks first among the five)

Railway: fast, but controlled by the state, not flexible enough, perfect network.

Highway: the only mode of transportation that can realize door-to-door transportation, can adapt to harsh environment and has poor safety.

Pipeline: at present, it can only be used to transport fluid raw materials, and it is buried underground, which is not easily affected by the outside world.

What are the first three main forms of communication?

Writing methods of news communication

(1) communication type

When talking about communication writing, we should first know the types of communication. According to the custom, people divide communication into four types: communication between people, communication between things, communication between work and style. In addition, there are sketches, profiles, stories, interview notes, letters from reporters, etc. Most of them can be combined into the above four corresponding communication types.

(B) the characteristics of communication

Communication is a kind of news reporting genre that uses various expressions to report real and objective things in depth and in detail. It is a kind of news, like news, reporting facts to readers.

Communication has the following characteristics: 1. Communication is a detailed and in-depth report. When news figures, news events and situations are reported by communication, it is generally necessary to explain the ins and outs of the matter and the development process, and make some specific descriptions of some important links and scenes. Compared with news reports, communication reports are more detailed, in-depth and specific. 2. Communication is a kind of news style, which has many manifestations. The common expressions of communication are narration, description, discussion and lyricism. These expressions can be used flexibly according to the specific content of communication. Writing people's notes vividly and moving people with emotion is a feature of communication and expression. 3. The communication report is vivid and infectious. While transmitting information, communication often uses narrative, description, discussion, lyric and other expressions flexibly according to specific content, which makes communication appear flexible, vivid and vivid, and has certain appeal. In addition, communication, like news, must have various basic elements. However, communication is different from news. In terms of transmission time, it has more relaxed requirements than news; In content, it has a depth and breadth that news can't reach, and it has background material that simple news messages don't have. So, in a sense, it can be a historical record, which is happening now. After a few years, people can reread these newsletters and relive the historical fragments of that year.

(3) Character communication

Character communication is the communication with reporting characters as the main content. This kind of communication is the most common. In particular, some newsletters that report the advanced deeds and thoughts of advanced figures often occupy the main pages of newspapers and periodicals. The characters reported in people's communication are specific and often have high news value. It can be positive or negative characters, but the positive characters are the main ones. The basic requirements and methods of written communication are as follows:

1, to reflect the characteristics of today's times, people's communication is different from biography. People's communication is news, and the people it reports should have a sense of the times and reflect the spirit and outlook of the times. Therefore, in writing, on the one hand, we should try our best to dig out what best reflects the characteristics of the times in the characters; On the other hand, we should grasp the problems that people are generally concerned about and urgently need to solve in real life, choose typical examples and report typical examples, so that communication has a strong flavor of the times.

2. To write the characteristics of characters, the key to writing character communication is to write people, and how to write characters vividly is an important task of character communication. To write the characters vividly, we must first grasp the characteristics of the characters. Generally speaking, the more distinctive the characteristics of a character, the more distinctive the image of the character. When writing the characteristics of characters, we must carefully select typical plots and details. Without typical material, you can't write a living person anyway.

3. Representing characters by behavior is a common expression in character communication writing.

There are two ways to write character communication. One is a comprehensive report on a character's life, or a certain stage or aspect. This kind of character communication, character activities and events have a long development time span, more materials are used, and the length is generally longer. Another way of writing is not to report the characters comprehensively, but to grasp a specific situation and write the spirit and characteristics of the characters with a few simple strokes; Or do some side reports on the spirit and characteristics of the characters. This kind of communication is also called "sketch" or "sidelights".

(4) Event communication

Event communication, as its name implies, is a type of communication that reports major or abnormal events.

The event newsletter describes recent events that have attracted widespread attention. Therefore, event communication mainly reports events, introduces the ins and outs of events and their development process, and often has a beginning and an end, a plot and details. Even if the space is short, we should explain the event clearly so that readers can have a relatively complete and clear impression of the event after reading it.
