Anonymous users2024-02-04Hello, glad to answer for you :
Putting out fires has always been a dangerous job. Work has become more dangerous in recent years. This is because the change in architecture over the past 30 years has led to more and more popularity, and even more unavoidable.
Today's building materials use many moresynthetic than they were built 30 years ago. Therefore, when they catch fire, burn at a higher temperature and release more energy than they do older. In addition, most modern buildings are very well insulated.
This means that when they catch fire, they think the hottest heat. Thermal fires pose a particularly dangerous situation for firefighters. The fire itself is dangerous, of course, but more of a problem is a fire caused by superheated gases.
These terms "extreme fire behavior" are used to describe firefighters who are quick to live, life-threatening events at the scene of a fire. They include flashovers. The temperature increases greatly in one area of some materials burned at once.
They also include backdrafts, which cause a fireball in the oxygen rush zone. The most dangerous effect of burning is that it can actually be in all the oxygen, room where firefighters work. Finally, there is gas**.
These occur in extreme heat so that the gas spreads rapidly. American firefighters work hard to combat the dangers of modern firefighting. Unfortunately, the mortality rate remains almost constant over the past 30 years.
This is a poor performance compared to Sweden and the United Kingdom. The two countries reduced the mortality rate between firefighters in half the same period. Why did the British and Swedes have greater success in protecting firefighters?
Some in the fire service community believe that this is because the two countries use a procedure called "three-dimensional fire extinguishing." "Now, most U.S. fire companies will stick to a firefighting strategy and believe that 3D technology can't be effective. Proponents argue that its technology greatly reduces the likelihood of an extreme fire act.
In 2002, the fire system of Gresham, Oregon became the first in the United States to accept three-dimensional fire protection technology. The battalion commander of the company, Ed Hartin, has become a supporter of the program, conducts training and writes a book on the subject. Perhaps this hinders its cost in the United States.

The general English oral test of the high school examination is the national public English level 2 oral test, which is very simple. Yes, some majors will require an English oral test, but very few, if you are worried, take the national public English level 2 oral test I said, it can cope with those majors that require oral test scores, but I personally don't think it's necessary, I took the test (Hunan) when I was in high school, and I still passed it with a full score. 5 out of 5. >>>More
To give you two suggestions, 1, you must have an environment, that is to say, speaking is inseparable from the environment, a good environment for you to immerse yourself in it, than you take some repeaters, or this oral trick is much better! 2. You must have the opportunity to communicate on the basis of the environment, cultivate your fundamental feelings and make you impulsive, and communication is to practice! Two are indispensable, I don't think this thing is good, you can consider the "human-computer dialogue" learning mode, very good, both aspects are all included.
