2. Why hasn't the Common Sense Examination Pass been updated for two years?

For a civil servant, classroom teaching, videos and books are our three magic weapons to win. An experienced teacher who understands exams will help us master the skills of doing problems quickly. Video learning will help us review many times. A good book can help us lay a good foundation and save review time. Just like the common sense part of the exam, the scope of the exam is very wide, involving culture, science and technology, history, politics, law, geography, common sense and other knowledge. We will be very tired by self-study, so we need a professional book to summarize and sort it out for us. But can you imagine that a common sense test book of FB has not been updated for two years, so we can't review the updated test center, so our common sense score can be imagined.

I didn't notice it at first, but later my classmates reminded me that the knowledge points in it had not been updated for a long time. I still don't believe it. I think an institution must be rigorous and helpful to candidates. With browsing, I found that this is indeed a fact.

For example, there are some civil laws and criminal laws. In books, it is similar to undergraduate textbooks. However, some new laws are not involved and should be updated in time. If it is the old method, it is unfair to our illegal professional candidates. Fortunately, the national examination tends to focus on the new law, but this is based on the existing law, and there is no introduction to update the new law, which completely misleads our review direction. As a result, many things I read were useless and I couldn't even pass the exam.

After being reminded by classmates, I found that the same is true of technology and current politics. We can understand the relative lag of knowledge. After all, it takes time to compile a book, and it can't be updated from time to time, but it can't stay two years ago. How can I review the newly added test sites? We don't ask you to update to the latest, even if it is updated to the first half of this year. Really from the heart.

Have you considered our feelings? I admit that your courses are relatively cheap, and that's because they are online courses. We can't just deal with books. An educational enterprise, whether responsible for students or your enterprise, can't compare with big brands like Tuhua and Zhonggong to increase teaching and research, but we can't help being responsible. Recently, because of the problem of this book, I also paid attention to FB. In addition to slobbering every day, it is better to focus on products and be responsible for our students, at least worthy of the money you received and the trust we had in you.

Not much to say. If I say more, some people will say that I am a water army of other institutions. I just express my dissatisfaction and let more people who want to buy this book know. Don't waste money, stop talking and waste more time. It is fair and comfortable for people to waste their limited review time on such a book two years ago. You will know what I am talking about when you find this book. I hope that the leaders of the organization can see it and make improvements. Really don't let us do it again.

3. What are the basic common sense of exploring holes?

First of all, when you make preparations before excavation, you must make clear all the basic equipment needed for excavation. These equipment should include: lighting appliances, food, drinking water, ropes and protective equipment.

Because many places in the cave are very narrow and often have to crawl through, it is best to bring knee pads, elbow pads, gloves and safety helmet. The safety helmet can not only prevent meeting when drilling, but also prevent being injured by accidentally falling gravel. In addition, the flashlight should bring enough spare batteries and spare bulbs. The rope should be strong. You can also bring a few whistles to contact.

In addition, the flashlight should bring enough spare batteries and spare bulbs. The rope should be strong. You can also bring a few whistles to contact.

It is best to light the hole with calcium carbide lamp, because when there is no oxygen in the hole, the flame color of the calcium carbide lamp will change obviously, which can remind the hole seeker to quit in time. It is worth noting that when the calcium carbide is burned to remove the residue, there will be residual calcium carbide gas escaping, so it is necessary to prevent others' calcium carbide lamp flame from igniting the escaping gas. Therefore, when one person replaces a new calcium carbide, others have to withdraw from a certain distance (more than 5 meters), and when using the calcium carbide lamp, they still need to bring a flashlight for standby.

The biggest danger of digging a hole is getting lost. In order to prevent getting lost, the general method is to set up road signs. It is best to prepare some reflective road signs with different colors (such as the reflective plate on the fender at the rear of the bicycle) and number them, and put them in order of number. Put road signs of different colors on different branches (don't be afraid of trouble). The advantage of reflector is that it is easy to be found and can be recycled. Some people like to draw arrows on the cave walls with chalk. According to our experience, such road signs are not easy to find, and they are easy to be mixed with arrows drawn by other cave explorers, which will pollute the cave walls.

Caves generally consist of narrow passages and spacious "halls". The hall is often a place where several passages meet, and it is covered with rocks. It's easy to enter the hall from the passage, but it's difficult to find the entrance from the hall. So when you enter the spacious hall from the narrow passage, you must make a reflective road sign at the entrance.

If you have lost your way, the first thing to do is to stop immediately, don't panic and stabilize your mood. You'd better sit down and rest 10 minutes, and then find a way out. In the case of getting lost, people's feelings are often unreliable At this time, you should put aside all feelings and solve them in concrete ways. Start making road signs where you find yourself lost, and then try one direction at a time. Be patient and grope slowly. It should be reminded that caves are all eroded by groundwater. When the river washes away the cave wall, it will leave traces, from which the flow direction of the river can be judged. At this time, no matter which "tributary" you are in, you can go downstream. In fact, any professional digger doesn't make road signs. They will easily walk out of the complicated underground river according to the traces of water scouring.

It is worth noting that it is not suitable to enter the cave after several days of heavy rain and after the earthquake, because the situation in the cave is unstable and prone to landslides.
