In the line test, mathematical operation has always been a big problem for the majority of candidates, with great difficulty and tight time.
At the same time, this part of the math operation that is the easiest for candidates to give up is also very skillful, and a small number of questions can really "kill"! It is easy to score. The following Chinese public education experts will tell candidates about these methods:
Example: 1, 20 people can finish a job in 15 days. Now working for three days, five people are transferred to plant trees, and the rest continue to finish the rest of the work. How many days will it take to finish the work?
16， 17， 18， 19
General solution. The first type: special value method. If the workload per person per day is 1, then the total workload is 20* 15* 1=300, the first completed quantity is =20*3* 1=60, and the remaining 300-60=240 needs 240//.
The second type: proportional method. The efficiency ratio before and after 3 days =20: 15=4:3, then the time ratio =3:4, then the later workload is 12 days according to the original efficiency, that is, 3 copies correspond to 12 days, then 4 copies correspond to 16 days, and * * is counted as/
"second kill method": A+3 = D. Option A is a normal calculation result, but it is not the desired result. It is easy for candidates and friends to choose the wrong A in the examination room (A is actually a trap set by the questioner), and D is the really wanted "How many days does it take to complete this work?" .
Example 2: 99 apples are divided into two kinds of packaging boxes, large packaging box 12 and small packaging box 5. * * * More than a dozen boxes have just been packed. What's the difference between the two boxes?
A.3 B.4 C.7 D. 13
Conventional solution: equation method. There are x large boxes and y small boxes. According to the meaning, 12x+5y=99. According to parity, 5y must be odd, that is, Y is odd, so the mantissa of 5y can only be 5, the mantissa of 12x is 4, and x = 2 or 7. When x=2, y= 15, which meets the meaning of the question, so the difference between the two boxes is 15-2= 13. (When x=7 and y=3, x+y= 10 does not meet the requirement of "* * * used more than ten boxes". )
"second kill method": a+c = 10, c-a = B. But in the stem, "* * * used more than a dozen boxes", so A, B and C are not correct answers, so choose D directly.
There were 830 employees in a company last year. This year, male employees decreased by 6%, female employees increased by 5%, and the total number of employees increased by 3. How many male employees are there this year?
329 B.350 C.37 1 D.504
"second kill method": A+D=833. There should be a certain number of male employees and error-prone female employees in the options. Men decreased by 6% and women increased by 5%, but the overall number increased, indicating that the base of female employees is relatively large. The answer is directly a.
Through the analysis of the above three examples, I believe that everyone can also see the magical problem-solving effect brought by the analysis options. Finally, Chinese public education experts will help you make a summary. What kind of questions can you use this method to make bold questions in the examination room in the future to achieve the effect of "seconds kill"? To sum up: the addition and subtraction relationship between options is related to the stem information.
2. Provincial civil servants judge how to do it with common sense, and choose all or choose blindly.
First, the complete review of common sense judgment from beginning to end involves a wide range of knowledge points. If you don't know where to start, you may give up reviewing.
Review of common sense judgment should pay attention to the following points. First of all, on the basis of previous knowledge accumulation, it is suggested that candidates use their usual time to read all the subjects in the common sense part and do corresponding special exercises without asking too much.
Secondly, real questions and simulation training. Finally, when the exam is near, read the information again to review the old and learn the new.
Second, the common sense judgment of the preparation method of skillfully taking scores is partly because of the complexity of knowledge, so we must master the correct preparation and review methods for specific content, so that we can get twice the result with half the effort when reviewing. Pay more attention to national conditions and social conditions.
The so-called national conditions and social conditions refer to China's geography, history, national character and other contents, as well as the country's major policies. Candidates should focus on reviewing this part. Master the overall context of each subject.
The content of common sense judgment test covers politics, economy, law, history and many other aspects, and there are many knowledge points. Candidates should not scratch their eyebrows when doing this part of the review. It is suggested that candidates should grasp the content of each subject as a whole when reviewing, and the summary review can better grasp the essence of each subject, so as not to lose big because of small. For example, the economic part: macroeconomics: fiscal policy, monetary policy, income distribution policy, consumption policy, etc. Such as human history: ancient history of China, modern history (Opium War, Westernization Movement, Reform and Reform, Taiping Heavenly Kingdom, Xinhai Revolution, etc. ), and world history.
Humanistic literature: ancient literature, modern and contemporary literature and world literature. Give and take.
There are relatively many types of questions in the test, and the answering time is relatively short, while the common sense judgment part covers a wide range. Candidates must master the speed of answering questions, give up the content that has not been reviewed, and spend precious answering time on more confident topics. Third, calm and calm preparation mentality Candidates should believe that through long-term systematic review, their knowledge level will definitely improve and their mastery of knowledge points will become more and more skilled. The mentality of preparation should be adjusted, persevering and persevering.
Give yourself more positive psychological hints, believe that you are the best, and you will certainly achieve ideal results in the exam.
3. How to review the common sense part of the civil service examination?
In the part of common sense judgment, we examine a wide range of knowledge, mainly relying on the usual accumulation to be a conscientious person in life. For example, it is not enough to pay attention to current events, but it is not enough to just know when and what happened. We also need to read some review articles to understand the ins and outs of some international and domestic events, including the causes, influences and possible solutions.
To be a conscientious person in life, you can pay more attention to some common phenomena in daily life and ask why, for example, why the river freezes in the cold winter in the north and the deep water is still flowing; Why do you feel tired when you go up the mountain, but you can't wait when you go down the mountain? We should pay attention to these phenomena, and pay more attention to the reasons behind them, so as to do the right thing. There are also some professional legal knowledge, economic knowledge, historical knowledge and cultural knowledge, so you can find some books to read relatively intensively. The preparation of comprehensive knowledge should be based on the mentality of "knowing as much as possible" and accumulated in a down-to-earth manner. You can't always worry about what to do as soon as you see the topic. This kind of trouble is not only meaningless, but also makes you impetuous and has a negative impact on preparing for the exam.
Now I want to ask how to review the common sense of civil servants' exams. Many contents are crooked.
20 15 Zhejiang civil service examination:
Civil servant exam counseling: how to break it all
1, common sense
It is often said that common sense should not be prepared. There is some truth in this statement, but it is not all right. Common sense is very important in peacetime accumulation, and the effect achieved by temporary assault is not very ideal. Some common sense questions will not be prepared, but we can settle for the second best. You can prepare some political and legal questions. We can pay more attention to news and political hotspots in peacetime, because these will often become examination questions. It's a pity to lose such a score.
2. Speech comprehension
Speech can be divided into word selection and fragment reading. For the choice of words, it is inseparable from the usual accumulation, and there is nothing to say.
For fragment reading, you don't need to worry about the correct answer to each question when you do it, but you should care about how you got the answer. Since you made a mistake, you did it in the wrong way. Try to find the correct answer in another way. Under the contrast of various methods, why the former method is wrong and the latter method is right, then you can strengthen it in the later problem solving, so that over time, your problem solving accuracy will definitely improve.
3. Mathematical operations and reasoning
This is my weakest link, and my experience is nothing else. I repeatedly use methods and problem-solving skills to find the same type of problems, and I can use the same problem-solving methods. Remember to sum up after I finish. This kind of operation is boring, but it is really practical. At least in the examination room, you won't be in a hurry because you can't remember it.
4. Data analysis
The data analysis problem is the most difficult to do, but it is also the easiest to get points. After all, as long as it's not a blind calculation, I got a problem right in these calculations, unlike words and logic, and I can't be 100% sure when I choose it.
Good data analysis and calculation methods only provide you with an idea, which needs constant practice and integration into your usual calculations. Only in this way can you really use these so-called calculation skills in the examination room, otherwise, even if you learn the method of 1000, you won't need it.

5. Common sense of civil service examination
Common sense is really a headache. After passing the exam in 2009, I feel that there will be half of it, and the rest can only be fooled. However, I think this is better, at least it can free us from the legal knowledge of Big Ben and make the exam more "fair". It is estimated that 20 10 is also this model, but the specific words still depend on what the exam outline says.
It's hard to say that you can review comprehensively. If this is the case, it will not be worth the loss (I don't know exactly what it is), because this part of the score can be said to be the lowest, and it can't be opened at all. How can the average person get about half? After all, it's common sense. There is a little more left, and the gap is only one or two points (no contempt).
If you are interested, buy a copy of "Public Basic Knowledge" and common sense questions from other provinces, or look at Chinese books (poems), history books and geography books in previous middle schools. I feel that I have a lot of previous knowledge, and I didn't say anything about turning a few corners. If you have an impression, you will definitely not if you haven't studied it.
Finally, there is still a long time to study, so don't give up easily. Even half a point in the national examination may be worth thousands of dollars! Come on!
6.20 18 national civil service examination survey: "Mongolian routine" is not deep at all.
Many candidates have a feeling when doing test questions, that is, there is not enough time, and they often have no time to do it at the end, so they can only be blindfolded. Most candidates put the quantitative relationship that they are not good at last, so how can we be more accurate? Actually, it's skillful.
Tip 1: Look at the multiple by doing the problem, and choose the multiple. Example: 1 A and B bought the same number of radishes. A plans to buy 65438+2 radishes from 0 yuan, and B plans to sell 65438+3 radishes from 0 yuan. If Party A and Party B sell all the radishes at the price of five in 2 yuan, the total income of 4 yuan will be less than expected. How many radishes do they have? A.420 B. 120 C.360 D.240 Analysis shows that two people eat the same amount of radishes, so they should eat twice as much radishes as one person, and the relationship between options B and D is exactly twice, so choose D.
And b should be the number of radishes a person eats. Tip 2: See the difference between dry questions and poor questions and find the difference between options. Example 2 The labor department in a certain place rented two classrooms, A and B, to carry out practical talents training in rural areas.
Both classrooms have five rows of seats, a classroom 10, and b classroom with 9 people. Teacher Liang trained 27 times on the first day of the month, and each training was packed, with 1290 person-times in the month.
How many times has classroom A held such training this month? A.8b.10c.12d.15 Analysis: There were 27 trainings in the two classrooms that month, and the sum of options C and D was exactly 27, so the answer was one of them. If the answer is C, the total number of students in classroom A is even, and the total number of students in classroom B is odd. Tip 3: Clever use of separable features Example 3 Two police stations accept cases 160 a month, including criminal cases 17% in police station A, 20% in criminal cases in police station B, and how many non-criminal cases did police station B accept this month? The total number of cases analyzed in A. 48 b. 60 c. 72d. 96 A must be a multiple of 65,438+000, so it can only be 65,438+000. Otsuichi * * * is 60 cases, 80% is 48 cases. Choose a.
