Candidates who have done many questions will find that many questions are unchanged, or even just changed a few names and information, but the essential methods are exactly the same. What do we call this topic? Model problem. This article helps you summarize? You're half right? Let's take a look at this model problem ~
1. Problem characteristics
Topics and information need to be matched or sorted, and clearly stated in the question? Everyone was only half right? .
2. Traditional methods
Substitution method: if the option is true, substitute it into the stem for verification. What if it doesn't match? Everyone guessed half right? That is, you need to rule out the wrong answer. If it's substitution, everyone agrees? You're half right? Is the correct answer, elected.
Method of substitution is familiar to everyone. It is simple to operate, but it takes a lot of time and is circuitous. This paper focuses on the convenience and speed of quick solution skills, look down ~
3. Quick solution skills
? If you guess half right and make assumptions, then half will be false? Is this a quick solution? You're half right? A quick way to answer questions. What do you mean? First of all? You're half right? This is the kind of problem we are talking about. For this kind of problem, we? Make assumptions? , for? Split in two? That is, the subject and information are split into two sentences, which we assume to be true, such as? ①A is A and B is B; ②A is B and C is A; 3 a is c and b is a? Of these three sentences, the first half of ①? A is a? Is split into? A is b and c is a? , suppose? A is a? Is it true?/You don't say. A is b and c is a? Both sentences are false. What else? Everyone guessed half right? Conflict, so the first half of the sentence must be false, then the second half must be true, that is, to determine the information, start with determining the information, and eliminate it while doing it.
Here, in order to help you understand, we made a hypothesis for you, but in doing the problem, we directly asked? Split in two? That sentence is false, isn't it? Split in two must be fake? , so find out the definite information and go to the option to exclude it.
In addition, after summarizing the real questions, it is found that the vast majority? You're half right? The topic? Split in two? That sentence appears in the first half of the first sentence, so we can give priority to finding out whether this sentence is split. Just say that you don't practice fake tricks, try this method from the real question ~
Example 1 three people, A, B and C, choose different occupations after graduation from university: teacher, lawyer and engineer. Other students made the following guesses:
Xiao Li: A is an engineer and B is a teacher.
Xiao Wang: A is a teacher and C is an engineer.
Xiao Fang: A is a lawyer and B is an engineer.
It was later confirmed that Xiao Li, Xiao Wang and Xiao Fang were only half right. So, what are the occupations of A, B and C respectively?
A. A is a teacher, B is a lawyer and C is an engineer.
B.A is an engineer, B is a lawyer and C is a teacher.
C. A is a lawyer, B is an engineer and C is a teacher.
D. A is a lawyer, B is a teacher and C is an engineer.
Answer d
The analysis first determines the question type, which is what the question says? Only half right? This is a model problem, which can be solved by substitution, but we use what we have learned? If you guess half right and make assumptions, then half will be false? It will be faster. ? Split in two? Usually the first half of the first sentence: the one that Xiao Li said? A is an engineer? Why did Xiao Wang say it? A is a teacher and C is an engineer? If it is split into two sentences, then the first half of Xiao Li must be false, that is? B is a teacher? This must be true. Find certain information and do it while eliminating it. B is a teacher? There is only option d, so choose option d.
Is this spike technique faster than your original four options? After everyone understands, try to solve the following problems with this method!
Last year, a town sent three university student village officials, A, B and C, to work in Hefeng Village, tuanjie village Village and Yangmei Village respectively. At first, people didn't know which of them was assigned to work in which village, but they made the following three guesses:
① A was assigned to work in Hefeng Village, and B was assigned to work in tuanjie village;
② A was assigned to work in tuanjie village, and C was assigned to work in Hefeng Village;
③ A was assigned to work in Yangmei Village, and B was assigned to work in Hefeng Village.
It turned out that all three guesses were only half right. From this, () can be deduced.
A. A was assigned to work in Hefeng Village, B to work in tuanjie village and C to work in Yangmei Village.
Party A was assigned to work in tuanjie village, Party B was assigned to work in Hefeng Village and Party C was assigned to work in Yangmei Village.
C.a was assigned to work in Yangmei Village, B to work in Hefeng Village and C to work in tuanjie village.
D A was assigned to work in Yangmei Village, B was assigned to work in tuanjie village, and C was assigned to work in Hefeng Village.
Answer d
The analysis first determines the question type, which is what the question says? Only half right? , which belongs to the mode problem. Split in two? Generally, it is the first half of the first sentence: ①? A was assigned to work in Hefeng village? At 2? A was assigned to work in tuanjie village, and C was assigned to work in Hefeng Village? Is split into two sentences, then the first half of the sentence must be false, that is? B was assigned to work in tuanjie village? It must be true, the option says? B was assigned to work in tuanjie village? There are options a and d, and continue to reason. B To tuanjie village? Then the first half of the sentence is false and the second half must be true, that is? C to Hefeng village? , only the d option meets, so choose the d option.

There are five cabinets in the archives room, which contain materials from five colleges, namely, the College of Education, the College of Physical Education, the College of Humanities, the College of Management and the College of Information. Now five students, A, B, C, D and E, will guess the corresponding relationship between these five cabinets and five colleges:
A: The second cabinet belongs to the Institute of Education and the third cabinet belongs to the Institute of Physical Education.
B: The second cabinet belongs to the School of Humanities and the fourth cabinet belongs to the School of Management.
C: The first cabinet belongs to the School of Management and the fifth cabinet belongs to the School of Information.
D: The third cabinet belongs to the College of Humanities and the fourth cabinet belongs to the College of Information.
E: The second cabinet belongs to the Institute of Physical Education and the fifth cabinet belongs to the Institute of Education.
When I opened the cupboard, I found that everyone was only half right, and one person in each cupboard was right. From this, it can be concluded that:
A. The first cupboard contains the materials of the School of Humanities.
B.the second cupboard contains the information of the Institute of Education.
C. in the third cabinet is the information of the school of management.
D. the fourth cabinet contains information from the school of information.
Answer d
What does the problem analysis say? Only half right? The first half of the first sentence is mainly: a said? The second cabinet belongs to the Institute of Education? Right here at e:? The second cabinet belongs to the Institute of Physical Education, and the fifth cabinet belongs to the Institute of Education? Is split into two sentences, then the first half of A must be false, that is? The third cabinet belongs to the Institute of Physical Education? Must be true, excluding the c option. Follow the trail and continue to reason. The third cabinet is the Institute of Physical Education? What about the third cabinet? Does the Third Cabinet belong to the College of Humanities? False, the second half sentence must be true, that is? Does the Fourth Cabinet belong to the School of Information? , only the d option meets, so choose the d option.
A Rubik's cube has six faces. When all six surfaces are restored, the colors are red, blue, yellow, white, green and orange. At the scene of a variety show, there are six Rubik's cubes, each of which has only one side restored, and the color of the restored side of each Rubik's cube is different. The host put six Rubik's cubes into six opaque boxes numbered 1 ~ 6, and opened the box numbered 1, which contained the Rubik's cubes with blue restored faces. Then the host asked five guests, Liu, Zhao, Tang, Zheng and Yang, to guess the colors of the Rubik's Cube in other boxes. The five guests made the following guesses:
Liu: The Rubik's cube recycling surface of box 3 is orange, and the Rubik's cube recycling surface of box 4 is yellow.
Zhao: The Rubik's Cube in Box 3 is green, and the Rubik's Cube in Box 5 is red.
Don: The Rubik's Cube in Box 2 is red, and the Rubik's Cube in Box 6 is white.
Zheng: The Rubik's Cube in Box 4 is green, and the Rubik's Cube in Box 5 is white.
Yang: The cube recycling surface of box 3 is yellow, and the cube recycling surface of box 6 is orange.
Then the host opened the boxes one by one and found that each guest only guessed the color of the Rubik's cube recovery surface in one box, and one guest in each box guessed it correctly.
It can be inferred that:
A. The Rubik's Cube recycling surface in Box 2 is green.
B the recycling surface of the Rubik's cube in box 4 is not yellow.
C the recycling surface of the Rubik's cube in box 5 is white.
D the Rubik's cube recycling surface in box 6 is red.
Answer d
What does the problem analysis say? Only half right? The first half of the sentence is dominant; Liu said? Box 3' s Rubik's Cube is orange? , just in Yang:? The cube recovery surface of box 3 is yellow, and the cube recovery surface of box 6 is orange? Is split into two sentences, then the first half of Liu's sentence must be false, then? Is the Rubik's Cube recycling surface of Box 4 yellow? Must be true, rule out option B, and continue reasoning by following the trace. Box 4 is yellow? So Zheng: It involves Box 4? Is the Rubik's Cube recycling surface of Box 4 green? Is that fake? Is the Rubik's Cube recycling surface of Box 5 white? If true, only option C meets the requirements, so choose option C..
These questions are all with you, and the method is very easy to use and fast. Let's sum it up.
4. Experience summary
? If you guess half right and make assumptions, then half will be false? After mastering the formula, the first sentence of 90% real questions is usually wrong first and then right, that is, does the first half of the first sentence take precedence? Split in two? , have you found it? Split in two? After that sentence, get a definite message, follow the clue and eliminate it at the same time.
There are still many simulation problems in analytical reasoning. You must be good at summarizing when you brush the questions. It is not difficult to get the right answer, but our goal is to be quick and accurate. The time saved here may make you do more problems and become a small advantage. In short, summarize the simulation questions and let you be one step ahead!
