20 17 Tianjin Selected Graduates exam information summary

In April 20 17, Tianjin recruitment announcement and public information introduction need to improve knowledge points and sort out the key points and difficulties of Selected Graduates exam. In order to help candidates better prepare for the exam, Selected Graduates. Com has compiled the problem-solving skills of Selected Graduates knowledge for everyone, and helped Selected Graduates succeed in the exam. American Indians are disappearing. Tom is an American Indian. From this, we can know that Tom is disappearing. Such a seemingly correct syllogism reasoning model often appears in the evaluation topic of possibility reasoning. Many candidates will doubt this reasoning. Tom has disappeared, and he is no longer a professor. How could he disappear? But we can't grasp the key of error in reasoning. Will it be unveiled for everyone today? Mysterious Tom? Veil.

In such a form of reasoning, embodied reasoning errors are called. Confusion between set concept and non-set concept? , what else can I call it? Four concepts? Mistake. The so-called set concept refers to the nature of the aggregate, and the individual objects that make up the aggregate do not necessarily exist, only the aggregate does; The concept of non-set, the individual objects in the set must have this attribute. First one? American Indians? Refers to the concept of set, because when we use? Is disappearing? To describe? American Indians? When refers to the reduction of the number of American Indians as a collective race, it does not want to express that every Indian is disappearing. The second one? American Indians? Tom is a special case among American Indians. Through analysis, we can know that these two are actually? American Indians? Do not refer to the same concept.

After understanding the basic differences between set concepts and non-set concepts, we can use this knowledge to determine which category the following three concepts belong to and strengthen our understanding:

Example 1: Man can conquer nature.

Dial here? People? It is the concept of set, which means that a complete human being, not a single person, can overcome the sky.

Exodus 2: Lu Xun's novels can't be read in one day.

Dial here? Lu Xun's novels? It is a set concept, which means that the whole novel written by Lu Xun can't be read in one day. It is not difficult to see that in fact, a single individual in Lu Xun's novels, such as Blessing, can be read in one day, so it does not mean a non-set concept.

Example 3: All the students have passed CET-4.

Dial here? Student? The concept of non-set means that every student has passed Band 4.

Since everyone has a deep understanding of the concepts of set and non-set, let's test it with an exercise:

Doctors have to treat many patients in the hospital. Xiao Wang is a doctor, so he has treated many patients.

A. fruits are rich in vitamins. Apples are fruits, so they are rich in vitamins.

B. The old employees are excellent, and Li Gang is a new employee, so Li Gang is not an excellent employee.

C periodical editors should not only organize the editing of manuscripts, but also write their own academic articles. Lao Zheng is the editor of a periodical, so he has written many academic articles.

All the students in this university get good grades. Xiao Zhao is a student in this university, so his academic performance is very good.

Answer a.

The way to analyze the problem is: S is P, A is S, so A is P. From the external form, the argument of item B is as follows: all S are P, A is not S, so A is not P, which is different from the argument of the problem; Item c is also different from the argument of the stem. You can write it yourself? Can't push it out? Write a lot? ; Item a and item d are consistent in form. But at the same time, the first question? Doctor? This is an established concept. Only a professional group like doctors can treat many patients. What about the second one? Doctor? Is the concept of non-setting. The first one in item a? Fruit? Is a set concept, only the whole fruit can correspond? Various vitamins? And the second one? Fruit? Is the concept of non-setting. Item d is the correct syllogism reasoning model, the first one? Student? True or false, since all students have good grades, it means that every student has good grades. What about the second one? Student? It is also a non-set concept and cannot be equated with stem.
