Whether it is a national or provincial exam or other types of exams, the hypothetical proposition of the line test is a type of question type that is commonly tested. Due to the influence of life experience and other factors, people will always judge the "sufficient conditions" and "necessary conditions" in the hypothetical proposition based on their feelings, so as to deduce the wrong inference relationship, and finally let themselves lose points in the questions that could have been easily scored. Therefore, for hypothetical propositions, if you want not to lose points, you can actually quickly judge the relationship between the question stem and the launch of options through conjunctive words, so as to improve the speed of doing questions.
For the judgment of the relationship between the introduction of our hypothetical propositions, we can divide them into three categories through different conjunctive words, each of which summarizes the mantra for everyone:
1) Forward and backward: If....So....Only....Only...; For....Definitely....Everything....All...; Want....It has to be..../…Can't do without...., there is no connection is, just, then.
2) Push back forward: only....Just...; Nope....Nope....Unless....Otherwise no....
3) The base pre-key, which is pushed out.
So, if the question appears something like: If....So....Yes, that's it...; Only....Only...; only need to push the content after "if" to the content after "then"; If the question appears such as: Only....Just...; Unless....Otherwise no.... , you need to push the content after "only" to the content after "only"; If the stem appears....Yes....The premise, foundation, and key of the case, who is the premise, foundation, and key, who is written behind the launch symbol. Let's take a look at a topic:
Example] The key to steadily improving your score on the logic test is to have a real understanding of the basic concepts, and if you don't have a real understanding, no matter how much energy you put in and how much practice you do, you can't get a really stable score.
Which of the following options expresses the same meaning as the above statement?
a.Only with a real understanding of the basic concepts can we achieve truly stable good results.
b.Unless there is a real understanding of the basic concepts, you cannot achieve truly stable good results.
c.As long as you have a real understanding of the basic concepts, you can achieve really stable good results even if you don't put in a lot of effort.
d.If you have achieved really stable good results, it means that you must have a real understanding of the basic concepts.
Analysis] Judging from both the question stem and the options, there are clear hypothetical propositional conjunctions, so it is judged that this question examines the reasoning rules of hypothetical propositions. The question stem conditions can be summarized as follows: 1. Steadily improve your performance in the logic test and have a real understanding of the basic concepts; 2. Without a real understanding of the basic concepts, it is impossible to achieve truly stable good results.
Item A, Reasoning Relationship: Achieve a really stable good score with a real understanding of the basic concepts. Negation of the posterior of 2 can give the negation of the antecedent, which has the same meaning as the stem.
Item B, Reasoning Relationships: Achieving Really Consistent Good Grades with a real understanding of basic concepts. Negation of the posterior of 2 can give the negation of the antecedent, which has the same meaning as the stem.
C, Reasoning Relationship: Have a real understanding of the basic concepts and achieve a really stable good score. The antecedent of negation 2 does not allow for valid reasoning and has a different meaning from the stem.
Item d, Reasoning Relationship: Achieving a Really Stable Good Score with a real understanding of the basic concepts. Negation of the posterior of 2 can give the negation of the antecedent, which has the same meaning as the stem.
Therefore, C is selected for this question.
Therefore, for hypothetical propositions, only by clarifying the relationship between the conjunctive words and the introduction of the question stem can we lay a good foundation for doing the question quickly and accurately, and I hope that you can skillfully use the method of rapid judgment of the conjunctive word in the follow-up brushing questions to improve the accuracy and speed of your own questions.
