1, answer D. analysis: test site: negative proposition ★ The original proposition is equivalent to the negative proposition, and the truth is the same ★.
The stem of the question is true, and both synonymous reporting and the negative proposition of the original proposition can be selected. The stem of the question is: "Direction deviation? Subversive error ",options A and B made the same mistake," Subversive error? Direction deviation ",backwards, C option," Non-direction deviation? Non-subversive error "is incorrect, option D," Non-subversive error? "Non-directional deviation" is a negative proposition of the stem. Correct, choose D. ..
2. Answer B. Analysis: Test center: Contradictory proposition ★ Both sides of contradiction are always true and false ★.
Is it sunny on the weekend? Playing tennis with baking soda shows that Xiao Li didn't fulfill his promise, that is, he found a contradiction: "The weather was fine at the weekend, and he didn't play tennis with baking soda", so he chose B.
3. Answer A. Analysis: Test site: contradictory proposition+other propositions
★ It is known that the original proposition is true, whether it is true or not, it must be true; Contradictions must be false; Other than that, I'm not sure if it's true or not.
Topic: ① Real power? Major events, ② Virtual rights? The truth, ③ wrong? A good term "powerless" is actually "powerless", which is the negative proposition of ③. If ③ is true, then the contradiction must be false. Other options, except the original proposition, negative proposition and contradictory proposition, are all uncertain propositions, so they may all be true and not selected. So, the answer is a.
4. On a section of expressway, there are five small towns, which are known as follows: (1) Charlotte Town is not adjacent to Gujing Town or Lianhua Town; (2) Huanxi Town faces neither Weizi Town nor Hehua Town; (3) Weizi Town faces neither Gujing Town nor Hehua Town; (4) There are no wooden pagodas in Charlotte Town; (5) Towns with wooden towers rank first and fourth.
Thus, the second town is:

Mei Ju is the four daughters of Zhang Laohan. Once, a guest asked the four sisters' ages and got different answers. Mei said, "orchids are smaller than bamboo." Lan said, "I am younger than Mei." Zhu Yun said, "Lan is not Third Sister." Ju said, "I am my sister." The simple and honest Zhang Laohan added: "The eldest daughter and the third daughter lie, and the second daughter and the younger daughter are right."
Accordingly, according to the order of age from big to small, it can be judged that the four sisters are:
A. Meiju B. Meiju
C. Cymbidium hybridum
6. Three male students, Ma Ming, Liu Jian and Zhang Yi, each have a sister. On this day, six people play badminton together, hold mixed doubles for men and women, and stipulate that brothers and sisters are not allowed to be companions.
The situation in the first game is: Liu Jian and Xiaoping versus Zhang Yi and Xiaoying.
In the second game, Zhang Yi and Xiaohong played against Liu Jian and Ma Ming's sister.
According to the conditions of the question, which of the following is correct?
Liu Jian and Xiaohong, Ma Ming and Xiaoying, Zhang Yi and Xiaoping are brother and sister.
Liu Jian and Xiaoying, Ma Ming and Xiaoping, Zhang Yi and Xiaohong are brother and sister.
Liu Jian and Xiaoping, Ma Ming and Xiao Ying, Zhang Yi and Xiaohong are brother and sister.
Liu Jian and Xiaohong, Ma Ming and Xiaoping, Zhang Yi and Xiaoying are brother and sister.
4. Answer A. Analysis: Among the five conditions in the title, Lotus Town was mentioned three times, with the highest frequency, which is a breakthrough. According to (1)(2)(3), Lianhua Town can only face Gujing Town. According to (1)(3), the other side of Gujing Town is adjacent to Huanxi Town, and Huanxi Town ranks third. According to (2), Huanxi Town is adjacent to Xialuo Town, which ranks second or fourth. According to (4) and (5), Xialuo Town is not the first or fourth, so Xialuo Town ranks second, so the answer is A. Another solution: According to (2) and (3), Weizi Town can only be adjacent to Xialuo Town, and Xialuo Town ranks second or fourth; As can be seen from (4) and (5), Charlotte Town can only rank second, so the answer is A.
5. Answer B. Analysis: By comparing the stem information, what Zhang Laohan said is true. From the words of "the eldest daughter and three girls lie" and Ju, we can know that Ju is definitely not the eldest daughter, so Ju lies, so it can be concluded that Ju is three girls. By comparing the options, A, C and D can be excluded, so the answer is B.
6. Answer A. Analysis: According to the question that brothers and sisters are not partners, we know that Liu Jian and Xiaoping are not brothers and sisters, excluding C; Zhang Yi and Xiaoying are not brothers and sisters, not including D; Zhang Yi and Xiaohong are not brother and sister, so B is excluded. Therefore, choose a in this question.
7. "Only when problems are found can problems be solved." The following options cannot accurately express the above meaning:

8. Mr. Li, Mr. Zhang and Mr. Wang teach Chinese, Mathematics and English in a boarding junior high school respectively. There are three kinds of guesses about the subjects taught by the three of them:
(1) Teacher Li teaches Chinese and Teacher Zhang teaches mathematics;
(2) Miss Li teaches mathematics and Miss Wang teaches Chinese;
Teacher Zhang teaches English and teacher Wang teaches Chinese.
If the above three guesses are only half right, the following options must be established:
A. Miss Li teaches Chinese, and may also teach math.
B. Mr. Zhang teaches mathematics and may also teach Chinese.
C. Miss Wang may teach Chinese or English.
Teacher Li teaches English, teacher Zhang teaches math and teacher Wang teaches Chinese.
7. answer B. analysis: first of all, we judge the relationship between the topic and the option through the context of related words. Question stem: Solve the problem => Find the problem. Answer: Solving the problem => Finding the problem, B: Finding the problem => Solving the problem, C: Solving the problem => Finding the problem, D: Not finding the problem => Not solving the problem. The second step is to judge whether the proposition is correct by denying the whole story. AC is "before you agree", D is "after you disagree", and only B is incorrect.
8. Answer D. Analysis: As can be seen from the stem of the question, the conjectures of the three people have the same expression, so we should look for relevant sentences. Observe that "Teacher Li teaches Chinese" in (1) is a related sentence, because the first half of the sentence in (2) has "Teacher Li" and the second half has "Teaching Chinese", so "Teacher Li teaches Chinese".
The above questions come from Chinese public education.
