In order to help students better prepare for the exam, 5 test questions are sorted out every day for candidates to practice Xi.
01 When a company opened its recruitment this year, the average number of applicants for each position decreased by 10% compared with last year. As a result, the company has become less attractive to job seekers.
One of the following that most weakens the above inference is ( ).
a.This year, the number of new graduates nationwide has decreased by about 10% compared with last year.
b.This year, both the national and provincial civil servants have increased the number of applicants compared to previous years.
c.Fifty percent of the positions the company has hired this year to improve its employment standards.
d.The company is hiring more candidates for some of its positions this year than last year.
In 021995, Chinese athletes won a total of 103 world championships in major sports competitions around the world. 57 world records have been set, the most in historyIn 1995, only 15 of China's high school students went on to university to pass the medical examination.
Therefore, we can correctly conclude that in 1995, (
a.China has become a world sports power.
b.Only 15% of high school students in China go on to college.
c.Competitive sports in China have reached an all-time high.
d.The standard of physical examination for university entrance has been improved.

Originally from Germany, he speaks Chinese.
Originally from Japan, he speaks German.
The seating arrangements for the six delegates shall be as follows ( ).
a.①②b.④⑥
c.①②d.③⑤
04The beautiful color of corals in the ocean comes from the algae organisms that coexist with them in their bodies, among which zooxanthellae is the most important type of single-celled seaweed. They each take what they need and want to provide food to each other. The warming of the sea caused by global warming has led to the mass death of algae such as zooxanthellae, which in turn causes the death of corals themselves and caused coral bleaching, but studies have found that corals can cope with the challenges of climate warming by choosing other heat-tolerant algae organisms.
Which of the following, if true, would weaken this finding?（
a.Some zooxanthellae are able to tolerate higher sea temperatures than other algae that tolerate heat.
b.The formation of heat tolerance in some algae requires a long-term process.
c.Some zooxanthellae gradually adapt to the increase in sea temperature and survive.
d.Dead heat-tolerant algae have also been found in some bleached coral reefs.
05 It has been suggested that the concentration of milk is related to the organic grass that cows eat. In order to test this idea, the following experimental methods are the most reliable ( ).
a.Cows with good breeds were selected as experimental samples.
b.The test compared the nutrient content of organic forage with that of modified forage.
c.Whenever possible, two batches of cows of the same breed and grade were selected, one fed with organic grass and the other with fertilised pasture, and after a period of time, the concentration of milk produced by the two batches was compared.
d.Gradually reduce or increase the proportion of organic pasture in the diet of the same cows, compared with the concentration of milk produced by the same cows at different times.
Reference and Analysis
01 Answer: cAnalysis: Step 1: Find Arguments and Arguments The argument for this question is that "the company has become less attractive to job applicants". The argument is that "the average number of applicants per position has decreased by 10% compared to last year". Step 2: Determine the way to weaken the argument that the company is less attractive to job seekers, argue that the number of applicants is said to be decreasing, and that there is a causal relationship between the argument and the argument, and the argument needs to be weakened. Step 3: Judge the role of options one by one In C, "Fifty percent of the positions recruited this year have improved their employment standards", and the argument states that "the average number of applicants per position has decreased by 10% compared to last year", which indicates that the attractiveness of the whole company has increased, and C directly weakens the argument, so C is correct. "The number of fresh graduates nationwide this year has decreased by about 10% compared with last year" and "the number of civil servants applying for the company this year has increased compared with previous years" in case B does not mean that the number of applicants for the company is more or less than last year, so it does not mean that the attractiveness of the company has increased or decreased, so A and B are wrong. "More applicants for some of the positions hired this year than last year" in D indicates that some of the company's positions have increased, but it does not mean that the attractiveness of the whole company has increased, and part D weakens the argument, and D does not weaken to the same extent as C. Therefore, the correct answer is c. 02 Answer: cAnalysis: Step 1: Grasp the main message of the question stem The first sentence states that Chinese players won 103 world championships in 1995, the second sentence explains that Chinese players set 57 world records in 1995, which is the highest in history, and the third sentence explains that only 15% of China's high school students who entered universities in 1995 passed the physical examination. Step 2: Analyze the information of the question stem and combine the options to get the answer Item A: China has become a "world sports power", which is too absolute and the question stem is not involved, so it cannot be obtained;Item B: Only 15% of high school students in China go on to university, which is not covered in the question stem, which only explains that "only 15 of the high school students in China who go to university pass the physical examination", so it cannot be obtained;Item C: China's competitive sports have reached the highest peak in history, and it can be concluded that the statement in C is correct from the question stem "In 1995, Chinese players created 57 world records, which is the highest in history".Item D: "University Entrance Physical Examination Criteria" is not covered in the stem, it is an irrelevant option, so it is not known. In summary, the correct answer is c. 03 Answer: cAnalysis: According to the question stem requirement "6 delegates can talk freely", it can be seen that the two people next to each other should be able to speak the same language. Through the analysis, it is observed that each option gives a complete seat arrangement, and it is noted that the positive analysis is not easy, so the method of substitution option exclusion can be used in this question. item a: and next to each other, but neither of them speaks the same language, so the arrangement in a does not meet the requirements;Item B: and next to each other, but neither of them speaks the same language, so the arrangement in B does not meet the requirements;Item c: The order in the options meets the requirements;Item D: and next to each other, but neither of them speaks the same language, so the arrangement in D does not meet the requirements. In summary, the correct answer is c. 04 Answer: dAnalysis: Step 1: Find the argument and the argument The argument is that research has found that corals can cope with the challenges of climate change by selecting other heat-tolerant algae organisms, for example. The argument is that the warming of the sea caused by global warming has led to the mass death of algae such as zooxanthellae, which in turn has caused the death of corals themselves. Step 2: Determine the mode of weakening To constitute weakening, the argument can be weakened so that the coral cannot survive through other heat-tolerant algal pathways. Step 3: Judge the role of the options one by one Item A states that the warming of the seawater may also cause the death of other heat-tolerant algae, but some do not represent all, and it may be that most of the zooxanthellae tolerate the seawater temperature is not as high as that of other heat-tolerant algae, and the degree of weakening is limitedB and C have no obvious relationship with the argument and are irrelevant. Item d directly undermines the argument by stating that other heat-tolerant algae do not necessarily help corals cope with climate warming. Therefore, the correct answer is d. 05 Answer: cAnalysis: This question examines the comparative test, then the stem is to discuss the relationship between milk concentration and organic forage, then there need to be two objects at the same time: milk concentration and forage, options A and B only mention one object exclusion, option D mentions the proportion of organic forage, and the problem of proportion is not mentioned in the question stem, so D is excluded. Option C mentions milk concentration and the presence or absence of organic pasture for comparative testing. Therefore, option C is selected for this question.
