1. The four large carnivores currently distributed in the giant panda distribution area, namely jackals, wolves, leopards and snow leopards , have all seen their distribution areas shrink significantly since the mid-20th century, with jackals being the most serious. In the past 10 years, jackals and wolves have only been recorded sporadicly in the giant panda distribution area (jackals have been recorded only 4 times and wolves 11 times), and may be on the verge of disappearing in some mountain systems. The plight of large carnivores is in stark contrast to the effective conservation of giant pandas. The reason may be that large carnivores are at the top of the food chain and have far more stringent requirements for habitat area and quality than other animals.
Based on the above paragraph, it can be deduced:
A. Providing large-area, high-quality habitats may be the key to retaining large carnivores
l0 CComprehensive protection of giant pandas has greatly squeezed the living space of large carnivores
DMaintaining the integrity and authenticity of the ecosystem can enable large animals to be fully protected
2. The county is a relatively independent society, not just a part of the overall society. Each county has its own social structure, social relations, social behavioral norms and unique lifestyle, culture and language traditions, so it is a sub-society. Moreover, county society is a complex social system, consisting of various sub-systems such as villages, towns and cities. Each sub-system forms relationships in different ways and mechanisms, thereby constructing county society.
This article mainly talks about:
The practical significance of County A
The relative independence of County B
The sociological concept of County C
The subsystem composition of County D
3. Looking at the animals and plants in nature, blue is an extremely rare color, and there is almost no blue food in the food we eat. Blue pigments were difficult to obtain until the accidental invention of Prussian blue, or iron ferrocyanide, in the early 18th century. The bright, saturated blue that the painter painted at that time mainly came from a precious mineral - Afghan lapis lazuli. lapis lazuli is ground into powder to prepare a stable blue pigment " ultramarine ". These precious stones flowed from Central Asia to Europe and China through the Silk Road, becoming a mysterious and gorgeous touch of color in the painter's paintings. We can find this kind of blue in the murals of Mogao Grottoes . Because of its rarity, lapis lazuli was once several times more expensive than gold.
This paragraph mainly introduces:
A The reason why blue is extremely rare in nature
B The blue pigment used in ancient paintings
C The use of lapis lazuli in the Mogao Grottoes murals
D The impact of the Silk Road on cultural exchanges between China and the West
4. Dutch researchers unexpectedly discovered a new organ in the human body - a group of salivary glands located deep behind the nose and deep in the upper throat. This group of salivary glands, which average about 4 centimeters in length, are located on a piece of cartilage called the Eustachian tube protuberance. The researchers call them " Eustachian tube salivary glands ". They are likely used by the body to moisten the upper throat. It was previously known that there are three major salivary glands in the human body, namely the parotid gland, the submandibular gland and the sublingual gland . This humble Eustachian tube salivary gland may affect cancer treatment. When using radiation therapy to treat cancer in the head and neck area, doctors should try to avoid irradiating this salivary gland, because damaging these glands may affect the patient's ability to eat, swallow, and even speak.
The most suitable title for this text is:
A. How much is known about human salivary glands
B. New methods for treating cancer
C. New discoveries of hidden organs in the human body
For children, the online games they are suitable to play are "clearly arranged", making them safer to play. For parents, they can more clearly evaluate whether an online game is suitable for their children and can manage it with more confidence.The one with "complex feelings" is undoubtedly the gaming company. The usage requirements and scenarios stipulated in age-appropriate reminders are directly related to game companies. The logo must be eye-catching enough for players to see and understand. This is a mandatory requirement for game companies. It is also a setback for those online game companies and online game products that rely on side-stepping and other means to attract players. But this kind of "restraint" is necessary, because the protection of minors is a norm that all market entities, including game companies, must abide by, and it is also a social responsibility that must be borne.
The "restraint" in the article most likely refers to:
A. Remove online games that are not suitable for minors
B. Control the online time and duration of games to prevent minors from being addicted
C. Classify and label online games according to appropriate age
D. Relevant departments adopt more stringent review measures for game products
Reference answer for political education:
1. Item A, according to "The distress of large carnivores forms a clear contrast with the effective protection of giant pandas. The reason may be mainly that large carnivores are in a "At the top of the food chain, the requirements for habitat area and quality are much more stringent than for other animals." It can be seen that the reason for the distress of large carnivores is: because they are at the top of the food chain, the requirements for habitat area and quality are very high and very demanding. Therefore, it can be deduced that "providing large areas, high quality "The amount of habitat may be the key to retaining large carnivores", elected;
Item B, according to "The distress of large carnivores and the effective protection of giant pandas form a clear contrast", it can be seen that the protection of giant pandas does not mention benefiting them. Other animals, this item is contrary to the meaning of the text, excluded;
Item C, the original text does not emphasize that the protection of giant pandas will affect the survival of large carnivores, there is no necessary connection between the two, this item imposes cause and effect, excluded;
Item D, according to "Four species of large carnivores currently distributed in the giant panda distribution area" and "The distress of large carnivores is in obvious contrast with the effective protection of giant pandas. The reason may be mainly that large carnivores are at the top of the food chain and have a negative impact on the habitat. "The volume and quality requirements are far more stringent than other animals." It can be seen that the paragraph focuses on large carnivores, so the scope of "large animals" is expanded; and the paragraph "maintaining the integrity and authenticity of the ecosystem" and "comprehensive protection" are not mentioned, so this item is made out of nothing and excluded.
Therefore the correct answer is A.
2. The article first points out that the county is a relatively independent society, and explains it from the aspects of social structure, social relations, and lifestyle. Next, it is discussed that county society is a complex social system, consisting of sub-systems such as villages and towns. Therefore, the paragraph explains the concept of "county" from two aspects: "relative independence" and "complexity", corresponding to item C.
| Item A, "realistic significance" is made out of nothing, and is excluded;
| Item B, "relative independence" is one-sided, and is excluded;
| Item D, "subsystem composition" corresponds to complexity, and is one-sided, and is excluded.
Therefore the correct answer is C.
3. The paragraph begins by pointing out that blue is extremely rare among animals and plants in nature, and then discusses how blue pigments are rare before Prussian blue was accidentally invented in the early 18th century. The blue in the painter's painting mainly comes from Afghan lapis lazuli to argue that blue pigments are rare. Then it points out that this stone needs to flow to other places through the Silk Road, and uses the Mogao Grottoes murals as an example to demonstrate. The last sentence once again discusses that the raw material for blue pigments, lapis lazuli, is expensive. Therefore, the paragraph mainly introduces the relevant situation of blue pigment used in ancient paintings, corresponding to item B.
Item A, the paragraph begins by stating that "Looking at animals and plants in nature, blue is an extremely rare color." However, the paragraph does not mention the reason why blue is rare in nature, so the "rare reason" is made out of nothing, and the paragraph focuses on "blue". "color pigment", the scope of "blue" is expanded and excluded;
Item C, "Mogao Grottoes murals" only corresponds to the content of the example part of the paragraph, is not the focus, excluded;
Item D, the topic keyword "blue pigment" is missing, excluded.
Therefore the correct answer is B.
4. The article first points out that Dutch researchers have discovered a new organ - the "Eustachian tube salivary gland", and then introduces its length, location, function, and precautions - doctors should avoid irradiating the Eustachian tube salivary gland when performing radioactive therapy to treat cancer, and analyze the reasons. It can be seen that the article mainly discusses the organ newly discovered by the researchers-the Eustachian tube salivary gland, which corresponds to item C.
Item A, the scope of "human salivary glands" has been expanded and excluded;
Item B, the text only states that doctors should avoid irradiating the Eustachian tube salivary glands when treating cancer with radiotherapy, which is a contraindication for the treatment of cancer. This is not a "new method of treating cancer", excluded;
Item D, which only corresponds to the content of radioactive treatment in the last sentence, is one-sided and excluded.
Therefore the correct answer is C.
5. For word and sentence comprehension questions, "binding" appears in the last sentence of the paragraph and is guided by "this kind", so the referent should be found from the previous text. The first sentence of the article points out that suitable online games should be matched based on the player's age, and then points out the benefits of doing so. The following paragraph introduces the need for game companies to mark the usage requirements and scenarios stipulated in age-appropriate reminders. The last sentence appears "this kind of 'restraint'", so "restraint" refers to the identification of usage requirements and scenarios stipulated in age-appropriate reminders, which corresponds to item C.
Item A "Remove online games that are not suitable for minors", item B "Control the online time and duration of games", and item D "Relevant departments adopt more stringent review measures for game products" are not mentioned in the paragraphs. They are made out of nothing and excluded.
Therefore the correct answer is C.
