Aggression
When one animal attacks another, it engages in the most obvious example of aggressive behavior. Psychologists have adopted several approaches to understanding aggressive behavior in people.
The Biological Approach. Numerous biological structures and chemicals appear to be involved in aggression. One is the hypothalamus, a region of the brain. In response to certain stimuli, many animals show instinctive aggressive reactions. The hypothalamus appears to be involved in this inborn reaction pattern: electrical stimulation of part of the hypothalamus triggers stereotypical aggressive behaviors in many animals. In people, however, whose brains are more complex, other brain structures apparently moderate possible instincts.
An offshoot of the biological approach called sociobiology suggests that aggression is natural and even desirable for people. Sociobiology views much social behavior, including aggressive behavior, as genetically determined. Consider Darwin’s theory of evolution. Darwin held that many more individuals are produced than can find food and survive into adulthood. A struggle for survival follows. Those individuals who possess characteristics that provide them with an advantage in the struggle for existence are more likely to survive and contribute their genes to the next generation. In many species, such characteristics include aggressiveness. Because aggressive individuals are more likely to survive and reproduce, whatever genes are linked to aggressive behavior are more likely to be transmitted to subsequent generations.
The sociobiology view has been attacked on numerous grounds. One is that people’s capacity to outwit other species, not their aggressiveness, appears to be the dominant factor in human survival. Another is that there is too much variation among people to believe that they are dominated by, or at the mercy of, aggressive impulses.

The Psychodynamic Approach. Theorists adopting the psychodynamic approach hold that inner conflicts are crucial for understanding human behavior, including aggression. Sigmund Freud, for example, believed that aggressive impulses are inevitable reactions to the frustrations of daily life. Children normally desire to vent aggressive impulses on other people, including their parents, because even the most attentive parents cannot gratify all of their demands immediately. Yet children, also fearing their parents’ punishment and the loss of parental love, come to repress most aggressive impulses. The Freudian perspective, in a sense: sees us as "steam engines." By holding in rather than venting "steam," we set the stage for future explosions. Pent-up aggressive impulses demand outlets. They may be expressed toward parents in indirect ways such as destroying furniture, or they may be expressed toward strangers later in life.
According to psychodynamic theory, the best ways to prevent harmful aggression may be to encourage less harmful aggression. In the steam-engine analogy, verbal aggression may vent some of the aggressive steam. So might cheering on one’s favorite sports team. Psychoanalysts, therapists adopting a psychodynamic approach, refer to the venting of aggressive impulses as "catharsis." Catharsis is theorized to be a safety valve. But research findings on the usefulness of catharsis are mixed. Some studies suggest that catharsis leads to reductions in tension and a lowered likelihood of future aggression. Other studies, however, suggest that letting some steam escape actually encourages more aggression later on.
The Cognitive Approach. Cognitive psychologists assert that our behavior is influenced by our values, by the ways in which we interpret our situations and by choice. For example, people who believe that aggression is necessary and justified-as during wartime-are likely to act aggressively, whereas people who believe that a particular war or act of aggression is unjust, or who think that aggression is never justified, are less likely to behave aggressively.
One cognitive theory suggests that aggravating and painful events trigger unpleasant feelings. These feelings, in turn, can lead to aggressive action, but not automatically. Cognitive factors intervene. People decide whether they will act aggressively or not on the basis of factors such as their experiences with aggression and their interpretation of other people’s motives. Supporting evidence comes from research showing that aggressive people often distort other people’s motives. For example, they assume that other people mean them harm when they do not.
Catharsis: In psychodynamic theory, the purging of strong emotions or the relieving of tensions.
Paragraph 2: The Biological Approach. Numerous biological structures and chemicals appear to be involved in aggression. One is the hypothalamus, a region of the brain. In response to certain stimuli, many animals show instinctive aggressive reactions. The hypothalamus appears to be involved in this inborn reaction pattern: electrical stimulation of part of the hypothalamus triggers stereotypical aggressive behaviors in many animals. In people, however, whose brains are more complex, other brain structures apparently moderate possible instincts.
1. According to paragraph 2, what evidence indicates that aggression in animals is related to the hypothalamus?
Some aggressive animal species have a highly developed hypothalamus.
Electrical stimulation of the hypothalamus delays animals’ inborn reaction patterns.
Animals behaving aggressively show increased activity in the hypothalamus.
Animals who lack a hypothalamus display few aggressive tendencies.
Paragraph 3: An offshoot of the biological approach called sociobiology suggests that aggression is natural and even desirable for people. Sociobiology views much social behavior, including aggressive behavior, as genetically determined. Consider Darwin’s theory of evolution. Darwin held that many more individuals are produced than can find food and survive into adulthood. A struggle for survival follows. Those individuals who possess characteristics that provide them with an advantage in the struggle for existence are more likely to survive and contribute their genes to the next generation. In many species, such characteristics include aggressiveness. Because aggressive individuals are more likely to survive and reproduce, whatever genes are linked to aggressive behavior are more likely to be transmitted to subsequent generations.
2. According to Darwin’s theory of evolution, members of a species are forced to struggle for survival because
Not all individuals are skilled in finding food
Individuals try to defend their young against attackers
Many more individuals are born than can survive until the age of reproduction
Individuals with certain genes are more likely to reach adulthood
Paragraph 5: The Psychodynamic Approach. Theorists adopting the psychodynamic approach hold that inner conflicts are crucial for understanding human behavior, including aggression. Sigmund Freud, for example, believed that aggressive impulses are inevitable reactions to the frustrations of daily life. Children normally desire to vent aggressive impulses on other people, including their parents, because even the most attentive parents cannot gratify all of their demands immediately. Yet children, also fearing their parents’ punishment and the loss of parental love, come to repress most aggressive impulses. The Freudian perspective, in a sense: sees us as "steam engines." By holding in rather than venting "steam," we set the stage for future explosions. Pent-up aggressive impulses demand outlets. They may be expressed toward parents in indirect ways such as destroying furniture, or they may be expressed toward strangers later in life.

1. 3
This is a Factual Information question asking for specific information that can be found in paragraph 2. The correct answer is choice 3. The question asks specifically for "evidence that indicates that aggression in animals is related to the hypothalamus." Answer choices 1 and 2 are contradicted by the paragraph. Choice 2 is incorrect because, while the paragraph states that "electrical stimulation" triggers aggressive behavior in many animals, this is not "evidence" in itself, but merely support for the more general statement in choice 3 that increased hypothalamus activity, in general, is related to aggression.

以上内容为OG给出的解释，但本人认为此题无正确选项。因为C选项中的increased activity为原文未提及内容，因此C项不正确。
B选项中artificial错误，因为我们不能从原文当中的电刺激海马体导致动物侵略性推出人工的刺激海马体能导致动物侵略性，这个是一个以偏概全的结论，因此建议将B选项中的artificial改为electrical，则B选项为正确选项。
2. 3
This is a Factual Information question asking for specific information that can be found in the passage. The correct answer is choice 3, "many more individuals are born than can survive until the age of reproduction." This answer choice is essentially a paraphrase of paragraph 3, sentence 4: "Darwin held that many more individuals are produced than can find food and survive into adulthood." Choices 1 and 2 are not mentioned at all. Choice 4 may be true, but it is not stated in the passage as a fact; an inference is needed to support it.
3. 1
This is a Vocabulary question. The word being tested is inevitable. It is highlighted in the passage. The correct answer is choice 1, unavoidable. If something is inevitable, that means that it will occur no matter what; in other words, it is unavoidable.
4. 3
This is a Vocabulary question. The word being tested is gratify. It is highlighted in the passage. The correct answer is choice 3, "satisfy." If a person’s desires are gratified, those desires are fulfilled. Thus the person is satisfied.
5. 2
This is a Reference question. The word being tested is they. It is highlighted in the passage. The correct answer is choice 2, "pent-up aggressive impulses." This is a simple pronoun-referent item. The word the?) here refers to something that "may be expressed toward strangers later in life." This is the "outlet" toward which the "aggressive impulses" mentioned may be directed.
6. 2
This is a Factual Information question asking for specific information that can be found in paragraph 5. The correct answer is choice 2, "a fear that their parents will punish them and stop loving them." The question asks what causes the conflict between the desire to vent aggression and children’s fears. The answer is found in paragraph 5 in the sentence that reads, "Yet children, also fearing their parents’ punishment and the loss of parental love, come to repress most aggressive impulses." Answer choice 2 is the only choice that correctly identifies the cause of the conflict created by repressing aggression in children.
7. 3
This is a Rhetorical Purpose question. If asks you why the author mentions that Freud described people as "steam engines" in the passage. The phrase being tested is highlighted in the passage. The correct answer is choice 3, "must vent their aggression to prevent it from building up.’’ Steam engines will explode if their steam builds up The same is true of people, as choice 3 indicates. The other choices are not necessarily true of both people and steam engines, so they are incorrect.
8. 2
This is a Sentence Simplification question. As with all of these items, a single sentence in the passage is highlighted:
For example, people who believe that aggression is necessary and justified-as during wartime-are likely to act aggressively, whereas people who believe that a particular war or act of aggression is unjust, or who think that aggression is never justified, are less likely to behave aggressively.
The correct answer is choice 2. It contains all of the essential information in the highlighted sentence. The highlighted sentence compares people who believe particular acts of aggression are necessary and those who don’t, in terms of their relative likelihood to act aggressively under certain conditions. This is precisely what choice 2 says: "People who believe that aggression is necessary and justified are more likely to act aggressively than those who believe differently." It compares the behavior of one type of person to that of another type of person. Nothing essential has been left out, and the meaning has not been changed. Choice 1 changes the meaning of the sentence; it says categorically that "those (people) who believe that they are fighting an unjust war do not (act aggressively)." The highlighted sentence merely says that such people are "less likely" to act aggressively, not that they never will; this changes the meaning. Choice 3 says, "People who normally do not believe that aggression is necessary and justified may act aggressively during wartime." This is incorrect because it leaves out critical information: it does not mention people who do believe aggression is necessary. This choice does not make the same comparison as the highlighted sentence. Choice 4, "People who believe that aggression is necessary and justified do not necessarily act aggressively during wartime," also changes the meaning of the sentence by leaving out essential information. In this choice, no mention is made of people who do not believe aggression is necessary. This choice does not make the same comparison as the highlighted sentence.
9. 3
This is a Negative Factual Information question asking for specific information that can be found in paragraphs 7 and 8. Choice 3 is the correct answer. Choice 1, "moral values," is explicitly mentioned as one of the influences on aggressive behavior; so it is incorrect. Choices 2 (“previous experiences”) and 4 sentence in paragraph8 says, “People decide whether they will act aggressively of not on the basis of factors such as their experiences with aggression and their interpretation of other people’s motives.” Choice 3, the “instinct to avoid aggression,” is not mentioned, so it is the correct answer here.
10. 2
This is a Vocabulary question. The word being tested is distort . It is highlighted in the passage. The correct answer is choice 2, "misinterpret." To distort other people’s motives is to twist them, or view them incorrectly and thereby not understand them properly. Something that is not understood properly is misinterpreted.
11. 2
This is an Insert Text question. You can see the four black squares in paragraph 5 that represent the possible answer choices here.
The Psychodynamic Approach. Theorists adopting the psychodynamic approach hold that inner conflicts are crucial for understanding human behavior, including aggression. Sigmund Freud, for example, believed that aggressive impulses are inevitable reactions to the frustrations of daily life. Children normally desire to vent aggressive impulses on other people, including their parents, because even the most attentive parents cannot gratify all of their demands immediately. Yet children, also fearing their parents’ punishment and the loss of parental love, come to repress most aggressive impulses. The Freudian perspective, in a sense, sees us as "steam engines." By holding in rather than venting "steam," we set the stage for future explosions. Pent-up aggressive impulses demand outlets. They may be expressed toward parents in indirect ways such as destroying furniture, or they may be expressed toward strangers later in life.
The sentence provided, "According to Freud, however, impulses that have been repressed continue to exist and demand expression," is best inserted at square 2. Square 2 is correct because the sentence being inserted is a connective sentence, connecting the idea of childhood repression in the preceding sentence to the "Freudian perspective" in the sentence that follows. The use of the word however in this sentence indicates that an idea already introduced (the repression of children’s aggressive impulses) is being modified. Here, the inserted sentence tells us that Freud thought that even though these impulses are repressed, they continue to exist. This serves as a connection to the next sentence and the "Freudian perspective." Inserting the sentence at square 1 would place the modification ("however, impulses . . . continue to exist") before the idea that it modifies (repression of impulses). This makes no logical sense. Inserting the sentence at square 3 would move the modifying sentence away from its logical position immediately following the idea that it modifies (repression of impulses). Placing the insert sentence at square 4 moves the sentence farther from its logical antecedent and has no connection to the sentence that follows it.
