[解析]

（1）D.细节理解题。根据上文As your teacher passes out the math test，your palms turn sweaty.You notice that your heart has begun to race.Glancing down at the page，you suddenly forget those operations on which you had drilled only a few days earlier.Do you perform all additions first in a complex calculation？（当老师分发数学试卷时，你的手心开始冒汗。你注意到你的心脏开始加速。瞟一眼这一页，你就会突然忘记几天前练过的那些练习。在复杂计算中，是否先算了所有加法？）结合后文Suddenly，you start to doubt a lot of things that you know.（你会突然开始怀疑你所知道的许多事情。）由此可知，本句承接上文说明，上文这种发试卷时的感受，很多人都经历过，都知道这种感受。故D选项"哦，你知道的﹣﹣你很肯定，对吧？"符合上下文语境，故选D。
（2）F.推理判断题。根据上文Or maybe not Even researchers who study this condition note that it can be surprisingly hard to define （下定义） math anxiety.（甚至研究这种情况的研究人员也没有注意到，要给"数学焦虑"下定义是非常困难的。）由此可知，本句是在说明，因为要给"数学焦虑"下定义是非常困难的，所以很难确定有多少人患有数学焦虑症，毕竟这不像抑郁症那样被官方认可为精神障碍。故F选项"也很难确定到底有多少人患有数学焦虑症。"符合上下文语境。故选F。
（3）E.段落大意题。根据后文It asks things like "how anxious would you feel about being given a set of division problems to solve on paper"．Those who score high on these surveys about stress over making calculations related to numbers will be labeled math anxious.（它问的问题是"当你被要求在纸上解决一组除法问题时，你会有多焦虑"。那些在计算相关数字时压力方面得分高的人会被贴上"数学焦虑"的标签。）由此可知，本段是在说明研究人员进行的一项问卷调查，以此来诊断出数学焦虑症。故E选项"为了诊断数学焦虑症，研究人员进行了一项问卷调查。"符合上下文语境。故选E。
（4）A.细节理解题。根据上文In general，people who panic over their math skills tend to do worse in math classes than people who don't mind numbers.（一般来说，那些对自己的数学能力感到恐慌的人在数学课上的表现往往比那些不介意数字的人要差。）结合后文"Just because you're math anxious，that doesn't always mean you're bad at math，" notes Rose Vukovic，an educational psychologist at the University of Minnesota in Minneapolis.（明尼阿波利斯明尼苏达大学的教育心理学家Rose Vukovic指出："仅仅因为你有数学焦虑，并不总是意味着你数学不好。"）由此可知，上文说明的"那些对自己的数学能力感到恐慌的人在数学课上的表现往往比那些不介意数字的人要差。"这种情况并不总是真的。故A选项"但这并不总是真的。"符合上下文语境，故选A。
（5）C.细节理解题。根据后文Throughout life，this type of stress can stand in the way of mastering skills or projects in a host of areas that rely on calculations.（在人的一生中，这种类型的压力会阻碍掌握许多依赖计算的领域的技能或项目。）由此可知，数学焦虑症的影响并不会在毕业时就结束。故C选项"它的影响不会在毕业时结束。"符合上下文语境，故选C。

202265. （2022•西安三中•五模） From Mozart to pop music，tons of people enjoy listening to various types of music while they paint，write，or draw．Many believe that music helps improve creativity．But an international study is challenging that viewpoint．（1）
   To come to their conclusions，researchers had participants complete verbal （文字的） problems designed to inspire creativity while sitting in a quiet room．（2）        They found that background music significantly hurt the participants，ability to complete tasks associated with verbal creativity．The tasks were simple word games．（3）        Then，they were asked to find a single word associated with all three that could be combined to form a common phrase or word．Participants completed the tasks in either a quiet room，or while exposed to three different types of music：music with unfamiliar lines，instrumental music，or music with familiar lines．
   Dr．McLatchie and his colleagues conclude that music interferes with （干扰） the verbal working memory of the brain．（4）       Also，as far as the library background noises having seemingly no effect，the researchers believe that is the case because library noises create an environment of steady state that doesn't interrupt concentration．
   "（5）       Instead，they demonstrate that music，regardless of the presence of its content，consistently interrupts creative performance in insight problem solving，" the study reads．

A．And this in turn holds back creativity．
B．It has nothing to do with the positive reaction．
C．Then again，they were tested while music was played in the background．
D．Psychologists say that their findings indicate music actually blocks creativity．
E．For example，participants were given three words，such as dress，dial，and flower．
F．Before the experiment，the participants didn't study the music they would listen．
G．To conclude，the findings here challenge the popular view that music builds up creativity．

205945. （2016•西北大附中•高二下期末） Feeling both positive and negative emotions is a natural part of being human．We might use the word"negative"to describe more difficult emotions，but it doesn't mean those emotions are bad or we shouldn't have them．Still，most people would probably rather feel a positive emotion than a negative one．（1）       ．
    What matters is how our emotions are balanced-how much of each type of emotion，positive or negative，we experience．
    Negative emotions warn us of threats or challenges that we may need to deal with．For example，fear can alert us to possible danger．（2）       ．Angry feelings warn us that someone is stepping on our toes，crossing a boundary，or violating our trust．Anger can be a signal that we might need to act on our own behalf．
    Negative emotions focus our awareness．（3）       ．But too many negative emotions can make us feel anxious，exhausted，or stressed out．When negative emotions are out of balance，problems might seem too big to handle．
    Positive emotions balance out negative ones，but they have other powerful benefits，too．Instead of narrowing our focus like negative emotions do，positive emotions affect our brains in ways that increase our awareness，attention，and memory．They help us take in more information and hold several ideas in mind at once．（4）       ．
    When positive emotions open us up to new possibilities，we are more able to learn and build on our skills．（5）       ．

A．What helps you feel confident？
B．That leads to doing better on tasks and tests．
C．It's a signal that we might need to protect ourselves．
D．They help us focus on a problem so we can deal with it．
E．For example，it's likely you'd prefer to feel happy instead of sad．
F．And they then make us understand how different ideas relate to each other．
G．Pay attention to these powerful tools and find ways to make time for them．

202208. （2022•长安区一中•五模） At one point or another，you've probably heard someone speak with confidence on a topic that they actually know almost nothing about.This phenomenon is known as the Dunning-Kruger effect.
   In a set of studies，researchers Justin Kruger and David Dunning asked participants to complete tests of their skills in a particular domain（领域）.Then，participants were asked to guess how well they had done on the test.（1）       This effect was most pronounced among participants with the lowest scores on the test.
   In other words，if someone knows very little about a particular topic，they may not even know enough about the topic to realize that their knowledge is limited.Importantly，someone may be highly skilled in one area，but be influenced by the Dunning-Kruger effect in another domain. （2）
   If people who know very little about a topic think they're experts，what do experts think of themselves？Interestingly，Dunning and Kruger found that although experts typically guessed their performance was above average，they didn't realize quite how well they had done.They often make a different mistake：（3）
   What can people do to overcome the effect？Dunning and Kruger once had some of the participants take a logic test and then complete a short training session on logical reasoning.After the training，the participants were asked to assess how they'd done on the previous test.（4）       As a result，the participants who scored in the bottom 25 percent lowered their estimate of how well they thought they had done on the initial test.
   In short，The Dunning-Kruger effect suggests that we may not always know as much as we think we do. （5）       However，by challenging ourselves to learn more，we can work to overcome the effect.

A.Researchers found that the training made a difference.
B.They assume that everyone else is knowledgeable，too.
C.This happens when people know much about a topic.
D.They found that participants tended to overestimate their abilities.
E.All of them had an accurate view of their performance.
F.This means that everyone can potentially be affected by the Dunning-Kruger effect.
G.In some domains，we may not know enough about a topic to realize that we are unskilled.

202617. （2020•西安中学•一模） Building a Lasting Social Relationship
We all know that friends are special people who we share our lives with，and who share their lives with us in return．（1）
   According to research recently published in the Journal of Social and Personal Relationships，the key is to use "we-talk"．
   Led by University of California psychologist Megan Robins and her colleagues，the researchers reviewed and analyzed 30 different studies involving over 5，000 participants．（2）
   The word "we" moves people from an individual position into a partnership，which makes us more interdependent． " （3）       Word use is a window into what people are thinking and feeling without asking them，" Robbins told Science Daily．
   （4）       The primary point is that interdependence may bring about supportive and relationship-centered behaviors and positive perceptions of the partner - especially important in times of stress and disagreement．
   Contrary to "we-talk"，there is "I-talk"，which refers to the frequent use of the first-person singular pronouns，such as "I"， "me" and "mine"，when writing or speaking．Earlier this year，researcher analyzed a set of data that came from 47，000 people in Germany and the US．（5）       As you can see from the two studies，too much "I-talk" can make you feel depressed．But "we-talk" can encourage you to become more positive and create a chain effect of healthy interdependence with others．
   So next time you are talking to a friend，try using more "we-talk"．You may find yourself feeling more positive - and the effect it will have on your friend will be positive as well．

A．Pronouns offer an insight into whether people see themselves as individuals or as part of a whole．
B．If you are speaking in a person context，you're speaking about something that's of relevance to you．
C．Their research also found that "we-talk" is helpful for resolving conflicts．
D．Self-centered people are found to be indifferent to many things in society and other people because all their concentration is only on themselves and their needs．
E．This analysis of "we-talk" suggested that the frequent use of "we" and "us" is linked to happier and healthier relationships．
F．They found that too much "I-talk" was an accurate linguistic marker for the likelihood that someone is feeling stressed or experiencing negative emotions．
G．But seeking friends and keeping the friendship going are never easy．

204671. （2023•西安高级中学•高二下期末）     Biologists who study evolution（进化） have always been interested in animals that developed on islands.In some situations，animals on islands changed over time and came to look very different from the same species that lived on the mainland.
    The experts point to animals such as the dwarf elephant that once lived on the Mediterranean island of Cyprus.The animal is now extinct.When it lived ，however，it was only the size of a small horse.Elephants that live today in Africa and Asia are much larger than that.In the West Indies，researchers found a giant rodent（啮齿动物） that looked like a rat.However，it was about the same size as an American black bear.Rats are，of course，many times smaller than bears.
    Evolutionary experts came to call this phenomenon "island effect".They used this term to describe the fact that animals who normally have small bodies"upsize" on an island，while the opposite is true for animals who usually have large bodies.
    The"island effect"produces strange-sized animals because large animals require more food than small animals.On an island，there is a limited amount of food.As a result，larger animals become smaller over generations in order to survive with lower food intake.For small animals，there is not as much risk from predators （捕食性动物） on an island，so they often grow larger.
    Recently，researchers released their findings about 1，231 existing animals and 350 extinct ones that represent 23 million years of life.They found that animals on islands were more at risk of extinction compared to their relatives on the mainland.The arrival of human settlers increased the extinction risk for these strange animals.
    Roberto Rozzi，a paleoecologist at Martin Luther University Halle-Wittenberg in Germany said that the extinction line has become even sharper in recent decades.
    The researchers call the islands "biodiversity hotspots".Even though they only make up 7% of the Earth's land mass，they account for 20% of the land species.

（1）Why are the animals introduced in paragraph 2？
A．To compare the two species.
B．To show two kinds of rare animals.
C．To lead in the"island effect".
D．To stress the change of surroundings.
（2）What does"the opposite" refer to in paragraph 3？
A．Animals of normal small bodies"upsize" on an island.
B．Animals of normal large size have small bodies on an island.
C．Animals of normal small bodies"downsize"on an island.
D．Animals of normal large size have larger bodies on an island.
（3）Which of the following does the"island effect"agree with？
A．Some things never change.
B．The gain outweighs the loss.
C．Humans live in harmony with nature.
D．The fittest animals survive in natural selection.
（4）What is the most suitable title for the text？
A．The History of Unique Island Animals
B．The Benefits of Saving Island Animals
C．Unique Island Animals at Greater Changes
D．Biological Diversity Threatened by Humans
