专项突破·阅读理解C/D篇主旨80题
Passage 1
[1] Fr decades, scientists have assumed that memry frmatin is a gradual prcess, requiring repeated expsure t infrmatin. Hwever, a grundbreaking study frm MIT challenges this lng-held belief.
[2] The research team, led by Dr. Sarah Jhnsn, cnducted experiments n mice using advanced imaging techniques. They discvered that a single, intense experience can create a lasting memry if it triggers a specific chemical reactin in the brain. This reactin, invlving the prtein CaMKII, acts as a "memry switch."
[3] "We fund that when the prtein is activated at a high enugh level, it can cnslidate a memry instantly," explains Dr. Jhnsn. "This ges against the traditinal view that repetitin is essential." The findings suggest that the brain has a built-in mechanism fr "ne-trial learning," which may have evlutinary advantages—helping animals remember a single dangerus encunter.
[4] Critics pint ut that the study was cnducted n mice, and human brains are far mre cmplex. Nevertheless, the research pens up new pssibilities fr treating memry disrders. If scientists can learn t cntrl this "memry switch," it culd lead t therapies fr cnditins like PTSD, where a single traumatic event creates an verwhelming memry. Cnversely, it might help thse with Alzheimer's strengthen fading memries.
[5] Dr. Jhnsn's team is nw planning clinical trials n humans. "This is just the beginning," she says. "We are excited abut the ptential t revlutinize hw we understand and treat memry." The future f memry science, it seems, may be abut quality ver quantity.

Passage 2
[1] In recent years, the cncept f "digital minimalism" has gained tractin amng tech users. The idea is simple: reduce screen time and fcus n meaningful activities. But is this just a passing trend, r des it reflect a deeper shift in hw we relate t technlgy?
[2] A recent survey by the Pew Research Center reveals that 65% f American adults have tried t limit their scial media use. The reasns vary: sme cite mental health cncerns, while thers feel that nline platfrms are a waste f time. Interestingly, yunger generatins—Gen Z and millennials—are leading this mvement.
[3] Hwever, experts warn that simply cutting back n screen time may nt be enugh. Dr. Mark Williams, a scilgist at Stanfrd University, argues that the prblem is nt technlgy itself, but hw we use it. "We need t cultivate digital literacy," he says. "Instead f blaming the tl, we shuld learn t use it mindfully."
[4] This perspective shifts the fcus frm quantity t quality. It's nt abut hw many hurs we spend nline, but what we d during thse hurs. Fr instance, using scial media t cnnect with lved nes r learn new skills can be beneficial, while mindless scrlling is harmful.
[5] Sme cmpanies are already respnding t this shift. Tech giants like Apple and Ggle have intrduced screen time tracking features, and new apps prmting fcused wrk are emerging. Yet, Dr. Williams cautins that these tls are nly part f the slutin. "Ultimately, it's abut persnal respnsibility," he says.
[6] The mvement twards digital minimalism reflects a brader scietal awakening. As we becme mre aware f technlgy's impact, we are learning t take cntrl. The gal is nt t abandn technlgy, but t integrate it int ur lives in a way that enhances well-being.
21. What is the main idea f the passage?

Passage 3
[1] Climate change is ften discussed in terms f rising temperatures and extreme weather. Hwever, a less visible but equally alarming cnsequence is cean acidificatin. As the cean absrbs mre carbn dixide, its chemistry changes, with devastating effects n marine life.
[2] Since the Industrial Revlutin, the cean has absrbed abut 30% f the CO2 released by human activities. This has led t a 30% increase in cean acidity. Fr rganisms like crals, shellfish, and planktn, this is catastrphic. Their calcium carbnate shells disslve in acidic water.
[3] "We are seeing the effects already," says marine bilgist Dr. Elena Trres. "In sme regins, yster larvae are struggling t frm shells. This threatens the entire seafd industry." But the impact ges beynd individual species. Cral reefs, which supprt a quarter f all marine life, are bleaching and dying.
[4] Sme argue that the slutin lies in technlgy—fr example, adding alkaline substances t the cean t neutralize acid. Hwever, Dr. Trres warns that such geengineering appraches are risky and unprven. "The nly real slutin is t reduce CO2 emissins at the surce," she insists.
[5] Internatinal effrts like the Paris Agreement aim t limit glbal warming, but current pledges are insufficient. Withut immediate actin, cean acidificatin will accelerate, disrupting fd chains and ecnmies. The windw t act is clsing.
[6] Yet, there is hpe. Public awareness is grwing, and sme cuntries are implementing stricter emissins plicies. Individuals can als help by reducing their carbn ftprint. As Dr. Trres puts it, "Every tn f CO2 avided is a victry fr the cean."

Passage 4
[1] Fr centuries, humans have relied n intuitin t make decisins. Frm chsing a career t selecting a life partner, we ften trust ur gut feelings. But is intuitin always reliable? Recent research in behaviral psychlgy suggests that while intuitin can be useful, it is ften biased and leads t errrs.
[2] A series f experiments cnducted by Dr. Emily Carter at Yale University revealed that peple's intuitive judgments are heavily influenced by recent experiences and emtins. Fr example, after watching a sad mvie, participants were mre likely t predict negative utcmes in hypthetical scenaris. This phenmenn, knwn as "affective frecasting," shws hw emtins clud ur intuitin.
[3] Hwever, Dr. Carter emphasizes that intuitin is nt always harmful. In situatins where we have extensive expertise, such as a chess master making a quick mve, intuitin can be remarkably accurate. The key, she says, is t knw when t trust it and when t questin it.
[4] The implicatins f this research are far-reaching. In fields like medicine and law, where decisins have life-r-death cnsequences, relying slely n intuitin can be dangerus. Dr. Carter advcates fr a balanced apprach: cmbine intuitive judgments with analytical thinking.
[5] Sme critics argue that the research versimplifies the cmplexity f human decisin-making. They pint ut that intuitin is shaped by culture, upbringing, and persnal values, which are difficult t measure in a lab. Nevertheless, the findings challenge the rmanticized view f intuitin as an infallible guide.
[6] S, the next time yu make a snap decisin, pause and ask yurself: Is my intuitin based n expertise, r is it a prduct f my md? By becming mre aware f ur biases, we can make wiser chices. After all, as Dr. Carter puts it, "Intuitin is a tl, nt a master."
61. What is the main idea f the passage?
A. Intuitin is always reliable. B. Intuitin can be useful but is ften biased.
C. Emtins have n effect n decisin-making. D. Experts shuld never use intuitin.
62. The wrd "intuitin" in paragraph 1 mst prbably means ______.

一线教学提示： 引导学生先读首尾段，找出主旨句；再关注文中转折词（but, hwever等），这些后面往往是作者真正观点。训练学生快速定位主旨，避免被细节干扰。每篇完成后，可让学生用一句话概括全文大意，强化主旨意识。
