一、现代文阅读 (35 分) .(一) 现代文阅读Ⅰ(本题共5小题，19分)阅读下面的文字，完成1~5题。

材料一：人类本质上不仅是自我中心的，而且还容易陷入社会中心的思维和行为。

群体为我们提供了安全保障，以至于我们将它们的规则、诫命以及禁忌内化了，并不加思考地遵从。

同辈群体特别容易主导我们的生活。

我们对群体价值下意识地接受，导致了无意识水平的标准：“它是真实的，因为我们相信它。

”信念似乎没有如此荒唐，但确实有一些人类群体非理性地将其当成是理性的予以接受。

我们不仅接受我们所属群体的信念体系，而且，也是最重要的，我们是按照这些信念系统行事的。

比如，很多群体从本质上是反智的，群体会期望它的成员坚持任何畸形行为。

比如，一些青年群体期望它的成员用言语和身体虐待群体外的人(以作为具有力量和勇气的证据)；而有些群体在工作周内一起分享午餐，参与传播在同一工作场所中的其他人的流言蜚语。

除了我们所处的面对面的群体之外，我们还被更大规模的社会力量间接地影响着，这些社会力量在很大程度上反映了我们社会中的成员关系。

比如，在资本主义社会，支配性的思维就是人们应该尽可能多地挣钱。

尽管这种形式的思维可能会引发争论，它鼓励着人们去接受富人与穷人之间所存在的巨大鸿沟，鼓励人们将其当成是正确的和正常的。

D．It saves you time for cooking.BPerhaps thousands of people have searched for a bronze chest full of gold and jewels hidden in the Rocky Mountains between Santa Fe and the Canadian border hidden by a millionaire adventurer. At least four people died in their search for the treasure.But it's all over now. Fenn's Treasure has been found. The 89-year-old adventurer named Forrest Fenn, who created the treasure hunt, announced the news via his website. “I don't know the person who found it, but the poem in my book led him to the precise spot,” Fenn wrote. “The treasure was confirmed by a photograph the lucky finder sent me.”Forrest Fenn, the man who started the hunt, lives in Santa Fe. He was a pilot in the Vietnam War and later accumulated his wealth as a dealer in art and antiques. Fenn was diagnosed(诊断) with cancer in 1988 and had planned to die peacefully in the woods with his treasure. But when his cancer became less serious, he changed his plan, eventually writing the poem that described his dream resting place, which is where he hid the treasure. The poem appeared in a memoir called The Thrill of the Chase. Fenn said that the chest wouldn't be found by accident; only a treasure hunter who correctly interpreted the clues(线索) would find it.Several treasure hunters went missing while attempting to find the chest, including hunter Jeff Murphy and Mike Petersen, both of whom went missing in Yellowstone National Park in 2017. Fenn said that he had never been to the Yellowstone National Park, and that the treasure was not in a dangerous place. "It was in thethick forest of the Rocky Mountains and had not been moved from the spot where I hid it more than 10 years ago," Fenn wrote on his website. It is illegal to remove anything from a national park, which would cause trouble in legally claiming the treasure if it was found there.4．What contributed to the finding of the treasure?A．Fenn's announcement. B．A poem in Fenn's book.C．Fenn’s vivid description.D．A photo on Fenn's website.5．What is the third paragraph mainly about?A．Who Forrest Fenn was. B．Where Fenn hid the treasure.C．How the treasure hunt began. D．What Fenn did to find the treasure.6．What can we learn about "Fenn's Treasure”?A．It was in Yellowstone National Park.B．It was found by someone by chance.C．It was moved from one place to another.D．It was in Fenn's chosen resting place.7．What does the underlined word “claiming” in the last paragraph probably mean?A．Taking. B．Burying. C．Protecting. D．Acknowledging.CNot buying things can be difficult, even when you're determined not to. For many people, a no-buy year is simply a way of life because their financial situation leaves them no other choice. But for others—myself included—we have enough clothes, shoes, electronic devices, books, and so on. Yet, we continue to buy.If you're going to try a no-buy year, the first step is identifying why you're doing it. Is it to save money? Pay off debt? Have more money for experiences? To be more sustainable? Without a goal, failure is likely. I say this based on my experience.Last year, I wanted to take my sons on vacation where I could afford the rental and good meals. So I set a goal. That goal was not to buy anything I didn't need. A month before we went, I realized I needed to do more.I decided that I wouldn't spend money going out socially. I eventually reached my goal.After vacation, I went back to my regular spending habits. But I wonder what would have happened if I'd maintained the stricter habits. There are many experiences I would love to have—concerts and music festivals are at the top of the list. Yet, I often buy little things—like $20 shoes instead of tickets to concerts. If I could forgo those little things, I would probably go to a lot more concerts.I think the no-buy movement is something that would bring us some happiness. Still, it's difficult. Eventhough we're surrounded by things, we manage to convince ourselves that none of those things are the “perfect” things for our immediate need.I'm going to set another goal right now. That goal is to go to a big music festival at the end of the summer. To get there, I promise I won't spend money on the things I don't really need. Nowadays, I encourage you to spend some time thinking about what your goals are and how about buying nothing—or at least buying a lot less—can help you reach them.8．Why did the author not continue her social activities?A．To pay off her debt. B．To accompany her sons.C．To realize her sons' goals. D．To save money for their vacation.9．What does the underlined word “forgo” mean in Paragraph 4?A．Quit. B．Afford.C．Maintain. D．Rent.10．What does the author think of the no-buy movement?A．It is beneficial but hard to carry out.B．It shows the true meaning of happiness.C．It finds fault with current spending habits.D．It gives way to big music festivals and musicals.11．What would the best title probably be?A．The No- Buy Movement Is PopularB．Could You Handle A No-Buy Year?C．Financial Situation Affects What We Can BuyD．Do What You Like Even If You May Meet TroubleDThe area around Taal Lake on Luzon Island in the Philippines is known for its natural beauty. Tourism is popular there as travelers go there to see the scenery that surrounds Taal Volcano, one of the most active volcanoes in the country. It was quiet for years until January 12, 2020 when the volcano erupted. Since then, the cities surrounding the volcano have been covered with ash and many people are forced to leave home.But the ash didn't stop the residents of Binan, a city that is 35 km south of Manilla, from finding a way to help their neighbors in the towns that suffered the most from Taal. Binan Mayor Walfredo Dimaguila ordered the city residents to collect the ash and to put it in sacks (麻袋) to be sent to the state-owned factory that can produce 5,000 bricks a day to turn it into bricks to use for rebuilding damaged communities.“What we plan is to turn them into hollow blocks and bricks and sell them to interested companies,” Dimaguila said. But he noted, the money would be donated to the people directly affected by the volcano. “When Batangas (the region where Taal is located) is in recovery, the bricks can not only be used to build schools, community halls and livelihood centers but also help deal with ash pollution for the earth,” Dimaguila said. “The misfortune of our neighbors in Batangas is there. Let's transform this into opportunity.”The Philippines, located in the Pacific “Ring of Fire: zone of fire” and part of the typhoon belt, is a country that is known for natural disasters like earthquakes, volcanic eruptions, and major storms. But the Filipino people show their strong will and community spirit.12．What has happened to Taal Volcano?A．It attracts more and more visitors. B．It becomes quieter and quieter.C．It is covered with ash completely. D．It causes bad effects on the locals.13．What are people advised to do according to Walfredo Dimaguila?A．To collect volcanic ash for recycling. B．To save sacks for factories to use.C．To set up a factory for making bricks. D．To build communities for people from disasters. 14．What can we infer from Dimaguila's words in Paragraph 3?A．Companies are expected to donate money.B．Bricks made of volcanic ash are popular.C．Batangas has been the most misfortune.D．Turning ash into bricks benefits the earth.15．What's the main idea of the passage?A．Taal Lake on Luzon Island is destroyed. B．Taal Volcano has enjoyed popularity.C．Disasters always hit the Philippines. D．The Filipino people turn ash into treasure.第二节(共5小题；每小题2.5分, 满分12.5分)根据短文内容, 从短文后的选项中选出能填入空白处的最佳选项。
