2023届四川省绵阳市高三第二次诊断性考试英语试题(含答案解析)

2023届四川省绵阳市高三第二次诊断性考试英语试题学校:___________姓名:___________班级:___________考号:___________一、阅读理解The following list focuses on the top4not-to-be-missed world-class museums,helping tourists explore and experience the best the New York City has to offer.COOPER HEWITT,SMITHSONIAN DESIGN MUSEUMThe Cooper Hewitt,Smithsonian Design Museum(CHSDM)was founded in1897.It is the only museum in the U.S.devoted to historic and contemporary design.Exhibitions feature more than650objects throughout four floors of the building,many of which draw from the museum’s permanent collection of more than210,000objects.Free guided tours are provided from11:30AM to1:30PM on weekdays and1PM to3PM on weekends.MUSEUM OF THE MOVING IMAGEThe Museum of the Moving Image(MOMI)is housed on the original13-acre lot that made up the historic Kaufman Astoria Studios.Lose yourself in the permanent exhibit, Behind the Screen,which introduces visitors to the history of the moving image from19th-century optical(视觉的)toys to today’s digital tools used to edit and produce films.AMERICAN MUSEUM OF NATURAL HISTORYOne of the world’s largest natural history museums with more than33million exhibits, the AMNH educates and entertains visitors,keeping them busy for hours on end.The museum offers self-guided tours,including one featuring exhibits from the movie,Night at the Museum with Ben Stiller.There are a handful of places to eat inside should the kids get hungry.The kid sleepovers at the AMNH are impressive.NEW-YORK HISTORICAL SOCIETYThe New-York Historical Society(NYHS)was founded in1804as New York’s first museum.The Henry Luce II Center for the Study of American Culture on the fourth floor has been redesigned to showcase The Gallery of Tiffany lamps,displayed in a glass gallery.The Center for Women’s History is the first of its kind in a U.S.museum devoted to this subject.It offers free daily tours at2and3:30PM.1.When can you get free guided tours at the CHSDM?A.At12:30PM Monday.B.At2:30PM Thursday.C.At10:30AM Saturday.D.At11:30AM Sunday.2.Which museum provides special care for children?A.CHSDM B.MOMI.C.AMNH.D.NYHS. 3.What is special about NYHS?A.It has the longest history.B.It focuses on human history.C.It provides free tours all day long.D.It tells the history of the moving image.What are the most sustainable crops to grow for food security?Perhaps,in your growing zones,oranges or peaches win for best fruit crop.Hot,dry climates might call for dates or grapes.For me,growing organic apples is the best.Perhaps that’s because my hometown knows more about growing and preserving apples than any other fruit.Some apples may have worms in them.“It’s not that bad.It’s organic.Just cut the worm out.”I laugh even as I type this.For us,“organic”is how we grow apples,but it does mean carving good fruit away from black worm holes.Modern techniques for growing organic apples include worm traps,fruit barriers,and organic insecticides,like bacterial poisons that only target worms.Wormy apples are just fine for apple juice and jam,Mom says.Cut off the good part and throw it in the pot.Throw the bad part to the chickens.Boil the fruit and put juice into canning jars.Apple jam become pancake topping and the replacement“oil”in recipes—that is,if we don’t eat it directly out of the jar.Apples are now so symbolic to American life that other countries try out the market.When I was younger,I might have laughed at that because of how connected apples and American stories have become,despite the fact that apples aren’t native to North America.But a good friend,after visiting several farms in his motherland Nigeria,showed me photos of Nigerian apples.The skin texture(质地)and color resembled American apples,but they were shaped more like oxheart tomatoes.So even though apples have taken on symbolic significance in America,they can contribute to food security in all kinds of places. 4.What’s the passage mainly about?A.Organic food and modern techniques.B.American and African apples.C.Climate and growing crops.D.Apples and food security.5.What happens to the good parts of wormy apples?A.They are thrown away.B.They are made into apple juice. C.They are sold to customers.D.They are fed to the chickens. 6.What does the author learn from his friend?A.Apples are not native to North America.B.Other countries are also growing apples.C.Apples outside America are ugly-looking.D.People of other countries don’t like apples.7.What can be inferred from the passage?A.America produces the best apples of the world.B.Poisons are no longer used on apples in America.C.The author is proud of apples grown in his hometown.D.Apple juice and jam are actually made from wormy apples.Kjell Inge Roekke is a billionaire owner of an oil company from Norway.As a young man,he was a high school dropout who moved to the US to become an ordinary fisherman. Now he is the tenth-richest man in his country.Worth two billion dollars,he plans to give much of his money away and is starting with cleaning up our oceans.In the Pacific Ocean, there is an island called the Great Pacific Garbage Patch,which is twice the size of the continental United States.It consists of nothing but small pieces of plastic and the dead bodies of sea life and birds.The billionaire is buying a state-of-the-art ship.With the latest equipment on board,the ship will remove five tons of plastic from our oceans daily.Kjell started his business empire building industrial fishing boats.He believes he owes his fortune to the ocean and wants to pay the debt back.“I want to give back to society the majority of what I’ve earned.This ship is a part of it.”said the seagoing man.Managed by the conservation organization WWF,the ship’s mission is to get the poisonous things out of the oceans.It couldn’t come at a better time.Earlier this year a killer whale washed up on a UK shore was poisoned by man-made chemicals.The whale called Lulu was the most poisoned on record.It was20years old and had never reproduced because her body had been badly damaged.Kjell has given WWF complete control of the boat.The conservation organization is not comfortable with the practices of the Norwegian’s oil business.Yet in the struggle to save the environment,unlikely partners must work together.Without the world’s oceans,life on Earth wouldn’t exist.8.What has Kjell decided to do?A.Make our oceans clean again.B.Put an end to his oil business.C.Stop using plastics in his daily life.D.Remove the rubbish with his own hands.9.What does“state-of-the-art”in Paragraph4probably mean?A.Beautiful.B.Advanced.C.Expensive.D.Comfortable. 10.Why is Lulu the whale mentioned in the passage?A.To ask people to help the creature.B.To invite people to join in the effort.C.To stress the consequence of the pollution.D.To draw attention to the Great Pacific Garbage Patch.11.Why does WWF decide to work with Kjell?A.Ocean pollution calls for combined action.B.It is comfortable to work with a billionaire.C.His business is friendly to the environment.D.He has given up control of his newly bought ship.If you are forgetful or make mistakes when in a hurry,a new study from Michigan State University(MSU)found that meditation(冥想)could help you to become less likely to make mistakes.The research,published in Brain Sciences,tested how open monitoring meditation (OMM)changed brain activity in a way that suggests increased error recognition.The findings suggest that different forms of meditation can have different effects.“Some forms of meditation have you focus on a single object,commonly your breath,but OMM is a bit different,”Lin said.“It has you pay attention to everything going on in your mind and body. The goal is to sit quietly and pay close attention to where the mind travels without getting too caught up in the scenery.”Lin and his MSU co-authors—William Eckerle,Ling Peng and Jason Moser—employed more than200participants to test how OMM affected how people detect and respond to errors.The participants,who had never meditated before,were taken through a 20-minute OMM exercise while the researchers measured brain activity through EEG(脑电图).While the meditators didn’t have immediate improvements to actual task performance, the researchers’findings offer a promising window into the potential of sustained meditation.“These findings are a strong demonstration of what just20minutes of meditation can do to enhance the brain’s ability to detect and pay attention to mistakes,”Moser said.“It makes us feel more confident in what meditation might really be capable of for performance and daily functioning right there in the moment.”Looking ahead,Lin said,“The next phase of research will determine whether changes in brain activity can translate to behavioral changes with more long-term practice.It’s great to see the public’s enthusiasm for meditation,but there’s still plenty of work from a scientific viewpoint to be done to understand the benefits it can have,and equally importantly,how it actually works.”12.How does OMM differ from other forms of mediation?A.It fixes your focus on your breath.B.It keeps your mind and body calm.C.It makes you caught up in the scenery.D.It enables you to be aware of everything.13.What does the results of the research show?A.The mediators acquire the habit of meditating regularly.B.The mediators can improve their ability to recognize errors.C.Meditation has an immediate influence on task performance.D.Meditation can increase people’s confidence about themselves.14.What will the research team try to find out next?A.How to monitor brain activity.B.How to sustain meditation practice.C.Meditation’s influence on behavior.D.The public’s response to meditation.15.What can be a suitable title for the text?A.Meditation Helps People Sit QuietlyB.OMM Helps Measure People’s Brain ActivityC.Brain Activity Improves People’s PerformanceD.Meditation May Help People Make Fewer Mistakes二、七选五Everyone at some time feels that their life is going nowhere-and fast.____16____ Nothing can beat living an active,purposeful,successful

中华优秀传统法律文化是中华优秀传统文化的重要组成部分。
发掘中华优秀传统法律文化的深厚底蕴,是赓续中华文脉,建设中华民族现代文明的重要途径,也是汲取传统智慧,建设社会主义法治国家的有力支撑。
我国古代治国理政最为重要的“治国之具”是礼与法。
古人对礼法关系及其在治国理政中的作用进行了概括。
如《唐律疏议》中载“德礼为政教之本,刑罚为政教之用”。
德礼,即道德,更多的是人心由内而外发挥的“善”,而刑罚乃是为了“为善去恶”而生的必要的“恶”。
《唐律疏议》认为道德的缺陷在于难以形成统一的秩序,法律则弥补了这一不足,保证了外在秩序的稳定。
以道德礼义为本,以法律政刑为用,凸显了传统法律文化对“治国之具”的准确定位。
春秋战国时期出现的“礼崩乐坏”局面,使得思想家普遍意识到“法治”的重要性。
《艺文类聚》中载“治国无其法则乱”。
“法治”最为突出的要件就是“立法为公,一断于法”。
而实现公正、平等,要立有良法,且良法能得到妥当施行。
晋朝尚书刘颂曾建言:“律法断罪,皆当以法律令正文,若无正文,依附名例断之,其正文名例所不及,皆勿论。
”其建议后成为晋律的内容。
在晋律影响下,后世确立了依法断罪的制度。
至唐朝,《唐律疏议》规定,“诸断罪皆须具引律、令、格、式正文,违者笞三十”,这对于限制司法专横具有重要意义。
在具引法典条文前提下,还强调罚当其罪,而非一味机械地征引。
