Joshua Tree National Park Named for the trees native to the park,1,200-square-mile Joshua Tree National Park in California is slightly larger than the state of Rhode Island.Much of the park is wilderness and includes parts of two deserts,the higher Mojave Desert and the lower Colorado Desert.There are 12 self-guided nature trails(),some as short as a half-mile,perfect for young children. 【高二2月开学收心考试·英语第2页（共8页）】 25-L-514B Bryce Canyon(峡谷)National Park Despite its name,Bryce Canyon National Park in Utah is not a canyon at all.Instead,it is a collection of giant natural rocks up to 150 feet high.The red,orange and white colors of the rocks make for breathtaking views throughout the park.You can explore the rock formations on a scenic drive or up close and personally on a hike.

B Diego Cardenosa has loved sharks ever since he was a child.The Colombia native was never afraid of them when he visited his beloved beach.Instead,he was fascinated with how sharks moved through water using their fins().It's no surprise that he became a marine( 洋的)biologist. Concern grew as Cardenosa learned about the serious state of sharks worldwide.The International Union for the Conservation of Nature reports a shocking rise in the extinction threat to shark species,now affecting 35%,up nearly 50%in a decade.Overfishing stands as the main cause,driven by demand for shark meat and fins. "They are being killed at a rate that cannot survive in the future,"said Cardenosa."As soon as I realized they were going through a conservation crisis,I wanted to help what I love the most.” Scientists worry the sharks'dropping numbers could bring ecological disaster as they play a number of key roles in the ocean.Unlike many fish,sharks take a long time to reproduce. Fisheries kill about 100 million sharks a year,according to the non-profit Save Our Seas. Many sharks end up as bycatch when long lines and nets unintentionally catch them. Today,Cardenosa fights against the illegal shark trade as a Distinguished Postdoctoral Scholar at Florida International University.His innovation-a portable DNA kit like a small red box-plays a key role in identifying shark species and their origins in major ports globally. This breakthrough has greatly improved law enforcement()efforts in ports like Hong Kong, where the amount of seized shark fins has risen from five to a hundred tons annually since the kit's introduction. Cardenosa's efforts extend beyond sharks,aiding authorities in stopping trafficking of other endangered species like European eels and South America's matamata turtles.His commitment earned him recognition from international criminal police organization. 【高二2月开学收心考试·英语第3页（共8页）】 25-L-514B 24.What led to Diego Cardenosa's profession? A.His great interest in sharks. B.His surprise at sharks'value. C.His concern for shark extinction. D.His childhood love for oceans. 25.What is the main reason for shark species being threatened to extinction? A.Climate change. B.City construction. C.Natural disasters. D.Business fishing. 26.What could happen if sharks continue to decrease in numbers? A.There will be fewer attacks on tourists. B.More fish species might become endangered. C.Marine ecological balance could be destroyed. D.Fishing industries would face less competition. 27.What is the function of Diego's DNA kit? A.It reduces shark fin sales. B.It aids in species identification. C.It changes law enforcement. D.It meets demand for shark products. 0 We all have good days and bad days with our health,and it can be difficult when our bodies are not performing the way we want them to or need them to.But our health is not out of our power to control.As a matter of fact,we all do have a super powerful tool right in our own heads.It's our amazing brain. Researchers that study the brain-body connection have shown in numerous experiments how the brain can be tricked into believing it is getting better.A simple sugar pill()can relieve pain or even cure an illness if the person believes that the pill being taken is genuine medicine. That's how powerful our brains are.They can make physical changes in our bodies beyond what we would normally give them credit for.There is a book I reread regularly called Super Brain.The authors,Deepak Chopra and Rudolph E.Tanzi,point out that any of us can,if we choose,set up or create our own placebo()effect at any time without any kind of pill. What's super interesting,as Chopra and Tanzi explain,is that "the effect isn't limited to drugs,which is important to remember:anything you believe in can act as a placebo". They also ask where the relief comes from when the placebos are not actually doing anything themselves.They explain that it is simply "the mind telling the body to get well". The body really believes what it was being told and then it relieves the pain or heals()the sickness because it believes it can.In other words,your mind can and does influence healing of all kinds including pain,disease and wounds that our bodies deal with from time to time. That is certainly worth trying for most,if not all of us,whenever we want to cure our pain,problems or disease.These kinds of things are probably very helpful to do on a regular basis even. 28.What does the author think of the role of the brain in health? A.It's strange.B.It's powerless.C.It's fantastic. D.It's uncertain. 29.What does Super Brain suggest about placebo effects? A.They need pills. B.They're limited to drugs. C.They're always temporary. D.They can be created mentally. 【高二2月开学收心考试·英语第4页（共8页）】 25-L-514B 30.What is the key for a placebo to work according to the text? A.The degree of pain. B.The person's belief. C.The type of illness. D.The doctor's advice. 31.What does the author want to say in the text? A.Placebos are ineffective in medicine. B.Medicine is the best way to treat illness. C.Pain cannot be relieved without medicine. D.The mind influences the healing of the body. D The world's largest capital cities are seeing more extremely hot days than ever,according to a new study,which says the dangerous trend is being driven by scorching temperatures across Asia as the climate problem worsens. The world's 20 largest cities-together home to more than 300 million people-have seen a 52%jump in the number of days surpassing 35'C over the past three decades,according to an analysis by the International Institute for Environment and Development(IIED). "Climate change is not just a future threat-it's already happening and getting worse," IIED senior researcher Tucker Landesman said."In just one generation,there's been an alarming increase in the number of days of extreme heat affecting some of the world's biggest capital cities-made worse by the urban heat island effect,which occurs when cities replace natural land with roads and buildings that keep more heat." Extreme heat can be deadly,especially for groups at risk who have weaker physiological regulatory()abilities.Higher risk during heat waves can also have a very damaging impact on informal and hourly workers,who may face work stoppages or a choice between staying home unpaid or working in dangerous conditions.Heat also hurts economies, damaging crops and animals and reducing labor productivity.According to a 2022 Dartmouth College study,extreme heat has cost the global economy large amounts of dollars since the early 1990s,with the world's poorest countries bearing the force of the impact. "Responding to the challenge of extreme heat will require decisive action from policymakers, including serious investment to adapt to this new reality,"said Landesman."For many cities, it's not a lack of knowledge or capacity or resources that's preventing large-scale action to address climate change,rather it's a lack of political will and governing tools." 32.Which can best explain the underlined word "scorching"in paragraph 1? A.Slightly mild.B.Extremely hot.C.Rarely cold. D.Fairly pleasant. 33.How does the author show the extremes of heat in big cities? A.By giving an example. B.By conducting a research. C.By listing figures. D.By comparing temperatures. 34.Which of the following are most likely at risk during heat waves according to the text? A.Healthy adults. B.Tourists in a museum. C.Young children and the elderly. D.Urban planners and policymakers. 35.What is the fourth paragraph mainly about? A.The various harms caused by extreme heat. B.The effects of extreme heat on human health. C.The increasing trend of extremely hot days globally. D.The pressing need for political action on climate change. 【高二2月开学收心考试·英语第5页（共8页）】 25-L-514B 第二节（共5小题：每小题2.5分，满分12.5分） 阅读下面短文，从短文后的选项中选出可以填人空白处的最佳选项。选项中有两项为多余 选项。 Drawing is a great way to express yourself and share your creativity with others. 36 That's because you need only simple supplies.Check out these tips to make your drawing skills better.

"It looks like you've got a problem,"Derby said. "I'm afraid so,"replied the young man,who looked very worried."I'm in a big hurry, but I can't start my car!" "Is there anything I can do to help?"Derby asked. The young man looked at the two suitcases in the back seat and then said,"Thanks.If you're sure it wouldn't be too much trouble,you could help me get these suitcases to the taxi stop.I have called for a taxi and it is coming." "No trouble at all.I'd be glad to help,"Derby said. The young man took the suitcases from the back seat and handed them to Derby.After Derby walked about 100 meters,the air was suddenly filled with gun shots and sharp sounds from police cars across the streets. “Bank robbery(抢劫)！”one bystander shouted and the crowds on the street started running in all directions.

Suddenly,the crowds turned toward Derby.Feeling threatened,Derby ran even faster.
