Because of his condition, he began using a wheelchair at age 4. His mother, Sandy Gilbreath, raised him as a single parent. Although taking care of a child with a disability was challenging, she ensured that Cory didn't miss out on the fun things in life. Sandy took him on road trips during summer breaks throughout his childhood. The exciting experiences of exploring new places inspired him to set a lifelong goal of visiting all seven continents.Fortunately, Cory was able to do that just before the COVID-19 started. He and his mother traveled to Antarctica in February, just before the borders closed. It was the seventhand final continent off his list. He became the first-ever wheelchair user to visit all the seven continents!According to Cory, traveling in a wheelchair requires a wide range of planning and research. He starts his research six to twelve months before each trip, making sure that there are accessible transportation options in the location. He would also call up hotels or rental homes to confirm if they are truly as accessible as they claim to be.When Cory started going on adventures, there weren't many online resources discussing accessible travel. To help other travelers with disabilities explore the world as he does, he decided to share his knowledge in his blog. Aiming to promote representation of the wheelchair-using community, Cory and his mother wrote a children's book, titled Let's Explore with Cor Cor, which is about a boy who travels around the world in his powered wheelchair.^Traveling to all seven continents wasn't something I was sure was going to be possible," he said. "But if you stay determined and keep a positive attitude, the opportunities are limitless."4. What made Cory Lee decide to visit all seven continents?A. His mother's expectation.B. His travelling experiences.C. His dream of helping others.D. His objective of making a history.5. What worries Cory most about a trip?A. Rental fees.B. Local attractions.C. Accommodation.D. Transportation.6. Why did Cory and his mother write the book?A. To enrich online resources.B. To record travelling events.C. To help people with special needs.D. To introduce wheelchair adventures.7. What can we learn from Cory's story?A. Nothing can prevent a determined heart.B. Disability can turn into an opportunity,C. Travelling shapes a positive attitude.D. Mom is the creator of children's dreams.CDo you like the woolly mammoths （长毛象）from the movie Ice Age? Too bad they're extinct? Thanks to recent developments in biotechnology, the stuff of science fiction may soon become a reality through an attractive process called "de — extinction", which aims to bring the extinct species back. The resurrected （复活的）species are functionally equal to the original extinct species, but they are not exact copies.There are three primary techniques of de — extinction. One of them is that scientists deliberately select existing species with similar characters to the extinct species to produce later generation. This is a natural method. Another is cloning. A cloned animal is created by obtaining the DNA of the extinct animal. The later generation will be an identical copy of the extinct species. This is only applied to animals that are either endangered or have recently gone extinct, as it requires well-preserved eggs. The third is the newest technique, genetic （基因）engineering. It uses gene-editing tools to place selected genes from extinct animals in place of those present in its closest living relative.If we refer to Jurassic Park , resurrecting extinct animals is a terrible idea. Thankfully, we don't have to worry about dinosaurs running wildly, as their DNA has disintegrated over the 65 million years since their extinction. DNA can survive for several million years at best under certain rare conditions, but does that mean we should do that?De —extinction is more for ecology than for tourism. Ecologist Ben Novak said, “All animals perform critical roles in their ecosystem. Woolly mammoths, for example, were excellent gardeners. Their disappearance was followed by a loss in diversity and the Arctic grassland became a cold, ice field. If a resurrected animal is always going to be a zoo animal then it shouldn't be brought back.”8. Why does the author mention the movie Ice Age ?A. To recall the joy from the movie.B. To lead the audience into the topic.C. To attract readers, attention to the movie.D. To show functions of resurrecting animals.9. What is mainly discussed about de — extinction in Paragraph 2?A. Its main methods.B. Its wide application.C. Its complex procedures.D. Its distinct characteristic.10. What can replace the underlined word “disintegrated“ in Paragraph 3 ?A. Broken away.B. Picked up.C. Fallen apart.D. Run out.11. What would be the best title for the text?A. Can we bring extinct animals back?B. Do you like the woolly mammoths?C. Will dinosaurs be seen in the zoos?D. Should we promote cloning skills?DWe already know that salt can lead to heart disease. But could it also affect our mind? Scientists found that a high-salt diet caused cognitive impairments （认知损伤）in mice» and it could produce the same effect on humans.Costantino Iadecola， director of the Feil Family Brain and Mind Research the Institute, said they fed the mice eight to sixteen times their normal salt intake and then tested the mice. After about three months, the mice had a big change in their behavior. Mice are very curious, and they like to look for new things. However, the tested mice lost the ability to identify a normal object. When the mice were put in their cage and asked to find a quiet spot,they did not remember where the quiet spot was. Then when the mice were building a nest, which is something the mice do daily, they, were unable to do so. The research suggested humans would experience a similar response.Studies have shown Australians eat around double the recommended amount of salt each day, most of it coming from processed food. Dr ladecola said the estimated two teaspoons of salt the average Australian eats each day could affect the brain function in the long term. However, the decline might not be as obvious as in the mice, who were given extremely high levels of salt. "But probably over years and perhaps decades - as opposed to a few months for the mouse - even lower levels of salt may have a terrible effect," Dr ladecolasaid.“High levels of salt cause serious immune （免疫）changes in the organs in and around the stomach, resulting in an almost autoimmune effect on the brain. It is part of a growing body of evidence that we really are what we eat,“ Bryce Vissel, director o f the Centre for Neuroscience at the University of Technology Sydney, said. "Those changes in turn cause all sorts of responses in the body, which over time certainly contribute to cognitive impairments."12. Which can describe the tested mice?A. They remained quiet all day.B. They became smarter than ever.C. They forgot some routine things.D. They were quick at finding objects.13. What do we know about Australians?A. They ignore health advice.B. They have a higher-salt diet.C. They dislike processed food.D. They value their brain health.14. What does the last paragraph mainly focus on?A. Studies carried out by Bryce Vissel.B. Immune changes brought about by salt.C. Effects of daily diets on human behaviors.D. Links between salt intake and brain damage.15. What does the text suggest?A. Brain health counts much.B. The body never tells a lie.C. Low-salt diet is to be advocated.D. Heart diseases can be prevented.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。

After that, I felt more relieved. “Thanks to your timely care, I feel much better,” I said gratefully to the nurse. “It is you that I should express my sincere thanks to actually. Remember the struggling mother many years ago?” she asked. Amazed and surprised, I recognized she was the young lady who had been interviewed by me. “How did you make it?” I asked, wondering how she pursued her dream.“You never know what impact your encouraging words had on me,” the nurse said. She told me that she was determined to achieve her goal following my advice.

So fantastic was this encounter. How blessed we were to have met each other! What could be more rewarding than to help someone fulfill their dreams. Helping others will benefit yourself as well.。

As an old saying goes, we make a living by what we get, but make a life by what we give.I truly believe that a job is definitely not a job if you love what you arc doing. Many years ago, I worked in an employment and insurance office, which helps people find jobs, apply for employment and insurance, and return to school for training. What could be more rewarding than to help someone find a job or change their career?I have always said that people are at （heir worst when they are unemployed or sick. I must admit that some days were challenging. But I have one amazing story that I would like to share.One day, a lady came to the office with a dream to become a registered nurse. According to my client, her family did not approve. She was a mother with young children, and her husband had returned to school for （raining. Il was not economically practical fbr her to return to school.It was clear that this lady had a passion for the nursing profession, so I encouraged her to realize her dream. I equipped her with （he information necessary to apply for nursing school, and she left the office. She went on her way, and 1 never knew whether she followed her drcam or not.Many years later, I was diagnosed（诊断）with cancer of the stomach and was admitted to the hospital fbr an operation. I must admit I was scared. My mother had died of cancer at age forty. I had a husband and two beautiful children. I was only fbrty-eight years old. The surgery was successful. It was, however, very painful. Days flew smoothly as I recovered from the pain. 注意：1.续写词数应为150词左右；2.请按如下格式作答。

As we all know, in daily life, many people want to get in shape. If you happen to be one of them, where will you get started?Diet comes first. 16 Health experts have long noted the importance of physical activities.17 Physical activity burns calories-the more calories you consume, the easier it is to control or lose your weight. Besides, it helps to reduce the risk of some diseases, including heart disease, stroke and even some kinds of cancer.Physical activity is also known to increase the release of endorphins （内啡肽）, which help people to reduce pain and feel more happy and peaceful as well. 18 Some experts believe it's the act of exercising itself. Others say it's the feeling one gets from having met an exercise goal. Either way, the two things work together when it comes to improving one's emotional health.So exactly how much exercise do you need to do to gain all of these great health effects? Different people, different ideas. Experts say it is easier than you think-one activity is better than none. 19To get the most from your exercise plan, you are advised to choose physical activities that you find fun. 20 What you really like, sometimes, outweighs what is popular among the public.A. It helps to guarantee that you can stay with the program.B. Keeping a balanced diet contributes a lot to your health.C. You can release some bad emotions by physical activities.D. Exercise is a good way for you to maintain physical health.E. So, if you are not doing anything, now is the time to get started.F. There is some debate about exactly what causes the release of them.G. However, diet alone won't do much good without an exercise plan.16—20 GDFEA山东省潍坊市2020-2021学年高三上学期期末试题英语试题第二节（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入空白处的最佳选项。

Here are some things you should try before you are 18.★Learn to swimSeriously, this is so important that it can save your life. If you can’t swim well, you won’t be able to dowater sports like waterskiing, surfing and diving. Even taking a boat trip will be dangerous for you. Make sure you do it.★Try at least one kind of team sportsBeing a good team player is an important skill in life. You can’t just think of yourself, but have to work well with other people. Other advantages of team sports like basketball, football and baseball are that they keep you fit and healthy, and they are also great fun. Teams usually have a good social life too—you’ll go to lots of parties and make many friends.★Collect somethingOne of the best hobbies for under-18s is collecting things. You could collect kinds of stamps, or you could collect things that make you remember what you have done, like cinema tickets for films you have seen or letters from friends. The best way to collect is to have a special album to put your collection in and to write what each thing means to you. That way you won’t forget.1. The most important reason for learning to swim is that ________.A. you might feel wellB. it can make you healthyC. you might easily do lots of thingsD. it can save your life2. The writer tells us that one of the best hobbies is to ________ .A. collect somethingB. do some water sportsC. send letters to your friendsD. play basketball with your friends23. The passage is mainly about ________before you are 18.A. good habits to keepB. skills to haveC. things to doD. sports to playBA former UPS driver and his wife have made history by donating $20 million to Morgan State University – the largest gift any historically black college or university (HBCU) has ever received from a former student. The money, pledged by Calvin Tyler Jr and his wife Tina, will fund scholarships that were established under the Tylers’ name in 2002.Tyler grew up in a low-income family and was forced to drop out of Morgan State University in 1963 because he could no longer afford to study. The following year, Tyler saw a job advertisement in a Baltimore newspaper from United Parcel Service and got a job with the company as a driver. He rose through the ranks during his 34-year career at the global shipping company to become its senior vice president of US operations and a member of the board of directors before retiring in 1998.Tyler and his wife, also a Baltimore native, have lived all across the country but he said they have never forgotten their humble beginnings.Their latest pledge follows a $5million commitment they made in 2016 for the fund, which to date has supported 222 students with full or partial scholarships.Marybeth Gasman, a professor at Rutgers University who studies HBCUs, said the gift is significant because public HBCU’s like Morgan State University tend to have a lower alumni giving rate compared to private ones.“For a long time, they weren’t asking alumni to give,” she said. But that has changed in the past couple of decades, she added, and the schools have “started asking alumni to give and creating a culture of philanthropy (慈善) on campus.”David K. Wilson, the president of Morgan State University, said the money will help students for years to come. “Morgan is so proud to call this son and daughter of the great city of Baltimore our own,” he said in a statement. “Through their historic giving, the doors of higher education will most certainly be kept open for generations of aspiring leaders whose financial shortfalls may have kept them from realizing their academic dreams.”“We are forever indebted to the Tylers”.4. Why is Tyler’s donation historic?A. He was a former UPS driver.B. The donation is large enough.C. The donation will fund his scholarships.D. He used to be a student at the university.5. What is a driving force of Tyler’s donation?A. His working experiences.B. His career achievements.C. His promise to the university.D. His past embarrassing situations.6. Which is true about HBCUs according to Gasman?A. They are mainly public universities.B. They are encouraging alumni to donate.C. They rarely accept help from the alumni.D. They have changed little over the decades.7. What can be inferred about Tyler from Wilson’s comments?A. He’s helped many city leaders.B. He’s grateful to his university.C. He’s made great contributions.D. He’s proud of his son and daughter.CA student had to get his long hair cut off in a middle school in GuangDong Province. It was talked a lot among teachers and students.In fact, all schools have their own rules. In most schools, boy students are not allowed to have long hair while girls are not allowed to dye their hair. And most school rules say that students should wear their school uniforms at school. And students must obey these rules so that they can get healthy development at school.But some students have disagreements. They think that boy students having long hair doesn't mean that they are not good students. They want to show their own personality. They think that they would look cool too if they had long hair and the hairstyles like their favorite stars.A girl student thought that she would look much more beautiful if she had brown hair. So she had her dark hair dyed brown one day. When she went back to school the next day, the teacher was very angry with her. She said that she worked hard at her lessons and did well in every subject. She just didn't know why the teacher didn't allow her to dye her hair while women teachers can.It is not wrong for teenagers to love stars' hairstyles or wear their favorite clothes. However, a school has its own rules for all the students to obey so that the school can be in good order. Students should not break the rules at school.8. What aren't boy students allowed to do in most middle schools according to this passage?A. To have long hair.B. To wear uniforms.C. To like famous stars.D. To show their own personalities.9. Why did the girl make her hair brown?A. Because she wanted to be cool.B. Because she thought that she would look much more beautiful.C. Because she wanted to make her teacher angry.D Because women teachers dyed their hair.10. What does the writer think of these school rules?A. The students should be against them.B. They are bad for students.C. They can make schools in good order.D. They can't make students grow healthily.11. What is the passage mainly about?A. Hair styles and clothes.B. Schoolboys and schoolgirls.C. Students and famous stars.D. School rules.DJennifer Mauer has needed more willpower than the typical college student to pursue her goal of earning a nursing degree. That willpower bore fruit when Jennifer graduated from University of Wisconsin-Eau Claire and became the first in her large family to earn a bachelor's(学士) degree.Jennifer grew up on a farm in a family of 10 children. Her dad worked at a job away from the farm, and her mother ran the farm with the kids. After high school, Jennifer attended a local technical college, working to pay her tuition(学费), because there was no extra money set aside for a college education. After graduation, she worked to help her sisters and brothers pay for their schooling.Jennifer now is married and has three children of her own. She decided to go back to college to advance her career and to be able to better support her family while doing something she loves: nursing.
