四川省大数据学考大联盟2023-2024学年高二下期期末模拟质量检测英语试题
四川省大数据学考大联盟2023-2024学年高二下期期末模拟质量检测英语试题一、阅读理解Life is full of people telling you what to do. Reading is a world that belongs to you, inside your own head. Reading for pleasure is so much more than simply “filling up your eyes with words”. It’s about finding a book you love.Loki: Tales of a Bad GodBy Louie StowellThe Loki series stars a naughty trickster-god (欺诈之神), sent to Earth as an ordinary schoolboy, who records his amusingly crazy adventures in a diary. This special Loki book tells several new stories and is the perfect pick for fans of funny fictions.Can You Get Jellyfish in Space?By Dr Sheil a KananiYou might have heard of dogs going into space — but what about cats and jellyfish? This fantastic book is full of wild and surprising facts about space. It’s the ideal choice for anyone fascinated by things beyond Earth.Onyeka and the Secret SuperheroBy Tolá OkogwuTwelve-year-old Onyeka is a pupil at the Academy of the Sun — a school for young superheroes, who are known as Solari. She’s sent on a mission to investigate some strange weather events.Dread Wood: Creepy CreationsBy Jennifer KillickAngelo and his friends at Dread Wood High school have already faced terrifying monsters. In this thrilling mission, they braved the darkness and danger into the tunnels beneath the school to rescue their teacher.1.What is Loki: Tales of a Bad God mainly about?A.A special mission of rescuing a teacher.B.Fascinating stories of animals in space.C.An investigation of odd weather events.D.New stories of funny crazy adventures.2.Which can be the perfect pick for science-lovers?A.Loki: Tales of a Bad God B.Can You Get Jellyfish in Space?C.Onyeka and the Secret Superhero D.Dread Wood: Creepy Creations3.What is the shared topic of the last two books?A.Terrifying monsters.B.Strange weather.C.Students’ special mission.D.Students’schoolwork.I felt panicked when my wife and I decided to adopt a child. I expected joy and excitement, but I had to face a series of “what if’s”.What if the child isn’t anything like me? It’s natural for parents to look for their reflection in their children and live their lives indirectly through their children’ success. But I knew it might be a good thing not to place my ego (自我) on the child, who doesn’t share my genes.But what if I don’t love this child? How could I just decide to love a stranger? But as we got physical examinations, did interviews, filled out forms, and talked to lawyers, he didn’t seem like a stranger when I first met him three days after his birth. With one arm gently holding his whole body, I looked into his eyes and knew that my heart belonged to him.But what if he later asks about who he is and why he is adopted? This was not a “what if” I could completely work through in advance. But since our adoption was open and we had met his birth parents, I decided to keep a written record of the whole adopting process, including the joy and love he has brought to us. If he is full of questions and confusion when he is sixteen, I hope to hand him this record.Of course, other “what if’s” that threatened to decrease our love and courage may come. But all of them can be answered or overcome. And we did adopt this child whom I wouldn’t trade for anything in the world. And this new world of fatherhood has become my heart’s true home. 4.What can be inferred from paragraph 2?A.Parents wish their children to like them.B.Parents always fail to achieve their goals.C.The child doesn’t share the author’s genes.D.The author won’t force his self-worth on the child.5.Why did the author want to keep a written record?A.To clear up the son’s doubts of his origin.B.To show the difficulty of the adopting process.C.To emphasize his deep love for the adopted son.D.To avoid potential problems from his son’s birth parents.6.What is the author’s attitude towards those “what if’s”?A.Doubtful.B.Positive.C.Unconcerned.D.Negative. 7.What is this passage mainly about?A.A suggestion about adopting a perfect child.B.A prediction of problems before being a father.C.A road of overcoming difficulties to fatherhood.D.A record of complex process of adopting a child.Some school uniforms could be preventing young students from being physically active, research suggests.There is a WHO’s minimum recommendation of 60 minutes of physical activity a day across a whole week. In countries where most schools require students to wear uniforms, fewer young students reach that standard, especially girls. They have a gap of 7.6 percentage points with boys, according to a study by the University of Cambridge.This gap between girls and boys of primary-school age is greater than that between secondary-school girls and boys. Because younger children may get more unintentional exercise throughout the day — like running, climbing and active play at break and lunchtimes. The findings confirm earlier evidence — that girls feel less comfortable participating in active play if they are wearing certain types of clothing such as skirts or dresses.A 2021 study in England found students were deterred from participating in certain activities by the design of girls’ uniforms. Other studies have suggested girls are more uneasy about engaging in physical activity, because they are wearing uniforms in which they do not feel comfortable. Dr Esther van Sluijs, senior author and MRC investigator said, “Girls might feel lessconfident about doing certain sports if they are wearing a skirt or dress. Social norms (规范) and expectations tend to influence their thoughts — what they can do or cannot do in these clothes.Unfortunately, when it comes to promoting physical health, that’s a problem.”Dr Mairead Ryan, a researcher at Cambridge said, “Schools often prefer to use uniforms for various reasons. We are not trying to suggest an overall ban on them, but to present new evidence to support decision-making. School communities could reconsider the design, which might restrict any opportunities for physical activity throughout the day.”8.Who are most probably affected by uniforms?A.Primary-school girls.B.Primary-school boys.C.Secondary-school girls.D.Secondary-school boys.9.What did previous studies indicate?A.Girls have severe health problems.B.Girls don’t like taking physical exercise.C.Girls feel uncomfortable exercising in skirts.D.Girls don’t respect the social norms of dressing.10.What does the underlined word “deterred” most probably mean in paragraph 4?A.Disqualified.B.Discouraged.C.Protected.D.Excused. 11.What is the probable purpose of this passage?A.To criticize the quality of school uniforms.B.To encourage students to do physical activities.C.To call on students not to wear school uniforms.D.To suggest changing the design of school uniforms.Between 245 and 66 million years ago, dinosaurs ruled the land. Some groups of dinosaurs developed to be able to fly, but experts thought they never truly swam — apart from walking in shallow water. However, dinosaur bones that were discovered in Africa have now challenged this theory.The bones came from a group of dinosaurs called hadrosaurids (鸭嘴龙). Scientists describe them as “duck-billed” because their mouths and noses were shaped a bit like ducks’ bills (喙). They first appeared in North America during a period known as the late Cretaceous —between 100million and 66 million years ago. They eventually spread into Europe and Asia, which were connected to North America at that time.However, scientists were very puzzled by the bones appearing in Africa. Today, Africa is connected to Asia due to the land movement. But in the Cretaceous period, Africa was then a huge island separated from Asia and Europe by sea. So how did the hadrosaurids get there, across hundreds of miles of water, millions of years ago?According to a new scientific study, the bones they found — from a skull, an arm and a leg — came from three species, one smaller and two larger. In fact, scientists think the skull belongs to an entirely new duck-billed species, named Minqaria bata (咪龙). This was between three and four meters long and was about the size of a pony. The scientists say their body structure was similar to European duck-billed dinosaurs.The study says the only possible conclusion is that the duck-billed dinosaurs must have swum or floated to Africa. Dr. Nicholas Longrich, one of the authors, said, “The Cretaceous lasted nearly100 million years. A lot of strange things would happen in that time — including dinosaurs crossing seas.” Dr. Longrich described the hadrosaurids in Africa as the “most surprising find” of his career. He said a duck-billed dinosaur was “the last thing” he would have imagined finding in Africa.12.What did experts believe about dinosaurs before finding the bones?A.They had no ability to swim.B.They had power to rule the world.C.They had existed for 100 million years.D.They had a similar appearance to ducks. 13.What confused the scientists about hadrosaurids?A.The origin of species.B.The difference in size.C.The means of migrating.D.The complexity of structure.14.What did Dr. Longrich mean in the last paragraph?A.He would no longer study dinosaurs.B.Strange things happened to dinosaurs.C.Nothing else could be found in Africa.D.He hadn’t expected to find such dinosaur. 15.Which can be the best title for the text?A.Dinosaurs Swam to Africa B.Dinosaurs Ruled the LandC.The Cretaceous Time Was Strange D.New Duck-billed Species Were FoundSoon to be a senior three student and feeling anxious? For many students, stepping into senior three can arouse feelings of anxiety and stress. The fear of tests, lack of sleep and difficulty in concentration often stop you from fully putting into study. 16 . Here are some practical tips to help you overcome it and create a positive experience for yourself.Take breaks while studying. Although you should study as much as you need to, it is possible to overdo it. Spending every minute of the day studying will damage your nerves and make anxiety worse. Every hour or two, you should take a break for 10 minutes or more. 17 .Stay active. Exercise and physical activity are great ways to reduce anxiety. Physical activity releases endorphins (内啡肽) that will lift up your mood. 18 , so your brain will havea chance to relax and refresh itself.19 . Sometimes, the symptoms of anxiety can be so severe that they affect your everyday life. If you find that you experience anxiety symptoms on a regular basis, don’t be afraid to ask for help. Talking to your parents, teachers, and friends can be a great resource to get your anxiety under control. If you have extreme anxiety, see a professional doctor.20 . Although it won’t go away overnight, facing and dealing with it will help you learn stress management, which will boost your confidence and benefit your overall mental health. A.Talk to someoneB.Seek help if you need itC.This way, you can find the best way to overcome your anxietyD.It will also distract your mind from the negative thoughts and stressE.However, with effective strategies, you can conquer senior three anxietyF.This will set you at ease and you can come back to your studies refreshedG.Everything takes time and practice, and learning to beat anxiety is no different二、完形填空On Sept.17, 2022, a father and a son completed their first marathon in Cambridge, Maryland.
