2024届江苏省兴化中学高三高考综合演练（二）英语试题一、阅读理解King's College Summer School is an annual training program for high school students at all levels who want to improve their English. Courses are given by the teachers of King's College and other colleges in New York. Trips to museums and culture centers are also organized. This year's summer school will be from 25 July to 15 August.More information is as follows：1．Which of the following is TRUE about King's College Summer School?A．Only top students can take part in the program.B．King's College Summer School is run every other year.C．Visits to museums and culture centers are part of the program.D．Only the teachers of King's College give courses.2．How much will you pay the school if you are to attend the program but live with your relatives in New York?A．＄200.B．＄400.C．＄500.D．＄900.3．What information can you get from the text?A．The program will last two months.B．You can write to Thompson only in English.C．As a Chinese student, you can send your application on 14 July, 2022.D．You can get in touch with the school by e­mail or by telephone.In high school I was very shy, content to hang around with my small group of friends and to concentrate on my courses. I was quickly labeled a "brain." I did so well that by the end of senior year I had perfect grades and enough college credits to give up an entire quarter of coursework.But in early June of senior year, the principal called me into his office. He asked me to give a speech at graduation. I was surprised to look at him, my heart thumping. This was the reward for my hard work? I murmured something and fled the office, blaming myself for staying away from physics, a subject sure to have broken up my perfect record.I finally agreed to a compromise. I would share the honor with five other students. I agreed to introduce my friend Judy, who would then give her own, full-length speech.Graduation day soon arrived, I’d been practicing my speech for days, and I had it memorized. The first half hour of the ceremony passed in a blur, and then my moment came. My name was announced. I managed to reach the stage without falling down. I faced my classmates. My voice trembled a little, but mostly it was clear and strong. But within seconds, I was done and heading back to my seat. I accomplished something I’d never dreamed of — I spoke in front of hundreds of people.Although I didn’t realize it at the time, the successful completion of that speech gave me the confidence to take part in class at college, to give oral reports, and to eventually break free of my shyness. I never would have chosen to give a speech at graduation — or ever. But I’m glad I did. Ino longer hesitate when I’m faced with the prospect of doing something I feared. I know it may very well turn out to be one of my shining moments.4．Why was the writer called a "brain"?A．She was the most intelligent student.B．She was the head of her small group.C．She was a bookworm all the time.D．She did more coursework for good grades.5．What can we learn from the second paragraph?A．She ruined her health by studying hard.B．She got the reward as was expected.C．She was grateful for giving a speech.D．She wasn't good at physics at school.6．How did the author feel at the beginning of the graduation speech?A．Excited.B．Moved.C．Scared.D．Embarrassed7．What did the speech bring to the author at last?A．She had nothing to fear in life,B．She won enough college credits.C．She got rid of her sense of shyness.D．She desired to become a speaker.On average, American kids ages 3 to 12 spent 29 hours a week in school, eight hours more than they did in 1981. They also did more household work and participated in more of such organized activities as soccer and ballet. Involvement in sports, in particular, rose almost 50% from 1981 to 1997: boys now spend an average of four hours a week playing sports; girls log hall that time. All in all, however, children’s leisure time dropped from 40% of the day in 1981 to 25%.“Children are affected by the same time crunch that affects their parents,” says Sandra Hofferth, who headed the recent study of children’s timetable. A chief reason, she says, is that more mothers are working outside the home. (Nevertheless, children in both double-income and “male breadwinner” households spent comparable amounts of time interacting with their parents19 hours and 22 hours respectively. In contrast, children spent only 9 hours with their single mothers.)All work and no play could make for some very messed-up kids. “Play is the most powerful way a child explores the world and learns about himself,” says T. Berry Brazelton, professor at Harvard Medical School Unstructured play encourages independent thinking and allows the young to negotiate their relationships with their peers, but kids ages 3 to 12 spent only 12 hours a week engaged in it.The children sampled spent a quarter of their rapidly decreasing “free time” watching television. But that, believe it or not, was one of the findings parents might regard as good news. If they’re spending less time in front of the TV set, however, kids aren’t replacing it with reading. Despite efforts to get kids more interested in books, the children spent just over an hour a week reading. Let’s face it, who’s got the time?8．What does the underlined phrase “the same time crunch” in Paragraph 2 refer to?A．Children have little time to play with their parents.B．Both parents and children suffer from lack of leisure time.C．Children are not taken good care of by their working parents.D．Both parents and children have trouble managing their time.9．In the author’s opinion, a child develops better if .A．he has plenty of time reading and studying B．he is free to interact with his working parentsC．he is left to play with his peers in his own way D．he has more time participating in school activities10．What does the author worry about American kids?A．They are increasingly ignored by their working mothers.B．They are engaged in more and more structured activities.C．They are spending more and more time watching TV.D．They are involved less and less in household work.11．What can we conclude from the text?A．Extracurricular activities promote children’s intelligence.B．Most parents believe reading to be beneficial to children.C．Efforts to get kids interested in reading have been fruitful.D．Most children will turn to reading with TV sets switched off.Move over, helicopter parents. “Snowplow (扫雪机) parents” are the newest reflection of an intensive (强化的) parenting style that can include parents booking their adult children haircuts, texting their college kids to wake them up so they don’t sleep through a test, and even calling their kids’ employers.Helicopter parenting, the practice of wandering anxiously near one’s children, monitoring their every activity, is so 20th century. Some rich mothers and fathers now are more like snowplows: machines moving ahead, clearing any difficulties in their children’s path to success, so they don’t have to suffer failure, frustration (挫折) or lose opportunities.It starts early, when parents get on wait lists for excellent preschools before their babies are born and try to make sure their kids never do anything that may frustrate them. It gets more intense when school starts: running forgotten homework to school or calling a coach to request that their children make the team.Rich parents may have more time and money to devote to making sure their children don’t ever meet with failure, but it’s not only rich parents practicing snowplow parenting. This intensive parenting has become the most welcome way to raise children, regardless of income, education, or race.Yes, it’s a parent’s job to support the children, and to use their adult wisdom to prepare for the future when their children aren’t mature enough to do so. That’s why parents hide certain toys from babies to avoid getting angry or take away a teenager’s car keys until he finishes his college applications.But snowplow parents can take it too far, some experts say. If children have never faced a difficulty, what happens when they get into the real world?“Solving problems, taking risks and overcoming frustration are key life skills,” many child development experts say, “and if parents don’t let their children experience failure, the children don’t acquire them.”12．What do we know about snowplow parenting?A．It appeared before helicopter parenting.B．It costs parents less than helicopter parenting.C．It was a typical phenomenon of the 20th century.D．It provides more than enough services for children.13．What is mainly discussed about snowplow parenting in Paragraph 4?A．Its cost.B．Its benefits.C．Its popularity.D．Its ending. 14．Why does the author mention parents’ taking away car keys?A．To show teenagers are no better than babies.B．To advise teenagers not to treat their cars as toys.C．To advise parents not to buy cars for their teenagers.D．To show it’s appropriate to help children when necessary.15．What’s the possible result of snowplow parenting according to the experts?A．Children lacking problem-solving ability in reality.B．Children mastering more key life skills than parents.C．Children gaining great success in every aspect of life.D．Children meeting no problems or frustration after growing up.Capture spirit of youth“Youth is like the early spring，like the morning sun，like the budding flowers，like the sharp blade fresh off the grinding stone. Youth is the most valuable time of life. "Chen Duxiu，one of the founders of the Communist Party of China，once wrote the Spirit of Youth.16 During this time，habits and interests that will continue for the rest of your life are formed and developed--so it's important to get off to a good start.But what is the spirit of youth It's a time to begin the process of self-reliance and self-motivation.

Only you can be the author of your own life.When times get tough，please be persevering. Train yourself to be strong. Tell yourself that you can summon（召唤）the will to overcome whatever obstacles come your way. Anything worth doing isn't easy. 18 In the end，conquering a difficult task is always worth it，and you canthank perseverance for guiding you there.Work hard.

新疆的艾比湖面积约1200平方公里，是新疆第一大湖。

博尔塔拉河、精河、奎屯河及其他大大小小的河流，最终都投入了它博大的怀抱。

这汇集而来的河川之水，将天山和戈壁滩的大量盐分，①。

同时，炎热干旱的准噶尔气候和阿拉山口的强风，②。

久而久之，艾比湖之水也就变成了矿化度极高、含盐量超过30%、比海水高出近10倍的极浓咸水。

因此，艾比湖区盛产青盐和红盐。

湖中芒硝含量也极为丰富，还有着含量不可低估的钾、硫、镁、碘、硼、溴等矿物元素。

艾比湖是一个③。

蓝色波涛，绿色芦荡，多彩多姿的各类水鸟，把艾比湖装点得风光无限。

湖之东、南离湖不远的地方，又有着上百平方公里的野生树林，树林里有比人还高的红柳，需数人围抱的胡杨，还有梭梭、芨芨草和紫罗兰等五彩纷呈的野花。

这些树木和野花与四周荒凉单调的沙漠戈壁，共同形成了艾比湖区独特的景色。

1．请在文中横线处补写恰当的语句，使整段文字语意完整连贯，内容贴切，逻辑严密，每处不超过12个字。

2．文中画波浪线处使用了何种修辞手法？请简要分析其表达效果。

【答案】1．①都聚积在这辽阔的湖里②使湖水蒸发升腾很快（或使湖水很快蒸发升腾或加快湖水蒸发升腾的速度）③风光诱人、生机盎然的湖泊2．①文中画波浪线句子使用了拟人的修辞手法。

②语句既赋予艾比湖人的形象，又将博尔塔河、精河、奎屯河及其他大大小小的河流最终都汇聚到艾比湖的过程人格化，赋予它们人的动作；③既使表达更加生动、形象、具体，又表达了作者对艾比湖的喜爱之情。

【分析】1．本题考查学生语言表达之情境补写的能力。
