A．Chinese Language Performance Competition.B．The Chinese Corner.C．The Chinese Host Family Program. D．Language Partner Program.3．The passage is intended for ________.A．American senior high students B．American university students C．Chinese senior high students D．Chinese university StudentsI drove a taxi for extra money east of Toronto thirty years ago. Each time a taxi drove up to the front of the Greenwood Racetrack, a group of local kids would run along the sidewalk angling for position by the passenger door. One lucky kid, or rather, the most aggressive one, would open the passenger door and say “Good luck, Mister!” The man getting out of the cab would vaguely say thanks and throw the kid a quarter. It was a routine everybody knew.Throughout the summer, one kid caught my eye. He was bigger than most of all the other kids but pushed away by even the smallest. He never made it but never gave up. One day, his chance arrived. As I was pulling up to the sidewalk, all the kids were pushing for a cab just ahead of mine. The boy saw me and walked toward my taxi. As I positioned the passenger door right beside him, he never paused and opened the passenger door, warmly saying, “Good luck, Mister!”But the man neither said thanks nor flipped him a quarter. He pushed him aside so hard that the boy fell on the sidewalk. I knew it hurt him badly. I got out in less than 10 seconds, but the man was gone in the crowd. So I looked for the kid. I decided to give him $20 for the effort. By the time I spotted him he was far up ahead, walking away in the opposite direction through the crowd and his head hanging down. When I got the cab turned around I lost sight of him. I never saw him again. I’d like to find him one day and tell him that if only he had stuck arounda little longer I would have given him a whole $20.I learned from this kid that when things seem so hopeless that you are ready to give up, it’s the time when things are most likely to turn around for you.4．What can we learn from the first paragraph?A．The passenger was ready to give a tip to the kid.B．The author was a professional taxi driver at that time.C．The lucky child was the toughest among the local kids.D．The driver would work with and benefit from those children.5．Why did the kid never succeed in opening the passenger door?A．He was modest. B．He was the shortest.C．He made no effort. D．He pushed his way.6．Why did the author get out of his taxi?A．To catch up with the kid.B．To encourage the disappointed kid.C．To give the kid some money.D．To intend to demand the tip for the kid.7．According to the passage, which goes with the author’s intention?A．Never give in to difficulties. B．Sunshine comes after a storm. C．Face up to competitions. D．Each road leads to Rome.Sure, chocolate is a delicious treat, and it’s a staple of some of our favorite desserts. But it’s not a health food, so it should be enjoyed in moderation-right?Well, it turns out that eating chocolate might actually have a pretty significant health benefit. According to research conducted by five scientists in Italy, compounds found in chocolate, called flavanols, can help boost cognitive (认知的) performance. Yup, chocolate’s good for your brain.The scientists, studying at the Universities of Rome and L’A quila, summarized research from ten different studies. The studies assessed people’s performance on cognitive tests before and after eating cocoa or chocolate. The results were pretty telling: in nine out of the ten studies, there was a noticeable improvement after the subjects had eaten the chocolate. The scientists found improvements in “general cognition, attention, processing speed and working memory.” Sounds pretty good to us!And that’s not all. In subjects, especially women, who performed the tests w hilesleep-deprived, the flavanols helped relieve the negative effects of the sleep deprivation. And there’s even more good news. The researchers also found that eating chocolate daily (over periods ranging from five days to three months) produced noticeable long-term improvements in cognition. Older adults, whose memories were already declining, saw an especially significant improvement.All chocolate has flavanols, since they occur naturally in cocoa. However, dark chocolate lovers feel happy, because it has more flavanols than any other type of chocolate. In fact, the scientists themselves have claimed that, after doing this research, they’ve started eating dark chocolate every day!Now, we’re not saying you should start eating chocolate for breakfast, lunch and dinner - it’s still high in sugar and low in nutrients. But next time you find yourself yawning after a sleepless night, snack on some chocolate and let the flavanols work their magic.8．What does the underlined phrase in Paragraph 1 probably mean?A．As much as possible. B．For three meals.C．In right amount. D．Not in the least.9．How does a student perform while learning after eating chocolate?A．He memorizes less than before.B．He can’t concentrate on lessons in the slightest.C．He becomes more excited.D．He understands what the teacher says faster.10．According to the passage, if your memory fails, what should you do?A．Eat chocolate as three meals. B．Use chocolate as a daily snack. C．Hunt for dark chocolate. D．Ask a doctor for advice.11．What’s the main idea of the passage?A．Chocolate is a beneficial but unhealthy food.B．Eating chocolate benefits our learning.C．Eating chocolate works on your sleep.D．Chocolate contains low nutrients.The British custom of driving on the left side of the road isn’t a sign of eccentricity—there’s actually a very sensible reason for it.Originally, almost everybody travelled on the left side of the road. For Medieval swordsmen on horseback, it made sense to keep to the left to have their right arms closer to their opponents. Mounting and dismounting horses were also easier from the left side, and safer done by the side of the road than in the center.So perhaps the question here should be, why did people stop travelling on the left?Things changed in the late 1700s when large carriages pulled by several pairs of horses were used to transport farm products in France and the United States. In the absence of a driver’s seat inside the carriage, the driver sat on the rear left horse, with his right arm free to use his whip to keep the horses moving. Since he was sitting on the left, he wanted other vehicles to pass on his left, so he kept to the right side of the road.The British Government refused to give up their left-hand driving ways. Meanwhile post-revolution France, under their left-handed ruler Napoleon, stuck to a permanent move to the right side of the road. As the British and the French were yielding their power across the globe, they insisted that the countries they occupied drive like them. This explains why former British colonies such as Australia, New Zealand and India drive on the left, while former French colonies like Algeria drive on the right.When Henry Ford made his Model T in 1908, the driver’s seat was on the left, meaning that for Americans, cars would have to drive on the right side of the road to allow front and back passengers to exit the car onto the sideway. This influenced a change in many countries, such as Canada, Italy and Spain. However, British drivers remain on the left, and this is highly unlikely to change.12．It can be inferred from Paragraph 2 that in Middle Ages ________.A．people always got on horses from the left sideB．people all walked and rode on the left of the roadC．people never got off horses in the center of the roadD．swordsmen felt safer travelling on the left of the road13．Why did people start travelling on the right?A．They used large carriages to transport farm products.B．They had to hold their whips with their right hands.C．They wanted other carriages to pass on their left.D．They were forced to sit on the back left horse.14．According to the passage, which of the following keep to the left side of the road?A．Russia. B．India.C．Spain. D．Algeria.15．Why does the author mention Model T in the last paragraph?A．To introduce a world-famous make of American cars.B．To stress its role in changing the custom of driving.C．To describe its safest design for passengers.D．To explain why the British won’t change.二、七选五Asking for a raise can be a discouraging prospect for any employee. 16．If you’re a female employee seeking a raise, it matters to approach that conversation strategically. Here are a few tips for pulling it off successfully.Do your research.17．So if y ou’re making a case for a pay increase, you’ll need to gather some data on what others in similar positions are earning. To that end, do some research on sites like . 18．Remember to collect the average earnings for all workers in your position and make your case for why you deserve to be paid similarly.Don’t get emotional.Women are often accused of getting emotional on the job. In fact, it’s that so-called sensitive nature that causes some people to claim they’re uncomfortable working with and promoting female employees. That’s why it’s extremely important to keep you cool during a salary negotiation. Be specific and present hard evidence of your value to the company. Try to focus on your positive contributions, rather than the negative feelings. And although the discussion might get heated, be sure not to yell or, worse yet, cry while it’s going down. 19．20．Given many news stories about how men out-earn women, you may tend to draw on some of that data as a reason for getting a raise. But be very careful about using that argument, because unless you have definitive proof that your male colleagues - with the same exact titles, experience, and responsibilities —are making more money than you, you’re better off avoiding that angle.A．Don’t accuse y our employer.B．Staying calm will only help your case.C．Take advantage of how much men colleagues earn.D．It’s never a good idea to go into a salary negotiation blindly.E.You are often paid less salary than your workmates in similar positions.F.But women face unique challenges when it comes to requesting more money.G.They allow you to search for compensation info based on industry and geographic region.三、完形填空When Benjamin was born, he looked different from other babies. The doctors told my parents he had Down syndrome. I was 21 at the time, so I wasn’t sure what it was, but I knew it wasn’t 22 . I also knew that I finally had the baby brother I 23 , even if he wasn’t perfect. The doctors said Ben might need help doing 24 things such as walking, talking, eating and 25 with people. I was told that I would need to be extra careful with Ben, and that I might someday have to 26 for him and protect him. Of course, 27 of these warnings bothered me; I knew from the second I laid 28 on him that I loved him.As Ben and I got older, we were always together. After Benjamin learned to 29 , we wanted to get him to jump, run and move around. 30 Ben preferred to follow my 31 , his therapist or Mom would have me do the exercise first, and then Ben would try to do it. 32 me was Ben’s way of saying he loved me.A few years ago, I went away with some friends for the day. Sitting in the bus, we started talking about our siblings (兄弟姊妹). My friends were saying how stupid and annoying33 siblings were. I hadn’t said anything; I was just listening in 34 . I had never thought there were brothers and sisters tha t just didn’t 35 . Suddenly I said, “I love my brother.” I said “love”36 because it was true.There are no 37 thoughts in my head when I hear people making fun of Ben. I go right up to them and explain that Ben has Down syndrome, that his life isn’t as easy for him as it is for us, and that if you give Ben a 38 he’ll be the best he can be at 39 you want him to be.I think Ben is 40 just the way he is. I will always love Ben, and he will always love me, no matter what.21．A．curious B．little C．scared D．weak 22．A．good B．serious C．real D．rare 23．A．hated B．wanted C．defended D．envied24．A．special B．interesting C．simple D．dangerous 25．A．interacting B．fighting C．competing D．arguing 26．A．look out B．work out C．turn up D．stand up 27．A．none B．one C．some D．all 28．A．head B．eyes C．heart D．hands 29．A．speak B．sit C．eat D．walk 30．A．Though B．If C．While D．Since 31．A．lead B．advice C．rules D．instructions 32．A．Kissing B．Following C．Greeting D．Serving 33．A．my B．our C．your D．their 34．A．panic B．peace C．astonishment D．joy 35．A．keep in contact B．behave well C．get along D．grow up 36．A．angrily B．proudly C．bravely D．gently 37．A．such B．enough C．practical D．second 38．A．smile B．job C．chance D．hug 39．A．whatever B．whichever C．whoever D．whenever 40．A．healthy B．mistaken C．perfect D．unfortunate四、用单词的适当形式完成短文One of the main 41．(challenge) many international students face is their English-language proficiency.

四川省成都市2023-2024学年高一上学期1月期末英语试题学校:___________姓名：___________班级：___________考号：___________一、阅读理解Sport plays a huge part in Australian culture. Here are some wonderful sporting events1．Which event will tennis fans be interested in?A．Australian Open.B．Melbourne Cup.C．Uluru Camel Cup.D．World Surfing Championships.2．In which month can we enjoy two different sporting events?A．January.B．March.C．May.D．November. 3．What’s special about Melbourne Cup?A．It provides food.B．It is a public holiday.C．It lasts for a weekend.D．It has live performances.I grew up with the same group of kids from age 5 to age 12. We lived in the same community, shared the same schools and experienced all the ups and downs of that period.Then I hit junior high and a whole new world opened up to me. It seemed everyone was there, friends from football teams and people from the summer workshop. They welcomed me, figuring that I had to be cool to know so many people. I was a different person with each new group of friends and began to distance myself from the “kindergarten group”.However, it wasn’t long before these so-called new friends left me when they found out I really wasn’t cool enough to be there. This was one of the hardest times in my life. I felt alone and was very disappointed in myself. It was then, when I thought I had nowhere else to go, that I tried to make my way back into the “kindergarten group”. I organized a camp-out and invited them to come. I had thought they were going to be cold and exclude me as I had done to them. But they all turned up and we just picked up right where we left off. There was absolutely no hate, only comfort and an unexpected sense of belonging. They gave me room to grow and learn my own lessons, my own way, in my own time.From them, I have learned two things: the type of friends I want, and the type of friend I want to be. We will all continue to grow separately together, all the while providing the unconditional love, understanding and support only friends like these are capable of. 4．How did the author feel about her school life according to Paragraph 2?A．Shocked.B．Upset.C．Curious.D．Happy. 5．Why did the author organize a camp-out?A．To make more friends.B．To get close to nature.C．To apologize to her friends.D．To reconnect with her old friends.6．What does the underlined word “exclude” in Paragraph 3 probably mean?A．Cheat.B．Refuse.C．Warn.D．Attack. 7．What can be a suitable title for the text?A．A Friend in Need.B．My Kindergarten Group.C．Lessons in Friendship.D．Friends in My New School.My brother Jack’s childhood was completely influenced by his extreme picky eating. From three to about 14, he only ate chicken, peanut butter, apples, cereal, and sweets. We tried everything in the book, but none succeeded.However, in the past three years, he has gone through an amazing change. Today, he will eat close to ten times the types of foods he was willing to try before. He is even willing to try new things; he constantly asks to order something different at a restaurant. I’ve often wondered what makes a person change so much.Through some research, several factors come out. The first major player in our food preferences is innate (先天的), and it all starts with genetics. As humans, we all are likely to enjoy a few particular tastes for evolutionary (进化的) reasons.However, genetics aren’t the only factor that explains why we enjoy or dislike particular foods. In fact, most of our preferences are actually learned, sometimes even before we are born. In one study, mothers regularly drank carrot juice late in the stages of their pregnancy (怀孕). After birth, these babies tended to enjoy carrot-flavored milk more than other babies.Additionally, I believe that sometimes, cultural influences affect your willingness to try food, Possibly, my brother finally got so sick of having to be the one who needed a special order at a restaurant that he forced himself to try and like those things he was afraid of. It simply takes time. People will learn to adapt and realize their true tastes. An open mind is a positive thing, and most will develop an ever-expanding plate as they age.8．What do we know about Jack’s eating habit before he was 14?A．He always ate too much.B．He only ate certain foods.C．He had no chance to try new food.D．His family changed his eating habits.9．Which word can best describe Jack’s change of eating habits?A．Surprising.B．Scary.C．Dangerous.D．Funny. 10．What does the study on pregnant mothers tell us?A．Our food preference can be learned.B．Genetics influences food preference.C．Eating habits can’t be changed very easily.D．People enjoy certain foods for evolutionary reasons.11．What suggestion does the author make about eating habits?A．Keep a healthy lifestyle.B．Stick to what we like.C．Understand the food culture.D．Stay open and try something new.The Gezhouba Dam is the world’s largest run-of-river hydropower (水力发电) station and the first large water control project in the Yangtze River. It will celebrate the 43rd anniversary (周年纪念) of its functioning in 2024. Since its functioning, nearly 600 billion kilowatt-hours of electricity has been produced in total. It is the largest water protection project independently designed, constructed and operated by China in the 20 century.From the start of construction in 1970 to the functioning of the first generator unit in1981, to the completion of the whole project in December 1988, more than 100,000 hydropower specialists from all over the country, who set up base in the wilderness, carrying poles and pushing carts to overcome a series of significant technical problems, finally completed all the construction tasks with their blood and sweat.Since its completion, the Gezhouba Dam has safely released more than 60 floods equal to 45,000 cubic meters per second on the Yangtze River, effectively reducing the pressure of downstream flood control operations and helping to protect the lives and belongings of people in the middle and lower reaches of the Yangtze.“The successful construction and management of the Gezhouba Dam has provided valuable experience and played a role in training talent for the design, construction and operation of the Three Gorges Project and other super dams. Practice has proved that the Chinese are able to build and manage large water projects on the Yangtze River,” Xiang Ke, deputy director of the Gezhouba Hydropower Plant, said, “A new chapter of hydropower development for the Chinese people begins with the Gezhouba Dam, and we will continue our efforts to contribute to a brighter future in this field.”12．What can we learn about the Gezhouba Dam?A．It started to function in 1991.B．It is the world’s largest water control project.C．Its completion is achieved without any foreign help.D．It produces about 600 billion kilowatt-hours of electricity annually.13．How long did the construction of the Gezhouba Dam take?A．7 years.B．11 years.C．18 years.D．43 years. 14．What is introduced about the Gezhouba Dam in the last paragraph?A．The process of building it.B．The way to operate it.C．The reasons for constructing it.D．The significance it has produced.15．What is the purpose of the text?A．To introduce a famous hydropower station.B．To explain the function of the Gezhouba Dam.C．To present China’s determination in flood control.D．To stress the importance of water control projects.We can study language change using language corpora (语料库) like the Cambridge English Corpus, which contains a large collection of texts gathered over many years. 16 Changes in adverbial meaning. A large change in language that we recorded in our research is the change in terms of frequency (频率) of the adverb “literally”, which in the 2010s was almost ten times more frequent than in the 1990s, for example. 17 There has also been a notable change in meaning with the 2010s seeing much more metaphorical (比喻的) use of literally than before e.g. “oh I literally haven’t moved all day”. This is important, as if someone had not moved in the slightest for a whole day, then we might grow a little worried for them. This of course was not what the speaker meant. 18Technology.Creativity in language often assumes creativity in the wider world. and technology is a great driver of this. Think about companies like WeChat or WhatsApp. which were founded in 2011 and 2009 respectively. In 2007, if you were to say “I’ll whatsapp you”, no one would have understood. 19 In fact, in the Now Corpus there are no examples of the word WhatsApp in 2010, while in 2018 there were over 50,000 examples.20 The word “wicked”, for example, was originally used as a negative word. Buta study shows that in spoken British English, wicked is used more positively like “well wicked” in the 2010s, An important thing to know is that if someone calls something wicked. it is not necessarily bad.A．Changes in positive and negative words.B．Changes in the position of words in a sentence.C．Rather, the speaker was most likely to stress a fact.D．Here are three findings from the study of such data.E．However, frequency is not the only point of interest.F．Fortunately language change is happening all around us.G．But now the frequency of the word has increased sharply.二、完形填空It was freezing cold last Saturday morning.

When he arrived on the scene, he didn’t27．A．looked into B．turned to C．took in D．cared for 28．A．warm B．energetic C．relaxed D．peaceful 29．A．medicine B．food C．clothes D．toys 30．A．lovely B．poor C．lost D．injured 31．A．pleasure B．determination C．fear D．shame 32．A．thanked B．interviewed C．influenced D．found 33．A．escaped B．panicked C．fought D．hid 34．A．annoyed B．embarrassed C．worried D．disappointed 35．A．plan B．intention C．arrangement D．effort三、语法填空阅读下面短文, 在空白处填入1 个适当的单词或括号内单词的正确形式。

表示1台机器在购买易损零件上所需的费用(单位：元)，n 表示购机的同时购买的易损零件数．(1)若n ＝19，求y 与x 的函数解析式；(2)若要求“需更换的易损零件数不大于n ”的频率不小于0.5，求n 的最小值；(3)假设这100台机器在购机的同时每台都购买19个易损零件，或每台都购买20个易损零件，分别计算这100台机器在购买易损零件上所需费用的平均数，以此作为决策依据，购买1台机器的同时应购买19个还是20个易损零件？19．解：(1)当x ≤19时，y ＝3800；当x >19时，y ＝3800＋500(x －19)＝500x －5700.所以y 与x 的函数解析式为y ＝⎩⎪⎨⎪⎧3800，x ≤19，500x －5700，x >19(x ∈N )． (2)由柱状图知，需更换的零件数不大于18的频率为0.46，不大于19的频率为0.7，故n 的最小值为19.(3)若每台机器在购机同时都购买19个易损零件，则这100台机器中有70台在购买易损零件上的费用为3800元，20台的费用为4300元，10台的费用为4800元，因此这100台机器在购买易损零件上所需费用的平均数为1100×(3800×70＋4300×20＋4800×10)＝4000(元)．若每台机器在购机同时都购买20个易损零件，则这100台机器中有90台在购买易损零件上的费用为4000元，10台的费用为4500元，因此这100台机器在购买易损零件上所需费用的平均数为1100×(4000×90＋4500×10)＝4050(元)．比较两个平均数可知，购买1台机器的同时应购买19个易损零件．20.（本小题满分12分）已知过抛物线y
