浙江省温州中学2022-2023学年高一上学期10月月考英语试卷(含答案)

浙江省温州中学2022-2023学年高一上学期10月月考英语试卷学校:___________姓名:___________班级:___________考号:___________ 一、阅读理解Almost every child is scared of something, from monsters in the cupboard to dogs in the park. But the fact that such fears are common and normal doesn’t mean they can be taken lightly. Kids experience fears and phobias(恐惧症) much more strongly than adults. And the influence of the fear can be physical as well as psychological(心理的). It can build up so they almost seem scared of everything-a kind of childhood anxiety. Dr. Creswell says: “Your child may always seem to expect the worst to happen and lack confidence in his or her ability to deal with any challenge.” So don’t make the same old mistake of treating them as if they’re silly for being a “scaredy cat”. Handling the fears is essential.Children can be born nervous and, if you have such a baby, you’ll ten d to prevent them from getting worried. So if they fear dogs, you’ll keep them away from dogs, but in fact that can just confirm to the child that dogs are scary. What is worse, keeping your child away from what they fear can turn that feeling into a phobia. Instead, you should encourage them to get in touch with the thing they fear, in a safe and supportive environment. Dr. Andy Field, a researcher of childhood fears, says: “You shouldn’t force, for example, a dog anxious child to go up to a dog. But you can approach it yourself, show them there is nothing to be afraid of, stroke(抚摸) it, and talk about the dog being friendly. Once your child dares to stroke a dog-one that’s good with children, of course-then you should encourage them to carry on until they feel calmer, and reward them for ‘being brave’.”1.Children’s fears are usually taken lightly because __________.A. they will not develop into phobiasB. their influence is psychologicalC. they exist widely in the worldD. they will disappear gradually2.If we fail to help children to overcome fears, they will ___________.A. make the same old mistakeB. overcome them by themselvesC. experience the worst of thingsD. grow up lacking self confidence3.According to Dr. Andy Field if a child is afraid of a cat, parents should __________.A. tell the child not to be afraid of itB. show the child how to approach itC. keep the child away from itD. ask the child to stroke itYou get anxious if there’s no wi-fi in the hotel or mobile phone signal up the mountain. You feel upset if your phone is getting low on power and you secretly worry things will go wrong at work if you’re not there. All these can be called “always on” stress caused by smart phone addiction.For some people, smart phones have liberated them from the nine-to-five work. Flexible working has given them more autonomy (自主权) in their working lives and enabled them to spend more time with their friends and families. For many others though, smartphones have become tyrants in their pockets, never allowing them to turn them off, relax and recharge their batteries.Pittsburgh-based developer Kevin Holesh was worried about how much be was ignoring his family and friends in favor of his iPhone. So he developed an app——Moment-——to monitor his usage. The app enables users to see how much time they’re spending on the device and set up warnings if the usage limits are broken. “Moment’s goal is to promote balance in your life,” his website explains. “Some time on your phone, some time off it enjoying your loving family and friends around you.”Dr. Christine Grant, an occupational psychologist at Coventry University, said, “The effects of this ‘always on’ culture are that your mind is never resting, and you’re not giving your body time to recover, so you’re always stressed. And the more tired and stressed we get, the more mistakes we make. Physical and mental health can suffer.”And as the number of connected smart phones is increasing, so is the amount of data. This is leading to a sort of decision paralysis (瘫痪) and is creating more stress in the workplace because people have to receive a broader range of data and communications which are often difficult to manage. “It actually makes it more difficult to make decisions and many do less because they’re controlled by it all and feel they can never escape the office,” said Dr. Christine Grant.4.What’s the first paragraph mainly about?A. The popularity of smart phones.B. The progress of modem technology.C. The signs of “always on” stress.D. The cause of smartphone addiction.5.Kevin Holesh developed Moment to ________.A. research how people use their mobile phonesB. help people control their use of mobile phonesC. make people spend more time with their familyD. increase the fun of using mobile phones6.What’s Dr. Christine Grant’s attitude towards “always on” culture?A. Confused.B. Positive.C. Doubtful.D. Critical.7.According to the last paragraph, a greater amount of data means ________.A. we will become less productiveB. we can make a decision more quicklyC. we will be equipped with more knowledgeD. we can work more effectivelyResearch carried out last year stressed the growing challenge facing employers in terms of managing and supporting the UK’s aging workforce.Figures from the Office for National Statistics have suggested that the number of people aged 65 and over still working has reached 1.19 million—up 25,000 from a year ago. There were also now more people aged 50-74 in work than ever before. However, the overall trend was hiding the fact that 12% people are forced to stop working before reaching state pension age because of ill health or disability.Nearly half a million (436,000) workers who are within five years of state pension age have had to leave work for medical reasons, with an apparent divide between the North (worse) and South (better). Those in the lowest-paid jobs, including cleaners, leisure industry workers and people doing heavy laboring jobs, were twice as likely to stop working before retirement age, because of sickness and disability than managers or professionals.Within this, the needs of the “sandwich generation”— those juggling work with caring for elderly dependents as well as children — needed to be given greater priority (优先权) by employers, a white paper by insurer and health care provider concluded.Its research argued that 66% of managers think the average age of retirement in their organization will increase in the next 5 to 10 years. Yet, 36% reported being unaware of anything their organization did to attract, keep and engage older staff. Fewer than a quarter (23%) of employees said they felt supported by their employer with their responsibilities for caring for a loved one.This was perhaps unsurprising, given that only 28% of managers said their organization had formal policies and practices in place to support these employees, argues health caredistribution director Chris Horlick.8.According to the passage, who is more likely to leave work before retirement age?A. Tom, a physician.B. Jason, a language teacher.C. Henry, a construction worker.D. Bill, a bank manager.9.The present support from the employers can be best described as _________.A. movingB. dissatisfyingC. inspiringD. surprising10.What is the main idea of the passage?A. Old employees are well attended in the UK.B. Aging workforce should be well supported in the UK.C. Employers show responsibilities for supporting their employees.D. UK employers are facing challenges in supporting aging workforce.二、七选五11.If you are hungry, what do you do? Have your favorite meal and stay quiet after that?①_______ But it never lets you know, because, you keep it busy thinking about your friends or favorite stars. So it silently serves your needs and never lets itself grow. When mind loses its freedom to grow, creativity sets a full stop. This might be the reason why we all sometimes think “What happens next?”, “Why can’t I think?”②_______ Why reading but not watching TV? It is because reading has been the most educative tool used by us right from childhood. Since it develops other aspects of our life, we have to take help from reading.Once your read a book, you run your eyes through the lines and your mind tries to explain something to you. ③_______ Now this seed is unknowingly used by you to develop new ideas. If it is used many times, the same seed can give you great help to relate a lot of things, which you would have never thought of in your wildest dreams!This is nothing but creativity ④_______ Within no time you can start talking with your friends in English or any other language and never run out of the right words.So guys, do give food for your thoughts by reading, reading and more reading. ⑤_______ Go and get a book!A. Also this makes a significant contribution to your vocabulary.B. Reading can help you make more friends too.C. The interesting part of the book is stored in your mind as a seed.D. Why not do some reading while you are hungry.E. Now what you waiting for.F. Hunger of the mind can be actually solved through wide reading.G. Just like your stomach, your mind is also hungry.三、完形填空(20空)If you have ever driven in the mountains on a cool autumn morning, then you knowsmiled and drove, singing a song in my heart. I thanked God for both the sunshine and theour life.forever struggle to live in God’s light.12.A. photo B. sea C. picture D. drop13.A. turned on B. put on C. turned off D. put off14.A. challenge B. disappointment C. devotion D. pain15.A.

附:教学设计及反思
课题:必修1§1.3.1单调性与最大(小)值(第一课时)
温州中学赵曙
1.教材分析
本节课是新课程人教A版高中数学(必修1)§1.3.1单调性与最大(小)值的第一课时.单调性是函数的一个重要性质,在中学数学内容里有十分重要的地位.它和后面的函数奇偶性,合称为函数的基本性质,是今后研究指数函数、对数函数、幂函数及其他函数单调性的理论基础;另外在比较几个数大小、对函数作定性分析以及与不等式等其他知识的综合应用上都有广泛的应用;同时在这节中利用函数图象来研究函数性质的数形结合思想将贯穿于我们整个高中数学教学.教科书让学生观察已学函数的图象,通过探究、分析、归纳、总结,给出了函数单调性的概念,明确了函数单调性是相对于某个区间而言的,然后由单调性的定义对函数单调性进行较为严格的证明;例题的设计由浅入深,由直观到抽象。

2.学情分析
2.1学生在初中已粗略研究过一些函数的增减性,对单调性已有一定的感性认识,这对概念的理解有一定的好处。

2.2由于学生只学过一次函数、正反比例函数、二次函数,所以对单调性的研究也只能限于这几种函数。

从学生的认知结构来看,他们只能根据图象观察出变化趋势,所以在教学中要充分利用好图象的直观性,发挥多媒体教学的优势。

2.3由于学生在概念的掌握上缺少系统性、严谨性,因此要在概念的形成上下工夫。

在课堂上突出对概念的分析不仅仅是为了分析单调性的定义,而且想让学生对如何学会、弄懂一个概念有初步认识,并且在以后的学习中学有所用。

3.教学目标
(1)知识与能力目标:
①理解增(减)函数的概念。

②通过观察一些函数图象的特征,形成增(减)函数的直观
认识. 再通过具体函数值的大小比较,认识函数值随自变量的增大(减小)的规律,由此得出增(减)函数单调性的定义。

③掌握用定义证明函数单调性的步骤,培养用代数推理证明方法解决函数单调性问题的能力。

④函数单调性的研究经历了从直观到抽象,以图识数的过程,在这个过程中,让学生通过自主探究活动,体验数学概念的形成过程的真谛,培养学生分析、归纳、总结、及数学表达等基本数学思维能力。

(2)过程与方法目标:
①通过已学过的函数特别是二次函数,理解函数的单调性及其几何意义。

②学会运用函数图象理解和研究函数的性质。

③能够熟练应用定义判断与证明函数在某区间上的单调性.(3)情感态度与价值观目标:
使学生感到学习函数单调性的必要性与重要性,增强学习函数的紧迫
感;培养学生积极进行数学交流,乐于探索创新的科学精神以及严谨的治学态度。

4.教学重难点和关键点
教学重点:形成增(减)函数的概念,利用函数的单调性定义证明函数的单调性。

教学难点:利用函数的单调性定义证明函数的单调性。

教学关键点:用数学语言刻画函数值随自变量的变化而变化。

5.教学方法
探究式教学法
6.学法与教学用具
6.1从观察具体函数图象引入,直观认识增减函数,利用定义证明函数单调性。

通过练习、交流反馈,巩固从而完成本节课的教学目标。

6.2教学用具:投影仪、计算机.
7.教学流程






8.教学过程设计
9.教学反思
(1)本教学设计采用现代教学模式,即:创设情境,引导探究,质疑答辩,实例练习,归纳小结的教学模式,在教学过程中,能为营造一个宽松、和谐、积极、民主的学习氛围,使每位学生在“观察问题、分析问题、解决问题”中成为问题的探索者,研究者和发现者。

(2)要实现新知的建构学习,教师创设适当的情境十分的重要.这可以很好的激发学生的兴趣,激发他们的求知欲,有助于探索新知.。
