2023-2024学年江苏省常州市联盟学校高一下学期期末学情调研英语试题Scientists play a crucial role in advancing technology and improving our quality of life. Consider thework of Marie Curie, who discovered radium and polonium, opening up new frontiers in the field ofradioactivity and laying the foundation for modern nuclear medicine. Her research has led to the development of life-saving treatments and diagnostic(诊断的)tools that have benefited countless patients.Another remarkable scientist is Albert Einstein. His theory of relativity changed our understanding of the universe, challenging conventional wisdom and inspiring countless subsequent studies in physics. This has not only deepened our knowledge of the cosmos but also led to technological advancements such as GPS navigation, which relies on the principles of relativity for correct positioning.Isaac Newton’s laws of motion and universal gravitation provided a framework for understanding the physical world and paved the way for modern engineering and aerospace technology. The applications of his theories are obvious in everything from the construction of buildings to the launch of satellites.Charles Darwin’s theory of evolution by natural selection transformed our understanding of the diversity of life on Earth. It has had far-reaching implications in fields such as genetics, ecology, and conservation biology, guiding our efforts to protect and preserve the natural world.Nikola Tesla’s contributions to electri cal engineering, particularly in the development of alternating current(交流电), have powered our modern world. Without his innovations, our reliance on electricity for lighting, communication, and countless other applications would be severely limited.1. Who discovered radium and polonium?A.Albert Einstein. B.Isaac Newton.C.Marie Curie. D.Charles Darwin.2. Which of the following is a major and biggest difference between Albert Einstein and Isaac Newton?B.Their nationality.A.The field of science they mainlycontributed to.D.Their educational background.C.The century in which they did theirresearch.3. Which of the following is a common feature shared by all the scientists mentioned?A.They all made their discoveries in the 20th century.B.They were all from the same country.C.They all faced significant opposition to their work during their lifetimes.D.They all had a deep and lasting impact on the advancement of science and humanknowledge.My childhood memory is closely connected with hunger. Unable to provide enough food to feed its ever-increasing population, the People’s Republic had to adopt a food ration(定量)system to ensure equal supply of food for three decades—the ration for an adult in an urban area was 15 kilograms of wheat, rice, com or sorghum per month.Many young people today might not understand why I’m talking about hunger when an adult’s monthly quota for food grains was 15kg, especially because half of that would perhaps be enough for them for a month. But that’s all an adult c ould consume up to the 1970s, because cooking oil, meat, eggs and sugar were strictly controlled.Although the ration system ensured everybody had a share of the available food and prevented starvation deaths, it led to malnutrition(营养不良)among people of every age.On launching reform and opening-up. China realized a major reason for food shortage was farmers not getting their rightful due under the system then. So the government distributed the collectively-owned farmlands to households and farmers. Within years, the farm yield almost doubled, helping China to abandon the food rationing system in 1993.Now, enough food supply and much money have changed Chinese people’s dietary habits. Many youths refuse to learn cooking, arguing that they can source their meals from restaurants or take-out outlets. As a result, one can see thousands of electric bike riders zigzagging the streets to deliver breakfast, lunch or dinner.Paradoxically, Chinn is now battling over-nutrition. One would be lucky to not find a few overweight boys and girls in a class. When I meet with my former classmates, many of whom are overweight or suffering from over-nutrition-related illnesses, we sometimes talk about the “good old food ration days” when almost no one needed to worry about con trolling weight.4. What is the main purpose of China’s adopting a food ration system?A.To feed enough food to people. B.To ensure less waste of food.C.To avoid increase of population. D.To fight against food shortage.5. What can we infer from paragraph 2?A.Lacking other nutrition made 15kg food grains not enough for an adult.B.Young people today consume less food grains to avoid overweight problem.C.People in poverty had no access to oil, meat, eggs and sugar in the 1970s.D.The farm yield almost doubled with the development of faring technology.6. What does the underlined word “Paradoxically” in Paragraph 5 most probably mean?A.Consequently. B.Unexpectedly.C.Similarly. D.Reasonably.7. Why does the author write the article?A.To suggest our country adopting food ration again.B.To advise people to have enough food.C.To record the change in the development of society.D.To introduce a healthy lifestyle to young people.Playing music requires fine motor skills, which are controlled in both hemispheres(大脑半球)of the brain. It also combines language and mathematics, which the left hemisphere is more involved in, with the novel and creative content that the right does well in. For these reasons, playing music has been found to increase the volume and activity in the brain’s corpus callosum(肼胝体), the bridge between the two hemispheres, allowing messages to get across the brain faster and through more different ways. This may allow musicians to solve problems more effectively and creatively, in both academic and social settings.Because making music also involves creating and understanding its emotional content and message, musicians often have higher levels of decision-making function, a category of interlinked tasks that includes planning, strategizing, and attention to detail and requires immediate analysis of both cognitive(认知的)and emotional aspects. This ability also has an impact on how our memory systems work. And, indeed, musicians exhibit better memory functions, creating, storing, and retrieving memories more quickly and efficiently. Studies have found that musicians appear to use their highly connected brains to give each memory multiple tags(标签), such as a conceptual tag, an emotional tag, an audio tag, and a contextual tag, like a good Internet search engine.How do we know that all these benefits are unique to music, as opposed to, say, sports or painting? Or could it be that people who go into music were already smarter to begin with? Neuroscientists have explored these issues, but so far, they have found that the artistic and aesthetic aspects of learning to play a musical instrument are different from any other activity studied, including other arts. And several randomized(随机的)studies of participants, who showed the same levels of cognitive function and neural processing at the start, found mat those who were exposed to a period of music learning showed improvement in multiple brain areas, compared to the others.8. Which of the following could be the best title for the passage?A.The Connection Between Music and Brain Activity.B.The Secret of Musicians’ Success.C.How Music Changes Our Lives.D.The Impact of Music on Motor Skills.9. What does playing music increase in the brain?A.The size of the left hemisphere.B.The size of the right hemisphere.C.The volume and activity in the brain’s corpus callosum.D.The number of neural connections in the front part of brain.10. What have neuroscientists found about-the benefits of playing music?A.They are not unique. B.They are the same as those of sports.C.They are the same as those of painting. D.They are different from any other activitystudied.11. What did the randomized studies find about those exposed to music learning?A.They had worse cognitive function.B.They showed no improvement in brain areas.C.They showed improvement in duty brain area.D.They showed improvement in multiple brain areas.Last week a study was published showing that people with bowel cancer(肠癌)who drink coffee—quite a lot of coffee, two to four cups a day—were less likely to suffer a return of the disease. Experts have said that if the results hold in further studies, coffee could be prescribed(开处方)to cancer patients on the NHS(National Health Service). That coffee does have an effect on human function is no doubt—but whether that impact is beneficial or harmful has been controversial(有争议的)since its beginning in the mid-15th century.The native peoples of the forests of Kaffa in south-west Ethiopia searched for berries(浆果)from wild coffee plants that were shipped across the Red Sea to prepare the decoction(煮出的汁)known as qahwa, which was used to reduce their desire for sleep. Once mainstream Islamic courts said coffee was not poisonous, consumption became widespread among the Muslim populations in the Middle East and the Ottoman empire.First regarded as a form of medicine, Turkish traders introduced coffee to Venice, where it was prescribed for digestive disorders. It was served in small, cold potions. London’s first coffee houses appeared in the 1650s, attracting customers with the advertised health benefits of the new beverage. However, not all were convinced. The 1674 Women’s Petition Against Coffee declared that too much coffee consumption weakened men and made them unproductive.Since the 1960s, mass surveys of coffee drinkers have shown different results of its impact. In 1991 the World Health Organization listed coffee as a possible cause of cancer, but in 2016 this conclusion was reversed(反转)as more studies have shown a larger number of positive outcomes being associated with coffee drinking. Following centuries on the defensive(处于守势), it may be time for coffee professionals to dust down those handbills and channel their inner Pasqua Rosée.12. What was the main finding of the recent study mentioned in paragraph 1?A.Coffee has no impact on human function.B.Drinking coffee reduces the risk of bowel cancer.C.People with bowel cancer should avoid drinking coffee.D.Coffee has no effect on the return of bowel cancer.13. Why does the writer mention the history of coffee consumption?A.To highlight the cultural significance of coffee in different regions.B.To emphasize the historical controversy around coffee’s health effects.C.To show coffee’s long-standing popularity and usage.D.To show the link between coffee’s origins and its medical applications.14. Which is the most suitable title for this passage?A.The Dark Side of Coffee: A Hidden Cancer RiskB.The Bitter Drink: Coffee’s Secret in Being PopularC.Uncovering the Truth: Coffee’s Cancer-Fighting HistoryD.Surprising History of Coffee: From Controversial Drink to Potential Cancer Cure15. Which section of the journal might this article belong to?A.Health & fitness. B.Home & garden.C.History & Culture. D.Finance & investment.Around 1830, the Romantic period slowly arose from the delicate form of the Classical period, expanding orchestral(管弦乐的)forces to express emotions and extra-musical ideas they had never expressed before. How was this possible? 16Romantic Period SoundIf you expect the music to have a regular, eight bar phrase(乐节), think again. It might have irregular phrases to throw you off course, like in Schubert’s ‘Unfinished’ Symphony No. 8. 17 It may well be that composers like Mahler jump to an unexpected musical ending, like in his Symphony No. 2. If in doubt, be prepared to forget anything and everything you previously thought about music, and expect to be surprised, attracted, and amazed by the unexpected twists and turns of the Romantic period.Romantic InstrumentsAs music grew more expressive, the standard orchestral instruments just weren’t rich enough for many Romantic composers. So, more were added, including the contrabassoon, bass clarinet and piccolo, xylophones, drums, celestes, harps, bells, and triangles. 18 Listen to how Tchaikovsky makes use of various instruments in the ‘Dance of the Sugar Plum Fairy’ in his ballet, The Nutcracker.Romantic PiecesDespite often being marked as a Classical period composer, Beethoven’s style really covered the two periods. His later works are pretty expansive, conjuring(变戏法般的)life, death, joy, peace, and even the concept of a universal brotherhood in the symphony of all symphonies, his choral Symphony No. 9, written in 1824. 19 It was a one-movement work evoking a story or poem, like Debussy’s dreamy Prélude à l’après-midi d’un faune or Dukas’ Sorcerer’s Apprentice.20 They also expanded the orchestra to express the full range of human emotion through music. But, understandably, this over-indulgent expression had its critics(批判者)who favoured absolute music-music for music’s sake, without a programme or story-and these critics led music into the ever-diverse 20th Century period.After being poorly bred(饲养)by a backyard breeder. Stevie was ________ at a rescue. She was born ________, so her breeder had no ________ to sell her. As soon as Stevie’s parents became aware of her situation, they immediately offered to ________ her. Her eyes were infected(感染)badly and she had congenital glaucoma(先天性背光眼).

1.4实验:用打点计时器测速度[目标定位] 1.了解两种计时器的结构和工作原理,并学会安装和使用.2.掌握测瞬时速度的方法,会用打出的纸带求瞬时速度.3.会用图象表示速度随时间变化的规律.一、了解打点计时器1.作用及分类打点计时器是一种使用交流电源的计时仪器,当电源频率为50 Hz时,它每隔0.02_s打一次点,打点计时器和纸带配合,可以记录物体运动的时间及在一段时间内的位移,供高中学生实验用的计时器有电磁打点计时器和电火花计时器两种.2.电磁打点计时器(1)工作电压:6_V以下的交流电源;(2)原理:接通交流电源后,在线圈和永久磁铁的作用下,振片便振动起来,带动其上的振针上下振动.这时,如果纸带运动,振针就通过复写纸在纸带上留下一行小点.3.电火花计时器(1)工作电压:220_V交流电源;(2)原理:当接通电源、按下脉冲输出开关时,计时器发出的静脉电流经放电针、墨粉纸盘到纸盘轴,产生火花放电,于是在运动的纸带上打出一行点迹.4.两种计时器误差比较电火花计时器使用中运动阻力极小,因而系统误差较小.想一想:计时器打点时,计时器和纸带之间的摩擦会对物体的运动造成影响,用哪种打点计时器做实验时,实验误差更小呢?答案因为电火花打点计时器是靠电火花和墨粉来打点的,所以对纸带的运动带来的阻力很小,使系统误差更小.二、用打点计时器测量平均速度根据v=ΔxΔt可求出任意两点间的平均速度,其中Δx是纸带上两点间的距离,Δt是这两点间的时间间隔.想一想:如果纸带上的点迹分布不均匀,点迹密集的地方表示运动的速度较大还是较小?答案较小三、用打点计时器测量瞬时速度纸带上某一位置的瞬时速度,可以粗略地由包含这一位置在内的一小段位移Δx内的平均速度表示,即根据v=ΔxΔt,当Δt或Δx较小时,用这个平均速度代表纸带经过该位置的瞬时速度.如图141所示,E点的瞬时速度可用D、F两点间的平均速度代表,即v E=Δx Δt .图141想一想:在上图中,用DF 段和DG 段求出的平均速度,哪一个更接近E 点的瞬时速度?答案 因为当Δt 或Δx 较小时,求得的平均速度更接近某点的瞬时速度,所以DF 段求出的平均速度更接近E 点的瞬时速度.四、用图象表示速度速度时间图象(v t 图象):用来描述速度随时间变化关系的图象,图象上的点反映某一时刻的瞬时速度.想一想:利用图象处理实验数据的好处是什么?答案 用图象法处理数据更直观、更具体、更方便.五、实验器材:电火花打点计时器(或电磁打点计时器)、220 V 交流电源(电磁打点计时器使用学生电源)、刻度尺、纸带、墨粉纸盘(复写纸)、导线、坐标纸一、实验步骤1.了解电火花计时器的结构,然后把它固定在桌子上,纸带穿过限位孔,把纸带放到墨粉纸盘的下面.2.把计时器接到220 V 的交流电源上.3.接通电源,用手水平地拉动纸带,纸带上就打出一行小点,随后立即关闭电源.4.取下纸带,从能看得清的某个点数起,数一数纸带上共有多少个点.如果共有n 个点,则用Δt =0.02×(n -1) s 计算出纸带的运动时间Δt .5.用刻度尺测量一下打下这些点纸带通过的距离Δx ,利用v =Δx Δt计算纸带在这段时间内的平均速度.把测量和计算的结果填入表中.二、数据处理1.利用打点计时器测量瞬时速度(1)取一条点迹清晰的纸带便于分析测量.(2)从纸带上能看得清的某个点作为起始点O,以后的点分别标上A、B、C、D、…,如图142所示,测出各点到O点的距离,算出OA、AB、BC、……的距离x1、x2、x3、…….图142打点计时器打点的周期为T.(3)A、B、C、D、……各点的瞬时速度分别为v A=x1+x2 2T、v B=x2+x32T、v C=x3+x42T、v D=x4+x52T、…….把数据填入下表,根据数据判断纸带是否做匀速运动.图1432.图象法表示速度(1)用横轴表示时间t,纵轴表示速度v,建立直角坐标系.根据测量的数据在坐标系中描点,然后用平滑的曲线把这些点连接起来,即得到如图143所示的v t图象.(2)v t图象的意义v t图象非常直观地反映了速度随时间变化的情况,但它并不是物体运动的轨迹.三、注意事项1.使用电火花打点计时器时,应注意把纸带正确穿好,墨粉纸盘位于纸带上方,使用电磁打点计时器时,应让纸带穿过限位孔,压在复写纸下面.2.使用打点计时器时,应使物体停在靠近打点计时器的位置.3.使用打点计时器打点时,应先接通电源,待打点计时器打点稳定之后,再拉动纸带;打点之后应立即关闭电源.4.对纸带进行测量时,不要分段测量各段的位移,正确的做法是一次测量完毕(可先统一测量出各个测量点到起始测量点O之间的距离).5.区别计时点和计数点:计时点是打点计时器在纸带上打出来的点;计数点是从计时点中选出来的具有代表性的点,一般相邻两个计数点之间还有若干个计时点.计数点一般不是从第一计时点开始的,而是选择点迹清晰、与相邻的计时点间距适中的点开始.6.区别打点周期和计时周期:打点周期:两个相邻的计时点的时间间隔,即交流电源的周期,一般为0.02 s;计数周期:两个相邻的计数点的时间间隔,若相邻两个计数点之间还有(n-1)个计时点,则计数周期为T=0.02n s.例1(2013~2014桂林高一期中)用打点计时器可测纸带运动的时间和位移.下面是没有按操作顺序写的不完整的实验步骤,按照你对实验的理解,在各步骤空白处填上适当的内容,然后按实际操作的合理步骤,将各步骤的字母代号顺序写在空白处.A.在电磁打点计时器的两接线柱上分别接上导线,导线的另一端分别接在低压________(填“交流”或“直流”)电源的两个接线柱上.B.把电磁打点计时器固定在桌子上,让纸带穿过________(填“插孔”或“限位孔”),并压在________(填“白纸”或“复写纸”)下面.C.用刻度尺测量从计时开始点到最后一个点间的距离Δx.D.切断电源,取下纸带,如果共有6清晰的点,则这段纸带记录的时间Δt=________.E.打开电源开关,再用手水平地拉动纸带,纸带上打下一系列小点.F.利用公式v=ΔxΔt计算纸带运动的平均速度.实验步骤的合理顺序是________.解析打点计时器使用交流电;把电磁打点计时器固定在桌子上,让纸带穿过限位孔,并压在复写纸下面;若打6个点,则有(6-1)个时间间隔,故这段纸带记录的时间Δt=0.02×(6-1)s=0.1 s;实验步骤的排列一般要先安装器材然后进行实验的思路进行,故实验步骤的合理顺序是:BAEDCF.答案交流限位孔复写纸0.1 s BAEDCF例2(2013~2014海南文昌高一段考)某同学在“用打点计时器测速度”的实验中,用打点计时器记录了被小车拖动的纸带的运动情况,在纸带上确定出A 、B 、C 、D 、E 、F 、G 共7个计数点.其相邻点间的距离如图144所示,每两个相邻的测量点之间的时间间隔为0.10 s .(本题计算结果均保留3位有效数字)图144(1) 在实验中,使用打点计时器操作步骤应先________再________(选填“释放纸带”或“接通电源”).(2) 每两个计数点间还有________个点没有标出.(3) 试根据纸带上各个计数点间的距离,每隔0.10 s 测一次速度,计算出打下B 、C 、D 三个点时小车的瞬时速度,并将各个速度值填入下表.(4)将B 、C 、D 、E 、F 各个时刻的瞬时速度标在图145直角坐标系中,并画出小车的瞬时速度随时间变化的关系图线.图145解析 (1) 在实验中,使用打点计时器操作步骤应先接通电源,再释放纸带;(2) 每两个计数点间还有n =Δt ΔT-1=0.10.02-1=4个点没有标出.

“重建附近”:年轻人如何从现实中获得力量?——人类学家项飙访谈(节录)康岚:您最早在什么时候提出“附近”这个概念?为什么想到提出这个概念?项飙:我第一次提“附近”应该是在2019年夏天,我跟许知远在“十三邀”节目上的对话。
当时好像是在谈现代人的时空观念,为什么现在人们对快递小哥迟到两分钟会非常不耐烦?我们说到现代生活完全是被时间逻辑统治了,空间逻辑消失了。
原来我们对时间的理解是通过人的行动,比方说我和你的距离是一袋烟的工夫,或者说这个距离是从你家走到荷塘边上的那个工夫,其实时间很大程度上是通过空间来衡量的。
但在工业化之后,抽象时间也就是钟表时间变得非常重要。
当这种抽象时间统治了我们的生活,空间就完全变成了附属性的东西。
对快递小哥迟到两分钟会非常不满,是因为你根本不考虑他是从空间中哪个点到餐馆拿了东西,以及路上的交通是怎样的,进你家小区的门时他要跟保安怎样交涉,这些经历性、空间性的东西,你是不管的,你要的就是那个东西要在你规定的时间内送到你的手里。
这种心态是“时间的暴政”造成的。
在这样的场景下,我提到“附近的消失”。
“附近”这个空间的消失,一方面是因为“时间的暴政”,另一方面是因为我们在日常生活里面建立自己对世界的感知越来越通过一些抽象的概念和原则,而不是通过对自己周边的感知来理解。
比如,你的邻居是干什么的,楼下打扫卫生、门口卖水果的人是从哪里来的,他们家在哪里,如果家不在这里,一年回几次家,他们的焦虑和梦想是什么。
这些人对你的生活很重要,因为我们的日常生活就是由他们来组织的,没有他们,我们的生活不能够正常运行。
但是,我们对这些“附近”经常是视而不见的。
这个“附近”,它是一个空间,它的有趣在于它有很强的社会性,它是你这个社会主体的物质基础,把你托起来。

Then I found that my mother was not the best teacher for me. It wasn’t that she shouted, or told me that I was doing poorly. As you can imagine, my mother’s “helpful instructions (指示)” only made me more nervous.Since I could no longer practice with her, the job was placed in the hands of my father. The idea of learning from Dad was not one that thrilled me. I loved him dearly, but I just did not see Dad as someone I could be comfortably learning from. He almost never talked. We shared a typical (典型的) father-daughter relationship. He’d ask how school was, and I’d say it was fine. Unfortunately, that was the most of our conversations. Spending hours alone with someone who might as well have been a stranger really scared me.As we got into the car that first time, I was not surprised at what happened. Dad and I drove around, saying almost nothing, aside from a few instructions on how to turn. As my lessons went on, however, things began to change. Dad would turn the radio up so I could fully appreciate his favorite Stones music. And he actually began talking. I was soon hearing about past failed dates, “basic body” gym class, and other tales from his past, including some of his first meeting with Mom.Dad’s sudden chattiness (爱讲话) was shocking until I thought about why he was telling me so much in the car. In all the years, I had wondered why my father never spoke that much, but I had never stopped to consider that it was because I had never bothered to listen. Homework,friends, and even TV had all called me away from him, and, consequently (因此), I never thought my quiet father had anything to say.Since I began driving with him, my driving skill has greatly increased. More important, though, is that my knowledge of who my father is has also increased. Just living with him wasn’t enough — it took driving with him for me to get to know someone who was a mystery.59.The author couldn’t practice driving with her mother because ________.A. she couldn’t talk with her motherB. her father wanted to teach herC. her mother made her nervousD. she didn’t trust her mother60.At first, the idea of learning driving from her father made her ________.A. happyB. uneasyC. satisfiedD. disappointed61.What surprised the author when the driving lessons went on?A. Her Dad liked modern music.B. Her Dad was the best teacher.C. Her Dad was a chatty person.D. Her Dad told her his sad stories.62.With her story “Car Talk”, the author indicates that ________.A. fathers love their daughters dearlyB. mothers are less patient than fathersC. family members need real communicationD. it takes time to improve the father-daughter relationshipCIt is quite reasonable to blame (指责) traffic jams, the cost of gas and the great speed of modern life, but manners on the road are becoming horrible. Everybody knows that the nicest men would become fierce tigers behind the wheel. It is all right to have a tiger in a cage, but to have one in the driver’s seat is another matter.Road politeness is not only good manners, but good sense. It takes the most cool-headed drivers great patience to give up the desire (欲望) to beat back (反击) when forced to face rude driving. On the other hand, a little politeness goes a long way towards reducing the possibility of quarrelling and fighting. A friendly nod or a wave, of thanks in answer to an act of politeness helps to create an atmosphere (氛围) of good will and becomes so necessary in modern traffic conditions. But such behaviors of politeness are by no means enough. Many drivers nowadays don’t even seem able to recognize politeness when they see it.However, misplaced politeness can also be dangerous. A typical example is that a driver waves a child crossing the street at a wrong place into the path of oncoming cars that may not be able to stop in time. The same goes for encouraging old ladies to cross the road wherever and whenever they want to.An experienced driver, whose manners are faultless (无错误的), told me it would help if drivers learnt to correctly join in traffic stream (潮流) without causing total jams that give rise to unpleasant feelings. Unfortunately, modern drivers can’t even learn to drive, let alone (更不要说) master the roadmanship (驾车技能). Years ago, experts warned us that the fast increase of the car ownership would demand more give-and-take (互让,妥协) from all road users. It is high time for all of us to take this message to heart.63.What’s the best little of the passage above?A. Road PolitenessB. Traffic JamsC. Good MannersD. Modern Drivers64.Troubles on the road are often caused by ________.A. great speedB. traffic jamsC. terrible road conditionsD. the behaviors of the drivers65.According to the writer, a good driver should ________.A. beat back when forced to face rude drivingB. be able to recognize politeness when he sees itC. join in traffic stream quickly however other people feelD. encourage children to cross the roads whenever they want to66.It is not always right for drivers to ________.A. master roadmanshipB. create atmosphere of good willC. encourage old ladies to cross the roadD. give a friendly nod to show politenessDIt’s 10:30 pm, and 11-year-old Brandon Blanco is sound asleep at home. Suddenly, a loud noise wakes him up. Naturally, Brandon reaches for his cell phone. The message becomes clear: “R U awake?”Brandon’s use of technology doesn’t stop there. He also has a computer, a TV and three video-game consoles (控制台) in his room. With so many choices, it’s no surprise that when he isn’t at school, he spends nearly every waking minute using one or more of these devices.Brandon is hardly alone. According to a recent study by the Kaiser Family Foundation, kids aged 8 to18 are spending more time than ever before using electronic devices (电子设备). How much time? More than seven and a half hours a day on average, the study found.The jump is the result of a huge explosion (爆发) in mobile devices, says Victoria Rideout, the lead author of the study. Today, nearly seven out of ten kids have cell phones. Just five years ago, it was four out of ten.Often, kids multitask, or use more than one device at a time. “If you’ve got a chance to do something on your computer and take a phone call and have the TV on in the background, whynot?” media expert Cheryl Olson says.Most experts agree technology has much to offer kids. But some worry the kids could be missing out on other activities like playing outside or hanging out(闲逛) with friends. “It’s a matter of balance,” says Olson. “You’ve got to work on it.”Multitasking while doing homework is another concern. Some kids listen to music, watch TV or use the phone while doing their homework. “It’s important to make sure that you can stop and concentrate on one thing deeply,” says Rideout.With new and exciting devices hitting stores every year, keeping technology use in check (在控制中) is more important than ever. “Kids should try,” adds Rideout. “but parents might have to step in sometimes.”67.Why do children spend more time in using electronic devices (电子设备)?A. Because more electronic devices are available to them.B. Because electronic devices are more exciting than before.C. Because they have less other activities.D. Because they have less homework to do.68.It is known from the passage that ________.A. Brandon Blanco feels very annoyed about his late-night textB. the teenagers using mobile devices have increased by 40% in the past five yearsC. Cheryl Olson is not surprised about kids’ increasing use of mobile devicesD. most experts think teenagers should not use electronic devices for their studies69.Which of the following is an example of multitasking according to the passage?A. Watching TV while using the computer.B. Talking on the phone while staying with others.C. Playing video games on the Internet.D. Listening to music while relaxing.70.According to the passage, Victoria Rideout would probably agree that ________.A. kids should do homework while surfing the InternetB. kids should do homework in a place without disturbanceC. kids should spend more time on homeworkD. kids should have more homework than before第五部分任务型阅读4 Reasons Why Fad (风靡一时的) Diets are Bad for YouA quick weight loss program sounds like a good idea at the time, but you’ll soon discover that fad diets can be more dangerous to your health than beneficial to it. Here are four reasonswhy fad diets are bad for you, plus tips on how to create a diet plan that helps you lose the extra pounds safely — and keep them off.1. You’ll Wind Up Feeling Dehydrated (脱水的)Most of the weight you drop when you lose weight too quickly tends to be water weight, which can lead to rapid dehydration. Your body burns calories and excess (过量的) weight in stages, and if you force your body to lose weight faster than it naturally wants to, you can cause serious health problems for yourself.Tip: When trying to lose weight, remind yourself that water is your friend. To keep from overeating and to stay properly hydrated (含水的), drink one to two glasses before a meal. Also, if you exercise daily, be sure to increase your water intake in order to counteract (抵消,中和) the water lost from sweating (出汗) while working out.2. You’ll Get Tired QuicklyFad diets involve depriving (剥夺) yourself of calories, however, calories are what translate into the energy your body needs to get through the day. If you eat fast or eat less than what your body requires in order to lose weight too quickly, you’ll find yourself feeling tired for most of the day.Tip: Eat smaller meals throughout the day. This will help to boost (促进) your metabolism (新陈代谢), and can provide you with more energy to help you lose weight in a healthy manner.3. You Can Get Serious Digestive (消化的) ProblemsIn actual fact, losing weight too quickly can lead to severe diarrhea (腹泻), to be followed later by constipation (便秘). As with losing water weight, having diarrhea over an extended period of time can lead to dehydration (脱水) — a condition that can be life-threatening.Tip: Ensure that you have a diet which is rich in fibre (纤维).4. You’ll Suffer from Malnutrition (营养不良)Crash diets and fasting are dangerous because they restrict (限制) you from consuming (消耗) fats and carbs (碳水化合物), but they’re also unsafe since they prevent your body from getting the vitamins and minerals it needs. If you restrict your body from its normal caloric intake over a long period of time, your body will be deprived (使丧失) of important nutrients (营养) and you’ll become malnourished.Tip: A healthy, well-balanced diet is the key to proper weight loss. Talk to your doctor about dietary supplements (补充物) if you are concerned about the amount of nutrients you’re getting.第六部分:单词拼写(根据中文或首字母提示,用模块三词汇表中单词的适当形式填空。
一、单项选择题1.(福建省石光华侨联中2012届高三上学期期末测试理综卷)一个质量为M 、静止的不稳定原子核,当它放射出质量为m 、速度为v 的粒子后,原子核剩余部分的速度为( )A .-vB .m M mv-- C .M m mv-- D .M mv-3.(北京市第三十一中学2012届高三期中考试)如图所示,运动员挥拍将质量为m 的网球击出。
如果网球被拍子击前、后瞬间速度的大小分别为v 1、v 2,v 1与v 2方向相反,且v 2 > v 1。
忽略重力,则此过程中拍子对网球作用力的冲量( )A .大小为m (v 2 – v 1 ),方向与v 1方向相同B .大小为m (v 2 + v 1 ),方向与v 1方向相同C .大小为m (v 2 – v 1 ),方向与v 2方向相D .同大小为m (v 2 + v 1 ),方向与v 2方向相同4.(云南省昆明一中2012届高三第三次月考理综卷)关于物体的动量,下列说法中正确的是 ( )A .物体的动量越大,其惯性也越大B .同一物体的动量越大,其速度一定越大C .物体的加速度不变,其动量一定不变D .运动物体在任一时刻的动量方向一定是该时刻的位移方向4.B 解析:此题考查有关动量大小的决定因素和矢量性.物体的动量越大,即质量与速度的乘积越大,不一定惯性(质量)大,A 项错;对于同一物体,质量一定,所以速度越大,动量越大,B 项对;加速度不变,但速度可以变,如平抛运动的物体,故C 项错;动量的方向始终与速度方向相同,与位移方向不一定相同,D 错误。
6.(山东省曲阜一中2012届高三摸底考试)一炮艇总质量为M,以速度v0匀速行驶,从艇上以相对炮艇的水平速度v沿前进方向射击一质量为m的炮弹,发射炮弹后炮艇的速度为v′,若不计水的阻力,则下列各关系式中正确的是()A.Mv0 =Mv′+mvB.M v0 =(M-m)v′+mvC.M v0 =(M-m)v′+m(v+ v0)D.M v0 =(M-m)v′+m(v+ v′)6.D 解析:发射炮弹的过程,系统动量守恒,发射前,系统的总动量为M v0,发射炮弹后,炮艇的质量变为M-m,速度为v′,炮弹质量为m,对地速度为v+ v′,所以系统总动量为(M-m)v′+m(v+ v′),本题答案为D。
