300米,卡尔每分钟跑200米。
两人从起跑线同方向出发,经过多长时间米德第一次追上卡尔?讲解重点:理解环形追及问题第一次追上,路程差就是一圈的长度。
师:仔细读题,你得到了什么信息?生:他们是围绕着一条长400米的环形跑道练习长跑。
米德每分钟跑300米,卡尔每分钟跑200米。
两人从起跑线同方向出发。
师:条件中我们看到米德跑的比卡尔快,怎么才能够追上卡尔呢?生:只要米德比卡尔多跑了1圈才可以追上。
师:没错,很聪明,这样的问题我们把它们叫做环形跑道的追及问题。
米德比卡尔多跑了1圈,就是多跑多少米?生:1圈就是400米,说明米德比卡尔多跑400米。
师:我们知道是一个追及问题,问题是经过多长时间米德第一次追上卡尔?要求的是追及问题的什么?生:追及时间。
师:要求追及时间就必须知道什么?生:路程差和速度差。
师:米德比卡尔多跑400米。
就是追及问题中的什么?生:路程差。
师:知道了路程差,速度差怎么求呢?生:根据两人跑步的速度,可知速度差为:300-200=100(米/分钟)。
师:追及时间怎么求?生:由追及时间=路程差÷速度差,求得追及时间为400÷(300-200)=4(分钟)。
板书:400÷(300-200)=4(分钟)答:经过4分钟米德第一次追上卡尔。
练习3:(5分)在200米的环形跑道上,欧拉在阿派后面40米处,两人同时同方向出发,欧拉的速度是6米/秒,阿派的速度为8米/秒,问多少秒后阿派第一次追上欧拉?分析:从条件中可以看出阿派的速度比欧拉快,而要我们求经过多长时间阿派第一次追上欧拉,因为欧拉在阿派后面40米同时同方向出发,说明阿派比欧拉多跑了(200-40)米才可以追上,即:(200-40)米就是路程差,再根据两人跑步的速度,可知速度差为:8-6=2(米/秒),再由追及时间=路程差÷速度差,求得追及时间。
板书:(200-40)÷(8-6)=80(秒)答:80秒后阿派第一次追上欧拉。

第3讲:巧妙求和(教案)课前知识复习1.某超市有5筐大米,如果从每个筐中取出60千克,那么5个筐里剩下的大米正好是原来的3筐。
原来每个筐里装多少千克大米?60*5/(5-3)=1502.有6筐梨,每筐梨的个数相等,如果从每筐中取出30个,那么6筐梨剩下的个数总和比原来2筐梨多24个,原来每筐有梨多少个?(30*6+24)/(6-2)=51引入若干个数排成一列称为数列。
数列中的每一个数称为一项。
其中第一项称为首项,最后一项称为末项,数列中项的个数称为项数。
从第二项开始,后项与其相邻的前项之差都相等的数列称为等差数列,后项与前项的差称为公差。
在这一章要用到两个非常重要的公式:“通项公式”和“项数公式”。
通项公式:第n项=首项+(项数-1)×公差项数公式:项数=(末项-首项)÷公差+1一:精讲精练【例题1】有一个数列:4,10,16,22.…,52.这个数列共有多少项?【思路导航】容易看出这是一个等差数列,公差为6,首项是4,末项是52.要求项数,可直接带入项数公式进行计算。
项数=(52-4)÷6+1=9,即这个数列共有9项。
练习1:1.等差数列中,首项=1.末项=39,公差=2.这个等差数列共有多少项?答案:39-1=38 38 /2=19 19+1=202.有一个等差数列:2.5,8,11.…,101.这个等差数列共有多少项?答案:101-2=99 99/3=33 33+1=34【例题2】有一等差数列:3.7,11.15,……,这个等差数列的第100项是多少?【思路导航】这个等差数列的首项是3.公差是4,项数是100。
要求第100项,可根据“末项=首项+公差×(项数-1)”进行计算。
第100项=3+4×(100-1)=399.练习2:1.一等差数列,首项=3.公差=2.项数=10,它的末项是多少?答案:10-1=9 9*2=18 3+18=212.求1.4,7,10……这个等差数列的第30项。

He adds, “Today I can sit in my drawing room and talk big, but the millions who go to the movies will reject what I am saying unless I keep them in mind.” In other words, there are inherent (内在的) limitations in making good and realistic cinema in Indian. This view is, however, challenged by some.According to Ravi Gupta, Managing Director of the National Film Development Corporation which prides itself on making good quality films, “It is a media-created myth that parallel(to Hollywood masala films) cinema is dead.In fact,art films are more viable(能生存的) than commercial films.”Be that as it may, one thing is for certain.Hindi films have probably done more for India’s national integration (一体化) than any other medium. Hindi films and film songs are watched and hummed all over the country, not with st anding the country’s linguistic plurality (多数). Hindi, which is India’s national language but is not spoken and understood in all parts of India, has made its impact through the medium.Another positive aspect is that Indian cinema is the most all embracing,nonreligious part of India’s fractured social landscape. For instance, out of the six top actors listed by the newspaper,the Times of India,three are Muslims:Shah Rukh Knhan, Aamir Khan and Salman Kan. Therefore, despite all its acts of omission and commission, Indian cinema, in some ways, is a progressive phenomenon.核心词汇1.critic n.批评家,评论家【巧记】critical a.批评的,批判的‖criticize v.批评,批判‖criticism n.批评,批判【搭配】be critical to 对……挑剔‖be critical of 苛求2.prominent a.凸起的,显著的,杰出的【巧记】prominently ad.突出地3.dramatize vt.改编成剧本【巧记】drama n.剧本,戏剧‖dramatic a.戏剧性的,巨大的4.reject vt.拒绝接受,抵制【巧记】rejection n.拒绝,抵制,驳回5.limitation n.限制,局限性6.parallel a.平行的,相似的n.平行线vt.与……平行【搭配】in a parallel with 和……平行mercial a.商业的,商务的n.商业广告8.linguistic a.语言的【巧记】linguistically ad.语言上9.fracture n.骨折,破裂,裂缝10.omission n.省略,删除11.reflect v. 反映,显示,反射,深思,反省【巧记】reflection n. 倒影,反映,表达,非议,批评,深思,考虑12.realistic a. 现实的,实际可行的,现实主义的,逼真的13.medium a. 中等的【巧记】medium a. 中等的,适中的‖medium n. 媒介物,传导体,新闻媒介,传播媒介,手段,工具【搭配】by/through the medium of 以……为媒介,通过核心词组be rooted in 根植于……in addition 另外keep…in mind 记住Passage 2Long after the 1998 Would Cup was won, disappointed fans were still cursing the disputed refereeing (裁判) decision than denied victory to their team. A researcher was appointed to study the performance of some top referees.The researcher organized an experimental tournament (锦标赛) involving four youth teams. Each match lasted an hour,divided into three periods of 20 minutes during which different referees were in charge.Observers noted down the referees errors,of which there were 61 over the tournament. Converted to a standard match of 90 minutes,each referee made almost 23 mistakes, a remarkably high number.The researcher then studied the videotapes to analyse the matches in detail. Surprisingly, he found that errors were likely when the referees were close to the incident. When the officials got it right, they were, on average, 17 meters away from the action. The average distance in the case of errors was 12 meters. The research shows the optimum (最佳的) distance is about 20 meters.There also seemed to be an optimum speed. Correct decisions came when the referees were moving at a speed of about 2 meters per second. The average speed for errors was 4 meters per second.If FIFA,football’s international ruling body, wants to improve the standard of refereeing at the next Would Cup, it should encourage referees to keep their eyes on the action from a distance, rather than rushing to keep up with the ball, the researcher argues.He also says that FIFA’s insistence that referees should retire at age 45 may be misguided. If keeping up with the action is not so important, their physical condition is less critical.核心词汇1.curse v.咒骂,诅咒n.咒骂,咒语;祸害2.dispute vt.争论3.deny v.否认,拒绝【巧记】denial n.否定,拒绝承认,克制【搭配】deny doing 否认做……‖There is no denying ……不容否认4.appoint vt.任命,委派,约定,指定【巧记】appointive a.委任的‖appointer n.指定人‖appointment n.约会,约定,任命,委派5.performance n.履行,完成,演出,表演【巧记】perform v.履行,完成,表演‖performer n.演奏者6.involve vt.使卷入,使参与,牵涉,包含【巧记】involvement n.卷入,牵连【搭配】involve in 与……相关,牵涉到……7.period n.一段时间,时间,课时,期间【巧记】periodic a.同期的,定时的‖periodical n.期刊,杂志‖periodically ad.周期地,定期地8.charge vt.装满,收费,使充满,指控,充电n.收费,罪名,负费,电荷【巧记】charger n.委托人【搭配】be charged with 负……责任,弃满着,被指控‖charge for 收……费‖in charge of ……负责,主管‖take charge 开始管理,接管‖in the charge of 受……的管理9.error n.错误,误差10.convert vt.使转变,更改【巧记】convertible a.可转换的,可转变的,可改变的‖converter n.转换器11.analyse vt.分析,分解【巧记】analyzable a.可以分析的‖analysability n.分析,能力‖analysation 分解,分析‖analyser n.分析者‖analyst n.分析者12.incident n.事件,事变【巧记】incidence n.发生率‖incidental a.附带的,偶然的‖incidentally ad.附带地,顺便提及13.argue vi.争论,争辩vt.主张,争论,劝说14.insistence n.坚持15.critical a.批评的,批判的,挑剔地核心词组in charge 负责任be converted to sth. 转换,换算为……on average 平均地keep one’s eyes on 注视rather than 而不是keep up with 跟上Passage 3Sport is not only physically challenging but it can also be mentally challenging.Criticism from coaches, parents, and other teammates, as well as pressure to win can create an excessive amount of anxiety or stress for young athletes(运动) Stress can be physical,emotional or psychological and research has indicated that it can lead to burnout. Burnout has been described as dropping or quitting of an activity that was at one time enjoyable.The early years of development are critical years for learning about oneself. The sport setting is one where valuable experiences can take place. Young athletes can, for example, learn how to cooperated with others, make friends, and gain other social skills that will be used throughout their lives.Coaches and parents should be aware,at all times,that their feedback to youngsters can greatly affect their children. Youngsters may take their parents and coaches criticisms to heart and fine a flaw (缺陷) in themselves.Coaches and parents should also be cautious that youth sport participation does not become work for children. The outcome of the game should not be more important than the process of learning the spot and other life lessons.In today’s youth sport setting,young athletes may be worrying more about who will win instead of enjoying themselves and the sport.Following a game many parents and coaches focus on the outcome and find fault with youngsters’ performances.Positive reinforcement should be provided regardless of the outcome.Research indicates that positive reinforcement motivates and has a greater effect on learning than criticism. Again, criticism can create high levels of stress, which can lead to burnout.核心词汇1.physically a.自然地,物质地,内体上地【巧记】physical a.身体的,物质的【搭配】physical labor 体力劳动‖physical condition 身体状况2.challenge n.挑战,艰巨的任务vt.反对,向……挑战,对……怀疑【巧记】challenging a.具有挑战性的‖challenger n.挑战者3.mentally ad.精神上地,脑力地【搭配】mental labor 脑力,劳动4.criticism n.批评,评论【巧记】critic n. 批评家‖critical a.批判的‖critically ad.批评地,危急地【搭配】be critical to…对……很挑剔‖be critical of 苛求的,挑剔的‖make criticisms on 对……批评5.pressure n.压力,压强,强制,压迫【巧记】press vt.压,按,紧握n.新闻界,出版介‖pressing a.紧迫的,迫切的6.stress n.压力,紧张7.emotional a.感情上的【巧记】emotionally ad.感情地‖emotion n.情感,激动,激情【搭配】with emotion 动情地8.psychological a.心理(上)的,心理学的【巧记】psychologically ad.心理上地,心理学地‖psychology n.心理学,心理‖psychologist n.心理学家9.indicate vt.表示,显示10.describe vt.叙述,描述,形容【巧记】description n.描写,记叙文,说明文‖descriptive a.描述的,说明的【搭配】describe…as…把……描绘成……11.aware a.意识到的,觉察到的【巧记】awareness n.意识,觉悟‖unaware a.不知道的‖unawareness n.无意识【搭配】be aware of 明白,意识到某事【辨析】aware, consciousaware 指通过自己的感官活动来感知;conscious 指大脑已接受了感官的信号,一般表示对事实、真实情况等的清醒地内在了解。
