高三第一轮复周测卷·数学(十八)23G3ZCJ(新高考)数学-R-必考=FJ·A【解题分析】(1)设AC的中点为O,连接BO,PO.由题意知PA=PB=PC=2,PO=1,AO=BO=CO=1,因为在△PAC中,PA=PC,O为AC的中点,所以POAC,因为在△POB中,PO=1,OB=1,PB=√2,所以PO⊥OB,因为AC∩OB=O,AC,OB二面ABC,所以PO⊥面ABC,因为POC面PAC,所以面PAC⊥面ABC.(2)由PO⊥面ABC,OB⊥AC,建立如图所示的空间直角坐标系,则O(0,0,0),C(1,0,0),B(0,1,0),A(一1,0,0),P(0,0,1),由于OB⊥面APC,故面APC的法向量为OB=(0,1,0),设面PBC的法向量为n=(x,y,之),由于n·BC=0BC=(1,-1,0),PC=(1,0,-1),则由n·P-0'0令x=1,得y=1,=1,即n=(1,1,1),c0sm,0B)得
脆弱。每个人的悲剧被安放得自然而然又合情合理,更突出了生命和世界之间无法克服的矛盾。(摘编自王博《〈红楼梦)的悲剧让美好的东西获得根基》)材料三:我认为《红楼梦》是康、雍、乾三朝的社会生活、社会矛盾、历史趋向的一个艺术的总概括和总反映。《红楼梦》里写了两种毁灭,一种是新生事物的毁灭,这就是贾宝玉、林黛玉爱情的毁灭:另一种是古老的荣国府、宁国府的毁灭。前者的毁灭是新的生命由于它还未成熟,经不起狂风恶浪的摧折而毁灭,但它健壮的根系和茁壮的幼茅仍在适宜的土壤里保存着,“野火烧不尽,春风吹又生”,只要有适当的气候,它会继续生长,最终长成大树:而后一种毁灭,是腐朽加腐烂,是生命的尽头,最终是化为粪壤,永远成为过去、不可能再生。所以这两种毁灭,具有两种完全不同的社会意义。前者反映的是历史前进的客观趋势,后者反映的是由荣、宁二府象征的那种腐朽势力的必然死亡。曹雪芹的笔是非常狡狯的,他一再声称此书“亦非伤时骂世之旨,及至君仁臣良父慈子孝,凡伦常所关之处,皆是称功颂德,眷眷无穷,实非别书之可比”。表面上说得非常好听,都是对封建皇帝和朝廷的歌功颂德,但一开头他就写了一桩贪赃枉法的人命案,同时带出了炙手可热的“贾、史、王、薛”四大家族。由此开头,也就开始了他对封建社会的大揭露,大批判。贪赃枉法的贪官贾雨村,是全靠贾府一手提拔起来的,他枉断了薛蟠所犯的人命案以后,还直接向贾府和王子腾报告,这说明一切横行不法的事,都与“四大家族”有关。通过对这个具体的“贾”府的描写,也就可以清楚地看到“这四家皆连络有亲,一损皆损,一荣皆荣,扶持遮饰,俱有照应”的具体情况,而且“各省皆然,倘若不知,一时触犯了这样的人家,不但官爵,只怕连性命还保不成呢!”这就是封建社会政治势力的一张关系网。所以“葫芦僧乱判”一案,实际上是对封建社会、封建官场的一个总揭露和总批判。当然《红楼梦》最最动人之处,是贾宝玉、林黛玉的生死不渝的爱情和他们的爱情悲剧,《红楼梦》是以宝、黛的爱情悲剧来贯通全局的。这个爱情悲剧的内涵是誓死捍卫爱情和婚姻的自主、自择权,主张爱情和婚姻的自由。(摘编自冯其庸《读<红楼梦>》)1.下列对材料相关内容的理解和分析,正确的一项是()(3分)A.《红楼梦》之悲剧不以善恶与灰色三种人的互相攻伐而致成,而是因为性格不同,思想不同,人生见地不同。B.金陵十二钗追求的价值和生活最后都落空,让那些刻意营造的成功或欢乐现得苍白脆弱,体现了小说的悲剧性。C.曹雪芹在《红楼梦》创作中虽假意规避"伤时骂世”,表面上对封建朝廷歌功颂德,但仍有较强的批判意味。D.《红楼梦》的悲剧与希腊悲剧并无不同,都是人生见地的冲突和兴亡盛衰之无常,所体现的悲剧无不是曲线的。2根据材料内容,下列说法正确的一项是()(3分)

Trees don't look at the calendar to see when spring arrives,but they seem to know when spring ishere better than we do.Recently a research takes a look at why trees in cities are turning green earlier thanexpected.The annual shift from winter to spring is a breathtaking event to watch as leaves become greenand a lush(苍翠的)environment reveals itself.While it may be winter,trees in cities are turning green earlier than expected and one of the reasonsis artificial light.City lights brightening the night skies,billboard signs lit up on roadways,and carheadlights all contribute to shifting the regular day to night cycle that plants and trees rely on.In order to stay alive during cruel winters,trees hit the pause button on their growth.Sincetemperatures can vary dramatically throughout the winter the length of daylight is the signal trees look forto safely start growing again and turn green.On average cities are typically 1.8 to 5.4F warmer than rural areas.This is known as the urbanheat island effect.The changes in city environments may affect seasonal changes even more than climatewarming and can affect the allergy (and mosquito season,water cycles,and also affect pollinators(授粉媒介).Scientists use satellite imagery to see when plants turn green.By comparing spring green-ups in the85 largest US cities scientists found that on average trees start to turn green nine days earlier in cities dueto the combined effect of urban heat effect and artificial lights.Despite the worries and concern,it isn't all bad news."With a longer growing season,trees would be able to absorb more carbon dioxide,"A researchersaid."Hopefully they'd have a longer period to do the cooling effect that can help mitigate the urbanheating effect in cities."28.Which might be a factor causing trees to turn green earlier according to the text?A.Timely rain.B.Devoted care.C.Street lamps.D.Noise pollution29.What can we say about the research findings?A.Cities are generally 5.4F colder than rural areas.B.The length of daylight influences when trees start growing.C.Changeable water cycles may cause urban heat island effectD.Urban heat causes trees to green up 9 days earlier on average.30.What does the underlined word"mitigate"in the last paragraph mean?A.Relieve.B.Enhance.C.Establish.D.Release.31.In which section of a website can the text be found?A.Business.B.Education.C.Life kit.D.Environment.高三英语第5页(共10页)扫描全能王创建

第二节(共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填人空白处的最佳选项。选项中有两项为多余选项。Children are naturally curious beings,but getting them to study something theyaren't interested in can be a difficult task.Teachers and parents often find themselvesresorting to rewards in the form of stars,promises of high grades and wonderfulcareers,or threats of punishment.36Natural curiosity is sometimes referred to as"inner motivation".37 And it'seasy to understand why-it's difficult to study something we aren't engaged with,and ifwe're passionate about the information we're digesting,it feels more fulfilling.38 Praise and stimulation based on achieving good grades or fear of reprisal()has been acknowledged to motivate older students.However,it seems that at anearly age,it doesn't have as much effect.So,if it's the case that natural curiosity ismotivation for better learning,how can we stimulate that interest?According to some experts,39 Let the child see their learning as their freewill.If you want to teach a child to read,let them choose which book they use.Whether it's a graphic novel,TV guide or classic literature-the aim ofstimulating their appetite for reading is still met.Likewise,build a relationshipwith them as learners-listen to their negative feelings.Explain why an activity isvaluable,even if it isn't exactly fun.So it seems that the key to motivating children,especially the young ones,might comefrom stimulating that inner motivation.Maybe it's time to free them from the reigns ofthreats and rewards,40A.So it is crucial to promise and threaten children effectively.B.and give them a bit more choice of how they learn.C.But what if rewards and threats aren't the answer?D.and it can motivate the excellent children to learn well.E.Studies have found that children who see learning as fun and important arebetter at it.F.External motivation,things like rewards and punishment,does have its uses,too.G.the key is to allow some degree of autonomy and freedom.英语·试题卷二·第10页(共14页)
