河北省部分学校2024-2025学年高三年级9月入学摸底考试语文试题一、现代文阅读(35分)( 一 )现代文阅读I (本题共5小题,19分)阅读下面的文字,完成下面小题。

材料一:马克思以前的唯物论,离开人的社会性,离开人的历史发展,去观察认识问题,因此不能了解认识对社会实践的依赖关系,即认识对生产和阶级斗争的依赖关系。

首先,马克思主义者认为人类的生产活动是最基本的实践活动,是决定其他一切活动的东西。

人的认识,主要地依赖于物质的生产活动,逐渐地了解自然的现象、自然的性质、自然的规律性、人和自然的关系;而且经过生产活动,也在各种不同程度上逐渐地认识了人和人的一定的相互关系。

一切这些知识,离开生产活动是不能得到的。

在没有阶级的社会中,每个人以社会一员的资格,同其他社会成员协力,结成一定的生产关系,从事生产活动,以解决人类物质生活问题。

在各种阶级的社会中,各阶级的社会成员,则又以各种不同的方式,结成一定的生产关系,从事生产活动,以解决人类物质生活问题。

这是人的认识发展的基本来源。

人的社会实践,不限于生产活动一种形式,还有多种其他的形式,阶级斗争,政治生活,科学和艺术的活动,总之社会实际生活的一切领域都是社会的人所参加的。

因此,人的认识,在物质生活以外,还从政治生活文化生活中,在各种不同程度上,知道人和人的各种关系。

马克思主义者认为人类社会的生产活动,是一步又一步地由低级向高级发展,因此,人们的认识,不论对于自然界方面,对于社会方面,也都是一步又一步地由低级向高级发展,即由浅入深,由片面到更多的方面。

在很长的历史时期内,大家对于社会的历史只能限于片面的了解,这一方面是由于剥削阶级的偏见经常歪曲社会的历史,另一方面,则由于生产规模的狭小,限制了人们的眼界。

人们能够对于社会历史的发展作全面的历史的了解,把对于社会的认识变成了科学,这只是到了伴随巨大生产力——大工业而出现近代无产阶级的时候,这就是马克思主义的科学。

一、现代文阅读(35分)(一)现代文阅读Ⅰ(本题共5小题,19分)阅读下面的文字,完成1~5题。

材料一:为了在有限的面积内构建富于变化的风景,苏州古典园林在布局上,采取了划分景区和空间的办法。

规模较大的园林把全园划分为若干区,各区都有风景主题和特色,这是我国古典园林创造丰富园景和扩大空间感的基本手法之一,不仅苏州古典园林如此,帝王苑囿如圆明园、颐和园、承德避暑山庄等也莫不如此。

不过景区的划分宜主次分明,曲折、开朗配合,使之富有变化和对比,既丰富又不琐碎。

由于一般山池所占面积较大,如把主要山池所在的一区作为全园的主要景区,再在周围配以若干次要景区,就不难达到上述效果,现存苏州各园基本上都运用了这种手法。

苏州许多园林又强调幽深曲折,所谓“景贵乎深,不曲不深”,讲的就是这种手法,因为曲折的布局可以增加园景的深度,避免一览无余的弊病。

自然式山水风景园必然产生不规则的平面,山池、道路、走廊、云墙等,蟠曲迂回,也利于造成曲折的布局。

为了增加园景深度,多数园林的入口处设有假山、小院、漏窗等作为屏障,适当阻隔视线,使人隐约看到一角园景,然后几经盘绕才能见到园内山池亭阁的全貌。

园内空间一环扣一环,庭院一层深一层,这都是在总平面布置中求其深度感的办法。

空间互相穿插贯通是增加园景深度和层次的重要手段。

相邻空间之间成半隔半开状态,使房屋、山林相互衬托,互为“借景”,可以形成丰富的层次。

拙政园中部和留园中部都是层次深远的良好例子,前者空间多开而少隔,后者以庭院为主,少开而多隔,形成两种不同的效果。

墙边院角,用走廊划出小院,疏点树石,或透过门洞、窗洞看到芭蕉、竹丛、树木、湖石,都是增加深度和层次的常用手法。

屋后、山后用高树、竹林、楼阁等穿插其间作为背景,使房屋山林向上层层推远,可以造成景外有景的印象。

留园中部从涵碧山房前西望土山,在树石亭廊后面还有枫林作背景,层次重叠高远;而由此北望,虽是园中主景,但山后别无他物衬托,因此景色浅近而少层次。

They weren’t like that before .“Dad! Pull over ! I want to 48 something out”I jumped off the truck and rushed to the bridge .

Bob stepped through, and immediately regretted it . He was standing in a dim low-ceilinged cave, the walls carved out of solid ice.There were five children there ,huddling(拥抱)together in corner ,their eyesfixed hopefully on his . They were dressed exactly as he was ,in pale sheepskin jackets and trousers ,with matching boots ,and caps pulled down over their ears .All of them were in their mid teens, and their faces, pinched(皱缩)as much by fear as with cold , seemed strangely familiar ,as though he had known them all his life .A girl with intense dark eyes nodded towards the end of the room. When he failed to respond, she nodded again , more urgently than before, her lips forming words soundlessly.He saw then what he should have seen earlier, a second door set low in the end wall. It was much smaller and far less noticeable than the first ,yet he felt drawn to it just the same . Or was he merely being encouraged by his silent companions? Another of them ,a timid boy, gave him a smile of encouragement, which was instantly reflected in all the other faces .He found it difficult to resist, as if this, after all ,was why he was here to help them out in their mysterious adventure . And under the pressure of their combined request, he bent down and crawled through the low opening .This time he emerged onto a windswept ledge(岩壁). Above him, dark grey clouds racked across an even grey sky Below—far below—lay a deserted valley heaped with slabs(厚片)of ice.51.When Bob entered the cave ,he knew that he .A.was welcomeB.was unwelcomeC.had frightened the children insideD.couldn’t leave the cave52.The children huddled together because they were .A.of one family B.trying to keep warmC.afraid of Bob D.determined to stay together53.The girl nodded towards the end of the cave because she .A.couldn’t speak Bob’s languageB.didn’t dare to speak to Bob.C.wanted Bob to know their situationD.was too hungry to speak54.Bob went through the second door because .A.the timid boy forced him to do soB.he found it too cold in the caveC.it led to a mysterious unknown placeD.the children wanted him to do so(B)A “blogger” is a person who writes on an Internet computer Web site called a “blog” .

It was widely seen as an upset because “Brokeback”had been winning all kinds of prizes ,from the Golden Bear in Venice ,to the Golden Globe and the Independent Spirit Awards ,and was seen by most observers as shoo-in for the highest Oscar.An anonymous(匿名的)posting on Sina com summed up what many moviegoers expressed in one way or another , “Now that Ang Lee has got all the big international awards, Zhang Yimou and Chen Kaige need not compete for the title of No. 1 Chinese Director anymore”Other voices were less congratulatory. Dayyan Eng, a Chinese American who started his filmmaking career in Beijing ,did not think “Brokeback” is as goodas “The Ice Storm” an Ang Lee film from 1997.Liu Miaomiao, a director of independent films, rationalized that Hollywood would not give the top award to “Brokeback” because of political reasons.Sai Ren ,a film critic with CCTV6 ,a film channel ,noted that Lee’s achievement had little to do with Chinese cinema .He suggested that people watch the show just to enjoy it .63.According to the passage ,Ang Lee is the first Chinese who .A.was awarded the Best Actor at the 78th Academy AwardsB.made a martial arts film in the worldC.won the Best Director in the World.D.won the Best Director Award at Oscar64.What does the underlined word “shoo-in” mean in the third paragraph?A.sharp arrow B.certain winnerC.fashionable film D.best picture65.It can be infrred from the passage that .A.“B rokeback Mountain” is not as good as “Crash”B.It is unfair that the Best Picture was given to “Crash”C.Observers laid great hope on “Brokeback Mountain” for the Best Picture D.It was a great upset that “Brokeback Mountain”had won all kinds of prizes 66.Which of the following may be the best title for the passage ?A.The Best Director Award Goes to Chinese.B.The 78th Academy AwardsC.“Brokeback Mountain” the Best FilmD.An Argument about Ang Lee(E)The challenge to drink to the limits of on e’s endurance has become a celebrated part of college life . In one of the most extensive reports on college drinking thus far ,a 1997Harvard School of Public Health study found that 43 percent of college students admitted binge drinking in the preceding two weeks (Defined as four drinks in a sitting for a woman and five for a man ,a drinking binge is when one drinksenough to risk health and well-being)Experts estimate that excessive drinking is involved in thousands of student deaths a year. And the Harvard researchers found that there has been a dramatic change in why students drink 39 percent drank “to get drunk”in 1993, but 52 percent had the same objective in 1997.“What has changed is the across-the-board acceptability of intoxication(喝醉),” says Felix Savino at UW-Madison . Many college students today see not just drinking but being drunk as their primary way of socializing”.The reason for the shift are complex and not fully understood .But researchers guess that it may have something to do with today’s instant-satisfaction life-style ——and young people tend to take into the extreme.While binge drinking isn’t always deadly ,it does have other ,wide-ranging effects . Academics is one area where it takes a heavy toll (something paid ,lost or suffered ).Perhaps because alcohol increases aggression and affects judgment, it is also related to 25 percent of violent crimes and roughly 60 percent of vandalism on campus .Facing the many potential dangers; college campuses are searching for ways to reduce binge drinking.67.Why has “binge drinking” caused widespread concern?A.Because it is directly responsible for the academic problem on campus.B.Because it has claimed many young lives every year.C.Because it has had harmful effects on the students’health and well-being.D.Because it is in close connection with school violence.68.We can infer from the passage that young people today .A.cherish their dream and are willing to work hard for it.B.value spiritual satisfaction over physical satisfaction.C.are idealistic and disillusioned by the stark reality.D.seek immediate satisfaction and indulge(放纵)themselves too much 69.The paragraphs following the passage most probably discuss .A.efforts taken by different schools to fight against binge drinkingB.the importance of banning alcohol at student events on campusC.how to change student s’ behaviorD.the possible consequences of binge drinking70.Students regard drinking and binge drinking as .A.tolerable B.acceptable C.necessary D.essential VI.Complete the gaps using the sentences given below. There is one extra sentence.You’re asked to put down the answers on the answer sheet.Einstein ,Leonardo Da Vinci ,Julius Caesar ,and Napoleon . What do these men have in common? They were all left-handed! Beginning early in history ,southpaws (left-handed people) have been feared ,neglected and punished (71) .For many years ,the use of the left hand was considered evil (72) .Because of this prejudice against the left ,left-handed people were forced to switch hands .This change caused many problems for lefties in school, which resulted in frustration, bad behavior ,and high drop-out rates : Maybe that is why lefties were considered as unintelligent . But this could not be further from the truth .To understand intelligence, we need to understand the brain. Researchers studying the brain have found differences in the left side and right side of the brain. Researchers believe that people who use more of the left side of their brain tend to be more intelligent. (73)However ,one study also showed that left-brain people tend to have worse memories.So which side of the brain do lefties use? Actually ,both . Right-handed people use the left side of the brain more ,whereas left-handed people use both sides of the brain almost equally (74) Therefore ,information can pass more efficiently from one side of the brain to the other .The left hemisphere of the brain controls speech ,language, writing, logic; mathematics, and science .The right hemisphere controls music ,art ,creativity perception and emotion. (75) A.It may actually contribute to a child’s excellence!B.The part connecting the two halves of the brain is usually larger in left-handed people.C.In fact ,the Latin word for “left” is “sinister”.D.Since lefties use both sides ,they are often both creative and scientific. E.But finally they are getting recognition for their achievements.F.They also tend to use language better and solve problems faster.VII.WritingWriting 1:请根据以下的说明,使用5个规范的英语句子描述全部所给的信息内容。
