专题组合(七)语言文字运用+名句默写+实用类文本阅读(四)一、语言文字运用1.依次填入下列各句横线处的成语,最恰当的一组是()①上海福喜的过期肉事件,引发跨国连锁餐饮品牌供应体系的空前动荡,麦当劳一时陷入了________的困境。
②彭泽核电场项目目前________,进,则望江经济受损,百姓安全风险升级;退,则彭泽数十亿税收落空,江西电力紧张难解。
③由中国牵头筹组的亚投行获得广泛支持,成员遍及五大洲,美日因误判形势,________,处境十分尴尬。
A.进退维谷进退无据进退两难B.进退两难进退维谷进退无据C.进退维谷进退两难进退无据D.进退无据进退两难进退维谷解析本题考查正确使用词语(包括熟语)的能力。
进退维谷:无论是进还是退,都是处在困境之中。
形容处境艰难、进退两难。
进退两难:前进和后退都难。
比喻事情无法决定,因而难以行动。
进退无据:形容陷于困窘境地。
①说跨国连锁餐饮品牌供应体系的空前动荡,麦当劳陷入了困境,所以用“进退维谷”。
②是说彭泽核电场项目进和退的两种情况,所以用“进退两难”。
③美日处境十分尴尬,故选用“进退无据”。
答案 C2.下列各句中,没有语病的一句是()A.人口生态失衡会破坏社会发展的稳定性和经济发展的持续性,因此,我国人口发展方式需要实现由数量控制型到生态优化型的战略转变。
B.“互联网+”本身是开放的产物,生物链和产业链开放,技术和资源共享,激发了人们创新创业的激情,催生了互联网经济现象的出现。
C.在经济发展新常态下,面对劳动力数量逐渐减少的现实,不再是国家简单地依靠大量的劳动力,而是用质量的提升来弥补数量的短缺。
D.按照法律规定,从事食品经营需要获得许可,但是目前一些网络食品经营者并没有取得资质,今后需要加大在这方面的规范和管理。
解析本题考查辨析并修改病句的能力。
了解语病的类型,根据语法辨析。
B 项,“催生了……的出现”句式杂糅,删去“的出现”;C项,成分残缺,应把“国家”提到“不再是”之前,让“国家”成为整个句子的主语;D项,“加大……规范和管理”搭配不当,改为“加强……规范和管理”。
答案 A3.填入下面一段文字横线处的语句,最恰当的一句是()美和实际人生有一个距离,________。
这如同生长在西湖或峨眉的人除了以居近名胜自豪以外,心里往往觉得西湖和峨眉实在也不过如此,而初看到西湖、峨眉的北方人却惊讶于它们的奇景。
这全是观点和态度的差别。
就好比乘海船遇着海雾,只知它妨碍呼吸,只嫌它耽误程期,预兆危险,没有心思去玩味它的美妙。
持实用的态度看事物,它们都只是实际生活的工具或障碍物,都只能引起欲念或嫌恶。
要见出事物本身的美,我们一定要从实用世界跳开,以“无所为而为”的精神欣赏它们本身的形象。
A.所以我们要缩小这种距离,真正看到事物本身的美B.只有与事物近距离接触,才能真正看到事物本身的美C.只有把事物摆在适当的距离之外去看,才能见出事物本身的美D.只要把事物摆在适当的距离之外去看,就能见出事物本身的美解析本题考查选用句式的能力。
首先要把握语段,这一段是表述如何才能见出事物本身的美。
第一句是先提出观点的总括句,之后作了类比说明,最后是举例分析原因。
解答时可以根据“这如同生长在西湖或峨嵋的人除了以居近名胜自豪以外,心里往往觉得西湖和峨嵋实在也不过如此,而初看到西湖、峨嵋的北方人却惊讶于它们的奇景”一句分析应填内容,A项,“这种”一词太突兀,可以排除;B项,“近距离接触”错误,可以排除;D项,“只要……就”关联词语表达的太绝对,因而也可排除,故答案可以确定为C项。
答案 C4.在下面一段文字横线处补写恰当的语句,使整段文字语意完整连贯,内容贴切,逻辑严密,每处不超过15个字。
自动驾驶汽车到底可不可行?近年来,人们对这一问题的兴趣越来越大。
数据显示,交通事故是人类死亡十大杀手中唯一的非疾病原因,而98%的交通事故由人为错误造成;此外,预计到2050年城市内交通拥堵时间将翻一倍。
由此,人们认为__①__的理由是:__②__,而且能为人们节省时间。
但是,让没有感情的机器开车,把自己的生命安全交给机器,__③__。
最近对德国民众的调查显示,60%的人不愿意尝试自动驾驶。
答:①__________________________________________________________②______________________________________________________________③______________________________________________________________解析本题考查语言表达简明、连贯、得体、准确、鲜明、生动的能力。
整体阅读,把握话题中心。
“自动驾驶汽车到底可行不可行”,接着阐述交通事故错误原因来揭示观点,自动驾驶汽车可行。
①处应是观点。
②处阐述理由,形式与后句形成递进。
“不仅……而且”,内容上应围绕前文归纳的“交通事故”来归纳内容,应为“不仅降低交通事故发生率”。
③处通过“但是”可知,人们是不愿意接受的,再由末句“60%的人不愿意尝试自动驾驶”可知,此处应为“多数人不能接受”。
答案①自动驾驶汽车可行②不仅可以大大降低交通事故发生率③多数人不能接受(或“需考虑人们的承受能力”)5.阅读下面的图表,完成后面的题目。
表一你认为网络实名制对于保障网络安全重要吗?表二你的网络注册名是实名吗?(1)请简要概括以上两个表格的内容。
(不能使用数字作答)答:____________________________________________________________________________________________________________________________ (2)请谈谈你对“网络实名注册”的看法。
答:____________________________________________________________________________________________________________________________解析本题考查图文转换及语言表达简明、连贯、准确的能力。
回答问题,注意把握给出的数据之间的关系和体现的意义。
第一问,通过观察数据,客观描述数据传达的信息,抓住81.6%和76.5%两个重点数据作答。
注意题目要求,不能出现数字。
第二问,主观性较强,可结合现实生活作答,谈实名制的作用,言之有理即可。
答案(1)大多数人认为网络实名制对于保障网络安全很重要,但在现实生活中大多数人又没有践行网络实名制。
(2)优点:对打击网上违法犯罪活动、减少网络暴力、净化网络环境、监督公共言论、规范网民行为、强化网民责任意识、推动诚信社会建设,起到了积极作用。
缺点:网络本是一个可以自由发表见解的地方,实名制可能导致人们因为过于担心因言论不当被惩罚,而不敢公开发表言论、传播信息。
同时,如果网民的信息安全得不到保护,难免会被不法之徒盗用和滥用。
互联网的发展要求管理体系与时俱进,信息安全则是基石。
只有加强信息保护,才能更好地推进网络发展。
二、名句默写6.补写出下列句子中的空缺部分。
(1)《诗经·氓》中的女主人公解释自己不肯答应婚嫁的原因的两句是“________________,________________。
”(2)李白在《蜀道难》一诗中引用神话传说为其增添了浪漫气息,如引用“五丁开山”神话的句子是“________________”。
(3)《曹刿论战》中,针对国君将衣食与百姓共享的做法,曹刿的评价是:________________,________________。
解析本题考查默写常见的名句名篇的能力。
默写考查的是学生对古代诗歌散文的理解能力,这要求学生既能理解诗词文章抒发的情感,又能准确书写。
本题涉及的“匪我愆期、小惠未徧”等字需要特别注意。
答案(1)匪我愆期子无良媒(2)地崩山摧壮士死(3)小惠未徧民弗从也三、实用类文本阅读阅读下面的文字,完成7~9题。
湖畔的梭罗汪家明梭罗这样的人,是人类的异端,唯其异端,才展示出奇才,就像梵高,其极端的行事他人难能仿效,但却会被后人奉为至尊。
在美国,梭罗(1817-1862)算是古典的作家,是美国文学的开创者之一。
在哈佛大学读书期间,梭罗就得以亲近爱默生,经常参加爱默生家的文人聚会,受其超验主义观点的影响,反对权威,提倡个性的绝对自由;崇尚直觉,认为人能超越感觉和理性直接认识真理。
爱默生也喜欢这个年轻人,曾致信哈佛总裁推荐梭罗,使梭罗获得奖学金。
1845年春,他决心进行向往已久的生活实验。
在征得爱默生同意后,他在离村镇不远的瓦尔登湖畔属于爱默生的林地上,着手自建木屋,并于7月4日搬进新居,独自在此居住26个月之久,基本上过着自给自足的生活。
他自己垦荒种植,自己伐木劈柴烧壁炉,自己做饭,用自己生产的豆子换取必需的日用品,还给人帮工。
他追求“一周里只有一天工作,而有六天自由支配”的生活。
这些自由支配的时间,他用来会友交谈,用来参加文人聚会,更以绝大多数时间用来观察自然、沉思冥想、读书写作。
在湖畔小屋居住期间,他因多年拒付不合理的人头税而被捕,虽然第二天就由姑姑代缴被释放,但对他刺激极深,几年后发表了一篇名为《对政府的抵抗的文章》。
这篇文章被编入论文集时,改名为《论公民的不服从权利》,对后世产生了不可估量的影响,比如甘地的“不合作运动”、托尔斯泰的“勿抗恶主义”等,其精神实质都源于这篇文章。
这倒是梭罗生前难以想象的。
离开湖畔小屋后,除了偶尔做一点勘测工作,他基本过着自由撰稿人的生活,旅行、读书、记笔记、写作是其主要内容。
他喜欢数学,有测量的特长。
他养成了一种习惯:测量有兴趣的物件的大小与距离,如树的大小,池塘与河流的深度和宽度,山的高度等。
从1855年起,他开始感到身体不适,双腿发软,虽经积极治疗,一直没有痊愈,于1862年因肺结核发作去世,年仅四十五岁。
对他的作为和个性,朋友们有许多记录。
他一生放弃了太多东西:没有学着从事任何职业;没有结过婚;独自一人居住;不去教堂;不参加选举;拒绝向政府纳税;不吃肉,不喝酒,也从来没吸过烟。
在生活中他用不着抵抗什么诱惑。
但在其他方面,他却细如毫发。
据说,他在池塘边找到一种花,仔细观察后,断定它已经开了五天。
他胸前的口袋里有一本日记簿,上面记录了树林里应当在这一天开花的所有植物的名字;他知道某一个夜晚在河面上纷飞着地蝇,鱼们抢着吞食,吃得太饱,有些鱼竟胀死了。
他有种倾向:要放大这一刹那。
即便只是一个极小的物件,他也要从中看出自然界的定律。
梭罗生前只出版了两本书。
一本是他在1849年自费出版的《康科德河和梅里麦克河上的一星期》,内容是记录他和约翰在两条河上的旅行,其中穿插着大段大段文史哲和宗教方面的议论,晦涩难懂,没有引起什么反响。
