Ⅳ.阅读理解
(2016·广东深圳一模) One windy spring day, I observed young people having fun using the wind to fly their kites.Multicolored creations of varying shapes and sizes filled the skies like beautiful birds dashing and dancing in the exciting atmosphere above the earth.As the strong winds gusted against the kites, a string kept them in check.
Instead of blowing away with the wind, they arose against it to achieve great heights.They shook and pulled，but the controlling string and the clumsy tail kept them in tow (牵引)，facing upward and against the wind.As the kites struggled and trembled against the string，they seemed to say，“Let me go！Let me go！I want to be free！”They flew beautifully even as they fought the forced restriction of the string.Finally，one of the kites succeeded in breaking loose.“Free at last，”it seemed to say，“Free to fly with the wind.”
Yet freedom from control simply put it at the mercy of an unsympathetic gentle wind.It flew ungracefully to the ground and landed in a twisted mass of weeds and string against a dead bush.“Free at last”．Free to lie powerless in the dirt，to be blown
helplessly along the ground，and to settle down lifeless against the first roadblock.
How much like kites we sometimes are.There always exist misfortunes and restrictions, rules to follow from which we can grow and gain strength.Prohibition is a necessary counterpart to the winds of opposition.Some of us pulled at the rules so hard that we never fly fast to reach the heights we might have obtained.If we keep all the commandment (戒律), we will never rise high enough to get our tails off the ground.
Let us each rise to the great heights, recognizing that some of the prohibitions are actually the steady force that helps us climb and achieve.
A．many young people enjoying the sunny day
B．many birds dashing and dancing in the sky
C．many young people flying multicolored kites
D．the strong winds blowing against the sky
C[细节理解题。由第一段第一句．..I observed young people having fun using the wind to fly their kites.Multicolored creations of varying shapes and sizes filled the skies...可知，作者在看年轻人放风筝。故选C项。]
2．What didn’t happen to the freed kite?
A．It kept flying freely in the air.
B．It lay powerless in the dirt.
C．It was trapped in a dead bush.
D．It was blown helplessly around.
A[细节理解题。根据第三段第二句It flew ungracefully to the ground and landed in a twisted mass of weeds and string against a dead bush.可知，断线后的风筝没有继续飞行。故选A项]
3．What is the purpose of the author in writing this passage?
A．To give us tips on how to fly kites effectively.
B．To warn us that freedom is actually powerless.
C．To explain that restrictions are really unnecessary.
D．To teach us a lesson that rules are important in life.
D[推理判断题。由倒数第二段中的There always exist misfortunes and restrictions，rules to follow from which we can grow and gain strength.Prohibition is a necessary counterpart to the winds of opposition.以及最后一段中的．..some of the prohibitions are actually the steady force that helps us climb and achieve.可知。作者在文章最后表达了自己的感悟：人生中尽管有许多限制，但这正是我们得以稳步前进的动力。故选D项。]
4．Which of the following is the best title for the passage?
A．Fly with Restrictions.B．Where to Fly.
C．Why to Fly Kites. D．Fly to Freedom.
A[主旨大意题。文章最后两段中反复出现对restriction和prohibition的作用的论述，可知A项作为标题最能概括文章主旨。]

--文库出品-必属精品--文库出品-必属精品-- 高三语文考试 考生注意： 1．本试卷共150分。考试时间150分钟。 2．请将各题答案填在答题卡上。 3．本试卷主要考试内容：高考全部范围。 一、现代文阅读（35分） （一）论述类文本阅读（本题共3小题，9分） 阅读下面的文字，完成l～3题。 作者是文本的初始创造者，作者按文字规则和审美要求书写的能被公众阅读、欣赏、评论的语符系统便是文学作品。在语符系统中作者对外在世界的理解、自我生活的经验皆被对象化在文学作品之中并被作品显现，这就是作者的文本意图。文学作品是文学文本的基础和载体，它在文学阅读、欣赏、评论中成为文学文本。而作为文学本文基础和载体的文学作品也就独立于作者，它在对象化作家的主观世界的同时，成为客观独立的文本，不再为作者所控制和改变。。 阅读是极为复杂的精神意识和语言使用活动。而在阅读中，作品与读者则是一与多的关系，所以一千个读者就有一千个哈姆雷特。阅读具有个体心灵选择与心灵赋予的主观自由性。读者的这种主观自由性也使对一个文学作品的每一次阅读都具有独一无二性和不可重复性。文学阅读之所以是一种文本阐释活动而不是一般的认知活动，就在于读者在阅读文本时，作者的生活经历可以被理醉为读者当下的生活意义。读者通过对文本的阅读，与作者和作者创作的生活之间不仅达成一种认知的交往，而且实现了一种意义的确认。对文本的阅读也就成为对读者自己的意义的发现，对文本的阐释也就变为对读者所居生活的评说。 评者是一种特殊的读者。发现文本中的作者意图，判明读者意图的合理性，进而昭示评者的意图，从而释出文学文本意义，使一个具体的文学作品成为包括过去、现在和将来全部生活意义与人生价值的文化显现，实现文学文本对现实生活的超越，这些都是评者阅读文本、阐释文本的根本目的所在。 在马克思的文学评论中，人不是西方启蒙思想中观念的人，而是现实的人。在马克思所处的十九世纪的资本主义时代，现实的人是被物化奴役的个体人，也是推动社会发展的具体人，这正是马克思高度评价十九世纪英法现实主义小说成就的根本原因。同时，一些批评与理论实践在一定程度上受到了黑格尔逻辑主义批评观的影响。评论者认为每个文学文本中的意义都潜藏着支配一切文本意义的普遍规律，而且这种普遍规律贯穿在历史过程中。二十世纪五六十年代，阶级性、人民性等也因之成为文学评论的基本观念和普遍标准，在古代文学评论中就出现了“扬杜抑李”的现象。而二十世纪与二十一世纪之交，我国评论界又盛行以审美意义取代意识形态的批评观念，认为审美才是文学艺术的本质，出现了“贬鲁迅、赞周作人”的怪现象。 综上所述，文学文本的意义是作者创作、读者阅读、评者评论三者共同建构的。曾经作为历史的作品在当下的阐释中成为现在的文本。由此，民族文学的传承、外国文文学的借鉴不仅是发现、描述、说明，而且是当下文化的增值，现代意义义的深化，这样，文学活动将真正引导着人们自主地从现在走向未来。 （《摘编自张政文《文学文本的意义之源》）1．下列关于原文内容的理解和分析，正确的一项是（3分）（） A．文学作品中作者的文本意图是作者对外在世界的理解被对象化在文学作品之中并被作品显现。

第二部分：阅读理解（共两节，40分） 第二节（共5小题；每小题2分，共10分） 根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 Where did your family eat dinner last night? In the car on the way to sport? At McDonald’s? Or at the dinner table? A survey taken a few years ago found that 28% families ate dinner together at home seven nights a week. Another quarter said they ate together three or fewer nights a week. Once upon a time the situation was different. 51 Plates, forks and spoons would be laid out. As dinner time approached, an increasing number of hungry mouths would begin to appear with the question, “What’s for dinner”? 52The data seems to point to two main issues: overworked parents and overscheduled children. When mum or dad do get home in the evening, they are soon in the car again to send the children to soccer, music, tutoring, and a host of other events. This nightly ceremony around the dinner table is both vital and fruitful; it is what keeps a family together. Sure, the conversation is not always significant and children argue. And sometimes the deepest and most meaningful times in a family are not at the table at all. ___53___The dinner table is the place where a family builds an identity. Stories are passed down, jokes are exchanged and the wider world is examined through the lens（镜头）of a family’s values. Children pick up vocabulary and a sense of how conversation is structured. 54 Dinner time is “family time”. Coming back daily to the same place helps gain familiarity. The significance of dinner time is more than above. Studies show that the more families eat together, the less likely the children are to smoke, drink, get depressed, and develop eating disorders, and the more likely they are to do well in school and learn how to socialize. One professor a t Rutgers University in New Jersey stated, “A meal is about civilizing children.___55___” So start by planning some stay at home family dinners together. Just family talk. A. It’s a time to teach them to be a member of their culture. B. Each night the dining table would be set with a simple cloth.
