2010年高现代文分类汇编
2010年高考语文试题分类汇编——现代文阅读（一）一、（10年全国卷Ⅰ）托物抒情1450阅读下面的文字，完成14~17题。
灯火萧萧乌黑油污的煤油灯，一经火柴点燃，便有了亮晃晃的“生命”。
“生命”是意义就是它会让你想起与它共处的那段时光。
生命的最简单意义可以是一个字：“动”！那昏黄的煤油灯的火舌，就是那样闪动着，那样引逗着你的眼，那样闪着古老的昏黄。
在胡兴村，这样的煤油灯不知与我们共处了多少年，小的时候们我们叫它“番仔油灯”。
番仔油和番仔火（火柴）一样，都是由洋人传来的。
番仔油的味道呛鼻难闻，打来的油通常都放在墙角不起眼的地方，煤油灯缺油的时候才提出来添加，小心翼翼的，一方面怕弄脏了衣物、桌子，一方面怕易燃的煤油引来祝融肆虐，回禄嚣张①家用的煤油灯主体是大约十公分高的玻璃瓶，外围有铝片为套，瓶口是一个铅皮的盖子，中间钻一个小洞，棉纱捻成的灯芯就插在这个洞里，灯芯可以一直伸向瓶底，将煤油汲吸上来，油润的灯芯，火柴一点就燃着了，昏黄摇曳的光芒，就这样温暖着我们的童年。
深夜的时候，面对这样一盏摇曳的灯火，仿佛可以根据古人促膝而谈，读一点诗词，雅兴随之而起，如果能翻阅几则“聊斋”，或许更增加一些古奥之趣，可惜，当时年纪小，只认识李白的铁杵、王冕的荷花！最温暖的当然不是这摇曳昏黄的灯光，而是灯光下两个相对的人影，一老一少，祖孙两人从“人初静”，守到夜更深，守着永夜，守着灯火，守着长长的一段祖孙相牵系的深情记忆，那是祖母无怨的爱，无尽的心，所有的怀念都从这样温馨的画面进入、泛起……当灯芯烧黑了，我们用个小竹片剔亮它，挑灯夜战原来就是这样的啊！那情景仿佛剪烛西窗一般，灯芯越烧越长，就要用小剪刀剪除碳化的那小小一截，光，就更亮了！煤油灯的火焰很容易将墙壁、屋梁熏黑，因此悬挂的地方一直是固定一处，不随便改换，以免房子到处留下乌黑的油烟。
那样的煤油灯，我们家好像只有三盏，人在客厅的时候，灯随我们在客厅，夜读如果是在祖母的房间，灯就随着我们过去。

2010年高考试题(北京卷)英语试卷及答案解析
2010年普通高等学校招生全国统一考试英语(北京卷)第二部分：知识运用(共两节，45分)第一节单项填空(共15小题；每小题l分，共15分)从每题所给的A、B、C、D四个选项中，选出可以填入空白处的最佳选项，并在答题卡上将该项涂黑。
2010年高考北京卷的单项填空15个小题涉及了时态语态（22、24、26、28）、虚拟语气（34）、情态动词（23）、非谓语动词（21、25）、名词性从句（31、32、33）、定语从句（27）、状语从句（30）、介词（29）、冠词（35）。
今年单选最大的特点是考点集中：动词相关考点八道题目；从句相关考点五道题目，只有两道细节考点。
具体如下：1、时态考点以四道题目（其中一道和被动语态相结合）位居榜首，这一点承习了去年的局面。
2、非谓语动词的两道题目都是对基本点的考查，分量显得略轻。
3、情态动词的考查设定在特定的情境中，没有任何悬念。
4、虚拟语气重出江湖。
以对话体给出，混合时间的虚拟句，有一定难度，考查学生对非真实条件句的整体把握。
5、名词性从句独放异彩，出题数量之多，覆盖面之广堪称往年之最。
宾语从句、表语从句、主语从句各出一道。
6、定语从句只有一道，但考查的不是基本点。
7、唯一的一道状语从句也不是对常见从属连词的考查。
8、从2006年开始，介词考点每年都会光顾北京卷，今年考的是常见介词的基本点。
21. at my classmates' faces, I read the same excitement in their eyes.A. LookingB. LookC. To lookD. Looked21. 答案：A考点：本题考查非谓语动词。
解析：look与句子主语I为主动关系，因此用looking.22. In the spoken English of some areas in the US, the "r" sounds at the end of the words .A. are droppedB. dropC. are being droppedD. have dropped22. 答案：A考点：时态和语态解析：the "r" sounds应该使用被动。

4、［参考答案］D［答案解析］D选项身临其境：亲自到了那个境地；第四段中，''带上特制的眼镜，你会发现自己置身坑内”符合语境，所以正确。
A选项，身不由己：身体不由自己作主;B选项，感同身受：心里很感激，就象自己亲身领受到一样。
现在多比喻虽未亲身经历，却如同亲身经历过一般;C选项，设身处地：设想自己处在别人的那种境地，指替别人的处境着想。
三项不符合语境所以错误。
5、［参考答案］D［答案解析］题干中'‘原来只有少数专家学者所识，现在走近了大众”意为以前很少人能够接触，现在大众都可以接触得到。

n+2+a n+3=4a n+1，④由②﹣（③+④）：﹣2a n=6a n﹣4a n﹣1﹣4a n+1，整理得：2a n=a n﹣1+a n+1，∴数列{a n}是等差数列．【考点】等差数列的通项公式，数列的应用，等差关系的确定，等差数列的性质【解析】【分析】（Ⅰ）由题意可知根据等差数列的性质，a n﹣3+a n﹣2+a n﹣1+a n+1+a n+2+a n+3=（a n﹣3+a n+3）+（a n+a n+2）+（a n﹣1+a n+1）═2×3a n，根据“P（k）数列”的定义，可得数列{a n}是“P（3）数列”；﹣2（Ⅱ）由“P（k）数列”的定义，则a n﹣2+a n﹣1+a n+1+a n+2=4a n，a n﹣3+a n﹣2+a n﹣1+a n+1+a n+2+a n+3=6a n，变形整理即可求得2a n=a n﹣1+a n+1，即可证明数列{a n}是等差数列．。

While many people learn English in the classroom, the vast majority of English learning takes place outside of it.36 , it is important to know how it is used in everyday life. One of the best things you can do is to read. First ask yourself what you enjoy reading in your native language. If the subject matter is interesting to you, you will he more likely to keep going. Read a variety of different media in English, from magazines to novels. 37 . New York Times takes a more formal approach to the English language than somebody's personal blog.Consider your English level when selecting reading material.38 , but do not frustrate yourself needlessly by selecting a complex text . You can choose to be a side-by-side reader, with the English text on one page and its translation on the other page, if you have only been studying English for a couple of years.39 . So do not look up every word you don't know as you read. It will only slow things down and make the reading process much less fun. Instead, rely on what you have already known. When you come across a difficult word or phrase，use context clues to guess at its meaning. Write down or underline any words or phrases you cannot figure out. When you have finished reading, go to your list of new words. Now you can get your dictionary and look them up one by one. 40 . You will be more likely to keep reading the interesting subject.A. Challenge yourselfB. To better understand a languageC. When you want to learn English, try New York TimesD. Turn them into flash cards, keep them in mind and use themE. Putting a dictionary at hand is a good way of learning EnglishF. Your reading goal is to briefly understand what the piece is sayingG.
