必修一第四单元检测 2016.9 高一语文备课组 一、选择题。（共 60 分，每道题 3 分） （一）《静女》 1.下列有关文学常识的叙述，错误的一项是( ) A.《诗经》是我国最早的一部诗歌总集，被儒家列为五部经典著作之首。 B.《诗经》中的诗歌分为“风”、“雅”、“颂”三个部分。“风”又叫“国风”共有15国风，160篇。大都是劳动人民创作的民间歌谣；“雅”分为大雅.小雅，共105篇，大多为周代宫廷乐曲歌辞：“颂”分为周颂、鲁颂、商颂，多为周天子及诸侯们祭礼时的乐歌，共40篇。 C.《诗经》反映了从西周到春秋时期的社会生活，共305篇，古时也称为“诗三百”。其创作方法基本上是浪漫主义的。 D.《诗经》中以四言诗为主，普遍采用赋、比、兴的表现手法。 2.阅读《邶风·静女》，完成（1）～（5）题。 (1）对这首诗词句的理解，不正确的一项是( ) A．题目“静女”，是指文静美丽的姑娘。 B．“爱而不见”的意思是说故意藏起来不出现，逗小伙子着急。 C．“说怿女美”的意思是指姑娘美丽的彤管映衬得你更美。 D“自牧归荑，洵美且异”这两句称赞姑娘送给他的荑草实在美得出奇。 (2）对这首诗的赏析，不恰当的一项是( ) A．这首诗基调欢快而富有情趣，叙写了一对青年男女约会的过程。 B．“爱而不见，搔首踟蹰”这个细节惟妙惟肖地描绘了小伙子当时那种焦灼不安的情态。 C．无论是赠彤管，还是赠荑草，都发生在同一天，可见这对青年男女的恋情已到极致。 D．这首诗除了细节描写外，还运用了双关及移情手法，因而生动活泼．富有情趣。 （3）选出对《静女》一诗内容理解有误的一项是（） A．《静女》是一首赋体诗，它运用“直陈其事”的手法，采用三章连唱的形式来叙写故事，感情回环往复，内容富于变化，充分体现了民族的特色。 B．本诗以生动的语言，风趣的细节，表现了一对男女青年热恋中的情趣，人物神形毕现，呼之欲出。
数列 1．1数列的概念 预习课本P3～6，思考并完成以下问题 (1)什么是数列？数列的项指什么？ (2)数列的一般表示形式是什么？ (3)按项数的多少，数列可分为哪两类？ (4)数列的通项公式是什么？数列的通项公式与函数解析式有什么关系？ [新知初探] 1．数列的概念 (1)定义：按一定次序排列的一列数叫作数列． (2)项：数列中的每一个数叫作这个数列的项． (3)数列的表示：数列的一般形式可以写成a1，a2，a3，…，a n…，简记为数列{a n}．数列的第1项a1，也称首项；a n是数列的第n项，也叫数列的通项． [点睛] (1)数列的定义中要把握两个关键词：“一定次序”与“一列数”．也就是说构成数列的元素是“数”，并且这些数是按照“一定次序”排列的，即确定的数在确定的位置． (2)项a n与序号n是不同的，数列的项是这个数列中的一个确定的数，而序号是指项在数列中的位次． (3){a n}与a n是不同概念：{a n}表示数列a1，a2，a3，…，a n，…；而a n表示数列{a n}中的第n 项． 2．数列的分类 项数有限的数列叫作有穷数列，项数无限的数列叫作无穷数列．
3．数列的通项公式 如果数列{a n }的第n 项a n 与n 之间的函数关系可以用一个式子表示成a n ＝f (n )，那么这个式子叫作数列{a n }的通项公式． [点睛] (1)数列的通项公式实际上是一个以正整数集N ＋或它的有限子集{1,2,3，…，n }为定义域的函数解析式． (2)同所有的函数关系不一定都有解析式一样，并不是所有的数列都有通项公式． 4．数列的表示方法 数列的表示方法一般有三种：列表法、图像法、解析法． [小试身手] 1．判断下列结论是否正确．(正确的打“√”，错误的打“×”) (1)同一数列的任意两项均不可能相同．( ) (2)数列－1,0,1与数列1,0，－1是同一个数列．( ) (3)数列中的每一项都与它的序号有关．( ) 答案：(1)× (2)× (3)√ 2．已知数列{a n }的通项公式为a n ＝1－(－1)n ＋1 2，则该数列的前4项依次为( ) A ．1,0,1,0 B ．0,1,0,1 C.12，0，1 2 ，0 D ．2,0,2,0 解析：选B 把n ＝1,2,3,4分别代入a n ＝1－(－1)n ＋ 12中，依次得到0,1,0,1. 3．已知数列{a n }中，a n ＝2n ＋1，那么a 2n ＝( ) A ．2n ＋1 B ．4n －1 C ．4n ＋1 D ．4n 解析：选C ∵a n ＝2n ＋1，∴a 2n ＝2(2n )＋1＝4n ＋1. 4．数列1,3,6,10，x,21，…中，x 的值是( ) A ．12 B ．13 C ．15 D ．16 解析：选C ∵3－1＝2,6－3＝3,10－6＝4， ∴? ???? x －10＝5，21－x ＝6，∴x ＝15. [典例] (1){0,1,2,3,4}；(2)0,1,2,3；(3)0,1,2,3,4，…； (4)1，－1,1，－1,1，－1，…；(5)6,6,6,6,6. [解] (1)是集合，不是数列；

必修一第四单元古典诗歌（一） 静女 静女其姝，俟我于城隅。 爱而不见，搔首踟蹰。 静女其娈，贻我彤管。 彤管有炜，说怿女美。 自牧归荑，洵美且异。 匪女以为美，美人之贻。 氓 氓之蚩蚩，抱布贸丝。匪来贸丝，来即我谋。送子涉淇，至于顿丘。匪我愆期，子无良媒。将子无怒，秋以为期。 乘彼垝垣，以望复关。不见复关，泣涕涟涟。既见复关，载笑载言。尔卜尔筮，体无咎言。以尔车来，以我贿迁。 桑之未落，其叶沃若。于嗟鸠兮，无食桑葚！于嗟女兮，无与士耽！士之耽兮，犹可说也。女之耽兮，不可说也。 桑之落矣，其黄而陨。自我徂尔，三岁食贫。淇水汤汤，渐车帷裳。女也不爽，士贰其行。士也罔极，二三其德。 三岁为妇，靡室劳矣；夙兴夜寐，靡有朝矣。言既遂矣，至于暴矣。兄弟不知，咥其笑矣。静言思之，躬自悼矣。 及尔偕老，老使我怨。淇则有岸，隰则有泮。总角之宴，言笑晏晏。信誓旦旦，不思其反。反是不思，亦已焉哉！
15离骚（节选） 屈原 纷吾既有此内美兮，又重之以修能。扈江离与辟芷兮，纫秋兰以为佩。汨余若将不及兮，恐年岁之不吾与。朝搴阰之木兰兮，夕揽洲之宿莽。日月忽其不淹兮，春与秋其代序。惟草木之零落兮，恐美人之迟暮。不抚壮而弃秽兮，何不改乎此度? 乘骐骥以驰骋兮，来吾道夫先路！ 17汉魏晋诗三首 迢迢牵牛星 迢迢牵牛星，皎皎河汉女。 纤纤擢素手，札札弄机杼。 终日不成章，泣涕零如雨。 河汉清且浅，相去复几许？ 盈盈一水间，脉脉不得语。
短歌行 曹操 对酒当歌，人生几何？譬如朝露，去日苦多。 慨当以慷，忧思难忘。何以解忧？惟有杜康。 青青子衿，悠悠我心。但为君故，沉吟至今。 呦呦鹿鸣，食野之苹。我有嘉宾，鼓瑟吹笙。 明明如月，何时可辍？忧从中来，不可断绝。 越陌度阡，枉用相存。契阔谈宴，心念旧恩。 月明星稀，乌鹊南飞。绕树三匝，何枝可依？ 山不厌高，水不厌深。周公吐哺，天下归心。 归园田居 陶渊明 少无适俗韵，性本爱丘山。误落尘网中，一去三十年。羁鸟恋旧林，池鱼思故渊。开荒南野际，守拙归园田。方宅十余亩，草屋八九间。榆柳荫后檐，桃李罗堂前。暧暧远人村，依依墟里烟。狗吠深巷中，鸡鸣桑树颠。户庭无尘杂，虚室有余闲。久在樊笼里，复得返自然。
