九年级下第7周初中语文校本作业（提升练习）阅读下面的文字，完成1～6题。

(18分)枣花村李春雷①枣树，可能是春天里最后一个醒来的植物。

②惊蛰春分、清明谷雨，当春天铿铿锵锵地锣鼓喧天的时候，当百花争先恐后地粉黛登场的时候，当翠绿无孔不入地长满地球的时候，它却像一个慵懒的老农，穿着皂黑的粗布棉袄，依然蹲在墙根下打盹儿。

直到小满过后，它才睁开惺忪的双眸。

③然而，一旦醒来，便是厚积薄发，排山倒海。

④站在村头，远远望去，黄灿灿、雾腾腾，氤氤氲氲，宛若一片燃烧的火焰。

⑤走进小村，到处是奇形怪状的老枣树。

树身粗皴焦黑，却又新枝繁茂，葳葳蕤蕤。

每一根枝条上，缀满了清新嫩绿的鲜叶，在阳光中，羞羞的、颤颤的，明眸皓齿，流波送盼。

最是叶柄上结满的米粒大小的细碎黄花，若一盏盏．．．嘴巴，．．．纤手，似一张张．．．灯火，像一只只在清风中摇曳着、微笑着、歌唱着，咝咝咝．．．。

那是土地的呢喃，那是乡．．．、嗡嗡嗡．．．、嘤嘤嘤村的耳语，那是时令的梦靥……⑥一片片枣花凋谢了，在空中飘舞，仿佛漫天金屑，落在凹处，聚在墙角，静静喘息。

⑦闭上眼睛，沐浴香熏，那种醇厚和温热，若闻乡音，如归童年。

⑧2022年6月上旬的一天，我走进了邯山区小堤村。

这个小村，位于漳河故道腹地，独处偏僻。

该村祖先于明代从山西迁来，携带枣树幼苗，以赓续根脉。

枣树蘖根生长，更适宜这一方水土。

几百年来，家家户户、房前屋后，村内野外，处处枣树。

⑨哦，枣树，中国北方最地道的乡土树种。

⑩《诗经》曰“八月剥枣，十月获稻”；《韩非子》有枣栗赈济饥荒的记载；《战国策》中，苏秦曾言，枣栗之利，足实于民矣。

这些都说明，枣曾是北方的经济命脉，也是君王考量治国安邦的重要依据。

⑪两千多年来，枣树始终是北方乡村的经典记忆。

⑫唐朝诗人刘长卿写道“行过大山过小山，房上地下红一片”。

宋代诗人张耒笔下则别具画境：“枣径瓜畦经雨凉，白衫乌帽野人装。

”⑬当然，最著名者，还是苏轼。

“簌簌衣巾落枣花，村南村北响缫车”，更是写尽了枣花时节的田园风光。

B.“但悲不见九州同”与“九州生气恃风雷”中的“九州”指的都是中国。

C.《示儿》和《题临安邸》都讽刺了那些醉生梦死、不顾国计民生的南宋统治者。

D.《示儿》《题临安邸》《己亥杂诗》这三首诗的题目分别提到了人物、地点和时间。

our surroundings and even our identity．Reading good books is one of the greatest pleasures in life．It increases our contentment when we are cheerful，and lessens our troubles when we are sad．Whatever may be our main purpose in reading，our contact with good books should neverfail to give us enjoyment and satisfaction．With a good book in our hands we never feel lonely．Whether the characters described are taken from real life or are purely imaginary，they may become our companions and friends．In the pages of books we can walk with the wise and the good of all lands and all times．The people we meet in books may delight us either because they resemble human friends whom we hold dear or because they present unfamiliar types whom we are glad to welcome as new acquaintances（熟人）．Our human friends sometimes may bore us，but the friends we make in books never weary us with their company．By turning the page we can dismiss them without any fear of hurting their feelings．When human friends leave us，good books are always ready to give us friendship，sympathy，and encouragement．One of the most valuable gifts given by books is experience．Few of us can travel far from home or have a wide range of experiences，but all of us can lead varied lives through the pages of books．Whether we wish to escape from the seemingly dull realities of everyday life or whether we long to visit some far﹣off place，a book will help us when nothing else can．To travel by book we need no bank account to pay our way；no airship or ocean liner or stream﹣lined train to transport us；no passport to enter the land of our heart's desire．Through books we may get the thrill of dangerous adventure without danger．We can climb lofty mountains，brave the dangers of an Antarctic winter，or cross the scorching（赤日炎炎）sands of the desert，all without hardship．In books we may visit the studios of Hollywood；we may join the picturesque peasants in an Alpine village or the kindly natives on a South Sea island．Indeed，through books the whole world is ours for the asking．The possibilities of our literary experiences are almost unlimited．The beauties of nature，the enjoyment of music，the treasures of art，the triumphs of architecture，the marvels （令人惊叹）of engineering，are all open to the wonder and enjoyment of those who read．1.Why is it that we sometimes forget our surroundings and even our identity while reading？A．No one has come to disturb you．B．Everything is so quiet and calm around you．C．The book you are reading is so interesting and attractive．D．Your book is overdue；you are finishing it at a very fast speed．2.The word "weary" means．A．to attract someone's attentionB．to distract someone's attentionC．to make someone very boredD．to make someone interested3.Which one of the following statements is true？A．Your wish to visit some far﹣off place can be realized through the pages of the books．B．To escape from the dull realities of everyday life，you should take up reading．C．Books can always help you to live a colorful life．D．You may obtain valuable experience from reading good books．(B)Across the world，studies have consistently found that girls perform significantly better than boys in reading．These studies show that girls typically read more frequently than boys，and have a more positive attitude toward reading．There are several reasons that help explain these gender﹣based differences．Parents readmore with their daughters．This sends a strong and early message that books are for girls，as well as equipping girls with a significant advantage．Recent research has found even though boys read less frequently than girls，girls still receive more encouragement to read from their parents．So how can parents and educators help bridge this socially﹣engineered gap for boys' reading？To improve boys' reading performance，parents and educators may look for ways to connect boys with reading．This has led to discussion about the importance of promoting so ﹣called "boy﹣friendly" books that boys supposedly "prefer"．These are typically assumed to be non﹣fiction works，as many people believed that boys prefer to read non﹣fiction．But this belief is not supported by recent research，which in fact suggests boys are more likely to choose to read fiction than non﹣fiction．Encouraging all boys to read non﹣fiction under the mistaken belief that it is their preference may actually be harmful．Fiction readers read more frequently and demonstrate faster language learning and higher language ability．Besides encouraging more fiction reading，there are a number of ways that we can help connect boys with books．Firstly，don't assume that boys of the same age have the same interests or that their interests stay the same over time．To match boys with suitable reading material，have regular discussions about reading for pleasure in order to keep up with their interests．Schools should also provide access to libraries during lessons throughout the years of schooling．Girls visit the library in their free time more than boys，and as students move to higher grades they often have less access to libraries during class．Access to books for boys is essential to promote reading．In addition，we should keep paper books available because research shows that boys are less likely to choose to read on screens than girls．Finally we should promote reading as an enjoyable pastime by being a role model．Let your children or students see you read for pleasure．4.According to the author，what is the main cause of the difference in boys' and girls' readingability？A．Social factors．B．Teaching methods．C．Personal preferences．D．Psychological differences．5.Why does the author recommend that adults regularly talk to boys about reading？A．To persuade boys to read more often．B．To learn what boys are most interested in．C．To help boys improve their language ability．D．To show that adults are good reading role models．6.When should schools give students additional library access according to the author？A．Before and after class．B．At any time of the school day．C．At regular times during class．D．When they are in the lower grades．7.What is the main purpose of the text？A．To show students ways to improve their reading．B．To explain why boys are not as good at reading as girls．C．To urge governments to provide more reading resources．D．To provide strategies that can help improve boys' reading ability．【阅读表达】Daniel isn't doing well at school，and he is very busy. Every week, he has drum lessons, tennis lessons, chess club and swimming meets. Not surprisingly, he stays up late finishing his homework.

He is suffering from having too much to do.Keep in mind that school is your child's most important activity. If your child has too many outside activities, this constant running from one thing to the next gets in the way of school success. Help them choose two or three things they love doing. Three is enough.When they have too much to do, kids often appear to have emotional(情绪的) problems, learning problems, poor study skills or poor working habits. As a matter of fact, they just don't have time to do their homework, play or relax. It seems as if these kids are trying to squeeze(挤出)school into their busy schedules.Kids always do better at school and in everyday life if they aren't stressed out or too tired. When kids are stressed out，parents need to help check the amount of work and activities in and out of school.
