人教部编版六年级下册语文期末复习非连续性文本阅读专项训练(一)(含答案)

六年级下语文小升初非连续性文本阅读专项训练一一、阅读非连续性文本,完成练习。

材料一:元宵上市,春节的又一个高湖到了。

正月十五,处处张灯结彩,整条大街像是办喜事,红火而美丽。

有名的老铺都要挂出几百盏灯来,各形各色,有的一律是玻璃的,有的清一色是牛角的,有的都是纱灯,有的通通彩绘全部《红楼梦》或《水水浒传》故事。

这在当年,也是一种广告。

灯一悬起,任何人都可以进到铺中参观。

晚上灯中点上烛,观者就更多。

材料二:中国的年画色解艳,文化内函キ富,具有极高的艺本价值。

春节来临之际,家家户户在门上张贴年画,借此寄托人们对风调雨顺、家和人顺的新盼。

材料三:风等是中国人发明的。

相传墨程以木头制成木鸟,研制三年而成,这是人类最早的风筝。

后来,其学生鲁班用竹子改进墨翟的风等材质,演进成今日的多线风争。

当今我国的放风筝活动,在发展旅游事业、对外文化交流、加强与世界各国人民友谊等方面发挥着重要作用。

材料四:剪纸是中国古老的民间艺术,它题材广泛,造型生动活波,是中国民间艺术百花圆中的一朵奇葩。

剪纸往往选择福禄寿诞、五谷丰登等题材,寄托人们对美好生活的向往。

材料五:戏曲是中国传統的戏剧形式,历史悠久。

据不完全统计,我国的戏曲种类,约有三百六十多种,传统剧目数以万计。

比较流行的剧种有京剧、昆曲、越剧、刷等五十多个,龙以京剧流行最广,適及全国,不受地区所限。

1.请用简洁的语言概括材料一的主要内容。

2.下列是材料一的前三句话的中心词,你认为最不合适的一项是()A. 元宵上市张灯结彩各形各色B.春节高潮红火美丽各形各色C. 元宵上市张灯结彩几百盏灯D.春节高潮办喜事彩绘故事3.画波浪线的句子里有四个词语意思相似,分别是、、和。

4.材料二、三、四、五分别介绍了中国的年画、风筝和。

5.将上面五则材料作为板报的内容,要取一个好的标题,下面哪个最合适...?()A.元灯市寓意多B.民间艺术在元宵C.中国老玩意儿得传承D.中国民间传统艺术6.在一场以“民间艺术该不该保留”为主题的辩论赛中,你作为观点为“民间艺术该保留”的正方,请根据以上材料写一段词。

期末复习选择题练习(一)

期末复习选择题练习(一)一.选择题1.下列说法中正确的是() [单选题] *A.当车从高架桥上通过时,桥面没有发生形变B.当你对一个物体施力时,你一定也受到这个物体对你力的作用(正确答案) C.彼此接触的物体之间一定有力的作用D.只有当物体发生形变时,才能说明它受到了力的作用答案解析:当车从高架桥上通过时,对桥面有压力,桥面会发生形变,故A错误;物体间力的作用是相互的,当你对一个物体施力时,你也会受到物体对你的力,故B正确;彼此接触的物体之间不一定有力的作用,例如将水平面上竖直放置的两个长方体靠在一起,虽然接触,但两物体之间没有力的作用,故C错误;力的作用效果有两个,一是改变物体的形状,二是改变物体的运动状态,所以当物体的运动状态发生改变时,也能说明它受到了力的作用,故D错误。

2.如图所示的现象中,主要说明力可以改变物体形状的是() [单选题] *A.(正确答案)BCD答案解析:小桌将海绵压变形,小桌的压力改变了海绵的形状,故A正确;铁球在磁铁的吸引下运动路径变弯,磁铁对铁球的吸引力使铁球的运动方向发生了改变,属于力改变物体的运动状态,故B错误;守门员接住足球,改变了球的运动状态,故C错误;运动员用力将标枪掷出,改变了标枪的运动状态,故D错误。

3.如图所示,在东京奥运会男子200米混合泳决赛中,中国选手汪顺以1分55秒的成绩成功夺冠!关于游泳过程,下列说法中错误的是()[单选题] *A.汪顺向后划水的力大于水对他的作用力(正确答案)B.汪顺与水之间的作用力是相互的C.使汪顺向前运动的力的施力物体是水D.力改变了汪顺的运动状态答案解析:汪顺游泳过程中,他的手和脚向后划水,对水施加向后的力,由于物体间力的作用是相互的,水就会对手和脚施加向前的反作用力,人就向前运动,所以汪顺向后划水的力和水对汪顺的力是一对相互作用的力,大小相等,故A错误、B 正确;水对汪顺的力使汪顺向前运动,所以施力物体是水,故C正确;水的推力使汪顺向前运动,改变了他的运动状态,故D正确。
