Sometimes online shopping isn't as good as we think. You can't see the products or check the quality (质量) and some people on the Internet aren't so honest (诚实的). And paying over the Internet isn't always safe. So you must be careful when shopping online. What should you do?First, try to find an honest shop. Usually this kind of online shop has good products and great service (服务). But if all customers (顾客) say the shop is “pretty good”,you should also be careful. None of the shops can make every customer happy. So __▲__.Second, compare products before really buying. In different shops, compare theprice, quality and service. Something expensive on the Internet isn't always good. You should choose the good product.Third, have a right way to pay. It's not always safe to pay through the bank card.

人教版七年级数学下册第5章《相交线与平行线》单元测试卷(解析版)
人教版七年级数学下册第5章《相交线与平行线》单元测试卷一.选择题1.下列说法,正确的是( )A. 若ac=bc,则a=bB. 两点之间的所有连线中,线段最短C. 相等的角是对顶角D. 若AC=BC,则C是线段AB的中点【答案】B【解析】【分析】根据等式的性质可判断A的正误;根据线段的性质判断B的正误;根据对顶角的性质判断C的正误;根据中点的性质判断D的正误.【详解】解:A、若ac=bc(c≠0),则a=b,故此选项错误,B、两点之间的所有连线中,线段最短,说法正确,故此选项正确,C、相等的角是对顶角,说法错误,应是对顶角相等,故此选项错误,D、若AC=BC,则点C是线段AB的中点,说法错误,应是若AC=BC=AB,则点C是线段AB的中点,故此选项错误,故选:B.【点睛】此题主要考查了等式的性质、对顶角的性质、线段的性质、中点,关键是熟练掌握课本基础知识,牢固掌握定理.2.如图,AB∥CD,点E在线段BC上,若∠1=40°,∠2=30°,则∠3的度数是( )A. 50°B. 55°C. 60°D. 70°【答案】D【解析】【分析】先根据平行线的性质求出∠C的度数,再由三角形外角的性质即可得出结论.【详解】∵AB∥CD,∠1=40°,∠2=30°,∴∠C=40°.∵∠3是△CDE的外角,∴∠3=∠C+∠2=40°+30°=70°.故答案选D.【点睛】本题考查的知识点是平行线的性质,解题的关键是熟练的掌握平行线的性质.3.如图,将含30°角的直角三角板ABC的直角顶点C放在直尺的一边上,已知∠A=30°,∠1=40°,则∠2的度数为( )A. 55°B. 60°C. 65°D. 70°【答案】D【解析】【分析】根据平行线的性质求出∠3=∠1=40°,根据三角形的外角性质求出∠2=∠3+∠A,代入求出即可.【详解】∵EF∥MN,∠1=40°,∴∠1=∠3=40°.∵∠A=30°,∴∠2=∠A+∠3=70°.故选D.【点睛】本题考查了平行线的性质,三角形外角性质的应用,能求出∠3的度数是解答此题的关键,注意:两直线平行,内错角相等.4.图中的∠1、∠2可以是对顶角的是( )A. B.C. D.【答案】C【解析】【分析】根据对顶角的定义,具有公共顶点且角的两边互为反向延长线对各图形分析判断后进行解答.【详解】解:A、∠1与∠2不是对顶角,B、∠1与∠2不是对顶角,C、∠1与∠2是对顶角,D、∠1与∠2不是对顶角,故选:C.【点睛】本题主要考查了对顶角的定义,熟练掌握定义是解题关键.5.如图,若AB,CD相交于点O,∠AOE=90°,则下列结论不正确的是( )A. ∠EOC与∠BOC互为余角B. ∠EOC与∠AOD互为余角C. ∠AOE与∠EOC互为补角D. ∠AOE与∠EOB互为补角【答案】C【解析】【分析】直接利用垂直的定义结合互余以及互补的定义分析得出答案.【详解】解:∵∠AOE=90°,∴∠BOE=90°,∵∠AOD=∠BOC,∴∠EOC+∠BOC=90°,∠EOC+∠AOD=90°,∠AOE+∠EOB=180°,故A、B、D选项正确,C错误.故选:C.【点睛】此题主要考查了垂直的定义、互余以及互补的定义,正确把握相关定义是解题关键.6.已知:如图,直线BO⊥AO于点O,OB平分∠COD,∠BOD=22°.则∠AOC的度数是(

(21分)人类的悲剧......没过多久,他们发现雪地上插着一根滑雪杆,上面绑着一面黑旗,周围是他人扎过营地的残迹——滑雪板的痕迹和许多狗的足迹。
在这严酷的事实面前也就不必在再怀疑:阿蒙森在这里扎过营地了。
千万年来人迹未至,或者说,太古以来从未被世人敲击过地球的南极点竟在极短的时间之内——即一个月内两次被人发现,这时人类历史上闻所未闻、最不可思议的事。
而他们恰恰是第二批到达的人,他们仅仅迟到了一个月。
虽然昔日逝去的光阴数以几百万个月计,但现在迟到的这一个月,却显得太晚太晚了——对人类来说,第一个到达者拥有一切,第二个到达者什么也不是。
一切努力成了徒老,历尽千辛万苦显得十分可笑,几星期,几个月,几年的希望简直可以说是()。
“历尽千辛万苦,无尽的痛苦烦恼,风餐露宿——这一切究竟为了什么还不是为了这些梦想,可现在这些梦想全完了。
”斯科特在他的日记中这样写道。
泪水从他们的眼睛里夺眶而出。
尽管筋疲力竭,这天晚上他们还是夜不成眠。
他们像被判了刑似的时期希望,()地继续走着那一段到极点去的最后路程,而他们原先想的是:欢呼着冲向那里。
他们谁也不想安慰别人,只是默默地拖着自己的脚步往前走。
1月18日,斯科特海军上校和他的四名伙伴到达极点。
由于他已不再是第一个到达这里的人,所以这里的一切并没有使他觉得十分耀眼。
他只用冷漠的眼睛看了看这块伤心地地方。
“这里看不到任何东西,和前几天令人()的单调没有任何区别。
”这就是罗伯特.福尔肯.斯科特关于极点的全部描写。
他们在那里发现的惟一不寻常的东西,不是由自然界造成的,而是由角逐的对手造成的,那就是飘扬着挪威国旗的阿蒙森的帐篷。
挪威国旗耀武扬威,洋洋得意地在这被人类冲破的保垒上猎猎作响。
它的占领者还在这里留下一封信,等待着这个不相识的第二名的到来,他相信这第二名一定会随他之后到达这里,所以他请他把这封信带给挪威的哈康国王。
斯科特接受了这项任务,他要忠实的去履行这一最冷酷无情的职责:在世界面前为另一个人完成的业绩作证,而这一事业正是他自己所热烈追求。
14.请用一句话概括选文的主要内容。
(4分)15.填入上文括号中最恰当的一组词语是().(3分)A.癫狂闷闷不乐惊讶不已B.发狂无可奈何惊慌失措C.疯狂镇定自若毛骨悚然D.癫狂闷闷不乐毛骨悚然16.他要忠实的去履行这一最冷酷无情的职责:在世界面前为另一个人完成的业绩作证,而这一事业正是他自己所热烈追求。
斯科特为什么要去履行这一最冷酷无情的职责这一行动表现了他怎样的风度和品格(6分)17.挪威国旗耀武扬威,洋洋得意地在这被人类冲破的保垒上猎猎作响,国旗怎会耀武扬威洋洋得意这句话体现了斯科特怎样的复杂感情(4分)18.有人说成功只是一种结果,选文也提到对人类来说,第一个到达者拥有一切,第二个到达者什么也不是,你是否同意这种看法请联系本文内容说说你的认识。
(6分)(三).阅读下面的文章,完成文后各题。
(21分)如果想做一颗大树听有曲折经历的人的演讲时一件很欢喜的事。
一席话,几十年,人生智慧蕴藏其中。
他的经历特别让我有感触,忍不住想和朋友们分享。
他说,小时侯,他的家境特别殷实。
他父亲的朋友也很多,所以,上学的时候尽管学习一般,可是,从小学到中学,在到一所大学,都一帆风顺。
毕业后,他顺利进入一家好的公司,很快升迁,又很快辞职,自己办公司,不到几年公司已有声有色。
不过,有一年,他的父亲突然去世,以后他的霉运接踵而至。
先是销售问题,在是财政问题,在是......真是祸不单行,最终,他只能和母亲回到乡下苟且度日。
一天,他发现一个奇怪的现象:许多乡亲把一些大树下的小树都刨去了。
他很是不解,这时,一个人说:“这你就不懂了吧,我们只是想给它换个环境罢了。
小树在很小的时候,在大树的庇护下顺利而安全的成长,可是,在它长到一定大的时候,大树的保护就影响它的快速成长,让它变得很脆弱。
同时,小树在这个时候需要更多的阳光和水分,而大树阻挡了小树接受阳光,也把本属于小树的营养不自觉地吸收了。
”于是,恍然间,他明白了一件事————如果想做一株草,那就安心地呆在大树的庇护下吧;如果想做一颗大树,长到一定的时候,就必须吸收更多的营养,接受更多的阳光,而阳光和营养就在风雨的搏击中。
后来,他重入商海,波峰波谷,起起伏伏,跌打滚爬,终于成就一番事业。
这段经历充满传奇色彩,也传递着乡村朴素而古老的人生智慧,站在大树下的小树永远长不大。
若想成为一颗大树,你必须擎起一片天空。
19.许多乡亲把一些大树下的小树都刨去了的原因是什么你认为他们这样做有道理吗为什么(5分)20.怎样理解“如果想做一颗大树,长到一定的时候,就必须吸收更多的营养,接受更多的阳光,而阳光和营养就在风雨的搏击中。
”这句话的含义(6分)21.第一段写了“他”家境的殷实、“他”父亲的朋友很多以及“他”的学业和工作一帆风顺,这样写的目的是什么(4分)22.读完这篇文章,你得到了什么启示请结合实际谈谈你的感想。
(6分)一.选择题(21分)二.非选择题(16分)8.(11分)(1)《________________》,________________,(2)________________,《________________》(3)________________,________________,(4)________________,________________,________________,(5)________________,________________9.(5分)三.阅读(63分)10.(8分)___________,___________,___________,___________11.(4分)___________16.(6分)18.(6分)19.(5分)21.(4分)22.(6分)答案1.C9.要做到观点明确,能自圆其说。
如:我支持正方,探险时一项很具挑战性的活动,富有刺激性,它使人活得有意义,更能证明生命的价值。
