在事实上,宇宙是否有暗物质与暗能量的存在,其时空隧道又是什么?

In fact,she can't swim

答案C
悄无声息体现了文化对人的影响具有潜移默化的特点,故选C.

首先解释下,过氧化钠中的氧是一个原子团,叫做过氧根离子.
两个氧原子以一个共价键结合,所以每个氧原子还有一个孤对电子,整个过氧根离子显-2价
所以每一个氧原子是显-1价

助词“等”常用于书面语,放在两个或两个以上并列的词或短语之后,其作用有二：
1.表示列举未完.运用情况是：被省略的部分或因不重要或不必要而不一一列出,或因知道得不确切而无法说出.例如：
①房间里有一张单人床,右边是书桌、书架等简单的陈设.
②唐代著名诗人李白、杜甫、白居易、王维、孟浩然等.
③工具箱里放着鎯头、锯子、凿子、锉刀、螺丝刀等东西.
例①,房间右边显眼的如书桌、书架都说出来了,其他不重要的就用“等”字带过.例②,唐代的著名诗人很多,举出最著名的几位就可以了,没有必要一一列出.例③,工具箱里放的东西很多,没法一一说全.
2.表示列举后煞尾.这种用法的“等”,后面经常带有前列各项总计的确切数字.例如：
④我国有长江、黄河、黑龙江、珠江等四大河流.
⑤六年来我们学习了语文、数学、思想品德、历史、地理、自然常识、音乐、美术、体育等九门课程.
例④⑤中的“等”字后都带有前列各项总计的确切数字,这种用法的“等”字可以去掉而不影响原意的表达.而例①②③中的“等”字是不可去掉的,去掉后句子就不通,或意思就不完整.

Yes,I do.不,我经常穿
No,I don't.是的,我不穿

解题思路：根据题意知：可设买的苹果每斤X元，买了Y斤．则XY=40，（X+5）×（Y-0.4）=40，据此可列方程组解答．

设买的苹果每斤X元，买了Y斤，根据题意得


XY＝40
(X+5)(Y−0.4)＝40


XY＝40
5X−0.4Y＝2
解

X＝2
Y＝20．
答：水果店老板所买的苹果是2元一斤，买了20斤．
故答案为：2，20．

从牛顿所创立的体系来讲,这三条定律是相互独立的.随着数学工具的日臻完善,后人将牛顿力学发展到了分析力学（属于理论力学部分）,所有的定理都可以从哈密顿原理推导出来.

从只会在襁褓中哇哇啼哭,到我们喃喃学语叫出第一声爸妈,到第一次踩着小脚丫跌跌撞撞地走路.第一次背着书包走向学校,第一次拿回考试成绩,第一次离开父母……也许你从没注意到在这无数次的第一次中,在这漫长的成长道路上父母付出了多少心血倾注了多少爱.你的每一次微笑,每一次成功,甚至是每一次失败,每一次犯错误父母都会牢牢记在心头,陪在你身边,给予你默默的支持……
我们从哪里来?听到这个问题,大家肯定都会说,是父母把我们带到世界上来的.是啊,十三年前的一天,我们的父母用泪水和幸福的笑容迎接了我们的到来.从我们来到世上的那一刻起,父母们又多了一项繁重的工作——照顾我们.尽管这是一种沉重的负担,但从婴儿的“哇哇”坠地到哺育我们长大成人,父母们花去了多少的心血与汗水,编织了多少个日日夜夜,父母们却毫无怨言.
小的时候,我总把父母对自己的爱当作天经地义,因为我不了解,也不知道父母的辛苦.现在,我长大了,我知道该怀着一颗感恩之心去体谅父母,应该担当起,照顾、孝敬父母的责任.
可是又有多少人是把父母放在第一位的呢?有的人总是不断地报怨自己的父母这样不好,那样不对,对父母的行为和做法挑三拣四,横加指责,甚至于直接与父母顶撞!有些人不知道自己父母身体的健康状况,不记得自己父母的生日,有的连自己父母的工作单位在哪都不知道,想想看,父母为我们付出那么多精力和心血啊!
当我们遇到困难,能倾注所有一切来帮助我们的人,是父母.
当我们受到委屈,能耐心听我们哭诉的人,是父母.
当我们犯错误时,能毫不犹豫地原谅我们的人,是父母.
当我们取得成功,会衷心为我们庆祝,与我们分享喜悦的,是父母.
而现在我们远在外地学习,依然牵挂着我们还是父母.
生活并非想象中那样完美,父母的辛勤是我们无法体会的,我们虽不能与父母分担生活的艰辛、创业的艰难,但我们在生活上可以少让父母为自己操心.当父母生病时,我们是否应担起责任,照顾父母?要知道,哪怕一句关心的话语,哪怕一碗自己泡好的方便面,都会慰藉父母曾为我们百般焦虑的心.
感恩的心的生活是美好的,生命犹如一张白纸,有了感恩的心,这纸上便会出现粉红.一生都怀抱感恩,纸的底色也便是粉红,也就有了美好的人生.
假如今天是我生命中的最后一天,我们要做的第一件事情,就是报答养我育我的父母!“滴水之恩,当涌泉相报.”更何况父母为我们付出的不仅仅是“一滴水”,而是一片汪洋大海.
感恩,它虽说是一个行为动词,但它不止需要行动,更重要的是需要做到真心实意.简单地说,感恩便是感激,发自内心的感激.
（还有一个）世界上有许多让我感谢的人们,我感谢无私奉献、像园丁一样培育着我们这些祖国花朵的老师,我感谢有困难时,帮助我的同学.而我最要感谢的是那不辞辛劳,那颗炽热的心总是向着我的爸爸、妈妈!
父母,是给予我们生命的伟大神灵,是教育我们人生第一步的启蒙老师,是培育我们茁壮成长的辛勤园丁,是提醒
我们堂堂正正做人的红色警钟……
母亲给与我们生命,是我们的生命之源.“母爱”是天下最伟大的“爱”.从我们还没有出生的时候,母亲就开始照顾我们、看护我们、爱护我们、给与我们无微不至的关怀了.只要我们健康、开心,母亲就会比我们更开心.母亲是教导我们如何做人的第一个启蒙老师,她教会我们如何做人,如何做好人,如何在社会生存.所以我们都是受母亲的直接影响,才会有开心的今天、安逸的今天.
父亲给与我们做人的道理、生存的技巧,教会我们要坚强、要率真、要有毅力.所以我们今天的坚强、毅力、生存之道都有父亲的影响.
让我们以感恩的心来回报我们亲爱的父母.
我的父亲母亲!

你看的什么书,除了ZnCl2离子键为主,其它都是共价化合物
氯化锌是一种离子化合物,有同质多晶现象,目前已发现四种晶体结构.但纯氯化锌只能形成δ型（六方密堆积）,即在晶体中,每个锌离子被4个氯离子成正四面体状包围.[1]将它熔融后再冷却可以得到玻璃状的物质.
氯化锌还显示出共价化合物的特性,如熔点低(275 °C)、易溶于乙醚等溶剂形成形如ZnCl2L2（其中L代表溶剂分子）的加合物.

您好,查了不少资料,关于原文,很多是英文的原始资料.翻译如下,希望对您有帮助：
The Cartesian Doubt is the principle of Descartes' methodology. As a matter of fact, the Cartesian Doubt is also the process of being skeptical about methodology itself, which is for the purpose of acquiring indubitable truth and genuine knowledge. He believes that among the knowledge we acquired previously, some is genuine, but some is false. Thus Descartes starts to doubt all things, in order to acquire a firm foundation for genuine knowledge. He always doubts, till he doubts his own existence. However, he thought that "if I do not exist, then how come I am thinking right here?" Therefore, the famous philosophical statement "I think, therefore I am" ("Cogito ergo sum") was concluded.

解题思路：（1）要掌握各种物质的颜色；
（2）活性炭具有吸附作用，能够吸附色素和异味；
（3）物质的结构决定物质的性质．

（1）氢氧化铁是红褐色的物质，胆矾是蓝色物质．故填：氢氧化铁；胆矾．
（2）活性炭具有吸附性，可用作冰箱除臭．故填：活性炭．
（3）SO₂、C、Fe₃O₄、CuO中，二氧化硫是无色气体，碳、四氧化三铁、氧化铜等物质都是黑色固体．故填：SO₂；因为只有它是气体或没有颜色．

点评：
本题考点： 碳单质的物理性质及用途；物质的简单分类；化学性质与物理性质的差别及应用．

考点点评： 本题主要考查物质的性质和用途，物质具有多种性质，解答时应该理解物质的用途是由物质的哪种性质决定的．

苏轼说过一句话：“大勇若怯,大智若愚”.所以你要用实力来维护谦虚,一知半解的人,多不谦虚；见多识广有本领的人,一定谦虚.在那些既骄傲又爱显摆的人面前谦虚更显得弥足珍贵,谦虚的过程也是不断自我超越的过程,人生会变得更加充实,自身价值会不断得到提升,你何乐而不为呢?也许你内心是好的,但你的傲气让同学误解了,在他们眼里你太清高,最好的办法就是跟他们多接触,他们对你的误解就会不攻自破了~
