课时规范训练 [单独成册] 1．有关下图所示原电池的叙述不正确的是() A．电子沿导线由Cu片流向Ag片 B．正极的电极反应是Ag＋＋e－===Ag C．Cu片上发生氧化反应,Ag片上发生还原反应 D．反应时盐桥中的阳离子移向Cu(NO3)2溶液 解析：选D。该装置是原电池装置,实质上发生的是Cu与硝酸银的反应,所以Cu失去电子,发生氧化反应,则Cu是负极,Ag是正极,电子从负极流向正极,A 正确；正极是Ag＋发生还原反应,得到电子生成Ag,B正确；根据以上分析,Cu 片上发生氧化反应,Ag片上发生还原反应,C正确；原电池中,阳离子向正极移动,所以盐桥中的阳离子移向AgNO3溶液,D错误。 2．某学习小组的同学查阅相关资料知氧化性：Cr2O2－7＞Fe3＋,设计了盐桥式的原电池,如图,盐桥中装有琼脂与饱和K2SO4溶液。下列叙述中正确的是() A．甲烧杯的溶液中发生还原反应 B．乙烧杯中发生的电极反应为2Cr3＋＋7H2O－6e－===Cr2O2－7＋14H＋ C．外电路的电流方向是从b到a D．电池工作时,盐桥中的SO2－4移向乙烧杯 解析：选C。因为氧化性：Cr2O2－7＞Fe3＋,所以该原电池反应是Cr2O2－7将Fe2
＋氧化为Fe3＋,所以甲烧杯发生氧化反应,A错误；乙烧杯发生还原反应,电极反应为Cr2O2－7＋6e－＋14H＋===2Cr3＋＋7H2O,B错误；根据以上分析,a是负极,b是正极,则电流方向是从正极向负极流动,C正确；原电池中的阴离子向负极移动,所以SO2－4向甲烧杯移动,D错误。 3．将编号为①②③④四种金属片两两相连浸入稀硫酸中都可组成原电池。 ①②相连时,外电路电流从②流向①；①③相连时,③为正极；②④相连时,②上有气泡逸出；③④相连时,③的质量减少。据此判断这四种金属活动性由强到弱的顺序是() A．①③②④B．①③④② C．③④②①D．③①②④ 解析：选B。①②相连时,外电路电流从②流向①,说明②为正极,①比②活泼；①③相连时,③为正极,说明①比③活泼；②④相连时,②上有气泡逸出,说明②是正极,④比②活泼；③④相连时,③的质量减少,说明③是负极,③比④活泼,故金属活动性由强到弱的顺序是①③④②。 4．利用如图所示原电池可测量空气中Cl2含量,其中电解质是Ag＋可以自由移动的固体物质。下列分析不正确的是() A．电子经外电路流向Pt电极 B．电池工作时,电解质中Ag＋数目减少 C．正极反应：Cl2＋2e－＋2Ag＋===2AgCl D．空气中c(Cl2)越大,Ag极消耗速率越快 解析：选B。Ag的金属活动性强于Pt,则Ag电极是负极,Ag失去电子,则电子经外电路流向Pt电极,A正确；正极是Cl2得到电子,与Ag＋结合生成AgCl,即

I had one trip last year where I was caught by a hurricane in America.I picked up the stem cells in Providence，Rhode Island，and was meant to fly to Washington then back to London.But when I arrived at the check-in desk at Providence，the lady on the desk said：“Well，I'm really sorry，I've got some bad news for you—there are no flights from Washington.” So I took my box and put it on the desk and I said：“In this box are some stem cells that are urgently needed for a patient—please，please，you've got to get me back to the United Kingdom.”She just dropped everything.She arranged for a flight on a small plane to be held for me，re-routed(改道) me through Newark and got me back to the UK even earlier than originally scheduled. For this courier job, you're consciously aware that in that box you've got something that is potentially going to save somebody's life. 1．Which of the following can replace the underlined word “courier” in Paragraph 1? A．provider B．delivery man C．collector D．medical doctor 2．Why does Peter have to complete his trip within 42 hours? A．He cannot stay away from his job too long. B．The donor can only wait for that long. C．The operation needs that much time. D．The ice won't last any longer. 3．Which flight did the woman put Peter on first? A．To London. B．To Newark. C．To Providence. D．To Washington. 课时达标训练《陈情表》 (时间：40分钟 分值：50分) 一、基础巩固(15分，选择题每小题2分) 1.[对应链接高考]下列选项中不含通假字的一项是( ) A ．夙遭闵凶 B ．缙绅、大夫、士萃于左丞相府 C ．共其乏困 D ．辞不赴命 2．下列各组句子中加点词的意义和用法不相同的一项是( ) A.????? 生孩六月，慈父见．背私见．张良 B.????? 州司临门，急于．星火冰，水为之而寒于．水 C.????? 外无期功强近之．亲维扬帅下逐客之．令 D.????? 欲苟顺私情，则．告诉不许于其身也，则．耻师焉 3．下列各句中加点词的古今意义相同的一项是( ) A ．零丁孤苦，至于成立．． B ．岂敢盘桓，有所希冀．． C ．是以区区．． 不能废远 D ．欲苟顺私情，则告诉．． 不许 4．下列句中加点词的活用现象，与其他三项不同的一项是( ) A ．历职． 郎署 B ．但以刘日． 薄西山 C ．非臣陨首所能上． 报 D ．臣不胜犬马．． 怖惧之情 5．下列句子的句式特点与其他三项不同的一项是( ) A ．州司临门，急于星火 B ．计未定，求人可使报秦者 C ．蚓无爪牙之利，筋骨之强 D．缙绅而能不易其志者 6．名篇名句默写。(每空0.5分，共5分) (1)______________，内无应门五尺之僮；____________，形影相吊。 (2)郡县逼迫，催臣上道；____________，____________。 (3)____________，凡在故老，犹蒙矜育，____________，特为尤甚。 (4)但以刘日薄西山，__________________，人命危浅，________________。 (5)__________，死当结草。__________，谨拜表以闻。 二、阅读鉴赏(19分，选择题每小题3分) 阅读下面的文言文，完成7～10题。 李密，字令伯，犍为武阳人也，一名虔。父早亡，母何氏醮①。密时年数岁，感恋弥至，烝烝②之性，遂以成疾。祖母刘氏，躬自抚养，密奉事以孝谨闻。刘氏有疾，则涕泣侧息，未尝解衣，饮膳汤药必先尝后进。 人教A高中数学选修2-3同步训练 1．计算C28＋C38＋C29等于( ) A．120 B．240 C．60 D．480 解析：选A.原式＝C39＋C29＝C310＝120. 2．若C7n＋1－C7n＝C8n，则n等于( ) A．12 B．13 C．14 D．15 解析：选C.C7n＋1－C7n＝C8n，即C7n＋1＝C8n＋C7n＝C8n＋1，所以n＋1＝7＋8，即n＝14. 3．某校一年级有5个班，二年级有8个班，三年级有3个班，分年级举行班与班之间的篮球单循环赛，总共需进行比赛的场数是( ) A．C25＋C28＋C23B．C25C28C23 C．A25＋A28＋A23D．C216 解析：选A.分三类：一年级比赛的场数是C25，二年级比赛的场数是C28，三年级比实用文档 赛的场数是C23，再由分类加法计数原理可求． 4．把8名同学分成两组，一组5人学习电脑，一组3人做生物实验，则不同的安排方法有________种． 解析：C38＝56. 答案：56 一、选择题 1．下面几个问题中属于组合问题的是( ) ①由1,2,3,4构成的双元素集合；②5个队进行单循环足球比赛的分组情况；③由1,2,3构成两位数的方法；④由1,2,3组成无重复数字的两位数的方法．A．①③B．②④ C．①②D．①②④ 答案：C 2．已知平面内A、B、C、D这4个点中任何3点均不共线，则由其中任意3个点为顶点的所有三角形的个数为( ) A．3 B．4 实用文档 实用文档 C ．12 D ．24 解析：选B.C 34＝4. 3．C 03＋C 14＋C 25＋C 36＋…＋C 1720的值为( ) A ．C 321 B ． C 320 C ．C 420 D ．C 421 解析：选D.原式＝() C 04＋C 14＋C 25＋C 36＋…＋C 1720 ＝() C 15＋C 25＋C 36＋…＋C 1720 ＝(C 26＋C 36)＋…＋C 1720＝C 1721＝C 21－1721＝C 421 . 4．若A 3n ＝12C 2n ，则n 等于( ) A ．8 B ．5或6 C ．3或4 D ．4 解析：选A.A 3n ＝n (n －1)(n －2)，C 2n ＝12n (n －1)， ∴n (n －1)(n －2)＝6n (n －1)， 又n ∈N *，且n ≥3.解得n ＝8. 5．从6位同学中选出4位参加一个座谈会，要求张、王两人中至多有一个人参加，课时规范训练(37)
