句子练习范文4

句子的衔接,实际上是语言表达上连贯的要求,它要求一个语段的各个句子之间,或是一个复句的各个分句之间,在内容和形式上都能接得上、扣得紧,使全文脉络清晰,文气顺畅,准确而又完整。句子的衔接,能综合检测出学生语言运用中的各项能力。因此颇受命题者青睐。句子衔接试题的主要题型依然是选择题和填写题。在一段文字中为上下文衔接选填恰当的句子;用序号重新排列句子顺序,使其通顺并前后衔接一致;在一段文字的空白处插入与上下文相衔接的句子;在语段中选填句子顺序正确的选项;在一段文字的末尾填写与前文相一致的句子。因此,考生在解答句子排序试题时,要注意语段中句与句之间的关系,尤其是句子前后之间的衔接。

・【方法指津】

句子衔接题由两部分组成,即题干项和衔接项。不管何种类型的衔接题,首要的也是必须的即分析理解题干项,把握题干项与衔接项之间的关系,是解答此类题的突破口。实际上,题干项就是衔接题的“语境”(即上下文)。阅读能力较强的学生,凭其较好的“语感”(即对语言的一种特殊感知能力),也是可以轻松作答的。但是,任何事物都有其技巧,衔接题亦如此。若思路对,则可以迎刃而解;若思路不对,则事倍而功半,甚至无功而返。

・【真题解析】

一、语意是否相连。语意的连贯,是指上下文在语意上关系密切,相互呼应。针对这些特点,我们可以在把握句子整体意义的基础上,把握关键词、关键句来解答衔接题,如话题的统一、观点与材料的关系等

例1.(2011年四川省眉山市)下面这段文字的恰当顺序是( )

①从古代史到现代技术,从数学到插花,不精通各种知识就一事无成。②这种情况可能出现在六分钟之后,也可能在六个月之后,六年之后。③因为这些知识随时都可能进行组合,形成新的创意。④但当事人坚信它一定会出现。⑤富有创造性的人总是孜孜不倦地汲取知识,使自己学识渊博。

A. ⑤①③②④ B. ①③②④⑤ C. ⑤③①②④ D.①③⑤②④

【解析】本题重点考查考生语言表达连贯的能力。通读全句看第⑤句是总论,①承接⑤从反面举例论证,③承接⑤①说原因,②承接③论述,④承接②论述。

【参考答案】A

二.事理是否相承。句子衔接首先是意思表达要符合客观事理,合乎思维规律,即合乎逻辑,否则上下句在事理上就会出现“裂痕”,衔接不上。分句间的逻辑关系常有:转折、因果、条件、递进、并列、总分、大小、轻重、快慢、多寡等。

例2. (2011年浙江省余姚市)用上恰当的关联词语,将下面三个短句组合成一个复句(句序合理,语意贯通,标点正确,可以删去和调换词语,但不得改变原意)。

①你的朋友是积极向上的人,你就可能成为积极向上的人。

②能从中得到激励,从而获得人生的快乐与幸福。

③与消沉的人厮混,你不可能进取。

【解析】 本题主要考查考生语言表达连贯的能力。解答这类题目可先纵观整个语段,基本确定前后句的关系,纵观这三句我们可以用表假设的关联词去连接结果就会出现可喜的效果。

【参考答案】 如果(假设)与消沉的人厮混,你不可能进取;如果(假设)你的朋友是积极向上的人,你就可能成为积极向上的人,并且能从中得到激励,从而获得人生的快乐于幸福。

三、结构是否相应。语句间的相应,包括答句与问句间的照应、上下句词语间的照应、前后句式间的照应等。

在设问句中,前句提出问题,后句便要求作出正确的回答。有的问句一连提出两个问题,便要同时兼顾两个问题,作出正确的回答。如果答非所问或者一概否定、一概肯定,都会造成语句的不连贯。

例3(2011年重庆市潼南县).下列句子按语意排列最恰当的一项是( )

①如果宇宙没有生命,怎么会从中开出灿烂的生命之花?

②宇宙是一个硕大无比的、永恒的生命,那永恒的运动、那演化的过程,不正是她生命力的体现吗?

③谁说宇宙是没有生命的?

④这个宇宙到处都隐藏着生命,到处都有生命的萌芽,到处都有沉默的声音。

⑤你难道没有用心灵听到从那遥远的星系里传来的友好问候?

⑥你难道没有听到石头里也有生命的呐喊?

A.②③①④⑥⑤ B.③②①④⑥⑤ C.③②①⑤④⑥ D.②③④⑥⑤①

【解析】 题主要考查考生语言表达连贯的能力。纵观全局根据语意本语段有三组设问句,③句中运用设问提出了宇宙是有生命的?紧承②来回答宇宙是有生命的;第①也是运用设问句提出问题,第④句回答;第⑥句也是提出问题,第⑤回答的。了解了这个特点,本题排列较为简单。

【参考答案】 B

四、主语是否相同。句子的主语协调一致,是保持语句连贯的重要技巧。作为陈述对象的主语若一致,则语段的陈述话题、说明中心、议论角度也就相应一致了。

例4. (2011年云南省德宏州)下列句子排序最恰当的一项是( )

①此时,夜幕已经完全降临,黑沉沉的夜空,星光稀缀。

②时而有游船从身边掠过。

③湖面上,灯影、船影交辉,桨声、水声和弦,如同无数条金蛇狂舞,闪烁着粼粼波光,就像一个天然的舞台。

④也有的只是一对情侣依偎在船舱之中或是船头轻轻细语。

⑤船上,有的琴音笙歌不绝于耳。

A.①③⑤②④ B.①③②⑤④ C.①②③⑤④

D.①⑤④③②

【解析】 本题这几个语句应该按空间顺序排列即为:夜幕降临后的星空―湖面美景―游船―船上美景。所说的是夜幕下的“美景”,按照有上到下的时间顺序排列的。运用排除法进行解答,本题符合这个要求是即为B。

【参考答案】B

五、语境是否相符。对于写景复句或语段,要注意语境因素,分析景物、情调、写法的特点。景物,有远近、动静的不同;色彩,有鲜明、暗淡的区别;气氛,有热烈、冷清之分;视角,有高低、俯仰之异。如果不注意这些差别,就不容易辨别选项的正误。

例5. (2011年湖南省郴州市)给下列句子排列顺序。(写序号)

①这样看来,花香鸟语,草长莺飞,都是大自然的语言。

②杏花开了,就好像大自然在传语要赶快耕地;桃花开了,又好像在暗示要赶快种谷子。

③几千年来,劳动人民注意了草木荣枯,候鸟去来等自然现象同气侯的关系,据以安排农事。

④布谷鸟开始唱歌,劳动人民懂得它在唱什么:“阿公阿婆,割麦插禾。”

【解析】 本段节选的是《大自然的语言》中的语段,内容是在介绍什么是大自然的语言。所给的死个句子都是围绕这个语境经行介绍的,我们只要找到第一句和最后一句,就能解答好这道题目,按照有总说到分说进行排列,第一句是③句,其次是②④①句。

【参考答案】③②④①

・【能力提升】

1. 下列依次在①②③处填入的词语和句子,语意和衔接都最恰当的一项是( )

听证会虽然是一种较为 ① 的公众参与形式,但是其运行成本较高、效率较低的特点也决定其并不②大范围广泛采用,相反,③ 。政府可以自行也可以通过社会调查公司、网络公司对公众的意见和建议进行了解,并提供政府参考,关键是这种参与的过程也应公开进行。

据国外媒体报道,在3月22日召开的诺西投资者大会上,西门子CFO乔・凯瑟尔(Joe Kaeser)表示,西门子无意继续保留诺西股份,他说:“我认为,西门子应该在2013年帮助诺西进入到一个更好的状态。”由于诺西两大股东诺基亚与西门子的合作协议将于今年4月1日到期,凯瑟尔的表态加剧了市场对该公司未来命运的猜测。

就在凯瑟尔表示将放弃诺西股份前一天,诺西通信宣布将发售6亿欧元(约合7.79亿美元)债券,并计划用这笔债券收入来偿还贷款及债务。这也是该公司首次在资本市场进行融资。对此,一些业内分析人士表示,诺西此举或许是为即将到来的公司股权变更做准备。

今年2月,欧洲市场上便有消息传出,称德国人已经就退出问题与芬兰人展开了谈判。该人士表示,根据双方正在讨论的一项方案,后者将与另一位战略合作伙伴共同收购前者所持有的全部诺西股份,这位“战略合作伙伴”很可能是阿尔卡特朗讯(阿尔卡特和朗讯成立的合资公司,以下简称“阿朗”)。

诺西的成立曾一度被业内视为西门子和诺基亚的强强联合,但自成立起,这家公司就亏损不断,2012年的净亏损额高达14.6亿欧元(约合18.9亿美元)。据行业分析师拉尔斯・索德尔吉尔(Lars Soederfjell)估计,目前诺西的市值约为100亿欧元(约合136亿美元)。

有来自欧洲市场的分析指出,全球电信设备市场的萎缩,以及来自华为、中兴等中国对手的竞争,让本就处于亏损中的诺西更加举步维艰。

目前,市值410亿美元的爱立信仍是全球最大的电信设备供应商,但华为与它的差距正在不断缩小。尽管被挡在美国大门之外,华为未经审计的营收依然达到350亿美元,几乎与爱立信持平,其强劲的增长势头让不少业内人士认为它极有可能在年内超过爱立信。不过,由于去年电信设备市场的不景气,除了华为,爱立信、中兴等企业的业绩都出现不同程度的下滑。爱立信去年第四季度出现10亿美元的亏损,近年来一直极力推行海外扩张策略的中兴的亏损更为严重,其市值已缩水至146亿美元。

不久前,诺西CEO苏里(Rajeev Suri)表示,由于全球电信市场增速放缓,未来市场将只有三家电信设备供应商能够维持盈利,他希望“诺西成为其中之一”,但以如今的市场环境和诺西的现状来看,苏里的希望很难实现。

尴尬的“强强联合”

2006年,当时的诺基亚稳坐全球手机行业头把交椅,德国老牌电气公司西门子则拥有从照明到铁路的广泛业务。为了开拓全球电信设备市场,两家公司于当年6月宣布将双方的通信业务合并,各出资50%成立诺基亚西门子通信公司,交易总额高达250亿欧元,并于次年4月正式投入运营。

当时诺基亚和西门子预计,诺西的成立将会增加双方的营收,并有望成为全球最大的电信设备制造商。然而事与愿违,诺西并未实现盈利,反而从一开始就陷入了持续亏损,到2009年,诺西的年运营亏损已经达到16亿欧元。

由于对诺西的业绩感到不满,西门子在2010年便已萌生退意。只是一直未能找到合适的接收人,而在此期间,诺西的市场表现不但没有起色,反而在2010年被中国的华为公司超越,丢掉了第二的位置。

近两年,随着全球电信行业的增长放缓,运营商纷纷削减设备采购开支,因而制造商之间的竞争也变得愈发激烈。在移动网络上,诺西无力追赶爱立信,又不断受到华为的冲击;固网方面则基本上是阿朗和中兴平分天下,诺西不占优势。

为了扭转长期亏损的局面,诺西不得不从去年开始全球战略重组,将移动宽带和服务作为未来的战略重点。为了节省运营费用,诺西于2013年底前裁减约1.7万名员工,占到其员工总数的四分之一。此外,诺西还出售了手中的BSS、光纤网络等众多业务。

通过裁员和对非核心业务的剥离,诺西终于在去年第三季度首次实现9.2%的盈利,但其全年业绩依然亏损严重。诺西的重组计划似乎收到了成效,但有业内分析人士认为,电信行业投资周期较长,诺西一旦放弃部分产品线以及规模化经营方式,当其自身的资源难以支撑其发展时,会容易出现布局失误,这可能会将其带入新的困境,尤其在目前电信设备市场收缩的情况下。

当初期待的“强强联合”陷入如此尴尬的境地,加上在手机市场节节败退的诺基亚几乎自身难保,西门子对诺西的未来更加失去信心。如同当年放弃移动电话部门那样,对于正在计划朝新能源等创新领域转型的西门子来说,尽早甩掉诺西这个包袱无疑是正确的决定。

何去何从

一旦西门子宣布退出,诺西必将迎来一场巨变,有分析认为,一个最为顺理成章的结果是:诺基亚收购西门子手中的诺西股份,这样诺西将会成为诺基亚的全资子公司。

不过丹麦银行分析师罗伯特・雅各布森明确指出这种情况不可能发生,“很难说诺西命运将会如何,但最后肯定不会由诺基亚独自拥有”。

雅各布森的说法并非没有道理。根据诺基亚刚刚的第四季度财报,其营收已连续第7个季度保持下滑。对于芬兰公司来说,目前最重要的是提高现金储备,况且这家公司的战略重心依然是智能手机业务,它显然不愿也无力购买更多诺西的股份。

而根据一些知情人士透露的消息,最有可能的结果便是诺基亚联合另一家公司共同收购西门子的股份。正如前文所述,准备介入的这家公司可能是阿朗。

与诺西一样,阿朗此刻也面临着需求下降和亏损问题,不得不实施总额12.5亿欧元的成本削减计划。而自阿尔卡特和朗讯合作至今,该公司市值已下滑约70%,总计亏损达到100亿欧元。此外,阿朗CEO本・韦华恩(Ben Verwaayen)已确定将于今年5月离职,该公司内部也将迎来大幅人动。

中图分类号:TP311 文献标识码:A 文章编号:1009-3044(2016)08-0010-01

ADO是ActiveX Data Objects的缩写,它是一个组件库,包含了一系列的函数,可以使用微软编程技术来访问数据库的数据。由于微软公司一直在推广技术,所以就有了技术,它能够在微软的NET编程环境中更好的使用数据访问接口,下面我们就来介绍常用的数据库访问所需使用的连接字符串,在下面所有介绍的连接字符串中所用到的数据库参数作在此做统一说明,Server服务器名称MyServer,Data Source数据源使用MyBookDb,User Id用户Id使用MyId,Password使用MyPasswd,为了访问数据库的安全,下面所有的连接都使用密码验证来访问。

1 常用的几种数据库连接符串

1.1 连接Oracle所使用的连接字符串

需要在.NET Framework引入OracleConnection 类库以及所在的命名空间System.Data.OracleClient,然后通过"Data Source=MyBookDb; User Id=MyId; Password=MyPasswd; Integrated Security=no; "这个连接字符串即可使用来访问ORACLE数据库了。其中Integrated Security=no表示没有集成Windows的验证方式,在连接的过程中必须要使用正确的用户名和密码才能访问数据库。

1.2 连接SQL Server所使用的连接字符串

需要在.NET Framework引入SqlConnection类库以及所在的命名空间System.Data.SqlClient,然后通过"Server=MyServer; Database=MyBookDb; User ID=MyId; Password=MyPasswd; Trusted_Connection=False" ,连接字符串来进行访问,其中Trusted_Connection=False也是需要通过使用正确的用户名和密码才能访问数据库。

1.3 连接ACCESS所使用的连接字符串

需要在.NET Framework引入OleDbConnection类库以及所在的命名空间System.Data.OleDb,然后通过"Provider=Microsoft.Jet.OLEDB.4.0; Data Source=MyBookDb.mdb; Jet OLEDB:Database Password=MyPasswd; "字符串,使用中的对象即可访问ACCESS数据库。

1.4 连接Sybase所使用的连接字符串

需要在.NET Framework引入AseConnection类库以及所在的命名空间Sybase.Data.Aseclient?,它的连接字符串为"Data Source='MyServer'; Port=5000; Database='MyBookDb'; UID='MyId'; PWD='MyPasswd'; "在Sybase连接字符串中增加了Port=5000,表示的是数据库的端口号。连接成功后就可以正常访问数据库了。

1.5 连接MySQL所使用的连接字符串

对于MySQL数据库?,我们可以使用一个第三方的工具dotConnect for MySQL所提供的功能来访问数据,它的连接字符串为User ID=MyId;Password=MyPasswd;Host=localhost;Port=3306;Database=MyBookDb;Direct=true;Protocol=TCP;Compress=false;Pooling=true;Min Pool Size=0;

Max Pool Size=100;Connection Lifetime=0;连接成功后可以完全像在使用中的对象一样来访问数据库。

对于其余的数据库,我们都可以使用同样的方式利用ODBC或OLEDB的方式来访问,例如:如果要访问EXCEL数据,可以通过连接字符ODBC的连接字符串"Driver={Microsoft Excel Driver (*.xls)}; DriverId=790; Dbq=C:\MyBookDb.xls; DefaultDir=c:\mypath; "来访问,读写数据库的方式都大同小异。

2 通过连接字符串进行数据库操作

共有五大对象,分别是Connection 对象,用于对数据库进行连接;Command对象,用于对数据库执行命令; DataReader对象,用于从数据库中按顺序读取数据;DataSet对象,用于对数据库执行命令和缓存数据;DataAdapter对象,是数据集和数据库之间联系的桥梁。通过这些对象的使用,即可轻松操作数据库,下面我面来看一下通过操作数据库的基本步骤和方法。这里主要使用C#语言并通过的对象来操作数据库。

通过以上操作,即可方便地访问数据库资源,对数据库的增、删、查、改同上面的操作过程类似,没有特别之处。在程序设计过程中,通常将前面的功能封装到一个函数中,需要的时候直接调用函数即可。

4 结束语

我们介绍了在中几种常用的数据库连接字符串的方法,并写出了一个操作数据库的具体执行步骤,当掌握了以上方法后,编程人员就可以轻松操作各种数据库。
