【英语】高中英语语法填空试题(有答案和解析)及解析 一、高中英语语法填空 1.阅读下面短文,在空白处填入1个适当的单词或括号内单词的正确形式。 Since 1949 when the People's Republic of China ________(establish), and especially since 1978, China's transformation from a traditional ________(agriculture)society to a modern industrial society has been greatly accelarated by a rapid industrial restructuring. China's industrial structure developed according to the objective of industrialization, ________ aimed at the proportion(比例)of agriculture declining ceaselessly, and the proportion of the industrial and service sector increasing continually. ________(current), the industrial goods produced in China all range from capital goods to consumption goods. China's factory outputs extend from textiles (纺织业) to railway, planes and computers. China is the largest producer of inexpensive cotton textiles in the world and exports large ________(quantity) of textiles and clothes. Food processing is very important, and much farm produce is exported. Other industrial products ________(include)television sets, bicycles, cars, trucks and washing machines are expanding in the world. China has become ________ industrialized country to some extent. The auto and the housing industry, in the process of industrialization have developed by leaps and bounds. The most important export products are machinery and electric equipment,________ the most important import products are raw materials. In recent years, China's industry________(compete) internationally, and as a result, the ________(develop)of the country's industry is increasingly influenced by international economic environments. 【答案】was established;agricultural;which;Currently;quantities;including;an;while/and;has competed has been competing;development 【解析】【分析】本文是一篇说明文,自1978年以来,中国从传统农业社会向现代工业社会的转型,在产业结构调整的快速推进下,取得了长足的进步。中国在一定程度上已经成为一个发达的工业化国家。 (1)考查时态语态。根据Since 1949可知应用一般过去时,且主语the People's Republic of China与谓语动词establish构成被动语态,用一般过去时的被动语态,故填was established。 (2)考查形容词。society为名词,需要形容词修饰,故填agricultural。 (3)考查定语从句。句意:中国的产业结构是按照工业化的目标发展的,其目标是农业比重不断下降。本句为定语从句修饰先行词the objective of industrialization,且先行词在从句中做主语,指物,故用关系代词which,填which 。 (4)考查副词。句意:目前,中国生产的工业产品从资本品到消费品应有尽有。修饰整个句子应用副词,故填Currently。 (5)考查名词。large quantities of固定短语,“大量……”,故填quantities。 (6)考查非谓语动词。句意:包括电视机、自行车、汽车、卡车和洗衣机在内的其他工业产品正在世界范围内扩张。本句已经存在谓语动词且句中没有连词,故include只能做非谓语,表示“包括;包含”后跟包含的内容时需用现在分词,故填including。

电力系统分析作业答案

作业 1、什么叫电力系统、电力网及动力系统?电力系统为什么要采用高压输电? 答:把生产、输送、分配和消费电能的各种电气设备连接在一起而组成的整体成为电力系统。 电力系统加上发电厂的动力部分就称为动力系统。 电力系统中输送和分配电能的部分就称为电力网 当输送的功率和距离一定时,线路的电压越高,线路中的电流就越小,所用导线的截面积可以减小,用于导线的投资也越小,同时线路中的功率损耗。电能损耗也相应减少。 2、为什么要规定额定电压?电力线、发电机、变压器和用电设备的额定电压是如何确定的? 答:为了使电力设备生产实现标准化和系列化,方便运行、维修,各种电力设备都规定额定电压。 电力系统的额定电压和用电设备的额定电压相等。 发电机的额定电压比网络的额定电压高5%。 变压器一次绕组和额定电压与网络额定电压相等,但直接与发电 机连接时,其额定电压等于发电机额定电压。变压器二次绕组的额定

电压定义为空载时的额定电压,满载时二次绕组电压应比网络额定电 压咼10%。 3、我国电网的电压等级有哪些? 答:0 . 22kv 、0 . 38kv 、3kv 、6kv 、10kv 、 3 5kv 、11 v 、 220kv 、 330kv 、 500kv 、7 5 0kv 、10 kv 答::10 . 5kv 、121kv 、 2 4 2 kv kv 、 2 1kv 、 kv 、 .6kv 、38 . 5 kv v 、1 kv v 、4 0 kv 4、标出图 电力系统中各元件的额定电压。 1-7 E1-7

仪器分析习题及答案

1.是否能用普通电位计或伏特计测量参比电极和pH玻璃电极所组成电池的电动势?简述原因。 答:不能。因为玻璃电极的内阻(50MΩ~500MΩ)很高,若采用普通电位计或伏特计测量其电位,会引起较大的测量误差。用普通电位计或伏特计测量玻璃电极所组成电池的电动势时,若检流计的灵敏度为10-9A(测量中有10-9A电流通过),玻璃电极的内阻108Ω,当这微小电流流经电极时,由于电压降所引起的电动势测量误差可达:△E=IV=10-9×108=0.1V,它相当于1.7个pH单位的误差。因此不能用普通电位计或伏特计测量参比电极和pH玻璃电极所组成电池的电动势。 2.已知=0.10,若试样溶液中F-浓度为1.0×10-2mol/L时,允许测定误差为 5%,问溶液允许的最大pH(以浓度代替活度计算)为多少? 解:离子电极选择性误差用下式表示和计算: 即: -离子选择电极插入50.00ml某高氯酸盐待测溶液,与饱和甘汞电极(为3.将一支ClO 4 负极)组成电池。25℃时测得电动势为358.7mV,加入1.00ml NaClO 标准溶液 4 -浓度。 (0.0500mol/L)后,电动势变成346.1mV。求待测溶液中ClO 4 解: -为阴离子,但该离子选择电极为电池的正极,因此S为负值。注意:此题中虽然ClO 4 4. 用离子选择电极校正曲线法进行定量分析有什么优点?需注意什么问题?使用TISAB有何作用? 答:离子选择电极校正曲线法进行定量分析的优点是适用于大批量的样品分析。定量分析中应注意实验条件的一致,特别是待测液和标准溶液系列的离子强度须保持一致。使用TISAB的作用为:①保持待测液和标准溶液系列的总离子强度及活度系数恒定;② 维持溶液在适宜的pH范围内,满足离子电极的要求;③掩蔽干扰离子。

现代汉语语法题库 (带答案)

第四章语法 一、填空题 1、语法这一术语可有三种含义:语法规律、(语法科学)、语法教材。 2、分析语句的结构和功能的目的在于(区别异同、辨明意义)。 3、语法分析有两种基本的方法,一是把大类分成小类,另一是(把整体切为部分)。 4、对现代汉语的词进行语法分类,必须以词的(语法功能)为依据。 5、词的语法功能是指词的(组合能力)。 6、词的分类是逐级进行的,首先根据能否作句法结构成分,可以把词分为(实词)和虚词两大类。 7、根据组合能力的不同可以把实词分为体词、(谓词)、加词三类; 8、现代汉语特殊的词类有两类,一是(叹词),另一是拟声词。 9、量词包括名量词、(动量词)、时量词。 10、不能带宾语的和只能带施事宾语或处所宾语的动词一般叫(不及物动词)。 11、加词包括(副词)和区别词两类。 12、副词的语法特点是一般只能充当(状语)。 13、(代替)功能就是代词的主要语法功能。 14、代词可以分为人称代词、(指示代词)、疑问代词。 15、助词包括结构助词、(动态助词)以及“所、似的”等其他助词。 16、词与词的组合包括实词与实词、实词与虚词的组合,可统称为(短语),也有叫词组的。 17、在句法结构中承担结构关系的关系项叫做句法结构成分,简称(句法成分)。 18、介词不能单独作句子成分,它和词或短语构成介词短语,主要作(动词和形容词或谓词性短语)的修饰语。 19、从语义关系上看,主语可以分为(施事主语)、受事主语、关涉主语。 20、在偏正短语中,起限制或描写作用的成分叫修饰语,修饰语主要指(定语和状语)两种句法成分,被修饰的成分是中心语。 21、句子是能够表达一个相对完整意思的语言单位,每一个句子都有一定的(语调),表示不同的语气。 22、句子的特殊成分有(复说语)和插说语两种。 23、复说语有称代式复说语和(总分式复说语)两种。 24、根据结构关系,单句首先可分为主谓句和(非主谓句)两大句型。 25、非主谓句主要有名词句、(动词句)、形容词句和叹词拟声词句四种。 26、根据主谓句中谓语的性质和特点可以把主谓句分为四种,即名词性谓语句、(动词性谓语句)、形容词谓语句和主谓谓语句。 27、由连动短语充当谓语的句子称连动句,由兼语短语充当谓语的句子是(兼语句)。 28、表示存在、出现、消失的句子一般叫(存现句)。 29、复句一般可以分为(联合复句)和偏正复句两类。 30、因果复句可以分为(说明因果的因果复句)、推论结果的因果复句、说明目的的因果复句三类。 31、假设条件句复句可以分为充分条件句、必要条件句和(无条件句)三类。 32、在复句中用来连接分句并表明分句之间关系的连词、副词和短语,统称(关联词语 )。 33、倒装句是有一定特点的句子,首先倒装的部分可以(复位(或还原)),其次

电力系统分析作业答案

作业一 1、什么叫电力系统、电力网及动力系统?电力系统为什么要采用高压输电? 答:把生产、输送、分配和消费电能的各种电气设备连接在一起而组成的整体成为电力系统。 电力系统加上发电厂的动力部分就称为动力系统。 电力系统中输送和分配电能的部分就称为电力网 当输送的功率和距离一定时,线路的电压越高,线路中的电流就越小,所用导线的截面积可以减小,用于导线的投资也越小,同时线路中的功率损耗。电能损耗也相应减少。 2、为什么要规定额定电压?电力线、发电机、变压器和用电设备的额定电压是如何确定的?答:为了使电力设备生产实现标准化和系列化,方便运行、维修,各种电力设备都规定额定电压。 电力系统的额定电压和用电设备的额定电压相等。 发电机的额定电压比网络的额定电压高5%。 变压器一次绕组和额定电压与网络额定电压相等,但直接与发电机连接时,其额定电压等于发电机额定电压。变压器二次绕组的额定电压定义为空载时的额定电压,满载时二次绕组电压应比网络额定电压高10%。 3、我国电网的电压等级有哪些? 答:0.22kv、0.38kv、3kv、6kv、10kv、35kv、110kv、220kv、330kv、500kv、750kv、1000kv 4、标出图1-7电力系统中各元件的额定电压。 T:10.5kv、121kv、242kv 答: 1 T:220kv、121kv、 2 T:110kv、6.6kv、38.5kv 3 T:35kv、11kv 4 T:10kv、400kv 5 T:110kv、38.5kv 6

现代汉语语法研究—试题精华版(含答案解析)

现代汉语语法研究—精华版 1、语法这—术语有哪几种含义? 答:语法这一术语有三种含义:(1)语法规律,例如:“汉语语法并不难掌握。”这里的“语法”是指客观存在的语法规律。(2)语法科学,例如:“语法研究语言结构的规律。”这里的语法指人对客观语法的认识。(3)语法教材或语法著作,例如:“这本语法教材写得不错。” 2、语法分析的基本方法是什么? 答:语法分析有两种基本的方法:一是把大类分成小类,例如把词分成名词、动词、形容词等等;一是把整体切分成部分,例如把句子分成主语、谓语等等。进一步要寻求分析出来的单位所涉及的种种关系,包括:语法单位与语法单位的关系,如主谓关系、述宾关系等等;语法单位与客观对象的关系,如施事、受事等等;语法单位与谈话人之间的关系,如陈述、疑问等等 3、什么是词类?为什么要给词分类? 答:词类指的是词在语言结构中表现出来的类别。语法上给词分类,为的是说明语句结构的规则,指明词的用法。 4、汉语划分词类的依据是什么? 答:对汉语的词进行分类,须以词的语法功能为依据。词的语法功能,是指词的组合能力,表现为:(1)能充当什

么句法结构成分,不能充当什么句法结构成分。例如名词经常作主宾语,介宾短语不能作主语。(2)能跟什么词组合,不能跟什么词组合,组合以后发生什么样的关系。例如名词前面可以加数量词,组合后发生偏正关系。名词的前面不能加“不”。 5、举例说明如何区分实词和虚词。 答:根据词能否作句法结构成分,可以把词分为实词和虚词两大类。能单独充当句法结构成分的是实词,例如“人、跑、红、马上”。不能单独充当句法结构成分的是虚词,例如“从、了、吗、和”。 6、举例说明如何区分名词、动词、形容词。 答:可以先用“不”测试,不能加“不”的是形容词。再用“很”测试,能加“很”的是形容词和心理动词;能带宾语的是动词。单音节动词的重叠式是AA,单音节形容词的重叠式是上A 或AA的;双音节动词是ABAB,形容词是AABB。名词主要作主宾语,也可以作定语,动词主要作谓语,形容词主要作定语和谓语。 7、实词包括哪些类别? 答:根据组合能力的不同可以把实词分为体词、谓词、加词三类。体词包括名词、数词和量词;谓词包括动词和形容词;加词包括区别词和副词。另外还有代替以上各类实词的代词。
