美国数学竞赛(AMC)

2016年2月3日

一.赛事介绍

1950 年美国数学协会Mathematics Association of America （简称MAA），开始举办美国高中数学考试（AHSME）。在1985年时，MAA又增加了初中数学的考试（AJHSME），2000年以后这些考试统一被称为AMC，AMC总部现设在美国加州內布拉斯加大学林肯校区。每年仅在北美地区正式登记参加比赛的学生就超过60万人次，因此AMC是世界上目前信度最高的数学科测试。此项测试已获美国中学校长们推介为各学校每年的主要活动。

AMC测试的试题研发、命制到统一阅卷等工作由AMC主试委员会全权负责。该委员会由以数理闻名的内布拉斯加大学林肯分校数学系的专家和来自其它全美一流学府，如麻省理工学院（MIT）、哈佛大学（Harvard）、普林斯顿大学（Princeton）等名校的专家组成。

主谓一致用法详解及练习题 附答案

．主谓一致 主谓一致是指一个句子的主语和谓语动词保持数的一致关系。英语主谓一致一般要遵循三条原则，即：语法一致原则；意义一致原则和就近原则。 1.语法一致原则 语法一致原则是指谓语动词和它的主语在语法形式上必须取得一致，即主语是单数形式，谓语动词用单数形式，主语为复数形式，谓语动词也用复数形式，如： Tom doesn’t like swimming. 汤姆不喜欢游泳。 Jane and Mary look alike. 简和玛丽看起来很像。 2.意义一致原则 意义一致原则是指谓语动词和主语的一致，同由主语所表达的单数概念来决定，而不是根据主语的实际语法形式。 有时主语的语法形式是单数，但所表达的概念是复数意义，这时动词应采用复数形式，如： The football team are having breakfast now. 足球队员们在吃早饭。 The news was exciting. 这条消息令人振奋。 3.就近原则 就近原则指谓语动词的人称和数要在形式上与最靠近它的那个名词或代词取得一致。当一个句子有两个主语而它们又是either...or…, neither…nor…, not only…but also…, or 等连接时，谓语动词与靠近它的主语保持一致，如： Either your students or Mr Wang knows this. 你的学生们或王老师知道这件事。 Neither Jim nor his friends were interested in this film. 汤姆和他的朋友们都对这部电影不感兴趣。 主谓一致这三个原则中有很多需要注意的问题， 1.主语为集体名词 (1)某些集体名词既可表示单数也可表示复数。如果集体名词作为一个整体看待，谓语动词用单数形式，如果就其中一 个成员而言，谓语动词用复数形式，如： Our group were discussing heatedly on the subject. 我们小组成员正对这个问题进行热烈的讨论。（group 指小组成员）Our group is made up of four girls and five boys. 我们小组有4个女孩和5个男孩组成。（group 指小组整体） The population in China is very large, and one third of the population are farmers. 中国的人口很多，其中三分之一是农民。（前一个population 指整体，后一个population 指成员） (2)某些集体名词如people, police, cattle, youth 等常作复数看待，谓语动词与复数形式的谓语搭配，如： The police are searching for him. 警察正在搜寻他。 The cattle were driven away from the hill. 那些牲畜从山上被赶走了。 3.某些名词如equipment（设备），furniture（家具），jewelry（珠宝），clothing（衣服），machinery（机械），表示单数 概念，谓语动词要相应地采用单数形式,如： A lot of equipment has been replaced by the new equipment. 许多旧设备已经被新设备代替了。 All the machinery in the factory was controlled by robots. 这个厂所有的机械都由机器人来控制的。 2.主语为代词 (1)．有些代词尽管意义上是多数，但谓语动词要用单数形式，这类代词有：either, neither, each, another, somebody, someone, something, anything, anyone, everyone, everything, everybody, no one, nothing, nobody 等，如： Neither likes the friends of the other. 两人都不喜欢对方的朋友。 Everything around us is matter. 我们周围所有的东西都是物质。 注意： ①在neither of 与either of 的结构中，谓语动词可用单数形式也可用复数形式，如： Neither of them was / were in good health, but both worked hard. 他们俩身体都不好，但工作却都很努力。 ②each 用于单数名词前，谓语动词用单数形式, each 用于复数主语后，谓语动词用复数形式。each of, each one of 后 接复数名词或代词，但谓语动词常用单数形式。 Each (one) of the houses was different. 每座房子都不同。 Each student has been given their own e-mail address. 每个学生都得到了一个自己的电子邮件地址。
