在语法复习过程中,如果能把各语法知识要点“化零为整”进行概括归纳,不仅能减轻学生的记忆负担,而且能使学生更清晰地把握语法脉络,从而更有效地掌握语法知识点。 笔者发现主谓一致语法板块中细节要点较多,因此就把这些琐碎的要点集中在一起进行分类归纳。最后,把二十多个细节要点分成了七大类。在复习过程中,以七大要点为大线索的同时,顺势引出其中的细枝末节。在以后的巩固记忆中,学生会感到更方便一些,或者说眉目更加清晰。 主谓一致包括意义一致与语法上的一致。要注意以下要点: 一、and 连接并列成分 1. and 连接并列成分表示不同的人或事物作主语的,谓语动词用复数。 2. and 连接并列成分表示同一个人或事物作主语的,谓语动词用单数。 试比较: Hard work and much play are both necessary for us. All work and no play makes Jack a dull boy. 二、就近原则类 连词or, either...or, neither...nor, not only...but also, not...but, there be 等连接两个并列主语时,谓语的数与最靠近它的主语保持一致。如: Here are some envelopes and paper for you. Not he but Jane and Mary have been invited to the party. 三、主语+插入语类 主语后面接以下介词或连词连接的说明主语的修饰词或插入语:with, along(together)with, as well as, like, rather than, but, except, besides, including等。谓语动词的数不受修饰成分的影响,仍与主语保持一致。如: The driver, rather than his friends, was responsible for the accident. 四、特殊名词类 1. 集体名词作主语时,表示整个集体的,用单数谓语动词,强调其中成员时,谓语动词应为复数。常见的集体名词有:group, family, team, class, army, government, population, crew, nation等。如: 80% of the population of China are farmers. The population of China is larger than any other country in Asia. 2. 集合名词作主语时,只能表示复数概念。常见的集合名词有:cattle, police, public, people等。如: The police are searching for the escaped prisoner. The public are calling for better housing and working conditions. 3. 只有复数形式的名词作主语,谓语动词用复数。常见的有:glasses, scissors, trousers, clothes,goods等。如: All the goods have been shipped abroad. The trousers are not fit for me. The pair over there is better. 以-s结尾的名词表示学科名,病名,游戏名,国名,书名等时,谓语动词用单数。如: The Arabian Nights is well known to the English. 比较: Each means has been tried. 五、抽象概念名词作主语类 1. 主语是不定式、动名词或从句时,谓语动词一般为单数。如: To catch what he said was not difficult. When and whether we will go camping hasn't been decided. 试比较: What we need are more useful materials. What they need is more time. 2. 主语是定冠词接形容词或分词表示抽象概念的事物时,谓语动词用单数,表示一类人时,用复数。如:the rich, the deaf, the sick, the wounded, the oppressed, the poor, the old, the blind, the dead等。如: The best is to come. The rich are not always happy. 3. 表示时间、距离、金钱等度量衡名词作主语时,谓语动词常因把主语视为整体而常用单数。如: Two thousand dollars is a big sum of money for me. 4. 数学算式作主语时,谓语动词通常用单数。如: Three times two is six. Five and five makes ten. 六、不定代词类 1. something, everything, nothing, everybody,little,much 等不定代词作主语时,谓语动词用单数。如: Little has been done to control pollution. 2. few, many, how many等不定代词作主语时,谓语动词用复数。如: How many work in the company? 3. all, most, the rest, a lot 等作主语时要视情况而定。如: Most of the country is flooded in the water,and most of the people are suffering. All are present and all is going on well. 七、限定词类 限定词修饰名词作主语时,谓语动词的数通常与被修饰的名词保持一致。 1. 限定词 a lot of, plenty of,...percent of,most of, the rest of, all of,后接可数或不可数名词,谓语动词的数与名词相对应。如: Two thirds of the books are newly published. All of the apple has gone bad. 2. 限定词 many a, more than one 后接名词单数时,谓语动词用单数。every, each, no,many a 修饰名词单数,and连接两个并列短语时,谓语动词也用单数。如: Every boy and every girl wishes to go to attend the party. 3. a number of, the number of 的用法直接影响主谓一致问题。如: The number of people who go to college keeps climbing these years. A number of people were injured. 4. a quantity of / a mass of 后接可数名词单复数或不可数名词时,谓语动词一律用单数。quantities of / masses of 后接可数名词单复数或不可数名词时,谓语动词一律用复数。 根据以上归纳的要点,要求学生在记忆时应善于以点带面。当然,在记忆的基础上,更应强调的是对主谓一致的实践运用能力的提高。在一些简单句型中会熟练运用这一知识,在一些较复杂句中同样要注意主谓一致。 1. 在定语从句中要注意主谓一致。如: All that has been done is of little help to us. All who are here have not been invited. 2. 在强调句中要注意主谓一致。 如: It is writing that makes what we read ours. 3. 在倒装句中要注意主谓一致。如: There,lying on the floor, were some mice rather than his pet cat.
