一般情况下，主谓之间的一致关系由以下三个原则支配： 语法一致原则、 意义一致原则和就近原则一、语法一致主谓一致的原则指主语和谓语从语法形式上取得一致:主语是单数形式,谓语也用单数形式;主语是复数形式,谓语亦用复数形式. 如: He often helps me learn English.　　(主语是单数,谓语也用单数形式) 　.My friends often help me learn English.　　(主语是复数,谓语也用复数形式)1、不定式,动名词,以及从句作主语时应看作单数,谓语动词用单数.如: Reading aloud is helpful to learn English.大声朗读对学习英语是有帮助的What he said has been recorded . 他说的话已被录音了.2、不定代词one, every, each, everybody, everyone, one of, no one, nothing, nobody, someone, somebody, either, neither, many a 等作主语或是修饰主语时应看作单数,谓语动词用单数.但none 作主语时,谓语动词既可用单数也可用复数,这要取决于说话人的看法。

如: Neither of my sisters likes sports . 我的妹妹中没人喜欢运动.Every boy and girl shows great interest in this book . 每个男孩和女孩对这本书都表现出很大的兴趣.3、表示国家,机构,事件,作品等名称的专有名词作主语时应看作单数,谓语动词用单数.如: One Thousand And One Nights tells people lots of interesting stories . 　　《一千零一夜》给人们讲了许多有趣的故事4、 a kind of, the number of等与名词构成名词短语作主语时应看作单数,谓语动词用单数.如: A kind of rose in the garden smells very pleasant.这座花园里有一种玫瑰香气怡人.5、由some, several, both, few, many, a number of 等词修饰主语,或是由它们自身作主语时应看作复数,谓语动词用复数.另外,由and连接两个主语时,谓语一般用复数.如: Both of us are fond of watching football games.我们俩都喜欢看足球赛.6、由“分数或百分数+of +名词（或代词）”以及由a lot of, most of, any of, half of , some of, none of, the rest of , all of等加名词构成的短语作主语时，其谓语动词的数要与of后面的名词（短语）保持一致。

如：30 percent of the students in our class are girls. 我们班的30%是女生A lot of money in the shop was stolen yesterday. 昨天那家商店丢失了许多钱.7、population 单独使用作主语时，谓语动词用单数；而前面有some, most 或与分数、百分数连用作主语时，则谓语动词用复数形式 如: The population in our country is very large, and eighty percent of the population are farmers. 我们国家人口众多，而80%的人口是农民二、意义一致从意义上来解决主谓一致问题，有时主语形式上为单数,但意义上却是复数,那么谓语根据意义也用复数形式;而有时主语形式上为复数,但意义上却是单数,那么谓语根据意义亦用单数形式.1.当主语后面接由but, except, besides ,as well as, as much as, including,more than,no less than, rather than, together with等引导的词组时,其谓语动词的单复数形式通常由前面的词来决定。

如: The students, together with their teacher , are going to have a picnic this weekend.学生们打算这个周末与他们的老师一起去野炊.这时可以将上面句子。
