主谓一致问题主谓一致是指主语与谓语在数上要一致。把握主谓一致问题，考生主要解决的是对不同结构的主语单复数的认定，进而选择适当的谓语。解决主谓一致主要遵循三个原则：语法一致原则意义一致原则就近一致原则很多情况下应该综合利用这三个原则来处理主谓一致，在不同情况下可能应用三个原则中的不同原则，具体应用哪种原则应该视具体情况而定。总结如下：
一。谓语动词用单数的情况
1.动名词短语、不定式短语、名词性从句做主语，谓语用单数。
如：Buying clothes is often a time-consuming job because those clothes that a person likes are rarely the cones that fit him or her.
To understand the situation completely requires more thought than has been given thus far.
2.表示时间、距离、金额、重量、面积、体积、容积等度量的名词短语做主语时，谓语用单数。
Two weeks was too long Five times five makes twenty five
3.一般用and连接的两个单词或短语做主语时候，谓语用复数，但是下面用and连接的主语表示一个概念，谓语用单数：
law and order法制 soap and water肥皂水 a cup and saucer茶杯碟子 fork and knife刀叉 the needle and thread针线 trial and error反复尝试，不断摸索 horse and carriage马车 time and tide岁月 bread and butter 奶油面包 the ebb and flow 盛衰，潮涨潮落
