主谓一致的考法：

　　1、单数或复数主语+一个大长串同位语/定语从句/分词短语/+谓语【此时划线考基本已经看晕句子的考生主谓一致】

　　2、未划线部分是it，its，they，their，然后划线部分考看题时忽略未划线部分的考生主谓一致，例如the sloth还是sloths要考隔了很远后面的its toes…根据its来选the sloth+谓语第三人称单数 见OG11-127

　　3、主语+谓语+单数或复数宾语+插入成分很长一串+宾语从句【此时在宾语从句的谓语下划线考你主谓一致，考生千万别忘记了看清楚宾语是谁】新prep破解sc1-182

　　4、一个名词的修饰成分很长，要有能力辨别清楚中心词是谁，主谓一致这个“主”是谁，例如 the number of people，a successful grassroots campaign，要能看到number和campaign是中心词，不要别其修饰成分中某复数给骗了，或者看着看着就忘记句子主语中心词是谁，只有个某某复数的印象而选了错误的谓语形式。

　　5、常在each和all上做文章。经常是让你选划线部分用each还是all，关键是你要看到未划线部分是a或者an还是复数的名词，不要盲目去选。

　　所以以后看到单数名词或者复数名词稍微警觉一下，以防GAMT隔了很远出主谓一致。

　　an average of+复数名词 作主语：谓语动词用复数

　　the average of+复数名词 作主语：谓语动词用单数

　　One of 主谓一致

　　one of + 复数名词 + 单数谓语；

　　eg： One of my friends is in the US.(强调one)

　　one of + 复数名词 + 定语从句(从句复数谓语) + 主句谓语单数；

　　eg： One of my friends who are in the US will come to China.(强调friends)

　　only one of + 复数名词 + 定语从句(从句单数谓语)；

　　eg： Only one of my friends who is in the US will come to China.(强调only one)

　　By LZM：

　　LZM的书里有很详细的注解：

　　1〉'one of' 结构作为主语时+V，'two of' + Vs

　　2> 'one of + n(pl.)+that/who'+V，因为在GMAT当中that，which，who 都closely follow the subject they modified， 所以他们都修饰n(pl.)

　　3>the only one/the first one of...+Vs

　　P.S. numbers of +n[c] ALWAYS WRONG

　　large sums of/quantities of +n[U]+V：e.g. large sums of water ARE

　　经典举例：

　　大全940.With its plan to develop seven and a half acres of shore land， Cleveland is but one of a large number of communities on the Great Lakes that is looking to its waterfront as a way to improve the quality of urban life and attract new businesses.

　　(A) is looking to its waterfront as a way to improve the quality of urban life and attract

　　(B) is looking at its waterfront to improve the quality of urban life and attract

　　(C) are looking to their waterfronts to improve the quality of urban life and attract

　　(D) are looking to its waterfront as a way of improving the quality of urban life and attracting(C)

　　(E) are looking at their waterfronts as a way they can improve the quality of urban life and attract
