考博英语语法基础讲解：语法一致原则
　　5. 在定语从句时，关系代词that， who， which等作主语时，其谓语动词的数应与句中先行词的数一致。如：He is one of my friends who are working hard. / He is the only one of my friends who is working hard.
　　6. 如果集体名词指的是整个集体，它的谓语动词用单数;如果它指集体的成员，其谓语动词就用复数形式。这些词有family， class， crowd， committee， population， audience等。如：Class Four is on the third floor. / Class Four are unable to agree upon a monitor.
　　注意：people， police， cattle等名词一般都用作复数。如：The police are looking for the lost child.
　　7. 由“a lot of， lots of， plenty of， the rest of， the majority of 名词”构成的短语以及由“分数或百分数 名词”构成的短语作主语，其谓语动词的数要根据短语中后面名词的数而定。如：There are a lot of people in the classroom. / The rest of the lecture is wonderful. / 50% of the students in our class are girls.
　　注意：a number of“许多”，作定语修饰复数名词，谓语用复数;the number of“……的数量”，主语是number，谓语用单数。
　　8. 在倒装句中，谓语动词的数应与其后的主语一致。如：There comes the bus. / On the wall are many pictures. / Such is the result.
