有呀！应该把w追答把are 改为 is因为后面是单数a teacher追问整句应该怎么改？写给我追答There is a teacher and some studentd in our classroom.students追问teacher和student是两个主语吗？追答是并列在一起作主语

他答错了，there是表复数的应该是This is

There are a teacher and some students in our class没有错误，因为and不是临近原则，而是相加原则，和在一起超过1，所以用are是妥妥的。临近原则有either等追答摘要：there be句型be动词单复数取决于其后的主语.如果其后是由and连接的两个主语.则应与靠近的那个主语保持一致.如:There are two chairs and a desk in the room.. 注意:Here引导的句子用法同上.如果是一般谓语动词，表示复数信息，就用复数students and a teacher are in the classroom，反之单数a dancer and teacher is my mum

改为：There is a teacher and some students in the classroom.
在There be... 句中，如有两个以上的名词作主语时，be 动词与靠近的名词的数保持一致。与 a teacher 一致的是： is
