A B B
both 表示两着都… 是个副词,也可以做代词,例:
副词:We are both students.
代词:Both of us are students.
它的否定形式是neither 词性和both一样,例:
副词:We are neither STUDENT,注意是单数名词.
代词:Neither of us IS a student 同样注意也是单数
one of +名词复数 而后面的谓语动词要用单数 因为中心语是 one of
thunderstorms是雷雨得意思,用复数
如果用and连接的两个词语（为可数名词）表示两个事物的概念,就应该用be动词are.但用and连接两个两个词语表示一个事物,或都在英语中的习惯的用法用is,such as 说针和线时就用is.一个不可数名词和一个可数名词用and连接要看所表示的概念,是一个整体用is.其它用are.
多个单数名词作主语比如：A and B时,谓语用复数；A (together)with B时谓语就A.你可以查看中学英语语法书啊!

A B B

1.A(are=多过一个，statues=很多雕像)
2.B(一个就用was)
3.B(thunderstorms=很多闪电，就用are)

1.A因为是两个，所以用复数形式are
2.was，没有在英语里当作单数
3.are，因为这个是thunderstorms是复数形式。
