Question

请问这道题填哪个

Answer 1

填are，因为and前后不是同一事物

1、当and连结的两个名词是指同一个人或同一件事，and后的名词前没有冠词，谓语动词应该用单数形式；在and后面的名词前有冠词，谓语就用复数形式。
例如：
1)The bread and butter is served for breakfast. (早饭供应黄油面包。)
2)The bread and the butter are on sale. (正在出售黄油和面包。)

2、用and连接的单数主语，前面有each, every, many a, no等修饰时，谓语动词要用单数形式。复数主语与each连用时，应不受each的影响，谓语动词仍用复数形式。
例如：
1) Each pen and each paper is found in its place.
2) Every boy and girl is treated in the same way.
3) Many a boy and many a girl has seen it.
4) The old workers and the young each have their own tools.
