when and where to build the new factory___not decided yet.(is/are)

Answer 1

Eight times eight____sixty-four.
空里填is，因为主语和表语都是一个抽象的数字。（8乘以8不是两个数字，它们的积是64，所以8乘以8应该看成是一个数字，就是64。）

单独的一个“when+从句”或者“where+从句”做主语，谓语动词用单数。因为从句相当于一个不可数名词。

例如：
When to build，the new factory is not decided.

Where to build the new factory is not decided.

如果“when+从句”和“where+从句”放在一起做主语，那么谓语动词用复数。因为两个从句相当于两个不可数名词。

例如：
When and where to build the new factory are not decided.

以后楼主如果遇到两个不可数名词放在一起做主语，也要记得谓语动词用复数。

例如：
Milk and bread are expensive.

补充:
应楼主要求，询问了一位美国朋友后得到如下回答，根据她的回答，主语确实是复数：

问：In the sentence "when and where to build the new factory ____ not decided." , should the blank be filled in with "is" or "are"?

答： "When and where to build the new factory have not yet been decided" I like better. Subjects are plural: when & where, so use a plural verb. But "have not been" sounds more Americanized than "are not" -- that sounds more British-like to me, but it is also correct. "Yet" is optional, but it suggests that a decision is going to happen some time or another.
(中文翻译如下:我觉得这个句子最好写成"When and where to build the new factory have not yet been decided".主语when和where是复数，所以动词也用复数。“have not been”听起来更像美式英语，而“are not”则更像英式英语，不过两者都是对的。“yet”可有可无，如果用了“yet”就表示“决定”这个动作将来会发生，如果不用则表示将来也不一定会发生。)

唉，楼主，得你这个最佳答案可真难啊。呵呵。一定要记得处理问题哦。

Answer 2

is,把Eight times eight作为一个整体来看 八乘以八等于六十四 八乘以八作为一个主语 是一个整体 一个意思 所以用单数

when+从句 作主语时谓语动词用单数
where+从句 作主语时谓语动词用单数
when+从句+where+从句作主语时谓语动词用复数

仍旧是is 因为只有一个to do

Answer 3

单数
