简单初中英语问题

Question

比如说another two hours 整个词组看成单数还是复数？
是Another two hours is enough. 还是Another two hours are enough.
还有two more hours之类类似的
很简单，但请认真回答，瞎猜的就算了，最好能讲下理由

Answer 1

是Another two hours is enough. =two more hours is enough 表示时间、距离、金钱、重量等作主语时谓语动词用单数

Answer 2

Another two hours is enough。对。
another two hours这个短语是个整体。

Answer 3

英语中，表示时间、距离、度量衡，尽管名词是复数形式，但谓语还是用单数。
e.g. Another two hours is enough.
Ten dollars is enough.
Two years is too long.

Answer 4

是复数。根据翻译“另外的两小时”，可得是复数。
