is his money enough for a tin of dog food?这句话对吗?

Does he have enough money for a tin of dog food?在通常情况下,enough不能用作表语,除非其主语是代词或是那些具有（或暗示有）数量意义的名词。如：One such dictionary is enough。 这样的词典一本就够了。Five men will be quite enough。 5个人完全够了。I did all I could, but it wasn’t enough。 我做了我能做的一切,但是还不够。比较下面的正误句子：误：The beer isn’t enough。 啤酒不够。正：There isn’t enough beer。 啤酒不够。误：Was the time enough? 时间够吗?正：Did you have enough time? 你们时间够吗?http://baike。baidu。com/view/432231。htm 再问： it is about 2 hours from SH to NJ by plane 这句话对吗？ 再答： 个人觉得，不太合适的。应该说：It takes about 2 hours to fly from SH to NJ。或It takes about 2 hours to travel from SH to NJ by plane。
