我在某网站看到这么一个对比:
A black and a white dogs are playing in the yard. 一只黑狗和一只白狗正在院子里玩。(两只狗)
A black and white dog is playing in the yard. 一只黑白花狗正在院子里玩。(一只狗)
该网站认为这两句话都是对的。但是我对A black and a white dogs are playing in the yard.是否正确存在疑问。这种说法正确吗?
类似的,An apple and a coconut trees are in the park. 这个句子是否正确呢?
谢谢!
