“因为玩音乐快乐,因为玩音乐的生活让我有存在感,有双脚踏在地上的感觉,直到听音乐入了神,才能脚尖一掂,轻轻飘飘地浮在太空.在太空中回过头,你会看到一颗蓝得令人心疼的大弹珠,那是我所有成长回忆的地方.我看着上面的岛屿山峦,密布着蛛网小径,发现了我遗忘已久的足迹和回忆.”——阿信

假设没有其他输入（input），在一个周内，英国能生产8码布或者2桶酒；葡萄牙能生产12码布或者6桶酒。问题：如果两国之间没有贸易，那么就英国生产的布来说，它的酒是多少钱？ 是根据英文翻译的，可能翻译的不好，我把英文也打下来。
the following table describe the number of yards of cloth and barrels of wine that can be produced with a week's worth of labor in England and Portugal. Assume that no other inputs are needed. Q: If there is no trade, what is the price of wine in terms of colth in England? 表格就是上面用中文描述的多少码布和多少桶酒的那个，很简单的表格，如果是高手的画，不画表格也应该会做的。

抛物线,球解答啊,谢谢谢谢谢谢
