The Little Red Hen
Once upon a time, there was a little red hen who lived on a farm. One day, she found some wheat seeds and asked the other animals on the farm if they could help her plant them. But the cat, the dog, and the pig all said no.
So, the little red hen planted the seeds herself, watered them, and watched them grow. When the wheat was ready to harvest, she again asked the other animals if they could help her. But, once again, they all said no.
So, the little red hen harvested the wheat herself and took it to the mill to be ground into flour. Then, she asked the other animals if they could help her bake the flour into bread. But, once again, they all said no.
So, the little red hen baked the bread herself and enjoyed it all by herself too. The other animals were jealous and asked her why she didn't share the bread with them. The little red hen replied, "I asked for your help, but you all said no. So, I did it myself."
Moral of the story: If you want something done, you have to do it yourself.
首先，英国在历史上曾经是最大的殖民帝国，其殖民地遍布全球五大洲，使得英语成为了各个殖民地的官方语言。这为英语在全世界的普及奠定了基础。
其次，经济因素也起到了重要作用。在相当长一段时期内，英国经济位居世界首位，而后来美国的经济崛起也起到了推动作用。这些经济体的强大使得英语成为了全球商业和贸易语言，进而在政治、文化等多个领域得到了广泛应用。
此外，英语作为字母文字和表音文字，易于学习和掌握。英语的语法相对简单，使得学习英语成为一件相对容易的事情。而随着科技的发展，各种英语学习工具和资源也进一步降低了学习英语的难度。
最后，全球化的发展也起到了推动作用。随着全球交流的增加，英语作为全球通用语言的优势得以凸显，进而得到了更为广泛的应用和推广。
综上所述，英语能够在全世界普及，是历史、经济、科技以及全球化等多重因素共同作用的结果。
