The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign state located off the north-western coast of continental Europe. The country includes the island of Great Britain (a term sometimes loosely applied to the whole state), the north-eastern part of the island of Ireland, and many smaller islands.
大不列颠及北爱尔兰联合王国，又称为联合王国或英国，是一个主权独立国，位于欧洲大陆西北部。它由大不列颠岛（在不严谨的情况下，有时也用来指整个国家）、爱尔兰岛的东北部和许多较小的岛屿构成。
So here is the difference between the United Kingdom, Great Britain, and England. Great Britain is the name of the island northwest of France and east of Ireland which consists of three somewhat autonomous regions: England, Wales and Scotland. Therefore, England is part of Great Britain, which is part of the United Kingdom. The U.K. includes Great Britain and Northern Ireland. England, Wales, Scotland, and Northern Ireland are not independent countries but the United Kingdom is.
英国、大不列颠以及英格兰所指的地区是有区别的。大不列颠指的是法国以西以北的岛屿以及爱尔兰岛的东部，它包括3个自治区：英格兰、威尔士以及苏格兰。因此，英格兰是大不列颠的一部分，而大不列颠是英国的一部分。英国由英格兰、威尔士、苏格兰以及北爱尔兰组成。英格兰、威尔士、苏格兰以及北爱尔兰不是独立的国家，英国才是。
