一英语的起源与发展

（1）英语（英文：English）是一种西日耳曼语，最早被中世纪的英国使用，并因其广阔的殖民地而成为世界使用面积最广的语言。英国人的祖先盎格鲁部落是后来迁移到大不列颠地区的日耳曼部落之一，称为英格兰。

（2）自17世纪以来，现代英语在英国和美国的广泛影响下在世界各地传播。通过各类这些国家的印刷和电子媒体，英语已成为国际主导语言之一，在许多地区和专业的环境下的语言也有主导地位，例如科学、导航和法律。

二如何学习英语

（1）多听电视台新闻，习惯英语，看节假日的晚会。 现在电视节目有很多，比如新闻频道里节目主持人，他们说的英语都是很标准的，是值得学习的，多听，自己的方言就会改进。

（2）英语词汇量过关，说好英语。小时候，没学好单词，对于声母和韵母读的不标准，现在长大了学，也不难，一个月到三个月就可练习好，要经常试着用英语来说话，这样方便与人们交流。

arch的基本意思是“拱,拱门”,用于比喻则表示“拱形物”。前缀arch-来源于希腊语的拉丁化前缀arkh-, arkhi-,意思是“chief, principal; extreme, ultra; early, primitive”，意思：主要的，总的。前缀archi-,arche-是前缀arch-变化型。当作为活用前缀时，一般加在人称名词上，通常还具有轻蔑效果，如：arch-liar 大骗子，这个构成单词能力一般一般可自由地与名词结合，构成新词。其中，主要是与人有关的名词，如：archduke。另外，arch 可以独立为形容词，如：arch smile 狡猾的微笑。
