高速铁路，就是设计标准等级高、能让列车高速运行的铁路系统。世界上第一条正式的高速铁路系统是1964年建成通车的日本东海道新干线，沟通东京、名古屋和大阪所在的日本三大都市圈，促进了日本的高速发展。其设计速度为200km/h，因此高速铁路的初期速度标准就是200km/h。

High-speed railway is a railway system with high design standards that can allow trains to run at high speeds. The world’s first official high-speed railway system was the Tokaido Shinkansen in Japan, which was completed and opened to traffic in 1964. It connects the three major metropolitan areas of Japan, including Tokyo, Nagoya and Osaka, and promoted Japan’s high-speed development. Its design speed is 200km/h, so the initial speed standard of high-speed railway is 200km/h.

开学，汉语解释有开设学校、启作学者、学期开始三个释义。但在日常生活中用的比较多的是学期开始。现代汉语中开学通常指学生们经过假期的休息之后，重新返回学校继续学习。根据国家与学制不同，每年的开学日会有2-4个，代表一个新学年开始的开学日一般会进行仪式。

The Chinese meaning of “start of school” is “opening a school”, “starting scholars”, and “start of the semester”. However, the term “start of the semester” is more commonly used in daily life. In modern Chinese, the start of school usually refers to students returning to school to continue their studies after a holiday break. Depending on the country and the school system, there are 2-4 start days each year, and a ceremony is usually held on the start day of a new school year.
