英文阅读---英语中“闰年”怎么表达，（初中适用，附语言知识点、填空练习） 什么是闰年？为什么2020年是闰年？ 2020 is a leap year! Superman has a birthday this year. Superman and anyone else born on February 29 only get the day of their birth every four years, in a leap year (闰年). On this year’s calendar, February 29 is there! It’s because the calendar the world uses is based on the time it takes for the Earth to orbit (绕……运转) the Sun. But the Earth doesn’t orbit the Sun in exactly 365 days. In fact, it takes 365 days and about one quarter of one day for the Earth to complete its full orbit. The calendar manages this by making the regular year 365 days, and every fourth year — called a leap year — we get an extra day, called a leap day. Leap years have 366 days. Non-leap years are called common years. The internationally accepted calendar is called the Gregorian calendar. It’s also known as the Western or Christian calendar. It is named after the Catholic Pope (天主教教皇) Gregory ⅩⅢ, who introduced it in 1582. The rule for leap years is: every year that can be divided by four is a leap year, except for years that can be divided by 100, but these centurial (一世纪的) years are leap years if they can be divided by 400. 本文来源：https://www.wddqw.com/doc/79b1b43900020740be1e650e52ea551810a6c99d.html
