第二课 中秋之夜 教学辅助材料(2): 嫦娥三号


《嫦娥飞天 玉兔探月 特别报道》 2013.12.15



From Wikipedia, the free encyclopedia


Chang’e 3 嫦娥三号 lander on the lunar surface, imaged by the Yutu 玉兔 rover


Chang’e 3 (pronunciation:/æŋˈər/; simplified Chinese: 嫦娥三号; pinyin: Cháng’é sān hào) is an unmannedlunar exploration mission operated by the China National Space Administration (CNSA), incorporating a robotic lander and China’s first lunar rover. It was launched in December 2013 as part of the second phase of the Chinese Lunar Exploration Program.[4][5][6]

The spacecraft was named after Chang’e, 嫦娥, the goddess of the Moon in Chinese mythology, and is a follow-up to the Chang’e 1 and Chang’e 2 lunar orbiters. The rover was named Yutu (Chinese: 玉兔; literally: “Jade Rabbit“) following an online poll, after the mythological rabbit that lives on the Moon as a pet of the Moon goddess.[7]

Chang’e 3 achieved lunar orbit on 6 December 2013[8] and landed on 14 December 2013,[9] becoming the first spacecraft to soft-land on the Moon since the Soviet Union‘s Luna 24 in 1976.[10]

第二课 中秋之夜 教学辅助材料: 公历(阳历)和农历两种历法


  据了解,之所以会出现这一现象,最主要是由农历闰月所致。中国目前同时使用国际通用的公历(阳历)和中华民族传统的农历两种历法。阳历是以地球绕太阳公转的运动周期为基础而制定的历法。 但中国传统的农历是以月亮圆缺变化的周期为依据,一个月约29.53天,12个月为354天或355天,比阳历年少了10天~12天。为使得农历年与阳历年能基本对应,中国采取了“197法,即在19个农历年中加上7个闰年,即闰年增加一个月。

中国地图 , 新华字典

Dear students,

Some of you still do not have the 中国地图 and 新华字典(the required versionsbecause there were not enough left from the last school year’s 书展。I will ask the students who have 中国地图 and 新华字典 to share with you during the classes. 

I hope that the bookstore (in NY) will come to the school to hold another书展 soon.  It depends on the bookstore (in NY) if and when they would come to hold the 书展.  I will keep you updated when I have the information.

I strongly encourage the parents to attend the first half hour of the first day class.

Please open the link to my blog and read the contents for this class carefully;

In our first day class, we will start learning Lesson Two: 中秋之夜. “海上生明月,天涯共此时。” 9月8日将迎来一年一度的中秋佳节。
