But it was a long and uphill journey for compilers to create the dictionary in Mandarin Chinese from scratch. They started the project in the 1950s when most dictionaries on the market were written in Classical Chinese and had been outdated.
但是对于编纂者来说，从零开始编写汉语词典是一个漫长而艰难的过程。他们在20世纪50年代开始编写，当时市面上大多数词典都是用文言文编写的，已经过时。
from scratch：从头开始
"Telegraph" was among more than 56,000 entries in the first edition of the dictionary, new to Chinese at that time.
“电报”是首版《现代汉语词典》收录的超过5.6万个词条之一，这在当时还是新鲜事物。
entry[ˈentrɪ]：n.条目

72岁的李向国（音）回忆起20世纪80年代初电报的全盛时期，当时他在中国西北的陕西省当公务员。当时，中国人主要通过电报传递信息。
heyday [ˈheɪdeɪ]：n.全盛期
"Telephone sets were not widely available in the whole county. Telegraphers were very busy tapping on the keys of the telegraph machines every day," Li said.
他说：“当时，电话机在全县并不普及。电报员每天都忙着收发电报。”
Long gone are the days when people mustered enough patience to wait hours, days or weeks for their messages to get through. Nowadays, messages can be delivered through a few taps on a handheld screen.
人们耐心地等待数小时、数天或数周才能收到信息的日子已经一去不复返了。如今，只需在手持设备的屏幕上轻敲几下就可以传递信息。

高志军（音）一直都忘不了他买到第一台DVD播放机的那一天。1997年，他花了2000多元买了一台DVD播放器，这大约是他三个月的工资，当时这种设备在中国有售，但价格昂贵。

"It is noticeable that the impact of the internet is ubiquitous in the Modern Chinese Dictionary," Tan said. "QR code" was added in the latest edition of the dictionary published in 2016.
谭景春说：“值得注意的是，互联网的影响在《现代汉语词典》中无处不在。”2016年最新出版的词典中加入了“二维码”一词。
ubiquitous [juːˈbɪkwɪtəs]：adj.普遍存在的；无所不在的
