如in the 1990s ,in 1990s

in the 1990s一般in为介词,the 1990s相当于名字的样子,例如:

The late 1990s were a very happy time for lucy 相当的短语有:the Early 1990s,the end of 1990s,而in the 1990s是做状语的,

in 1990s是指一个时间,一个年代了.in the 1990s 是指在二十世纪90年代的意思.

in the 1990s:在20世纪90年代

in the 1990's:在20世纪90年代的

during the 1990s:在20世纪90年代期间

during the 1990s':在20世纪90年代期间的
