在小学读书时,语文老师曾经告诉我们,汉语的词汇是世界上各种语言文字中最丰富、最精彩的一种,内涵丰富,耐人寻味,有一些词汇在使用过程中还会出现转义或变味.现在,社会上有很多新的“热门话题”,有些词汇也就因“热”而变,“考察”就是其中之一,有时变成“公费旅游”和“出国观光”. When I was in primary school, the language teacher once told us that the Chinese vocabulary is one of the richest and most exciting languages ​​in the world, rich in content and thought-provoking. Some of the words may also escape or become unpleasant during use Nowadays, there are many new “hot topics” in the society, some of which have become “hot”, and one of them is “study”, which sometimes becomes “free travel” and “going abroad”.
