The analysis of 74,000 short stories found that their written work was littered with Americanisms, exclamation marks and references to celebrities.
Researchers who looked at the entries to a national competition found they were increasingly using American words such as garbage, trash can, sidewalk, candy, sneakers, soda, cranky and flashlight.
研究人员阅读了全国作文比赛的参赛作品后发现，，孩子们正越来越多地使用一些美式英语词汇，比如：garbage（垃圾）, trash can（垃圾桶）， sidewalk（人行道）, candy（糖果）, sneakers（胶底运动鞋）, soda（苏打水）, cranky（暴躁的） and flashlight（手电筒）。
The stories, written by pupils aged seven to 13, show how fairy cakes are referred to as cupcakes and a dinner jacket has become a tuxedo. ‘Smart’ is now often used for ‘clever’ and ‘cranky’ for ‘irritable’.
Researchers also found that punctuation was underused, especially semi-colons and speech marks. Some did not know how to use capital letters.
However, exclamation marks were overused. Researchers found 35,171 examples in total, with some young writers using five at a time. The study of more than 31million words will be compared with future research to see how written language evolves.
