选项

答案K

解析 动词辨析题。分析句子结构可知,本空位于主语universities和宾语research data之间,因此应填入动词作谓语。本句意为,大学把研究数据______到因特网上,学生不用离开宿舍就能找到信息。由后半句可知,学校的数据放到网上,学生足不出户就能找到信息。因此本空应填入含有“上传”含义的动词,故答案为K)posted“发布,张贴”。该处易误填N)submitted,submit指“将计划、报告等交给权威人士以供其参考或批准”,通常构成的搭配为submit sth.to sb.,而post是将文件放到网上以供人们浏览,通常构成的搭配是post sth.on the Internet,其他备选动词均不能与research data(研究数据)搭配,故排除。
