信息技术课堂导入的外文文献，很多,是个人原创。

免费的外文文献，可以到OA图书馆查询。
输入相应的英语关键词即可。

免费下载论文有如下几个方法：
1、可以百度一下相关的论坛，像是“小米粒资源网”等，里面有免费的试用账号，可以在一段时间内免费下载论文！
2、一些高校的IP地址都是购买了中国知网的下载版权，每年是十几万的版权费吧，我们学校就是这样，所以到高校的图书馆或者电子阅览室下载是免费的！
3、百度知道有人（如楼上的那几位“QQ是XXX”的几位）购买了账号，你可以在百度知道提问题求助，但是财富值和RMB的价格也不菲！
4、所以，我推荐你到一个湖南省图书馆建立的“联合在线咨询”论坛去发帖求助下载（百度一下“联合在线咨询”），也是免费的！ 我自己也是在这个论坛下的！
