感谢WSY童鞋批改
With the development of the high technology, the electronic media, such as television and movies, has an increasing effects on society.
这句话with是伴随状语,the electronic media作为主语是单数,such as...是插入语,谓语时has,所以谓语应该与主语电子媒体保持一致,所以是单数
Many public courses from famous universities all over the world will be made available free to the public
这句里面的free我想做动词来着,是be made do sth. 好像表达上是有点别扭,但是我也没想通是什么问题。。。
