鳄鱼与河马:这句话对吗？

你仔细读读我的修改：

Using the modernized audio-visual facilities/programs,students can acquire the needed information instantly without being restricted by time and space.

你写的句子大约是介于6级作文的水平，但是语法有点错误，也不够流畅。这是我的意见，坦白的。

Using the modernized audio-visual which can make students not restricted by time, space, receive the information of the things in time

This is not a complete sentence.

It should be:

Using the modernized audio-visual (media) can make students receive the information of the things in time, not being restricted by time and space.
or:
Using the modernized audio-visual (media) can make students, not being restricted by time and space, receive the information of the things in time.

主语: Using the modernized audio-visual (media)
句子结构是:
Something can make someone do something.

100% correct
全对

这个句子造得很好

不对,visual-audio是形容词后面应该加名词devices/apparatus/equipment正确的结构是make sb. not do sth.所以not后面要加be,同时两个动作也应该由and连接因此改为:
Using the modernized audio-visual devices which can make students not be restricted by time, space and receive the information of the things in time.

我觉得which应该换成that
