First of all online classes are very convenient. Students can acquire knowledge whether they are near or far away as long as they have the network and the ability to operate the computer. Secondly students can repeatedly watch and download lecture videos electronic lesson plans and other contents to reviews and improve the problems they don't appreciate in class.
But online classes should always face the screen of electronic products. Too long a time will lead to vision loss. Second if self-control is not strong the efficiency of online class will be reduced. In addition the effort of online class is deeply affected by the network signal. If the network is not good the effect of classroom learning can not be guaranteed.
To sum up the way of network teaching has advantages and
disadvantages.However there are more ways than difficulties. As long as teachers and students work together these problems can be solved so that all students can become the real \"audience\" of online classes the real beneficiaries!

随着互联网的发展，一些学校开始采用网络教学的方式。
首先，网上上课很方便。只要学生有网络和操作计算机的能力，他们就可以获得知识，无
论是近的还是远的。其次，学生可以反复观看和下载讲座视频、电子教案等内容，对课堂上不欣赏的问题进行复习和改进。
但在线课程应该始终面对电子产品的屏幕。时间过长会导致视力下降。二是自制力不强，会降低网络课堂的效率。另外，网络信号对网络课堂教学的效果也有很大的影响。如果网络不好，课堂学习的效果就无法保证。
综上所述，网络教学方式具有优势但是，缺点有比困难更多的方法。只要师生共同努力，这些问题都能得到解决，让所有学生都能成为网络课堂的真正“受众”，真正的受益者！
