2. 網(wǎng)絡(luò)公開課有不少好處，也存在一些問題;
3. 我對此的建議。
范文：
Online open courses are gaining popularity in recent years. Following globally famous universities like Yale and Harvard, some universities in China have also started to offer online open courses. Those courses have attracted people from all classes with different occupations.
The courses have brought many benefits to people. Many of the courses are provided by universities in foreign countries, and thus offer fresh ideas to us. Through them, we can keep up with what people are thinking all over the world. But that can also be a problem. Some of the courses may not be very suitable for Chinese students because of cultural differences and may cause chaos on Chinese campus.
In my opinion, online open course is useful and we should make use of it to broaden our horizons. But we should also remember to have our own thinking and not be brainwashed by improper ideas.
