思路點撥
本圖中，一個女孩正在因一個問題感到困惑，「10牛的水是否產生10牛的浮力?」。於是她上網求助於網友，網友的答案更是五花八門，說對說錯的都有。女孩更加困惑。由此可見，這幅圖反應了這樣一個現實：網絡文化有利也有弊。因此本文可以這樣設計：
第一段：描述圖畫;第二段：網絡的利+舉例，網絡的弊+舉例;第三段：提出建議措施——取其精華，去其糟粕。
思路拓展
所有利弊型的文章，均可按照本範文提供的思路進行論述。例如，城市化的利與弊。大學擴招的利與弊等。

Just as what is shown in the picture， a girl is asking a question online. Answers from different netizens differ so greatly that the girl is very confused about whom she should follow①。 It is obvious that it is becoming a fashion for people to ask questions online when confronting a dilemma.
The implication implicit in the drawing can be elaborated as follows. On the one hand， the Internet has provided us with great convenience. For example， we can get knowledge about nearly all aspects on the Internet with only several keyboard commands and a few clicks of the mouse through search engines such as Baidu and so on. On the other hand， with an explosive amount of information on the Internet②， it can be difficult to tell good information from bad③。 For example， teenagers and adolescents may mistake the bad information online as good， the result of which can be rather devastating. Some dirty information on the net may exert negative impacts on people.
In conclusion， on the one hand， it is important for us to take full advantage of Internet to enhance our efficiency and save our time. On the other hand， effective steps should be taken to educate people to avoid and elude inappropriate and even wrong data online so as not to be misguided. Only in this way can the net better serve for our life， study and work④。
