原文

Nowadays, the Internet has become an inseparable part of our daily lives. It is used for communicating with friends, searching for informations, and even shopping online. Although it brings many convenience to us, it also has its drawbacks. Firstly, spending too much time on the internet can leads to addiction, which is harmful to our health and social life. Secondly, the vast amount of information on the Internet can make it difficult for people to distinguish true from false. Last but not least, the privacy of individuals is easily violated when they share personal information on the web.

如今，互联网已成为我们日常生活中不可分割的一部分。我们用它与朋友交流、搜索信息，甚至在网上购物。虽然它给我们带来了很多便利，但也有其弊端。首先，上网时间过长会导致成瘾，对我们的健康和社交生活有害。其次，互联网上的海量信息会让人真假难辨。最后但并非最不重要的一点是，当个人在网上分享个人信息时，其隐私很容易遭到泄露。

答案解析

错误1: informations - information
更正: It is used for communicating with friends, searching for information, and even shopping online.
解析: “Information”是不可数名词，不能用复数形式。

错误2: convenience - conveniences
更正: Although it brings us many conveniences, it also has its drawbacks.
解析: 当“convenience”表示多件便利的事物时，应使用复数形式“conveniences”。

错误3: can leads - can lead
更正: Firstly, spending too much time on the internet can lead to addiction, which is harmful to our health and social life.
解析: 情态动词“can”后应接动词原形。

错误4: true from false - true from false ones
更正: Secondly, the vast amount of information on the Internet can make it difficult for people to distinguish true from false ones.
解析: “True”和“false”是形容词，不能直接作“distinguish”的宾语，需要添加名词化成分“ones”来指代前面的“information”。

错误5: Last but not least - Lastly
更正: Lastly, the privacy of individuals is easily violated when they share personal information on the web.
解析: “Last but not least”常用于列举的最后一项，但在这里使用“Lastly”更为自然，表示总结性的最后一点。

错误6: when they share - when sharing
更正: Lastly, the privacy of individuals is easily violated when sharing personal information on the web.
解析: 使用现在分词短语“when sharing”作为时间状语，使句子更加简洁流畅。
