　　1.细节理解题。根据第一段中的“We can study and work on it. We can find a job on it. We can communicate on it. We can treat friends on it. We can buy and sell on it.”可知，我们能利用网络学习和工作、找工作以及和朋友聊天、买卖商品等很多事情，但文中没有提到把朋友的信息提供给他人，故选B项。

　　2.代词指代题。根据画线词前的“our information might be open, stolen or sold.”可知，我们的个人信息可能是开放的、被盗或被贩卖，此处是说甚至有时我们的个人信息会被别人免费使用，由此可知it指代的就是我们的个人信息，故C项正确。

　　3.细节理解题。根据第三段中的“First, when you need Internet service, you should always look through those big legal websites. Second, if the service requires important personal information, you should think twice before you type it in. Third, store your own important card key and don’t tell others easily. ”可知，首先，你要浏览那些大的合法的网站，其次，如果网络服务需要你重要的个人信息你要三思而行，再次，保存好自己的电子钥匙，不要轻易告诉他人，故C项正确。
