information and social support. There is even a term used to describe the overuse of sharing too much information about kids on social media: "sharenting". Research also finds that "sharenting" isn't going anywhere anytime soon. What's troublesome is that a typical parent has about 150 Facebook friends and only a third of them are actual friends. So that brings up good questions - Who are we really sharing our information with and why? Who knows when and where that photo could resurface in the future?

　　While there's no reliable information on how young children feel about things posted online, we do have information about how teens feel. According to a report by the Family Online Safety Institute, 76% of teens are concerned about their privacy. Many teens constantly search for new apps that allow anonymity. When names are required, they use screen names that don't reveal real information. If our teens are doing a better job of protecting themselves online, shouldn't parents take the lead and do the same? Plus, with more and more college admission representatives and potential employers surfing the internet for potential candidates, we'd hate for one of our posts to change an important decision. Think about it ... online reputations are now becoming inseparable with real life ones.

　　Of course, we can secure our privacy settings, only allowing our friends to view pictures, posts and videos, but that doesn't stop others from uploading our pictures. Adults need to be cautious of sharing information online, especially information about children.

　　So, this holiday season, enjoy family time and share those special memories with family and friends. Before clicking the app to upload photos or videos, stop and think twice.

　　No student of a foreign language needs to be told that grammar is complex. By changing the order of the words and by adding a range of auxiliary verbs (助动词) and suffixes (后缀), we can turn a statement into a question, state whether an action has taken place or is soon to take place, and perform many other word tricks to convey different meanings. However, the question which many language experts can't understand and explain is-who created grammar?

Some recent languages evolved due to the Atlantic slave trade. Since the slaves didn't know each other's languages, they developed a make-shift language called a pidgin. Pidgins are strings of words copied from the language of the landowners. They have little in the way of grammar, and speakers need to use too many words to make their meaning understood. Interestingly, however, all it takes for a pidgin to become a complex language is for a group of children to be exposed to it at the time when they learn their mother tongue. Slave children didn't simply copy the strings of
