Something about italki 关于italki的一些东西 I am a mechanical engineer.This is my fist time to writ something in italki. 我是一个机械工程师，这是我第一次在italki上写东西。 I just browsed some items and comments.I found that some comments which just shows a new sentence 我刚刚看了一些文章和评论，我发现有些评论只有一个新的句子并为附上解释说名可能会让外语学习者更加迷惑. without explain will confuse language learners. For sometimes the sentences written by language learners is current but just not idiomatic,if no explain,they will not know right or wrong. 因为一些外语学习者写的句子是对的，只是不地道而已，如果没有解释，他们就不知道对的还是错的。 So i have some suggestion: 所以我建议： 1. Write sentences and give comments using two languages. 使用两种语言写短文和给评论 2.No explain , no comment. 评论必附解释 Why we need to learn a foreign language? I thought a lot,The most fundamental must be that we want to know some different, 为什么我们需要学一门外语，对此，我想了很多，最根本的原因一定是想要知道一些不一样的东西 we want to communicate to each other.we want to know each other. 我们想要彼此交流，想要理解彼此 so don't care about if it‘s idiomatic,need care if it is understood. 所以别在意是否地道，你需要关系是否能被理解。 Most of the time, we can understand the mean the writer want to express. 大多是时候，我们可以理解作者想要表达的意思 Then just say "Good job！“ or ”You are right，and i have a better one for you reference, 那么就告诉他“好样的” 或者“你是对的，但是我有一个更好的给你参考。 of course you should point out the mistake in principle if they had. 当然，如果有原则性的错误，还是要指出来的。
