If a reader is lost, it is generally because the writer has not been careful enough to keep him on the path. This carelessness can take any number of forms. Perhaps a sentence is so excessively cluttered that the reader, hacking his way through the verbiage, simply doesn't know what it means. Perhaps a sentence has been so shoddily constructed that the reader could read it in any of several ways. Perhaps the writer has switched tenses, or has switched pronouns in mid-sentence, so the reader loses track of when the action took place or who is talking. Perhaps sentence B is not logical sequel to sentence A —— the writer, in whose head the connection is clear, has not bothered to provide the missing link. Perhaps the writer has used an important word incorrectly by not taking the trouble to look it up. He may think that "sanguine" and "sanguinary" mean the same thing, but the difference is a bloody big one. The reader can only infer what the writer is trying to imply.

哒哒英语教的很不错的。主要得从几个方面来说的，第一个是他们的外教老师资质比较高，有教学证书还有教小孩子的多年经验，发音上也很准确。上课时是一对一跟老师视频教的，和老师聊天时是用英语聊的，感觉这种环境能让孩子学得很快的啊。
