【英语时差8,16】看“聪明宝宝"影片有用吗？（上）

 I’ve heard that so called smart baby videos claiming to enhance language and number skills are pretty much worthless when it comes to actually making babies smarter. But if that’s true, why do so many people buy them? Am I missing something? Good question. And the answer is no, you’re not missing something. Several studies over the past few years have demonstrated that smart baby videos alone aren’t as effective as we’re led to believe. For example, a study testing the benefits of a smart baby language DVD examined its effects on 72 infants. Some watched the DVD with or without a parent. Others did not watch the video and were taught the same 25 words by a parent. And guess what? The infants in the group who learned from their parents without the video did the best.
