(began) 开始 e.g. I’ll begin whenever you’re ready.你什么时候准备好我就开始。 常用的句型：begin to do与begin doing 一般来说，begin to do和begin doing可以互换，但在以下三种情况下，用to do。 (1)主语不是指人，而是it等。 e.g. It began to rain. (2)begin后接表示心理活动的词。e.g. begin to know, 还有believe, wonder, think等词。 (3)begin本身是ing形式，为避免重复后接to do。 e.g. beginning to do 2.
