beginning是begin的名词形式，“开头，开端”

When did you start / begin learning (或to learn) English? 你什么时候开始学英语的?
If Mary doesn't come soon, let's start / begin without her. 要是玛丽一会儿不来,咱们就开始,不等她了。
His illness started / began with a slight cough. 他的病是从轻微的咳嗽开始的。

He is just starting / beginning to write the letter. 他刚刚开始写那封信。
② 当物作主语时。如:
The leaves start/ begin to come out when spring comes. 春天到来时,树叶开始长了出来。
