Step 7 Language points

1. I learned about the inventions that led to color movies, too. 我还了解了一些发明，它们成就了彩色电影。

此处learn是"了解；获知；得知"的意思，由介词about或of引入所获知的具体内容。例如：

The children were all shocked to learn of the death of their headmaster.

得知校长去世，孩子们都十分震惊。

I only learned about the accident later. 我只是后来才得知了事故的情况。

2. I've never been camping. 我从未野营过。

　　此句为现在完成进行时。这一时态的结构为"have been + 现在分词"，表示从过去某一时刻延续至今的动作。在本句中，说话人使用这一时态来强调自己至今从未有过野营的经历，欠缺这方面的经验。又如：

He's been watching TV all afternoon. 他一下午都在看电视。

We've been living like this ever since the birth of my little brother. 自打我小弟弟出生，我们就一直这样生活。
