I think there's nothing quite as alarming as somebody just launching into something that means nothing to you.

我认为没有什么比有人突然开始做对你毫无意义的事情更令人震惊的了。

So I've just got to do my best, and take a couple of seconds to look through the first few lines before I launch into something.

所以我只能尽全力做好，在开始之前花几秒钟时间浏览一下前几行。
