2. 然而，接通电话后，我被她"不小心"说出的几句脏 话震惊了。

However, I was astonished by dirty wods which she said unconciously after the telephone line is through.

A: However, after calling, I was astonished by a few dirty words that she said "carelessly".

B: However, when I got her on the phone, I was shocked by a few dirty words that she spoke "carelessly".

解析:

1. A句中的"after calling"(打电话之后)的问题和第一句中的"connect with"一样，强调的是打电话的动作，而不能体现出原文中"电话已接通"这样一种的状态。

2. "astonished"和"shocked"都表示"惊讶"，但是"astonished"一般表示一种正面意义"惊讶"，而"shocked"更多的是负面的"震惊"，更符合上下文。

3. "said"和"spoke"用在这里都可以表意，但B句选择了"spoke"，因为结合上下文来看， "spoke"比泛泛的"said"更加尖锐，更能强调那种"脏话脱口而出"的戏剧性效果。
