LaTeX: Align multiple align-environments

I would like to align multiple align-environments as e.g.:

\documentclass{minimal}
\usepackage{amsmath}

\begin{document}
\begin{align}开发者_高级运维
wolf &= animal \iff P(wolf)
\end{align}
blah blah
\begin{align}
a &= b
\end{align}
\end{document}

The equal sign of formula (1) and (2) should be aligned with each other, i.e. alignment across several align-environments. Is something like this possible?

Regards, Stefan

One thing you can do is to use only one align environment, with your interspersed text lines enclosed in a \textrm{} command. The only trouble with this is that the text will not wrap.

A better alternative would be to use an \intertext{} command, which handles line breaks without breaking the \align alignment, but again, this is meant for small amounts of text.
