Free web translators
Foreign language translating engines on the internet
You'll notice that the very best websites (like this one!) provide a free translation tool (in our case, it's at the very upper-right corner of the screen).
Computerized translations are, of course, far from perfect, but you can use them to understand about 80%–90% of what you're trying to read online in a foreign language—and they are free.
