Hello,
Some of my students use google translate for their homework and are very surprised that I can realize that very quick. Google translate uses the word order of the original language in the to be translated language and there are typical translation mistakes. Moreover names are translated as well. As these translations are as well faulty regarding the grammar, you have to be careful.
Google translations are useful if you do not understand a certain text and want to know what it is about. Still there can be pitfalls: double negations or simple negations are sometimes translated wrong, that would give the text a complete different meaning. I usually tell my students not to use google translations.
Have fun

It is improving a lot. From Portuguese to English, sometimes, it is surprising how it can reorganize the word order, omit some idiomatic words of reinforcement, and so on.

Using google translate as a dictionary is in my eyes not a good idea. There are heaps of nice dictionaries (I have opened a discussion for that).
