I'm writing a report in japanese. And I want to change the subject a bit, but I don't know what words to use to connect paragraphs but without being sudden.

Please look at the following list of words. Do you know any site where I can study more from? I don't know the term neither in english nor in japanese so I can't really search.

ところが
そこで
それでは
つまり
したがって

Thanks in advance!

(I'll edit the title as soon as I know the exact term)

It's kind of hard to give specific answers since the question isn't very specific, but if you search for 接続詞 I'm sure you can find some info about them.

yes, that's it 接続詞. thanks!

here's a link with quite a few
