Hello, Nesma-- and welcome to English-test.net.

Yes, you are welcome to present short writing passages for correction and assessment. Judging from the level of your English, I presume you are working in some specialized field in which you are studying 'connectors' and 'transition signals'. I don't know what field those appear in.
