I am doing a research on the lion and need a nice conclusion.please donot give links because i searched all the links and giving me a conclusion...

For a conclusion for your research, you should write about what you learned about the lion, while doing your research. Just make the parts shorter. If you learned a lot about where lions live, and talked about it in a lot of detail in your paper, you would summarize that in a sentence or two. Something like, "Although lions used to live (wherever they used to), they now only live in (whatever area they live in now). "Their diet mostly consists of.....(whatever animals they eat.) You can even start your conclusion with "I learned a lot about lions while doing this research"--if you are allowed to use the word "I" in your paper. Sometimes, if you are writing a formal research paper, you are not supposed to refer to yourself.

In English, we would say , "I am doing research on lions", or on "the" lion; I know those things are difficult when you are ESL.

That is really the most help we can give...we can't just write the whole conclusion for you, but I hope this gives you enough to help you do it.  Good luck!
