   How i can enable structure of file in the left of the texwork window?

I have read some question in this forum but they were not well. Please say me step by step.

Answer 1

This feature (autocompletion) should be the default feature. To ensure it, go to Edit → Preferences. In the editor tab of the window that opens autocompletion (under global editor options) should have been checked like this:

Then read this:

This is available under the help menu - A short manual for TeXworks. All you have to do is type bfig and press TAB to get

\begin{figure}

\end{figure}•

TAB is the key that enables auto completion.
