I have to finish that report tonight.

I practice the piano every day.

His story made me associate with old memories in my mind.

He went to the gym for five days in a row.

An old person was walking in the park.

He is working all day long.

He is interested in the design of rocket engines.

He spent a lot of time discussing the issue in depth.

They got involved in an argument about politics.

He won the Nobel Prize for that thesis.
