I did my best for the exam.

He always keeps a smile on his face.

He reads the newspaper every day to keep up with the latest information.

He is highly regarded in the business industry.

We always strive for the best results.

He is leaning forward to work on the new project.

He exhausted all his strength to finish the job.

He exhausted himself by working to the limit.

He is my best friend.
