Dear graduates，

It's time to say goodbye to you all. I am sure all of you have finished what the teachers want you to learn and are ready to start your new life. ______ you want to be a senior high school student or not, I believe what you've learned will be the most unforgettable ______ not only for you but also for me.

As one of the teachers in Grade Nine, I am so ______ and satisfied to keep company with you these years and to watch each of you grow day by day. Every corner in our campus(校园) is ______ with our sweet memories. Every student who entered some competitions always tried his best to ______ the prize for his own class. They practiced again and again even if they got hurt, and they never gave up ______. I hope all of you can take the spirit wherever you are. ______ your dream until you reach the goal.

Besides, use your time well. As everyone knows, “Time and tide wait for no man.” Some things will repeat ______， but others won't. So use every minute well to do some helpful and meaningful things. Don't just fool around all day and then complain, “If I had ______ time, I would do my best to finish that.” Use your time well, and you can be a very successful person in the future.

At last, all I want to tell you is facing every challenge bravely when you are ______ your way to success.
