Hello handsome Eric!

    Thank you so much for making your homework. I am very happy that most of your created sentence are correct. ^^ Keep improving your skills.  Don't forget as well to do oral reading to practice  your tongue in pronouncing English words. I can see that you are still having a hard time with some sounds.

Take care always and see you next week. HAPPY NEW YEAR to you and to your family, Eric! ^^
