Welcome to our school! I’m honored to give you a brief introduction about the optional courses for Grade 1 students in our school. In total, there are 50 optional courses for us to choose from, including Advanced science, Music Appreciation, Western Art, etc. Every term, each student can select two courses after applying online first. Every Monday and Tuesday afternoon, we will go to different classrooms to attend the optional courses. The course that I’m going to take today is my favorite, Music Appreciation, which provides us with 90 minutes of enjoyment. Thanks to the optional courses, we have the opportunities to learn what we are really interested in outside the regular classes.
Now, please follow me into my classroom.
