还是因为我敢开口唱所以心情长。

Because I have dared to open my mouth to sing at all.

只要开口唱，直到梦想延长，听到回音多嘹亮。

So long as opens the mouth to sing, lengthens until the dream, hears the echo to be resonant.

适当的时候表扬唱得好的同学，鼓励不开口唱的同学。

I encourage the students to sing and praise the students for their nice singing in the proper time.
