Teacher Lin's lecture is very attractive, and we are happy to attend her class. However, more importantly, she has a selfless heart, and she has devoted all her love and selflessness to us. I remember once, we had a composition class, and the topic of that class was what to do during the summer vacation. Teacher Lin asked the students to speak first and then write. Some students didn't speak well in some places, so Mr. Lin took pains to help them correct them. Looking at the composition corrected with red pen, we are all very grateful to Teacher Lin. We should know that teachers often use their spare time to work late into the night when correcting our compositions, and there is no room for entertainment. I think Miss Lin is really a good teacher. She is like a candle, illuminating others and burning herself.
