老张同志是我们的语文老师，兼班主任。因为他平时很平易近人，同学们都很喜欢他，背地里都亲切叫他“老张同志”。他虽然三十出头，但对教育事业有火一般的热情。他的个子很高，走路也十分沉稳，真的有一种班老大的威严，但他从不对同学们凶。老张同志的视力不佳，一副茶色小眼镜从未离眼。最令人佩服的，还是老张的尊口，平时见其紧闭，不苟言笑，一打开便不可收，妙语连珠。我每次看到老张同志。 Comrade Lao Zhang is our language teacher and head teacher. Because he is usually very approachable, his classmates like him very much. They all call him “Comrade Zhang”. Although he is in his early thirties, he has a passion for education. He is very tall and walks very calm. There really is a majesty of the class leader, but he is never fierce to his classmates. Comrade Lao Zhang’s eyesight was poor. A small pair of brown glasses never left his eyes. The most admirable one is Lao Zhang’s esteemed mouth. Usually, he sees it tightly closed and stern. When it is opened, it cannot be closed. Every time I see Comrade Zhang.
