在教室里批改试卷的数学老师

A realistic classroom photo of a middle-aged male math teacher seated at a wooden desk, grading student papers with his right hand while leaning slightly forward. He has wavy dark brown hair, light skin, and wears a muted blue crew-neck sweater over a checked collared shirt. The face is obscured by a large centered rectangular blur block. On the desk are 2 tall stacks of paper and folders, one on the left and one on the right, an open exam sheet in front of him, 3 loose pens in the foreground in blue, red, and transparent blue, 1 black zip pencil case at the front left, and 1 small black round cap or lid near the center-right of the desk. Behind him is a large dark green chalkboard filled with handwritten French mathematics notes and formulas in white chalk, including a function definition, a square root expression, a list of 5 numbered tasks, and limit notation. The room has soft natural indoor lighting, shallow depth of field, and a documentary-style academic atmosphere. Composition is landscape, medium shot, teacher centered, desk in the foreground, chalkboard spanning the entire background, highly realistic photography.

一张写实的教室照片，一名中年男性数学老师坐在木质书桌前，身体微微前倾，右手正在批改学生试卷。他留着深棕色波浪卷发，肤色白皙，身穿一件柔和的蓝色圆领毛衣，内搭格子衬衫。面部被一个居中的大号矩形模糊遮挡。桌上有两叠高高的试卷和文件夹，分别位于左右两侧；他面前放着一张摊开的试卷；前景处有 3 支散落的笔，分别为蓝色、红色和透明蓝色；左前方有一个黑色拉链笔袋；桌子中右侧附近有一个黑色小圆盖。他身后是一块巨大的深绿色黑板，上面写满了白色的法文数学笔记和公式，包括函数定义、平方根表达式、一个包含 5 项任务的列表以及极限符号。室内光线柔和自然，景深较浅，呈现出纪录片风格的学术氛围。构图为横向中景，老师居中，书桌位于前景，黑板横跨整个背景，具有高度写实的摄影质感。
