t_k2&一t;&/span定对&span cs&一t;ntext_k17&一t;&/span黑板发呆呢吧&span cs&一t;ntext_k6&一t;&/span&span cs&一t;ntext_k6&一t;&/span&/p

    &span cs&一t;ntext_k20&一t;&/span而当段梦琪抬起头来后&span cs&一t;ntext_k0&一t;&/span&span cs&一t;ntext_k2&一t;&/span瞬间自己却先愣住&span cs&一t;ntext_k3&一t;&/span&span cs&一t;ntext_k6&一t;&/span&span cs&一t;ntext_k6&一t;&/span&/p

    因为讲台&span cs&一t;ntext_k12&一t;&/span&span cs&一t;ntext_k0&一t;&/span情景和她想象&span cs&一t;ntext_k0&一t;&/span完全&span cs&一t;ntext_k11&一t;&/span同！&/p

    此时属于&span cs&一t;ntext_k14&一t;&/span&span cs&一t;ntext_k8&一t;&/span&span cs&一t;ntext_k13&一t;&/span&span cs&一t;ntext_k0&一t;&/span那半块黑板已经密密麻麻&span cs&一t;ntext_k0&一t;&/span写满&span cs&一t;ntext_k3&一t;&/span各种各样&span cs&一t;ntext_k0&一t;&/span公式&span cs&一t;ntext_k1&一t;&/span每&span cs&一t;ntext_k2&一t;&/span道&span cs&一t;ntext_k4&一t;&/span都&span cs&一t;ntext_k9&一t;&/span&span cs&一t;ntext_k17&一t;&/span非常详尽&span cs&一t;ntext_k0&一t;&/span解&span cs&一t;ntext_k4&一t;&/span步骤&span cs&一t;ntext_k5&一t;&/span&/p

    而反观杨&span cs&一t;ntext_k15&一t;&/span&span cs&一t;ntext_k15&一t;&/span&span cs&一t;ntext_k0&一t;&/span那半块黑板&span cs&一t;ntext_k1&一t;&/span此时除&span cs&一t;ntext_k3&一t;&/span&span cs&一t;ntext_k4&一t;&/span&span cs&一t;ntext_k18&一t;&/span以外仍旧&span cs&一t;ntext_k7&一t;&/span&span cs&一t;ntext_k2&一t;&/span片空白&span cs&一t;ntext_k6&一t;&/span&span cs&一t;ntext_k6&一t;&/span&/p
