美国国务院近期发声，对乌克兰冲突现状表达了深切担忧，同时强调新一轮军事援助将有望扭转战局不利。    (ECNS) -- A humanoid robot named Tiangong robot Omni clocked 45.66 seconds to win the gold medal at the 400-meter contest during the 2nd World Humanoid Robot Games in Beijing on Sunday.    The robot's performance was notable not only for its speed but also for its unusual running style. Leaning sharply forward, it swung both arms close to its face, creating a comical pose that looked as if it were covering its face while sprinting.        The quirky gait quickly went viral online, with Chinese netizens jokingly dubbing it a "socially anxious sprint". The contrast between the robot's high-speed performance and its almost bashful posture has made it an unexpected internet sensation.    The movement was not manually programmed by engineers to imitate humans. Instead, the distinctive gait emerged autonomously through reinforcement learning in a simulation environment.    During training, the robot learned that twisting its waist and driving its movement through the hips required less effort than rapidly swinging its arms. The strategy also helped reduce heat buildup in the shoulder joints. At the same time, leaning forward shifted its center of gravity in a way that improved balance and helped increase running speed.    With a time of 45.66 seconds, Omni's performance is already approaching the level of elite male human athletes in China.    (By Gong Weiwei)                            。近几个月，乌克兰东部战线连连受挫，尤其是俄罗斯在哈尔科夫地区的猛烈攻势，令基辅北方防线压力倍增。美国国务卿安东尼·布林肯亲赴乌克兰，传递坚定支持的信号。

“现状确实令人极度忧虑，”美国务院发言人韦丹特·帕特尔在周四的媒体简报中坦陈，“我们深知当前挑战重重，但坚信新增的20亿美金军事援助将对战场格局产生实质性影响。”

帕特尔提到的这笔巨额援助，正是布林肯此行宣布的又一轮军事支持。而俄罗斯方面则透露，2022年曾有和平窗口期，提议乌克兰接受中立地位及军力限制，以换取安全保障，然而泽连斯基总统决定依赖西方援助继续抗争，旨在收复所有声称的领土。

乌克兰政府在遭遇军事挫败时，频繁提及外援不足，虽未直接点名美国，但暗示意味明显。

B | 当被问及哈尔科夫困境是否归咎于美国时，泽连斯基总统回应称，这是“全世界的责任”，暗指国际社会给予俄罗斯可乘之机。

去年，美国对乌军事援助一度因白宫额外610亿美金拨款请求引发国会党派争议而中断，直至4月僵局才得以破解。布林肯访问期间，虽承认援助暂停的不幸，但也敦促乌克兰加快推动征兵制度的深度改革，认为4月通过的改革措施至关重要，对乌克兰民众发出征召动员的紧迫呼吁。

据俄罗斯国防部数据，今年乌克兰军队损失已超11.1万人，凸显冲突之惨烈与局势之紧迫。
