a站被罚12万元

当地时间7月25日中午11点07分，中国男足选拔队抵达日本爱知县丰田公园体育场进行东亚杯第二轮中、日比赛后的身体恢复训练。与以往训练前三言两句作叮嘱不同，主教练扬科维奇在本次训练开始前进行了足足5分钟讲话。针对球队逼平日本队后获得的外界肯定甚至赞誉，扬科维奇善意提醒弟子们说，“不要过多关注网上评论，那些评价可能比你们实际表现要好，希望你们保持谦卑，争取下一场赢下对手。” 在当地时间24日晚丰田体育场进行的东亚杯第二轮角逐中，中国男足选拔队凭借毅力与勇气以0比0逼和日本队。         Photo: Screenshot from peerj.com
Chinese scientists studying a 244-million-year-old ichthyosaur Mixosaurus fossil from Southwest China’s Guizhou Province found at least 11 embryos inside the specimen. The discovery sets a new record for the highest number of embryos found in ichthyosaur lineages and reveals that high reproductive capacity in ichthyosaurs emerged earlier than previously believed, chinanews.com reported on Wednesday. 
Ichthyosaur was among the most successful Mesozoic marine reptiles, and its reproductive strategy was considered crucial to their adaptation to ocean environments. Its reproductive ability before extinction has long intrigued paleontologists.
A joint research team from the Institute of Vertebrate Paleontology and Paleoanthropology, Chinese Academy of Sciences (CAS), and the Zhejiang Museum of Natural History, has published the study on the ichthyosaur paleontology in the international journal PeerJ. 
According to Wang Wei, the paper’s corresponding author and an associate professor at the institute, embryo-preserving ichthyosaur fossils have been found across 11 genera from the Early Triassic to the Early Cretaceous. 
However, for ichthyosaur groups that diverged in the Early Triassic, embryo-bearing fossils known to scientists remain scarce, and knowledge about the number of offspring they carried is especially limited. Previous discoveries of pregnant specimens, such as Chaohusaurus and Mixosaurus, contained no more than three embryos, suggesting limited early reproductive capacity among early ichthyosaurs.
According to Gu Shengxiao, the paper’s first author and a researcher at the Zhejiang Museum of Natural History, the study examined an almost complete adult Mixosaurus panxianensis fossil from Guizhou’s Middle Triassic strata, dating back about 244 million years. The specimen measures 112 centimeters long, including a skull length of 22 centimeters, with only the tail tip missing. 
The researchers identified 11 fetal ichthyosaur skeletons with skulls inside the adult specimen’s abdomen, confirming they were embryos rather than cannibalized prey based on their position and morphology. There are also fossil pieces outside the belly of the adult, which could belong to the 11 or represent other embryos. 
All embryos in the Mixosaurus panxianensis fossil were at a similar late developmental stage, suggesting the mother died shortly before giving birth, according to the researchers.
The Mixosaurus panxianensis fossil containing at least 11 embryos sets a record for Triassic ichthyosaurs and all known ichthyosaur species. The researchers believe this indicates that Mixosaurus may have adopted a reproductive strategy of producing large numbers of offspring in a single birth. This exceptionally high reproductive capacity may have provided them with a survival advantage. 
Among Triassic ichthyosaurs and all known ichthyosaur groups, Mixosaurus is the genus with the largest number of fossil specimens and is also one of the most widely distributed ichthyosaurs. 
The researchers said the multi-embryo Mixosaurus panxianensis fossil may represent an extreme case, but it confirms the species’ ability to produce large numbers of offspring, potentially contributing to its dominance among contemporaneous marine reptiles. 
The study offers the first fossil evidence of high fertility in Triassic ichthyosaurs. Future research will examine other embryo-bearing Triassic ichthyosaurs to determine whether a multiple-offspring reproductive strategy was common in early ichthyosaur evolution and what factors drove this trait, Wang said.

B | 在国足连续4次无缘跻身世界杯正赛的背景下，这场平局十分难得，也鼓舞了中国男子足球队。

按照惯例，扬科维奇会在训练开始前对弟子们作简单的提示。不过本次训练开始前，他却足足“聊”了5分钟。

C | 对于本场训练安排在中、日赛后第二天的上午，扬科维奇解释说：“因为我们第三轮比赛安排在2天后，赛前训练会安排在明天下午。

D | 如果我们今天留在酒店，就意味着将近48小时没有进行有球训练，这非常不利于大家肌肉恢复和血液循环。我知道现在天气炎热，但希望大家咬牙坚持，为了最后的胜利。” 对于前一晚的中、日比赛，扬科维奇坦言：“首先，你们（队员们）踢出了自己的气势，也很好地完成了教练提出的技战术要求。但这项赛事还没有结束，最后一轮的比赛对我们来说更为重要，因为我们需要在比赛中争取进球从而获得胜利。

E | ” 结合外界对国足选拔队在中、日比赛中顽强表现的褒扬，扬科维奇提醒弟子们说：“我想说的是，他们的评价可能比你们实际表现更好。我们还有2天备战时间，只有坚持到裁判员吹响最后一场比赛的结束哨音，你们才可以放松下来。所以现在你们需要保持谦卑的态度。” 也正是因为前一晚刚刚经历了一场消耗巨大的比赛，国足选拔队25日的训练强度并不大，全场训练仅持续不足1小时，且具体内容不涉及技战术安排。训练期间，教练组还安排了诸如“双人夹球跑”等趣味训练内容。

F | 扬科维奇告诉队员们说，“对于最后一场比赛，我们会正常备战。你们无须考虑对手，只要恢复好身体，然后全身心投入到训练中。记住，最后一场比赛非常重要，争取赢下来，然后享受假期。” 对手 最后一轮中国香港队主教练有“想法” 在东亚杯第二轮角逐中，中国男足选拔队以0比0逼平东道主球队日本队，场内发生的一切被坐在现场看台上的中国香港队主教练安德森尽收眼底。尽管中国香港队在此前两轮比赛中分别以0比6、0比3不敌日本队、韩国队。

G | 但在比赛中，中国香港队打出了一定的技战术内容，而中国男足选拔队次轮力保城门不失的表现实际也给了安德森相当的启示。中国香港队自然也希望能够在末轮与中国男足选拔队的比赛中终止不进球的尴尬，甚至争取更理想的战绩。

H | 算上本届赛事，中国香港队已经先后4次参加东亚杯赛(东亚四强赛)，但成绩不如人意。在本届东亚杯次轮不敌韩国队后，中国香港队在东亚杯赛场上已遭遇11连败。

I | 在2003年首届东亚杯赛期间，中国香港队曾以1比3不敌中国队，而当场比赛的进球是中国香港队迄今为止在东亚杯赛场上打入的唯一一粒入球。由于对阵日、韩两队的比赛已经结束，且净吞9弹，中国香港队破东亚杯进球荒的希望落在了27日与中国男足选拔队的末轮比赛上。在与日本队、韩国队交手过程中，中国香港队并没有主动龟缩防守，而是适时主动出击。

J | 对此安德森解释说，“与排名领先我们几十个身位的强队交锋，死守并不能避免失球。因此我们采取了高位逼压的战术，哪怕丢球，也要争取进球，比起取胜，目前球队如果能够取得面貌的改观，取得进步，才更有价值。

K | ” 中国男足选拔队逼和日本队的表现某种程度上也给予中国香港队以巨大的启示和鼓励。安德森对于率队在与中国男足选拔队比赛中取得“突破”，已有想法。本组文/本报记者 肖赧 供图/新华社
