雪上，切莫乐而忘忧

天越冷,雪越大,滑雪发烧友们的热情也越高。此时,保持头脑清醒,做好雪上雪下的各种防护准备是必须的,毕竟滑雪现在被国家体育总局列为四大高危运动项目之一……     

修道院的桥牌亚雷修士的精彩打法

由于每一次都指望轻松拿到一或两个顶分,院长抽出他的第一副牌迎战亚雷修士和他搭档。这是牌局：一次激烈的叫牌让亚雷修士叫上了小满贯。“嗯,真令人激动!”他说。“你真的知道,伙计,我的4红桃是个阻击叫吗？”“在四阶？”迈克尔问。“我以为我们用3红桃作为弱叫牌。”院长首攻他的单张黑桃防守满贯,明手亮牌。亚雷修士对他看到的牌没什么太激动。至少在黑桃套上有2个输张——如果这个首攻是单张就是3个。“9点还不足够叫满贯,”他告诉同伴。“在我做阻击叫时就不行。”     

如何在赛前保持放松和平静

为什么比赛尚未开始,胜负已经决定下来？ 正如我多次强调的,在理应游出最好水平的比赛中表现出类拔萃的最大秘密在于：比赛之前准备上场时,你能够保持放松和平静。太多的运动员在即将比赛之前考虑并且将精力集中于不应当考虑的问题和事情上,浪费了宝贵的精力。由于这一原因,他们有意无意地破坏了自己的信心,使得自己过分紧张,最终导致比赛失败。     

俄罗斯花游队:运动之外无生活

所有的运动部有高手,获奖无数的冠军。然而,在某些时候,哪怕是巨人也会失手．比如,不是所有的奥运会和世锦赛的篮球冠军都由美国获得。但是在花样游泳上,俄罗斯总是夺冠。

蟑螂被斩首后还能活多久

蟑螂被斩首后还能活多久-地球上有3500多种蟑螂。直到不久前,"世界最大蟑螂"纪录的保持者都是澳洲犀牛蟑螂。奇怪的是,这种没翅膀的蟑螂是澳洲人当中流行的宠物。它的体长可以达到9厘米,体重超过44克,和一节5号电池相仿。虽然块头大,这种蟑螂却能把身子压扁、钻进狭小的空间。到了2004年,科学家又在考察婆罗洲的洞穴时发现了一个     

Neuromuscular control and running economy is preserved in elite international triathletes after cycling

Running is the most important discipline for Olympic triathlon success. However, cycling impairs running muscle recruitment and performance in some highly trained triathletes; though it is not known if this occurs in elite international triathletes. The purpose of this study was to investigate the effect of cycling in two different protocols on running economy and neuromuscular control in elite international triathletes. Muscle recruitment and sagittal plane joint angles of the left lower extremity and running economy were compared between control (no preceding cycle) and transition (preceded by cycling) runs for two different cycle protocols (20-minute low-intensity and 50-minute high-intensity cycles) in seven elite international triathletes. Muscle recruitment and joint angles were not different between control and transition runs for either cycle protocols. Running economy was also not different between control and transition runs for the low-intensity (62.4 +/- 4.5 vs. 62.1 +/- 4.0 ml/min/kg, p > 0.05) and high-intensity (63.4 +/- 3.5 vs. 63.3 +/- 4.3 ml/min/kg, p > 0.05) cycle protocols. The results of this study demonstrate that both low- and high-intensity cycles do not adversely influence neuromuscular control and running economy in elite international triathletes.

六个娃娃七个坑

一个大热天,七个小男孩由符兰齐克领头,来到河边。他们在沙滩上修地道、筑碉堡。玩厌了,就扑通扑通往河里一跳。他们在洞里游呀,叫呀,白花花的水沫溅成一片。符兰齐克看了看伙伴,一个个点起数来: “一、二、三……”他点了几遍,都只数出六个来。他着慌地叫开了:“喂!有谁淹进水里了?我们来的时候有七个,可现在只有六个了!”孩子们慌起来,也都点开了数儿。“六个!只有六个!”他们一个跟着一个叫起来。他们有的用树枝在河里捞;有的扎猛子到河里去摸,大叫大     

Perception of suprasegmental features of speech by children with cochlear implants and children with hearing AIDS

This study assessed perception of suprasegmental features of speech by 30 prelingual children with sensorineural hearing loss. Ten children had cochlear implants (CIs), and 20 children wore hearing aids (HA): 10 with severe hearing loss and 10 with profound hearing loss. Perception of intonation, syllable stress, word emphasis, and word pattern was assessed. Results revealed that the two HA groups significantly outperformed the CI group in perceiving both intonation and stress. Within each group, word pattern was perceived best, and then intonation and emphasis, with syllable stress perceived poorest. No significant correlation emerged between age at implantation and perception of the various suprasegmental features, possibly due to participants' relatively late age at implantation. Results indicated that CI use did not show an advantage over HA use in the perception of suprasegmental features of speech. Future research should continue to explore variables that might improve this perception.
