  土外长本周或与俄罗斯签订S-400系统购买协议

  百度哈登继续肆虐连中3球连砍7分,但开拓者秉持多点开花的原则,继续巩固48-45的微弱领先优势。双方先发:马刺:安德森、格林、穆雷、阿德、米尔斯勇士:尼克杨、帕楚利亚、库克、伊格达拉、格林(上官正)

他写道,就像我曾经说过的,我不说话,只用行动证明。据悉,灰熊主教练比斯科塔夫和核心巨星小加索尔,当时都不在更衣室里。

  虽然奇才替补疯狂砍分,可惜无济于事。北京时间3月6日晚,亚冠小组赛G组一场焦点战,广州恒大在主场迎战济州联,目前双方已经公布了本场比赛的首发阵容。

  活塞暂停回来,史密斯反击一条龙得手,乔-约翰逊转身上篮2加1,格里芬篮下强打还击,两边比分交替上涨。而麦蒂的这次也将成为第七位入选魔术名人堂的成员,前六位分别是帕特-威廉姆斯、吉米-休伊特、查德-德沃斯、尼克-安德森、沙奎尔-奥尼尔和安芬尼-哈达威。

也许是汤神太容易被模仿了吧?总之我们都知道,这两名不法分子都不是汤普森本人,用汤神自己的话来说:这完全没必要啊!

  北京时间3月24日上午,NBA常规赛继续进行,勇士坐镇主场迎战老鹰。

  当然的确还有地方可以提高,职业体育里没有满足,永远都能提高。除此之外,魔兽最后阶段还罚进制胜两球,在场正负值高达+16成为黄蜂逆转篮网的头号功臣。

  本轮赛前,恒大落后济州联队1分,落后大阪樱花2分,此役对阵G组第二的济州联队,如果此役恒大取胜,将有机会登顶G组。

  一旦伦纳德能够回归,无疑重组双德核心的马刺有望扮演西部超级黑马。尽管这可能导致勇士队在季后赛没有主场优势,但一向擅长打季后赛的勇士队,季后赛才是真正的主战场,届时的他们即便没有主场优势,也不会惧怕任何对手,这才是他们最恐怖的地方。

  他们尽自己最大的能力给予辽篮支持,帮助年轻的辽篮迅速崛起,很快回归CBA强队之林,并从2014-2015赛季开始迎来了队史又一个高峰期,成为具备争冠实力的联盟一流强队。

  百度当时弗朗西斯意识不清楚,还出言不逊,兄弟,如果你碰了那条项链,你就得跟人(上级)好好谈谈了。

  雷霆这边,安东尼翻身跳投打成2+1,亚当斯两罚全进,威斯布鲁克举火烧天暴扣得手,客队继续维持领先优势。本场比赛,两队激战四节,勇士最终在主场以106-94逆转老鹰。

Editor's note: During the just-concluded May Day holiday, "glass paths" became the new buzzword in the tourism sector. Two experts share their views with China Daily's Zhang Zhouxiang on the mushrooming of glass-bottomed walkways over gorges in scenic spots across China.

Are the 'glass paths' worth the trouble?

Glass-bottomed bridges were first built between two cliffs so that people could enjoy the scenery around while being aware of the scary depth of the ravine below. For example, in Baishi Mountain Geological National Park in Baoding, North China's Hebei province, a 95-meter-long, 2-meter-wide glass-bottomed walkway was built at an average altitude of 1,900 meters to allow visitors to experience the beautiful but stomach-churning scenery below.

The problem is that glass-bottomed walkways have mushroomed across China. Search glass-bottomed walkways on domestic tourism website tuniu.com, and you will find that 24 cities have built such "glass paths" as their tourist sites. And since a majority of the "glass paths" have been built across valleys bereft of natural beauty, one cannot but question the wisdom to build them.

The rush to build "glass paths" shows the officials in the domestic tourist sites lack creativity. Instead of using the inherent advantages of the tourist sites, they are busy copying ideas and examples from others. Such homogenization fails to meet tourists' diversified demands.

More importantly, the glass needed for the glass-bottomed walkways is expensive and the total cost of such a bridge can run into several million yuan, and some tourist sites may fail to earn enough revenue to cover the expenses, let alone make profits, which would be a waste of tourism resources. And any compromise with the quality of the glass or the overall glass-bottomed bridge could spell trouble.

Liu Simin, vice-president of tourism at Beijing-based Chinese Society for Future Studies

Such bridges need total safety system

No major accidents have been reported from glass-bottomed walkways. And many tourism sites claim double-or multi-layered armored glass, which is three to four times stronger than ordinary glass, have been used to build such walkways.

But good safety records do not necessarily guarantee safety in the future. There is a national standard for the glass used in outer parts of structures (as a curtain wall for a building for example) but no special standard for the glass used in glass-bottomed walkways. I do not mean to raise unnecessary alarm, but without a national standard no one can ensure safety forever on the "glass paths".

Besides, people tend to equal the risk with glass-bottomed bridges to the cracking of glass and people falling into the ravines. But that is not the only risk.

On April 9, the overcrowding on a glass-bottomed bridge in Mulanshengtian tourism zone in Wuhan, Central China's Hubei province, amidst heavy rainfall caused an accident in which one person died and three were injured. The incident should be a lesson for us. Regular safety checks must be conducted to test the strength and durability of such walkways, while the maintenance and supervision staff should be fully trained to know under what conditions the walkways should be closed and how to deal with emergencies.

Besides, not everybody is fit to walk on such "glass paths", because looking down into a deep ravine might raise a person's blood pressure, increasing the risk of a heart attack. In fact, several reports have said tourists started crying out in fear on such walkways. The tourist sites with such walkways should therefore display clear safety instructions so that visitors know the risks and people with unfavorable health conditions stay away from them.

Only a comprehensive safety system can ensure tourists' safety on glass-bottomed bridges.

Gong Jian, an associate professor at Wuhan Branch of China Tourism Academy
