David Beckham

In the world of professional soccer, no star shines brighter than David Beckham. He is one of the best players in the sport, admired by fans around the world. Not only is Beckham an excellent player, but he also happens to have supermodel looks! Girls adore his handsome face and friendly **ile.

As a celebrity, Beckham attracts more attention than most rock stars, including his wife, former Spice Girl Victoria Adams. Fashion magazines have a field day every time he wears a new outfit or gets a new hairstyle.

David Beckham was born in an eastern suburb of London in February 1975. Ever since he can remember, soccer has always been the main focus in his life. That? because not long after he could walk, Beckham? father began playing soccer with him. Each year Beckham's father gave him a Manchester United uniform and a new soccer ball.The two would regularly kick the ball around outside until it was too dark to see

anything. Beckham had lots of natural ability, and constant practice developed his soccer talent.

Beckham rise to the top

By the time Beckham entered his teens, professional scouts were already watching his progress as a standout player. When Beckham turned 16, Manchester United asked him to join the team as a trainee. After training in the youth circuit, 20-year-old Beckham played his first game for Manchester United in April 1995. Over the following seasons, Beckham scored some amazing goals, making him well known throughout the country. Thanks to Beckham, Manchester United won many awards. He performed so well that he was asked to play for England's national team in 1997.

When England played Argentina at the 1998 World Cup, Beckham? image took a blow. He was sent off for kicking at an opponent. But back in England, Beckham took Manchester United to another league victory that season. Beckham was playing the best he played in his whole life, and fans couldn't get enough of him.

Beckham's star rose even higher in July 1999, when he married Victoria Adams of the then-popular Spice Girls singing group. Beckham waselevated to the position of both soccer star and celebrity.

The Beckham lifestyle

Beckham seems to enjoy being in the spotlight. He likes wearing stylish clothes,driving fancy sports cars and experimenting with new hairstyles. Beckham regularly volunteers to pose for fashion magazines, and the press follows his every move.

Beckham's personal life, however, is more down to earth. Given the choice, Beckham says his perfect evening would be a quiet night at home with his wife and their two young sons. Beckham refuses to hire a nanny and puts a high priority on his family time.

In 2002, Asian fans got their first chance to see the famous Beckham up close. England's team gave an impressive performance at the World Cup in Japan. Beckham delighted fans by scoring a goal against rival Argentina. But England was ultimately defeated by champion Brazil and failed to reach the semifinals.

Fans and followers are now waiting to see how Beckham fares in Spain. Manchester United sold their star to Spain? Real Madrid team in the summer of 2003. But regardless of where he plays, Beckham should continue to score goals and turn heads.

冠军杯 World Cup

Kaka Wins 2007 European Footballer of the Year Award

It's been a fantastic season for AC Milan and Brazil's playmaker extraordinaire and the plaudits just keep rolling in with the announcement that Kaka has convincingly won the vote for the 2007 Ballon D'Or as European Footballer of the Year.

Kaka's 444 points saw him well ahead of Manchester United's Portuguese winger Cristiano Ronaldo in second place who scored 277 points and Barcelona's Argentine striker Lionel Messi who finished third.

These three players are also contesting the World Footballer of the Year competition and in all three cases, their inclusion so high up the list of performers on a world and European stage is well deserved.

Kaka became the eighth AC Milan player to win the Ballon D'Or, which is awarded annually by France Football magazine who poll 96 prominent football journalists, and spoke of his personal delight at winning the trophy: "I want to thank everyone," said Kaka. "It's a very special day for me, a very important day for my career and for all the Rossoneri fans.

"The Golden Ball is an individual award and for me this is a dream come true. Today I really feel this recognition to be truly mine."

He added: "Perhaps I have been more decisive than Ronaldo and Messi.

"I faced Ronaldo last season while Messi, I believe he has been penalised for not winning a big competition like the domestic tournament or the Champions League."

King Kaka and Marta crowned(FIFA.com) Monday 17 December 2007

Print Email to a friend Share

2007's top players almost predictably both hail from the beautiful game's spiritual home of Brazil. Kaka topped the men's side while Marta scooped the award for the women.

Ac Milan's Kaka, who just days ago snapped up the Ballon d'Or as Europe's top player for 2007, was again the centre of attention on 17 December at the Zurich Opera House. The wide-**iling, elegant midfielder from Brasilia became the fifth Brazilian to be named FIFA World Player of the Year amid boisterous applause and all-around appreciation.

His exploits in helping Milan win both European and world titles played a big role in seeing the thoroughbred midfielder achieve the ultimate success on a night in which he beat out Lionel Messi of Argentina and Barcelona and fleet-footed Manchester United and Portugal trickster Cristiano Ronaldo.

On the women's side of things, sumptuous Umea striker Marta picked up her second player of the year title in succession. She helped drag an amazing Brazilian side to the final of the FIFA Women's World Cup in China in September and is fast emerging as the shining light of the female game.

Rampaging Marta, predictably overwhelmed by the honour, beat out Birgit Prinz of two-time world champions Germany and her own Brazilian team-mate Cristiane.

In the night's other commendations, Barcelona received the FIFA Fair Play award and 'O Rei' Pele picked up the FIFA Presidential Award.

----------------------------------

Already this year Kaka has won the Ballon d'Or award for the European footballer of the year and FIFPro's world player of the year, voted by fellow professionals.

Kaka has had a great year for AC Milan, helping them to win the Champions League.

The Brazilian playmaker said at the awards ceremony in Zurich: "Tonight is a really special night for me - it was a dream for me just to play for Sao Paulo and one game for Brazil. But the Bible says God can give you more than you even ask for."

This year's shortlist contains three young players nominated for the first time.

Kaka, 25, said: "It shows that this is a new era in football, a new cycle is starting.

"They were great players before, but now the new players are starting to make history."

Cristiano Ronaldo, 22, said he was hugely honoured to be short-listed for the award - which has never been won by a Premier League player.

He added: "I was so pleased when I got nominated. The first thing I did was tell the people closest to me.

"It's a real honour for me to be considered one of the three best players in the world."

The award is voted on by all national team managers and captains.

World Cup: Kaká goes to his left to give Brazil a leg up

By Roger CohenPublished: WEDNESDAY, JUNE 14, 2006

BERLIN: Brazil, five times champion and firm favorite to take home a sixth trophy, entered a charged World Cup arena in the German capital's Olympiastadion and defeated a determined Croatian team, 1-0.

The champions had to withstand a threatening Croatian onslaught in the second half to clinch victory. Only the sure hands of the Brazilian goalkeeper, Dida, who has looked fallible at times, kept Croatia at bay.

It took a moment of brilliance from Kaká, a midfielder who plays for AC Milan, to settle the match. Taking a pass from the veteran Brazilian captain, Cafu, in the 44th minute, he swiveled sharply left past two Croatian players on the edge of the penalty area.

Then, after looking up quickly and without breaking his stride, he fired an unstoppable left-footed drive into the top left corner of the net. The goal was conjured from nothing in the grand tradition of Brazilian artistry.

Brazilian supporters, who had been uncharacteristically silent for most of the first half, erupted and the steeply banked stands were transformed into a pulsing sea of yellow and green.

For much of the match, Brazil looked ordinary. Its star striker, Ronaldo, who has scored 12 World Cup goals, the same number as Pelé, is clearly overweight. He was a study in lumbering immobility until he was taken off in the 69th minute and replaced by his fellow Real Madrid player, Robinho. Whether Ronaldo is fit enough to make any impact on this tournament is now an open question.

Alongside him, Adriano of Inter Milan, was also subdued. With two of the four members of its glittering attacking quartet - Ronaldo, Adriano, Ronaldinho and Kaká - making scant impression, Brazil was a side drained of its customary brio.

But first World Cup games are always tense occasions and the trophy is generally won by teams who peak slowly in the monthlong tournament.

Brazil will be satisfied - and relieved - to have taken three points, putting it at the top of Group F with Australia, the upstart team it will meet next, in Munich on Sunday.

It was a historic setting for the first game by an experienced Brazilian team that knows a sixth triumph would secure its places in the history books by establishing something close to a monopoly on soccer's highest accolade.

Germany has refurbished rather than rebuilt the stadium completed for the 1936 Olympic Games that opened in Nazi Berlin under Hitler's gaze and to a sea of swastikas. Jesse Owens's name, as well as that of Nazi architects, is still engraved in the stone of the Marathon Gate.

This style, an acknowledgment of the past with a look to the future, has characterized Germany post-Cold War return from Bonn to a refashioned capital in Berlin, and it is an unabashed nation unafraid to be patriotic that is hosting a tournament that will culminate at the final in this stadium on July 9.

Croatia, which finished in third place in the 1998 World Cup in France, a remarkable performance that solidified the nationhood it had won seven years earlier, started with a confidence reflecting the fact it had not been beaten in its previous 10 competitive matches.

Its most prolific striker, Dado Prso, was immediately menacing. A defense that conceded only five goals in its 10 qualifying games for the tournament looked tight. Several stray passes from Ronaldinho, the Brazilian midfielder widely regarded as the best player in the world, reflected his team's apparent unease.

Only in the 14th minute did Brazil test Stipe Pletikosa, the Croatian goalkeeper. First, he tipped over a searing drive from the left back Roberto Carlos, who has a shot of legendary power.

Then, from the ensuing corner, he palmed wide a curling shot from Ronaldinho that was heading for the bottom right corner of the goal. Another corner from Ronaldinho produced a crashing half-volley from the onrushing Roberto Carlos that rocketed just over the bar.

But Croatia was not ready to bow to Brazil, the only non-European team to have won the World Cup in Europe, triumphing in Sweden in 1958.

In the 21st minute, Robert Kovac, the team's best defender, almost burst right through, and in the 37th minute, Niko Kovac, a midfielder, just failed to connect with a swerving free kick from left back Darijo Srna in front of an empty net.

Croatia then suffered a double blow: the departure of an injured Niko Kovac in the 40th minute and, four minutes later, Kaká's extravagant, ice-cool display of mark**anship.

Still, the team came storming out for the second half and repeatedly threatened to equalize. Dida had to be at his best to save shots from Prso in the 50th minute and fellow striker Ivan Klasnic three minutes later.

The Brazilian defense, marshaled by Lucio, looked porous. It often needed the fine covering of the defensive midfielder Emerson, who had a tremendous game, to fend off the Croatians.

But Brazil also went close. In the 61st minute, Ronaldinho, whose impact on the game grew as it went on, almost did something he does very rarely - score with a header. He came drifting in to meet Cafu's cross from the right wing, but somehow Pletikosa clawed the ball away at his left side.

A brief and surreal interlude marked the game in the 85th minute when a Croatian supporter somehow made his way onto the field. The Germans, who are not at their best with the unexpected, seemed flummoxed. Nobody moved.

Eventually, a single security guard made his way across the field, and the man was escorted off, leaving Brazil to play out the remaining minutes in relative tranquillity.

It was the end of the game, but only the beginning of a long night of samba in a German capital flooded with Brazilian fans.

二氧化氯发生器如何使用？

我国自八十年代引进国外二氧化氯产品并开始研究其生产工艺以来，经过十几年的时间，不仅有了国产二氧化氯产品，而且生产工艺有了较大的提高，对二氧化氯作为氧化消毒剂的问题出也有了相当的认识和应用。随着产品的广泛应用，促进了产品剂型的发展，目前已有二氧化氯发生器、稳定性二氧化氯、以及片剂等固态二氧化氯产品。现将用于消毒的二氧化氯剂型情况综述如下。

1. 二化氯发生器

1.1二氧化氯的性质和制备

二氧化氯是氯的氧化物，具有与氯气类似的**性气味，分子式ClO2，分子量67．457，熔点-59°C，沸点11°C，在室温下以气体形式存在，为一种黄绿色气体。浓度增加时，颜色变为橙红色，气体二氧化氯极不稳定。二氧化氯易溶于水，在20°C下溶解度为107．98mg/L，可制成不稳定的液体，其液体和气体对温度、压力和光均较敏感，当空气中的含量高于10%时，火花即可引爆[1]，二氧化氯是一种不稳定的化合物，在水中可变成HClO2和HClO3．，在室温下每天约有2-10%的离解率[2]，因此不利于大批量制备和运输，一般多在使用场所现用现制备。

二氧化氯发生器制备二氧化氯的方法主要有电解法和化学法，电解法使用广泛的是隔膜电解法，以食盐为原料，在电场的作用下生成含有二氧化氯，次氯酸钠、双氧水、臭氧的混合溶液，二氧化氯的浓度一般仅为10-30%左右，大多为氯气。化学法主要有以氯酸钠和亚氯酸钠为原料的两类发生二氧化氯的方法。在氯酸钠法生产二氧化氯过程中，若用氯离子作还原剂，则制得的二氧化氯存在纯度低的缺点，而亚氯酸钠法制得的二氧化氯比例高，一般在90%以上。

1.2设备和杀菌性能

国外引进的发生器主要有Tetraralent公司、Rio Lindo公司、德国的Prominent等，李玲文等[3]报道了Tetraralent公司的二氧化氯协同消毒器的协同杀菌作用，该发生器利用电解食盐溶液，同时产生二氧化氯、氯气、臭氧和双氧水，溶于水中，协同杀菌，其杀菌效果优于上述任何一种消毒剂，实验结果还说明，电解槽的电解电压、电流、电解质浓度及阳极有效面积对消毒器的产气量都有影响。宦彭成等[4]对美国Vulcan Rio Linda T140二氧化氯发生器作了消毒效果观察，发生器发生的二氧化氯浓度可调节在2000-300mg /L，杀灭大肠杆菌、金黄色葡萄球菌1mg/L 3分钟，杀灭枯草杆菌黑色变种芽孢125mg/L 5分钟，破坏HBsAg 125mg/L 2分钟，能量实验的最低浓度为400 mg/L，25%与50%小牛血清保护菌液，则可影响杀菌效果，发生器在低浓度时（10mg/L），对铜片、碳钢片、铝片呈轻度腐蚀，对不锈钢片基本不腐蚀。

国内二氧化氯发生器发展较快，工艺逐渐成熟[5]。目前已有用通过电解食盐产生二氧化氯以及用氯酸钠和亚氯酸钠法生产的正压式和负压式二氧化氯发生器，其中有些产品已获国家专利。任庆伟[6]根据电解法制备二氧化氯混合消毒液的工作原理和运行特性，采用单片机技术和余氯检测器，实现了对二氧化氯消毒设备的加盐、排碱及运行调节等全过程的自动控制，大大提高了消毒效率和设备的安全运地。用化学法生产二氧化氯的含量较高，施来顺等[7]研制的化学法产生二氧化氯的发生器，经碘量法对发生器制备二氧化氯复合消毒液测定，有效氯含量为3246．1 mg/L。用紫外分光光度计与红外分光光度计检测，溶液中含二氧化氯和氯，其中二氧化氯占60%-70%，该水溶液对微生物的杀灭效果表明，含4．5-5．0 mg/L有效成份对水中金黄色葡萄球菌、大肠杆菌与白色念珠菌作用1-2分钟，以含90 mg/L有效成份枯草杆菌黑色变种芽孢作用5分钟，杀灭率均达99．9%以上。以含400 mg/L有效成份作用5分钟可将HBsAg抗原性破坏。二氧化氯发生器的二氧化氯消毒剂性能较不稳定[8]，存放3天，其降解率为14．05%，而如将消毒液原液加分析纯氢氧化钠，将PH值调至11．80，密闭避光，室温存放（18°C-25°C）18个月，降解率仅为3．31%。

1.3在消毒上的应用

目前二氧化氯发生器主要用于对饮用水消毒和污水处理等，传统饮用水消毒使用的氯消毒剂在处理原水时会有大量的卤代烃产生，包括三卤甲烷如氯仿以及氯代酚和二氯乙腈等有
