Liu Xiang Will Resume Training

    Athens Olympic 110m hurdle champion Liu Xiang felt so relieved to return to racetrack after getting out of the great number of social activities.

    Liu arrived in hometown Shanghai Wednesday night and was about to resume① training shortly after.

    "I am so exhausted② from so many social activities, which made me even more tired than training," said the 21-year-old Liu, who wrote a new chapter in China's Olympic history by winning the country's first ever athletics short-distance running title in the men's 110m hurdles in Athens in August.

    "I am happy that I will resume my training soon back in Shanghai," said the Shanghai native. He turned into an instant national hero with the Olympic glory③ and one of the most popular Olympic gold medalists, taking part in scores of celebration activities since he returned to China early September.

    "My regular training has been interrupted for such a long time that I think I can only run at about 13.5 seconds now," said Liu, who clocked a world record-tying time of 12.91 to clinch the title.

    "I would rather forget what I have achieved in the past and try my best to realize a higher goal," he said.

    Liu already missed the Berlin Golden League Series on Sunday and won't be able to catch the IAAF Grand Prix final slated for September 18-19 in Monaco.

He plans on attending an IAAF all-star tournament in Japan at the end of this month.

The Uniqueness of Finger-prints (指纹的唯一性)

    Every human being has a unique① arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.

    The ridge structure on a person's fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original② pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.

    Finger-prints can be made very easily with printer's ink. They can by recorded easily. With special methods, identification③ can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident.

    When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to "develop" them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.
