Nelson Mandela turns 91 on the 18th of July, and the call has gone out for people everywhere to celebrate his birthday and the global launch of Mandela Day by acting on the idea that each person has the power to change the world. The call by the Nelson Mandela Foundation and its sister organizations for the creation of an official global Mandela Day is gaining great support. It is to be celebrated on the 18th of July every year－Mandela’s birthday. “The celebration of Mandela Day aims to call on people to recognize their power and devote 67 minutes to making an imprint (印记) and helping change the world around them for the better”, the Nelson Mandela Foundation said at the launch of the campaign in April. “Nelson Mandela has been making an imprint on the world for 67 years, beginning in 1942 when he first started to fight for the human rights of every South African. He has set a good example to the world. ” Mandela said at the time of the launch that he would be honoured if such a day can serve to bring together people around the world to fight poverty and improve peace. Former US president Bill Clinton said Mandela’s example showed that the power of public kindness does not require public office, but a well-placed heart and a determined mind . South African President Jacob Zuma said it would give people in South Africa and all over the world the opportunity to do something good to help others. Let us wholeheartedly support Mandela Day and encourage the world to join us in this wonderful campaign. 51. The underlined word “launch” in the first paragraph can be replaced by“________”.
