Do you know how the Nobel Prize winners are chosen? The Nobel Committees (委员会) send invitations to hundreds of scientists and scholars around the world, asking them to suggest names for the Nobel prizes in the coming year. The names are sent in by February 1. 　　Each committee, with the help of specially invited experts discusses the names suggested, makes out a short list and a vote (表决) is taken for the final choice. The names of the prize winners are announced in October or November. Many famous people from all over the world have been given Nobel Prize for their achievements (成就). 　　The prizes are given on December 10. The Peace Prize is given at Oslo University, the others at a ceremony (典礼) in Stockholm. The King of Sweden gives a diploma (证书), a medal and a cheque to each prize winner. Each Nobel prize winner is expected to give a “Nobel lecture.” 　　Often a prize is given to just one person, but not always. Sometimes a prize is shared. It may be given to two or more people who have worked together. It is also sometimes true that a prize is not given at all. In 1972, for example, no Peace Prize was given. It is the Nobel Foundation (基金会) that decides whether to give the prize or not. (1) A Nobel Prize is thought the highest honour because ________.
