【題目】根據(jù)短文內(nèi)容，從方框中選出五個句子填入文中空缺處，使短文內(nèi)容完整正確。

Soccer is the world’s favorite sport. In America people call it football. It has around 3 billion fans — nearly half the world’s population! 【1】 That’s 4 percent of the world’s population!

【2】 Many people in old days played early forms of this modern game. Cu ju (蹴踘), a ball-kicking game in China, was reported as early as 2,500 B.C. Around the same time in Greece, people were also playing a similar ball game without using their hands.

But modern soccer didn’t become official (官方的) until 1863. An Englishman called Cobb Morley introduced the idea of a football association (聯(lián)盟). 【3】 From then on, other associations in countries were set up. They came together to make up the FIFA, which organizes the World Cup. Thirty-two national teams play in the World Cup every four years.

It’s not easy to tell what makes soccer so popular. 【4】 Soccer needs only two feet and a ball. This makes it a sport that developing countries can easily play. Some of the sport’s best players come from these poor nations.

【5】 The sport’s no-hands rule makes beautiful dance-like movements on the field. What’s more, this sport excites the heart. Teams might score only a few times each match, so matches can turn around suddenly.

No one knows which country will win at the next World Cup. But one thing is certain: The world will be watching.
