【简答题】
Do you know 2022 World Cup will be held in Qatar( 卡塔尔 )? And FIFA( 国际足联 ) has made a big decision. The 2022 Qatar World Cup will be held in November and December. It is the first time FIFA has moved the event from its traditional summer to winter. According to the decision, the 2022 World Cup will start on November 21.The final will take place on December 18, one week ahead of Christmas. The tournament will last 28 days, half a week shorter than usual. FIFA said, “This is an important step for us. December 18, 2022 is a Sunday, and it's National Day in Qatar, so it fits perfectly.” Many people disagree that Qatar has the chance to hold the 2022 World Cup, since summer temperatures are very high—sometimes, the temperature may be about 50 °C . So the country has an idea to move it to winter. At last FIFA gave the chance to Qatar. Although the change is good for the players, there is still much opposition. The biggest opposition comes from the major European leagues( 欧洲联赛 ), because the new time will be just Europe's club season. FIFA said they would try their best to make things go well.
