The three superstars were arriving at the airport and a large crowd of young people had already gathered there to welcome them．The police found it dificult to keep order after the plane landed and the performers appeared ．They smiled and waved cheerfully at everybody．Dressed in the same pink shirts and light blue trousers,with long hair and musical instruments over their shoulders,they all looked alike ．
Although there were many policemen present ,the Blare were not able to get to their waiting car _easily_ at all.Word spread that they had composed a new song which would be _heard when they performed at the concert that evening．They were now greeted _ with loud cries of " Play your new song!Play your new song!"
When the stars prepared to sing as the price for getting away,even the policemen looked surprised ,too.The tans settled down and listened to the first performance _ of the new song．Once it was over,everyone started jumping,clapping and shouting _madly .Several young women even fainted（昏倒） with excitement and were carried away immediately by the policemen standing by.The fans were greedy for more,remanding a repeat performance．Once again,the performers had no choice but to give in ,but when they were asked for still another song,they cheerfully but firmly refused．Closely surrounded by the policemen,they walked towards their car some distance away .The fans pushed forward,but the policemen,_ locked arm,prevented anyone getting trough.It took the stars quite a long time to reach their car

告诉我到底是哪个吧Orz……虽然有答案,但是我怎么就觉得其实这四个选项都可以啊……
第一个和第二个为什么不能选啊？这两个单词在前文中都有出现过，也都是 喊叫，尖叫 的意思，为什么不选这两个而选第三个呢？第四的选项看起来也没错啊……
