143. Where’s My Flu Shot

Flu shots cost $20 at the drugstore. Only a few people are buying the flu shots. There are no long lines. No one is waiting in line. If you want the flu shot, pay $20. You don't have to wait in line. You can get the flu shot immediately. The mayor announced free flu shots. He said, "We will give free flu shots to everyone. Come to the library on Saturday." On Saturday 2,000 people went to the library. They stood in line for four hours. After four hours, there were no more free flu shots. They ran out of free flu shots. The drugstore still has many flu shots. But the flu shots at the drugstore aren't free. They cost $20.
流感疫苗在药店需要20美元。只有少数人在购买流感疫苗。没有长长的队伍。没有人在排队等候。如果你想注射流感疫苗，请支付20美元。你不需要排队等候。你可以立即得到流感疫苗。市长宣布了免费的流感疫苗。他说："我们将给每个人免费注射流感疫苗。周六到图书馆来吧。" 星期六，有2000人去了图书馆。他们排了四个小时的队。四个小时后，不再有免费的流感疫苗。他们的免费流感疫苗用完了。药店仍然有很多流感疫苗。但是药店里的流感疫苗不是免费的。它们需要20美元。
