Baseball is America's national sport. So it is not unusual that many popular expressions come from baseball. But first, let me explain a little about the game. Each baseball team has nine players. The pitcher of one team throws the ball to a batter from the other team.棒球是美国最流行的运动项目.所以有很多源自棒球的常用语也不足为奇.但首先让我稍微解释一下这项运动.每个棒球队有9名球员,一队的投手将球投向另一队的击球手.
