Let us say I want to sell my car but I do not know exactly how much it is worth. If someone asks me the price, I might give a ballpark figure or a ballpark estimate. If someone offers me an amount that is close to my selling price, I might say the amount is in the ballpark. 假设我想卖车但不知道它的确切价值.如果有人问我这车的价格,我就会给出一个大概的数字(a ballpark figure or a ballpark estimate).如果某人的出价跟我的售价接近,我会说the amount is in the ballpark(差不多).
