Three kinds of fruit the graders had to watch out for: decayed oranges, split oranges, and "culls."
学生们必须注意这三种橘子：腐烂、劈开和“次等品”的橘子。
A cull is an orange that is too large or too small, or badly shaped or sunburned.
“次等品”是指过大或过小、畸形或有晒斑的橘子。
Quickly the graders rolled the fruit over with gloved hands.
工人们戴着手套很快把橘子分门别类。
The decayed or split fruit was thrown aside. The culls were tossed upon a separate belt
腐烂或裂开的橘子被扔到一条单独的皮带上。
which carried them away to be sold at a low price.
水果通过皮带被运走，以低价出售。
Jane felt her head whirl as she watched the wide, moving belts with their loads of jostling oranges.
简看着移动的宽带搭载着成堆的橘子，顿时觉得头晕目眩。
Suddenly she gave a little gasp of surprise.
突然，她惊讶地倒吸了一口气。
"Why, the oranges are disappearing!" she cried.
“哎呀，橘子不见了!”，简叫道。
And so they were. "Each orange," said the guide, "as it travels along, finds an opening exactly its size.
是的。“每一个橘子都不见了，”向导说，“橘子在前进的过程中会遇上和它一样大的开口，
Through this opening it rolls down into a bin where a packer can easily reach it."
橘子通过这个开口滚到一个箱子里，包装工人能轻易地够到。”
"Why, Mother," Jane exclaimed, "it's almost like the game I used to play!
“哎呀，妈妈，”简叫道，“这跟我以前玩的游戏差不多!
Don't you remember the little box I have at home, with tiny balls in it, that have to be shaken until they find the little nests that fit them?"
你还记得家里有个小盒子，里面装着小球，摇一摇，直到它们找到适合的小巢吗?”
