原著这一句
“Well, I’ll eat it,” said Alice, “and if it makes me grow larger, I can reach the key; and if it makes me grow smaller, I can creep under the door; so either way I’ll get into the garden, and I don’t care which happens!”
“好吧，我吃了它，”爱丽丝说，“如果它能让我变大，我就能够到钥匙；如果它让我变小，我就可以从门下钻过去；所以不管怎样我都能进到花园里，不论发生哪种情况我都无所谓！”
