【英语时差8,16】关于坚果的秘密

（单词翻译）

 Nuts, botanically speaking, are made up of both the seed itself and a hard outer layer that is the fruit, which does not split open when ripe. Some examples of true nuts are acorns¹, hazelnuts and chestnuts². Walnuts³, pecans and almonds, in contrast, are edible⁴ seeds from a bigger fruit. Most of the inedible⁵ fruit is removed at harvest so when you buy walnuts and almonds in the shell, you’re buying the seeds enclosed in woody endocarp, which is the remaining layer of the fruit wall. Brazil nuts are also seeds. They come from a capsule like fruit, in which several of the triangular⁶ seeds grow inside, arranged like the segments of an orange. Peanuts are the seeds of a legume, or member of the bean family. Pistachios, cashews, macadamias and pine nuts are all seeds rather than nuts.
