时差N小时 黄金是黄色的吗?(上)

（单词翻译）

Many people associate the metal gold with the color gold.

很多人认为金子应该是金色。

But, some gold jewelry¹ is not golden at all: it’s white.

但一些黄金首饰的颜色并不是金色，而是白色。

Gold is one of the heaviest and softest metals. Pure gold, called 24-carat gold, is so soft that it can be easily dented².

黄金是最重也是最软的金属之一。纯金，即24k金的质地非常软，很容易产生凹陷。

In the movies, old-time prospectors³ bite on yellow nuggets to see if they’re real gold because 24-carat gold will show a bite mark.

在电影中，以前的勘探者通常会咬一下黄金来试验是否为真金，因为24k黄金会出现咬痕。

In the real world, jewelers don’t want to use metal that can be dented so easily. So, most jewelry is actually an alloy⁴ of gold with harder metals.

然而现实世界中，珠宝商不希望使用那种易产生凹陷的金属。因此，大多数珠宝其实是黄金与其他硬金属铸成的合金。

Since pure gold is called 24-carat gold, an alloy of half gold and half other metals is called 12 carat gold, because, well, 12 is half of 24.

由于纯金被称为24k金，那么由黄金和其他金属各半铸成的合金被称作12k金，因为12是24的一半。
