词：fathom
英英释义：to understand something complicated or mysterious
例句：Girls’ behaviors/intentions are often hard to fathom.
2. 体会这个词 （进阶篇）
“fathom“既是名词也是动词。作为名词，fathom 表示测量水深的单位“英寻”；作为动词，它表示“透彻理解”“深入了解”，今天我们要学习的是它的动词用法。和表示“理解”的常见词（比如 understand，comprehend，figure out）相比，fathom 有“深不可测”“绞尽脑汁也没有想透”的意味，在一些语境下使用 fathom 会更准确，在写作和口语中都可以使用。
比如，有首老歌叫《女孩的心思你别猜》，说的也就是有些女孩的行为叫人难以看透，我们可以用 fathom 造句：
Girls’ behaviors/intentions are often hard to fathom.
在口语表达中，难以看透某人或某事也可以直接说“I can’t fathom him/her/it”。再比如我们常说“问世间情为何物，直教人生死相许”，是不是也可以解读为：
It’s hard to fathom why people fall in love and how some of them would die for the one they love.
《经济学人》中也常出现 fathom，最后来看两个例子：
a) Higher barriers to trade will add to inflation and hurt GDP, but to an extent that is hard to fathom.
b) Of all the Trump administration’s many regulatory cuts, the unrolling of these modest improvements to school food is among the hardest to fathom.
3. 从认识到会用（作业）
1）翻译下面的句子：
我们难以理解“无条件的爱”意味着什么。
What's unconditional love truly means is hard to fathom.
It's hard to fathom what is means to love someone unconditionally.
（参考翻译：What 'sunconditional love' truly means is hard to fathom. 或者 It's hard to fathom what it means to love someone unconditionally.）
2）结合自己的生活、学习、工作、兴趣等，想象在什么语境下会用到这个表达。先简要描述这个场景，再造句。
场景：金融
造句：If investors are worried about the cloud of political uncertainty looming over Hong Kong, they have a curious way of showing it. Over the past five weeks, as a rancorous debate over the city’s democratic future spilled onto its streets, there has been a flood of demand for its currency. The territory’s de facto central bank,committed to a 31-year-old dollar peg, bought the $9 billion that streamed its way, to prevent the exchange rate from rising. It is hard to fathom the sudden influx. Hong Kong’s authorities pointed to technical factors as explanations, such as dividend payments and mergers that had forced companies to buy the currency in bulk.
