1. 认识这个词（基础篇）
词：hurdle
英英释义：a problem or difficulty that you must deal with before you can achieve something
例句：Life is all about jumping over one hurdle after another.
2. 体会这个词 （进阶篇）
“hurdle”是可数名词，本意是“栏架”，常被引申为“障碍”，常见、好用、形象。当我们想表达“克服XX障碍”“解决XX问题”时，除了使用 problem、difficulty、obstacle 外，还可以使用 hurdle。
我们经常会说，生活就是解决一个又一个问题，不断往前走的过程，就可以这么说：
Life is all about jumping over one hurdle after another and keeping moving on.（注意 and 连接的 jumping 和 keeping 的一致性。）
hurdle 前面经常搭配的动词除了上面的 jump over，还有 clear、overcome等。比如创业会面临一系列的挑战，例如融资、招人、持续增长等。我们就可以这么说：
To run a start-up, one needs to clear a series of hurdles, and securing enough funding is simply one of them.
通常还可以在 hurdle 前面加上一个形容词，来说明是哪方面的障碍。上面的句子也可以改写成：
Every entrepreneur has to clear the financial hurdle to get their project started.（hurdle 前面用 financial 修饰，说明是资金方面的障碍。）再比如，我们想说“滴滴在刚开始的时候需要搞定政府监管”，“政府监管”就可以说成是“regulatory hurdle”：
When Didi, a Chinese cab-hailing app, first started, it had to overcome the regulatory hurdle.
