重点解释

Could it be done? Would it be worth the hunt?这个会实现吗，它值得我们去找吗

worth用法:

1.prep.(介词)

有些语法学家认为worth是形容词,但实际上worth更具有介词的语法特征,可支配名词短语,带逻辑主体的动名词和wh-从句,但不能跟主动不定式。

worth常用于sth is worth v -ing结构中,动名词短语在这里表示被动意义。本结构中的sth 有时可换用it,这时it是形式主语,动名词短语是真正主语。

2.n.(名词)

worth用作名词时意为“价值”,其前的名词主语如具有复数意义,则应采取复数形式并加上所有格形式'或 's 。

“...pounds worth+of+复数名词”在句中作主语时,在强调“价值”时谓语动词用单数形式,强调of的宾语名词时谓语动词用复数形式。

And this was the first discovery that we could actually find a way to slow down the ageing process with a single pill.而这是第一次让我们找到一种仅用一颗药就能减缓衰老的方法
