a needle in a haystack 这是要找针的节奏吗

haystack 是“干草垛”的意思，那么 a needle in a haystack 字面上就是干草垛中的一根针，可想而知那是什么概念了，相信每个人都知道这个习语的意思了，它可以意为“大海捞针”，寓意：

something very small amidst something very big

小东西在大东西中

an insignificant item to be searched in a huge pile

一大堆要搜索的无关紧要的东西

a difficult situation

困难的局面

something that is not likely to find since it is buried among lots of other things

一种不太可能找到的东西，因为它埋在许多其他东西中

例如：

Searching for one man in this big city is like looking for a needle in a haystack. 

在这座城市里寻找一个人犹如大海捞针。

You must be kidding when you say that you would like to find evidence in this case, it is like trying to find a needle in a haystack.

当你说你想在这件事上找到证据时，你一定是在开玩笑，这就像大海捞针一样。

I am not going to waste your time by asking you to find a needle in a haystack, instead I will give you the details myself in return for money.

我不会让你大海捞针来浪费你的时间，相反，我会自己给你细节来换取金钱。

She was trying to find her daughter like a needle in a haystack when she got separated in the mall. Instead she could have approached the authorities to help her find the girl.

当她的女儿在购物中心失散时，她正试图像大海捞针一样去找她。相反，她本可以向当局求助，帮助她找到那个女孩。

Knowing that being able to find the diamond in this mine is like finding a needle in a haystack, I’m not even going to try.

知道能在这个矿里找到钻石就像大海捞针，我甚至都不会去尝试。

其实不要说在大海里面找针了，就是在干草垛里面找都很有难度的。
