高频英语口语：a needle in haystack(大海里捞针)
我们今天学习一句英语口语： It's a needle in a haystack
它的中文意思是：草垛里找针，大海捞针。
现在的问题是，你以为你用中文“学会”了一句英语： It's a needle in a haystack是中文“大海捞针”的意思，你下次再见到英语 It's a needle in a haystack时，还是只会“说”中文“大海捞针”吗？
下次我们再见到或者想表达 It's a needle in a haystack时，我们必须具备不说它的中文，而说它的英语意思的能力：这也正是我们的英语口语。
下面的英语你学过，会说吗？
1. When we say：It's like a needle in a haystack,we mean：We are having great difficulty finding something.
Have difficulty in finding学过吗？会用吗？
2. Well, it's a needle in a haystack means ：Something is very difficult to locate,or to find.
现在来练习练习：
1. Well,I lost my key somewhere in my living room and I searched for it/looked for it everywhere,but could not find. It’s like looking for _________!
2. Trying to find my contact lens on the floor was like looking for a needle in a haystack.
