give the eye 拋媚眼，送秋波
無論是男生還是女生，只要他/她瞄準了看上了另外一個她/他，他就會give the eye，那就是說，他/她在暗送秋波，在眉目傳情，在表達他/她對另一位的興趣噢~!
如：
1. Willy, don't look now, but when you get a chance take a look at that girl sitting over there alone. I think she's in my biology class. And, you know something - I think she's trying to give me the eye. Maybe I ought to go over and say hello.
Willy, 你現在先別看。等一會有機會，你看一看那邊獨自坐著的那個女孩子。她好像是我們生物課裡的一個同學。你知道嗎，我覺得她在對我暗送秋波。也許我該走過去打個招呼。
2. Oh stupid guy, I have been trying my best to give him the eye. But there is no response at all!
天呢，他真是蠢死了，我已經盡力在向他拋媚眼了，他怎麼就不給個反應呢?!
give the once-over 非同一般地看某人
在這裡，once表示「一次」;over有許多解釋，如「越過」「上面」「完了」等。而這個短語的意思就是「非同一般地看某人」，實際上與give the eye的意思是一樣的。也就是說，在運用時，它倆完全可以換著用。再來看兩個例子：
1. When I give the once-over, she finally gave me a nice smile so I went over to tell her: "haven't we met someplace before?" She asked me to sit down and we got acquainted and look at this, Willy - she gave me her phone number!
當我盯著她看的時候，她終於對我笑了一笑。所以，我走過去對她說：「我們是不是以前在什麼地方見過面?」她讓我坐下，我們就這樣認識了。你看，Willy, 她把她的電話號碼都給我了。
【注】美國年輕人在想認識一個他喜歡的女孩子的時候往往會說，我們好象以前見過面吧- 也就是：haven't we met someplace before? 他們經常用這句話來問對方，實際上是借了這個話題來認識對方。
1. Hi, Toutou, look at the boy over there. He is looks awesome isn’t he? But obviously he is giving the once-over to another girl.
喂，偷偷，快看那邊的那個男生。他長得帥呆了!但是很顯然他卻在對另外一個女生暗送秋波。
size up 估量;符合要求
Size這個詞本身的意思是：尺寸。例如，一個人的腰圍有多大，胸圍有多大等。但是，size和up合在一起就成了習慣用語，意思是：當你剛見到一個男孩，或一個姑娘的時候，你對對方是否漂亮所形成的第一個印象。
如：
1. Oh, yeah, I'm settled down all right. I married Barbara about three years ago; as soon as I met her I right away sized her up as the girl I wanted to marry. It took her three more years to agree, but we've been very happy and already have a daughter with more on the way, I'm sure.
噢，對，我已經成家了。我大約三年前跟Barbara結了婚。我一見到她，我就覺得她是我理想的妻子。過了三年多，她才同意跟我結婚。我們現在很幸福，已經有了一個女兒，我肯定我們還會有更多的孩子。
2. Trust me, you will size her up when you two meet. She is quite your type.
相信我吧，你倆見面之後你肯定滿意，她太符合你這一類型了!
