·1. bite the hand that feeds you·
bite /baɪt/ 动词，“咬”，注意时态变化是bite-bit/bɪt/-bitten/'bɪtn/；feed /fiːd/ 动词，“喂食”，feed-fed-fed /fed/。
bite the hand that feeds you是个习语，表示to harm someone who has helped or supported you，伤害那些帮你的人，白眼狼一样。
例：Your friends have had your back through everything, and now you want to turn on them? That's biting the hand that feeds you, isn't it?
你朋友一直支持你，现在你却想背叛他们？这不是恩将仇报吗？have sb's back表示to support and protect sb，支持帮助保护某人，口语里用。turn on sb表示to attack somebody suddenly and unexpectedly，突然攻击伤害某人，背叛某人。
A: I'll tell the boss you helped me with the office party. It was so much fun.
我会和老板说是你帮我组织办公室的派对。真的办得太好了。
B: Don't bite the hand that feeds you. If you tell him, he'll expect me to help every time.
你别恩将仇报哦，你要是和他说，以后每次他都会让我帮忙。
·2. This is how you repay me?·
repay /rɪˈpeɪ/ 及物动词，最基本的含义是to pay back money that you have borrowed，借钱之后还钱给别人，常用结构4个：repay sb, repay sth, repay sb sth, repay sth to sth。
例：我会还你钱的。
I'll repay you. I'll repay the money.
I'll repay you the money.
I'll repay the money to you.
不过日常口语表示“还钱”时pay back更常用：
I'll pay you back.
I'll pay you back the money.
repay还可以表示to do something for someone, or give them something, in return for helping you，别人帮你了之后回报、报答他们，常用结构是repay sb (for sth), repay sth with sth。
例：How can I ever repay you for your support?
我该怎么报答你给我的支持呢？
例：She repaid our trust with betrayal.
我们对她的信任换回的是背叛。
之前看过反问句“就这?”的句型，This is how you repay me?也是个反问句，“(我为你做了那么多)你就是这样回报我的？”在别人没有回报你或者恩将仇报的时候说的，欧美影视剧里经常看到。
类似的说法还有This is what I get (for helping you)? 我帮了你，我得到的就是这个吗？
例：I lent you money when you couldn't pay your rent, and now you're avoiding me when it's time to pay me back? This is how you repay me?
你没钱交房租时我借给你，现在到了还钱的时候你却躲着我？你就是这样回报我的？
·3. ungrateful·
/ʌnˈɡreɪtfl/ 形容词，表示not showing or expressing thanks for something that somebody has done for you or given to you，对别人的帮助不知感恩，经常用来形容人的某个行为或举动。
ungrateful的含义比恩将仇报广，恩将仇报只是ungrateful的表现之一，收到帮助不说谢谢、不懂回报、不领情等行为都是ungrateful。
常用结构是be ungrateful to sb, be ungrateful for sth, be ungrateful to sb for sth，不感激别人为你做的事。
例：I helped him move and he was so ungrateful. Didn't even say thank you.
我帮他搬家，他一点都不感激，连句谢谢都没说。
例：I made you dinner, and now you're telling everyone I'm a terrible cook. That's just ungrateful!
我煮晚饭给你吃，你还到处跟人说我厨艺很烂，太不厚道了！cook在这里是名词，“厨师、做饭的人”。
例：He was ungrateful to his friends for all the advice and support they gave him.
朋友给了他那么多建议和支持，他一点都不感激。
