1 “承受力”/“意志力” 用哪个简单的词就可以表达？
比如：
我有时很有耐心，可有时我的承受力到了极限，我就撑不住了。
I can be very patient, and then I can burst if my nerves are worn out.
柯林斯词典对nerves的解释：if you refer to someone's nerves, you mean their ability to cope with problems such as stress, worry, and danger.
中文释义即为“承受力；意志力”--注意作这个意思的时候用复数：nerves
2 了如指掌 怎么说？
比如：
我对那个男人的生活了如指掌。
I know every inch of that man's life.
inch的地道用法~
Btw, 我可太喜欢这个电影了。↑
3 预付金：retainer
柯林斯词典的解释：a retainer is a fee that you pay to someone in order to make sure that they will be available to do work for you if you need them to. -- 定金；预付金
例子：
She was being paid a regular monthly retainer.
她每月得到一笔预付金。
4 deficiency用起来~
deficiency：缺乏，不足，缺点
例子：
你有在他的分析中发现什么不足吗？
Did you find any deficiency in his analysis?
5 legwork：体力活；跑腿的活
例子：
我不介意做点跑腿的活儿。（我不介意做些体力活，我不介意打下手）
I wouldn't mind doing the legwork.
有时也可以指需要去现场的活（跑腿嘛），在侦探、警匪片里经常可以看到听到这个词。
还是那句话：每天就5条，不贪多，相信积累的力量！
