To remember some words or phrase

Unemployed：if you are unemployed, you are avalible to work but don't have a job.

Example：

1、Thousands of workers became unemployed after the factory closed down.

2、Up to 60% of the unemployed have no collage degree.

讲解：“the”加形容词可以指代一类人；the unemployed指的就是失业者

To break down：when you break down, you lose control of your feelings and start to cry.

Example：

1、He broke down in tears when he deleted his ex of his phone.

讲解：可以用break down in tears或者break down to tears来表示某人泪流满面

2、Marsha broke down crying at the driver's kind, encouraging words.

讲解：除了break down in/to tears，还可以用break down crying。

个人理解：就语气来说，我感觉break down crying更加的能突出泪流满面的场面，不过我查了下字典，发现三者其实是一样的.....
