我快没钱了。

　　dough本意为面包，没有钱当然就吃不起面包了。所以dough也有钱的意思。另外一个词breadwinner， 直译为赢得面包的人，可以理解为养家糊口的人。

　　2)He dropped 20 bucks on a shot of tequila, he is such a moneybag.

　　spend太被滥用了， 口语里面可以用drop，译为花钱。moneybag钱袋子，很有钱的人。(注解：shot 是一杯干的意思，tequila龙舌兰，一般tequila shot 不会太贵，大概$5 左右吧，当然能话20刀喝一个 tequila shot一定是个钱袋子吧)

　　3)She blew a grand on her trip to Beijing.

　　她去北京这一趟花了1000美金。

　　blow译为大手大脚花钱的意思，grand一千块。

　　3)gold digger拜金女，很好理解吧，挖金子的人。

　　举个栗子：

　　She is such a gold digger. She always goes for moneybags.

　　4)cheapskate 花钱很小心人，吝啬的人， 略有贬低的意思。

　　举个栗子：

　　I think I am going to break up with my boyfriend since he is such a cheapskate and not willing to take me out for a nice dinner.

　　5)被无良商家骗了怎么说呢?

　　I got ripped off by the car maintenance guy, and he took me for $200 for the repair work.

　　两个词组需要注意，第一个 sb got ripped off, rip有撕裂、剥的意思，被人剥了也就是被人骗了钱。第二个take someone for some amount 理解为被人骗了多少钱。

　　或者说： That guy really took me to the cleaners.

　　clean 干净，可以理解我被那个人掏空了。

　　被欺骗的人也可以做主语哦：I got taken by the car mechanic.
