第二十三課: 

今天要學的一個片語是extra pounds。 Extra pounds說白了就是你身上多了幾磅肉，別以為是多買幾磅肉。最近的調查顯示，不用說肥胖，就是體重超重幾磅也會縮短一個人的壽命幾年- Just a few extra pounds could mean fewer years.

許多美國人都為自己體重超重而擔憂 - Americans are constantly worrying about extra pounds. 他們想盡辦法來減肥--They try all means to shed their extra pounds。很多人通過跑步，鍛鍊來減肥 - try to get rid of their extra pounds by running and exercising.可是飽餐一頓往往會全功盡棄，甚至再加上一，兩磅 - a big meal might add a couple of extra pounds! 今天學的一個片語是extra pounds...

今天要學的一個片語是risky business。 Risky business危險的生意，或冒險的事。好萊塢製片公司Viacom和美國電影巨星Tom Cruise分手。報紙的標題說：Cruise Is Risky Business，意思是和Tom Cruise繼續合作是危險的。Risky Business也是Tom Cruise 1983年拍的一部電影的名字。

Risky business在生活中到處都是。買股票是危險的投資 - Investing in stocks is a risky business. 借錢給你不信任的人是冒險的 - Loaning money to someone you don't trust is a risky business. 一個中學生說不得到他爸爸的同意就開他的車出去玩是危險的 - Driving my father's car without his consent is a risky business. 兩個人在吵架，你想調解？ Risky business!今天學的片語是risky business...
