A：Why are there still so many people overweight despite the current fitness craze?現(xiàn)在健身這么火,為什么還是有那么多人超重呢?

B：Well, there are certain factors that effect people's size and weight.嗯,還是有一些因素會影響人們的體型和體重的.

A：What are they?都有哪些因素呢?

B：One study said that low-income groups have a higher percentage of over-weight people than higher income families.有研究表明低收入人群超重的比例比高收入人群高.

A：Why?為什么呢?

B：The survey said that the low, income groups eat more junk food on a daily basis.說低收入人群每天吃太多的垃圾食品.

A：That makes sense. Probably less time to make dinner and the junk food is cheaper.可以理解,他們每天工作忙,沒時間做飯,垃圾食品又比較便宜.

B：And junk food contains lots of fat and oil. There is one final reason why so many people are fat.垃圾食品油脂含量又高.不過還有另外一個原因.

A：What's that?什么?

B：Nobody exercises any more-not even kids! The average American home has the TV on for 6 hours a day!現(xiàn)在很少有人鍛煉身體,甚至小孩都不鍛煉.家里電視一天至少開6個小時.

A：Wow! No wonder people are so fat. Say, Carl, looks like you could be doing a bit more exercising.天啊.怪不得人們變得這么胖.卡爾,你是不是也該鍛煉鍛煉身體了?

B：Yeah, I guess so.可能吧.

A：You should consider eating healthier food and getting some more exercise.你可要注意飲食了,多做鍛煉啊.

B：Hey, I started a diet and lost 10 pounds.我節(jié)食一段時間,瘦了10磅呢.

A：So what happened?后來呢?

B：Well, I quit and gained it back plus 5 pounds.我放棄了,結(jié)果體重反彈,又胖了5磅.

A：You should have kept trying.貴在堅持啊.
