I think cigarette smoking is highly addictive and very expensive. Especially when you’re 14 and get a $9 weekly allowance. I’m in ninth grade and started smoking in sixth, the first cigarette I ever had was in fifth grade. My morn was walking our dogs and found an unopened pack that she brought home to use as an insecticide in the garden. A friend had told her that tobacco stops ants from attacking plants. Of course, when I found the pack, I took the cigarettes to my bedroom and, being the little rebel I was, lit one with matches I stole from Dad. The fact I was actually smoking made me think I was cool. But my friend Donna didn’t think so. She just looked at me like I was the stupidest thing on earth. Which I probably ,as, I still smoke to this day.

第三篇
"Clean your plate!"and"Be a member of the clean-plate club!"Just about every kid in the US has heard this from a parent or grandparent. Often,it's accompanied by an appeal:"Just think about those starving orphans in Africa!"Sure,we should be grateful for every bite of food. Unfortunately,many people in the US take too many bites.Instead of staying"clean the plate",perhaps we should save some food for tomorrow.
According to news reports,US restaurants are partly to blame for the growing bellies.A waiter puts a plate of food in front of each customer,with two to four times the amount recommended by the government,according to a USA Today story.Americans traditionally associate quantity with, value and most restaurants try to give them that.They prefer to have customers complain about too much food rather than too little.
Barbara Rolls,a nutrition professor at Pennsylvania State University,told USA Today that restaurant portion sizes began to grow in the 1970s,the same time that the American waistline began to expand.
Health experts have tried to get many restaurants to serve smaller portions.Now,apparently, some customers are calling for this too.The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believe restaurants serve portions that are too large;23 percent had no opinion;20 percent disagreed.But a closer look at the survey indicates that many Americans who can't afford fine dining still prefer large portions.Seventy percent of those earning at least ￥150,000 per year prefer smaller portions;but only 45 percent of those earning less than ￥25,000 want smaller.
It's not that working class Americans don't want to eat healthy.It's just that,after long hours at lowpaying jobs,getting less on their plate hardly seems like a good deal.They live from paycheck to paycheck,happy to save a little money for next year's Christmas presents.
Parents in the United States tend to ask their children_________.
A.to save food
B.to wash the dishes
C.not to waste food
D.not to eat too much
