参考解析
解析：
根据Excerpt 4中的“The computer-penetration rate at the high—income level is an amazing 76.56 percent, compared with 8 percent at the bottom end of the scale.”可知，在高收入阶层中，拥有计算机比例是惊人的，达到76.56%，低收入阶层的计算机拥有率却只有8%。76.56%与8%相比，将近10倍，因此C项是正确答案。

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.What does the survey indicate?A:Many poor Americans want large portions.B:Twenty percent Americans want smaller portions.C:Fifty seven percent Americans earn ￥150,000 per year.D:Twenty three percent Americans earn less than ￥25,000 per year.
