The Average Family Expenses in X City
　　The two charts above tell us two facts. First, the annual income of average families in X city increased from $12,000 in 2008 to $16,000 in 2013, an increase of more than 33% in the five years. Second, with the rise in income the percentage of expenditure increased, too. Of the total expense, that spent on housing and food grew from 43% to 54%, which is an increase of 11% over the five years.
　　During the five years, the expenditure on housing grew by 7%, and on food, 4%. A possible explanation for the increase is that the greater earnings enabled families to eat better and live better, or simply because the prices on food and housing went up. If it is the former, we can assume that the people may look forward to a better life. But with the latter, they may expect a hard time ahead.             (153 words)

X城市的家庭平均开销
　　以上两个图表告诉我们两个事实。首先，X 市的平均家庭年收入从2008 年的12000 美元增加至2013 年的16000 美元，在五年内增加33％以上。第二，随着收入的增加，开销的比例也增加了。总开销中 ，用于住房和食品的花销从43％增加至54％，在5 年内增长了11％。
　　在这五年间，对房屋的开销增长了7％，食品的开销增长了4％。这一增长的一个可能解释就是，更多的收入使得家庭能够吃得更好，生活得更好，或者干脆说是因为食品和住房价格上涨。如果是前者，我们可以假设，人们可能期待一种更美好的生活。但相对于后者，他们可能会预知前面的生活很艰难。
