Here is a picture about the inpediture on fast foods by income groups.
From the picture,we can get as much as information we want.Three parts consists of the whole form,namely high income,average income and low income.Also,in each income,there are still three kinds of fast food,hamburgers,fish and chips and pizza.In the highest income,hamburgers are in the majority which at the percentage of 42 a week.Pizza is in the second place,better than that of fish and chips.In the next two parts,pizza income is far away from the others.So we can draw the conclusion that people now are really having a busy life that they don't have enough time to eat home.They are paying too much attention to their work,which is the cause of the rapid development of fast food.
From what has been said above,it showed our favor for fast food.But I still suggest us a balanced life.To eat healthy,to eat happily.

追答嗯,可能是我看错了。语法应该是没有问题的!我看过了。
