As is shown in the four pictures, there has been great change in Chinese diet since 1980s. Twenty years ago, people in the village always had corn, steam corn buns, sweet potatoes and vegetables as their main food. The urban people were comparatively rich, so they can afford the expensive dishes of rice, meat, eggs and fish daily. Nowadays it seems, to our surprise, the village people and city residents have exchanged their dinner tables.

The phenomenon reflects that people’s diet concept is changing while their living standard is progressing. On the one hand, with the improvement of the villagers’ living standard, the proportion of high-nutrition food, such as eggs and meat, has also increased in their diet. On the other hand, as many modern-day diseases, such as hypertension, high levels of blood lipids, and diabetes, are found to be diet-related disorders, the city dwellers have become more health-conscious, and they prefer the low-protein and high-fiber food to high-fat meals. 

Of course, we can’t judge hastily which eating habit is better, because only a balanced diet can benefit people’s body. However, it is a pleasure to see more and more Chinese people are pursuing a better life by choosing a varied and balanced diet.

This bar chart shows mobilephone subscriptions in developing countries and developed countries,measured in billions,for the years 2000 to 2008.The mobilephone subscriptions in both developing countries and developed countries enjoyed increase in different speed over time.In this chart,the mobilephone subscription in developed countries maintained a continual and steady increase from 2000 to 2007 and remained constant in 2008.Meanwhile,the mobilephone subscription in developing countries have undergone a slow increase from 2000 to 2004 and then saw a great surge from 2005 to 2007.This trend increased to a peak about 4 billion in 2008.Based on different national situations,the reasons leading to this trend can be summarized into two points.First,the developed countries have a limited number of population,which decides that the demand for mobilephone service is also limited and will soon be saturated.Second,as for the developing countries,it has a large population and also a large demand for mobilephone service.And as the mobilephone becomes more available and more affordable,there is an increasing number of people buying their mobilephones.In my view,this trend that the number of mobilephone subscription continues to grow in developing countries will be constant for a while in the future.And this trend would also benefit most of the mobile users both in the developing countries and developed countries.

The bar chart shows the general trend of university students whotake parttime jobs at different stages during their college life.Seeing from the chart,more than half of the college students,about 66.77%take a parttime job at their first year.And the proportion increases slightly year by year,til the last year,the proportion reaches the maximal number,surging to 88.24%.There are basically three reasons behind this trend.To begin with,most students are eager to take a parttime job in the purpose of earning some money,which can ease their parents'burden.Besides,they can acquire more experience before officially entering the society.And with more experience,they can easily get a job compared to those who do not have any experience.Finally,they can not only turn what they have learnt into the application,but also learn more which they cannot obtain from their books.In my view,getting a parttime job is a good practice.However,the major task of students is still the study.They should make a balance between their academic life and their working life.
