二、实战练习
1. 图表作文
题目：以下是一张关于中国城市居民消费结构变化的图表，请根据图表内容写一篇短文。
解析：首先，观察图表，找出数据变化和趋势。然后，按照图表内容，分步骤描述数据变化，最后总结趋势。
范文：
As is shown in the chart above, the consumption structure of urban residents in China has undergone significant changes over the past few years. The percentage of food consumption has decreased from 57% in 2000 to 40% in 2010, while the percentage of housing consumption has increased from 15% to 25%. In addition, the percentage of education and medical care consumption has also increased, from 8% to 12%.
The main reasons for these changes are as follows. Firstly, with the continuous improvement of people’s living standards, they have more disposable income to spend on non-essential items. Secondly, the rapid development of the education and medical care industries has led to an increase in related consumption. Finally, the increasing awareness of health has prompted people to spend more on health care.
In conclusion, the consumption structure of urban residents in China is undergoing a significant transformation. This trend is likely to continue in the future, as people’s living standards continue to improve.
2. 议论文

范文：
With the rapid development of technology, online shopping has become increasingly popular among people of all ages. In my opinion, online shopping is a convenient lifestyle that offers numerous benefits.
Firstly, online shopping saves time and effort. People can purchase goods from the comfort of their homes without the need to visit physical stores.

Consumers can compare different products and choose the best one that suits their needs. Lastly, online shopping promotes the development of the e-commerce industry, creating more job opportunities.
