作文
1. For this part, you are allowed 30 minutes to write a short essay based on the picture below. You should focus on the demoralization of society. You are required to write at least 150 words but no more than 200 words.
The Demoralization of the Society
The picture depicts a man who is eating breakfast says the porridge is not as delicious as last week, while the storekeeper answers that the porridge is just the one of last week. The nature of the picture reveals the demoralization of the society.
The phenomenon described by the picture continues to exist despite the exposure by the mass media. The reason is as well-known as that people want to pursuit more profits so they use materials in bad quality, poisonous elements or just like the storekeeper in the picture, ignore the expiration date of foods. In doing so, the cost will be reduced in great degree.
What people do reflects the demoralization of the society and people must think highly of it. On the one hand, the government should enforce market regulation, perfect relevant laws to protect the consumers’ rights. On the other hand, to improve the moral standard of whole society is the most essential and effective way. Virtues, such as honesty, integrity and consumer first, are necessary to develop and cultivate.
In a word, the phenomenon is a serious social problem which people must pay high attention to and solve as soon as possible.
解析： 1．这是一篇图画作文，且是根据图画来阐述自己对于相关问题的观点，故时态应为一般现在时；图画内容很关键，图画中出现了两行文字：“The porridge is not delicious as last week．”“It is impossible because it is the porridge of last week!”再加上题干中的提示“the demoralization of society”，可以看出这是一篇关于“社会道德问题”的作文。
2．综合图画和题干所提供的信息，可提炼出写作的主题——社会道德遭受挑战，不道德行为层出不穷。
3．确定写作思路：早餐店店主为谋取利益，不顾他人生命健康，用过期的食品赚钱，这一行为的普遍存在表明社会中的不道德行为应当引起政府和群众足够的重视。
