答案：
We often see people waste food because they order too much for their meals, or the food is not delicious enough or not properly kept.
A survey indicates each year China wastes 200 billion Yuan worth of food, which is enough to feed over 200 million people.
Food waste means wasting money as well as wasting precious resources. When food is thrown away, it becomes rubbish which can be harmful to the environment and people’s health.
It’s meaningful to join in the “Clean Your Plate”Campaign, which helps us realize how difficult it is for a grain of rice to come on our plate an how important it is to save food. It’s wise to order a proper amount of food for our meals. If there’re leftovers, it’s better to take them home. To save food, we should start with ourselves and start from now.
题目分析：考查开放式作文，考生在写作时要注意根据英文提示，切忌偏题，通过审题可知文章讲的是光盘行动的问题，要求紧扣材料，联系身边的实际，有自己明确的观点，开放式作文难就难在没有要点，给考生自由发挥的余地大，但也增加了难度，有的考生会觉得无话可说，这时可以充分利用所给的信息，展开陈述，但要符合英语习惯，句式选择要富有变化。在写作的过程中注意句型的多样化和连接词的使用。要求考生用地道的英语表达自己的观点，要求观点明确，驾驭语言的能力强，选择词汇的时候要选择相对高级的词汇，也要运用多种句型，让文章更有变化。难度在于选择合适的词汇和句型表达文章需要的意思，可以变换使用一些容易驾驭的句子或者词汇实现同样的目的。在写作的时候要运用合适的连接词把要点串联起来，使文章成为一个整体。
【亮点说明】A survey indicates each year China wastes 200 billion Yuan worth of food, which is enough to feed over 200 million people.这句话用的是非限制性定语从句， When food is thrown away, it becomes rubbish which can be harmful to the environment and people’s health.这句话也是定语从句， It’s meaningful to join in the “Clean Your Plate”Campaign, which helps us realize how difficult it is for a grain of rice to come on our plate an how important it is to save food.这句话有定语从句有宾语从句还有it形式主语， It’s wise to order a proper amount of food for our meals.这句话也是it做形式主语的用法。
