Clear Your Plate Campaign
The Clear Your Plate campaign has recently been promoted around the world，urging people to save food by not wasting anything on the dining table.
You may not know over 30% of the world's food is wasted, while many people in poor areas do not have enough to eat. Therefore, it is of vital importance to save food. To begin with, do not order more than you need in the school canteen. In addition, it is suggested that take leftover food home when dining in restaurants. What’s more, we are supposed to call on family members and friends to take part in the campaign.
Reducing daily food waste by just 5% could save millions of people from starvation. Let's start doing what we can to make the world a greener, cleaner place!

范文 Our Oceans, Our Responsibility
June 8th was officially named by the UN in 2009 as World Oceans Day. It was set up to raise the awareness of protecting the oceans, which plays a crucial part in the global ecosystem.
Covering about 71% of the Earth’s surface, not only can the oceans regulate the climate, making the planet livable for humans, but also they produce over half of the world’s oxygen and are home to a large variety of sea life. Unfortunately, recent years have seen the oceans being polluted severely. Therefore, it is high time that we should take measures to restore them, such as collecting garbage on the seashore, avoiding pouring waste into the oceans as well as trying every means to fight against global warming, a great threat to sea creatures.
I am firmly convinced that only with joint efforts can we make a difference to our precious marine environment.
2009年，联合国将6月8日正式命名为世界海洋日。海洋在全球生态系统中扮演着至关重要的角色，它的设立是为了提高人们保护海洋的意识。
海洋覆盖地球表面的71%，不仅可以调节气候，使地球适合人类居住，而且还产生世界一半以上的氧气，是多种海洋生物的家园。不幸的是，近年来海洋被严重污染。海洋是如此重要，我们应该采取措施，通过多种方式来恢复它们，如在海岸收集垃圾，避免废水倒入海洋，以及尝试各种方法阻止气候变暖。
我坚信，只有共同努力，我们才能改变我们宝贵的海洋环境。
