七、书面表达
参考范文:
Dear teachers and students,
As members of the "Green Future" environmental club, we are writing to call on everyone to protect wetlands. Wetlands are very important. They clean water like kidneys, prevent floods and provide homes for many birds and animals.
However, wetlands are in danger. Some are filled to build houses, tourists disturb the wildlife, and pollution makes the water dirty.
We can do our part to help. First, we shouldn’t throw rubbish near wetlands. Second, we can volunteer to clean up wetland areas on weekends. Third, we should tell our family and friends about the importance of wetlands.
Let’s work together to protect wetlands. They are our natural treasure, and we can’t live without them!
The "Green Future" Environmental Club
