Homework
Writing
Write an article for the school newspaper calling for everyone to protect animals.
You can follow the structure below:
◆ State the importance of protecting animals.
◆ Explain how human activities harm animals.
◆ Come up with ways to protect animals.
Writing sample
As we all know, animals are our friends. They make
our world beautiful and interesting. They are not only a
source of food, but also have their place in the balance
of nature.
However, human beings are making attempts to hunt
animals for food, fun or a big profit, which of course,
results in a sharp decrease in the number of animals. Some
rare species are threatened with extinction.
Writing sample
Therefore, it’s high time for us to take quick action to
protect them. First of all, it’s quite necessary to raise
citizens’ awareness of animal protection. Only by knowing
its significance can people develop a sense of responsibility.
In addition, the government should pass some laws to
forbid hunting for animals. In this way, we can build a
harmonious society and ensure a sustainable development.
