泛读课文,勾选出本文的写作目的
I always think of my childhood experience in an African village. I would visit a
stream next to our home to get water for my mother. I would drink water straight
from the stream. I would play with the fallen flowers in the stream. And I would
try to touch all kinds of fish. But every time I put my little fingers under them,
they would go away. Later, I saw thousands of young fish swimming through
the clear water against the background of the brown earth. This is the world I
received from my parents.
Today, over 50 years later, the stream has dried up. Women walk long distances for water, which is not always clean, and children don’t even know what they have lost. It is not until now that I realize the importance of protecting the environment.
It’s time we took action for future generations! We should save water and make the best use of it. At the same time, trees should be planted as many as possible. What’s more, we can always go green by carrying our cloth bags while shopping and taking public transportation or shared bikes while moving around.
If everyone gets involved, we will be able to protect the home of the young fish and give back to our children a world of beauty and wonder.

Practice: Writing Task
环境是我们赖以生存的家园。请你以“Save the Environment”为题,写一篇倡议书,内容包括:

(2)我们应该怎样去保护它
(3)写作词数应为80 — 100个字左右。
Practice: Writing Task
Save the Environment
The environment is our home. We depend on clean air, fresh water and green lands to live. But now, pollution and deforestation are damaging it. So I’m writing this letter to call on people to protect the environment.
We can do small things to help. For example, we should save water by turning off taps after using them and reduce waste by recycling paper and bottles. We can also plant more trees and walk or ride bikes instead of driving cars.
Protecting the environment is everyone’s duty. Let’s start now to make our home cleaner and more beautiful.
