Trees are an important part of the Earth. They provide
wood for buildings and things for making paper. They provide
homes for all kinds of insects， birds and other animals. For
example， many birds live in trees. Many kinds of fruits come
from trees， such as apples， oranges， pears and peaches.
Trees also help keep our air clean and our ecosystems healthy. We breathe in oxygen and breathe out harmful gases. However， trees breathe in harmful gases and breathe out oxygen. And trees can help other plants grow because they can hold the soil. Trees keep the soil from being blown away， so plants can fight against strong winds.
Trees do a lot for us， our environment and other plants

also be very beautiful and we can enjoy the beauty of them.

trees.

范文一(基础版)：
Good afternoon， everyone，
My name is Li Hua. I’m so glad to stand here and give my
speech. The topic of my speech is “Protecting trees”.

Trees
play a key role in our lives. 　









First of all， they can make our environment more beautiful. They also keep the air fresh， cool and clean， which is great for our health.What’s more， trees are like the “lungs of the Earth”. They take in harmful gases from the air and produce oxygen. They help us fight pollution. Besides， trees provide us with useful things—many furniture pieces are made of wood， and we can get delicious fruits from them.
To protect trees， we can plant more young trees in spring
and reuse paper to reduce waste. Let’s take action to save trees！
范文二(提升版)：
Good afternoon， everyone，
My name is Li Hua. I’m so glad to stand here and give my
speech. The topic of my speech is “Protecting trees”.


The
importance of trees can never be overlooked， as they are
important to both the natural world and human life.　






First， trees beautify our environment and keep the air cool and clean—breathing fresh air is good for our physical and
mental health. What’s more， trees take in carbon dioxide and produce oxygen. They also provide practical resources. We use wood to make furniture， and many fruits (such as apples and oranges) come from trees.





However， too many trees are being cut down now. To protect them， we can plant more trees in our community， reuse paper products， and stop cutting down so many trees. Trees are our silent friends. Let’s protect them to make the world a better
place.(共13张PPT)

三、阅读表达。(新题型：阅读短文，根据短文内容回答问题)
　　Trees are one of the most valuable resources on Earth. They
have been around for millions of years and have helped support
life on our planet.
Trees help clean the air. They take in harmful gases like
carbon dioxide and produce oxygen， which all living things
need to breathe. They also help reduce pollution by keeping dust
and other particles in their leaves.
Trees provide shelter and food for many animals. Birds
build nests in their branches， and squirrels store nuts in tree
holes. Many animals eat the fruit， leaves and seeds of trees.
Trees also help prevent soil erosion(土壤流失). Their roots
hold the soil together， especially on hillsides. Without trees，
rain would wash away the soil， making it hard for plants to
grow.
Unfortunately， humans are cutting down millions of trees
every year. This is called deforestation. Deforestation destroys
animal habitats and causes climate change. We must do our part
to protect trees. We can plant new trees， reuse paper and avoid
buying products made from illegal logging(非法采伐).
1. What do trees take in and produce？


2. Where do birds build nests？

trees.
【解析】根据第二段第二句可知答案。

知答案。
3. How do trees help prevent soil erosion？

4. What is deforestation？


【解析】根据第四段的“Their roots hold the soil together”可

【解析】根据第五段第一句可知答案。

Deforestation is when humans cut down millions of trees every
year.
5. How can we protect trees？


【解析】根据第五段最后一句可知答案。
We can plant new trees， reuse paper and avoid buying products
made from illegal logging.(共13张PPT)
