Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and men can't make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore, animals and men need plants in order to live. This is the reason why we find so many plants around us.

    If you look carefully at the plants around you, you will find that there are many kinds of plants. Some plants are large while others are small. Most plants are green.

    Some plants have many small leaves. Others have only a few. There are many kinds of leaves. Leaves are of different shapes and colors.

    Leaves are also different in other ways. Some leaves have long thin parts at the end, we call them leaf stalks, some have short leaf stalks, others even have no leaf stalks. The leaf edges are also different. Some leaves have smooth(平滑) edges. Some have a wave-shaped edges. Others have edges like the teeth of a saw(锯子).

    Over 80G of the ancient forests have already been destroyed. Thousand-year-old trees are cut down just to make everyday goods. More and more wild animals are in danger now. Wild animals are our friends, and we cannot live without them. If we take no action, more and more wild animals will disappear in the future. It is time for us to save and protect endangered animals. Then what can we do? Here are some steps.

    Step one: Find out what animals are living near your place. Spend some time learning about the animals.

    Step two: Help to build more nature reserves and other wilderness areas. Protecting the living areas of wild animals is one of the best ways to help protect endangered animals. You can raise money for them or spend some time helping build nature reserves.

    Step three: Buy foods and goods that are made from materials which do not harm endangered animals or their living areas.

    Step tour: Join a local Wild Animals Club. You can take action to protect wild animals. There are many global groups that try to call on people to protect the environment by changing people's ideas and behaviours. Children, teenagers, teachers and schools from all over the world can help to save the animals. Everyone can do a little to help them, and every little bit of help is important!

My advice

Dear 8th-graders,

Wish you all the best!

The 9th day of the 9th lunar month is the traditional Chongyang Festival, which falls on Oct. 4th this year. "Chong" means "double" in Chinese. 1 , as double ninth was pronounced the same as the word to express "forever", Chinese ancestors considered it a good day worth celebration. That's 2 ancient Chinese began to celebrate this festival long ago. 

People follow several customs on Double Ninth Festival. For example, people often 3 the cornel (山茱萸) on their arms or heads because they believe this plant can prevent diseases and avoid disasters. Besides, people like to climb 4 on this day, so Double Ninth Festival is 5 Mountain Climbing Festival. The 9th lunar month often has autumn skies and fresh air. It is a good time 6 sightseeing. When people stand on a high mountain, they will have a good view of a blue sky and dark green mountains, which makes 7 carefree and joyful. Chongyang Cake is also known as "flower cake". It is said that the 8 was originally (最初) prepared after autumn harvest, because farmers wanted to have a 9 of what was just in season. Then gradually it became the cake for people to eat on Double Ninth Festival. Double Ninth Festival is a festival for the 10 . People get together to show their love and concern for their parents and their grandparents. 

Do you know how to start a club at school? Here are some helpful ideas for you:

The Earth is the energetic planet that we call home. It was formed over 4.5 billion years ago. The Earth might seem like a rock ball, but it's actually made up of four different parts.

The inner core (核心) is at the centre of the Earth. It's a hard ball of hot metal, about 70 per cent the size of the Moon. The temperature of the inner core can be as high as 5,400℃ and it's the hottest part of the Earth. The outer core circles (环绕) the inner core. Unlike the inner core, it is a liquid (液体的) layer, made mostly of iron. It's almost as hot as the inner core.

The mantle (地幔) is a thick layer. It circles the outer core and is about 2,900 kilometres thick, making it the Earth's deepest part. The mantle is mostly made of rock, but it also includes some magma (岩浆). The magma melted (融化) under high heat and pressure. It finally comes out from volcanoes.

We live on Earth's crust (地壳), a layer of rock about 30 kilometres thick. That might seem thick, but it's actually very thin, considering the size of Earth. There are two types of crusts: the mainland crust, which carries land, and the oceanic crust, which carries water. The thinnest parts of the crust are under the oceans, and the thickest parts are under the land. The Earth's crust is divided into large plates. Scientists believe that these plates are moving all the time, which explains how the world looks.
