    There is not enough oil in the world now. As time goes by, it becomes less and less, so what are we going to do when it runs out? Perhaps we will go back to use horses, carriages and bicycles.
    In the Second World War, some people didn't use gas made from petroleum （石油）in their cars. They made gas from wood and plants instead. The cars didn't go fast, but they ran, so this was better than nothing. However, in the future, we can't cut down all our trees to make gas; we need our trees for other things, too.
    Besides different types of gas, we can also use electricity(电) to run our cars but first we must make the electricity! Some countries have coal and they make electricity with that, but we might not always have coal, either. Other countries have big, strong rivers and they can use the power of water to turn turbines(涡轮机) and make electricity more easily and cheaply.
    We are also able to get power from the ocean tides. We put turbines into the mouth of the river. Then the tide comes in, the water turns the turbines and then it goes out, it turns them again.
    Which of these ways will be used to run our cars in the future?

Zhalong is a nature reserve in Heilongjiang in north-east China. It is one of the world's most important wetlands. The reserve covers an area of 210,000 hectares. The area provides food and shelter for wildlife. It is an ideal home for different kinds of plants, fish and birds.
Many birds live comfortably in Zhalong Nature Reserve all year round, while some only stay there for a short time. There are many fish in the wetlands, and the birds can easily catch them for food. Zhalong has long been called “the home of the crane”. There are 15 crane species (物种) in the world. 8 of them are in China and there are 6 species in Zhalong area. It is an important living area for the rare red-crowned cranes. There are not many red-crowned cranes in the world. Every spring and summer, red-crowned cranes lay and hatch (孵化) their eggs in Zhalong.
Some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife. More and more birds are in danger because they do not have enough living space. Many of them died. The Chinese government wants to protect these endangered birds, and they can be safe in Zhalong.
Every year, a lot of tourists go to Zhalong to watch birds. This year, members of our Bird-watching Club are going to study the different kinds of birds in Zhalong and the changes in their numbers. The study begins next month.
We _______ once a year. We are now inviting secondary school students to help. We need more people to help us count and do something to help the birds.
Many people do not understand the importance of the wetlands. We hope this information will help them understand and make them actively take action to protect wildlife.

    People often say that the earth is like our mother. She gives life to all the living things on the earth and provides us with air, food, water and other essential things we need for living.
    Once she was beautiful and rich, but now she becomes dirtier and dirtier, poorer and poorer. It is due to what we have done to her. Please have a good look at her: polluted rivers and lakes, growing deserts, the destruction of the forests and wild life, and the depletion (消耗，用尽) of the ozone layer (臭氧层).
    Can she bear to see her children putting the waste here and there? Can she bear to see her children cutting down the trees and destroying the grassland, to see the acid rain destroying everything? Can we bear to see our mother suffering (受苦) so much? Isn't it time for us to ask ourselves whether this is the way to treat our mother?
    Floods, droughts, acid rain..., these are the punishments (惩罚) from nature. Everyone should know that there is only one earth. If we go on treating her like this, it won't be fit for us to live in any longer. It's time for us to love her, take good care of her and cure her. We should save the earth so as to save ourselves.

Can animals do work for us? Some scientists think that animals may do a lot of jobs. They say that we may see many elephants, monkeys, dogs, bears and other animals do a lot of things. Animals can get something to eat if(如果) they do some work for people.
Some scientists say that many different animals may do lots of jobs if they know they will get something to eat. Of course, dogs can guard a house, and elephants can do some heavy jobs. And we can also teach animals to work in factories. In America apes(猿) can help people make cars. Scientists believe that these big monkeys may drive cars.

On July 1, 2019, Shanghai began the waste sorting programme. There are four kinds of waste: wet waste, dry waste, dangerous waste and recyclable waste. Under the new rules, people must put their waste in the right place. Or they will be fined more than 50 yuan and less than 200 yuan.

Sorting waste is very important. By doing so, we can take out non-degradable(不可降解的)waste and save resources(资源)In return, we can get a better environment. ▲ Luckily. Internet companies like Wechat, Baidu and Alipay made apps to help.

How do we use the apps? Just open one waste-sorting app and write down the keyword. Then the app will tell us the answer and why, Alipay says its waste-sorting app got one million users in just three days and the number is still growing. They are working on the app and people may use it by taking photos in the future.

The waste-sorting programme is the talk of the whole country now. And another 21. 3 billion yuan will be used on the programme in 46 cities by the end of 2020.
