Five easy ideas to help save the planet
The Earth needs your help. It’s warming up; the Arctic (北极) is melting (融化); the rainforests are getting smaller and smaller. But there are lots of simple, fun things you can do to save the environment.
Each year we throw away millions of mobile phones. But when the time comes to kiss your old phone goodbye, why not recycle it It takes 45 times less CO2 to recycle an old phone than to make a new one.
Planting new trees is as important as saving old ones. Choose a place where a tree can grow big and tall. Then sow (种) a tree seed and watch it grow. It’s the easiest thing, but possible the best thing you can ever do. Your grandchildren will thank you!
Help the planet to get fit. Cycling is a lot healthier, cheaper and more environmentally friendly than taking a bus. So ride your bike and reduce your carbon footprint.
You use a plastic bag for five minutes but it can take 500 years to decompose (分解). Producing plastic bags also contributes to global warming, and they often end up as litter or harm wildlife. So take your own bag to the shops or use biodegradable (可降解的) ones!
Human activity and pollution threaten (威胁) the environment. So, why not do a fun run to raise money for environmental groups It’s an interesting way to make others be aware of saving the planet from harm. Plus, you may also stay healthy while making efforts.

阅读下面材料，从题中所给的A、B、C、D四个选项中选出正确选项。
How green are you Do you know how to be green
We all need a healthy environment, but we produce waste every day and it is harmful to our environment. Though we are young, we can still do something to help. Here are some ideas for you.
Reduce
Reduce means “use less”. Don’t waste things. This saves money and reduces pollution. Before we buy something new, think whether it is really necessary or maybe the old one is still useful.
Reuse
Reuse means “use again”. When we buy things, make sure that they can last a long time. When something is broken, we should repair it instead of throwing it away and buying a new one. Don’t use a paper cup or a paper bag. It’s better to use a china (瓷) cup and a lunch box because you can use them again.
Recycle
Recycle means “change things into something else”. Though it takes energy to change something into something else, it’s better than throwing things away or burning them.
So please remember these words: reduce, reuse and recycle.
7．What is the passage about
A．How to produce things. B．How to burn things.
C．How to be green. D．How to help others.

10．It is better to use a china cup and a lunch box because we can ________ them.
A．reuse B．reduce C．repair D．recycle
Every year on October 4 the world comes together for animals everywhere. This is World Animal Day:
It started in 1931 in Florence, Italy when ecologists banded together to raise awareness of endangered species, Since then, the yearly event has been used as a means of connecting “animal welfare (福利) organizations, youth clubs, business, community groups, and individuals...” to raise awareness for their work and fund raise in support of causes ranging from care of working animals to protection of endangered tigers and habitat loss.
Over the years, China has done much for domestic and wild animals. The protection of Asian elephants is a good example.
Asian elephants have become endangered because of hunting for their ivory tusks (象牙). Asian elephants in China are mostly found in Yuwan province. These wild animals sometimes eat local farmers’ crops. The government has been trying to create a more friendly relationship between local people and wildlife. For example, they ban (禁止) ivory and make rules for building separation facilities (隔离设施) to keep away wandering (游荡的) wild animals.
In the spirit of World Animal Day, we all can think more of ways we can better protect both the animals around us and those in the wild.
11．According to the passage, what can we learn about World Animal Day
A．It falls on December 4 every year. B．It works to protect animals.
C．It started over 100 years ago. D．It is only celebrated in Italy.
12．Why are Asian elephants in danger

① Man has known more and more about space today. Space is not only wonderful but also dangerous. While working in space, astronauts are facing danger.
② Scientists have found out that radiation (辐射) is the greatest danger to astronauts in space. When astronauts are working in space, they are in danger of radiation from the sun and other stars, which is bad for their health. The damage of radiation is difficult to discover until their children or even grandchildren are born. Some special medicine may work a little, but there isn’t really helpful medicine.
③ Space rubbish is also a great danger to astronauts. There are 9000 man-made (人造) things flying in space. About 30% of these are man-made satellites (卫星), 10% are spaceships, and others are space rubbish. Even a small piece of these knocked against a spaceship window and did some damage. Scientists are watching and telling any possible danger all the time. They are working on helpful ways to do with space rubbish.
④ Although space is really dangerous, everyone on the earth is interested in it. In the near future, it may become usual for people to spend a few days in a space hotel. We may even choose to leave the earth and live in space for a few years. So we should care for space and do something to help improve the space environment.
17．Who is in danger of radiation in space
A．Scientists’ children.
B．People on the earth.

In the past nine years, Li Jin, who was born in Guangxi but raised in Sanya, has made great efforts to protect the waters of Sanya city in Hainan. He is now spreading the knowledge of environmental protection through new media platforms (媒体平台).
Around 2014, he began doing volunteer work to clear rubbish from the beaches and officially registered (注册) as a volunteer in May, 2017. Li Jin immediately took the lead in a cleanup activity on the Sanya River.
In April, 2021, he used his own money to set up a volunteer service center which has 1,170 registered members who take part in activities without asking for payment. So far, he has spent about 3,800 hours on volunteer activities in over 550 events. More than 2,300 people have joined in with his encouragement. They’ve drawn the attention of both the adults (成年人) and the children to the importance of protecting the oceans and beaches. Since it was set up, his center has organized 51 beach-cleaning activities that have seen about 1,800 people join in. In 2021, because of Li’s growing influence in environmental protection circles, the city government invited him to make a number of short videos, in which he uses simple words to explain how to protect the environment. Several of the videos have been watched millions of times.
“My volunteer work would be meaningless if I got paid. But the work itself is of great value. So I will continue doing the environmental protection work.” he said.

Space junk is a danger to the satellites and may hurt astronauts. There are tens of millions of pieces of rubbish in space. Some of the pieces are from passing comets, but most of them are from large broken satellites and rockets after they stopped working.
Though satellite technology offers some advantages to people, the increasing use of it could make large areas of Earth’s orbit into bad condition. The space closely around our planet is becoming increasingly crowded with over 9,000 satellites in orbit today, and the Eastern Southern Observatory (ESO) shows that this number may grow to 75,000 by 2030.
As reported in October 2022, the International Space Station (ISS) had to think about how to keep clear of a piece of space junk from a broken Russian satellite in 2021. In November 2021, astronauts in the ISS had to stay inside their spaceship when the space station passed close to space junk.
NASA scientists have called for an agreement to make sure “space junk” doesn’t make the activities in Earth’s orbit into trouble and they are working on it. “Satellites are important to the people and Earth itself. However, using too much space will put our planet into a dangerous situation,” said Melissa Quinn, Head of Space port Cornwall. “I hope all countries need to pay attention, to understand the importance of the next step, and to work together, to keep the problem under control.”
25．The underlined word “it” in Paragraph 2 refers to ________.
A．space B．Earth C．rubbish D．satellite technology
26．The report in Paragraph 3 mainly shows that ________.
A．the Russian satellite has just badly broken
B．a piece of space rubbish can be very dangerous
C．the main job of the ISS is to collect the space junk
D．space rubbish is everywhere around the space station
27．Which of the following is True according to the passage
A．Most of space junk are pieces from passing comets.
B．There may be 75, 000 satellites in the earth orbit by 2030.
C．NASA has already kept the “space junk” problem in control.
D．Scientists think the space junk won’t hurt astronauts any more.
28．The writer wrote the passage to tell us ________.
A．it’s time to do with space junk problem B．it is dangerous to work in space
C．broken satellites may become space junk D．there is much space rubbish in space
How do you go to school every day By bike or on foot Maybe you can try a new way—taking an S’Cool Bus. The S’Cool Bus is also called the bike herlands is a bike kingdom. Someone invented this kind of bicycle in Netherlands.
It’s interesting for kids to ride the bike bus together to go to school. Also, it is very safe. The bike bus has a driver and eleven seats for kids. Each one has a helmet and safety belt (安全带). There is a roof (顶) on the bus. It can be used on hot days or rainy days.
Peter is a 10-year-old boy. He becomes a big fan of the bike bus. “Now the S’Cool Bus is my favorite way of vehicle (交通). I can ride it together with other kids to keep healthy. It’s full of fun.” For most parents, it can help them save a lot of time because they don’t have to pick up their children after school.
The S’Cool Bus is becoming more and more popular in some countries like Germany and France. Its inventor (发明者) Thomas Tolkamp says, “I hope I can sell the bike bus to more countries in the future. As the green lifestyle (生活方式) becomes popular, ideas like this get popular, too. I think it will work well in other countries.” The use of S’Cool Bus shows us that we can save the Earth in many ways as long as we want to have a try.

The world is changing all the time. Life today is getting easier than it was hundreds of years ago, but the changes have brought some new problems. One of the biggest problems is pollution. We can see it, smell it, drink it, and even hear it.
People are building the Earth but they are also polluting it at the same time. The more people there are, the more pollution we have. People always take away farmlands to build houses or factories. They kill animals to eat them or make money with their fur. They throw waste things here and there and dump waste water into rivers directly.
Now air pollution is still the biggest one in all kinds of pollution. It is bad for all living things. That’s mainly because of the heavy traffic. Some scientists say it will be much better if people ride bikes instead of driving cars. When you are riding, there is no pollution. But in many countries, people don’t want to go to work by bike. It is not because bikes are expensive or people are tired if they ride to work, but because the roads for cars become better than before. More people put away their bikes and go to work by car or by bus. Then things are getting worse and worse.

Scientists are trying to make the deserts into good land again. They want to bring water to the deserts, so people can live and grow food. They are learning a lot about the deserts. But more and more of the earth is becoming deserts all the time. Scientists may not be able to change the deserts. Scientists think that people make deserts. People are doing bad things to the earth.
Some places on the earth don’t get very much rain. But they still don’t become deserts. This is because some green plants are growing there. Small green plants and grass are very important to dry places. Plants don’t let the hot sun make the earth even drier. Plants don’t let the wind blow the dirt away.
