1 . Many people know that rubbish is a big problem on the Earth. What many people don’t know is that rubbish is becoming a problem in outer space too. Years of space exploration (探索) have left tons of “space junk” (太空垃圾) around the planet.
According to the reports of BBC, there are more than 22,000 pieces of rubbish in space around the Earth. And these are just the objects that are easy to see. There may be millions of smaller pieces of rubbish that we can’t see.
The pieces of space junk move around the planet at very high speeds. They move so fast that even a very small piece can become dangerous. If they crashed (碰撞) into each other, it could cause explosions that might even hurt people on the Earth. If the tiniest piece of rubbish crashed into a space shuttle (航天飞机), it could blow open a hole as big as an elephant.
To help solve this problem, countries around the world have agreed to limit the time their space tools stay in space to 25 years. Each tool must fall safely into the Earth’s atmosphere, or upper parts of the sky. There, it will burn up, and it won’t crash near the Earth.

2 . Threequarters of a million tourists flock to the white beaches every year, but this booming industry has come at a price. Poisonous smoke rising from open fires, rubbish made up of plastic bottles, packets..., it’s a far cry from the white sands, clear waters and palm trees that we associate with the Maldives (马尔代夫), the paradise island holiday destination set in the Indian Ocean.
Of its 200 inhabited islands, which are spread across an area of 35, 000 square miles, 99 are good resorts (旅游胜地)．So many tourists come every year, more than double the local population. Of these, over 100, 000 travel from the UK. The capital, Male, is four times more densely populated than London. Given these facts, it’s hardly surprising that the Maldives has a waste disposal problem.
Years ago, when the tourists left, the government had to deal with a stream of rubbish. Their solution was to turn one of the islands into a dumping ground. Four miles west of Male is the country’s dumping ground, Thilafushi.What you are seeing here is a view of the Maldives on which no honeymooners would like to clap eyes.Each visitor produces 3.5 kg of waste per day.The country dumps more than 330 tons of rubbish on the island every day.
Now, since many waste boats, tired of waiting seven hours or more, directly offload their goods into the sea, the government of the Maldives has banned the dumping of waste on the island. So, the waste boats ship the rubbish to India instead.

3 . JP Morgan Chase, the world’s biggest fossil fuel funder, has noted in an internal report leaked to Extinction Rebellion that the company “cannot rule out catastrophic outcomes where human life as we know it is threatened.”
Most of the science inside the report is not shocking to the casual reader, but the analysis is most concerned about climate change caused by fossil fuel. These include possibilities like the sudden collapse of the West Antarctic ice sheet, which would send sea levels more than 10 feet higher than current levels and displace millions of humans. Another terrible case is that the melting permafrost sends more carbon dioxide into the atmosphere, causing more warming, and in turn more the melting of ice sheets, and carbon emissions. Of course, these are already happening. The real danger behind the motivation for this internal report lies in the possibility that the Earth’s climate could reach a tipping point.
Many believe the emergence of the internal report should serve as proof convincing enough for world leaders to take collective and decisive action. However, the attitude of many world governments towards the development of fossil fuel can surely make the global situation even worse for future generations now.
However, the report doesn’t mention other banks, or even JP Morgan itself, even though these institutions are often the ones blamed in enabling this crisis, according to a Gizmodo report. “Changes are occurring at the micro level, involving shifts in behavior by individuals, companies and investors,” says the Extinction Rebellion report. It goes on to suggest that these micro-level changes “will push emissions in the right direction,” but says nothing about government oversight, or actions that many believe is necessary to reverse the current course of the climate crisis.
It’s still half way even though one has made 90 miles out of a 100-mile journey. Humans may still fail the journey if they doesn’t persist to the last. Therefore, something will have to change at some point if the human race is going to survive.

4 . The world itself is becoming much smaller by using modern traffic and modern communication means. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution. To pollute means to make things dirty. Pollution comes in many ways. We see it, smell it, drink it and even hear it.
Man has been polluting the earth. The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. When the land was used up or the river was dirty in one place, man moved to another place. But this is no longer true. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad for all living things in the world, but it is not the only one kind of pollution. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal in houses and factories in the city, and from putting dirty smoke into the air.
Pollution by SO2 is now the most dangerous kind of air pollution. It is caused by heavy traffic. We are sure that if there are fewer people driving, there will be less air pollution.
The earth is our home. We must take care of it. That means keeping the land, water and air clean. And we must take care of the rise in pollution at the same time.
1. Hundreds of years ago, life was ________ it is today.| A．much easier than | B．as easy as |
| C．much harder than | D．as hard as |
| A．rubbish | B．noise pollution |
| C．air pollution | D．water pollution |
| A．it makes much noise | B．it makes us angry more easily |

| B．The pollution of the earth grows as fast as the world population does. |
| C．The problem of pollution is not so serious because there are not so many people living on the earth. |
| D．If people could go to work by bus or bike instead of car or motorbike, it would be helpful in fighting against the problem of SO2. |
5 . According to the WHO, 90 percent of the world’s population lives in a place where they are exposed to unsafe levels of airborne pollutants, contributing to up to seven million deaths each year. If you live in a city, chances are that you’re part of that 90 percent, even if your city is relatively clean. That’s why cities worldwide have started embracing Internet of Things (IoT) solutions.
One of the best ways to fight pollution is to figure out where it’s worst and where it’s coming from. If you’ve ever made a habit of checking air quality around you, you may notice that there aren’t actually that many monitoring stations, and your closest one may not be that close. For pollution data to really be accurate and helpful, we need a lot more of it.
Luckily, IoT sensors and low-power wide-area networks are making it a lot easier to get and spread ultra-local data. Lampposts are one popular place to put them. For example, the Republic of Korea and Barcelona have already built out a network of pollution sensors in their streetlights.
On the other hand, outfitting (配备) cars, bikes, and even people with pollution sensors provide valuable data on a smaller, more mobile scale.
Since pollutant levels can change dramatically even from one city block to another, having smaller-scale data is important for making a lot of decisions that, over time, might have a major influence on our health and behavior. It can influence where we decide to live, when we exercise, whether we bike to work, and, perhaps most importantly, what we can do about pollution in our area.
All the Internet of Things can help us do on a personal level is use less energy. The data it provides, though, can be used to make big and small changes to the way we behave and build, and that is eventually where we’ll see benefits.

6 . Ninety-seven percent of Earth’s water is ocean. No blue, no green. If you think the ocean isn’t important, imagine Earth without it. Fifty years ago, when I began exploring the ocean, no one realized that we human being could do anything to harm the ocean.
For me, as a woman scientist, it all began in 1953 when I first tried diving. In 1979, by using a submersible, I had a chance to reach the ocean floor which was six miles offshore and 1,250 feet down. Since then, I’ve used about 30 kinds of submarines. We need new deep-diving submersible. We need to see the undersea mountains and understand life in the deep sea. Exploring and protecting the wild ocean is my big wish.
What’s worrying us is that an ice free Arctic Ocean may happen in this century. That’s bad news for the polar bears. Additional CO2 is not only driving global warming, but also changing ocean chemistry, making the sea more acidic. That’s bad news for coral reefs and oxygen-producing plankton(浮游生物). Actually, nearly half of the coral reefs have disappeared. We’re putting hundreds of millions of tons of plastic and other rubbish into the sea. We’re blocking the ocean, poisoning the planet’s circulatory system. Most of the turtles, sharks, tunas and whales are way down in numbers. All of these are part of our life support system.
Health to the ocean means health for us. I wish we would use all means—films, explorations, the web, new submarines—and campaign to stimulate public support for ocean protected areas. My wish is a big wish, but if we can make it happen, it can truly save and restore the ocean, the blue heart of the planet. For the children of today, for tomorrow’s children: as never again, now is the time.

7 . On a boat near Costa Rica, a team of marine biologist is helping a turtle. The animal is having trouble breathing, and the team discovers why—there is something inside its nose. A scientist tries to extract the object, but the turtle cries in pain. Finally after eight long minutes, a long object is pulled out. It is a 10 centimeter plastic straw.
The video of the turtle’s rescue has been viewed millions of times on YouTube. It has helped raise awareness of a growing problem: The world’s seas are full of plastic. Since 2000, there has been a huge increase worldwide plastic production, but we recycle less than one-fifth of it. A lot of this plastic waste ends up in the ocean. Today, scientists think about 8.1 billion kilograms goes into the sea every year from costal regions. Most of this plastic will never break into little pieces.
This ocean plastic hurts millions of sea animals every year. Some fish eat plastic because it is covered with sea plants, and it looks and smells like food. “In some cases, eating sharp pieces of plastic can seriously hurt sea animals and even result in death,” says marine biologist Matthew Savoca.
Plastic is useful to people because it is strong and lasts a long time, but this is bad news for sea creatures who eat or get stuck in it. According to Savoca, single-use plastics are the worst. These are items that are used only once before we throw them away. Some common examples include straws, water bottles, and plastic bags. About 700 sea species have been caught in or have eaten this kind of plastic. Luckily, the turtle survived and was released back into the ocean. How will plastic affect sea animals in the long term? “I think we’ll know the answers in 5 to 10 years’ time,” says an expert from Columbia University. But by then, another 25 million tons of plastic will already be in the ocean.
1. Which of these questions is answered in Paragraph 1?| A．Where was the scientist from? | B．When did the incident take place? |
| C．What was the cause of the turtle’s pain? | D．How did the scientists remove the object? |
| A．Because more plastic is produced than recycled. |
| B．Because sea animals consume plastic. |
| C．Because plastic can be dissolved in the sea quickly. |
| D．Because other places are already full of plastic waste. |
| A．Single-use plastics are people’s favorite. |
| B．The ocean’s plastic problem will be solved in a decade. |
| C．More than 700 sea species can survive the ocean plastic. |
| D．Plastic waste can cause deadly damage to sea animals. |
8 . A Plastic Ocean is a film to make you think.Think,and then act.We need to take action on our dependence on plastic.We’ve been producing plastic in huge quantities.Drinking bottles,shopping bags and even clothes are made with plastic.
The film begins as a journey to film the largest animal on the planet,the blue whale.But during the journey the filmmakers make the shocking discovery of a huge,thick layer of plastic floating in the Indian Ocean.
In the film there are beautiful shots of the seas and marine life.
They present short-term and long-term solutions.These include avoiding plastic containers and recycling as much as you can.The filmmakers also stress the need for governments to work more on recycling programmes.
We make a shocking amount of plastic.Over 300 million tons of plastic are produced every year,and at least 8 million of those are dumped into the oceans.The results are disastrous,but it isn’t too late to change.
| A．This causes them to travel around the world to look at other affected areas. |
| B．Once you’ve seen the film,you’ll realize it is time to do our part. |
| C．It has raised public concern all over the world. |
| D．We live in a world full of plastic,and only a small amount is recycled. |
| E．But the film doesn’t only present the negative side. |
| F．In conclusion,we only have one earth to live on. |
| G．These are contrasted with dumps of plastic rubbish. |
The COVID-19 pandemic (流行病) reduced global greenhouse gas emissions by 7 percent this year, released by the Global Carbon Project on Friday.
“The amount fell by 2.4 billion metric tons
UN Secretary-General Antonio Guterres on Tuesday appealed for ambitious climate action,
10 . Natural gas produces half as much CO2 when burned as coal, but that doesn't make it harmless. Climate scientists say that rising production of natural gas is becoming one of the biggest driving forces of climate change and that plans for industry expansion could stop efforts to make the Earth’s climate steady. The U. S. energy industry plans to spend hundreds of billions of dollars building pipelines and receiving stations in coming years to increase exports of natural gas in supercooled liquefied form, known as LNG(液化天然气).
Climate scientists are concerned about another greenhouse gas that leaks(泄漏) into the atmosphere during natural gas production: methane. Methane has a warming effect up to 80 or 90 times more powerful than CO2 over a 20-year timescale. Many companies say they have been doing more to find and fix methane leaks.
What about gas as a temporary “bridge fuel” to a cleaner future? The industry often describes natural gas as a vital “bridge” to help change from relying on coal-fired power to cleaner sources of energy. Advocates of natural gas argue that gas-fired power plants can provide continuous electricity, backing up wind and solar operations. Climate scientists are increasingly concerned, however, that plans to expand the industry a lot mean that using natural gas as a “bridge” could end up locking the world into a high-carbon and fast-warming future.
