Climate change has already begun to impact our planet in more ways than we can think.

1. Saving the environment starts with us and it is our responsibility to act against these terrible changes to preserve the planet for future generations.

Make your commute green. Millions of people drive to work every day. 2. However, the downside to this is that millions of cars emit greenhouse gases that destroy our atmosphere. There are always other options that you can utilize to make your commute to work eco-friendly. For starters, taking public transportation to work is a great way to cut out emissions. Riding your bike to work is also incredibly helpful to the environment and is a great method to get exercise.

Be more conservative with energy usage. Becoming more energy efficient is a great way to prevent pollution. 3. Make sure to turn off lights and unplug devices that you are not using anymore when you are done with them. Replace your light bulbs with energy-efficient light bulbs to help you save electricity too.

Recycle. Manufacturing plants emit a large number of greenhouse gasses per year. It is unavoidable in the production of goods that we use on a regular basis. However, a cleaner alternative would be to invest in recycling. 4. The professionals will take these items to a processing plant where they will be remade into other recyclable materials again.

5. Focusing your efforts to spread awareness about renewable energy is the best way to create a positive impact in your community. By informing others about how renewable energy is better than fossil fuels (化石燃料), you will persuade others into investing in the idea.

A.Educate yourself and others.

B.Encourage the use of renewable energies.

C.It’s simply unavoidable in our modern-day society.

D.Be sure to collect your abandoned paper, plastic and electronics.

E.Fortunately, there are always things we can do to fight against it.

F.This requires you to cut down on energy usage in your household.

G.Recycling is a cost-effective and eco-friendly process that eliminates waste.

Dangers from Outer Space

What is the greatest threat to life on our planet? Is it climate change? Shortages of food or water? Or might an altogether bigger danger come from somewhere further away: space?

We’re not talking about an attack by little green men here. Instead, how about being hit by a large falling star, beat by deadly universal rays or fried by the energy of an erupting star?

It wouldn’t be the first time that our Earth has had a rough ride over the last 3.7 billion years, with some disastrous events. The most famous mass extinction（灭绝）was 66 million years ago, when it’s widely believed that a meteorite（陨石）killed off the dinosaurs. A 110-mile-wide crater in Mexico with the same geological age supports this theory.

Believe it or not, this wasn’t the worst catastrophe in our planet’s history. That was when 96% of life was wiped out at the end of the Permian period, 252 million year ago. Scientists don’t know for sure why this happened, but any potential explanations carry with them the possibility that similar events could happen again.

Some experts believe that our Sun has a twin star which is too far away to observe directly. This huge sleeping star could twist the paths of orbiting icy rocks and cast them towards the rest of the Solar System.

Is this what happened 252 million years ago? Or is there instead, perhaps, a distant, ninth plant in our Solar System which pulls in passing comets（彗星）and sends them dashing our way?

The Sun that has given us the warmth is gradually turning into a deadly enemy. Like all stars, it is slowing dying, burning through its energy supplies. As it does so, it expands, and in about 2 billion years it will have grown so much that the heat will make life on planet Earth unbearable.

While all this sounds a little horrible, take comfort from the fact that the chance of being hit by a huge interstellar projectile（星际碰撞物）is unbelievably slim, and that 2 billion years is a very long time.

1.When did dinosaurs die out according to the passage?

A. 3.7 billion years ago.　　 B. 252 million years ago.

C. 66 million years ago.　　 D. 2 billion years ago.

2.Why was 96% of life destroyed at the end of the Permian period?

A. The cause is still unknown.

B. A huge falling star hit the earth.

C. A twin star cast icy rocks towards the Solar System.

D. A ninth planet pulled in passing comets.

3.What can we learn from the passage?

A. All stars will eventually run of energy.

B. Our planet will be attacked by little green men.

C. We will be fried by the energy of an erupting star.

D. A huge sleeping star will hit the earth in millions of years.

4.What is the author’s attitude toward the dangers from outer space?

A. Frightened.　　 B. Relieved.

C. Worried.　　 D. Doubtful.

Climate change will bring and has already brought a wide variety of threatening destruction to human existence. Some of these are well-known and already operative, like the wildfires racing along California’s freeways or the permanent droughts that have been upsetting Mediterranean farmers. But are these all terrible disasters we can come up with that are brought about by climate change?

Absolutely not. None of the challenges posed by our warming climate has appeared larger in the popular imagination than sea-level rise, as global populations and wealth are heavily concentrated in low-lying coastal cities. The best available models suggest that 37 million people currently live in places that will be below high tide by 2050-in an optimistic low-carbon-emissions scenario (设想).

Or rather, that’s what such models suggested before this week. On Tuesday, a new study revealed that those alarming statistics were wildly inaccurate. The actual impacts of sea-level rise are going to be much, much worse.

Previous estimates of the impact that rising tides would have on coastal cities relied on essentially a three-dimensional map of Earth obtained from satellite readings. But those readings were fundamentally unreliable because they often measured the planet’s upper surfaces — such as treetops and tall buildings — rather than its ground level. These mistakes led scientists to overestimate the elevation (海拔) of many regions of Earth.

In a new study published by the journal Nature Communications, scientists from Princeton, University detail this methodological problem, then use artificial intelligence to determine the previous literature’s error rate. Their research yields some amazing updates to our conventional understanding of what the next century has in store for our coastlines.

In its optimistic scenario, the Princeton study projects that lands currently occupied by 150 million people will lie below high tide in 2050. But as warming destroys many of the world’s agricultural regions, climate change could accelerate migration from rural areas to coastal cities.

The new study does include one piece of slightly encouraging news. While previous models suggested that 28 million humans currently live in places that already lie below high tide, the actual number is closer to 110 million — which means seawalls and other barriers have proven sufficient to keep many cities dry even as sea levels have risen around them. Still, the scale of barrier construction necessary to save low-lying cities from collapse is now, apparently, far greater than previously understood when the task already looked terribly expensive, particularly for developing countries.

If the Princeton researchers’ projections are correct, avoiding mass death and suffering in the coming decades will require not only rapidly reducing carbon emissions and strengthening construction of seawalls but also furthering mass migrations away from low-lying cities and islands and toward higher ground.

1.The first paragraph is mainly intended to 　　　　 .

A.introduce the topic of this passage

B.show various disasters caused by climate change

C.call on people to fix attention on climate change

D.lay emphasis on the seriousness of climate change

A.it’s cheap to construct seawalls as well as other barriers

B.the scale of barrier construction is much greater than before

C.developed countries have less trouble in dealing with rising sea levels

D.seawalls do have the function to prevent coastal cities being drowned

4.What can be a suitable title for the passage?

Scientists studying the impact of climate change on the Arctic need to consider ways to reduce their own carbon footprints(碳排放量), says Ryan Brook, a researcher who regularly flies north to study the health of caribous(驯鹿).He calls on scientists to show leadership by examining and sharing ways to reduce the impact of working in polar regions.

“The importance of the research is not at question here. It is important to our understanding of and adapting to climate change. But we need to think about better approaches,” says Brook.

“This is an issue for all scientists, though polar researchers often travel particularly long distances using commercial air travel. We also rely extensively on small aircraft, icebreakers, and snowmobiles, all of which produce large amounts of carbon.”

Brook studies the health of caribou herds in Nunavut and Northwest Territories. He works with northern wildlife managers. This work typically takes him north five or six times per year and when he calculated his own carbon footprint, he was not happy with the result.

“My research footprints are about the same as the annual footprints of an average Toronto resident. Basically, I have two footprints — my own personal life, which is moderate, and my research footprint.”

Climate scientists can rightly argue that Arctic research is a specialized field and the community of scientists who travel north is relatively small. Even if all scientists working in the north reduced their carbon emissions, it would not make a big impact on the global scale. For Brook, it’s the option that matters.

There are ways researchers can reduce the amount of carbon they use. Some helicopters use less fuel than others. Solar and wind power are alternatives to gas-fired generators. And while carbon offsets(抵消) don’t reduce the amount of carbon emitted, they are an easy first step.

“There aren’t necessarily any easy answers, but we need to start talking about it,” says Brook. “This is particularly important for the next generation of scientists being trained and I hope to see them become leaders in this issue.”

1.What did Brook find when he calculated his own carbon footprints?

2. Brook’s opinion is challenged by the statement that ________.

3.We can infer from the last paragraph that ________.

4.What’s the main idea of the text?

We already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.

Not long age. My wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is bending up even faster than predicted only a few years ago, and that the consequences could be severe if we don’t keep reducing emissions（排放）of carbon dioxide（CO₂）and other greenhouse gases that are trapping heat in our atmosphere.

We decided to try an experiment. For one month we recorded our personal emissions of CO₂^. . We wanted to see how much we could cut back, so we went on a strict diet. The average US household（家庭）produces about 150 pounds of CO₂ a day by doing common-place things like turning on air-conditioning or driving cars. That’s more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce?

For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man Is Changing the Climate and What It Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting（融化）of the ice sheets in Greenland or West Antarctica. “To stay below that point, we need to reduce CO₂ emissions by 80 percent,” he said.

Good advice, I thought. I’d opened our bedroom windows to let in the wind. We’d gotten so used to keeping our air-conditioning going around the clock. I’d almost forgotten the windows even opened. We should not let this happen again. It’s time for us to change our habits if necessary.

1.Why did the author and his wife try a new diet?

A. To take special kinds of food          B. To respond to climate change.

C. To lose weight                      D. To improve their health

2.The underlined words “tipping points” most probably refer to

A. freezing points       B. burning points       C. melting points     D. boiling points

3.It can be inferred from the passage that

A. it is necessary to keep the air-conditioning on all the time

B. it seems possible for every household to cut emissions of CO₂

C. the average US household produces about 3,000 pounds of CO₂ a month

D. the average European household produces about 1,000 pounds of CO₂ a month

4.Which of the following would be the best title for this passage?

A. Saving Energy Starts at Home

B. Changing Our Habits Begins at Work

C. Changing Climate Sounds Reasonable

D. Reducing Emissions of CO2 Proves Difficult
