The second little pig was unlucky. He built his house from sticks, which was blown away by a wolf. His brother, by contrast, built a wolf-proof house from bricks. The fairy tale could have been written by an agent for the construction industry, strongly favoring brick, concrete and steel. However, in the real world it would help reduce pollution and slow global warming if more builders copied the wood-loving second pig.

No other building material has environmental credentials (认证信息) as exciting and overlooked as wood. The energy required to produce a laminated wooden beam (层压木梁) is one-sixth of that required for a steel one of comparable strength. As trees take carbon out of the atmosphere when growing, wooden buildings contribute to negative emissions by storing the stuff. And for refitting older buildings to be more energy efficient, wood is a good insulator (绝缘体). A softwood window frame provides nearly 400 times as much insulation as a plain steel one of the same thickness and over a thousand times as much as an aluminium (铝) equivalent.

But such bigger stories are still uncommon. Governments can help push the industry to use more wood, particularly in the public sector — the construction industry’s biggest client. That would help wood-building specialists achieve greater scale and lower costs. Zero-carbon building regulations should be altered to take account of the emissions that are presented in materials.

Construction codes could be regulated to make building with wood easier. Here the direction of travel is wrong. Britain, for instance, is banning the use of timber on the outside of tall buildings after 72 people died in a tower fire in London in 2017. That is a nonsense. Grenfell Tower was covered in aluminium and plastic, not wood. Modern cross-laminated timber (交叉层叠木板) panels perform better in fire tests than steel ones do.

Carpentry alone will not bring the environmental cost of the world’s buildings into line. But using wood can do much more than is appreciated. The second little pig was not wrong, just before his time.

1. The purpose of the writer telling the story in the first paragraph is to _______.
A.attract the readers’ attentionB.make the argument more convincing

A.To encourage the construction industry’s biggest client to use more wood.
B.To transform Zero-carbon building regulations.
C.To arouse the public’s awareness of protecting the woods.
D.To regulate the Construction codes.
4. The author may imply that _______.
A.the second pig in the tale was unlucky
B.the outside of tall buildings Grenfell Tower could have been constructed in wood

【推荐1】Illegally traded endangered species that escape, forming secondary populations, offer hope to their long-term survival, a study suggests. "This first came to my attention when I read a news story about the seizure of an illegal shipment of 23 yellow crested cockatoos (小葵花凤头鹦鹉),” said Luke Gibson, a college teacher. He learned that the species was critically endangered, which surprised him.

This encouraged Dr. Gibson and his colleague to investigate (调查) how a critically endangered species had become self-sustaining outside of its natural range. They discovered 49 cases of a globally threatened species becoming established as a separate population, which they hadn’t thought of, including the yellow-crested cockatoo in their city.

“This is a species which is primarily threatened by wildlife trade,” he told BBC News. “Poachers (偷猎者) go out into the forest in its native range in eastern Indonesia and capture the bird and then ship them off, usually up to our city where there is a strong demand for pet birds. This is what has fueled the decline of this species in its native range. But it’s really interesting because that same cause also had another effect: some of the people who were keeping this species here accidentally or intentionally released them.” As a result of enough of the birds set free, it allowed a new self-sustaining population to be established in this city.

The government in of Dr. Gibson’s city has made it illegal to capture the species, even though it is a non-native species. Because the city is affluent and relatively well educated, the cases of people breaking the law are extremely rare, explained Dr Gibson, unlike in its native range in Indonesia, where capturing birds form a major source of income.

However, there can be downsides (缺点) to the newly established population of endangered species, such as a limited genetic pool, and suffering from novel diseases. It did also present a possible “very interesting” opportunity for conservationists, Dr. Gibson suggested. This would involve “harvesting” some of the newly established secondary population, which may provide a way to help slow global biodiversity loss.

1. What was beyond Gibson’s expectations according to the first paragraph?
A.The high rate of wildlife trade.B.The preciousness of the birds.
C.The fact that the birds nearly disappear.D.The news that the birds were poached.
2. What happened unexpectedly when the birds were shipped abroad?
A.They formed a separate population.B.They were kept as pet birds.
C.They were traded illegally.D.They were killed for research.
3. Which can replace the underlined word “affluent”?
A.Peace-loving.B.Rich.
C.Free.D.Environment-friendly.
4. For what purpose did the author write the passage?
A.To appeal to everyone to stop the wildlife trade.
B.To explain the challenge the wild birds are facing.
C.To introduce a creative approach to wildlife conservation.
D.To raise peopled awareness of protecting endangered species.

文章大意:这是一篇说明文。近年来,许多美国公司都支持一种潜在的气候解决方案,即碳捕获和储存,政府也以数十亿美元的税收优惠和直接投资来支持它。文章主要说明了美国林务局提议修改规定,允许将二氧化碳污染储存在国家森林和草原之下,文章列举了一些人对此做法的不同看法。

【推荐2】In recent years, lots of American companies have gotten behind a potential climate solution called carbon capture and storage, and the government has backed it with billions of dollars in tax preferences and direct investments. The idea is to trap planet-heating carbon dioxide from the smokestacks of factories and power plants and ship it to sites via thousands of miles of new pipelines. Communities nationwide are pushing back against these pipeline construction and underground sites, arguing they don’t want the pollution running through their land.

Now the U. S. Forest Service is proposing to change a rule to allow storing this carbon dioxide pollution under the country’s national forests and grasslands. “Authorizing carbon capture and storage on National Forest System (NFS) lands would support the Administration’s goal to reduce greenhouse gas emissions by 50 percent below the 2005 levels by 2030,” the proposed rule change says.

Some experts, like June Sekera, a research fellow with Boston University, question the timing of the proposed rule change, given community pushback across the country to pipelines planned on private land. Yet she says the Forest Service proposal to open up national parks for CO2 storage is “an end run around local towns and counties. And it’s a much simpler and way less expensive route.”

In an email, Scott Owen, press officer for the Forest Service, writes that the proposed rule change would allow the Forest Service to consider proposals for carbon capture and storage projects. He writes that any proposals must still pass through a secondary screening, adding, “The Forest Service has been ‘screening’ proposals for use of NFS lands for over 20 years as a means to be increasingly consistent in our processes and also be able to reject those uses that are inconsistent with the management of the public’s land. ” He notes the Forest Service currently does not have any carbon capture project proposals under consideration. The Forest Service has opened public comments on the proposed rule change until Jan. 2, 2024.

1. What does the Forest Service intend to do by changing a rule?
A.Answer the appeals of communities.B.Provide legal space for carbon storage.
C.Enlarge national pipeline storage capacity.D.Loosen tax burden on American companies.
2. What does the underlined phrase “an end run” in paragraph 3 probably mean?
A.An eventful act.B.A desperate try.
C.An alternative way.D.A breathtaking race.
3. What can we infer about carbon capture project from the last paragraph?
A.It is still up in the air.B.It is dead in the water.
C.It is widely recognized.D.It is far from satisfactory.
4. What does the text mainly talk about?
A.A fruitful research.B.A timely rule change.
C.An authorized project.D.A controversial proposal.

【推荐3】Most of our everyday plastic items end up in landfill, left to rot away for many years. But some of it blows away, spoiling the countryside and causing damage to the natural environment and harming wildlife. The problem is most severe in our oceans. Research has found a deserted island in the South Pacific is littered with the highest density (密度) of plastic waste anywhere in the world.

The study described how remote islands act as a ‘sink’ for the world’s rubbish. They become collecting points for fishing items and everyday things including toothbrushes, cigarette lighters and razors-things that we throw away. Dr Jennifer Lavers from the University of Tasmania says “Almost every island in the world and almost every species in the ocean is now being impacted one way or another by our waste.”

This highlights the potentially deadly effect of our disposable (用后即丢弃) culture. When we throw something away, it doesn’t just disappear, it goes somewhere and because of the nature of plastic, it takes a long time to rot away and stays there causing great damage to the ocean’s ecology (生态). And worse still, plastic is broken down into tiny particles over a long period by the wind and the waves, then sea creatures at the bottom of the food chain swallow them. These creatures are eaten by the fish that we eventually consume.

The solution to this problem would be to use less plastic. Several countries now charge for using plastic carrier bags which reduces the amount used and some products now use natural and recyclable materials.

1. What does the author really want to tell us in the first parapraph?
A.It is a good idea to end plastic items in a landfill.
B.Plastic items blow away easily in the strong wind.
C.It is a bad habit to throw away plastics everywhere.
D.Plastic pollution in oceans is a most serious issue.
2. What does the author mean by saying the islands act as a ‘sink’ for the world rubbish?
A.The islands begin to sink with much rubbish on them.
B.The islands have become gathering places for rubbish.
C.The islands are ideal places to hide the plastic products.
D.The islands are inaccessible due to the white pollution.
3. What does the underlined word “This” in Paragraph 3 refer to?
A.Impact on sea species.B.Thrown-away rubbish.
C.The nature of plastic.D.The ocean’s ecology.
4. What’s the really frightening fact about the plastic pollution in oceans?
A.Breaking the balance of ocean ecology.B.Causing many sea creatures to die out.
C.Presenting potential risks to our health.D.Cutting off the food chain of sea creatures.
