1 . In a Parisian old shoe factory on the city’s outskirts, a new kind of life is taking root. Neoplants, a startup from Paris, has developed a special houseplant that could potentially help improve indoor air quality by removing harmful pollutants.

The plant is a modified variety of one of the most popular and low-maintenance houseplants. Its DNA has been altered to enhance its capacity to absorb volatile organic compounds (VOCs) from the air we breathe inside our homes. These VOCs include substances like formaldehyde, benzene. toluene. ethylbenzene, and xylene, which are commonly found indoors and can be harmful in large quantities.

The genetic tweaking also allows the plant to convert the absorbed VOCs into substances it can use. such as sugars and carbon dioxide, which then fuel its growth. While Neoplants’concept is quite promising, proving its effectiveness is a challenge.

Plant shops often claim their greenery can purify the air, but much of this belief stems from research conducted by NASA back in 1989. They found that houseplants could indeed absorb certain toxins. However, achieving the same level of toxin removal as simply opening a window would require an impractical number of plants   — anywhere from 10 to 1,000 per square meter.

So, does Neoplants’genetically modified houseplant offer a better solution? Field tests haven’t yielded definitive results yet, but there is hope for more conclusive testing in the future with the help of a new lab equipped with unique non-absorbent rooms that mimic real-life conditions . Additionally, the company is exploring potential applications for its gene-editing technology in areas such as carbon capture and phytoremediation, where plants are used to clean up contaminated environments

Neoplants is relying on patience and a bit of faith. It takes time for innovations to mature. “This will be the first time such a product exists.” says the company’s CEO. drawing a parallel to the early days of computers, which were not very powerful initially but still represented a significant breakthrough.

With Neoplants’ vision, the old shoe factory on the edge of Paris isn’t just a place where shoes were made; it’s where a novel approach to cleaning our indoor air is being cultivated — one that could someday make our homes healthier and more environmentally friendly.

2 . Pacific Coast Range

Stretching along the west coast of North America from northern California to Alaska, the forests found along the Pacific Coast Range are the largest area of temperate (温带的) rainforest in the world. The forests are home to the coast redwood, the world’s tallest tree. Across the region, the forest understory (林下叶层) is wet and heavily vegetated.

Taiheiyo Evergreen Forests

Found in southern Japan, they are temperate rainforests of evergreen broadleaf trees. The forests can receive more than 100 inches of rain every year. The forests are covered by Japanese cedar and Japanese stone oak, while moso bamboo comprise the understory. The extent of the Taiheiyo forests has been reduced due to development and agriculture. Today,17%of the remaining forest is protected by national parks and other reserves.

Atlantic Oakwood Forest

The Atlantic Oakwood Forest covers the wettest parts of the United Kingdom. A species of oak tree (橡树) called sessile oak occupies the landscape. Unlike other temperate forests, these forests tend to have an open understory of grasses. Much of the historical range of the forest has given to agriculture and other development, though that has changed in recent decades.

Valdivian Temperate Rainforest

This forest is found on the west coast of Chile and Argentina, on the wet, western slopes (斜坡) of the Andes mountain range. With the coastline to the west, the peaks of the Andes to the east, and the Atacama Desert to the north, the region supports a number of plant and animal species found nowhere else in the world. Uniquely, the forest is covered by evergreen flowering trees, which are native to Chile and little known outside the region.

5 . Madagascar, the world’s second-largest island country located off Africa’s eastern coast, is an island of diverse ecosystems and a biodiversity hotspot. The country has unique wildlife, with 90% of its plants and animals found nowhere else. Madagascar’s wildlife creates some of the country’s most beautiful scenery and popular spots. One of its conspicuous landscapes, attracting tourists from almost all corners of the Earth, is the Avenue of the Baobabs in the Menabe region. This avenue is made up of numerous baobab trees along the dirt road linking Belon’i Tsiribihina and Morondava, creating a unique and beautiful setting.

Baobab trees are common throughout Madagascar. Of the Earth’s eight species, six are native to the country. Some of the baobabs in the country are about 2, 800 years old, with trunks rising to 150 feet. The avenue is a row of about 25 baobabs stretching about 260 meters. Other baobab trees are also found in the nearby pastures (牧草地). This road is one of Madagascar’s most visited places. It is also the most accessible place to see some of Africa’s oldest baobabs. These trees were once part of a forest that was made up of other plants. However, massive deforestation cleared the area of most trees, leaving the baobabs to grow alone.

The baobab trees along the road and the other species growing in the nearby areas are always under constant threat from the increasing population. The trees also face threats from polluted water from the nearby fields, forest fires, and bushfires. Despite being a popular tourist attraction, the Avenue of the Baobabs has no admission fee or visitor center and generates little money for local communities.

Thankfully, non-governmental organizations in partnership with the government have noticed the area and developed activities to protect the avenue. The Ministry of Environment, Ecology, and Forests declared it a temporary protected area in July 2007. In July 2015, the site was declared a national monument (国家保护区), the first in Madagascar. The government and local communities hope the trees can survive for additional 800 years.

6 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Indoor plants are a beautiful way to    1    (bright) up your home, especially in the gray    2    (month) of winter. But there can be a dark side to houseplants if you have children or if children visit your home. It is important that you know which plants are poisonous to children.

Gardening expert Jessica Damiano    3    (recent) wrote about the issue for The Associated Press. She said she often pointed out houseplants in homes that should     4    (keep) out of children’s mouths. Last week, Damiano    5    (visit) her cousin’s home and saw a Dieffenbachia plant in the kitchen. Her cousin told her that her young son,    6    had just begun crawling, had shown interest in     7    leaves. Damiano had to explain to her cousin that eating a small amount of the plant’s stem could cause temporary     8    severe pain. The plant parts can cause throat and mouth swelling. The plant’s sap can cause nose, skin and eye pain. Damiano wrote that parents should teach their young children not to put non-food plant parts into their mouths. “Parents should also educate     9    (they),” she said. She urged parent store search whether the plants in their homes are safe to grow around children. She also suggested     10    (learn) the official botanical names of any houseplants so that they can be able to provide that information quickly to a poison control expert, if needed.

And China is     9     (will) to contribute to global food security and calls for joint efforts to end global hunger and poverty.

It     10     (believe) that Yuan’s dream will come true one day.

8 . Burning coal for energy adds planet-warming carbon dioxide(CO2) to Earth's atmosphere. As the planet heats up, experts warn that simply cutting greenhouse gas emissions（排放） will not be enough to avoid global warming. CO2 must also be remcved from the atmosphere.

Existing experimental machines that pull CO2 directly from the air are too expensive to be widely used. But a new effective technology to remove CO₂ already exists. It is not expensive and easy. It is forests. Planting trees and watching forests are effective ways to clean the air.

Forests used to cover large areas of the Appalachian Mountains in the eastern United States. In the state of West Virginia, coal mining left the land there bare, without trees. Over the years, coal mining and cutting forests took over 90 percent of the red spruce（云杉） forests.

Chris Barton works for the University of Kentucky. He started a group called Green Forests Work, aiming to put trees back on the roughly 400 , 000 hectares of land.

However, Barton explains the land has problems. "If you planted trees on these places, they just didn't grow. The ground was too hard. Water didn't infiltrate（渗透）. The trees can't root. Oxygen can't circulate in those environments. "Using heavy equipment, workers tear the ground. In this way, the trees put down roots.

Barton says not everyone believes the solution is a good idea. "We've had a lot of doubtful look at us twice from people. But after we do it, there's no question that it was the right thing to do. "And it has worked. Forests are coming back to the grounds.

Scientists say that, in West Virginia alone, restoring red spruce forests to the area could send what is equal to 56 million barrels（桶）of oil into the ground. But it will take time—a long time. Around the world, experts say, nature offers powerful tools to fight climate change. But patience is needed. Nature works, but slowly, in its own time.

1. What is the economical and effective way to remove CO₂ from the air?

A．Inventing new and powerful machines.

B．Cutting greenhouse gas emissions.

C．Making use of natural gases instead of coal.

D．Planting trees and protecting forests.

2. What does the underlined word "tear" in paragraph 5 probably mean?
