1 . Fungi (真菌) play an important role in ecosystems, are a source of food, and make key contributions to the world of medicine.     1    

An estimated two million fungal species — more than 90% of all fungi — have yet to be described by science, according to a science reporter.     2     Scientists are trying to find out more about this largely unexplored world, but it is challenging. Dr Martyn Ainsworth, a senior researcher from Royal Botanic Gardens, Kew, in London, says, “We can grow a certain number in the lab.     3     This has held back a lot of research.”

    4     “A lot of people are afraid of poisonous mushrooms,” says Dr Jassy Drakulic, a plant pathologist, “but only a very small proportion of the thousands of species of fungi in the world can cause disease.” Most are harmless and often beneficial, called by some “the hidden helpers of our environment”. Some fungi provide food and shelter for wildlife, help plants absorb water and nutrients and recycle waste and dead matter. Other types of fungi grow on the roots of trees and plants, forming a huge underground network that helps nourish trees.     5    

So, next time you add mushrooms to your dinner, take a painkiller for a headache, or go for a walk through the woods, remember to thank the living things that made it all possible — fungi.

A．Are mushrooms a type of fungus?

B．So, why do we know so little about them?

C．Wetlands are important because they provide food and shelter for wildlife.

D．The fact that we know so little about fungi leads us to misunderstand them.

E．“Fungi are really the behind-the-scenes team doing all the work,” adds Dr Ainsworth.

F．But there is a whole host of fungi that we cannot grow in the lab.

G．In the UK, there are around 25,000 species of fungi — five or six times more than plants.

2 . 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.

1. What does Neoplants’genetically modified houseplant aim to do?

A．maintain its capacity easily	B．absorb VOC’s massively
C．alter its DNA completely	D．fuel its growth quickly

2. What can be inferred from this passage?

B．Opening a window can remove the same level of toxins as the Neoplants.

C．Neoplants will need powerful computers to make a significant breakthrough.

D．Conclusive testing needs conducting to achieve definite results.

3. What does the underlined term “phytoremediation” in paragraph 5 most likely mean?

A．The process of using plants to absorb nutrients.	B．The process of using plants to purify the air.
C．The process of using plants to explore applications.	D．The process of using plants to edit certain genes.

4. Where is the text probably taken from?

A．Science fiction.

3 . Four Best Plants to Give as Gifts

Choosing a gift for someone is always a challenge. Giving plants is one way to try if the recipient is already a plant-lover. Here are some sure to impress as thoughtful gifts.

Jade Plant

The jade plant is a large succulent (肉质植物) that makes a perfect gift for someone who’s mastered parenting succulents. With a woody stem (茎), it looks like a tree once growing tall enough. Besides occasional watering and a bright window, the jade plant has few other requirements. A good challenge for ambitious owners is to regularly cut off its heavy leaves to reduce weight.

Christmas Cactus

This is a succulent with eye-catching flowers that appear in winter. You might assume it a picky plant, but nothing could be further than the truth. It prefers bright, indirect light and grows well in average potting soil. This plant prefers a steady watering schedule, especially in winter. To encourage more growth, plant it in a hanging container that allows its branches to hang down.

Paperwhite

Some people just aren’t interested in keeping houseplants around long-term, and paperwhite flowers are an excellent gift for anyone you know who fits this mould. Paperwhites grow from bulbs (鳞茎) and will produce flowers out of season. The roots need to be kept relatively damp, but once they are blooming (开花), there’s not much that can go wrong. They can be replanted outside after they have run their course.

Corn Plant

The corn plant is forgiving of variable light conditions and watering routines. It grows slowly, but can reach a height of four to six feet, and can make an impressive floor plant. Its leaves turn paler in direct sunlight to reflect the extra light, and darker green in shady conditions to maximize sunlight absorption.

1. Which plant requires practised gardening experience?

A．Jade plant.

B．Christmas cactus.

C．Paperwhite.

D．Corn plant.

2. How can we help a Christmas cactus grow well?

A．By replanting it outside before blooming.	B．By watering it regularly during blooming.
C．By cutting off most of its heavy leaves.	D．By making its branches grow upwards.

3. What affects the colour of leaves of a corn plant?

A．The frequency of watering.	B．Its flowering time.
C．Its rate of growing.	D．The amount of sunlight.

Nature’s Lungs

We know that trees are nature’s purifier (净化器): They absorb carbon emissions (碳排放)and release oxygen. But their     1       (able) to do that changes as they age. According to Newsweek, trees     2       are at least 20 years old can absorb carbon better than younger ones and older ones. And a recent study by researchers from South Korea’s Forest Research Institute     3       (find) exactly how much carbon that each 25-year-old cherry tree can absorb: 20 pounds (9.1 kilograms) each year.

According to the study, there are     4       (current) about 1.5 million cherry trees in South Korea, which means they can take in as much as 13,650 tons of carbon each year.

This may sound like a lot,     5       it’s only the annual emissions of 6,000 cars. And it’s pretty     6       (shock) if you think about it: The annual emissions of a single-car requires 250 mature cherry trees to absorb     7       carbon.

Yet, planting trees is still considered the most effective way     8       (reduce) global warming, according to Professor Tom Crowther of the Swiss university ETH Zurich. “Forest restoration isn’t just one of our climate change     9       (solution), it’s the top one,” he told the Guardian. “What blows my mind is the scale. I thought restoration would be in the top 10, but it is much    10     (powerful) than all of the other climate change solutions proposed.”

5 . Indoor plants might look as if they just sit around not doing much, but in many ways they are the unsung heroes of the home.     1    , but studies have shown that they can promote people’s wellbeing by improving their mood (心情), reducing stress and helping their memory. What’s more, indoor plants are easy to look after and are not very expensive.

What are indoor plants?

Indoor plants, also known as houseplants or pot plants, are plants that like to grow indoors. Many of these species (物种) are not ideally suited to growing outside in the UK, especially in the winter.     2    .

Why are indoor plants good for you?

Will Spoelstra, who works at the Royal Botanic Gardens, says, “    3    . I find during the winter months, plants around the house can really lift your mood.” Several studies have backed this up and found that indoor plants can improve creativity, focus and memory. There is also research showing that pot plants can clean the air around them by removing harmful gases, such as carbon dioxide. They also remove some harmful chemicals from paints or cooking.     4    .

Which plants can you grow?

Aloe vera, peace lilies and spider plants are some of the species that are easy to grow indoors. You can buy plants from supermarkets, garden centres or online. Younger plants are often cheaper than fully grown ones, and you get to care for them as they mature — which is part of the joy of owning plants. “    5    ,” Spoelstra says. “It can bring a new interest and focus into people’s lives and help to make the link between home and nature.”

A．All plants are different

B．Not only do they look beautiful

C．There are many benefits to growing plants indoors

D．Instead, they grow better inside, where it is warmer

E．Plants like peace lilies and devil’s ivy are among the best

F．Changing the pot of your plant from time to time will also help

G．Learning about the requirements of each plant can be very rewarding

6 . You don’t have to brave the crowds at the Tidal Basin to enjoy the glories of cherry blossom (樱花), which always runs for one month. The delicate pink and white blooms decorate the district. Washington-based nonprofit Casey Trees has a detailed map of where to find them.

Using the map’s explanation, you can check out a neighborhood’s list of trees. The map is color-coded by a variety of cherry blossom, and there are several: Yoshino, Okame, Oshi-ma, and Sour Cherry, just to name a few.

Michaila Musman, the Geographic Information Systems manager at Casey Trees，suggests tracking down the Sargent Cherry, which develops pinkish white blossoms and is called the “cream” of flowering cherries by the Arbor Day Foundation. “They can also support bird species around the city, which is a wonderful bonus.” says Musman.

The map is an annual tradition at Casey Trees. The organization plans to use it to help protect Washington’s trees. To build the map, staff and volunteers walked into the city’s parks to identify and measure every tree they came across. “We can do better advocacy and tree protection if we know what our trees across the city look like.” said Musman.

Other data points for the map come from DDOT’s Urban Forestry Division and from cherry trees that Casey Trees has planted. Most of the trees on the map are located on public land. So if your yard or your neighbor’s yard is the proud home of a cherry tree, it may not appear (considering it as your own secret garden).

And if you miss the cherries this time around, the organization also maintains a separate map of all the flowering trees in the city. Musman recommends checking out the Eastern Red bud. “They are native to this area and they have very beautiful blossoms.” she says, “It seems as though they came right out of a Dr. Seuss’ book.”

1. What can the map be used to do?

A．Research bird species.	B．Decorate some districts.
C．Locate cherry blossom.	D．Identify the type of flowers.

2. Why does Casey Trees develop the map?

A．To know the city better.	B．To protect the local trees.

A．The map comes out of a Dr. Seuss’ book.

B．The map is the only product of Casey Trees.

C．Casey Trees has planted many trees across the USA.

D．Casey Trees takes individual privacy into consideration.

4. What may be the best title for the text?

A．Casey Trees likes cherry blossom	B．Casey Trees will introduce a new map

His hybrid rice research has been     6     (entire) saving millions of people from hunger. Yuan’s dream was     7     (solve) the global food shortage and promote hybrid rice around the world. China has achieved     8     great wonder, feeding nearly one fifth of the world’s population with less than nine percent of the world’s total land. 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 . Seen any unseasonably early daffodils（水仙花）showing their faces yet? UK spring flowers are opening nearly a month earlier than they did before the mid-1980s, due to climate change.

That is the conclusion of a study of nearly 420,000 observations of the first flowering date of 406 plants from a UK citizen science project called Nature's Calendar. It has records dating back to 1753 from gardeners and naturalists, as well as bodies such as the UK's Royal Meteorological Society.

UIf Buntgen at the University of Cambridge and his team found that plants were opening their flowers 26 days earlier on average in the years after 1986 than they did before. They picked that year as it was the mid-point in the data set-where they had about the same number of observations before and after-because there were many more recent records than earlier ones.

The analysis included records of all plants, whatever time of year they flower, but most of them(like the daffodils) bloom in spring. “It is likely that the influence of climate change will be greater for spring-flowering plants, where the usual beginning of warmer temperatures that would cause flowering starts earlier,” says a spokesperson for the UK's Royal Horticultural Society.

There was a bigger advance in the dates of the first blooms for smaller plants, with those less than 20 centimeters high flowering an average of 32 days earlier in the years after 1986 than they had historically.

In any year, flower opening times were closely connected with the average temperature of the months from January to April. “If it's warmer, it's an earlier beginning. If it's cooler, it's a later one,” says Buntgen. The average maximum temperature across those four months rose by 1.1℃, comparing the period from 1950 to 1986 with the years after 1986.

“The change could hurt insects, birds and other wildlife that has evolved to sync with（同步）the flowering of certain plants,” says Buntgen.

10 . 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，并将答案填写在答题卡上。

It tastes like flower. It smells like a campfire. What’s it? It’s a bottle of Petrus Pomerol wine that spent a year on the International Space Station.

In the past few months researchers in Bordeaux     1     (examine) many times the twelve bottles of wine and 320 pieces of grapevines (葡萄藤) that returned to Earth in January. The wine and grapevines are part of a longer-term effort to make plants on Earth     2     (well) resist climate change and disease.

Each bottle     3     (keep) inside a special steel container during the journey. At a special tasting this month, 12 wine experts tried one of the space-traveled wines. They tasted and smelled the wine alongside a similar bottle from the same year     4     had stayed on Earth.

Nicolas Gaume is head of Space Cargo Unlimited, the company     5     (arrange) the experiment to study the effects of the lack of gravity     6     the wine and vines. He said the wine that remained on Earth tasted a little younger than the one that had been to space.

The small pieces of vines,     7     (acknowledge) as canes in the grape-growing business, not only survived the journey but also grew faster than vines on Earth.     8     were unaffected by limited light and water. Once researchers understand why this happened, that could help scient its develop stronger, healthier vines on Earth. Such     9     (inform) could also help create away to grow grapes or to make wine in space.

The research is a good thing for the industry, but it would take a decade or more to lead to     10     (practice) uses.
