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 . We are unavoidably linked to the ocean. Collectively, it covers about 71% of our world and is instrumental in the processes that keep us alive. While the rainforests may be referred to as “the lungs of the planet”, scientists say it’s actually the ocean that provides 50% — 80% of the oxygen we breathe. Besides, through a “conveyor belt” action, it helps regulate Earth’s climate by transporting heat away from the equator, towards the poles to cool. The ocean also proves itself essential in the fight against climate change too. It absorbs 50 times more carbon dioxide than our atmosphere-or rather, it’s not the ocean itself but what lives in it. And perhaps one of the most incredible forms is the humble seagrass.

Across the globe, there are more than 70 species of seagrass, growing in shallow and sheltered coastal areas and covering 300,000 square kilometres, which absorbs 10% of the ocean’s carbon each year and captures carbon up to 35 times faster than tropical rainforests. Seagrass builds its leaves and roots using carbon, which it extracts from water through the process of photosynthesis (光合作用) — and it holds on to it, even after death. Dead plant material decomposes (分解) slowly on the ocean floor, and this means that the carbon stored within is eventually buried under the seabed.

Significant as it is, seagrass is critically endangered. According to the U. N. Environment Programme, a seagrass area the size of a football pitch is destroyed every 30 minutes around the world. Fortunately, restoration missions are already underway, in places as far afield as Kenya, Mozambique, and the UK. But rising temperatures remain a twofold threat: an increase in storms that tear the shallow-rooted seagrass from its beds, and rising sea-levels that block out the sunlight.

However, seagrass is known to adapt to survive-and gene sequencing of the Zostera marina seagrass has shown it has done so on three separate occasions already. Could it be one of Earth’s great survivors that will save us all? Only time will tell.

3 . Last year, brilliant’ botanists from Royal Botanic Gardens, Kew, discovered, identified and named 114 spectacular new species of plants and fungi (真菌) from around the world. Let’s find out more about some of Kew’s most wonderful new finds.

ROYAL MUSHROOM

NAME: Queen’s hedgehog fungus

FROM: Surrey, England

Named after the late Queen Elizabeth II, this rare fungus was found in an ancient forest in White Down, Surrey. According to the scientists who discovered it, the soft, white needles under the fungus’15cm-wide cap look like hedgehogs’ needles — giving it the second part of its name. Cool!

WORLD’S STRANGEST DAFFODIL

NAME: Sternbergia mishustinii

FROM: Turkey

The flowers of this rare species are bright yellow, but they’re only 2cm long and don't open up into a visible flower. Just 300 of these plants have been discovered, secret to hide them from illegal plant collectors.

RECORD-BREAKING WATERLILY

NAME: Giant Bolivian waterlily

FROM: Bolivia. South America

Check out this huge waterlily — its 3m wide leaves are big enough for a kid to float on! The big species has just won three Guinness World Records for largest waterlily, largest waterlily leaf and largest undivided leaf. And get this — although the giant plant was only named last year, a dried sample has been kept in Kew’s own Herbarium since 1845! Botanists had thought it was a similar, related species. Thankfully, the case of mistaken identity is all cleared up now. Unbe-leaf-able!

1. What’s Queen’s hedgehog fungus like?

A．It has yellow flowers.	B．It’s native to England.
C．It looks like hedgehogs.	D．It’s critically endangered.

2. What Guinness record does Giant Bolivian waterlily hold?

A．The oldest fungi.	B．The biggest leaves.
C．The fastest growing plant.	D．The largest waterlily species

3. Where is the passage most likely to have been taken from?

A．A botanical magazine.	B．A geographic textbook.
C．A historical document.	D．Guinness World Records.

4 . The world loves a cup of tea. It only takes a few grams to make a cup of tea and millions of tons of tea are consumed every year. Tea can be good for you because it contains some things that help lower cholesterol and reduce the risk of cardiovascular disease. Tea also contains caffeine(咖啡因), which improves not only mental alertness but can also increase anxiety and cause other problems.

What would be agreeable is a tea plant that provides all the taste and goodness but with little or none of caffeine. Chen Liang and Jin Jiqiang in the Tea Research Institute, Chinese Academy of Agricultural Sciences think they have found just such a plant, growing wild in a remote area in southern China’s Fujian Province. Known locally as hongyacha, the discovered plant grows only between 700 meters and 1,000 meters above sea level around a handful of Chinese villages. As they report in the Journal of Agricultural and Food Chemistry, not only is the tea plant naturally caffeine-free but it also contains a number of unique medicinal compounds that, the locals believe, offer considerable health benefits.

The researchers are now exploring methods to protect hongyacha in its natural habitat while further studies are carried out. It can take time—and sometimes it does not work—for new plant varieties to be bred for commercial use. A pair of naturally caffeine-free coffee plants were discovered in 2003, but little progress has been reported. Tea lovers will be watching hongyacha with interest. And others will wonder what else is out there.

1. What’s the disadvantage of drinking tea according to paragraph 1?

A．It can make people hard to sleep.	B．It can make people feel anxious.
C．It can get people addicted.	D．It can take people much time.

2. What can we learn about hongyacha in paragraph 2?

A．It is nothing but just medicine.	B．It can only survive in greenhouses.
C．It is a good pick for caffeine lovers.	D．It has a good taste and little caffeine.

3. What might the follow-up study focus on about hongyacha?

A．Its future location.	B．Its natural habitats.
C．Its future market.	D．Its production process.

4. Where is the text probably taken from?

A．A health magazine.	B．An advertising brochure.
C．A travel guidebook.	D．A newspaper.

5 . With spring around the corner, stores are offering gardeners many choices for seeds. Starting a garden from seeds, rather than buying young plants, is a low-cost way to enjoy many kinds of flowers and food crops.

    1     Everything the plant needs to start growing is in the seed. All you have to do is put it into soil that is a little wet and not let the soil dry out while the seed does its own job. If there are any special requirements, they are usually printed in the simple directions on the back of every seed container.

Planting big seeds is simple.     2     Put the tip of a pencil in water and then use it to pick up each seed. It will hold one seed as you put it into its starting container.

When choosing containers to start plants, you can use any old plastic containers, newspapers or cardboards.     3     But remember to put drainage (排水) holes in each one. If you do not add holes, water can build up in the bottom and cause the seeds to rot.

Gardeners are reminded to be aware that it would be a shame to grow something in a container and then forget what it is called.     4    

And it is never too early to think about the next growing season. Once you have established plants in your garden, consider letting some “go to seed.”     5     That way you will have your own seeds for next year’s garden, and you will not have to buy them at all.

A．As a matter of fact, starting seeds is easy.

B．In fact, choosing the right seeds is important.

C．You can also use egg containers or anything that is available.

D．You can keep the containers inside your house or under a shelter.

E．This means you are growing them for their seeds, not for crops.

F．But very small seeds, like celery seeds, need a little equipment.

G．Write the names of the seeds on the containers to help you remember.

6 . In recent years, scientists have discovered that mushrooms are much more than just a tasty addition to your favorite dish. In fact, they are the “Internet of trees” — a vast network of underground mycorrhizal (菌根的) fungi (真菌) that connects trees and other plants in a similar way to how the Internet connects people.

The mycorrhizal network is made up of hyphae (菌丝),which connect the roots of different plants and trees. These hyphae act like an underground internet, allowing plants to exchange nutrients, water, and even hormones (激素). For example, if one tree is under stress due to drought or disease, it can send out hormones to warn other nearby trees of the danger. The other trees can then prepare themselves for the coming threat.

Human beings can help trees and mushrooms by practicing “mycorestoration” in regenerative projects. With the Global Tree Initiative working towards reforestation and preserving natural habitats, it is important to share how mycorestoration can supply innovative ways to mitigate the impact of human activities.

Fungi are natural decomposers (分解器) that break down complex organic matter, like dead trees, into simpler compounds that can be absorbed by plants. This decomposition process is crucial for the health of our forests, as it contributes to nutrient cycling, soil formation, and carbon sequestration. By introducing native fungi species into areas where deforestation has occurred, we can help regenerate soil and support the growth of new trees. Fungi form symbiotic (共生的) relationships with tree roots, improving their ability to absorb water and nutrients. This increased access to resources accelerates tree growth and improves their resilience to stress, such as drought or disease.

Fostering sustainable communities through mycorestoration can be conducted through global partnerships that promote ecology within Ecovillage Design Education. The Global Ecovillage Network’s presence in five continents and in over 8,000 communities around the planet, helps the regenerative approach to community building and preservation of existing forests. By promoting sustainable land management practices and reducing our reliance on extractive industries, ecovillages can help prevent deforestation and protect the habitats of countless plant and animal species.

7 . How to create an indoor garden

If you’re looking for a way to brighten up your home, consider creating an indoor garden.     1     We will share some basic tips on how to make yours look its best.

Know the type of plants you want

Deciding is probably the hardest part when it comes to creating an indoor garden because there are just so many plants to choose from. Start by thinking about what type of plants you want.

    2     Or maybe something that doesn’t need much attention or effort? Once you have an idea of the type of plant you want, you can start narrowing down your options.

Get the right potting soil and containers

Now that you know what type of plants you want, it’s time to get the right potting soil and containers. Make sure to get a potting mix that is specifically designed for indoor plants.     3     As for containers, you can really use anything as long as it has drainage holes.

Choose a bright location Once you have your plants and pots, it’s time to choose a location for your indoor garden.     4     This will help your plants grow and stay healthy. If you don’t have a spot that gets a lot of light, you can always use artificial lighting like grow lights.

    5    

In addition to watering, you’ll also need to add substance to your plants about once a month. This will help them grow and stay healthy. Just be sure to follow the instructions on the package. Don’t overdo it.

A．Give fertiliser monthly.

B．How exactly can we make one?

C．Follow the instruction correctly.

D．But don’t worry, we’re here to help.

E．This will help your plants grow strong.

F．Do you want something that will blossom?

G．Look for a spot in your home that gets a lot of natural light.

8 . “A beautiful field of flowers can be a rather noisy place. It’s just that we can’t hear the sounds.” Scientists at Tel Aviv University have conducted a six-year experiment, proving that plants make noise in certain stressful situations.

Plants produce a high frequency (频率) clicking sound, and when short of water, or damaged, the clicks become far more regular. They also made different sounds, depending on whether they were thirsty or injured. “Each plant and each type of stress is related to a specific sound,” said Professor Lilach Hadany, who led the research study.

Focusing particularly on tomatoes, wheat and corn, the plants were placed in a soundproof(隔音的)room and recorded by microphones. Some plants were starved of water, others cut, and a control group was left undamaged. The researchers used an algorithm (算法) to separate the noises, suecessfully telling the difference between the sounds depending on whether they were dry or cut. The algorithm did this in a greenhouse setting which included far more surrounding sounds, but it was still able to recognize the particular cries for help of the plants.

On average, the human ear can hear sounds up to around 20kHz, while the sounds produced by plants are in the 40-80kHz region, far beyond our hearing. “The sounds made by plants can’t be heard by humans but can probably be heard by various animals, such as bats, mice and insects,” Hadany tells us. Though this has yet to be proven, it’s possible that these creatures use this information to choose which plants to eat.

A study led by Reda Hassanien of China Agriculural University in Beijing years ago, also proved that plants reacted to sound waves, with some plants greatly increasing their yield. While evidence shows that plants can react to sounds, there’s no evidence today that they can actually hear them.

1. What can we know from the six-year experiment?

A．Plants of different types make the sound of the same frequeney.

B．Plants produce more regular sound in certain stressful situations.

C．Plants make sounds with a much lower frequency when stressed.

D．Plants make the sound of the same frequeney whatever the situation.

2. What is the algorithm used for in the research?

A．To record the sounds.	B．To control the sounds.
C．To produce the sounds.	D．To identify the sounds.

3. What has been proven by scientists according to the passage?

A．Plants can hear each other’s cry for help.

B．Animals can hear the sounds made by plants.

C．Plants can make sounds and respond to sound waves.

D．Animals decide what to eat based on the sounds plants make.

4. Which of the following is the best title of the text?

A．Sounds That We Can’t Hear

B．Beautiful Songs from Plants

C．Plants React to Different Types of Stress

D．Plants Talk, Especially When Stressed

9 . Plants and exposure to greenery have been found to have multiple mental health benefits, such as lowering stress, decreasing feelings of depression, increasing sociability, restoring focus, improving cognitive performance, improving mood, and increasing self-esteem.

Gardening and care for plants can help to turn people away from negative thoughts or emotions. So with all that, what do these experts recommend as the best plant?

Snake plant. It’s very easy to care for, thrives in spaces with low sunlight, has visual appeal, and cleans the air, and they are drought resistant if you forget to water them.

Spider plants. Spider plants, with plenty of light-green leaves, are another low-maintenance selection.When a spider plant thrives, it will grow new offshoots that can be clipped and potted as a new plant.

Aloe Vera. Drought-resistant and easy to grow. Aloe Vera is low-maintenance, you can just water it monthly, and it helps clean the airspace and is helpful for burns, cuts, and scrapes to help injuries heal faster or soothe pain.

Lavender is well-known for its relaxing scent, and it has a calming effect, aids in reducing stress, promotes sleep.This means it’s great both in the garden, or clipped and dried in a bowl inside your space .

Basil is a summertime herb that loves the sun. Not only is it delicious in meals, but eating basil has health benefits, too. It has properties which help to relieve stress and anxiety.

Lemon balm. This fragrant green herb is part of the mint family and is simple to cultivate.
