1 . Recent research confirms what our farming ancestors have known for centuries about hedges (树篱). They conserve precious soil by acting as windbreaks and absorbing rainwater that would otherwise wash it from the fields. And hedges store carbon, putting them in the front line of our bi d to tackle the climate crisis.

However, hedges have had a tough time in the poor countryside, with farmers encouraged to tear them down in pursuit of maximum production and larger field s to accommodate ever-larger machinery. What’s more, some hedges have been ignored. If left to their own devices, they’ll eventually become a line of trees. Some hedges each year lose their structures and fail to fulfil the primary duty as a barrier. Around a half of the nation’s hedges have disappeared in the past century.

There are signs that “the tide is turning”. The search for net zero has aroused many organizations’ interest in the humble hedge’s role as a carbon sink. The Climate Change Committee is recommending a 40 percent increase in hedges: an additional 200,000 km. Such recommendations are starting to drive policy. Cash-pressed farmers will be encouraged to create new hedges and improve their management of existing ones under the new Environmental Land Management Schemes, which will replace many of the existing agricultural support payments in coming years. Meanwhile, initiatives such as Close the Gap, led by the Tree Council, is providing funding and support to plug the gaps in existing hedges with new planting. There’s even an app to help time-pressed farmers do a quick survey to spot where their hedges need some help.

This is a good time for hedges. Take some of the most pressing challenges facing the countryside, and indeed, the world as a whole — the climate crisis, soil erosion (侵蚀), insect attack and wider biodiversity loss — and hedges are part of the solution.

Scientists in Florida have     1     (successful) grown plants in moon soil collected during NASA’s Apollo missions (任务) in the 1960s and 1970s.

    2     NASA-supported study at the University of Florida used soil collected by astronauts    3     (grow) Thale Cress 2 (拟南芥). To compare results, plants were also grown in Earth soil    4     was made to be similar to moon soil. The researchers     5     (add) water and then seeds to the soil, as well as daily nutrients (营养物). After just two days, their growth started.

According to Professor Anna-Lisa Paul, all the plants looked the same     6     the sixth day. After the sixth day,     7    , it was clear that the plants growing in moon soil were not as healthy as those growing in Earth soil.

DNA testing showed that those Thale Cress 2     8     (plant) in the moon soil were under stress. It was also found that the plants grew in different ways in soil from different parts of the moon. The soil collected during the Apollo 11 mission had been on the moon’s surface several billion years     9     (long) than the other soil, and the plants grown in it were the weakest.

NASA Administrator Bill Nelson believes this research will help future space missions and that resources on the moon and Mars     10     (need) to develop food for astronauts living and working in space.

3 . If the plant could thrive (茁壮成长), maybe I could too, even with cancer.

After my cancer diagnosis (诊断), my friend gifted me a lucky bamboo plant in a deep-green pottery bowl. Despite my physical limitations, ______ the green plant became an achievement during a time when I felt ______.

As a family physician used to ______ care, now I was the one relying on others. The _________ change left me feeling unsettled. Watering the plant, as small an act as it was, ____me to my old identity and taught me I could still be a caregiver and be ______.

Through surgery, radiation, and chemotherapy (化疗), I ______ looking after the plant, and it thrived, so did my ______.

But then, ______, its leaves kept browning and dropping to the floor. The ______of its struggles made me frustrated and uneasy. I seemingly related its struggle to my own health, fearing it ______ the return of my tumor (肿瘤).

As my anxiety eased, I ______ guidance online to figure out how to better take care of the poor little thing. Following the   ______ found, I transplanted it to a larger pot, allowing more room and nutrients it required. When it returned to the sunny window, we both began to thrive again!

Now, the lucky bamboo was not just a ______item in my home but a representation of life, and the ability to find ______ even in challenging circumstances.

6 . 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.

Every living thing in nature struggles to survive. Most plants are     1     by animals and people, as well as by other plants, and may have to live in difficult conditions. Plants survive by     2     to life in different environments, and by competing     3     with other living things.

Over time, some plants develop features which help them to survive in particular conditions. Plants with helpful features are more     4     to survive and reproduce. Plants without these features often die out. The process is called natural     5    .

8 . 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.”

9 . Now, a study proves that gardens are more than just a pretty place. The study, by researchers at Illinois State University, demonstrates that such constructed gardens can have a measurable and positive impact on water quality.

Floating gardens are essentially platforms built and wrapped in coconut husks (椰子壳), and filled in with native plantings. As plants grow, they extend their roots into the water. On the North Branch of the Chicago River, non-profit Urban Rivers and its partners are developing a mile-long floating eco-park called the Wild Mile. The re-development of this former industrial canal is Urban Rivers’ important project. As part of the park, floating gardens, attached to shore, are being fixed.

The primary aim of the floating gardens is beautification. But the Illinois State team, from the University’s Department of Geology, Geography, and the Environment, saw an ideal setup for a controlled experiment. “We joined it because it’s the perfect opportunity to see if there’s an influence on water quality,” explains lead author Abigail Heath.

The study is novel: previous studies have explored floating gardens’ influence on water quality over time, primarily in wastewater treatment ponds, but not over space, in moving water. The project also matches well with Urban Rivers’ broader goals. “The city is interested in bettering water quality,” says Phil Nicodemus, Urban Rivers’ Director of Research. “Happily, Illinois State took part in it later.”

Could this small human-made park improve water quality? An average of data collected over the course of the study shows middle but definitive improvement. For example, nitrogen (氮) dropped from 4.69 milligrams per liter in surface water to 4.43 milligrams per liter, a drop of about 1 percent.

“Despite how small this garden was, there was measurable improvement in water quality from upstream to downstream,” notes Heath. She and her colleagues see this as a model for how large floating gardens should be to help improve water in similar settings. “Even this tiny garden makes a difference,” she says.

With high yield and superior quality, Chinese hybrid rice varieties have been introduced around the world,     1     (benefit) more people. The export of China’s hybrid rice technology started many years ago. In 1979, China provided hybrid rice seeds to another country for the first time, and 40 years later, in     2     (real), China’s hybrid rice has been planted in dozens of countries in the world.

In the past 40 years, Chinese scientists     3     (devote) to providing assistance to many other countries. China has trained more than 14,000 hybrid rice professionals for more than 80 developing countries through international training courses. This technology has spread     4     more and more places in the world so far.

Yuan Longping,     5     cultivated the world’s first high-yield hybrid rice strain not only earned respect from Chinese people but also the global community. 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.
