From “pocket parks” between communities to forest parks in the outer cities, local governments are     1     (ambition) to make China’s cities greener. That’s     2     there are more parks in cities these days.

From 2021 to 2022, Shanghai transformed 62 woodlands into leisure spaces. These leisure spaces open up forests,     3     allows visitors to enjoy natural beauty as well as wildlife. In urban     4     (area), more companies and universities are sharing their greenery. For instance, the Shanghai Research Institute of Sports Science opened its 1,000-square-meter green space to the public.     5     (join) by historical buildings in the area, the park can provide more space for tourists to rest.

Apart from meeting people’s needs, parks can also do good to the environment. Take Beijing’s Central Green Forest Park     6     an example. Since it was opened in 2020, the park     7     (reach)carbon neutrality (碳中和). It means although the park’s facilities produce carbon dioxide, more can be     8     (take) in by the plants there. The park also fully reuses rainwater and creates green energy     9     (supply) the park. As cities in China become greener, “park cities” are becoming a reality. The concept of a park city was     10     (initial) put forward in 2018. It is a concept that takes the form of an improved natural environment in all aspects, noted China Daily.

3 . 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。

Camellias (山茶花) are available in a great range     1     colors — red, pink, white and mixed colors. For the longest time, the golden camellias lived in a valley     2     was unknown to the outside world.

In the 1960s, Chinese scientists announced their discovery of the golden camellias. It was an     3     (amaze) announcement for the international gardening community. Also, the discovery made     4     achievable to create yellow camellias, though creating a new kind of golden camellia was not very easy.

Unfortunately, in the past, golden camellias were cut down in large numbers because     5     (local) needed the limited land space for farming. In 1986, a nature reserve (自然保护区)     6     (build) in a mountain valley from 200 to 500 meters above sea level, so the camellias could be well protected. Years ago, Huang Zainian and his brothers took up the work. In the past 10 years, the Huang brothers have made a great     7     (contribute) in protecting the camellias. Even in hard times they didn’t cut down any golden camellias.

Year after year, the Huang brothers spent much time working     8     eventually made their hard work pay off. Now the golden camellia is     9     city flower of Fangchenggang. And life for the Huang brothers is greatly improved by     10     (plant) golden camellias.

4 . Most plants you see out in nature are leafy and green, at least for some part of their lives. That’s because they use green pigments, which are called chlorophyll (叶绿素), to harvest energy from sunlight. But the plant Hydnora Africana, doesn’t have leaves or chlorophyll at all.

So, how can it survive? Well, it’s a parasite (寄生), and H Africana attaches itself to other plants’ roots, and begins getting sugars, minerals, and water from its host.

At the same time, the parasite grows a root system, living completely underground, until it’s ready to reproduce. At which point, it grows one of the strangest looking flowers in the world. When the flower’s mature, it breaks the soil from beneath and reaches out in order to be pollinated (授粉).

But just as this plant doesn’t look like the normal flower, it doesn’t smell like one either. It gives out a smell like a rotting (腐烂) animal . The smell attracts insects and flies looking for a delicious meal. But when they get inside the flower and find no tasty treat, they can’t get back out again.

There’s a sort of room inside the flower, and the top of the room closes behind the insects. The walls of the flower are also slippery, making escape even more difficult.

Over the course of about a day, the flower’s male organs mature, and the insects get coated in pollen. And at the end of this transformation, the inside of the plant gets less slippery, and the chamber opens, allowing the insects and flies to escape.

At that point, attracted by a new rotting smell, they might just find another H Africana flower and pollinate it as they fall inside.

1. Why is chlorophyll so important to plants?

A．Chlorophyll gives plants green color.

B．Chlorophyll helps leaves to grow.

C．Chlorophyll can harvest energy from sunlight.

D．Its flowers smell sweet.

3. The insects attracted to pollinate will _____.

A．find tasty treat inside the flower.

B．never get out of the flower again.

C．get little chance to pollinate successfully.

D．escape after being trapped about a day.

4. The passage mainly interprets______.

A．What is a parasite.

B．How a parasite to survive.

C．How H Africana reproduce.

D．Why bad smell is so useful.

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 . Planting the right seeds(种子)at the right time will not take as lots of efforts as we think. And some vegetables do grow themselves well without paying too much attention. Here are 4 vegetables that are perfect for a backyard garden.

Green beans

There is really only one important rule for planting green beans—don’t plant them too early. They won’t survive a frost. They may also stop producing in the middle of the summer, but if you continue to water them, they will continue to produce once the temperatures start to drop in early fall. The most time-intensive part of growing beans is in the harvest. The more frequently you pick up beans, the more beans it will grow.

Brussels sprouts(抱子甘蓝)

This sweet vegetable can be grown in nearly any home garden with rich sunlight. They have a long growing season compared with other vegetables. Their taste improves if they are covered with frost. However, they can only bear a few days of cold weather, so be sure to harvest them as quickly as possible.

Broccoli(西兰花)

Broccoli is a cool-weather plant that grows best in spring and fall. It can be planted in early spring for a summer harvest, or in late summer to be harvested in fall. If grown in winter, to avoid heavy frost, broccoli can also be grown indoors and moved to the garden when temperatures rise. When growing broccoli, be sure to watch out for pests(害虫).

Peas

Peas are a great choice for new gardeners. All you need is a container that is at least 10 inches deep and something for the plants to climb. They prefer low temperatures, and once the heat of summer hits, pea plants will stop producing. If your garden space is limited, you can pull them up in the summer and replace peas with another crop that likes the heat

1. What can you do to harvest more green beans?

A．Plant them early.	B．Gather them in time.
C．Grow them indoors.	D．Avoid watering them in summer.

2. What will happen when Brussels sprouts are covered with frost?

A．It will taste better.	B．It will grow better.
C．It will attract pests.	D．It will go bad immediately.

3. What do broccoli and peas have in common?

A．They can survive frost.	B．They enjoy cool weather.
C．They take up a lot of space.	D．They stop growing in summer.

7 . The earth’s climate is largely controlled by how much of the sun’s light and heat is absorbed and reflected. By absorbing the sun’s heat, trees cool the air.

The interaction of this relationship with an area’s topography (地势), latitude (纬度), and altitude, can create microclimates (微气候), just as trees create microclimates almost any place they are by providing a windbreak (风林) and shade. Think about it: On a hot, sunny day, it’s always cooler beneath a shade tree. A city with more tall trees is cooler in the summer than a similar city with fewer trees, which translates into less energy use and lowers cooling costs. Also, in using less energy, less air pollution is created.

The most important role that rural trees and forests play is taking carbon dioxide out of the atmosphere. The living tissue (组织) of a tree is a storage vault (拱顶) for carbon, which would otherwise contribute to the greenhouse effect and to global climate change. To put it most simply, more trees can decrease the rate of climate change and help us withstand its effects, potentially resulting in less intense storms, fewer infectious diseases, a more stable water supply, and fewer wildfires.

Trees, however, are affected by the effects of climate warming. Areas once too cold to support trees now can, and as forests migrate north, harmful insects that were once held at bay (使不能接近) by winter freezes can do damage to native species. Tropical (热带的) vines called lianas (藤本植物) are now growing faster than the trees they climb, causing trees in the Amazon and other rainforests to die at an alarming rate.

Trees and forests can either be the key to slowing climate change and reducing its effects, or they can become its victims. It’s up to us.

1. Trees are believed to create microclimates in that __________.

A．tress can take in large sum of sunlight

B．tress can effectively change the weather

C．tress can help us save more money on cooling

D．tress can stop the strong wind and supply shade

2. With the climate becoming warmer, __________.

A．more types of trees will be endangered

B．some rare forest species will grow faster

C．tropical vines find their wonderful world

D．some harmful insects will be under control

3. What does the underlined word “withstand” mean in the text?

A．Make up.	B．Stand up to.
C．Think about.	D．Bring out.

4. What’s the main idea of the passage?

A．Greenhouse effect is increasing sharply.

B．Climate change does great damage to trees.

C．Many native species will be frozen to death.

D．Forests and climate change influence each other.

8 . 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。

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.

9 . Though they have a small figure, plants are armed with a metabolic (新陈代谢) system that allows them to collect, store and spend hard-earned energy for their survival. Perhaps the best-known part in this plant metabolic network is their ability to turn light into sugars and other forms of energy through photosynthesis (光合作用), a unique ability that allows plants to live in different environments.

But a plant’s dependence on sunlight has always presented one key question: What happens to a plant’s energy supply when night falls and sunlight becomes no longer available? A study published on Monday in the journal Proceedings of the National Academy of Sciences answered the question. Researchers report that a key factor to a plant’s ability to keep energy and survive the darkness of each nightfall rests in what experts call the circadian clock (生物钟).

Circadian clocks are basically chemical timekeepers each plant owns that allow them to work out the passage of time and the duration of their chemical reactions, and give them a rough idea of their daily routine every 24 hours. Experts say like most clocks, these inner timepieces for plants also come with an alarm of sorts. Through a network of genes and cells, researchers say that plants have an inborn ability to adjust (调整) their clocks each night for the benefit of their own survival. Through this network they can know the rising and falling of the sun, how long each night will last and how much energy they need to keep to make it to each morning. This alarm, according to researchers, can single-handedly tell plants how to adjust their nightly metabolic schedule—and give their energy supply suitably—every night with shocking correctness.

The study shows that experts came to this conclusion after experimenting with genes inside Arabidopsis, a small flowing plant related to cabbage. In these plants, researchers discovered a collection of genes largely controlled by a special thing known as superoxide (过氧化物), which is often linked to a plant’s metabolism.
