1 . In many people’s eyes, plants are quiet and passive. They can’t talk. They can’t walk.     1    .

Or can they? A new BBC documentary series, The Green Planet, gives us a new look at plants. Released on January 10 on Bilibili, it uncovers the wonderful and dramatic ways that plants behave.

Plants compete against each other to live. Each species has its own ways of defense. In rainforests, different kinds of plants race for sunlight. The forest floor is described as a “battlefield” in the series as only two percent of the sunlight filters (透过) through it.     2    . But they are caught up in a vine (藤蔓) that tries to take a ride. Finally, they are both overtaken by a fast-growing balsa tree. As the balsa’s leaves are smooth, the vine can’t get a hold. Similarly, some trees make poisonous sap (毒汁) to protect themselves.

    3    . In deserts, the roots of Euphrates poplar are connected. If a tree finds water, it will share it with others through the roots. Studies also show that plants use fungus (真菌) in the soil as a way to “talk” to each other. It’s kind of like how Wi-Fi works.     4    .

The series not only lets us wonder at the plant world but pushes us to understand that plants are important. “    5    . We depend upon them for every mouth of food that we eat and every breath that we breathe,” said David Attenborough, presenter of the series. It’s time to look after wild plants just as carefully as our houseplants.

A．And they can’t think like us

B．Plants are the basis of all life, including ourselves

C．The Green Planet reveals the secret lives of plants

D．Plants also help each other and even communicate

E．Some plants like Monstera spread their big leaves to reach light

F．Filming took three years to complete and took place in 27 countries

G．If a tomato plant gets a leaf disease, it can tell nearby plants about it

2 . Many animals move from one place to another at certain times of the year. This _______ movement is called migration (迁徙). They migrate to _______ food, or in search of warmer weather. One of the most wonderful migrations in nature is that of the North American monarch butterfly.

Every _______, millions of these beautiful insects with fine black and orange wings begin a long and _______ journey. Somehow they manage to _______ around 4,000 kilometres _______ and find their way to California or Mexico. _______, until recently no one knew how they did this. A team of scientists led by Professor Eli Shlizerman at the University of Washington has now found the _______. They have found out that the monarch is able to _______ the time of day. It uses its eyes to measure the ________ of the sun. These two pieces of information allow the ________ to determine the way to go. ________, it manages to reach where it will spend the winter.

The solution to the mystery of the monarch’s amazing ability comes at a time when it is in serious trouble. Its ________ has crashed by as much as 90 per cent in the last few years. ________, human activity is the main reason why the number of monarch butterflies is falling. The research on the monarch’s ________ has however led to a greater awareness of this creature.

5 . Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.

Although there are many different types of food, some animals spend their lives eating only one type. The giant panda eats only one particular type of bamboo. Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet. The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.

Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food,therefore, has become an area of study in modern life.

1. Which of the following eats only one type of food?

A．white butterfly	B．small bird.
C．The bear.	D．The fox.

2. Certain animals change their choice of food when _______.

A．the season changes

B．the food color changes

C．they move to different places

D．they are attracted by different smells

3. We can learn from the last paragraph that _______.

A．food is chosen for a good reason

B．French and British food is good

C．some people have few choices of food

D．some people care little about healthy diet

4. What will most probably be talked about in the next paragraph?

A．Why choosing the right food is important.

B．How to choose the right food.

C．The right amount of food for a person.

D．Vegetables matter more than meat and sugar.

6 . Contrary to the long-held belief that plants in the natural world are always in competition, new research has found that in severe environments adult plants help smaller ones and grow well as a result.

The research, led by Dr Rocio, studied adult and seedling (幼苗) plants in the ecological desert in the south-east of Spain.

Dr Rocio said, “If you’re a seedling in a poor land — the top of a mountain or a sand hill, for example—and you’re lucky enough to end up underneath a big plant, your chances of survival are certainly better than if you landed somewhere on your own. What we have found, which was surprising, is an established large plant, called a ‘nurse’, protects a seedling; it also produces more flowers than the same plants of similar large size growing on their own.”

Other benefits of nurse-seedling partnerships include that more variety of plants growing together can have a positive effect on the environment. For example, vegetation areas with nurse plants with more flowers might be able to attract higher numbers of pollinators (传粉者) in an area, in turn supporting insect and soil life and even provide a greater range of different fruit types for birds and other animals.

“The biggest winner for this system of nursing a plant is biodiversity (生物多样性),” Dr Rocio said. “The more biodiversity an area, the greater number of species of plants, insect life, mammals and birds, and the better the chances of long-term healthy functioning of the environment and ecosystems.” This system is win-win for adult and seedling plants in unfavorable environments.

The research is of value to those who manage and protect plants in tough environments. Most home gardeners and farmers plan to ensure their soil and conditions are the best they can be for plant growth, but the findings might be of value to those who garden in bare places.

1. What is a common understanding of plants?

A．They can help each other.	B．They can survive ill conditions.
C．They compete with each other.	D．They grow well on their own.

2. What will happen to seedling plants if they grow under adult plants?

A．They will produce more flowers.	B．They will die owing to competition.
C．They will make adult plants larger.	D．They will benefit from adult plants.

3. Who will benefit from the new research?

A．People studying organic farming.

B．People protecting plants on sand hills.

C．People wanting to change biodiversity.

D．People keeping more animals on the farm.

7 . Paws walk across my keyboard, and my cat Monty lies on my lap, unaware of the world beyond our garden fence. In these uncertain times of the pandemic, the company of animals is needed more than ever. To the joy of our cats, dogs and all pets in between, staying at home is an opportunity to give them our undivided attention. In return, they provide us with a much-needed source of happiness.

Pet ownership is well known to help settle anxiety, reduce loneliness and lift moods. Even as we spend an unprecedented（空前的）amount of time in isolation（隔离）, pets are still acting as channels to building a sense of community as people share pictures of their beloved companions online in an effort to raise spirits.

It is in such times that we realize just how much our pets matter as part of the family. As a long-term cat lady, I have never questioned that a pet is a precious member of the household. Our pets can be as valuable as our human family members in teaching us about ourselves and how to approach the world. In short, our animals' love and loyalty are unique.

As such, the death of a pet can feel as sad as that of a close friend or family member. The grief（悲痛）remains something that is often seen as shameful, and many admit to demanding time off work without being honest about why. However, with the loss of a pet comes an emptiness where their unconditional love once was, and moments in the day once dedicated to their care become suddenly unoccupied.

Vet and author James Herriot wrote, "If having a soul means being able to feel love, loyalty and thankfulness, animals are better off than a lot of humans." Pets are an additional member of the family, and now more than ever, they can serve as models for the kind of basic humanity we ought to be extending to an unstable world.

1. What is the main idea of paragraphs 1 and 2?

A．How to play with pets.	B．How keeping a pet benefits humans.
C．How the author started to keep a pet.	D．How pets keep people away during isolation.

2. What does the author think pets mean to humans?

A．They are as precious as our family members.	B．They are only secondary to family members.
C．They are more like teachers than friends.	D．They help us take care of our family.

3. Why do people lie when requesting time off after the death of a pet?

A．They feel puzzled about its death.

B．They consider it a private family thing.

C．They are annoyed by the feeling of emptiness.

D．They feel embarrassed about their sadness over it.

4. What does James Herriot imply in the last paragraph?

A．Pets can teach us to be better humans.	B．Pets need more attention now than ever.
C．Pets and humans have little in common.	D．Pets can act as a tool to calm the world.
