Passage1

Clever trees

There’s nothing better than a walk in the countryside for lifting our spirits.

Connecting with nature has been proven to help our mental health. For some, the

best tonic is to stroll through a forest, but as we admire the trees that surround us, it’s

worth knowing these trees are doing more than just being nice things to look at.

We’re already aware of the healing properties of trees – they produce oxygen and

clean the air we breathe by absorbing about a quarter of all human-caused carbon

dioxide emissions. Deforestation isn’t helping with this which is why so many people

want to save them. But there’s more to these impressive forms of vegetation than we

might think. Researchers have discovered evidence that proves they are actually

intelligent.

It’s thought that trees talk and share resources right under our feet, using a fungal

network. Under the ground are tree roots, and mingling among them, along

with bacteria, are thousands of superfine threads of fungi, known as hyphae(菌丝)

. And research has shown that they are all interconnected. They can help each other by

sharing nutrients, and they can even warn of approaching threats. Scientists say it’s

like the trees are talking to one another.

Ecologist Suzanne Simard has called this network the Wood Wide Web. She

discovered that parent trees use this network to help their offspring. Speaking to the

BBC, she said: “We found that the parent trees would favour those seedlings that were

of their own kin versus the strangers” by sending them more nutrients. She also found

that trees are smart enough to change their behaviour and have managed to adapt and

survive in a changing environment.

So it seems trees really are the stars of our natural world, and with around three

trillion of them on our planet, it’s time to show them some respect if we want them

to flourish.

1. How do trees help improve the air quality?

A. By helping to share nutrients

B. By absorbing all carbon dioxide emissions that human cause.

C. By sending out oxygen

D. By absorbing about a quarter of all human-caused carbon dioxide emissions.

2. What does the last sentence“So it seems trees really are the stars of our natural

world, and with around three trillion of them on our planet, it’s time to show them

some respect if we want them to flourish.” mean ?

A. It is high time that we should love trees and take measures to protect trees.

B. It tells us trees are really important in our life.

C. Trees are the stars of natural world.

D. We should get close to nature.

3.The word “offspring”means______.

A. 祖先 B. 后代 C. 亲戚 D.家人

Passage2

Remote tech a key driver for education

Remote technologies will play an increasingly-critical role in driving the

education industry, as the COVID-19 pandemic forced the world to go remote,

according to an industry insider.

"Remote technology is continuing to empower online education, with large migrations

online. With the continuous application of new technology methods such as big data

and artificial intelligence, students' learning outcomes have been significantly

improved," said Wang Yan, chief architecture officer at Zuoyebang.

Wang made the remarks after "remote everything" was nominated by MIT

Technology Review for its 10 Breakthrough Technologies list for 2021 that features

10 advances predicted to have a big impact on our lives.

"Technology and outcomes are two major challenges that companies face when

they transform from offline to online. The education industry is facing the largest

traffic challenge ever," Wang said.

To upgrade the infrastructure, Zuoyebang has continued to upgrade its technology,

changing from its original single cloud service to multiple cloud services and from
