Ⅰ.阅读理解
A
　　Scientists have discovered the world’s largest known field of sea
grass.They did it using videos shot by some unusual helpers： tiger
sharks.The work should help protect the sea grass， and also shows off a
powerful way to explore the ocean.
　　Sea grasses are flowering plants that normally grow in shallow waters
near coasts.They grow in thick fields， known as meadows（草地）.Sea
grass meadows help clean the ocean’s water， and provide food and
shelter for many sea creatures.Importantly， sea grass meadows also help
in the fight against the climate crisis.That’s because they store huge
amounts of carbon — the harmful pollution that’s making global
warming worse.
　　But though they’re very important， scientists don’t have a good
idea of the size and number of the world’s sea grass meadows.The
meadows can be hard to spot and the ocean is so huge that it’s simply not
possible to study it all by diving.
　　So a team of scientists decided to have sharks help with the
research.Tiger sharks are huge， strong， and deadly.But they also live
underwater， are fast swimmers， and spend a lot of time in sea grass
meadows.
　　Between 2016 and 2020， a team of researchers attached cameras and
other trackers to the fins of seven tiger sharks.After catching the sharks，
the scientists worked quickly to attach the equipment， then let them go
again.
　　The cameras were designed to fall off after a few hours and float to
the surface.Tracking signals helped the scientists find the floating cameras
and collect the videos the sharks had taken.The scientists were left with
hours of videos taken as the sharks traveled for miles over the sea floor.
　　Putting all this information together， the scientists learned that the
meadow covers at least 25，500 square miles （66，000 square
kilometers）， and could be as large as 35，500 square miles （92，000
square kilometers）.The discovery means that the world has roughly 40%
more sea grass meadows than scientists previously thought.However，
much still remains to be done to protect them.

Margaret Southern was a special-needs teacher from Greenville，
South Carolina， who died in 2012 at age 94.Southern loved children and
animals.Before she allowed Mike Shain， vice president of wealth
management at UBS， to handle her investments， she made him promise
to take in her dog， Molly， if anything happened to her.“I know
you’ll take care of her，” she told him.
In fact， Southern outlived Molly by several years and had her buried
in her yard.But she continued to worry about animals， especially those
that were homeless.When she died， she left half her $8.4 million estate
（财产） to the Greenville Humane Society — even though she’d never
had any direct contact with the organisation — and the other half to the
Community Foundation of Greenville， which distributed the money to
organisations that benefit early childhood education and special education
for children.She also left money to various friends and families.
“It’s a wonderful surprise to wake up and find a very modest
woman who cares greatly for our community and its children，” said
Susan Shi， PhD， founder of the Institute for Child Success.
Southern’s wealth also came as a shock to most who knew her.She
lived in a modest town house and got around Greenville in a common
car.Her money came from a few shares of stock left to her by her
husband， who had died in 1983.She added to that through the 80’s.
“What’s exceptional is she didn’t spend it on herself， and she
was able to accumulate a lot of money that she wanted to direct to her
dearest charities，” Bob Morris， president of the Community
Foundation， told the Greenville News.“I haven’t met a lot of people
like that.”
Did their generous natures help Southern and these other
extraordinary givers live so long？ It’s possible.Studies have found that
people who are charitable， whether it’s via volunteering or donating
money， tend to have lower blood pressure， less stress， and longer
lives.

you think.Think， and then act.We need to take action on our dependence
on plastic.We’ve been producing plastic in huge quantities.Drinking
bottles， shopping bags and even clothes are made with plastic.9
（　　） What happens to all the rest？This is the question the film A
Plastic Ocean answers.
The film begins as a journey to film the largest animal on the planet，
the blue whale.But during the journey the filmmakers make the shocking
discovery of a huge， thick layer of plastic floating in the Indian
Ocean.10（　　） In total， they visited 20 locations around the world
during the four years to make the film.
In the film， there are beautiful shots of the seas and marine life.11
（　　） We see how marine species are being killed by all the plastic we
are dumping in the ocean.The message about our use of plastic is painfully
obvious.
12（　　） In the second half， the filmmakers look at what we can
do to deal with the problem.
They present short-term and long-term solutions.These include
avoiding plastic containers and recycle as much as you can.The
filmmakers also stress the need for governments to work more on recycling
programmes.
We make a shocking amount of plastic.Over 300 million tons of
plastic are produced every year， and at least 8 million of those are
dumped into the oceans.The results are disastrous， but it isn’t too late
to change.13（　　）
A. This causes them to travel around the world to look at other affected
areas.
B. Once you’ve seen the film， you’ll realise it is time to do our part.
C. It has raised public concern all over the world.
D. We live in a world full of plastic， and only a small amount is
recycled.
E. But the film doesn’t only present the negative side.
F. In conclusion， we only have one Earth to live on.
G. These are contrasted with dumps of plastic rubbish.

使他们去到更多被影响的地方。故A项（这使得他们到世界各地去观
察其他受影响的地区）符合语境，A项中的This指代上文提到的the
shocking discovery of a huge， thick layer of plastic floating in the Indian
Ocean。
11. G　根据上下文语境可知，前后内容“美好的景色”与“倒进海
里的垃圾”形成对比。故G项（这些与倾倒的塑料垃圾形成对比）符
合语境，G项中的These指代上文提到的美丽镜头。
12. E　上一段提到这部电影展现出了大量的垃圾倒进海里的消极一
面，结合下文 In the second half， the filmmakers look at what we can do
to deal with the problem.可知，这部电影不仅仅是展示了消极的方面，
还展示了如何解决问题。故E项（但是这部电影不只呈现了消极的一
面）符合语境。
13. B　根据上文We make a shocking amount of plastic.和The results
are disastrous， but it isn’t too late to change.可知，我们制造了太多
的塑料垃圾，结果将会是灾难性的，但现在改变还不算太晚。故B项

Ⅰ.阅读理解
A
　　Scientists have discovered the world’s largest known field of sea grass.They did it using videos shot by some unusual helpers： tiger sharks.The work should help protect the sea grass， and also shows off a powerful way to explore the ocean.
　　Sea grasses are flowering plants that normally grow in shallow waters near coasts.They grow in thick fields， known as meadows（草地）.Sea grass meadows help clean the ocean’s water， and provide food and shelter for many sea creatures.Importantly， sea grass meadows also help in the fight against the climate crisis.That’s because they store huge amounts of carbon — the harmful pollution that’s making global warming worse.
　　But though they’re very important， scientists don’t have a good idea of the size and number of the world’s sea grass meadows.The meadows can be hard to spot and the ocean is so huge that it’s simply not possible to study it all by diving.
　　So a team of scientists decided to have sharks help with the research.Tiger sharks are huge， strong， and deadly.But they also live underwater， are fast swimmers， and spend a lot of time in sea grass meadows.
　　Between 2016 and 2020， a team of researchers attached cameras and other trackers to the fins of seven tiger sharks.After catching the sharks， the scientists worked quickly to attach the equipment， then let them go again.
　　The cameras were designed to fall off after a few hours and float to the surface.Tracking signals helped the scientists find the floating cameras and collect the videos the sharks had taken.The scientists were left with hours of videos taken as the sharks traveled for miles over the sea floor.
　　Putting all this information together， the scientists learned that the meadow covers at least 25，500 square miles （66，000 square kilometers）， and could be as large as 35，500 square miles （92，000 square kilometers）.The discovery means that the world has roughly 40% more sea grass meadows than scientists previously thought.However， much still remains to be done to protect them.
1.What’s the second paragraph mainly about？（　　）
A.How sea grass meadows grow.
B.Where sea grass meadows grow.
C.The benefits of sea grass meadows.
D.The problems of sea grass meadows.
2.When were the tiger sharks let go by the scientists？（　　）
A.After collecting the videos.
B.Before shooting the videos.
C.After finding the cameras.
D.Before attaching the trackers.
3.What does the discovery mean to the scientists according to the last paragraph？（　　）
A.A wake-up call.　　 B.An unexpected blow.
C.A promising future. D.A pleasant surprise.
4.What would be the most suitable title for the text？（　　）
A.Sea Grass Meadows Are Fighting Global Warming
B.Sea Grass Meadows Do Good to Oceans and Sharks
C.Sharks Help Discover World’s Largest Sea Grass Meadow
D.Scientists Try to Research Sharks and Sea Grass Meadows

Margaret Southern was a special-needs teacher from Greenville， South Carolina， who died in 2012 at age 94.Southern loved children and animals.Before she allowed Mike Shain， vice president of wealth management at UBS， to handle her investments， she made him promise to take in her dog， Molly， if anything happened to her.“I know you’ll take care of her，” she told him.
In fact， Southern outlived Molly by several years and had her buried in her yard.But she continued to worry about animals， especially those that were homeless.When she died， she left half her $8.4 million estate （财产） to the Greenville Humane Society — even though she’d never had any direct contact with the organisation — and the other half to the Community Foundation of Greenville， which distributed the money to organisations that benefit early childhood education and special education for children.She also left money to various friends and families.
“It’s a wonderful surprise to wake up and find a very modest woman who cares greatly for our community and its children，” said Susan Shi， PhD， founder of the Institute for Child Success.
Southern’s wealth also came as a shock to most who knew her.She lived in a modest town house and got around Greenville in a common car.Her money came from a few shares of stock left to her by her husband， who had died in 1983.She added to that through the 80’s.
“What’s exceptional is she didn’t spend it on herself， and she was able to accumulate a lot of money that she wanted to direct to her dearest charities，” Bob Morris， president of the Community Foundation， told the Greenville News.“I haven’t met a lot of people like that.”
Did their generous natures help Southern and these other extraordinary givers live so long？ It’s possible.Studies have found that people who are charitable， whether it’s via volunteering or donating money， tend to have lower blood pressure， less stress， and longer lives.
5.What did Margaret Southern want Mike Shain to do？（　　）
A.Take care of her. B.Do her housework.
C.Look after her dog. D.Manage her estate.
6.What does the Greenville Humane Society probably do？（　　）
A.It helps children. B.It protects animals.
C.It helps disabled people. D.It protects the environment.
7.What’s the author’s purpose of using Bob Morris’s words？ （　　）
A.To provide some more proof.
B.To give some extra information.
C.To explain Margaret Southern’s act.
D.To speak highly of Margaret Southern.
8.What’s the main idea of the last paragraph？（　　）
A.Why people donate money.
B.Why people work voluntarily.
C.Giving makes one live long.
D.The benefits of doing good.
