Scientists have recently discovered the world’s largest known field of sea grass. They did it using videos shot by some extraordinary helpers. The work should help protect the sea grass, and also shows off a powerful way to explore the ocean.

As a shelter for many sea creatures, sea grasses are flowering plants that normally grow in shallow waters near coasts. They grow in thick fields, known as seagrass meadows (海草床), which help clean the ocean water. More importantly, they are called “ocean lung”. They help in the fight against the climate crisis. That’s because they store huge amounts of carbon — the major source of global warming.

Considering the urgent need to protect seagrass meadows and the challenges to spot them, scientists decided to have tiger sharks help the research.

Tiger sharks are inborn fast swimmers, and spend a lot of time in seagrass meadows. Between 2016 and 2020, the researchers attached cameras and other trackers to the fins of seven tiger sharks, and then let them go again. The cameras were designed to fall off after hours and float to the surface. Tracking signals helped find the floating cameras and collect the videos the sharks had taken while traveling for miles. Moreover, other tools were used, including satellite images, as well as images taken by divers and boats.

Putting all this information together, the scientists learned that the waters around the Bahamas are home to the largest seagrass meadow ever discovered. Different from previous studies, the program discovers how useful large underwater animals can be in helping to learn more about life under the sea. Oliver Shipley, a scientist from the team, says animals like tiger sharks are going to take us to new places that we didn’t know existed.

1. Why do seagrass meadows urgently need protection?
A.Damaging them will worsen climate crisis.
B.They determine the cleanliness of ocean water.
C.Sea creatures can’t survive without their shelter.
D.Their existence balances the underwater ecosystem.
2. How did tiger sharks help the scientific research?
A.By tracking signals scientists sent.
B.By bringing back cameras with videos.
C.By carrying the recording equipment around.
D.By spending a lot of time in seagrass meadows.
3. What is the highlight about the research according to the text?
A.Leading scientists.B.Unusual research assistants.
C.Multiple experimental tools.D.Advanced theories.
4. Which is the most suitable title for the text?
A.The Cooperation between Man and Animals
B.The key to protecting the Sea—Tiger Sharks
C.Sea Grass: An Undervalued Plant
D.Ocean Lung Monitored in a New Way

Create a small garden

Plants and flowers are part of nature as well and even the tiniest amount of space can be turned into a beautiful garden. If you’ve got a balcony (阳台), fill it with pots full of flowers.    4    . Imagine how satisfying it would be to share them with your friends and family.

文章大意:这是一篇说明文。主要介绍了现在,似乎越来越多的动物出现在我们意想不到的城市里。但科学家们已经了解到,一些物种在城市里生活得更好。

【推荐2】Now it seems that more and more animals are showing up in cities where we would not expect them to. But scientists have learned that some species do better in cities. Take peregrine falcons (游隼) for example. They use tall city buildings to make homes, man-made lighting to hunt at night, and warm air currents created when the sun beats down on city surfaces to fly with less effort.

Some animals adapt well to city life, and some do not. For example, squirrels (松鼠) do amazingly well living in cities, while wolves have never seemed to get the hang of it. Usually, animals that eat a lot of different things, called generalists, do much better in cities than specialists, which eat one specific kind of food. Smaller animals are also more likely to live in cities than bigger animals. Some people believe animals that do well in cities might be smarter than the ones that do not, but more research is needed on this.

Many animals have even learned cool tricks to live in cities, and these behaviors help them find more food or mates (伴侣), or avoid people. To learn about these behaviors, we use recording devices to spot animals, microphones to record their sounds, and tracking equipment to follow them. Scientists use many different tools to study what animals eat, how healthy they are, how they compete with each other, and more.

Humans are turning the planet into cities and farms, which does not leave many other places for most wildlife to live in. So, what can we do? At home, we can cover our garbage carefully because it is not good for wild animals. We can also plant some native plants that wildlife might like. Seeing animals in a city, we can give them space and watch them from far away. We could also try some creative things like green roofs where birds and insects can live in.

To do that, we need to know what kind of habitats different species need, and how to prevent human-wildlife conflicts. We still have a lot to learn.

1. How does the author develop paragraph 1?
A.By providing statistical data.B.By making a comparison.
C.By giving an example.D.By stating arguments.
2. What kind of animals survive better in cities according to the author?
A.Those with close mates.B.Those with long diet lists.
C.Those with fast movement.D.Those with high intelligence.
3. What does the author suggest we do in paragraph 4?
A.Restrict urban and agricultural development.
B.Make our cities wildlife-friendly.
C.Plant new varieties of plants.
D.Sort our garbage carefully.
4. Where can the text be found?
A.In a short story.B.In a health journal.
C.In a business report.D.In a science magazine.

文章大意:本文是说明文。文章主要讲述植树造林的相关情况。

【推荐3】Around the world there is an increase in the demand for reforestation. This is because the consumption of the forests has affected not only the animals living in the area but also the people. And reforestation is about the rebuilding of the forests that have been severely destroyed. It can offer a lot of benefits when the recreation is successful.

    1    This includes collecting seedlings (幼苗) that are native in the area to make sure that there is a natural reconstruction of the area. Some additional trees which are not native in the area also need to be planted.     2    The importance of having multiple species of trees is considered to make sure that the needs of other species that will live and grow in the area are met.

Destroying a forest is easy but rebuilding it is really hard.     3    The plan must include accurate spacing on plants and trees. This is to ensure that they won’t cover each other while they grow.     4    

The forest greatly helps in the reduction of the air pollution. Trees are responsible for the production of oxygen and absorption of carbon dioxide.    5    It is there for a reason just like everyone else on this planet.

There cannot be a better way to restore the balance of nature than to increase the forest area. We must remember that the forest is a natural habitat of wide variety of animals and plants. In this manner, there is no substitute for reforestation.

A.And global warming will speed up the destruction of forests.
B.Keep in mind that you can’t just plant the seedlings anywhere.
C.Recreations won’t work until all these details have been considered.
D.So a good plan is needed to make the reforestation a successful one.
E.The forest also protects us from typhoons and other natural disasters.
F.There are many things to be done when it comes to this type of effort.
G.It is important to make sure that they are suited to the climate and the type of soil.
