The mangrove wetlands (红树林湿地) of Shenzhen’s Futian and Hong Kong’s Mai Po are very valuable. Every year, many waterbirds fly from East Asia to Australia. These wetlands are a key place for them to rest. These years, Shenzhen and Hong Kong have worked together to protect these important wetlands.
Why are these mangrove wetlands so important Because they are like nature’s protectors. They make a natural wall, protecting coasts from big storms (暴风雨). Besides, the thick forest of mangrove trees provides a perfect home for birds. They build nests there and look after their babies. “Even during storms, baby birds are safe in the mangroves,” said Simon Wong from Hong Kong’s nature team. What’s more, mangroves help take in CO and clean the water. As a result, they are helpful for both nature and humans.
To protect the wetlands together, Shenzhen and Hong Kong have used different ways since 2023. One of them is to protect birds’ homes with the help of modern AI technology. Thanks to their efforts, the population of endangered birds in the wetlands has grown. For example, there were only about 300 black-faced spoonbills (黑脸琵鹭) around 30 years ago. Now there are nearly 7,000.
In November 2024, the two cities started a new part of their teamwork. The International Mangrove Center (IMC) in Shenzhen opened. The IMC does research on mangrove protection, shares useful ideas and gives classes to the public. Its opening helps Shenzhen and Hong Kong work better to protect the wetlands. It also shows the world how cities can join hands to protect the environment.
36．What does the underlined word “them” in paragraph 1 mean
A．Cities. B．Wetlands. C．Waterbirds. D．Mangroves.
37．What can we learn from paragraph 2
A．Mangroves are unsafe for baby birds.
B．Mangroves can protect tall buildings from storms.
C．Mangroves can produce a lot of CO and dirty water.
D．Mangroves are good for not only nature but also people.
38．Why does the writer talk about black-faced spoonbills’ population
A．To introduce modern AI technology.
B．To tell readers what the birds look like.
C．To explain why endangered birds are important.
D．To show the success of protecting birds’ homes.
39．What can we infer (推断) from the last paragraph
A．Students can do research on mangrove protection in the IMC．
B．The IMC guides cities to work better together and protect nature.
C．The IMC mainly helps the two cities to build more mangrove forests.
D．People don’t need to worry about wetland problems because of the IMC．
40．What is the main idea of the passage
A．Mangroves provide safe homes for waterbirds.
B．The IMC in Shenzhen helps protect the wetlands.
C．There are more black-faced spoonbills in Shenzhen.
D．The two cities protect the mangrove wetlands together.
