五、阅读理解（2024年广东省中山市中考英语一模试卷）
Sea grasses meadow（草地） are plants that grow in waters near coasts. They help clean the ocean's water and also provide food for animals like fish. However, sometimes they are in danger. The climate change and human pollution are threatening sea grass meadow in many places around the world.
But the huge sea grass meadow in Shark Bay, off the coast of Western Australia, seems to be growing very well. Scientists from The University of Western Australia and Flinders University wanted to study the sea grass, so they took samples(样本) from 10 different parts of this huge meadow. By comparing the DNA from their samples, the scientists hoped to get an idea of how many different sea grass plants there were in the meadow.
What they learned surprised them—all of the grass samples had almost exactly the same DNA. It meant that they were all just one plant. One big sea grass plant spread out over 200 square kilometers.
So how has the Shark Bay sea grass grown so large Instead of spreading with flowers and seeds(种子)，it spreads by cloning (克隆) itself. As its roots(根) spread out under the sea floor, new plants shoot up from those roots. The Shark Bay sea grass generally grows and spreads about 35 centimeters a year. From this speed, the scientists believe that the plant is about 4, 500 years old.
( )1. What does the underlined word "threatening" in the first paragraph mean
A. Giving help to. B. Bringing danger to. C. Planting more. D. Improving.
( )2. What did the scientists want to know about the meadow from the samples
A. The area it covers. B. The reason why it has grown so little.
C. The water pollution it faces. D. The number of the sea grass types of it.
( )3. Where do new plants for the sea grass grow
A. From its roots. B. From its seeds. C. From its flowers. D. From another plant.
( )4 How do the scientists know about the age of the sea grass
By cloning it. B. By studying its DNA.
C. By knowing its growth speed. D. By testing the water temperature.
( )5. What is the passage mainly about
A. A story. B. A discovery. C. A new law. D. A rule.
