5、[衡水金卷]广东省2025届高二年级4月份联考数学试题

Florida has some of the best beaches in the world. Thousands of people visit the state to enjoy the sun and the sand. But these beaches are also home to sea turtles. Female sea turtles come from the ocean and onto these beaches at night. They dig a hole, lay many eggs, and cover their eggs with sand. They use their fins (脚蹼) to crawl back across the beach and return to the ocean. However, the creatures have a hard time on beaches now.
Local volunteers and researchers in Florida take direct action to help the turtles. They look closely at the large area of sand to locate where the sea turtles laid their eggs. When they’ve figured out where the eggs were laid, they mark the beach off so that no one can enter the area and disturb the eggs. They also collect information about the nests and tracks to help scientists study sea turtles.
Another problem for sea turtles is the quick urbanization (城市化) near beaches. Bright lights on buildings near the beach can negatively impact sea turtles. Baby sea turtles usually hatch (出壳) on the sandy beach and head to the ocean. When there is bright light coming from the other side of the shore far from the ocean, the baby turtles get confused. They do not know which way to go. Many of them do not make it to the ocean and die. Now, residents who live close to a beach try to turn off their lights at night as early as possible.
Many people believe the best way to save these creatures is through organizations like the Marine Conservancy. The Marine Conservancy helps people take steps that will help reduce the threats that put sea turtles in danger. Sometimes, turtles mistake plastic bags for jellyfish (水母). They eat this trash and die. Florida residents (居民) can volunteer for beach clean-ups and make sure to pick up their own litter. However, sea turtles are still starving because of overfishing and climate change. In 2025, the organization aims to help the creatures find a new source of food by planting seagrass underwater.

A. By increasing the size of beaches.
B. By tracking sea turtles’ movements.
