For over 100 million years, they have swum through Earth’s oceans. These ancient reptiles can grow up to 1.5 meters long and live for 80 years or more.​ Every year, female sea turtles return to the same beaches where they were born to lay eggs. They dig holes in the sand and lay around 100 eggs at a time. After two months, baby turtles break out of their shells and rush to the ocean. But this journey is dangerous—many are eaten by birds or get lost because of bright lights from nearby buildings.​ Sadly, sea turtles face more problems today. Plastic pollution is a big threat. Turtles often mistake plastic bags for jellyfish, their favorite food, and eating plastic can kill them. Also, fishing nets sometimes catch turtles by accident.​ Luckily, people are working to save them. In some countries, volunteers patrol beaches at night to protect nesting turtles. They also turn off beach lights to help baby turtles find the ocean. Many places have banned plastic bags, and fishermen use special nets that let turtles escape.​ Scientists say that if we keep helping, sea turtles will continue their long journeys for many more years. These gentle creatures remind us that we must care for our oceans.​ 根据短文内容，选择最佳答案。​ 16．How long can sea turtles live?​ A．Up to 50 years.​ B．Up to 80 years.​ C．Up to 100 years.​ D．Up to 150 years.​ 17．Why do baby turtles get lost?​ A．They are afraid of birds.​ B．The sand is too hot.​ C．Bright lights confuse them.​ D．They can’t swim well.​ 18．What do sea turtles often mistake for jellyfish?​ A．Fishing nets.​ B．Plastic bags.​ C．Beach lights.​ D．Sand holes.​ 19．What do volunteers do to help sea turtles?​ A．They clean the beaches every day.​ B．They carry baby turtles to the ocean.​ C．They turn off lights to guide baby turtles.​ D．They teach fishermen to catch more turtles.​ 20．What is the main idea of the passage?​ A．Sea turtles are ancient reptiles.​ B．Sea turtles face many dangers.​ C．People are working to save sea turtles.​ D．Sea turtles need our help to survive.​ 四、选词填空 阅读短文，从方框中选择适当的词并用其正确形式填空，使短文通顺、意思完整，每词限用一次。 probable   hunt   in   live   lucky   human   get   protect   fact   ourselves Wild animals are our friends.
