Sea Turtles' Long Journey
Sea turtles are amazing travelers. 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.

阅读配对：The Amazing Beavers
以下是关于河狸的五个段落，请从 A-F 中为每个段落选择最合适的标题（其中一项为多余选项）。
段落
1._________Beavers are great builders. They use branches, stones, and mud to build dams across rivers. These
dams create ponds, which become their homes. A beaver can cut down a small tree in just 15 minutes with its sharp
teeth!
2._________The ponds made by beavers are useful for many animals. Fish lay eggs in the calm water, birds find
food near the ponds, and frogs live in the wet grass around them. Even after beavers leave, the ponds stay and help
plants grow.
3._________Once, beavers lived in many parts of North America and Europe. But in the 1800s, people hunted
them for their thick fur and the scent glands used in medicine. This made their numbers drop sharply.
4._________Today, people are working to bring beavers back. In some countries, laws stop hunting. Workers also
build special fences to protect trees, so beavers and humans can live together without problems.
5._________In 2021, a group of scientists studied beavers in Scotland. They found that beaver dams helped stop
floods—water stayed in the ponds instead of rushing down hills. This surprised many people who once thought
beavers were a nuisance.

B. Beavers’ Amazing Building Skills
C. The Many Enemies of Beavers
D. Beavers’ Ponds: Homes for Other Creatures
