The Blue Whale
The blue whale is the largest animal that has ever lived on Earth. It is even bigger than the biggest dinosaurs. An adult blue whale can be 30 meters long and weigh 150 tons—that's as heavy as 30 elephants!
Blue whales live in oceans all over the world, except the Arctic Ocean. They swim in groups and communicate with each other using low sounds. These sounds can travel thousands of kilometers under water.
Unlike many other whales, blue whales eat very small sea animals called krill. They can eat up to 4 tons of krill in one day. Mother blue whales feed their babies with milk, just like land animals.
Blue whales are amazing, but they are in danger. There are not many left in the world. We must protect them and their home in the ocean.

Bamboo: A Useful Plant
Bamboo is a very special plant. It grows in many parts of the world, especially in China. There are over 1,000 kinds of bamboo.
One amazing thing about bamboo is how fast it grows. Some bamboo can grow almost one meter in one day. It is one of the fastest-growing plants on Earth. Bamboo is also strong. People use it to build houses, make furniture, and even musical instruments.
Bamboo is important to animals too. Pandas love to eat bamboo shoots. Many birds build their nests in bamboo forests. Some insects live on bamboo leaves.
In China, bamboo is a symbol of goodness and strength. You can see bamboo in many Chinese paintings. It is a popular plant in gardens because it looks beautiful and grows quickly.
（ ）36. How fast can some bamboo grow

Bees and Pollination
Bees are small but very important insects. They help plants grow by carrying pollen from one flower to another. This process is called pollination. Without pollination, many plants cannot make fruit or seeds.
A bee has special hair on its body that collects pollen. When it lands on a flower, pollen sticks to its hair. Then, when the bee flies to another flower, some of the pollen falls off. This helps the new flower make seeds.
Bees live in groups called hives. Each hive has a queen bee, worker bees, and drone bees. Worker bees are the ones that collect pollen and make honey. They visit hundreds of flowers every day.
Bees are important to humans too. Many of the fruits and vegetables we eat, like apples and tomatoes, need bees to pollinate them. Without bees, we would have fewer foods to eat. We must protect bees and their homes.
（ ）41. What do bees carry from flower to flower
A. Fruit. B. Seeds.
C. Pollen. D. Honey.
（ ）42. What is pollination
A. Making honey. B. Carrying pollen between flowers.
C. Building hives. D. Eating fruits.
（ ）43. What do worker bees do
A. They are queens. B. They collect pollen and make honey.
C. They eat fruit. D. They fly away from the hive.
（ ）44. Why are bees important to humans

C. They help grow fruits and vegetables. D. They are small insects.
（ ）45. What would happen without bees
A. We would have more food. B. We would have fewer foods.
C. Flowers would grow better. D. Pollination would happen faster.
D
Amazing Plants: The Redwood Tree
Redwood trees are some of the most amazing plants in the world. They grow in California, USA. These trees are famous for being very tall and very old.
Some redwood trees are over 110 meters tall—that's taller than a 30-story building! They can live for over 2,000 years. One redwood tree in California is about 2,200 years old. It was alive when Jesus was born!
Redwood trees have thick bark that protects them from fires. This bark can be up to 30 centimeters thick. The wood of redwood trees is also very strong and is used to make buildings and furniture.
Many animals live in redwood forests. Birds build nests in the branches, and deer live in the shade under the trees. These forests are important ecosystems for many living things.
Today, redwood trees are protected by law. People cannot cut them down easily. This helps ensure that these amazing trees will live for many more years.

Finally, bamboo. This tall, green plant grows in many parts of Asia, especially in China. It doesn't need much except sunlight and water to grow. Bamboo's special feature is its growth speed—up to 1 meter per day. It's important for pandas, who eat almost nothing else.

My Favourite Amazing Animal
My favourite amazing animal is the cheetah. It is known as the fastest land animal, which can run at speeds up to 120 km/h. What's amazing is that it can accelerate faster than most cars.
Cheetahs mainly live in Africa, especially in grasslands. They have a slender body and spotted fur, which helps them hide when hunting.
We need to protect cheetahs because their numbers are decreasing. Loss of habitat and lack of food threaten their survival. Protecting them means keeping the balance of nature.
