Answer:

Polar bears are large carnivorous mammals that are native to the Arctic regions. They are the largest land predator and can grow up to 10 feet long and weigh up to 1,500 pounds. Their fur is white, which helps them blend in with their snowy surroundings, and their skin is black, which helps them absorb the sun's heat.

Polar bears are well adapted to their cold environment. They have a thick layer of blubber to keep them warm, and their fur is water-repellent to keep them dry. They are excellent swimmers and can swim for long distances in the icy water.

Polar bears are also very patient hunters. They often wait by a seal's breathing hole in the ice, waiting for it to surface so they can grab it with their powerful jaws. They are also known to hunt other prey, such as walruses and beluga whales.

Unfortunately, polar bears are facing many challenges due to climate change. As the Arctic ice melts, it becomes harder for them to find food and habitat, and their populations are declining. Conservation efforts are underway to protect these magnificent animals and their fragile ecosystem.

B. Read the text.

Climate Change

Polar bears live on the Arctic sea ice. It is their natural habitat. From these ice platforms, they can catch seals to eat. The ice is very important for polar bears, but sadly it is disappearing because of climate change. The world is getting warmer and the Arctic ice is melting. If the ice disappears, polar bears will have a hard time finding food.

If we don't try to stop climate change, polar bears and other wild animals are going to become extinct. We need to protect these endangered species. They are all an important part of the natural world.

Answer:

Biến đổi khí hậu

Gấu Bắc Cực sống trên băng biển Arctice. Đó là môi trường sống tự nhiên của chúng. Từ những nền băng này, chúng có thể bắt hải cẩu để ăn. Băng là rất quan trọng đối với gấu Bắc Cực, nhưng đáng tiếc là nó đang biến mất vì biến đổi khí hậu. Thế giới đang ngày càng ấm lên và băng Arctice đang tan chảy. Nếu băng biến mất, gấu Bắc Cực sẽ gặp khó khăn trong việc tìm kiếm thức ăn.

Nếu chúng ta không cố gắng ngăn chặn biến đổi khí hậu, gấu Bắc Cực và các loài động vật hoang dã khác sẽ trở thành loài tuyệt chủng. Chúng ta cần bảo vệ những loài bị đe dọa này. Chúng tất cả đều là một phần quan trọng của thế giới tự nhiên.

H. Discuss these situations in pairs. Write sentences to describe them in your notebook. What will happen if...

(Thảo luận những tình huống này theo cặp. Viết câu để mô tả chúng trong sổ ghi chép của bạn. Chuyện gì sẽ xảy ra nếu...)

1. the climate continues to change?

2. the polar bears’ habitat disappears?

3. polar bears can't catch enough seals?

4. people protect polar bears?

5. polar bears become extinct?

6. polar bears try to find food in towns?

Answer:

1. If the climate continues to change, the planet will face severe consequences such as rising sea levels, extreme weather conditions, and loss of biodiversity.

2. If the polar bears' habitat disappears, they will be forced to move to other areas in search of food, which may lead to conflicts with other animals and a decline in their population.

3. If polar bears can't catch enough seals, they will become weak and may eventually die due to starvation or malnutrition.

4. If people protect polar bears, their population will increase, and their habitat will be conserved, which will benefit the ecosystem as a whole.

5. If polar bears become extinct, it will disrupt the food chain and lead to a significant ecological imbalance, and their loss will be irreversible.

6. If polar bears try to find food in towns, they may come into conflict with humans, which may lead to dangerous situations for both humans and bears. Additionally, they may become dependent on human food, which could negatively affect their health and behavior.
