Then it looks full of life again. ④The baobab tree is vital to local people and animals. People use the baobab’s bark (树皮) to make strong ropes and soft cloth. Its fruit is eatable and rich in vitamin C, which is good for health. Animals like baboons (狒狒) and elephants also rely on (依靠) it. They eat its fruit and leaves, and some even hide from the sun under its big branches (树枝) . ⑤Sadly, baobab trees are now in danger. Deforestation (森林砍伐) and climate change make their numbers drop.

It’s one of the strangest and most amazing trees on earth. It mainly grows in Africa and Australia. ②The baobab has a very thick trunk. Some trunks are as wide as 10 metres—just like three cars parked side by side! This thick trunk isn’t only for looks. It can store lots of water inside. This special ability helps the baobab live easily in dry places. ③Baobab trees live a long time. Many are over 2,000 years old, so they have seen hundreds of years of history. Their leaves are usually small. In the dry season, the leaves fall off to save water. When the wet season comes, the tree grows fresh green leaves and blooms beautiful white flowers. Then it looks full of life again. ④The baobab tree is vital to local people and animals. People use the baobab’s bark (树皮) to make strong ropes and soft cloth. Its fruit is eatable and rich in vitamin C, which is good for health. Animals like baboons (狒狒) and elephants also rely on (依靠) it. They eat its fruit and leaves, and some even hide from the sun under its big branches (树枝) . ⑤Sadly, baobab trees are now in danger. Deforestation (森林砍伐) and climate change make their numbers drop. Luckily, scientists are working hard to study them. They want to find good ways to protect the baobab, so future kids can see this amazing tree too. 1．What do we know about baobab trees from the passage? A．They only grow in Africa.
