六、阅读理解。
Long ago, when the god first planted a tree in the garden, it was full of energy and kept moving. Then the god pulled (拔) the tree out and planted it upside down (颠倒) to make sure it stayed in one place. What’s the tree It’s the baobab tree, also called the monkey bread tree, the bottle tree or others.
The baobab tree is a strange-look tree that grows in Africa and Australia. Just like its name “the bottle tree”, it looks like a large bottle. Some grow as tall as a 16-floor building. During the dry season, these trees are standing there without leaves, and look like trunks (树干) sticking up in the air. But when the rainy season comes, leaves appear and then flowers come out. Later, the flowers can turn into fruit.
The baobab is called “the tree of life”, because it can live for more than 1,000 years. In the dry land, the baobab can pull in and hold 1,000 gallons of water. Thirsty people can drink the water stored in the tree. The fruit, monkey bread, is good to eat. Baobab leaves are a kind of medicine (药). People can use the bark (树皮) to make paper or cloth. When a baobab gets old, its trunk becomes hollow. An old tree can hold many people. The local people often build their houses inside these trunks. It is such a useful tree that some people can hardly live without it.

Say the word shark to someone on the beach and you are sure to get a reaction(反应). Sharks have been the most dangerous predator(捕猎者) of ocean. Sharks are fish. 6 They can be found in oceans all over the world, and they have also been found in some rivers and lakes.
One difference between most other fish and a shark is that most fish have bones(骨头) and a shark has cartilage(软骨). 7 Another difference is that the shark is only able to swim forward, while most fish can swim forwards and backwards. Fish also generally have slippery scales(滑溜的鱼鳞), while a shark has rough scales that feel like sandpaper.
8 In fact, there are about 368 different types. The differences include color, habitat, behavior, and size. Sharks are also known for their very sharp teeth. 9 But they swallow large chunks of food. They have five rows of teeth. If a tooth is broken, a new one grows.
Sharks are carnivores, meaning that they eat meat. 10 In fact, chances of getting stung by a bee or getting hit by lightning are greater. Even so, experts say it is important to keep an eye out for sharks when swimming in the ocean.
A．But they do not normally attack(攻击) people.
B．Sharks can cause fear like no other fish in the sea.
C．They do not use their teeth to chew their food.
D．Cartilage is tough, but it is not as strong as bone.
E．Some act alone, while some hang out in groups.

When we talk of things that grow on the ground and have green leaves (叶子), but there are plants that do not look like other plants. Some of these are called fungi (真菌). Fungi may appear almost everywhere. They usually grow in wet places where they can get food and water easily. Because fungi do not have green leaves to make food for themselves, and they must take their food from animals, other plants or water. Mushrooms (蘑菇) are the best-known fungi.
There are many kinds of mushrooms. For example, we can find cauliflower mushrooms in forests from July to October. They can grow to be as heavy as fifty pounds. They grow at the foot of trees. Squirrels’ (松鼠的) bread is another kind of wild mushroom. These fungi look like small bread. Squirrels can easily eat them or take them to their holes to eat later. The mushrooms in food stores are grown carefully. People can eat them safely. People should never touch or taste wild mushrooms, because some of them are poisonous. Even less dangerous ones can still make a person feel bad.
