IV. 阅读理解
Can you say the meaning of “Zero” Can you do addition and subtraction (加减法) Most people can. But do you know bees can do these things too A study shows that bees have even greater math abilities. After some training, they can know the difference between even numbers (ending in 0, 2, 4, 6 and 8) and odd numbers (ending in 1, 3, 5, 7 and 9).
返回
Some Australian scientists put up different cards with an odd or even number of triangles ( 三角形). They used the numbers 1 to 10. Then they trained the first group of bees to choose odd numbers and the second group to choose even numbers. If a bee flew to the right card, it would get sugar water. Instead, it got bitter (苦的) water.
返回
In a short time, all the bees knew what odd numbers or even numbers were. They could fly to the right numbers 80% of the time. After that, the scientists added new cards with the numbers 11 and 12. The bees never saw the numbers before, but they could choose rightly 70% of the time. Surprisingly, the bees even learned odd numbers more quickly than people.
返回
How did the bees learn the numbers so fast Scientists didn’t have a clear idea. But they believe if they find the answer, it will help them build better computers. After all, a bee’s brain is about 86,000 times smaller than ours!

V. [2025 石家庄长安区期中] 阅读表达
Twenty years ago in Costa Rica, three girls found a baby sloth (树懒) on a road. The little animal’s mother was killed (杀死) by a car. These girls took the baby sloth to Judy, the owner of a hotel. Judy wanted to help, but she didn’t know how to look after the sloth, so she told the zoo. With the help of the zoo, Judy took good care of the baby sloth. She named it Buttercup.
返回
After her first success, more people brought Judy wounded (受伤的) sloths or baby sloths they found. Judy then opened a help center. Today, the help center has saved more than 500 sloths.
Sloths live in the forests of Central America. We can also see them in South America. They hang onto the trees with their claws (爪子). There are two main types of sloths.
返回
You can know them by the number of their claws. Sloths hardly move. They spend most time sleeping in the trees.
But now, with the increase of population, human beings cause a lot of problems for these slow and quiet animals. The main problem is that the forests are becoming smaller and smaller. When trees are cut down, sloths will fall and hurt themselves. Some sloths live near human beings and they sometimes are hit by cars or killed by dogs.
