Many animals around us are smart. Let’s get to know some of them.
Dolphins are smarter animals in the sea. Researchers put sea animals to a test. In the test, the researchers made red marks on the animal’s bodies and took them in front of a mirror. Many sea animals either ran away or fought with the ones in the mirror. However, when the dolphins saw themselves in the mirror, they tried to clean the red marks off their bodies. So the researchers believed that the dolphins knew the ones in the mirror were just themselves.
Bees work hard, and they are smart enough to learn something. Researchers found a group of bees and taught them to tell which horizontal line (水平线) was higher than the other. If they could find the higher line, they would get sugar as a prize. After training for a period of time, the researchers tested the bees. To their surprise, the bees found the higher horizontal line quickly and got sugar. Instead, when the researchers showed them vertical lines (垂直线), the bees simply flew away, because they knew there was no way to get sugar.
Chimpanzees (黑猩猩) are very human-like. They can learn fast and well. Researchers showed the numbers from one to nine on the screen. Chimpanzees and some college students were asked to remember where the numbers were after watching the numbers in less than a second. The adult chimpanzees and the college students performed almost the same, but the young chimpanzees performed much better. It was amazing.

All our food comes from the soil(土壤). Some of us eat meat, but animals live on plants. If there are no plants, we will have no animals and meat. So the soil is necessary for us to live.
The top of ground is usually covered with grass or other plants. Plants grow in soil, which has a dark color. This dark soil is humus. Dead leaves, dead plants and animals’ waste make it, but this takes a long time. When the humus has been made, plants can grow well in it.
All soil needs food. If we don’t give it any, the plants will be weak. Animals’ waste is the best food for the soil, but chemical fertilizers (化肥) are also very useful. The same crop (庄稼) should not be grown in the same place every year; it is better to have a different crop. A change of crop and the use of a good fertilizer will keep the land in good condition.
When the soil is dry, the wind blows it away. Sometimes heavy rain carries the humus down to a river. People should grow more and more trees and grass to stop wind from carrying the humus (腐殖土壤)away. It takes hundreds of years to make humus, and so we must save every bit of it. Without soil, where can we grow food?
1. From the text, we know people live on ___________.
A. animal B. plant
C. meat D. soil
2. We should ___________ to keep the soil.
A. give more fertilizers
B. grow a different crop every year
C. make more humus
D. grow more trees and grass
3. We should save every bit of humus, because ___________.
A. it takes a long time to make humus
B. sometimes the wind will blow the dry soil away
C. the chemical fertilizers are expensive
D. animals waste is the best food for the soil
4.From the passage, we know that soil is ___________ to people.
A. not helpful B. necessary
C. not important D. harmful
