Do animals communicate with each other How do they communicate with others I did some research and, to my surprise, I learned that all animals communicate. They don’t use language, but they send messages (信息) to each other. Animals communicate with each other in three main ways: through sounds, smells, and body language.
The alarm (警报) call is one way. When an enemy is near, animals send out a warning sound. Others hear it and run to a safe place, or get together to fight the enemy. Whales (鲸鱼) are famous for their talent to communicate from far away with special sounds. In their own social groups, whales understand what they’re saying to each other.
Smell is another popular way for animals to communicate. Some animals such as the amoeba (变形虫) send out a smell to tell other amoebas it’s going to have babies. Skunks send out an odour when they feel they are in danger.
Skunk
Many animals use body language to communicate. Chimpanzees (黑猩猩) touch hands when they meet. A happy dog moves its tail from side to side. Even people understand this form of dog body language.
People develop their own ways of communicating, using words and sentences. But if you watch other animals carefully, you quickly come to understand that they also have ways of sending their messages.

A．By listing numbers. B．By telling a story. C．By asking questions. D．By showing an old saying.

Bananas don’t grow on trees. They grow on a stalk (茎) that looks just a little like a stalk of corn. The stalk is soft enough to be cut with a knife.
It takes about a year before bananas are ready to be picked. Some are as small as fingers. 6 Some banana plants grow as tall as a house—even taller!
7 Some never get sweet, and they are cooked as a kind of vegetable.
The tasty fruit doesn’t come from a seed but from a root planted deep in the ground.
First a stalk pushes up into the air. 8 In the beginning, the banana plant grows very fast—sometimes as much as the length of your feet in one night. Soon, sweet-smelling flowers come out, and when their flowers drop off, bananas begin to grow. As they get bigger, bananas start turning up (卷起来). 9
Bananas are ready to eat when they turn soft and yellow. Bananas are picked long before this—when they’re hard and green. This is because bananas have to travel many miles before they arrive at a store. 10 There are special boats just for bananas and special trains that keep them just cool enough so that they will get ripe (成熟的) while traveling. If bananas are picked when they are ripe, they will spoil on the way.
A．Not all bananas are eaten as fruit.
B．Then the leaves grow.
C．A long time is spent picking bananas.
D．It looks as if they’re growing upside down!
E．Others are as long as men’s arms.
F．On boats and trains bananas travel all over the world.

Plants are amazing because they make their own food using three simple things. How do they make it Let’s see an experiment （实验）.
There’s a green plant in a glass box with some soil （土壤）. It’s in the box for a reason. We can learn about the things it needs to live which are water, CO2 and the light to make its own food.
In this experiment, light is like the sun. If we turn down the light for some time, and then the plant can’t grow. At other times if we cut down the CO2, it won’t live either. Lastly, if the plant doesn’t have enough water for a long time, it will die soon. So it shows plants must have these three things to grow.
You may wonder how they make their own food using the three things. First, plants take in the water and CO2. Then their leaves absorb （吸收） sunlight. Finally, the plants make the sugar as its own food and make O2 that humans need. It truly improves our environment, because plants cut down the CO2 in the air and give us more O2. Besides, scientists have also asked us to go outside and look at green plants more to improve our eyesight.
How do plants make their own food
The experiment Put a green plant into a 21 .
The things plants need The plants has water, CO2 and 22 to make its own food in the box.
The 23 of making food First, plants take in water and CO2. Then their leaves absorb sunlight. Finally, they make the sugar as its own food.
