X Read the passage. Answer the questions below.
Scientists have discovered that the ozone layer is getting thinner. Some predict that the sun’s rays will cause a sharp increase in deaths from skin cancer over the next fifty years. These harmful rays can also damage the eyes, create wrinkles, and cause other health problems.
The stratosphere contains a form of oxygen called ozone. Ozone is a molecule composed of three oxygen atoms. The chemical formula of ozone is 03. Oxygen molecules make up about 21% of all gases in the Earth’s atmosphere. They consist of two atoms of oxygen and are labeled 02. Most ozone found in our atmosphere is formed by an interaction between oxygen molecules and ultraviolet radiation (UV) from the sun. When ultraviolet radiation hits an oxygen molecule, it may cause the molecule to break apart into single atoms of oxygen. These single atoms are very reactive, and a single oxygen atom can combine with a molecule of oxygen to form ozone.
1.What do people say about the rate of deaths from skin cancer in the future?
=> Some predict that the sun’s rays will cause a sharp increase in deaths from skin cancer over the next fifty years. These harmful rays can also damage the eyes, create wrinkles, and cause other health problems.
2. How many oxygen atoms are there in a molecule?
=> Oxygen molecules make up about 21% of all gases in the Earth’s atmosphere
3.What elements participate in the formation process of ozone?
=> Most ozone found in our atmosphere is formed by an interaction between oxygen molecules and ultraviolet radiation (UV) from the sun.
4.What happens when an oxygen molecule and an ultraviolet radiation hit each other?
=> When ultraviolet radiation hits an oxygen molecule, it may cause the molecule to break apart into single atoms of oxygen
5.What is the feature of single atoms?
=> These single atoms are very reactive, and a single oxygen atom can combine with a molecule of oxygen to form ozone.

Do you think the animals can understand each other? The answer is yes. They can communicate to each other by signs and sounds. For example, dogs communicate in many ways. They not only bark, even they howl, growl, snarl, and whine. They lift a paw, or bare their teeth. Other dogs can understand what these sounds and actions mean_.
Animals communicate with each other not only with sounds and movements but with smell. Most animals that live in herds depend on smell to keep together. And, of course, we know how dogs recognize each other by smell.
Apes are supposed to be among the most intelligent of animals, yet, they really have no better “language” than other animals. They make many sounds and expressions of the mouth to communicate their feelings of anger or hunger or joy, but they have nothing like the words of human speech.
By the way, unlike human beings who have to learn how to talk, apes and other animals know their “language” by instinct. They will make the right kind of cries and sounds and expression even if they have never seen another animal like themselves before.
Birds, however, learn their way of singing, at least in part. That is why a sparrow brought up among canaries will try to sing like one. It has been learning the wrong “language”!
