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.

Read the text. Match the headings (1-3) with the paragraphs (A-C).

1. Comparing to others             2. Lack of understanding                3. Lack of interaction 

In most cultures, there is a generation gap between parents and their children. There are many reasons for this gap. Below are three of them.

A. _______________________________________

As each generation is strongly influenced by changes in society, parents and children may see the world differently. In addition, different lifestyles make it difficult for parents and their children to fully understand each other's way of thinking. Many adult children even cut all ties with their parents.

B. _______________________________________

Busy work and school schedules often prevent parents and children from spending time together. After along and stressful day at work, parents come home, often feeling exhausted, and have little time to spend with their children. This leads to a lack of communication and widens the generation gap.

C. _______________________________________

Many parents keep comparing their children to other children, or even to how they behaved as children. They think it is good for their children to see these good examples and try to improve. However, this only makes the gap wider and causes their children to lose confidence in themselves. Some children may even start hating those people that they are compared to.
