                                                        BACTERIA AND VIRUSES

Both bacteria and viruses can cause diseases, but they are different in many ways. Bacteria are living organisms. They can live in many places, such as soil, water, and the human body. The smallest bacteria are about 0.4 micron* in diameter. Some bacteria in our bodies are helpful, but some can cause infectious diseases such as tuberculosis** or food poisoning. Antibiotics are often used to treat infections caused by bacteria.

*7 metre = 1 million microns 

**a serious lung disease

Viruses are tiny germs that cause diseases in people, animals, and plants. They can cause a range of illnesses, from the common cold or the flu to more serious diseases such as AIDS and Covid-19. As they are very small (0.02 to 0.25 micron), viruses can get into our bodies easily. They are not living things, so they need to enter our bodies to become active. Then, they start to grow and cause the infected cell to make millions of copies of the virus. Vaccines are often used to prevent the spread of diseases caused by viruses.

Read the passage and check (ü) whether the following statements are true (T) or false (F).

Energy makes change; it does things for us. It moves cars along the road and boats over the water. It bakes a cake in the oven and keeps ice frozen in the freezer. It plays our favourite songs on the radio and lights our homes. Energy makes our bodies grow and allows our minds to think. Scientists define energy as the ability to do work. People have learned how to change energy from one from one form to another so that we can do work more easily and live more comfortably.

All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups – renewable and nonrenewable. Renewable energy source is an energy source that can be replenished in a short period of time. Nonrenewable energy source is an energy source that we are using up and cannot recreate in a short period of time.

Renewable energy sources include solar energy, which comes from the Sun and can be turned into electricity and heat. Wind, geothermal energy from inside the Earth, biomass from plants, and hydropower and ocean energy from water are also renewable energy sources.

However, we get most of our energy from nonrenewable energy sources, which include the fossil fuels – oil, natural gas, and coal. They’re called fossil fuels because they were formed over millions and millions of years by the action of heat from the Earth’s core and pressure from rock and soil on the remains of dead plants and animals. Another nonrenewable energy source is the element uranium, whose atoms we split (through a process called nuclear fission) to create heat and ultimately electricity.

Question: Renewable energy can be turned into electricity and heat.

A. True

B. False

Polar explorers can cope with temperatures of 1________, but only if they keep warm. Most people will collapse if their body temperature drops by only 2________, and if it drops by 3________, they'll die. Heat can be just as dangerous. Temperatures of 35°C are safe, provided humidity is not above 4________. High altitudes are dangerous too. We pass out when the pressure falls below 5________  of normal atmospheric pressure. This happens at about 6________   metres. Climbers can go higher because their bodies gradually get used to it, but no one survives for long at 8,000 metres. At high altitudes, lack of oxygen is another problem. At ground level, about 7______ of the air is oxygen. If that falls below 8________ , we die.

Choose the best anwers for the following questions.

The generation gap, which refers to a broad difference between one generation and another, especially between young people and their parents, usually leads to numerous conflicts. Such family conflicts can seriously threaten the relationship between parents and children at times.

It goes without saying that, however old their children are, parents still regard them as small kids and keep in mind that their offspring are too young to protect themselves cautiously or have wise choices. Therefore, they tend to make a great attempt to help their children to discover the outside world. Nevertheless, they forget that as children grow up, they want to be more independent and develop their own identity by creating their own opinions, thoughts, styles and values about life.

One common issue that drives conflicts is the clothes of teenagers. While teens are keen on wearing fashionable clothes which try to catch up with the youth trends, parents who value traditional clothes believe that those kinds of attire violate the rules and the norms of the society. It becomes worse when the expensive brand name clothes teens choose seem to be beyond the financial capacity of parents.

Another reason contributing to conflicts is the interest in choosing a career path or education between parents and teenagers. Young people are told that they have the world at their feet and that dazzling future opportunities are just waiting for them to seize. However, their parents try to impose their choices of university or career on them regardless of their children's preference.

Indeed, conflicts between parents and children are the everlasting family phenomena. It seems that the best way to solve the matter is open communication to create mutual trust and understanding.

Question 3. What do parents usually do to help their children as they are young?

A. They prepare everything for their children.

B. They take care of their children carefully.

C. They encourage their children to explore the outside world.
