12. Read the text and entitle it.

On November 24, 2004 the United Nations warned that the world was facing a “unique development challenge” with acceleration in the spread of AIDS. New data revealed there are nearly 40 million HIV sufferers worldwide. Of these 3 million will die of AIDS this year, a record toll in the 23-year history of the killer virus.

The report says Sub-Saharan Africa remains by far the worst-affected region in the world. In South Africa 5.3 million people are infected, with “no sign yet of a decline in the epidemic.” India has the second largest number of HIV sufferers in the world (5.1 million), while East Asia has seen a 56 percent increase in HIV cases, mainly attributable to an explosive rise in China. Women now constitute over half of all new cases contracting HIV/AIDS due to poor sexual education, the sex trade, unprotected sexual intercourse, and a greater natural susceptibility to contract the virus than men.

However, if you are diagnosed with HIV, your physical health is not the only issue you have to deal with. Along with the physical illness are mental health conditions that may come up. Mental health refers to the overall well-being of a person, including a person's mood, emotions, and behavior. HIV/AIDS can have a major impact on many parts of human life. People with HIV and those close to them are subject to many things that may affect their mental health.

Many people are surprised when they learn that they have been diagnosed with HIV. Some people feel overwhelmed by the changes that they will need to make in their lives. It is normal to have strong reactions when you find out you are HIV positive, including feelings such as fear, anger, and a sense of being overwhelmed. Often people feel helpless, sad, and anxious about the illness.

Although the society doesn’t forget people affected with this devastating disease. The red ribbon, a ribbon colored red, is the symbol of solidarity of people living with HIV/AIDS.

The New York artists created the Red Ribbon Project in 1991. The artists wished to create a visual symbol to demonstrate compassion for people living with AIDS and their caregivers. The color red was chosen for it as the connection to blood and the idea of passion - not only anger, but love, like a valentine. First worn publicly by Jeremy Irons at the 1991 Tony Awards, the ribbon soon became renowned as an international symbol of AIDS awareness, becoming a politically correct fashion accessory on the lapels of celebrities. The Red Ribbon continues to be a powerful

force in the fight to increase public awareness of HIV/AIDS and in the lobbying efforts to increase funding for AIDS services and research.

13. Pairs/Groups write down questions based on

the article. Ask them your partner.

14. Give a short talk on:

• The present-day situation in spreading of AIDS.

• Mental health conditions of an infected person.

• Red Ribbon project history.

15. Write a letter to the President of the Republic of Kazakhstan explaining your concerns for AIDS victims and explaining what you feel the leader of the free world should do.

16. Role-play dialogue.

You came to the blood transfusion center. You are going to donate blood. Ask the doctor about the measures they take to prevent everybody to catch HIV. Your goal is to be as sure as possible in your safety. The doctor’s aim is to make you sure that only in their center they take maximum care about donators.

17. Write a composition/ presentation.

You are the doctor sent to some high school to tell students about the measures to prevent catching of HIV. Prepare your speech to tell them as much as possible.

UNIT 10

Microbiology

Say in your words what microbiology is. How many areas of microbiology do you know? What is the main subject of microbiological research?

1. Read this text.

The fantastic world

Microbiology is the study of microorganisms, which are microscopic and unicellular organisms. This includes eukaryotes such as fungi and protists, and prokaryotes. Viruses, though not classed as living organisms, are also studied. Microbiology typically includes the study of the immune system, or Immunology. And immune systems obviously interact with pathogenic microbes.

Microbiology includes virology, mycology, parasitology, bacteriology and other branches. Microbiological procedures usually must be aseptic, and use a variety of tools such as light microscopes with a combination of stains and dyes, agar plates in petri dishes, biochemical test and running tests against particular growth conditions.

Microbiology is researched actively. Many microbes are responsible for beneficial processes such as industrial fermentation, antibiotic production and others.

Bacteria can be used for the industrial production of amino acids. Corynebacteriumglutamicum is one of the most important bacterial species with an annual production of more than two million tons of amino acids. Microorganisms produce a variety of biopolymers, such as polysaccharides, polyesters, and polyamides. Microorganisms are used for the biotechnological production of biopolymers with tailored properties suitable for high-value medical application such as tissue engineering and drug delivery.

Microorganisms are beneficial for microbial biodegradation of domestic, agricultural and industrial wastes. The ability of each microorganism to degrade toxic waste depends on the nature of each contaminant.

There are also various claims concerning the contributions to human and animal health by consuming probiotics (bacteria potentially beneficial to the digestive system) and/or prebiotics (substances consumed to promote the growth of probiotic microorganisms). Recent research has suggested that microorganisms could be useful in the treatment of cancer.
