II. Read and translate the text. What is Life?

Before moving on to the development of microscopic organisms on Earth, we must first describe the characteristics of life. All matter, both living and non-living, is composed of miniature chemical building blocks called atoms. Your body contains billions of hydrogen, oxygen, nitrogen, phosphorus and carbon atoms. The computer you are looking at is also composed of billions of various atoms. However, there is a very important distinction between yourself and your computer – you are alive.

What is life? What does it mean do be alive? How is something made “living”? These are all pertinent questions when discussing the origin of life. Scientists have identified seven basic characteristics of life. For something to be described as living, that something must display all seven of these characteristics. Although many different people have many different opinions about what “living” means, the following characteristics were designated “characteristics of living things” with the consensus of the scientific community.

III. What is missing? Find the words in reading:

1. Before _______ to the development of microscopic organisms on Earth we must first describe the characteristics of life. 2. Your body ______ billions of hydrogen oxygen atoms. 3. The computer is also _____ of various atoms. 4. There is a very important _____ . 5. What does it _____ to be alive? 6. Something must _____ all seven of these characteristics. 7. The following “characteristics of living things”_______? 8. Living organism _____ traits from the present organisms. 9. All living things respond to stimuli in their _____ .

IV. Answer the questions:

1. What is it necessary to do before moving on to the development of life?

2. What is both living and non-living composed of?

3. What does your body composed of?

4. What does it mean to be alive?

5. What have scientists identified?

6. What are the characteristics of living things?

Grammar and speaking:

The verb “to be”; to be-construction, third person singular of a verb in Present Indefinite; types of questions; Active Voice and Passive.

I. Find examples of Indefinite Active and Past Indefinite Passive in the text about life.

II. Find in the text the forms of the verb “to be” and use them in your own sentences.

III. Compare two Voices and translate sentences:

1. Several recent studies showed a connection between stress and illness.

2. Cellular responses center around the activities of T-lymphocytes.

3. Lack of sufficient insulin results in diabetes.

4. People vary in their reaction to different antigens.

5. The surgeon is assisted by a large staff.

IV. Work in pairs. Read the characteristics of life and ask questions.

V. Take part in the discussion according to the situation given.

Using the characteristics in ex 3, one can categorize things as living or non-living. Imagine if you were a biologist who had never been to Earth before. You have been sent on a mission to determine whether these things called “trees” are alive. How do trees satisfy the seven characteristics of living things?

1. …Are Composed of Cells. Cells are the basic components of all living things. Some organisms are single- celled, like bacteria, or multi-celled, like humans.

2. … Require Energy. Living organisms require energy, usually in the form of ATP. They use this energy-requiring activities such as metabolism and locomotion.

3. … Reproduce. All living organisms reproduce, either by sexual or asexual means.

4. … Display Heredity. Living organisms inherit traits from the parent organisms that created them.

5. …Respond to Stimuli. All living things respond to stimuli in their environment.

6. …Evolve and Adapt. Living organisms adapt to their environment and evolve.

7. … Maintain Homeostasis. All living things maintain a state of internal balance.
