Mark the sentences (1-5) as T (true), F (false) or DS (doesn't say). 1. Gregor Mendel was the first person to study genetics.

I suppose everybody considers modern technologies to be significant in our everyday life. Nowadays people can't imagine their lives without new devices. They are everywhere in our everyday life.
Almost nobody washes the clothes by hand. Almost everybody has a mobile phone. All modern offices are equipped with computers, scanners, printers, and other self-operating machines. The rapid rise of using the Internet is the reality of our time.
But I think modern technologies can be dangerous to some extent for people because mankind becomes too dependent on them. We and our children depend on how 'clever' appliances work. But, it isn’t always healthy to use them for a long time. Sitting long hours in front of the computer is bad for the eyes and causes back problems. They say cell phones contain negative vibes that influence human organism.
Most people are sure that new technologies are good. Thanks to computers and the Internet we can find more educational resources in no time. Such electronic items as vacuum-cleaner, washing machine, microwave, dishwasher, blender and a lot of others have made our life easier. It's really true. We can't but agree to it. I am not against new technologies. But in my opinion, nowadays the modern world relies too much on them.
In conclusion, I’d like to say that technological progress can be dangerous to some extent for humankind and for surrounding nature too. So it's necessary to make modern devices safer and cheaper for people to use them and make the people's life happier and more pleasant.
Any list of the greatest thinkers in history will contain the name of the brilliant physicist Albert Einstein. His theories of relativity led to entirely new ways of thinking about time, space, matter, energy, and gravity. Einsteins work led to such scientific advances as the control of atomic energy and to some of the investigations of space. Einstein was born in Ulm, Germany, on March 14, 1879, of Jewish parents. He was a shy and curious child. He attended a Munich elementary school where he showed an interest in science and mathematics but did poorly in other areas of study. He finished high school and Technical College in Switzerland. In 1905, at the age of 26, he published five major research papers in an important German physics journal. He received doctorate for the first paper. Publication of the next four papers forever changed mankinds view of the universe. One of his papers laid the foundation for the photon, or quantum, theory of light. Television and other inventions are practical applications of Einsteins discoveries. In his works Einstein showed that time and motion are relative to the observer, if the speed of light is constant and natural laws are the same everywhere in the universe. His fourth paper was a mathematical addition to the special theory of relativity. Here Einstein presented his famous formula E = mc2, known as the energy-mass relation. In 1916 Einstein published his general theory of relativity. World-wide fame came to him in 1919 when the Royal Society of London announced that his general theory of relativity had been confirmed. He was awarded the Nobel Prize for physics two years later. In 1940 he became an American citizen. Einstein died in Princeton, on April 18, 1955.
