Dinosaurs (lived)  on our planet 65,000,000 years ago! The first dinosaurs (looked) like big lizards. Many of them had short tails, big heads (and)

walked on four legs. Most dinosaurs were herbivores, which means that they only ate plants. Some of these dinosaurs were very (small) but other kinds of dinosaur were bigger and heavier and were carnivores, which means that they ate meat. Dinosaurs lived (in) warm forests where there were lots and lots (of) plants and water. But about 60,000,000 years ago, some people say (the) weather on Earth suddenly got colder and drier. Many plants (that) dinosaurs liked to eat stopped growing, which was a terrible problem for these animals, so soon dinosaurs disappeared too.

Today, people sometimes (find) dinosaur teeth in rocks or under the ground. Dinosaurs are now extinct, but you can learn about (them) in special science museums or when you watch scary dinosaur films (on) TV.

“What is happening to our young people? They disrespect their elders; they disobey their parents. They ignore the law. They riot in the streets, inflamed with wild notions.Their morals are decaying. What is to become of them?” Plato 4th Century!!  (цитата)

What kind of problems do teenagers have nowadays?
Young people can meet difficulties everywhere: at home, at school, in the street. They face to different problems. They are  as school problems, emotional problems, health problems, at home with parents ,     misunderstanding  ,  smoking  ,    using drugs   ,   using alcohol drinks  ,    relationships with lovers.  The teenager is kind enough. Someone  tries to get  good education  nowadays.
Someone is sure that the most important thing in life is health, freedom and the ability to adapt.
Someone  go in for different kinds of sport.  Someone enjoy drugs, alcohol, and smoking. Someone try to make the around world better.
I think that  youth is a very important period in the life of man. This is the time when a  youth  tries to determine  themsel fplace in this world.
Young people of today do not directly accept the standards of their parents who believe that they are right because they are older. so the young and adult do not understand one another. All these things generate a generation gap.
As a kind of protest against the values and lifestyles of the older people informal groups appeared. For example  such as Hippies, Rockers, Bikers, Skinheads, Punks, Goths
I believe  a great future is reserved for Modern Youth in Russia
