The planet Earth is only a tiny part of the universe, but it's the only place where human beings can live.
Today, our planet is in serious danger. Acid rains, global warming,
air and water pollution, overpopulation are the problems that threaten
human life on Earth.
Who is to blame for the disaster? The answer is simple: all of us.
Our forests are disappearing because they are cut down or burnt. If this
trend continues, one day we won't have enough oxygen to breathe.
The seas are in danger. They are filled with poison: industrial and
nuclear waste, chemical fertilisers and pesticides. The Mediterranean is
already nearly dead; the North Sea is following. The Aral Sea is on the
brink of extinction. If nothing is done about it, one day nothing will
be able to live in the seas.
Every ten minutes one kind of animal, plant or insect dies out for
ever. If nothing is done about it, one million species that are alive
today may soon become extinct.
Air pollution is another serious problem. In Cairo just breathing the
air is dangerous — equivalent to smoking two packs of cigarettes a day.
The same holds true for many Russian cities. Factories emit tons of
harmful chemicals. These emissions have disastrous consequences for our
planet. They are the main reason for the greenhouse effect and acid
rains. An even greater threat are nuclear power stations. We all know
how tragic the consequences of the Chernobyl disaster are.
Fortunately, it's not too late to solve these problems. We have the
time, the money and even the technology to make our planet a better,
cleaner and safer place. We can plant trees and create parks for
endangered species. We can recycle litter. We can support green parties
and put pressure on those in power. Together we can save the planet and
all of us with it. Of course, people can’t stay indifferent to these
problems. There are a lot of special organizations, which try to save our
nature. The most known are: The Royal Society for the prevention of cruelty to
animals (The RSPCA), the World Wildlife Fund (WWF) and Greenpeace. The RSPCA
tries to protect animals from bad use. It operates big nation campaigns aimed
at lost pets, circus animals. The WWF rescued several species of animals,
mammals as well as birds. These organization also helped to create more than
250 National parks. Greenpeace began its work 20 years ago from saving whales.
And now Greenpeace is a world-famous organization, which saves plants, animals
and people. These organization, want to rescue animals, to help them to survive
and to save jungle rain forests, which are in danger of destruction. And they
also help animals ‘cause many of them have already gone as they have nowhere to
live. Their homes, the trees, have disappeared. We must save wild animals. And
we must find the right way to save land, people and animals. We must lake care
of nature, because we are part of it.

we answer our teacher's questions

More and more students at school and university are using the internet to cheat* in their coursework. In Britain, about 25 % of students copy material from the internet when they write their homework. In the USA there is a similar problem. One report showed that about 54 % of students copy from the internet when they prepare for the lessons.
Of course, students rightly use the internet to help them research a topic when they are doing coursework or writing an essay. But some of them also copy and include material from the internet into their own essays without indicating that they are using someone else's work. For example, a student who has to write an essay on Shakespeare can find lots of different essays on particular plays and themes in Shakespeare and copy one of them. So they no longer have to read books in libraries, take notes and plan their own essay.
The internet has certainly helped students to avoid the hard work of writing an original essay, but it is not the only reason why cheating is increasing. In recent years, students' attitudes to school and university have changed. In the past, students had a more idealistic attitude towards a university education. University broadened their minds. Nowadays, a lot of students are more practical in their attitude. They are only interested in passing the exams. They want a degree only to help them get a good job.
Teachers and examiners want to stop cheating in school and university, but they do not agree about how to solve the problem. Some teachers think a student's final grade shouldn't depend on his/her coursework. They think that it is better to have traditional (time-limited) written exams that are held in an examination room. Another way to stop cheating is to have an oral exam at the end of the course. If students cannot answer questions about their coursework, this could indicate that they have cheated. At the same time, the oral exam would give the examiner a better idea of students' real knowledge of the subject.
