Put all your other stuff (and your nail scissors/leatherman/screwdrivers etc) into your suitcase or holdall or rucksack and that gets "checked" onto the plane when you arrive at the airport.  Sometimes you need to reclaim it on entering an country (we do when travelling from the UK to the US) and then re-check it onto your on-going flight, more often than not it is checked right through to your final destination.

If your flight is long enough to have a film or audio entertainment take your own comfortable headphones, but you will need an adaptor to fit the plane twin-socket.  Wear comfortable clothes and shoes which slip on and off.  Remember that you will have to go though a metal detector gate so a jacket which slips off easily is also a good idea - put all our small change, keys and cell phone in your jacket pocket to go through the X-ray machine.  Don't forget to take the pocket knife off your keyring and leave it at home or put it in your big luggage.

Take a good book or three, there can be lots of waiting around.

Oh yes, and HAVE FUN!

 Nowadays there are about six thousand languages around the world. But many languages are endangered. And even greater number s are extinct. At all times,   language was not only a means of communication, but also part of cultural heritage. Languages vanish when their last speaker dies. With them dwindles the world’s culture and a piece of history disappears. For example, in the works of the well-known British linguist David Crystal, the formerly unknown to the world Kasabe language was recovered. Its last native speaker died in 1996, leaving absolutely no information about the language and its history. So, what will happen to the world if languages continue to disappear? Rare languages will disappear first. As a result, many centuries later the "giant" languages’ turn will comes. This means that some day people will lose their ability to communicate with each other, world culture will be devastated, a general degradation will start. Humanity will return to the primitive age. Do we want such an outcome?
Прежде, чем работать над грамматикой, надо бы поработать над стилистикой.
А то, коряво местами, не говоря уже о том, что - спорно. Но это уже вопрос к автору.
