2 . Travel tips for holidays abroad

Everyone loves holiday abroad. They give us the chance to see some sights, have some fun and relax. However, holidays aren’t always a great experience. Follow these tips to make sure you enjoy your holiday.

    1    

Have you packed your passport? Your tickets? Every year, thousands of people miss flights because they’ve forgotten their passports, they arrive at the airport too late, or even go to the wrong airport !

    2    

How much do you know about the place you are going to visit? Learning a little about the culture of a country will help you understand the people. Learning a few words of another language can also help you make new friends.

    3    

Try to reduce the pollution you cause. Travel by train if you can. Flying produces twenty times more carbon dioxide（二氧化碳） than travelling by train. Of course, it might be impossible to avoid flying, but when you arrive, use buses or trains instead of taxis.

    4    

You can help a local community a lot by staying in local hotels and eating in local restaurants. This means that your money will go to local people, rather than to a large international company.

    5    

You don’t want to forget your holiday. Make a scrapbook—a book of memories about your holiday. You can show it to friends, or just use it to remember all the good times you had! And don’t forget the new friends you made on holiday. Did you promise to send them pictures or presents? Don’t forget to do it! Then next time you go on holiday, you can visit them again.

A．Remember the environment.

B．Keep a good memory for your holiday.

C．Do some research.

D．Get organized.
