                                                     Ten Top Tips for Your Travels

◆ Put on your most comfortable clothes and shoes when you are going for a long journey.

◆ It may be boring to travel on trains or buses, so take a good book or some interesting magazines with you.

◆ If you're going to somewhere hot, you'd better take your sun block (防晒霜) and sunglasses with you, or

     it may hurt your skin.

◆ If you're going to somewhere cold, you'd better take your warm clothes with you, or you may catch a cold. ◆ Take a camera with you so that you can take some pictures to record those special moments.

◆ Be careful with your things whenever you go to busy places, like a train station or a bus stop. There are

     often thieves there!

◆ There are some souvenirs (纪念品) in most places of interest. Leave room in your bag for them.

◆ There are some things at a discount (打折的) for students in most countries, so if you have one, take your

     student card with you in order to save your money.

◆ Bus tours often stop at expensive shops along the way. You'd better not buy souvenirs there. Instead, you

     can buy them in local shops at a lower price.

◆ Remember to take your passport with you if you travel abroad. Whatever you do, don't lose it! Most

     importantly, always remember to have fun-that's what holidays are for!
