21.It’s important to be on your guard when you are traveling to foreign countries. We’ve all heard the stories of unwilling travelers having their wallets stolen or finding themselves in the wrong part of town. Read the following tips and find out how you can stay safe while traveling abroad.
First, you’d better carry a small amount of cash and a copy of your ID with you at all times. There is no need to bring large amounts of cash with you. Use your credit card instead. Second, don’t forget to lock your valuable things either in the safe in your hotel room or in the main hotel safe. Third, keep your wallet in your front pocket. For the ladies, it’s better to take a small purse under your arm so that there is no way someone’s hand could get in there without you noticing it. Fourth, be aware of your surroundings. Look around when walking, and avoid keeping your head low or being in a sleepy or drunk condition. Fifth, you should always know where you’re going. Look at the map before you leave the hotel so that you know where you’re going and how to get there.
Finally, it will be a good choice to travel with your family, a friend, or a business partner if possible. It’s always better to travel in pairs than to go alone.(10分)
