Compared to other parts of the body, our ears don’t ask for much. They don’t need to be brushed once a day like your teeth. But they meed some special care, especially if you like listening to music with earphones.

Maybe your mum or dad has told you,“Turn that down before you go deaf!” Well, they are quite right. Loud noise might cause hearing loss for a short time or even forever. Think that earphones are a good way to escape from tour parents’ eyes? Well. It may not be as good a way as you expect. American doctors have studied a group of 44,000 people who used earphones more than 15 hours per week. The doctors found that 37,000 of them were getting hearing problems.

If you use earphones for to8 long a time, your ears might feel painful. You could also lose your hearing for the rest of your life. So don’t wear your earphones too long. Use them less than one hour a day. Want sharp hearing? Don’t forget to do the following: Try to stay away from places where there is too much noise, like a disco. If you have to go, wear earplugs. When swimming, remember to put earplugs into your ears to stop water from getting in. Never put anything sharp into your ears. If you think you have too much earwax, ask your mum or dad to help you clean it out.

Keep these things in mind! Then you won’t be saying “WHAT???” when you are older.

TIPPING

How much and who on your cruise(乘船旅游) should be tipped? When and how should tips be given? Generally, you should plan to tip your room steward (服务员) $3.00 to $3.50 per person, per day, and plan an equal amount for your dining room waiter, and half of that for the busboy(餐厅侍者助手).

On most ships, tip the maitre d’(侍者总管) or dining room captain only if you ask for special favors or table-side service; $5 to $10 is normal. Barmen and wine stewards are tipped 10 to 15 percent, but many cruise lines will add this tip to your bar or drink bill. Check the bill to see how it is handled. Also, tips for special services such as salon && spa treatments and room service are left to the guest, depending on services offered. Sometimes tips are placed in envelopes from your cabin’s stationery supply. Generally, passengers on cruises of 10 days or less will tip at the end of the cruise; on longer voyages, tipping weekly.

As part of a new trend that seems likely to grow, Carnival, Holland America, Norwegian, Princess and Cunard now charge tips to your account (账). Norwegian, for example, charges $10 per day, per guest, to cover service in the various dining rooms and your room steward. If you feel this amount needs to be increased or decreased, arrangements can be made onboard the ship, generally at the end of your cruise.

A few lines do not encourage tipping, including Radisson Seven Seas, Seabourn, Silversea and Windstar. Crew members are reportedly higher paid and not tip dependent. Many passengers tip anyway for outstanding service or special favors and give them tips face to face immediately they get serviced.
