If you ask some people, “How did you learn English so well?”you may get a surprising answer:“In my sleep!”

　　These are people who have taken part in one of the recent experiments to test learn-while-you-sleep methods (方法), which are now being tried in several countries, and with several subjects, of which English is only one.

　　Specialists(专家) say that this sleep-study method speeds language learning tremendously(巨大地). They say that the average person can learn two or three times as much during sleep as in the same period during the day－and this does not affect(影响) his rest in any way. A word of warning, however: sleep-teaching will only hammer into your head what you have studied already while you are awake.

　　In one experiment, ten lessons were broadcast(广播) over the radio at intervals of a fortnight ( two weeks). Each lesson lasted twelve hours－from: 8 p. m. to 8 a. m. The first three hours of English grammar and vocabulary were given with the student awake. At 11 p. m. a soothing (起镇静作用的) lullaby (催眠曲) was broadcast to send the student to sleep and for the next three hours the radio whispered the lesson again into his sleeping ears. At 2 a. m. a sharp noise was sent over the radio to wake the sleeping student up for a few minutes of revision (repeating a lesson ). Then he was lulled back to rest again while the radio purred on. At 5 o'clock his sleep ended and he had to go through the lesson again for three hours before his hard-earned breakfast.

To save yourself from embarrassment (尴尬)， it’s good to read a few books or research online about the culture and customs of the country you plan to visit.
Clothing: Wearing shorts in public is generally not acceptable in most parts of the world, including some European countries.
Greetings: Handshake is a usually accepted form of greeting, although in some countries, like Japan, a traditional bow(鞠躬) is preferred. Be careful how you talk with someone; don’t use first names unless you are invited to do something.
Language/Gestures: learn some polite expressions (hello-goodbye-thank you) and relax. English is pretty common worldwide, especially in tourist areas and you can always use body language to get your message across. However, some Americans gestures have different meanings in other countries. For example, in Bulgaria, shaking your head usually means  “yes”; shaking it “vertically” means “ no”.
Food/Drink: you may find yourself looking down at a local delicious snake soup in china, sheep’s eyes in Saudi Arabia… and wonder what to do; especially you are guests in someone’s home. Be brave, take small bites, and pretend it tastes like something you like. Remember that some Buddhists don’t eat beef, and Muslims don’t eat pork. If you are eating with Muslims, never touch food with left hand (the left hand is for bathroom use).
Conversations: if you know the history and culture of the country, you will be confident. The French are angry at the classic American question: “What do you do for a living?” and so on.

“Carrots，eggs and coffee，” she replied．
Her father told her to close her eyes and asked her to touch the carrots．She did so and felt that the carrots were soft．After that he asked her to take the eggs and break them．After peeling (剥开) them，she got the eggs，cooked and hard．The last，the father let her smell the coffee． She asked，“What did you do this for，Father？” He explained that each had the same unlucky experience—the boiling water，but each had a different result． The strong and hard carrots had become soft and weak．The fragile eggs became hard after being cooked． The coffee was very special，they could change water．“Who are you？” asked her father．“When bad luck knocks at your door，what is your decision? Are you carrots，eggs or coffee？”
