Learning the language of a country isn't enough.If you know the manners of your foreign friends, you will probably be surprised just how different they can be from your own.A visitor to India should remember it is impolite there to use the left hand for passing food at the table.The left hand is for washing yourself.Also in India, you might see a man shaking his head at another to show that he is disagreeing.But in many parts of India a side-to-side movement of the head is to show agreement.In Bulgaria you shake your head to show "yes"—a nod shows "no".In Europe it is quite usual to cross your legs while sitting and talking to someone, even at an important meeting.But doing this could cause offence to a Thailander.Touching the head of a grown-up is also not done in Thailand.Knowing about manners is useful when you are traveling, and you also need to know the language used to express the customs.1.If you are staying in India, you'd better .A.not use your left hand to pass food at the table.B.use your left hand to pass food at the table.C.not use your left hand to wash yourself.D.use your left hand at all times.2.To shake your head means “Yes” .A.in IndiaB.in EuropeC.in BulgariaD.in Thailand3.You can easily make a Thailander angry by .A.touching his headB.crossing your legs while talking to himC.shaking your headD.nodding your head4．The writer thinks that to know about a country well one must .A.know the language of the countryB.know the manners of the countryC.know the manners better than the languageD.know both the language and the manners5．We can learn from the passage that .A.different countries have different manners.B.the manners in Thailand are the same as those in India.C.one should be careful not to cross legs in Europe.D.one should not touch a grown-up's head in India.
