However,with my terrible Chinese tones,I made a mistake by asking "Have you by any chance sat upon a flying cock?" So you can imagine how I really felt inside my mind at that moment!You know what it means by speaking in such an uncomfortable tune to a female teacher!Then I changed my languages and chatted with her in German,French and Russian in brief.God Heavens!My female Chinese teacher finally reacted and turned her red face to normal!Indeed this is the only time in my adult life when I haven't been learning a language.Languages have changed my life-and enriched it.And I think they can change yours too.1.In the writer's eyes,the loss of using a language can be obtained .A. by practicing it more oftenB. from a zero level recordC. by learning the pointsD. from a Chinese teacher2.The writer was not very good at languages at school because .A. he hated speaking Chinese with female peopleB. he didn't learn languages very effectivelyC. his French tests were always a zero recordD. his Chinese teachers taught him in a bad way3.The mistake with the female teacher at the party .A. would make the writer more confident of his Chinese levelB. would certainly bring the writer a severe punishmentC. brought the writer into a very embarrassing situationD. would make her think highly of his Chinese level4.The writer turned to other languages to talk to his teacher in order to .A. warn people not to make any mistakes in official languageB. advise people to try using more languages to talk with othersC. suggest a diversity of changes of languages in people's lifeD. relieve the tense atmosphere to make her relaxed
