     Some British and American people like to invite friends for a meal at home.

You should not be upset(不安的)if your English friends don't invite you home.

It doesn't mean they don't like you. 

     Dinner parties usually start between 7 and 8 p.m. and end at about 11. Ask

your hosts(主人)what time you should arrive. It's polite to bring flowers,

chocolates or a bottle of wine as a gift. 

     Usually the evening starts with drinks and snacks(小吃). If you want to be

extra polite, say how much you like the room, or the pictures on the wall. But

remember－it's not polite to ask how much things cost.

     In many families, the husband sits at one of the table and the wife sits at

the other end. They eat with their guests.

     You'll probably start the meal with soup or something small, then you'll

have meat or fish with vegetables, and then dessert(甜点心), followed by

coffee. It's polite to finish everything on your plate and to take more if you

want it.

     Did you enjoy the evening? Call your hosts the next day, or write them a

short "thank you" letter. British and American people like to say "thank you,

thank, thank you" all the time!

根据以下材料编写一个教学设计。（要求写出教学目标、教学重难点及教学过程）一、文化创新的路径（一）继承传统、推陈出新立足于社会实践，是文化创作的基本要求，也是文化创新的根本途径。在社会实践的基础上，文化创新既是一个“取其精华、去其糟粕”，改造传统文化的过程，又是一个“推陈出新、革故鼎新”，创造新文化、发展先进文化的过程。一方面，我们不能离开传统文化，空谈文化创新。任何时代的文化，都离不开对传统文化的继承：任何形式的文化，都不可能摒弃传统文化而从头开始。一个民族和国家如果漠视对传统文化的批判性继承，就会失去文化创新的根基。另一方面，体现时代精神，是文化创新的重要追求。社会实践的发展，带来了社会生活各个领域的变化，要求文化体现新的时代精神。文化创新，表现在为传统文化注入时代精神的努力之中。（二）面向世界、博采众长在社会实践的基础上，不同民族文化之间的交流、借鉴与融合，既是人类文明发展的重要动力，也是文化创新必然要经历的过程。实现文化创新，需要博采众长。文化的交流、借鉴和融合，是学习和吸收各民族优秀文化的成果，以发展民族文化的过程：是不同民族文化之间相互借鉴，以“取长补短”的过程；是在文化交流、借鉴的基础上，推出融汇多种文化特质的新文化的过程。由此可见，文化多样性是文化创新的重要基础。在文化交流、借鉴与融合的过程中，必须以世界优化文化为营养，充分吸收外国文化的有益成果。这就需要有海纳百川的胸怀、熔铸百家的气魄、科学分析的态度。不同文化之间，有差异就难免有矛盾、有竞争，但文化差异不应该成为文化交流的障碍，文化竞争并不排斥文化合作。不同民族的文化平等交流、相互借鉴，才能共同推动世界文化创新。在学习和借鉴其他民族优秀文化成果时，要以我为主、为我所用。因为永葆文化生命力和提升文化竞争力，都需要保持文化的民族特色。我们要跻身于世界文化发展的前沿，就必须深深植根于自己民族的文化土壤，不断推动中 * * 的文化创新。（三）坚持正确方向，克服错误倾向文化发展犹如一条奔腾不息的大河，要使这条大河水道畅通，水清质美，就必须清理和维护好它的源与流。对于文化创新而言，这意味着要把握好当代文化与传统文化、民族文化与外来文化的关系。那种一味固守本民族的传统文化，拒绝接受新文化和任何外来文化的倾向，被称为“守旧主义”和“封闭主义”；那种一味推崇外来文化，根本否定传统文化的倾向，被称为“民族虚无主义”和“历史虚无主义”。这些都是不利于文化创新的错误倾向，必须予以克服，才能保证文化创新沿着正确的方向、采用正确的方法进行。
