阅读下面短文,根据内容完成表格中所缺信息。(每空一词) 
Writing a thank-you letter can be a great way to express (表达)thanks  for a favor (帮助;恩惠) someone did for you. Consider these following steps when writing your letter, which will help make your thank-you letter more meaningful (有意义的) and sincere(真诚的).
Before you start, buy some special stationery, such as nice paper or blank cards. The stationery doesn’t have to be expensive, since even one-dollar card can be very nice. And you must decide whether you prefer to type your letter or write it by yourself. Handwriting has a more personal feeling, while a printed(打印的) thank-you letter looks more professional (专业的).
Now, you can start writing. You should express your purpose(目的)  from the beginning. Start your letter by thanking the person for the gift or service he or she provided. Then you should explain how you plan to use the gift or service, or explain how the gift or service has already been used. What’s more, you can also express your feelings on the gift or service by saying that “It was a wonderful birthday present…” It also helps to mention a personal feeling such as “I was just so happy with the party.” In the end, you should mention that you want to see or talk to the person again soon. For close relatives and friends, you can also tell them how much you miss them and express regret(遗憾) that their visit was short.
Sign your thank-you letter personally and with a heart. Try “Love”, “Yours truly”, or “Take care” instead (代替) of “Sincerely” as it is more for business.
In this way, you will always maintain (维持) a pleasant relationship(关系) with your friends and relatives.

如果说,清末文人们的失落造成其倡导革新而追求“现代”的话,那么,中国文人“传统”思想骨子里的抗争的确在一直压抑并释放。显然,无论继承或变革中国音乐教育,都必须在传统文化里寻找支持;他们也认识到只有依赖于“传统”,自身的“现代”才能够正统,才能够为中国固有的价值观所肯定。他们对于从西方而来的“现代”的接受在心理上是矛盾的,当猛然发现自己出现身份认同危机时,标榜自身的“传统”质地似乎是最直接而有效的手段。
这段文字意在说明( )。

A.“传统”对“现代”的发展有正本清源之作用
B.中国文人对“传统”的态度是矛盾的,既想抗争,又不得不继承
C.改革和发展都离不开“传统”
D.中国文人对西方文明的接受是矛盾的
