在中国文化中，黄颜色是一种很重要的颜色，因为它具有独特的象征意义。在封建(feudal)社会中，它象征统治者的权力和权威。那时，黄色是专为皇帝使用的颜色，皇家宫殿全都漆成黄色，皇袍总是黄色的，而普通老百姓是禁止穿黄色衣服的。在中国，黄色也是收获的象征。秋天庄稼成熟时，田野变得一片金黄。人们兴高采烈，庆祝丰收。

Section C
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A),B),C) and D).You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.
Passage One
Questions 46 to 50 are based on the following passage.
As a person who writes about food and drink for a living. I couldn’t tell you the first thing about Bill Perry or whether the beers he sells are that great. But I can tell you that I like this guy. That’s because he plans to ban tipping in favor of paying his servers an actual living wage.
I hate tipping.
I hate it because it’s an obligation disguised as an option. I hate it for the post-dinner math it requires of me. But mostly, I hate tipping because I believe I would be in a better place if pay decisions regarding employees were simply left up to their employers, as is the custom in virtually every other industry.
Most of you probably think that you hate tipping, too. Research suggests otherwise. You actually love tipping! You like to feel that you have a voice in how much money your server makes. No matter how the math works out, you persistently view restaurants with voluntary tipping systems as being a better value, which makes it extremely difficult for restaurants and bars to do away with the tipping system.
One argument that you tend to hear a lot from the pro-tipping crowd seems logical enough: the service is better when waiters depend on tips, presumably because they see a benefit to successfully veiling their contempt for you. Well, if this were true, we would all be slipping a few 100-dollar bills to our doctors on the way out their doors, too. But as it turns out, waiters see only a tiny bump in tips when they do an exceptional job compared to a passable one. Waiters, keen observers of humanity that they are, are catching on to this; in one poll, a full 30% said they didn’t believe the job they did had any impact on the tips they received.
So come on, folks: get on board with ditching the outdated tip system. Pay a little more upfront for your beer or burger. Support Bill Perry’s pub, and any other bar or restaurant that doesn’t ask you to do drunken math.
What can we learn about Bill Perry from the passage？

A. He runs a pub that serves excellent beer.
B. He intends to get rid of the tipping practice.
C. He gives his staff a considerable sum for tips.
D. He lives comfortably without getting any tips.
