Brand refers to names, logos and slogans. For example, Nike is known for its slogan “Just do it” and swoosh logo. A trademark shows the origin and ownership of a product or service, which is used to protect names, logos, drawings, symbols and other characters related with a business. Coke？ and Coca-cola？ are registered trademarks of the Coca-Cola Company.
Many companies spend a lot of money and time registering their trademarks. There are at least two good reasons for this. Firstly, if you trademark a brand, you are the only person allowed to use that Brand name slogan etc. If others want to use that brand, they must ask your permission or pay some money. Secondly, registration also allows the owner to bring legal action against anyone who uses the trademark without authorization.
There are basic trademark symbols, e.g.“TM”for goods and“SM”for service.They tell the public that the product's name and design are the exclusive property of the company, but a registered trademark？ provides notice that it has indeed been registered.
The trademark symbols TM and ? can be exchanged in a brand.

[单项选择]If women are mercilessly exploited year after year, they have only themselves to blame. Because they tremble at the thought of being seen in public in clothes that are out of fashion, they are always taken advantage of by the designers and the big stores. Clothes which have been worn only a few times have to be put aside because of the changes of fashion. When you come to think of it, only a woman is capable of standing in front of a wardrobe packed full of clothes and announcing sadly that she has nothing to wear.
Changing fashions are nothing more than the international creation of waste. Many women spend vast sums of money each year to replace clothes that have hardly been worn. Women who cannot afford to throw away clothing in this way, waste hours of their time altering the dresses they have. Skirts are lengthened or shortened; neck-lines are lowered or raised, and so on.
No one can claim that the fashion industry contributes anything really important to society. Fas

[简答题]Obama’s success isn’t all good news for black Americans
As Erin White watched the election results head towards victory for Barack Obama, she felt a burden lifting from her shoulders. "In that one second, it was a validation for my whole race," she recalls.
"I’ve always been an achiever," says White, who is studying for an MBA at Vanderbilt University in Nashville, Tennessee. "But there had always been these things in the back of my mind questioning whether I really can be who I want. It was like a shadow, following me around saying you can only go so far.
