In one sense, perhaps the most important sense a brand is a promise. Think of some top brands and you immediately know what they promise:McDonald’s, Coca Cola, Budweiser, Ford, Apple, MetLife. You know what you are going to get with a well-branded product or service. Think of Volvo, for instance, and your first thoughts are probably going to be something like “well built, comfortable, Swedish” and, most of all, “safety”.
The promise, look, and personality can eventually acquire a special patina(光泽) of what I call “me” appeal. Buying a certain brand says something about the person who buys it. Apple has that patina. All of this can lead to sub-brands, like iPhone and iPad which acquire the glory of the parent brand.
It takes a lot of time, money and very hard work to build and maintain great brands. That’s why I’m usually speechless when a prospective client (潜在客户) asks us for a quick “Brand”. I love developing brands from scratch but when the client needs something quick, there had better be a strong existing brand already in place.
A brand has to be memorable. Sometimes a brand is memorable because of little things. TD Bank has a special place in their branches for you to deposit all those coins you collect in jars. It is called the Penny Arcade that turns depositing your coins into a fun game in which you can even win prizes. If your kids collect coins,

you might want to open a TD account so they can enjoy the process of saving their money there.
Years ago, Dime Savings Bank in New York had a small dime(十分硬币）carrier it gave to kids who could fill up its 50 slots(窄孔）with a dime in each one(Dime Bank, get it?) and exchange it for a $5 bill. Little things can mean a lot and little things are all do-able on the smallest budget. 33. What does the example of Volvo show?
A.Branded products are not always good. B.People tend to believe in top brands. C.Well-branded products are costly. D.There are many famous brands.
34. In the author’s opinion, sub-brands______.
A.mean low profit B.are well protected C.face great challenges
D.are relatively easy to build
35.What can we infer about Dime Savings Bank’s dime carriers?
A.They sold well.
B.They were cost-efficient. C.They were quite expensive. D.They were difficult to make.
