[单项选择]There is one kind of pain for which nobody has yet found a cure--the pain that comes from the ending of a relationship. The relationship could be a marriage or a deep friendship. Such a relationship may come to a sudden end; or it may simply fade away slowly as people and circumstances change. You may be the one to "break it off’, with a short note or a brief phone call. Or you may be on the receiving end. However it ended and whoever decided to end it, the pain is equally hard to bear and it requires the same time for grief. Although there is no cure for grief, we can not help looking for one, to ease the pain and to make us forget our tears. We keep ourselves busy with work, or we try to plunge ourselves into our hobbies. Perhaps we start to drink more than we should to "drown our sorrows", or we follow the conventional advice and join a club or society. But these things cannot cure it. Moreover, we are always in a hurry to get rid of our grief. We feel that we should try to convince

[单项选择]Age has its privileges in America. And one of the more prominent of them is the senior citizen discount. Anyone who has reached a certain age-in some cases as low as 55-is automatically entitled to a dazzling array of price reductions at nearly every level of commercial life. Eligibility is determined not by one’s need but by the date on one’s birth certificate. Practically unheard of a generation ago, the discounts have become a routine part of many businesses-as common as color televisions in motel rooms and free coffee on airliners.
People with gray hair often are given the discounts without even asking for them; yet, millions of Americans above age 60 are healthy and solvent (有支付能力的). Businesses that would never dare offer discounts to college students or anyone under 30 freely offer them to older Americans. The practice is acceptable because of the widespread belief that "elderly" and "needy" are synonymous (同义的). Perhaps that once was true, but today elderly Americans as
A. offering senior citizens discounts has become routine commercial practice
B. senior citizen discounts have enabled many old people to live a decent life
C. giving senior citizens discounts has boosted the market for the elderly
D. senior citizens have to show their birth certificates to get a discount
