There are two types of people in the world.Although they have equal degree of health and wealth and other comforts of life, one becomes happy, while the other becomes unhappy.This arises from the different ways in which they consider things, persons, events and the resulting effects upon their minds. People who are to be happy fix their attention on the convenience of things: the pleasant parts of conversation, the well prepared dishes, the goodness of the wine and the fine weather.They enjoy all the cheerful things.Those who are to be unhappy think and speak only of the opposite things.Therefore, they are continually dissatisfied.By their remarks, they sour the pleasure of society, offend(hurt) many people, and make themselves disagreeable everywhere.If this turn of mind was founded in nature, such unhappy persons would be the more to be pitied.The intention of ccriticizing and being disliked is perhaps taken up by imitation.It grows into a habit, unknown to its possessors.The habit may be strong, but it may be cured when those who have it realize its bad effects on their interests and tastes.I hope this little warning may be of service to them, and help them change this habit. Though in fact it is chiefly an act of the imagination, it has serious results in life since it brings on deep sorrow and bad luck.Those people offend many others; nobody loves them, and no one treats them with more than the most common politeness and respect.This frequently puts them in bad temper and draws them into arguments.If they aim at getting some advantages in social position or fortune, nobody wishes them success.Nor will anyone start a step or speak a word to favor their hopes.If they bring on themselves public objections, no one will defend or excuse them, and many will join to criticize their wrong doings.These should change this bad habit and be pleased with what is pleasing, without worrying needlessly about themselves and others.If they do not, it will be good for others to avoid any contact with them.Otherwise, it can be disagreeable and sometimes very inconvenient, especially when one becomes mixed up in their quarrels. 21.According to the passage，those who are unhappy _______. A.always consider things differently from others B.are usually influenced by the result of certain things C.can discover the unpleasant part of certain things D.usually have the habit of finding faults with others 22. Which of the following statements is NOT true according to the passage？ A.All the unhappy people should be pitied even more. B.The unhappy people are critical about everything. C.Most unhappy people want to get rid of their habit. D.The unhappy people are not content with themselves. 23. The phrase "sour the pleasures of society" (Para. 2) most probably means "__________". A.enjoy the displeasure of society B.feel happy with the pleasures of society C.make the company of others less enjoyable D.become discontent with their nation 24. The unhappy people&39;s habit can cause serious consequences. Which of the following is NOT one of the consequences according to the passage？ A.When the unhappy people want to succeed, no one wishes them to. B.The unhappy people can offend many other people without knowing. C.It brings on deep sorrow to the unhappy people themselves as well as others. D.Many people may join to criticize the unhappy people&39;s misconduct. 25. According to the author, if such unhappy people will not change their bad behavior, the solution to the problem is that __________. A.people should understand and forgive them B.people should avoid contact with them C.people should help them get rid of the bad habit D.people should show more respect to them

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 group have a lower poverty rate than the rest of the population. To be sure, there is economic diversity within the elderly, and many older Americans are poor, But most of them aren’t. It is impossible to determine the impact of the discounts on individual companies. For many firms, they are a stimulus to revenue. But in other cases the discounts are given at the expense, directly or indirectly, of younger Americans. Moreover, they are a direct irritant in what some politicians and scholars see as a coming conflict between the generations. Generational tensions are being fueled by continuing debate over Social Security benefits, which mostly involves a transfer of resources from the young to the old. Employment is another sore point, Buoyed (支持) by laws and court decisions, more and more older Americans are declining the retirement dinner in favor of staying on the job-thereby lessening employment and promotion opportunities for younger workers. Far from a kind of charity they once were, senior citizen discounts have become a formidable economic privilege to a group with millions of members who don’t need them. It no longer makes sense to treat the elderly as a single group whose economic needs deserve priority over those of others. Senior citizen discounts only enhance the myth that older people can’t take care of themselves and need special treatment； and they threaten the creation of a new myth, that the elderly are ungrateful and taking for themselves at the expense of children and other age groups. Senior citizen discounts are the essence of the very thing older Americans are fighting against-discrimination by age. 31. We learn from the first paragraph that ________. 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

A newstudy shows a large gender gap on economic policy among the nations professional economists,a divide similar to the gender divide found in the general public. "Asa group, we are pro-market," says Ann Marl May, co-author of the study anda University of Nebraska economist. "But women are more likely to acceptgovernment regulation and involvement in economic activity than our malecolleagues. " "Itsvery puzzling," says free market economist Veronique de Rugy of the Mercatus Center at George Mason University. "Not a .day goes by that Idont ask myself why there are so few women economists on the free market side." A nativeof France, de Rugy supported government intervention (干预) early in her life butchanged her mind after studying economics. "We want many of the samethings as liberals--less poverty, more health care--but have radicallydifferent ideas on how to achieve it. " IAberaleconomist Dean Baker, co-founder of the Center for Economic Policy andResearch, says male economists have been on the inside of the profession,confirming each others antiregulation views. Women, as outsiders, "aremore likely to think independently or at least see people outside of theeconomics profession as forming their peer group," he says. Thegender balance in economics is changing. One-third of economics doctorates (博士学位) now go to women."More diversity is needed at the table when pubflc policy isdiscussed," May says. Economistsdo agree on some things. Female economists agree with men that Europe has toomuch regulation and that Wal-mart is good for society. Male economists agreewith their, female colleagues that military spending is too high. Thegenders are most divorced from each other on the question of equality forwomen. Male economists overwhelmingly think the wage gap between men and womenis largely the result of indi~fluals skills, experience and voluntary choices.Female economists overwhelmingly disagree by a margin of 4-to-1. Thebiggest disagreement: 76% of women say faculty opportunities in economics favormen. Male economists point the opposite way: 80% say women are favored or theprocess is neutral. What is the finding of the new study？ A.The gender divide is a big concern of the general public. B.Men and women understand economics quite differently. C.The gap between male and female economists needs to be closed. D.Male and female economists disagree widely on economic policy,
