Questions 21 to 25 are based on the following passage
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.

Questions下列各 are based on the following passage.
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,

Symmetric, or private-key, encryption is based on ...
Symmetric, or private-key, encryption is based on a secret key that is shared by both communcating parties. The （） party uses the secret key as part of the mathematical operation to encrypt （） text to cipher text. The receiving party uses the same secret key to decrypt the cipher text to plain text. Asymmetric, or public-key, encryption uses two different keys for each user: one is a （） key known only to this one user; the other is a corresponding public key, which is accessible to anyone. The private and public keys are mathematically related by the encryption algorithm. One key ia used for encyption and the other for decryption, depending on the nature of the communication service being implemented. In addition, public key encryption technoligies allow digital （） to be placed on messages. A digital signature uses the sender&39;s private key to encrypt some portion of the message. When the message is received, the receiver uses the sender&39;s （） key tp decipher the digital signature to verify the sender&39;s identity.
