Text 2 A century ago,the immigrants from across the Atlantic included settlers and sojourners.Along with the many folks looking to make a permanent home in the United States came those who had no intention to stay,and 7million people arrived while about 2 million departed.About a quarter of all Italian immigrants,for example,eventually returned to Italy for good.They even had an affectionate nickname,“uccelli di passaggio,”birds of passage.Today,we are much more rigid about immigrants.We divide newcomers into two categories:legal or illegal,good or bad.We hail them as Americans in the making,or brand them as aliens to be kicked out.That framework has contributed mightily to our broken immigration system and the long political paralysis over how to fix it.We don't need more categories,but we need to change the way we think about categories.We need to look beyond strict definitions of legal and illegal.To start,we can recognize the new birds of passage,those living and thriving in the gray areas.We might then begin to solve our immigration challenges.Crop pickers,violinists,construction workers,entrepreneurs,engineers,home healthcare aides and physicists are among today's birds of passage.They are energetic participants in a global economy driven by the flow of work,money and ideas.They prefer to come and go as opportunity calls them.They can manage to have a job in one place and a family in another.With or without permission,they straddle laws,jurisdictions and identities with ease.We need them to imagine the United States as a place where they can be productive for a while without committing themselves to staying forever.We need them to feel that home can be both here and there and that they can belong to two nations honorably.Accommodating this new world of people in motion will require new attitudes on both sides of the immigration battle.Looking beyond the culture war logic of right or wrong means opening up the middle ground and understanding that managing immigration today requires multiple paths and multiple outcomes,including some that are not easy to accomplish legally in the existing system.
The author suggests that the birds of passage today should be treated____

A.as faithful partners
B.with economic favors
C.with legal tolerance
D.as mighty rivals

Text 1 Ruth Simmons joined Goldman Sachs's board as an outside director in January 2000;a year later she became president of Brown University.For the rest of the decade she apparently managed both roles without attracting much criticism.But by the end of 2009 Ms.Simmons was under fire for having sat on Goldman's compensation committee;how could she have let those enormous bonus payouts pass unremarked?By February the next year Ms.Simmons had left the board.The position was just taking up too much time,she said.Outside directors are supposed to serve as helpful,yet less biased,advisers on a firm's board.Having made their wealth and their reputations elsewhere,they presumably have enough independence to disagree with the chief executive's proposals.If the sky,and the share price,is falling,outside directors should be able to give advice based on having weathered their own crises.The researchers from Ohio University used a database that covered more than 10，000 firms and more than 64，000 different directors between 1989 and 2004.Then they simply checked which directors stayed from one proxy statement to the next.The most likely reason for departing a board was age,so the researchers concentrated on those“surprise”disappearances by directors under the age of 70.They found that after a surprise departure,the probability that the company will subsequently have to restate earnings increases by nearly 20%.The likelihood of being named in a federal classaction lawsuit also increases,and the stock is likely to perform worse.The effect tended to be larger for larger firms.Although a correlation between them leaving and subsequent bad performance at the firm is suggestive,it does not mean that such directors are always jumping off a sinking ship.Often they“trade up，”leaving riskier,smaller firms for larger and more stable firms.But the researchers believe that outside directors have an easier time of avoiding a blow to their reputations if they leave a firm before bad news break,even if a review of history shows they were on the board at the time any wrongdoing occurred.Firms who want to keep their outside directors through tough times may have to create incentives.Otherwise outside directors will follow the example of Ms.Simmons,once again very popular on campus.
According to the researchers from Ohio University,after an outside director's surprise departure,the firm is likely to_____

A.become more stable
B.report increased earnings
C.do less well in the stock market
D.perform worse in lawsuits
