[单选题]Text 3 At first glance the patriarchy appears to be thriving.More than 90%of presidents and prime ministers are male,as are nearly all big corporate bosses.Men dominate finance,technology,films,sports,music and even stand-up comedy.In much of the world they still enjoy social and legal privileges simply because they have a Y chromosome.So it might seem odd to worry about the plight of men.Yet there is plenty of cause for concern.Men cluster at the bottom as well as the top.They are far more likely than women to be jailed,estranged from their children,or to kill themselves.They eam fewer university degrees than women.Boys in the developed world are 50%more likely to flunk basic maths,reading and science entirely.What can be done?Part of the solution lies in a change in cultural attitudes.Over the past generation,middte-class men have leamed that they need to help with child care,and have changed their behaviour.Working-class men need to catch up.Women have learned that they can be SUfgeons and physicists without losing their femininity.Men need to understand that traditional manual jobs arc not coming back,and that they can be nurses or hairdressers without losing their masculinity.Policymakers also need to lend a hand,because foolish laws are making the problem worse.America reduces the supply of marriageable men by locking up millions of young males for non-violent offences and then making it hard for them to find work when they get out（in Georgia,for example,felons are barred from feeding pigs,fighting fires or working in funeral homes）.A number of rich countries discourage poor people from marrying or cohabiting by cutting their benefits ifthey do.More generally,schools need to become more boy-friendly.They should recognise that boys like to rush around more than girls do:it's better to give them lots of organised sports and energy-eating games than to dose them with Ritalin or tell them off for fidgeting.They need to provide more male role models:employing more male teachers in primary schools will both supply boys with a male to whom they can relate and demonstrate that men can be teachers as well as firefighters.The growing equality of the sexes is one of the biggest achievements of the post-war era:people have greater opportunities than ever before to achieve their ambitions regardless of their gender.But some men have failed to cope with this new world.It is time to give them a hand.

[简答题]"Clean your plate !" and "Be a member of the clean-plate club ! "Just about every kid in the US has heard this from a parent or grandparent. Often, it’s accompanied by an appeal: "Just think about those starving orphans(孤儿) in Africa! "
Sure, we should be grateful for every bite of food. Unfortunately, many people in the US take a few too many bites. Instead of saying "clean the plate", perhaps we should save some food for tomorrow.
According to news reports, US restaurants are partly to blame for the growing bellies (肚子). A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story.
Americans traditionally associate quantity with value and most restaurants try to give them that. They serve large portions to stand apart from competitors and to give the customers value. They prefer to have customers complain about too much food rather than too little.
