[单选题]Text 4"I like money and nice things,but it's not money that makes me happy.It's people,"says one woman in a World Bank survey.She's not alone:research has found that social integration is more important for well-being than income,and also decreases poverty.Loneliness,conversely,can be deadly:one study found it did more damage to health than smoking.This week,policymakers from 40 countries met in Colombia to ponder ways to measure deprivation that take account of more than just income,including isolation.Several Latin American countries are devising or have already adopted such"multi-dimensional"measures of poverty.Income can be a misleading measure of need because poor people end up living in different degrees of hardship depending on their intangible resources.Having strong social bonds eases financial deprivation.Friends and relatives can lend money,pool risk,mind children and bring news ofjob openings.Researchers from the London School of Economics found that when a group of Bangladeshi women were given business training and free livestock,not only djd they move up the income ladder,but their friends'lot improved too.A year later the friends'consumption had risen by almost 20%,and they claimed to have become sawier about business as well.The downside is that not having the right friends can deepen hardship.The more concentrated the poverty,the less helpful social networks tend to be.In Atlanta,living in a poor neighbourhood decreases the chance of having a friend with a job by almost 60%,and of having a friend who had been to university by over a third.A global survey conducted in 2014 by a polling firm,found that 30%of people in the poorest flfth of their country's population had nobody to rely on in times of need,compared t0 16%of the richest fifih.It is doubly unfortunate,then,that poor people are often socially excluded precisely because they are poor.Chileans and Venezuelans see poverty as a bigger cause of discrimination than gender or ethnicity,according to researchers from Oxford University.Several countries have experienced with schemes that connect lonely old people and deprived youth.Germany,for instance,has built"multi-generational"community centres where older visitors get computer coaching from teenagers.With luck,these connections will help:one American study found that in poor neighbourhoods,three-quarters ofjobholders found work through friends.Perhaps Gennany's centres will furnish income as well as company.38.The drawback of not having proper friends lies in
A.discrimination from the richest fifth.
B.loss ofchances to get university degrees.
C.no financial support from the govemment.
D.unhelpful social networks to get rid ofpoverty.

[单项选择]Art is fun; it caters to the basic creative instinct which is present in everyone. It can impart a great feeling of achievement especially to children who as yet have not been able to gain much of a sense of success from their other efforts in life. It also helps backward children to develop mentally and physically. Their confidence grows as they experience success in art, and a confident child learns more easily than a tense one. Physically handicapped children benefit because their motor control improves as they attempt to make more delicate movements with their hands and as they gradually impose more control upon themselves.
Art is particularly valuable to mentally handicapped children who find it difficult to communicate their ideas and emotions and who perhaps even find it difficult to comprehend themselves. Subnormal children with very limited vocabularies may find that painting is easier than talking, and through painting they are able to express ideas, emotions, and reac
