But when we plant non-native plants,we are clobbering the food chain,because then we dont have the insects the birds need to live.”Fewer of the right plants mean fewer bugs,and fewer bugs mean fewer birds.And thats bad for the Earth,because we need a variety of living things to keep the planet healthy and beautiful.The good news is,garden centers sell native plants.“Just Google native plantsand your location,and you can find out which plants really belong where you live,”says Tallamy26.

The effect was first noted in 1858 by William Farr,who who wrote that widows and widowers（鳏夫）were at a much higher risk of dying than their married peers.Studies since then suggest that marriage could add as much as seven years to a mans life and two to a womans.The effect holds for all causes of death,whether illness,accident or self-harm. Even if the odds are stacked against you(the conditions are not favourable),marriage can more than compensate.Linda Waite of the University of Chicago has found that a married older man with heart disease can expect to live nearly four years longer than an unmarried man with a healthy heart.Likewise,a married man who smokes more than a pack a day is likely to live as long as a divorced man who doesnt smoke.Theres a flip side,however,as partners are more likely to become ill or die in the couple of years following their spouses; death,and caring for a spouse with mental disorder can leave you with some of the same severe problems.Even so,the odds favour marriage.In a 30-year study of more than 10,000 people,Nicholas Christakis of Harvard Medical School describes how all kinds of social networks have similar effects.So how does it work?The effects are complex,affected by socio-economic factors,health-service provision,emotional support and other more physiological mechanisms(机制).For example,social contact can boost development of the brain and immune system,leading to better health and less chance of depression later in life.People in supportive relationships may handle stress better.Then there are the psychological benefits of a supportive partner.A life partner,children and good friends are all recommended if you aim to live to 100.The best social network is still being mapped out,but Christakis says:”People are interconnected,so their health is interconnected.”41. William Farrs study and other studies show that_.A. social life provides an effective cure for illnessB. Being sociable helps improve ones quality of lifeC. Women benefit more than men from marriageD. Marriage contributes a great deal to longevity【答案】D【解析】细节理解题。根据the biggest longevity(长寿)boost seems to come from marriage or an equivalent relationship.故选D。42. Linda Wa
