Unit 1 Lifestyles 单元综合测评(一)
Ⅰ.阅读理解(共15小题；每小题2分，满分30分)
A
According to the Oxford English Dictionary，the term “couch potato” first appeared in print in a December 1979 edition of the Los Angeles Times.Since then，it has become a familiar term for a person who spends a lot of time sitting，and little time exercising.Although there does not seem to be any particular reason why the term“couch potato”is used rather than “couch tomato”，a person may become a “couch potato”because living this way is said to make you round like a potato.The term is also said to have something to do with the connection of potatoes with highcalorie(卡路里)food like potato chips.
People now would say “couch potato” whenever they talk about overweight and obesity(肥胖)．Indeed, “couch potatoes” are believed to risk heart disease，which can be avoided by r
egular exercise.
It is true that technology and modern life in general makes us sick，fat，lazy and physically/mentally soft.The more time people spend using technology，particularly televisions and computers，the less time they will spend being physically active.
“Couch potato”kids are a particular concern.Media reports repeatedly claim that children today are fatter than their elder generations，but less athletically skilled，less interested in physical activity and more addicted(上瘾的)to “junk food” and technology such as television and computers.The message is clear：today's children are fat because they are lazy and eat too much.Moreover，because technology is becoming more sophisticated(复杂的)，children are less able to resist(抵抗，忍得住)technology's attraction，and are more likely to spend more time using technology，less time doing physical activity and，therefore，more likely to be fat.

B
“Children who eat three or more hamburgers a week are more likely to suffer from asthma(哮喘)，”researchers say.However，they say that the risk may not be caused by the meatrich diet itself，but by a lack of fresh fruit and vegetables.
The study looked into 50，000 children from 20 countries.Parents were asked about their children's eating habits and whether they had ever suffered from asthma.The effects of their diet seemed to be different depending on where they lived.Fruit and vegetables are more helpful in less affluent parts of the world，while eating lots of fish was more helpful in richer countries.Eating at least three hamburgers a week was linked to a greater risk of asthma，but only in wealthier countries.
Dr.Gabriele Nagel said different things may cause asthma in different parts of the world.“This gives us more understanding of how asthma affects different people，and its effects in developing as well as developed countries，”she said.
High levels of unhealthy fat in hamburgers could increase the risk of asthma.However，the researchers said children who ate several hamburgers a week were likely to have other unhealthy lifestyle habits as well.
Researchers said the study helped us understand how asthma and diet are connected.“Previous studies have shown that a dietrich in fruit and vegetables can help to r
educe a child's risk of developing asthma symptoms，”Dr.Elaine Vickers said.“Our advice to parents is to make sure that children have a healthy diet and also get plenty of exercise.”
【语篇解读】 每周吃三次或三次以上汉堡的孩子更容易得哮喘，让孩子保持健康的饮食和适量的运动可以很好地预防儿童哮喘的发生。
