7.Many people like watching TV or playing computer games.But too much screen time can damage the health of adults and children.High levels of screen-viewing have been related to an increased risk of heart disease in adults,while children who spent a lot of time watching a screen are at an increased risk of being fat.
A Bristol University study suggests children are likely to spend lots of time watching TV and playing on screens if their parents do the same.Parent time spent using computers was also linked(聯(lián)系) to children's computer use,and this link was also stronger between fathers and daughters than fathers and sons.The link between fathers'and daughters'weekend screen time is particularly strong,it shows.The Bristol researchers said further research was needed to find out why this was the case.
The study looked at the children who were five or six years old from 1,000Bristol families.Parents were asked how much time they and their children spent watching TV and using a computer,or a cell phone.The study showed that 12% of boys,8% of girls in this age group watched more than two hours of TV on a weekday,with 30% of parents exceeding this level.
Figures were much higher at weekends,with 45% of boys,42% of girls,57% of fathers and 53% of mothers watching more than two hours of TV each day.Children were at least 3.4times more likely to spend more than two hours per day watching TV if their parents watched two or more hours of TV,compared to children whose parents watch less than two hours of TV.
Professor Russ Jago,from the Centre for Exercise,said,"The study results suggest that there is a need to find ways to help families reduce the amount of time that children and parents spend screen-viewing."

分析 【文章大意】這篇文章主要講述了許多人喜歡看電視或玩電腦游戲,但是過多看屏幕會損害成人和兒童的健康. 長時間看屏幕會使成人心臟病的風(fēng)險有可能增加,當(dāng)孩子花了很多時間看屏幕會增加肥胖的風(fēng)險.而有一項(xiàng)研究表明,孩子看電視的時間長短跟父母看電視時間長短而有聯(lián)系.所以我們也需要一個方法來幫助家庭減少孩子和父母看電視花的時間.
解答 52.D 細(xì)節(jié)理解題.根據(jù)文章第一段:High levels of screen-viewing have been related to an increased risk of heart disease in adults,while children who spent a lot of time watching a screen are at an increased risk of being fat.可知:長時間看屏幕會使成人心臟病的風(fēng)險有可能增加,當(dāng)孩子花了很多時間看屏幕會增加肥胖的風(fēng)險.所以此題故選D.
53.C 細(xì)節(jié)理解題.根據(jù)文章第二段:The link between fathers'and daughters'weekend screen time is particularly strong,it shows.The Bristol researchers said further research was needed to find out why this was the case.可知父親看屏幕時間的長短對女兒的影響更大. 所以他們將要來研究這個問題.故選C.
54.B 詞義轉(zhuǎn)換題.根據(jù)上文:The study showed that 12% of boys,8% of girls in this age group watched more than two hours of TV on a weekday,可知研究表明在這個年齡段的12%的男生,8%的女生在一個工作日,會看超過兩個小時的電視.由關(guān)鍵詞more than 超過可推出此處:with 30% of parents exceeding this level.
應(yīng)該是30%的父母也超過了這個水平.故選B.
55.B 主旨大意題.根據(jù)文章來看,這篇文章主要講述了孩子看電視的時間長短跟父母看電視時間長短而有聯(lián)系.所以我們也需要一個方法來幫助家庭減少孩子和父母看電視花的時間.故選B.
