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．" 52．What problem can be related to in children if they spend a lot of time watching a screen according to the passage？D A．Backache．B．Bad eyesight． C．Heart disease．D．Getting fat． 53．What will the researchers in the Bristol University continue to do？C A．They will stop the families from watching TV． B．They will tell the children not to follow their parents'habit． C．They will search why fathers'screen time has greater effect on their daughters'． D．They will find out what kind of the harm the children suffer from． 54．What does the word"exceeding"in the passage probably mean？B A．Going down．B．Going beyond． C．Giving up．D．Putting off． 55．What does the passage mainly talk about．B A．more and more children are interested in computers． B．parents'screen time has a great effect on children's． C．fathers are more like their daughters in watching TV D．watching TV does little good to the children at all．
5．游泳是許多人夏天喜歡的運動，但是學生溺水（drown）事故時有發生．在英語課堂上，老師要求學生們就"游泳安全的注意事項"展開小組討論，并以"Swimming Safety"為題，寫一篇英語短文匯報你們的討論結果． 提示：1．do warm-up exercise（熱身運動） 2．take a life ring （救生圈） 3．call for help … 要求：1．語句通順，意思連貫，語法正確，書寫規范． 2．所有提示須用上，并提出不少于兩條的建議． 3.70詞左右（文章開頭已給出，不計入總詞數） Swimming is a favorite sport in summer，but many people have accidents when swimming，especially students．So it's very important for us to learn how to swim safely．In our group，we thinkwe must be careful and make sure to swim in a safe place first．Second，before we swim，we must do warm-up exercise．Third，we ought to take a life ring if we aren't able to swim well．Fourth，don't swim alone．Fifth，we should never get into water right after meals or when we're tired．Last but not least，if somebody is drowning，we had better call for help in time instead of saving him beyond our ability．．
